Vsphere5.1 - Introducing Virtual Machine Compatibility

With each new Vsphere release, Vmware continues to enhance virtual machines features and capabilities to help track the features and capabilities associated with a given virtual machine,VMware has traditionally used a virtual machine hardware version number.

A list of virtual machine hardware version numbers associated with each vSphere release is shown in the following table:


Using a virtual machine's hardware version number, administrators can readily identify each virutal machine's feature set and capabilities.

feature set and capabilities. Historically, it has been considered a good practice that each time an upgrade is made to a vSphere infrastructure (VMware VCenter Server (vCenter Server) and associated Vsphere hosts), the Virtual machine hardware version for each virtual machine is also upgraded.

This would ensure that each virtual machine had the ability to fully benefit from the latest updates and newest features.However,over time serveral challenges to this approach have been identified.


1. Upgrading a virtual machiine's hardware version requires powering off the virtual machine, which requires downtime. With many virtual machines now hosting mission-critical workloads,it can be difficult to shedule downtime.

2. As the size of the virtual infrastructure grows, trying to keep a large number of virutal machiens running at a common virtual machine hardware version proves difficult if not impractical.

3. In many cases, a virtual machine's requirements are fully satisfied with the odler virtual hardware version so a virtual machine upgrade might yield little or no benefit.


With these challenges in mind, and to help simplify virtual infrastructure upgrades, VMware formally extended the virtual machine compatibility matirix in vSphere 5.0. The extended support matrix enables virtual machines running older virtual hardware versions to run fully supported on newer versions of vSphere. The following table show the extended virtual machine hardware version support matrix:


vSphere 5.1 - Extended Guest OS and CPU Support

Along with security, auditing and monitoring updates, and the enhanced vMotion capabilities,vSphere 5.1 adds support for the latest guest operation systems and SPUs. Vsphere 5.1 introduces support for Microsoft Windows 8 both server and desktop editions, along with support for the latest AMD and Intel CPUs, including the AMD " Piledriver" series and the Intel " lvy Bridge" and "sandy Bridge" series.


vSphere 5.1 - vMotion Enhancements

Enhancements to VMotion in Vsphere 5.1 provide a new level of ease and flexibility for live virtual machine migrations. Vsphere 5.1 now enables users to combine VMotion and VMware vSphere storage vMotion (storage vMotion) into one operation.The combined migration copies both the virtual machine memory its and disk over the network to the destination host.In smaller environments, the ability to simultaneously migrate both memory and storage enables virtual machines to be migrated between hosts that do not have shared storage.

In larger environments ,this capability enables virtual machines to be migrated between clusters that do not have a common set of datastores.


What’s New in VMware vSphere 5.1

VMware vSphere 5.1 brings many new capabilities that extend the benefits of vSphere 5.0, including a number  of new, storage-related features. Many of these enable VMware flagship products such as VMware vCloud Director and VMware View. vSphere 5.1 storage features and enhancements also bring additional scalability, performance and troubleshooting capabilities. This paper focuses on the storage-specific features and enhancements that are available in vSphere 5.1.

The following topics will be discussed in this paper:
  • VMware vSphere VMFS-5 file-sharing enhancements
  • Space-efficient sparse virtual disks
  • All paths down (APD) condition–handling enhancements
  • Storage protocol supportability improvements

RAID 5 and 6 support for VMware VSA



Yesterday VMware announced that it will be supporting RAID 5 and 6 with their Virtual Storage Appliance (VSA).

With the release of vSphere 5, VMware also released their VSA, a shared storage solution for the SMB market. VMware VSA uses the local storage in each ESXi server, presents it to the VSA appliance which in turn serves it back to the ESXi servers as shared storage.  Each ESXi server needs to run a VSA appliance, and each will contain a replica of the other’s storage.
Until now the VMware VSA only supported RAID 10, which resulted in very low storage utilization. Running VMware VSA with mirroring between two ESXi server, meant that you could only use 25% of your actual storage capacity.

Now with the added support for RAID 5 and 6, VMware VSA offers a greater storage utilization rate.

A few examples:

RAID 10

In order to be supported, VMware required your local storage to be configured as RAID 10.  In a two node configuration, the VSA’s are in a RAID 1 for HA purposes. Using six 600GB disks in each ESXi server, in a RAID 10 configuration, will result in 1,8TB usable space per ESXi server (50%). Because the VSA’s use mirroring each VSA reserves 50% of the storage for the other VSA’s replica. This leaves us with 900GB of useable space on each ESXi server. The storage utilization in this configuration is 25%.

RAID 6

Now with a newly supported RAID 6 configuration, in a two node configuration with the same six 600GB disks. This results in 2.4TB usable space per ESXi server (67%). Because of the 50% reservation for the other VSA’s replica, this leaves us with 1.2TB of useable space on each ESXi server and a storage utilization of 33%.

RAID 5

In a RAID 5 configuration, in a two node configuration with the same six 600GB disks, the utilization increases even further. A RAID 5 configuration results in 3TB usable space per ESXi server (84%) and 1.5TB of useable space on each ESXi server and a storage utilization of 42%.

So, now the VMware VSA is even more compelling for the SMB market because of the increased storage utilization. For those that are looking to virtualize to achieve business continuity benefits and don’t have the resources/capacity to deal with a SAN or NAS, VSA is a great choice. If you have evolving storage needs and need a shared storage solution to provide high performance and scalability, you may need to look for a SAN or NAS solution.
