Does your university have a backup solution you can make use of? The one I work at lets researchers onto their Tivoli system for the cost of the tapes. I think I've got somewhere in the neighborhood of 100TB on the system and ended up being the driving force behind a migration from LTO-2 to LTO-4 this summer. If you are going to go and role your own and use disks, I'd recommend something with ZFS - you can make a snapshot after every backup so you can do point in time restores.

Also, I'd recommend more capacity on backup than you have now to allow versioning. I was the admin for a university film production recently (currently off at I believe Technicolor being put to IMAX) and I've lost track of the number of times I had to dig yesterday's or last week's version off of tape because someone made a mistake that was uncorrectable.

As of Friday, your only options for ZFS support will be (Open) Solaris and FreeBSD. Apple decided ZFS wasn't compatible/ready/something and removed it.

I have data sets spanning multiple terabytes. One recent PhD graduate in the lab I support accumulated 20 TB of results during his time here. Even if I had highly reliable SSDs that never failed, I'd still toss the SSDs together in a zpool to get the capacities I need to accommodate a single data set. RAID is not just about redundancy. With SSDs, I'd probably use RAID5 instead of RAID6 just in case I had a freak bad drive, but RAID in some form is here to stay.

Which story? Quake, Doom, or Half-life (not iD, but originally an iD engine)

I belive Unix was first developed on a PDP-7 as PDP-11s did not yet exist in 1969.

See also Open Firmware on Power/PPC and I believe the firmware interpreter on SGI MIPS systems was also Forth based.

It got MIPS too. At least in the high end server/workstation market. Though I don't miss IRIX.

Last time I looked at LED stagelights about a year ago, the LED PAR64 can seemed to be a drop in replacement for 300W PAR56 lamps. Unfortunately, until intensity catches up to their higher wattage cousins, most of the stages I've worked on are going to keep dropping in 750W HPL, 1KW BVT, and 1K PAR64 lamps. The biggest advantage is its easier to get a blue of out an LED than a halogen, for obvious reasons, but losing the light among the other fixtures isn't really desired all the time.

Some of that is the custom gear that goes into making those beasts. Yes, it might eliminate the hardware raid card, but in the case of the 7210, the hardware to drive 48 SATA drives and not saturate the bus still isn't cheap. Plus hotswap everything, and the price quickly rises to something close to what Sun is charging. I use 4 x4500s at work for a single cluster, and they are a hell of a lot cheaper for that capacity than the traditional rack of fiber arrays/raid controllers/etc. The 4 of them cost me what another vendor wanted for half the raw storage (and far less usable storage).
