SAS hard drives description acronym question...
sorry, me again!
In the descriptions of some SAS hard drives there is an 'SP' specified, and we can't find out what the meaning of this is ANYWHERE!
for example:
HP 146GB 3G SAS 10K SFF SP HDD
we know what all the rest is (well, except the 3G - but I'm taking that to mean 3Gb/s SAS throughput spec?)
So, what's the "SP" all about?!?
as always, many thanks for the help! :-)

I don't know what it means either, clearly it's not storage processor since that applies to the controller, not the disk. I'd ignore it and just look at the other stats, you'll notice that single track seeks are slower than the other SAS SFF disks so it might be something about the positioning, clearly not slow positioning though. If you're really concerned I can ask HP presales next week. I doubt it's anything to do with the SP state machine that looks after startup and connection speed negotiation - I can't find out what SP means in that either!

After speaking to a couple of very knowledgeable people over the weekend I can see that it probably is Single Ported. Thanks for the assistance everyone! :-)
