Re: model 270

running mission critical operations on any server with less than
premium drives (or any other parts) is bad for the business (and if
management doesn't support the idea and cost of quality servers then
thats just bad management...) Very, very few  companies can
operate well without a mission critical server.
Which brings me back to the original post - why would you

in a mission critical position in your network?

The technicians here say they average replacing about 20 hard drives a
year in various PC's.  WAG is ~300 pc's and ~15 servers.

I've replaced several drives in my various flavors of AS/400's and
iSeries.  Currently we have 119 total drives in all four boxes.  Don't
know how many per year.  But it's safe to say it's definitely less than
the seven or eight represented by the ratio of
119 * (20 / 315)
which may be flawed because I am sure that a couple of those servers have
multiple drives.  But that's probably more than offset by the number of
servers that are IXS cards.  (and all the WAG involved)

OK, not fair.  How about a similarly sized Maxtor 18GB Ultra-320 SCSI 15K
for $75, or $4.16/GB.  New.

Unfortunately your comparison is apple/oranges.  If you compare drives
from those same manufacturers that are rated for the same MTBF and service

type, you may have an argument, however the drives you site are not
manufactured  with the same tolerances.  We have had this discussion
before. The drives you site in the comparisons are not equivalent drives
from those manufacturers to the ones IBM uses in its enterprise class
servers (z, p, & i) .  Even Hitachi who manufactures a very high
percentage of the drives for IBM has two models in the 17 gig variety. One

for real server usage (i, p, & z) , and the other for the consumer market
and folks that do the very comparison that you just did.

Sorry if I just won't bite on that argument.
