VSAN Officially Announced!

Yes the official announcement for VSAN has been made.  I was not able to catch as it was 2am Singapore time.  However you can watch the launch recorded video here.  

You can read about the release notes here. Do note of a known error which some might encounter when enable VSAN without any disk group and after removal the error message remain persistent.  I admit many like myself so not read release notes.
Error Message:
"vsan datastore datastore1 in cluster **** in datacenter **** does not have capacity"

Cormac Hogan has also did a summary of the launched which is pretty lots of supported feature beyond what was release in beta.  E.g. from 8 nodes to 32 nodes and from 120,000 IOPS to 2 Million IOPS.  Vicardo has done upa nice table here on comparison.  David Hill has a very long table of limit for Public Beta here which I made some correction in my table below:

Description	Public Beta	GA
Minimum nodes	3	3
Minimum SSD	1	1
Minimum MD	1	1
Maximum number of disk stripes	12	12
Maximum number of failures tolerated	3	3
No of VSAN hosts per Cluster	8	32
Max number of IOPS	120,000	2,000,000
Max number of Parallel vMotion per VSAN cluster	8	8
Max number of Parallel SvMotion per VSAN cluster	2	2
Max number of VMs per host	100	100
Max number of VMs per (evenly distributed) VSAN cluster	800	3200 (2048 protected by HA)*
Max number of disk groups per host	5	5
Max number of hard disks per disk group	7	7
Max VSAN Size	1.1 PB	4.4 PB
Max components per node	3000	3000
Max size per component	255GB	255GB

*Duncan has a post on the HA limit per datastore mentioned of why 2048 VMs are protected here.

Note: You would need vSphere 5.5. Update 1 to use VSAN.

The VSAN sizing guide is also been release here.  During pubic beta the recommend sizing was 1:10 between SSD and MD.  On GA, based VSAN sizing guide, its now 10% of total utilized space.

The Register has also wrote on the launch with its view here.   Though the official GA where it is available for download would be on 10th Mar (US date), the pricelist is suppose to release next week but seems like there are lots of sources by The Register here.

VMware have also release the hardware compatibility list here with more vendors support other than Dell in the public beta only.

This will be very exciting moving forward.

Update 12th Mar 2014

• VSAN What's New Technical White Paper here.
• VSAN Quick Monitoring and Reference Guide here.

Update 13th Mar 2014

• Advanced setting requirement to all hosts for VSAN node exceeding 16.  Refer to KB2073930.  William Lum from VMware has document this why it is needed on his blog.
