Ideas regarding creating a "Hot Spare Server"
Posted on 2007-10-07
Well, to be frank, even a warm or cold spare server would probably do the job, but still...
A client of mine has a Win2K3 SBS server that does so much for them. Domain, Email, File Storage, Print Server... currently, we perform tape backup using Veritas with Exchange agent, we have a second domain controller (a Win2K Server box), and I do occasional VMWare converter clones of both servers (although I have never tried to boot them up). Regardless, I bet that we are looking at some serious downtime if the main server has a catastrophic failure of some sort.
I think my dream solution would be a hot spare server, running identical (or close enough) hardware, that just sits there, mirroring every change on the original server and can step in when needed. the switch over need not be automatic, mind you...
I am envisioning it as a RAID 1, but of servers, not drives.
Cost is definitely a factor (as always). But I can make a pretty compelling case to spend a few grand.
Let me know if I can provide more details. I encourage any and all theoretical posts. 3rd party product suggestions are welcome.
Thanks and I look forward to your thoughts.
