VMware VMmark Wins, Powered By AMD EPYC Virtual Tasks
Tumblr media
VMmark User Guide
After their introduction in 2017, AMD EPYC processors have become the preferred option for both public and private cloud deployments. High core counts, the fastest x86 memory bandwidth in the market, and cutting-edge security features make 4th generation AMD EPYC processors ideal for demanding private cloud workloads. AMD EPYC processors offer a strong platform for building private cloud infrastructures, as do VMware by Broadcom products including VMware Cloud Foundation (VCF) and VMware vSphere Foundation (VVF), which comprise programmes like vSphere, vCenter, vSAN, and NSX. The strategic partnership between AMD and VMware By Broadcom helps organisations install and manage virtualized environments that meet their performance and scalability needs while optimising energy efficiency and TCO.
Two typical deployment scenarios for VCF/VVF exist:
Conventional VVF infrastructure typically comprises discrete networking, storage, and computation gear. Running this model requires managing each part independently, which frequently calls for specialised knowledge and equipment, but it produces the best results. The computational component is virtualized using software like VMware vSphere, which is controlled by a virtual infrastructure administrator. This configuration’s storage component depends on specialised Storage Area Network (SAN) or Network Attached Storage (NAS) devices under the control of a Storage Administrator. A contemporary method of managing data centres is called hyper-converged infrastructure (HCI), which integrates networking, storage, and processing into a single, cohesive system. Typically, HCI systems pool storage resources throughout the entire infrastructure for simple scaling and management by a Virtual Infrastructure Administrator. This is made possible by Software Defined Storage (SDS), which is made possible by products like vSAN. Compared to conventional VCF/VVF installations, this simplified method can maximise savings while enhancing agility and scalability. VMmark Benchmark
By offering thorough performance measurements that mimic real-world workloads to evaluate CPU, memory, storage, and networking performance, the VMmark benchmark helps enterprises to evaluate the effectiveness and scalability of their virtualized systems. Businesses may decide on hardware configurations, resource allocation, and workload management methods with knowledge thanks to this comprehensive picture of system capabilities under various workload scenarios.
By applying the smallest unit, or “tile,” of load, VMmark3 employs a weighted scoring system to assess a server’s performance. Nineteen virtual machines are included of each tile, which represents a typical enterprise virtualization scenario by executing a wide collection of tasks both concurrently and collaboratively. Each tile’s static nature allows for the size and scalability of the amount of work for every distinct VMmark3 cluster.
With a growth in hosts, sockets, and cores, there are usually more tiles. Each tile also serves as a representation of the maximum theoretical score and a Quality of Service (QoS) metric, which are used to appropriately scale each publication: an excessive number of tiles exceeds the benchmark latency requirements, while an insufficient number of tiles limits the maximum score.
While application performance accounts for a piece of the total score, the quantity of tiles is essential to comprehending the potential of a VCF deployment. Many of the capabilities that are exclusive to VCF, like XvMotion, Storage vMotion, vMotion, and the Distributed Resource Scheduler (DRS), are also utilised by standard virtualized deployments. By utilising these capabilities, VMmark workloads offer a more comprehensive view of what can be accomplished with the entire system as opposed to just one server. Depending on the underlying technology, these infrastructure processes can vary in scope and duration, accounting for 20% of the total score.
Benefits of Generational Performance AMD is committed to innovation and keeps delivering notable gains in efficiency and performance for important applications. As can be seen in Figure 1, AMD EPYC processors have significantly improved in performance with each iteration when used in VCF scenarios. These assessments include single- and dual-processor installations in both normal settings and vSAN configurations. The consistent dedication of AMD towards meeting the dynamic and ever-increasing demands of contemporary virtualized infrastructures is demonstrated by the notable performance improvements attained with every new generation of AMD EPYC CPUs.
Performance of Throughput
Thanks to continued AMD processor technology advances and collaborative VMware By Broadcom optimisations, the preceding section of this blog revealed constant performance increases across successive AMD EPYC processor generations. The performance domination of AMD EPYC processors over several processing generations is demonstrated in Figure 2, which highlights their unwavering commitment. In VMmark3 performance tests conducted on clusters comprising two dual-socket servers for a total of four processor sockets, the 4th generation AMD EPYC 9654 CPU outperforms even the most recent 5th generation Intel Xeon Platinum 8592+ processor.
Per-Core Efficiency
When it comes to power, space, and server count optimisation, per-server throughput is a crucial measure. Additionally, because per-core performance is frequently a major issue in software licencing models based on core count, it is especially important for workloads that are SLA-critical.
The performance improvements of 32-core AMD EPYC 9374F processors over 32-core Intel Xeon Gold 6548Y+ processors and 64-core AMD EPYC 9554 processors over 64-core 5th Gen Intel Xeon 8592+ processors are shown in Figure 3.
Power Effectiveness
In order to minimise cooling requirements, maximise utility costs, and support sustainability goals, modern data centres must have efficient power consumption. In comparison to both 4th and 5th Gen Intel Xeon processors, Figure 4 illustrates how 4th Gen AMD EPYC 9654 CPUs provide higher power efficiency.
Space for a Data Centre VMmark Scores Data centres have tremendous incentives to optimise space, electricity, and cooling for sustainability and TCO. Less servers that may offer more virtual machine consolidation without sacrificing the speed required for corporate operations can be used to achieve these goals. Suppose AMD workloads need to achieve business objectives with resources and quality of service equal to a total VMmark3 score of 500. This aggregate score can be attained with just 26 servers running 4th Gen AMD EPYC 9654 processors, as shown in Figure 5.
AMD will require 38 servers if they choose to employ servers with 5th generation Intel Xeon 8592+ processors. It may take up to 112 servers for customers with 2nd Gen Intel Xeon 8280 processor-based servers to get the same aggregate score! That’s more than 4 times the amount of AMD EPYC 9654 processor-based servers required to meet the same workload in business! This comparison emphasises the significance of not only power efficiency but also making the best use of server rack space in datacenters.
VMmark Benchmark Results This article demonstrated how VMmark victories and the next generation of AMD EPYC processors can drive consistent performance leadership, giving organisations optimal hardware consolidation and unparalleled x86 workload performance that may help reduce total cost of ownership. Businesses can safely depend on AMD EPYC processors to satisfy their changing virtualized infrastructure demands while maximising available power and capacity. Together, AMD and VMware by Broadcom are still dedicated to promoting innovation that continuously yields record-breaking virtualized environment performance and efficiency. Businesses can achieve new levels of agility, scalability, security, and reliability in their IT infrastructures by utilising Broadcom’s combination of experience in AMD and VMware.

New Post has been published on VMware Virtualization Blog
New Post has been published on https://www.tayfundeger.com/vsan-capacity-reserve.html
vSAN Capacity Reserve
Merhaba,
vSAN Capacity Reserve isimli bu yazımda sizlere, vSAN’ın yeni özelliklerinden biri olan vSAN Capacity Reserve hakkında detaylı bilgi vereceğim. Daha önce yazmış olduğum vSAN makalelerine aşağıdaki linkten ulaşabilirsiniz.
https://www.tayfundeger.com/kat/VSAN
Daha önceki makalelerimde sürekli belirtmiştimdir. vSAN kullanıyorsanız doluluk oranlarına dikkat etmeniz gerekiyor. Kapasitenin %25 veya %30 ‘unu boş bırakmanız gerekiyor. Bunun sebebi aslında hem rebuild işlemleri hemde policy üzerinde yapacağınız bir değişiklikte free alan’ın azalmasına sebep olmasından kaynaklanıyor. vSAN rebuild, repair gibi işlemlerde free alanı kullanır. Hatta bu konu ile ilgili yazmış olduğum yazılara aşağıdaki linkten ulaşabilirsiniz.
VSAN – Resyncing Objects
SAN ve Arıza Senaryoları
VSAN – Advanced Options
vSAN Capacity Reserve
vSAN cluster’ında bir ESXi host’un down duruma gelmesi durumunda rebuild işlemi başlayacağı için bu free kapasite kullanılır. VSAN 7 U1’den önceki sürümlerde, önerilen free space’in takip edilmesi için vCenter Server alarm’larından veya vROPS gibi ürünlerden faydalanmak zorunda kalıyoruz. vSAN 7 U1 den itibaren artık bu free space’i özel olarak takip etmemize gerek bulunmuyor. vSAN ile birlikte gelen Reserved Capacity özelliği sayesinde,  kapasitenin kritik değerleri aşmasını önlenmesine olanak sağlıyor.
Yukarıda da belirttiğim gibi rebuild ve repair işlemleri için free space kullanılırken, Storage Policy üzerinde değiştireceğiniz bir object konfigurasyonundan kaynaklı free space’i de kullanabilirsiniz. Örneğin disk kopyasını değiştirmeniz durumunda free space’de değişim olur. Çünkü var olan virtual machine’in disklerinin farklı bir diske senkronize olurken free space’in bir miktarını kullanır. Free space’i etkileyen bu şekilde etkenler bulunuyor iken, reserved capacity tam burada işimize yarıyor.
vSAN Capacity Reserve aktif etmenin 2 farklı yolu bulunuyor. İsterseniz vSAN cluster’ını seçip Configuration > vSAN Services Enable Capacity Reserve butonuna basabilirsiniz. İsterseniz de Monitor > Capacity bölümüne giriş yaptığınızda aşağıdaki bir ekran ile karşılaşırsınız.
vSAN Capacity Reserve
Burada, You can enable operations and host rebuild reserve yanında yer alan Configure butonuna basıyoruz.
Enable Capacity Reserve bölümüne giriş yaptığımızda karşımıza 2 adet seçenek çıkıyor.
Operations reserve: vSAN’ın cluster’daki internal işlemlerini yürütmek için ihtiyaç duyduğu alanı görüntüler . Kullanılan alan işlem eşiğini aşarsa, vSAN düzgün çalışmayabilir. Örneğin storage policy üzerinde bir ayar değiştirceksiniz ve bu değiştirdiğiniz ayar sonucunda vSAN cluster’ı içerisinde bulunan virtual machine dosyalarının senkronizasyon edilmesi gerekecek. Bu gibi durumlarda Operations reserve seçeneğini aktif durumda olur ise altyapımızı riske atmadan sorunsuz bir şekilde işlemlerimize devam edebiliriz.
Host rebuild reserve: Host rebuild reserve ise, bir ESXi host’un kapasitesine göre ayarlanmıştır. Bir vSAN Cluster’ında bir ESXi host arızalanırsa veya down olursa diyelim, b��yle bir durumda üzerindeki diskleri kullanamaz ve bundan dolayı vSAN cluster’ındaki depolamaya katkıda bulunamaz. Bu gibi durumlar oluştuğunda cluster’da repair/rebuild işlemleri başlanır. Bu konu ile ilgili yazmış olduğum makalelere yukarıdaki linkten ulaşabilirsiniz. Rebuild/Repair işlemlerinin yapılabilmesi için bir kapasiteye ihtiyaç bulunmaktadır. Eğer bu kapasite bulunmaz ise rebuild/repair işlemleri başarısız olablir. Host rebuild reserve sayesinde bu gibi kapasite ihtiyaçlarını kontrol etme imkanına artık sahibiz. Bu özellik default olarak devre dışıdır. Özelliği aktif edebilmek için Operations reserve’i ilk olarak aktif etmeniz gerekmektedir.
Capacity Reserve’i aktif etmezseniz, kapasitenin tükenmesi durumunda virtual machine’lerin oluşturulmasını veya virtual machine’lerin çalışması engellenir. Capacity Reserver’i aktif ederseniz, vSAN eşik sınırlarına ulaştıktan sonra bile virtual machine’den gelen IO talepleri karşılanmaya devam eder. Capacity Reserve etkinleştirdikten sonra, cluster’daki disk alanı, sağlık uyarılarını ve kapasite kullanımını izlemeli ve kapasite kullanımını eşik sınırlarının altında tutmak için uygun eylemleri gerçekleştirmelisiniz.
Bu özelliği kullanabilmeniz için bazı gereksinimleri karşılamanız gerekiyor. Capacity Reserve’i; Stretched Cluster, fault domain, ROBO Cluster ve vSAN Cluster’ı 4 node’dan az ise bu özelliği kullanamazsınız. Ayrıca vSAN Cluster’ında eşik değerinden yüksek bir kapasiteye sahipse zaten Capacity Reserve’i aktif edemezsiniz.
vSAN ‘ın yeni sürümleri ile birlikte sürekli yeni özellikler gelmeye devam ediyor. Capacity Reserve özelliğide vSAN ortamımı hem güvenli bir şekilde yönetmemize hemde operasyonel işlemler için gerekli tahmini boş kapasitenin dinamik olarak hesaplanmasını sağlıyor. Ayrıca cluster’ın kritik kapasite koşullarını aşmasını önlemeye yardımcı olduğu gibi güvenlik ve sağlık kontrollerinide kullanılmasına olanak tanıyor. vCenter Server üzerinden kritik kapasite koşullarını aşmasını önlemeye yardımcı olması oldukça güzel bir özellik. Çünkü yukarıda belirtmiş olduğum gibi ESXi host’un down olması durumunda gerekli olan rebuild işlemlerinde kullanılacak kapasiteyi hesaplaması önemli. Manuel olarak hesaplamak isteseniz farklı parametreleri toplamanız gerekir.
Bu özelliğin default olarak devre dışı geldiğini tekrar belirtmek isterim. Eğer free kapasitesiniz yeterli seviyede ise, yani %90 kullanım oranı bulunmuyor ise bu özellikleri aktif hale getirebilirsiniz.
Umarım faydalı olmuştur.
İyi çalışmalar.

In this article we will be looking at how you can enable file service in a vSAN Storage cluster configured in a VMware environment. The vSAN File Service allows a vSphere admin to provision a file share from their vSAN cluster. The file share created can be accessed using NFS protocol. Before you start the configuration you need few items already configured: Setup Pre-requisites A Working VMware vSphere implementation: Setup ESXi hosts and deploying vCenter Server Appliance. Configured and working DNS resolution for all ESXi hosts and vCenter Appliance Static IP address, subnet masks and gateway for file servers DNS name for each IP address or allow the system to do a reverse DNS lookup. The design implementation of the File Service is as captured in the diagram below. Enable NFS File Service in a VMware vSAN Storage Cluster The vSAN File services is supported on DVS version 6.6.0 or higher. You need to create a dedicated port group for vSAN File Service in the DVS. Click on the Cluster name you created in vCenter. The go to Configure > vSAN > Services. Click “ENABLE” under the File Service section. Review requirements in the Introduction page and hit Next if the checklist is satisfied. In the File service agent page there are two options to choose from for downloading the OVF files. Automatic approach: This is the default option which lets the system search and download the OVF. Manual approach: This option allows you to browse and select an OVF that is already available on your local system. Using Manual approach If you don’t have internet connectivity from your VMware Infrastructure you’ll need to have the following files for deployment: VMware-vSAN-File-Services-Appliance-x.x.x.x-x_OVF10.mf VMware-vSAN-File-Services-Appliance-x.x.x.x-x-x_OVF10.cert VMware-vSAN-File-Services-Appliance-x.x.x.x-x-x-system.vmdk VMware-vSAN-File-Services-Appliance-x.x.x.x-x-cloud-components.vmdk VMware-vSAN-File-Services-Appliance-x.x.x.x-x-log.vmdk VMware-vSAN-File-Services-Appliance-x.x.x.x-x_OVF10.ovf Here is the list of the files I downloaded and I’ll be using Manual approach. For my installation I’ll choose Manual approach deployment method. Select all the files and hit Open. Confirm all the files were selected for use during deployment. Set File service domain name. DNS Servers and DNS suffixes. Select network to be used by file service, subnet mask and the network’s gateway. Provide IP addresses which should match the number of hosts in the cluster for best operation. Make sure the DNS names are configured in your DNS server. Confirm configuration details then click “Finish“. If the installation is successful the file service should show as enabled. In our next article we will look at how you can use vSAN NFS file service. Stay connected for updates.

#Vmware quickboot flag metadata vib check drivers#
#Vmware quickboot flag metadata vib check update#
Then go to Admin view > Manage > Settings > Host/Cluster settings > Edit.
#Vmware quickboot flag metadata vib check update#
Launch the vSphere Web Client (Flash), select your vCenter, and go to Update Manager. It seems this is one last part of the UI that needs to transition to the modern HTML5 web-based interface. Where do you enable Quick Boot? ^įor now, the only way to enable Quick Boot is to use the Flash-based vSphere Web Client. Even if your hardware is compatible with Quick Boot, the server might "freeze" with the error message "LoadESX in progress" during the boot process. If you have an unsupported configuration, you might have problems. When using a VMware virtual storage area network (vSAN), it's imperative to follow the hardware compatibility list (HCL) to ensure you have a supported firmware/driver combination. esxupdate: imageprofile: INFO: Adding VIB virtuallyGhettobootbankghettoVCB1.0.0-0.0.0 to ImageProfile HP-ESXi-5.5.0-Update2-iso-5.77. The idea from VMware is great, and it can make you save a lot of time when patching VMware infrastructures because many servers can spend significant time during POST. Quick Boot is disabled in the Update Manager-you can easily check this in the UI (for now through the Flash-based web client only).
#Vmware quickboot flag metadata vib check drivers#
No other non-certified drivers loaded on your host.
No vmklinux drivers loaded on your host.
This cmdlet initializes a PowerShell runspace with a PowerCLI execution context retrieved from another PowerShell runspace. Using Quick Boot is supported with a limited set of hardware platforms, drivers, and is not supported on ESXi hosts that use TPM or passthru devices. This cmdlet retrieves the VMware PowerCLI execution context which you can use to simplify the use of PowerCLI in PowerShell runspaces. Passthrough devices: Another constraint is you can't use Quick Boot with any passthrough devices configured for VMs on your host. The Quick Boot of ESXi hosts is an option that allows Update Manager to reduce the time a host remediation takes by skipping the physical reboot of the host. The VMware vRealize Suite Lifecycle Manager automates the LCM of the vRealize Suite. Here is an example of using the remote vihostupdate utility for an ESXi host, you will need to specify the. The patch bundle needs to be uploaded to ESX host using scp or winSCP and then specifying the full path on the command-line: esxupdate bundleESX400-200907001.zip update. Update standalone ESXi hosts using images. Here is an example of using esxupdate on a classic ESX host. Run vCenter Server interoperability reports D. Host is not configured to use a Trusted Platform Module (TPM): You cannot have a TPM and Quick Boot active at the same time. Upgrade VMware Tools and virtual machine hardware C. Perhaps a future BIOS upgrade from your hardware manufacturer will allow Quick Boot, but nothing is certain. In such a case, there is nothing you can do about it. Host platform is unsupported: One of the first constraints is there's no support for a host platform. My hardware is not compatible with VMware Quick Boot What are the constraints and requirements for Quick Boot? ^

vSphere Mobile Client App
Mobile and other handheld devices are becoming a part of our life by helping us keep up with every possible thing, may it be our health, our social life, or our work. vSphere Client product team wanted to enable admins to keep an eye on their datacenters using these handheld devices.
We are happy to announce that vSphere Mobile Client fling is released to help you monitor your datacenters and take some quick actions to continue running your workloads without any disruption. This lightweight app is available for download for both Android and iOS devices. This app is built using the same vSphere Client (HTML5) APIs, and is compliant with Clarity theme, thus maintaining the consistent data and experience across different vSphere management platforms. Released as a fling since the start of 2019, this app has all the modern mobile app features like Bio-metric authentication, optimized for the touch interface, and offline notification capabilities (more about this later).
Tumblr media
The complete list of VMware Mobile Apps This list is limited to the applications that have VMware (and AirWatch) as developer or company in its descriptions. I know there are much more applications that you can use to manage your VMware infrastructure. Krishnamurti said VMware hopes to have the first phones with the VMware Mobile Virtualization Platform appear by late 2009 or early 2010. Top Picks In Shopping Shopping 5 Peloton bike alternatives.

Vmware Tools Device Drivers
vSphere Mobile Client is built keeping monitoring in mind. You can monitor the resource utilization by VMs, Hosts, Clusters, etc., for the same granular metrics as that of vSphere Client (HTML5). You can also monitor the status of tasks, events, or alarms in your environment. There are only a limited set of operations supported in the app to allow you to mitigate any issues you would notice while you monitor. Ex: a host is running out of resources in a DRS enabled cluster and you want to put a host into maintenance mode so DRS can vMotion your application causing zero downtime or you want to take a snapshot of a VM or power reset a VM for a quick fix or have a quick peek at the VM’s remote console. You cannot perform any advanced operations like configuring a cluster or performing manual vMotions thus reducing the risk of “fat fingering” mistakes.
Another cool feature supported by vSphere Mobile Client is offline monitoring of long-running tasks. Let’s assume you are putting a host into maintenance mode which will trigger a bunch of vMotion operations that could take a lot of time to complete. Wouldn’t it be nice to send a notification to your phone when the task completes, so you can open your laptop only if there are any failures? You could achieve this by configuring a notification appliance that monitors these long-running tasks and sends push notifications to your phone app on task completion.
To use the vSphere Mobile Client app, all you need is a VPN connectivity from your phone app to a vCenter server in your datacenter. If your enterprise uses any form of Mobile Device Management (MDM) software, then you can connect using the built-in VPN in the MDM. Since it’s release in 2019 we have seen a significant increase in adoption and usage of the app across the geography. Some of the future capabilities we are considering bringing in the app are: the ability to manage multiple linked vCenter servers including VMware Cloud on AWS, integration between vSAN monitoring app, customizable notifications, vSphere Skyline health integrations, and browser to mobile handoff capabilities.
Before we want to make vSphere Mobile client app as an officially supported product, we want to get feedback from you. Could you use the app and share the feedback using the in-app feedback capability? Let us know what other features support would make you use this app to monitor your production environment. You can leave general feedback comments in the Fling’s comments section or in the device App stores.
Enjoy the app and let us know what you think about it!

What happened to vSphere Mobile Watchlist?!
There used to be a mobile client to manage vSphere environment called vSphere Mobile Watchlist which was built a long time ago. Since this app was heavyweight, was not built to reuse the vSphere Client APIs, it was very expensive for us to enhance it to give a consistent experience. Rather we rebuilt the brand new lightweight vSphere Mobile client app. vSphere Watchlist is no longer supported/maintained.

Next-gen Dell PowerEdge Servers Upgrade IT
Tumblr media
Dell PowerEdge:
Organizations that switch to new server technology must carefully weigh the advantages and disadvantages of investing in new infrastructure, including hardware, software, and the operating environment. Think about the performance improvements a data center would see with this new or updated gear and software. Organizations will benefit from the most recent security protection, system management tools, processing speed improvements, decreased downtime, and quicker results in addition to increased raw performance. A modernized infrastructure will also increase scalability to smoothly accommodate future growth and boost cluster performance per watt.
All of this suggests that modernizing your hardware, software, and operating system may enhance your data center’s overall performance. However, it can be difficult to align all three aspects at once because earlier choices might impede development.
Express Storage Architecture (ESA)-based vSAN 8.0 is an improved ReadyNode infrastructure offering from Dell, Intel, and VMware. Improved performance and efficiency are provided by this release to cater to the changing business needs of clients.
Customers who use Dell’s PowerEdge R760 server can take advantage of vSAN 8.0, but they must choose between upgrading to the new ESA ReadyNode architecture or staying with the current vSAN Original Storage Architecture (OSA) Ready Node. x86 servers that have been pre-configured, examined, and approved by Dell and VMware are known as vSAN ESA ReadyNodes. Every vSAN ESA ReadyNode is ideally configured with the necessary amount of CPU, memory, network IO, and storage NVMe devices for vSAN ESA or OSA. Dell has more than 250 configurations in total to meet all customer needs, raising the questions of which one to pick and how to migrate.

New Post has been published on https://www.tayfundeger.com/vsan-disk-balance.html
vSAN Disk Balance
Merhaba,
vSAN Disk Balance isimli bu yazımda sizlere vSAN ortamında karşılaştığımız Disk Balance uyarısı hakkında detaylı bilgi vereceğim. Daha önce vSAN Automatic Rebalance ile ilgili bir yazı yazmıştım. Bu yazıma aşağıdaki linkten ulaşabilirsiniz.
VSAN Automatic Rebalance
vSAN ortamı kullanıyorsanız, maintenance veya ESXi host’un down olması gibi durumlardan sonra, Cluster Summary’de aşağıdaki gibi bir uyarı ile karşılaşabilirsiniz.
Warning: Virtual SAN Disk Balance
vSAN ortamında bulunan bir ESXi host’u Evacuate all data seçeneği ile maintenance’a almanız durumunda vSAN node’u üzerindeki datalar farklı hostlara taşınacağı için node’lar üzerinde disklerde eşit yükler bulunmaz. Tabiki bu senaryoyu daha fazla genişletebilirsiniz. Zaten makalemin ilerleyen bölümlerinde buna yer vereceğim.
vSAN Cluster’ında herhangi bir ESXi host üzerindeki disk/disk grupları %80 dolabilir. Böyle bir durumda vSAN, doluluk yaşanan disk veya disk grubunda bu alanı %80’in altına düşene kadar cluster’i otomatik olarak dengeler. Burada %80 diye belirtiyorum ancak bu değer Rebalance işlemlerini manuel veya automatic yapmasanız bile %80 eşiğine geldiğinde otomatik olarak yapılır. Ayrıca isterseniz bu değeri değiştirebilirsiniz. Bu işlem yapılırken performans sorunları yaşayabilirsiniz. Performans sorunları derken, vSAN cluster’ınızda virtual machine çalışamayacak düzeyde bir performans sorunundan bahsetmiyorum 🙂 Disk rebalance işlemi, vSAN cluster’ınızın I/O performansını etkileyebilir. Bu performans etkisinden kaçınmak için automatic rebalance işlemini, altyapının yoğun olarak kullanılmadığı gün/saatlerde aktif edebilirsiniz.
vSAN Disk Balance
Daha önce yukarıda belirtmiş olduğum makale içerisinde de belirtmiştim ancak tekrar belirtmek istiyorum. Aşağıda belirteceğim işlemler disk kapasitelerinin %80 ‘e ulaşmasına ve rebalance işleminin başlamasına sebep olabilir.
Cluster’da donanım arızası olabilir.
vSAN ESXi host’ları Evacuate all data seçeneği seçilerek maintenance mode’a alınır.
FTT=0 olarak konfigure edilmiş bir vSAN cluster’ınız var ve Ensure data accessibility modu ile maintenance mode’a alınır.
Yukarıdaki durumların oluşması durumunda rebalance işlemi başlar.
Rebalance işlemini 2 farklı şekilde yapabilirsiniz. Ancak burada kullanmış olduğunuz versiyon önemli rol oynuyor.
Proactive Rebalance: vSAN 6.7 U2 ve daha eski bir sürüm kullanıyorsanız, Disk Balance uyarısını gördüğünüzde vSAN Health bölümüne giriş yapabilir ve buradan manuel olarak Proactive Rebalance işlemini gerçekleştirebilirsiniz.
Automatic Rebalance: vSAN 6.7 U3 veya daha yeni bir sürüm kullanıyorsanız, Disk balance uyarısını gördüğünüzde eğer Automatic Rebalance özelliği aktif durumda ise bu işlem otomatik olarak gerçekleştirilir.
vSAN Disk Balance
Öncelikle vSAN 6.7 U2 ve daha eski bir sürüm kullanıyorsanız Proactive Rebalance kullanmanız gerekiyor. Bunun için Monitor > vSAN > Health bölümüne giriş yapmanız gerekiyor. Bu bölüme giriş yaptığınızda karşınıza zaten vSAN Disk Balance warning’i ile karşılaşacaksınız. Bu bölümde Proactive Rebalance Disks butonuna bastığınızda işlem başlayacaktır.
ilk 30 dakika boyunca herhangi bir ilerleme göremeyebilirsiniz. Bunun nedeni, VSAN’ın herhangi bir nesneyi hareket ettirmeden önce dengesizliğin devam ettiğinden emin olmak için beklemek istemesidir. Sonuçta, yeniden dengeleme görevi nesneleri diskler/node’lar arasında taşımaktır. Bu işlem network üzerinden veri kopyalama işlemi yaptığı için, data’nın büyüklüğüne göre bant genişliği ve zaman gerektirir. Bu işlem 24 saat sürebilmektedir. 24 saat sonrasında otomatik durdurulacaktır. Ancak tekrar belirtmek istiyorum, bu işlemi minimum iş yükü olduğunda yapmanız tavsiye ediliyor.
vSAN 6.7 Update 3 ve sonraki versiyonları kullanıyorsanız artık Proactive Rebalance işlemini yapmanıza gerek bulunmuyor. Ancak Automatic Rebalance ‘i öncelikle aktif etmeniz gerekiyor. Bunun için isterseniz yukarıdaki ekrandaki gibi Configure Automatic Rebalance butonuna basabilirsiniz. İsterseniz de Cluster’ı seçtikten sonra Configure > vSAN > Services > Advanced options bölümüne girebilirsiniz.
Advanced Options bölümüne girdiğinizde Automatic Rebalance butonunu göreceksiniz. Default olarak bu seçenek disable durumda gelir. Automatic Rebalance ‘i aktif duruma getirdiğinizde hemen altında Rebalance Thereshold yüzdesi belirtebilirsiniz. Burada belirteceğiniz değerin üzerine disk üzerindeki veri miktarı çıktığında otomatik olarak rebalance işlemi başlar. Siz bu değeri istediğiniz gibi değiştirebilirsiniz.
Önemli: Rebalancing Thereshold değerini default olan %30 değerinde tutun. Bu değerin düşürülmesi, rebalance trafiğinin miktarını artırabilir ve hiçbir işlevsel fayda olmaksızın gereksiz yeniden rebalance’a neden olabilir.
Ancak şunu belirtmek istiyorum. Yukarıda da belirtmiştim aslında. Eğer diskler üzerindeki doluluk %80’e ulaştığında Automatic Rebalance aktif olmasa bile otomatik olarak rebalance işlemine başlanır. Yani %80 üzerine disk doluluğu çıktığında siz hiç bir işlem yapmasanızda, automatic rebalance aktif olmasada arka planda rebalance yapılır.
Rebalance işlemleri sadece disk grupları üzerinde yapılır. Yani, automatic rebalance’i cluster üzerinden aktif ediyorsunuz ancak sadece belirtilen eşik değerleri üzerinde bulunan ESXi hostlar üzerinde bu işlem gerçekleştirilir. Yani komple cluster üzerindeki tüm ESXi host’lar üzerinde bu işlem yapılmaz. Diskler veya disk grupları üzerindeki veriyi sadece ihtiyacı kadar hareket ettirecektir.
vSAN Cluster’ınızda automatic rebalance özelliğini etkinleştirmeniz önerilir. Özellik 6.7 U3’e eklendiğinde, VMware bu özelliği müşteri ortamlarına yavaş yavaş tanıtmak istedi ve vSAN 7’de bu şekilde kalmaya devam etti.
Daha öncede belirttiğim gibi, cluster üzerinde automatic rebalance’i geçici olarak devre dışı bırakmak isteyebileceğiniz birkaç nadir durum olabilir. Kısa bir süre içinde mevcut bir cluster’a çok sayıda ek ESXi host eklemek, bu olasılıklardan biri ve belki de testler için kullanılan nested vSAN ortamları olabilir. Ancak bunun dışında çoğu durumda, automatic rebalance etkinleştirilmelidir.
Umarım faydalı olmuştur.
İyi çalışmalar.

VMware vSAN Resilience
By Curtis Brown
VMware vSAN™ is VMware’s hyper-converged storage solution.  It has quite a few different methods of providing resilience for the data hosted in it, but these all require some careful consideration when designing the cluster.  In this blog I take a look at the configuration options and the design repercussions.
Storage Policy with respect to Resilience
All the approaches are ultimately defined by the VMware vSphere Storage Policy definitions. These policies are defined in VMware vCenter and are applied to objects (usually VMs, but can be individual disks, VM configuration files), subject to the compatibility with the underlying vSAN cluster.  However, there are limitations.
The most basic, default policy is RAID-1 configured with a Failures to Tolerate (FTT) of 1 – classic mirroring.  In vSAN, this means a complete mirror of the given object, creating two components. In addition, there’s a smaller Witness component.  This means we must have a minimum of three nodes in a cluster (though four would be recommended for maintenance and failover).  We can up the ante here by increasing FTT value, but while resilience improves there is an obvious impact on capacity.
Tumblr media
We can also look at using Erasure Coding to give us RAID-5/6 protection.  This takes our object and breaks it out into components, with the data striped across them for resilience.  From a configuration perspective, all that separates them is that the FTT value of 1 means RAID-5, while FTT of 2 is RAID-6.  However, this does impact the number of components created.  In RAID-5, for any object, we have three components created with data striped with a parity bit across them.  So rather than the 200% footprint as with RAID-1, we only need 133% instead and get the same resilience, though at a performance cost. RAID-6 requires a fourth object and an extra parity bit, so the footprint is in between at 150%.  In either case, we still have a witness component too, so RAID-5 needs a minimum of 4 hosts (5 recommended) and RAID-6 needs 5 hosts (6 recommended).
Tumblr media
Fault Domains
Of course, physically our clustered hosts are usually installed in one or more physical racks. Ideally, we’d spread the nodes across racks to mitigate the loss of a rack.  vSAN provides Fault Domain functionality to provide an awareness of these physical boundaries.
Consider a Fault Domain as a grouping of hosts within the cluster to represent a boundary of resilience to ensure that vSAN objects subject to a Storage Policy are deployed across the domains, so providing resilience to a loss of a domain (i.e. the loss of a rack) outage.
However, it’s not quite as easy as slinging your hosts into a pair of racks and setting up two zones. As stated above, even RAID-1 requires three hosts due to three objects.  This has a knock-on impact when defining Fault Domains too. ��For RAID-1 based policies, the number of Fault Domains can be represented by the formula (2 x FTT)+1, while RAID 5/6 is (2 x FTT)+2. Therefore, RAID-1 at a minimum requires three domains while RAID-6 would require at least six domains (6 = (2 x 2)+2).
Tumblr media
This obviously has limitations as to how useful the feature is when mapped to physical racks – Are you going to spread a small 6-node cluster across six racks to achieve six domains?  Or, perhaps across two racks and configure 6 zones, but you could lose three in the event of a rack failure so negating the effort of configuring Fault Domains in the first place.
We now see that the scale of the cluster and physical placement are important factors when deciding whether to use Fault Domains.
Stretch Clusters
This approach is designed to be used across different locations (latency permitting) and largely builds on the concept of Fault Domains.  Here, we have two defined Fault Domains (a Preferred and Secondary).  Alongside these, we also deploy a Witness appliance in a third location – this serves as a third Fault Domain.  We also break out the Failures to Tolerate into two values.
Primary Failures to Tolerate – Refers to Site level failure and can be a value of zero (no resilience, all data resides on either the Preferred or Secondary site) or 1, where the data is replicated between the two domains in the manner of RAID-1.
Secondary Failures to Tolerate – Analogous to FTT in a single site, this is the resilient behaviour within the single site and so can be configured as RAID-1 or RAID-5/6 with various FTT values.
The PFTT value effectively sits above the SFTT value, resulting in the following:
Tumblr media
Logically speaking, for a given object, such as a VMDK, the Primary value essentially pushes a RAID-1 mirror across each site, with a Witness component in the appliance.  The Secondary element in concert with the RAID setting defines the policy within a site, here a straightforward RAID-1 mirror.
For the numbers of hosts, we therefore need to adhere to the needs of the local policy (be that RAID-1, 5 or 6) and double-up for the second site.
As this resides in a stretch vSphere cluster, we also need to build in some stickiness with respect to compute – so designing DRS and HA accordingly to match the preferred sites.
Closing Thoughts…
When embarking on a vSphere with vSAN design, one should consider not just the compute factors when deciding the number of hosts, but what level of storage protection will be required for the VMs.  In fact, by using the protection as a starting point (i.e. ‘We want RAID-6, so a minimum of five hosts is recommended’), the RAM and CPU can be defined above that – whether scaling upwards (five big hosts) or outwards (more, smaller hosts).  Even the physical rack design might be a determining factor – whether you can spread across racks or not.
