[PVE-User] PVE HBA best practice

[Stefan Sänger]

Hi Gilberto,

the Powevault MD1xxx series are only shelved with SAS support, but 
without the actual controller. They are intended as expansion units - 
either to a single server (which is basically like making the case 
bigger and adding more disks) or to extend an actual storage.

If you go for a MD3xxx device you actually get what you want - available 
with SAS, FC or iSCSI.

Whila a storage switch for this is recommended, with only 2 attached 
servers it is not necessarily requried.

HA solution then leans towards LVM storage.

We actually have a HA solution including SAS switches and 10 servers 
(mixed, 4 rack servers and 6 blades in a small bladecenter) running for 
a couple of years now.

I would always recommend using Switches and setting up multipath here...


best regards,

Stefan
