I’ve long been a fan of of the discontinued APC AP9211 distribution unit. To wit:
- It’s an efficient 1U, taking up just enough space for the 8 outlets.
- It is gloriously devoid of any moving parts, including noisy fans.
- powerman comes with scripts to manage its outlets from the command line over ethernet. Once you get used to the convenience of “powerman -c $host” you never go back.
- It’s common enough to easily be found on ebay.
That last point brings us to this post. Mark got a pair for his machines after I showed him the light. He got them from an auction that has 3 days left and, at the time of this writing, 19 units left. Each has a pretty reasonable price for immediate purchase with shipping.

It’s a chance for poor kernel developers out there to stop being frustrated by having to lose time rebooting boxes in person.

I’m very excited. In a small number of hours someone from the PostgreSQL project will be coming by to take away my old fiibre channel storage setup. I had used it for OCFS2 development, mostly, but haven’t touched it in ages. I do hope it works out well for them. It consists of the following:
- 8 incredibly long copper cables
- about a million (ok, 11) copper GBICs
- 8 qla2100 PCI cards (these are not excellent)
- A tray of 10k rpm Cheetahs, complete with funky NetApp firmware, which could kill a man who attempted to lift them unaided
- a fibre channel switch whose fans could then wake said dead man
Did I mention the excitement? This crap — er, fantastic storage infrastructure — will no longer take up space in the basement.
These days I do my storage work on an HP DS2405 which is directly connected to an Emulex LPe11002, both donated by said companies. The old setup could hit 100MB/s on a good day. The current kit hits 450MB/s without trying very hard. If you have the means, I highly recommend picking one up.
