build your own network attached storage device
Robin Harris over at the Storage Bits blog goes over a new UW-M paper analyzing the fault tolerance claims of ZFS.

Legit Reviews takes a 6Gbps SATA/SAS LSI RAID card for and spin and ends up with a lot of performance graphs.
Today I have LSI’s latest RAID card, the MegaRAID 9260-8i SAS 6Gbps controller. Featuring a compact PowerPC RAID-on-Chip controller, 512mb of DDR2 cache, a PCIe 2.0 x8 slot, and SAS/SATA 6Gbps connectivity, the 9260-8i is one well equipped RAID card. Marketing documentation boasts of maximum 2875MB/s reads and 1850MB/s writes through the 800MHz PowerPC LSISAS2108 ROC, well over three times the throughput limits of the ICH10R controller built into Intel’s desktop platforms.

This post will explain how to set up a NAS server with Debian running essential services such as ssh, samba, nfs, cups, rdiff-backup and rtorrent with a web interface; and using two HDDs in RAID 1 mode with everything encrypted. It took me awhile to research all bits and pieces, hopefully it will save you time if you are going to do a similar set up.
