Hi all
I am fairly new to prox, but I am an old hand at linux so I learn fast, and I wont waste your time. I have done some research on HA and DRBD and want to try it.
I have 4x dell R720 with 2x600GBsas (raid1) + 4x600GBsas (raid 10) - so 2 hds per server effectively. I want to use the first hd for the OS/prox and the second hd for the DRBD/HA/CTs.
Specs:
prox 3.4 latest
dells with 6x600Gb SAS 15 rpm in 2 raid sets as per above.
Here are my questions:
How to do a 4 way DRBD setup. I know I will lose much hd space, but can it be done without stacking etc?
Or do you rather suggest I go for sets of 2 ie 2x2? If this is recommended can I still have my 4 dells in one cluster? I assume you can but then HA will work in pairs eg dell 1&2 and dell 3&4?
Here are my goals.
HA failover to at least 1 server (sets of 2), but I prefer failover to all (4 servers)
A single frontend on say dell 1 where I control all the other dells ie just like a normal non-HA cluster.
Then lastly if I do 2 pairs of 2 servers, would i be able to login to the frontend of any of the 4 servers and migrate a CT from pair 1 to pair 2 (keep in mind their DRBDs are separate)
I just want simplicity and HA at the end. Simple answers to my questions are ok, I can research the rest, I just need some guidance. Thanks all.
Admin can you send me some information on the costing on commercial support? Thanks.
