Let's start with the auction title:
Sun Storage A5100 Array With Drives Nasa Computer NiceWithout going any further than that, it sounds like a disk array for Sun computers that had been owned by NASA.
From Sun's web site, it came in two configurations, 18gig and 32gig. It may be heaper just to go to your local PC superstore and buy a terabyte drive and PCI SATA card.
At
http://www.sun.com/software/solaris/cluster/specs.xml it's listed as a fiberchannel unit. You might look into some similar SCSI units on this page, but it's probably still cheaper just to buy a huge hard drive and PCI card today.
Are there drivers for OS3.x with a PCI bridge for SATA?
