Hello, I'm looking to build a CentOS server (or servers) with a SAN to support a large user base.
The storage solution will depend heavily on the topology.
All servers in same closet (same 25'): Serial Attached SCSI (SAS)
All servers within the same building: Storage over TCP/IP (iSCSI) or Fibre-Channel Arbitrated-Loop (FC-AL)
Furthermore, I need to know ...
- Your apps
- Your clients
- Other uses of the storage you can think of
Mail (POP/IMAP/Webmail), that's it. 50K to 100K users. Client is not happy with his current vendor. All the servers would be in the same building, likely in the same cabinet or adjacent cabinets.
Question: if you had a budget of $25K (or more if necessary), what you build?
I apologize for this, but I'd feel I'd be professionally negligent if I didn't at least point it out. If you have $25K to spend, and can afford recurring costs of $1-2K/year, then I'd highly recommend RHEL AS for the support aspects.
I'll ask the client to consider that.
Thanks.
