Let me explain a little more. We are planning in the next month on buying an
Alteon switch
for layer 4 load balancing and a Netapp filer for maildir storage. My plan is for
3 dell 2300 servers used as front-end machines
running both pop/smtp. They will all NFS to the NetApp for the common maildir
storage.
We will keep a queue on each front-end machine, but in the meantime I have to roll
some mailboxes
to one mail server and that was my orginal question. We are planning on buying one
2300 right now
and rolling all our mail up to it and then breaking it out into the
Aleon/NetApp/FEP's solution when we
get the rest of the hardware.
So, when I order these machines my question remains the same. Do we run the queue
on one fast 10,000 RPM
SCSI drive or do we go with mulitple heads by using a raid controller card running
3 disks on Raid 0? Does it
matter? I figure with the alteon we will easily be able to handle the load by just
adding a front-end machine if
needed.
Thanks.
