Currently active:
() Compaq SmartArray 5302 (64 MB) with five Seagate X15's (18 GB first-gen 15K) in RAID5, two 72GB Atlas 10K3's in RAID0, and some 2.1 GB drive (7.2K RPM, going to end up a a shelf ornament Real Soon Now) all in a nice 3U NEC rackmount unit. Looking for a way to fill the remaining 6 spaces without breaking the bank.
() Two 72GB Fujitsu MAT (I think, damn Fujitsu and their naming scheme) 10K drives in a Sun Ultra 2, using the onboard controller whatever that is. Seperate volumes.
() 73GB Seagate 10K.7 on some form of an LSI 1600 (Elite 1600 IIRC).
Inactive:
() IBM ServeRAID 4Lx (have yet to find a motherboard that likes this card, they either seem to freeze during POST or run slower than a floppy drive).
() 4x9.1 GB full-height 7.2K drives. Can't recall who made 'em. Too loud, too hot, too slow, not worth the shipping cost to send them anywhere, probably going to end up as doorstops or something.
() Adaptec 20 MB/sec PCI card, forgotten the name. Same as the 9.1 GB drives, just sitting in a box somewhere and not worth the effort.
Long-term plan:
Eventually, I'm going to consolodate everything into the NEC unit and run everything over iSCSI and NFSv4 backed by raid-z. Additionally, I'll be adding four 320GB 7200.10's (with another 4 drives later once I start running out of space again) as bulk data storage. I've got most of the parts together for the iSCSI stuff (nice Intel gigabit NICs, jumbo-frame supporting gigabit switch) and just need to find a weekend or two where I can buy the drives, back up everything, reformat, and get everything set back up again. This should give me 72 GB of Really Fast space (15K drives, using one as parity), 288 GB of Quite Fast space (10K drives, using one as parity), and 960 GB of Average Speed space (7.2K SATA drives, using one as parity) growing to 1920+ GB when I add the other four drives. All nicely bundled up into 6RU of space and with 4 SCSI and 2 SATA spaces to spare
