It's not just U2 that likes to have multiple spindles.
Any disk intensive processing activity will benefit by having the load
split accross multiple disk subsystems.
Agreed .. So why when we bought our new RS6000 about 1 year ago did the IBM
guys try to sell us on a SMALLER number of LARGER
Subject: RE: [U2] many spindles - was Copying data between two UV servers
It's true that it's getting tougher to justify 4 spindles that happen to
be 36gig each for a database that is only 15gig in total size. But the
speed difference that is achieved by splitting the data files between 2 sets
Gotta look at the disk specs. All things may not be so equal. Disks are getting
faster and smarter as they get larger.
Latest disk speeds are 15,000 RPM vs. 8k or 10k. Faster SCSI buses, bigger caches and
smarter access algorithms on both the drives and the controller cards boost I/O
FWIW, our newer disk cabinet with faster SCSI controllers and higher disk
RPM
(but fewer spindles) blows away the older one that has 2-3 times the
spindles. :-)
but 36 GB drives that cost a lot less, and that are a lot faster, and last
a lot longer
It's actually hard to think that a shop
