VMware vSAN Review
We can set up storage policies and assign them at the disk level.


Valuable Features:

I find that vSAN allows for very easy administration. The fact that you don't have LUNs to set up and assign is great. The ability to set up storage policies and assign them at the disk level is also a great part of this product. You can allow for different setups for different workload requirements.

Improvements to My Organization:

vSAN allowed for the expansion of our Public Library Patron computer environment into a three-node VMware cluster using commodity servers. This eliminated the need for expensive disk arrays and controllers while providing greater reliability and performance.

Use of Solution:

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

Deployment Issues:

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 for addition to disk groups.

Stability Issues:

We have had no issues with stability.

Technical Support:

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

Previous Solutions:

We have a Nutanix environment running in production as well. We chose VMware vSAN for several reasons. First, the vSAN solution is part of the ESXi kernel. This allows for the product to be very fast with little overhead. Secondly, vSAN is included in the Enterprise Plus version of ESXi which, compared to competing products, provides a great cost savings.

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.

ROI:

VMware vSAN is included in the Enterprise Plus level of software that we purchase. Our cost savings is in buying commodity server hardware with local hard drives instead of investing in large SAN hardware.

Disclosure: I am a real user, and this review is based on my own experience and opinions.
