Hi Guys,
We're looking into setting up a new infrastructure using vSAN to possibly save on hardware costs. I'm like to know 2 things...
Any info will be greatly appreciated.
Thanks.
Nick.
When you choose a box make sure the Raid controller card is JBOD (Pass through)...which allows VSAN to manage your disks to create disk groups. The alternative is that you have to set up each disk as its own a RAID 0 for VSAN to see the disk. Then you will have to go to the Esxcli console and mark which ones are SSD by command line. Could be a pain on lots of hosts and lots of SSD's. I had to do this with a PERC H710.
So far I am impressed with VSAN. I had a host failure (RAID controller card) a few months after...other than a few hiccups..everyone has been working as normal on the remaining two hosts with the cluster basically broken.
I tested lots failure scenarios before this...Yanking power on a host to see what happens while test users were working on VM's on that box...and everything so far was impressive. Users lost connections and in two minutes were able to log in. Their VM's were on another host..with NO physical connection between the offline host. Really amazing stuff so far..
Nick,
A couple things:
Lots of great resources around to assist.
