It's not for anyone.

VMware vSAN is one of our storage tools and we use it for tier 2 storage. It is great in the scalability but not that great for high performance.

It is a great alternative for a homogenous environment with no high IOPS utilisation.

Sadly, it's too expensive.
  • Easy to implement
  • Scalability
  • Easy to manage
  • Support is very slow
  • Expensive
  • More expensive if you need to use advanced features
It dependents on what your needs are. I don't recommend it for high performance. But if you need a reliable easy SAN it's a great idea to use it.

vSAN use in an R&D lab

Departmentally for R&D to investigate how our product line interacts within its framework. It solves multiple business problems including data integrity, business continuity for the department, and hyper-convergence for speeds and workloads. We have found that the platform will significantly accelerate workloads with limited issues. We are always seeking solutions that provide optimal data throughput with non-hardware redundancy.
  • Data integrity in an all-flash environment is very strong. Once it is up and running in a "raid 6" type format it will stay running without issues for a long time
  • Data flow. VMs sometimes require a lot of tweaking and tuning to get optimal performance but this is to be expected. We found the performance to be exceptional.
  • Portability of the VMs was also an unexpected surprise. The ability to migrate the VMs across datacenters was appreciated.
  • It would be nice to have fabric-based storage acceptance to disaggregate storage and expand beyond the node concept. The assumption that increased storage needs require increased compute or ram is simply not true.
  • The licensing costs are high but you do get what you pay for.
High IO is excellent, but I was surprised by the performance in high write transactional testing. It performed well above my expectations. It performs well in environments with focused workloads and we recommend that each workload be its own cluster size-dependent of course. Again, assuming the workload needs the performance, you would be hard-pressed to find a better solution if you already have VMware in your environment.

vSAN pairs great with branch and remote offices

vSAN is deployed in our branch locations with small vSphere clusters. It allows us to run storage within the same ESXi hosts without an external array required for shared storage. It has allowed us to use the existing drive bays in our ESXi hosts to create a software-defined SAN.
  • Creates a software-defined SAN in a hyper-converged form factor.
  • It's simple to deploy and configure.
  • It integrates into existing vSphere tools and consoles, decreasing the learning curve.
  • It allows us external access to storage with iSCSI connectivity.
  • An expanded HCL could assist with more compatibility, becoming less of a problem as new versions are released.
vSAN works very well in the branch or remote office use case. It is also well suited for smaller data center deployments.

VMware vSAN - hyper-convergence versus dedicated storage is a great alternative

We started using VMware ESX in a typical dedicated host and dedicated storage model using Dell hosts and Nimble Storage arrays several years ago. We figured out a few years back that a hyper-converged model seemed to make more sense for lower budget SMB users like us. Researching hyper-convergence led us to VMware vSAN. We currently are using vSAN in four datacenters and in several other locations leveraging their vSAN Robo product across our entire organization. vSAN seems to give us more flexibility in upgrades to our environment related to storage, compute, and RAM.
  • We are using VMware vSAN in our primary datacenters using relative in-expensive flash storage drives. This allowed us to really increase our storage performance over dedicated storage at a much lower overall price.
  • By buying ESX hosts that were only partially loaded with drives, we have great flexibility in adding additional capacity without much effort.
  • The volume management versus dedicated storage was greatly simplified. Each ESX cluster acts as one single large volume rather than having lots of carved up volumes all over the place as we did with dedicated storage.
  • Management is integrated directly into the vSphere client rather than having to go elsewhere.
  • We were a fairly early adopter of VMware vSAN and as such experienced several growing pains.
  • We experienced a few bugs that took a few software versions upgrades to go mostly away.
  • The biggest issue we had overall was with host drivers. Even with vSAN ready node compatible hosts, you have to be very careful that the drivers for NIC and RAID controllers are right.
For an SMB, vSAN and other hyper-converged products seem to provide a cost-benefit especially as it relates to future growth and reduced management. VMware vSAN is not, however, a simple-to-understand product. It can be easy to set up and deploy with the proper understanding, but there are serious complexities that need to be understood and mitigated for you to be successful and very happy with its long term care and operation.

Admins agree that vSAN is great!

Our vSAN deployment is currently used as the main hyper-converged infrastructure solution at our main headquarters. It houses the bulk of our production virtual servers including a line of business and critical systems. We do not currently use it for SQL due to excessive licensing costs from Microsoft, but that is not VMware's fault. We do not use VDI but do host virtualized applications from it through Citrix presentation servers.
  • I have had zero problems with vSAN storage and don't even think about it on a day-to-day basis.
  • It allows me to throw a bunch of JBODs together and make an enterprise grade SAN out of it.
  • Allows a single pane of glass for managing our virtual infrastructure.
  • Original implementation was not bad, but we ran into some issues that could have been avoided.
  • Calculating disk space is funky and can be misleading.
If you're already a VMware shop, vSAN is a no-brainer, especially if you're looking to upgrade storage already. With the improvements in vSAN 6.7, it's really on par with the best storage solutions out there and can be really cost effective. Depending on your budget you can customize your solution to tailor your own needs whether it's a low-cost hybrid solution or an all-flash with NVMe screamer.
