I want to buy SAS (both host and disk interface) disk array with 4 SAS wide host ports. I'd like to connect to the array 1 server (preferably using 2 ports, separate HBAs and multipathing), but additionally also 4-5 rack workstations. Is it possible to connect more machines than the number of SAS ports? If so - how? What other hardware is needed?

SAS Switches do exist. HP has one for the BladeSystem, and I found mention of one from Rancho.

Didn't know that, thanks for the tip. – Massimo Aug 31 '09 at 21:27
Yeah, we're looking into HP MSA2000sa G2 so I had seen info on the switches. – AJ. Aug 31 '09 at 21:51
