Re: Of SANS and IOS

Normally when you buy expensive hardware the saleman should come to you. :-)

Had a quick look in google for IOs and it seems that it is also refered to as IOPs Input Output Per second... And seems to refer to the controller, and not the disks.

And after my quick look, the where talking about cached 20,000 - 150,000 per second.
(Very Very small emc from dell)...

Anyone knows What The FARKS is that IOs unit the HP SAN folk keep

How many bytes is an IOs supposed to be? An IO==Device blocksize or WTF?
When buying serious hardware the vendor is usually happy to allow you to test
it out before you buy.  They should have some sort of demo-room in the
nearest major city where you can plug in your own server and test it out.
