Yes, you heard it correct. VMware Virtual SAN (VSAN) is now GA as of 03/11/2014. VMware released VMware ESXi 5.5 U1 and vCenter Server 5.5 U1 which includes the VSAN GA bits. VSAN resides in the native ESXi 5.5 kernel so no requirement of deploying any virtual appliances or anything like that. All you need to do is acquire your license key(s), enable VSAN and off you go. So check out the links below for more information.
VMware’s VSAN product page.
Chris Wahl has published a great post to get you started on the right path to using VSAN. I highly recommend checking it out.
Duncan Epping has some great posts around VSAN. (Shocking right? :) )
Rawlinson Rivera (Captain vSAN? :) ) has many great articles over at his site as well.
For a look at VSAN pricing head over here.
I can tell you from my early beta testing that this is a very compelling solution and highly robust. If you are interested in setting up a VSAN ready nested ESXi lab you can get started with a powercli script that I created a while back.
