VSAN-ExchAs we continue to showcase the value and capabilities of Virtual SAN, I believe it is crucial to provide access to the information VMware’s performance engineering team has gathered around business critical applications and their respective performance benchmarks.

This white paper focuses on Microsoft Exchange Server performance on VMware Virtual SAN. Microsoft Exchange Server is a commonly found email server and is considered a business-critical application by many organizations. Virtualized instances of Exchange Server can be successfully deployed using VMware vSphere 5.5 and it has been shown that Exchange Server performs well in a virtualized environment with shared SAN storage .

With the release of VMware Virtual SAN, the next logical step is to study the performance of Exchange Server on this storage platform. VMware performance testing shows that Microsoft Exchange Server 2010 on Virtual SAN clusters scales well without affecting much user-perceived application latency as more Exchange users are deployed with added VMware Virtual SAN hosts.

Take a look at the white paper and review the results of this study.

VVols-LogoIn case you didn’t get a chance to attend VMworld this past week in San Francisco, there were a lot great sessions delivered on different types of products and technologies. One of my sessions made it into the VMworld top 10 lists “Virtual Volumes Deep Dive”.  The session was well received and it was actually published on YouTube.

Just in case you’re new to Virtual Volumes, here is a brief overview of what it is:

Virtual Volumes is a new virtual machine disk management and integration framework that exposes virtual disks as native storage objects onto storage arrays that enables array-based operations at the virtual disk level.

Virtual Volumes transforms the data plane of SAN/NAS storage systems by aligning storage consumptions and operations with virtual machines. In other words, Virtual Volumes makes SAN/NAS storage systems VM-aware and unlocks the ability to leverage array based data services and storage array capabilities with a VM-centric approach at the granularity of a single virtual disk.

With Virtual Volumes, most of the data operations are offloaded to the storage arrays. New data management operations, and communication mechanism have been implemented to manage required communications between vSphere, storage arrays and the Virtual Volumes.

This new white paper focuses on Microsoft SQL Server workload performance on VMware Virtual SAN. The study was performed with the used of the DVD Store benchmark application utilizing Virtual SAN as the storage solution. The tests performed show that VMware vSphere 5.5 with Virtual SAN is an effective storage platform for transactional database workloads like Microsoft SQL Server.

Oh yeah!!!!!! It’s official, the Virtual SAN Sizing Tool is now live and available to the general public.

All Virtual SAN customers and enthusiasts can easy get sizing ideas and estimations on the amount hardware resources necessary to support a particular Virtual SAN design. All you will need  to do is provide a few virtual machine inputs based on capacity, performance, and availability requirements.

VMware Virtual SAN Sizing Tool

The purpose of this tool is to help determine the hardware specifications for hosts in a Virtual SAN cluster required to run a set of virtual machines defined by a set of input characteristics. These important assumptions should be understood before using this tool:

  • All hosts in the cluster are assumed to have an identical hardware profile, i.e. numbers of hard drives and flash devices, amount of physical RAM, and number of CPU cores
  • All virtual machines are assumed to be identical in storage characteristics, i.e. number of VMDKs, size of VMDKs (assumed identical for all disks), number of snapshots, and virtual memory size
  • All virtual machines are assumed to have the same Virtual SAN policy, i.e. number of failures to tolerate and number of disk stripes per object

The tool is designed so that you can easily vary inputs to see the impact on the sizing output, thus allowing you to iterate manually for more sophisticated analyses.

Feel free to provide feedback and let us know what your thoughts are about the tool and help us improve it.

See you all at VMworld!!!!
