VMware vSAN Review

It integrates with other commonly-used VMware tools, but it lacks deduplication and wastes a lot of mass when striping across multiple nodes and vSphere hosts.


Valuable Features

Simple to set up, manage, and integrate it with tools you’re already familiar (vCenter, vClient) with.

It also gives us a policy-based storage on a per-VM level.

Also if you can apply redundancies to machines, they’re all different.

Improvements to My Organization

  • All built within hypervisor
  • Easily stood up with hardware you already have
  • Truly virtualized storage
  • Get rid of all hardware, and you get a much smaller footprint
  • Nodes can be in different datacenter, and so can stretch cluster

Room for Improvement

  • Good job integrating with vRealize, vCOPS, etc.
  • Needs complete integration with vRealize for GUI for drill down analysis
  • Would be nice to see features like dedupe because it wastes a lot of mass when striping across multiple nodes and vSphere hosts.

Stability Issues

Some difficulty finding compatible hardware, but if you follow the HCL provided by VMware. and make sure you're buying the correct nodes, storage devices, and SSD’s that are all supported, then it’s a stable product. Even if you have problems, it's still only one phonecall.

Scalability Issues

It supports up to 64 nodes so huge scalability.

Customer Service and Technical Support

As a VMware customer for many years, sometimes it takes a few calls, but they have some brilliant people who can solve difficult technical problems.

Initial Setup

  • Setup just a few clicks after hardware all connected, “pretty stupid easy”.
  • Customers can test and validate without going out and buying vSAN ready nodes.

Other Advice

It loses points because it lacks lots of performance and deduplication abilities that competitors have.

Disclosure: My company has a business relationship with this vendor other than being a customer: We're a partner.
