Ok, I’ll chime in too, things to
look for when purchasing a server drive.
Drive: Performance
Mean Seek Time, RPM Speed, Cache, Burst Transfer Rate, Sustained Transfer Rate,
Mean Failure Time
Control
Function
SCSI, IDE, Serial ATA
SCSI
– I can name six incompatible flavors f internal SCSI drives
IDE
– All are backwards / forwards compatible to some extent
SATA
– Two forms, but the first was never in popular use and I believe newer
drives do work on older controllers.
Interface/Physical
connection
What kind of connector do you have? Do you use a standard cable connection?
Or do you have a high-speed back plane?
Hot
Swap
Are your dives/backplane hot swappable?
RAID
What kind of RAID are you using? How will this disk fit in your
configuration? If you using something like RAID 5 and you plane to make
this drive a volume member then you should get the exact model number of the
drive.
Purchasing from some one other then the manufacturer.
I use SCSI-3 UWLVDSCA-2 drives in my
servers, but I never purchase the drives rite from Dell, but since I do put
them as member drives in my RAID I typically purchase the exact same model of drive
each time. I personally like Seagate Barracudas

I can't answer this
question specifically, I can say that in my past experience the only thing
different on the server drives has been the carriers to insert them into the
chassis.
Yes, there are the different spindle speeds and life expectancies, but as long
as you stick with a brands like Seagate or IBM, you should have no problems
with the drives for some time.

Quick question for the group.
I have a friend that is trying to set up an IBM blade server and is looking
for SAS drives.
The IBM drives are around $600-ish and HP drives are $3-400. So he is
wondering if the bladecenter drives are standardized or proprietary.
He's also wondering where in the valley he would find them at a reasonable
price.
He said that the SCSI expansion module in his bladecenter is model #26k4851.
Thanks
