Overall Satisfaction with VMware vSAN

Our current license is the standard ( we previously had an advanced license). Managing an increasingly complex storage infrastructure with proper efficiency and costs is not an easy task, but vSAN has proven remarkably helpful in order to do that. In conjunction with vCenter and vSphere, it has reduced our complexity and costs greatly.

Our vSAN deployment is currently being used as the main infrastructure solution. We use vSAN for virtual desktops, cluster management, and data warehouse support. We use an SSD disk and HD per each ESXi, vSAN uses the SSD for the cache and the HD for data storage. What I especially appreciate is the data deduplication and compression and the raid 5 versus erasure coding, since it enables higher consolidation ratios, reducing costs. (Sadly this feature is only enabled starting at advanced licenses). It holds the majority of our production virtual servers, It really helps us to solve multiple problems such as data integrity, system stability, and has improved hyper-convergence for speeds and workloads.
  • Very strong data integrity.
  • The portability of the VMs.
  • Dataflow is great without a lot of tweaking.
  • The in-place encryption is a strong layer of security and it is great for establishing multi-tenancy trust.
  • Ease of use from vCenter.
  • Great data compression, lowering costs.
  • Expensive, but it's worth it since it actually reduces costs (in addition, whichever vSphere licenses you need).
  • Even though the license prices were a huge investment, this has brought us better performance.
  • VM portability made testing faster.
  • Lower costs of ownership.
Support isn't that great compared to other VMware products and is kinda slow But, I didn't have any issues with it, other than response speed.
Deploying and configuring VSAN is a relatively simple process for people that are already used to working in virtual environments, primarily for those that are familiar with vSphere. The compatibility of those two products is amazing. You shouldn't really encounter any issues and if you do, you surely did something wrong.

Do you think VMware vSAN delivers good value for the price?


Are you happy with VMware vSAN's feature set?


Did VMware vSAN live up to sales and marketing promises?


Did implementation of VMware vSAN go as expected?


Would you buy VMware vSAN again?


It's not that good performance-wise and sadly the cost on each processor quickly scales up. However, it's great for scalability and data integrity, easy to deploy and configure. If you need more power, buy more nodes. It's great for small data centers but I wouldn't personally use it for big ones. vSAN is a good, yet expensive (because of the cost for each processor will quickly add up), option for hyper-converged storage.

The only thing I disliked is that data deduplication and compression and the raid 5 erasure coding are only for licenses equal or higher than advanced.
