Depends, are those 10,000 messages local deliveries? just queued mail
going out? I am using IDE drives for the qmail queue and NFS for
the maildir spool space. (On 3 PII/266-350's) and we deliver apx 140,000
messages a day. (Thats remote and local) ... most of those are incomming
local messages that go though the qmail queue and deliver onto the NFS
spool. Most of that is done on only one machine. The people reading all
share the same 3 machines, we have one other machine that is doing
listserv deliveries that I am not counting in my 140,000.
If I was delivering locally to local drives, I would use RAID to hold the
spool space, but probably still use ide to hold the queueing space,
nothing like hot swaping a drive and not losing any data or even having to
bring the spool space down. For the load I'm seeing on the IDE disks
currently doing queueing, I don't see any reason to move to SCSI.
If I was trying to deliver outbound millions of messages a day then I
would probably talk about moving to SCSI drives or maybe something faster
than that... but for general use why bother...
On the other hand speaking of delivering these huge mailing lists..
wouldn't it be more cost effective to purchas a second PC load linux and
use them both to split the queue load. :) When you can get an entire PC
for $500 and a SCSI card costs $120+SCSI disk... why not just purchase
another PC to split the load. That gains you 2 Ethernet channels/2 Memory
channels/2 xxx/redundance/failover and a boatload of other benifits...
Just my thoughts.
