Well, the servers we bought (Dell R200) were in fact very
cheap. We were using 2 of them and they could not stack up
to 4-5 year old servers (Dell 1750 and 1850) which have SCSI hard
disks.
I added a 4 year old Dell 1850 with SCSI disks next to the 2
R200's which were all connected to a separate server running
pound load
balancer. The total number of maximum concurrent connections
tripled. The Dell R200's cannot actually take SCSI/SAS
drives (unless you go buy a proper controller). By default, they
can only take Nearline-SAS which I heard is not something you
would want for a web server.
I would have to say that I am putting the blame on the SATA
drives. I would have thought that by now, SATA drives would be as
fast as old SCSI drives, but I guess not.Apart from that, I am
still surprised that the new R200's with EIGHT Gbs of ram could
not keep up (not even close) …
