VMware vSAN Pros and Cons

VMware vSAN Pros

CEO / Cloud Evangelist at Comdivision Consulting GmbH
We can also create test cases. We can even throttle down performance or release more performance. So, we can run more precise test scenarios.
When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes

It is very easy to set up and very easy to use. It is very useful.

If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now.

The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering.

VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products.

VMware vSAN Cons

CEO / Cloud Evangelist at Comdivision Consulting GmbH
When we talk about improvements for vSAN, there is some way to go from a at least stability perspective. Adding all these new features is nice, but we are now at the level that most of the features you need in production are there.
Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would uncoupled even more.

If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much.

I would like to see better integration between the cloud and our VMware virtual environment. We only have one virtual environment, which is VMware vSAN. Right now, there is little interoperability with the cloud solution at the moment.

The only negative point relates to the licensing. If you want multiple, different servers, it costs money, but you have all the capacity for vSAN. You do not reach the data, but the processor arrays and the current architecture.

There's a lot that can be done to segregate. That may be available now in vSAN 7, I suppose, however, the deduplication and compression can be segregated.

Hardware load balancing is available on the enterprise version of the solution, however, it's extremely expensive and therefore out of our budget.

The ability to access SAN environments with fiber channels (or even NVMe) would be a good addition.

I would like to see more support for applications. I think currently it only supports applications between two vSAN clusters.
