VMware vSAN Review

You can set up storage policies and assign them at the disk level.


What is most valuable?

  • Allows for very easy administration
  • You don't have LUNs to set up and assign
  • The ability to set up storage policies and assign them at the disk level
  • Allows for different setups for different workload requirements

How has it helped my organization?

  • Allows for the expansion of our public library patron computer environment into a three-node VMware cluster using commodity servers
  • Eliminates the need for expensive disk arrays and controllers
  • Provides greater reliability and performance

For how long have I used the solution?

We have been using vSAN in one environment for about eight months and in another environment for about four months.

What was my experience with deployment of the solution?

The only issue I encountered during deployment was with the hardware and not with vSAN itself.

The disks in the new servers were installed at the factory as RAID disks. I had to mark them as non-RAID disks so that vSAN would be able to see them correctly in order to add them to disk groups.

What do I think about the stability of the solution?

There have been no issues with stability.

What do I think about the scalability of the solution?

We have had no issues with scalability.

How is customer service and technical support?

Fortunately, I have not had to contact support for any issues with my implementations.

Which solutions did we use previously?

We chose VMware vSAN for these reasons:

  • It is part of the ESXi kernel. This allows for the product to be very fast with little overhead.
  • It is included in the Enterprise Plus version of ESXi. Compared with competing products, it provides great cost savings.

We have a Nutanix environment running in production as well.

How was the initial setup?

The initial setup was straightforward as was learning the vSAN environment.

The complexity comes in setting up and managing the storage policies. These can be simple or complex depending on the environment.

When using VMware Horizon View, there are several storage policies that are auto-created and managed. Creating and managing your own policies and rule sets depend on your needs and workloads.

What was our ROI?

VMware vSAN is included in the enterprise plus level of software that we purchased. Our cost savings were due to buying commodity server hardware with local hard drives instead of investing in large SAN hardware.
