Hi Managers,
I have been looking at the Veritas site trying to figure out how all the
Vx* stuff works together.
Basically I need to put together 2 Sun boxes + shared storage in an
active/passive setup for HA. Services to HA-ize are mail (Sendmail, imapd)
and apache, the storage will hold user mailboxes.
So far I've figured that I need Veritas Cluster Server, but from there
it's all question marks:
1. Do I require VxVM? It seems that VCS needs to "import" disk
resources during the failover process, must the disk resources be managed
with VxVM?
2. Do I require VxFS? I don't forsee much allocation/reallocation of
disk space, nor dynamic growing or shrinking of filesystems
3. Is the Veritas Foundation Suite/HA the product I should get? I
assume it's comprised of VxVM, VxFS and VCS
4. I've read mention of Veritas SANPoint, assuming I'm running an
active/passive cluster, ie. only one node writes to disk at any time; is
this still required?
The hardware I've identified so far is the V480; does anyone have
experiences on what storage to use? My current requirement is for not much
storage (50GB up to 500GB), but I would like this storage to be
"pluggable" into a SAN infrastructure later; will the T3 be a good
candidate for this?
Would be most grateful for any advise and answers, I will summarise.
Regards
Jeffrey
