Hi All,
The current system is a PE2550 with 4 x 36GB U160, 10000rpm in a RAID5 array
via Perc3Di.
The array is RAID5. Dual PII 1.3ghz 2GB of ram and the standard dell onboard
equipment. Gigabit etc...
I think that except the storage part it would be able to cope with the load
just fine if you get rid of the Perc3/Di and us a /DC or /QC instead.
Dual Xeon 2.4GHZ, 3GB of DDR RAM. A single 18GB mirror for the OS and
internal files (logs and db apps etc..) and then a PowerVault for the
external spool.
Mirror the OS as well, it's stupid to not mirror the OS drive, if you have
to wait 4 hours for the techs to arrive that means 4 hours no server plus
the time it takes to install an reconfigure the server.
The PowerVault would need to do RAID5 for disk spool of say 250GB. The
PowerVault would need to be connected via the external SCSI port on the new
server.
Don't use raid 5 for the mail spool, I suggest using raid 10 instead.
Mailservers behave much like database servers and raid 5 is very bad for
the performance for either application.
You could use a 6x73 or 6x143 raid 10 which equals 210GB or 420GB.
And I suggest using the Perc3/QC in this combination which works reasonably
well.
Cheers

It might just be your lucky day, if you only knew.
