Ben Fathi, the CTO of VMware announced the Virtual Storage Area Network (VSAN) feature in vSphere ESX on March 6, 2014.

VSAN is a storage technology that pools all local disks on multiple servers into one large distributed volume. Caching is done via an SSD drive.

Unfortunately, licensing and pricing details get released at VSAN General Availability around March 10th.

Out of the door, the VSAN will have the following features:

  1. Full support for VMware Horizon / View (no VSAN inside View — yet)
  2. Up to 32 nodes.
  3. Up to 2 million IOPS.
  4. 4.5 PB of space.
  5. 13 VSAN Ready Node configurations at launch using Cisco, IBM, Fujitsu or Dell servers.
  6. Build your own supported.

However, VSAN will also have the following requirements:

  1. At least 1 SSD drive.
  2. Up to 7 mechanical drives.
  3. Cannot use all SSDs or SAN storage.
  4. SSD must be at least 10% of space.
  5. Need ESXi 5.5 Update 1.

VSAN competitors:

  1. EMC’s ScaleIO — can build distributed storage on any OS out there (Windows, Linux plus VMware) and more nodes (per Duncan Epping).
  2. Nutanix — server, storage, VMware in a customized box.
  3. Simplivity — same concept as Nutanix.
  4. Pivot3 — same concept as Nutanix.
  5. Virtual Storage Appliance (VSA) solutions (VMware own VSA, Atlantis, HP Lefthand VSA, etc.).
  6. Regular storage arrays.
  7. Flash only storage arrays (XtremIO, EMC VNX-F, Cisco’s Whiptail/Invicta)

Analysis:

There is a lot of interest in VSAN. The beta had more than 10,000 people sign up. Some VMware partners around the country are preparing solutions already, ready to sell to eager customers.

However, everything depends on how it’s licensed and priced. The price has to be lower than traditional storage and even VSA solutions (except maybe VMware’s VSA). Only then it will make sense for the smaller customer.

Otherwise, especially for lower end Virtual Desktop Infrastructure (VDI), the VSAN is perfect — easy to set up (one checkbox), minimum of only 3 servers, provides enough IOPS with SSD caching. We are planning to use it for VDI.
