Caution!1.6"
The use of part numbers for Power Systems configuration is not a great
idea.
IBM Uses feature codes because the underlying part number can AND DOES
change. This may include sourcing parts from multiple suppliers (they
ALWAYS do this) as well as changes in the part over time. That said
even the feature code can appear to change for the same drive or I/O
adapter but in those cases the change typically indicates a different
mounting configuration. (e.g. Sff-1 Sff-2 or Sff-3 for disk units.)
While it's probable that a part number search will yield results it's
also very probable that it will miss valid results.
A classic was the old 4GB SCSI disk unit. Those things came in more
part numbers than you could shake a stick at. They physically changed from
to 1" drives, changed the style of the case completely, embodied maybe--
a dozen manufacturers and yet if you had a 6607 it worked! This was
also a good example of finding the same disk unit with different
mounting. These things went into model 400s with NO mounting into 170s
and 620s and 720s with a blue handled sled and into older 3xx and 5xx
models inside a complete enclosure that even had another board in it!

Thanks Larry, Rob, Diego, Jim, EdThis is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing
Point taken, I'll ask the BPs.
(this is 11 such disks in a Raid5 configuration, perhaps not that
bad?)
Googling this drives I only found them (Part No. 00E9953 )
configurable for a P8 machines.

Do you have the part no. for a Power 9 machine?

They are in the list but don't buy 'em! Even for test and dev those
things are slow. At least get the 15K Drives and a few more of them.
For test and dev you may find that the read intensive SSDs will work
for you also yilding vast leaps in performance at reasonable cost.

Hi Techies.machines.
Looking at (competing) quotes for a new S914 (P9) dev. machine:
one BP configures 1.1TB 10K RPM SAS SSF-3 disks the other BP says
these disks are not configurable for S914 IBM i
Who is correct?
TIA
