It's time to build a new server. My old one (a re-purposed Celeron D 2.9Ghz / 768M FreeBSD box with a a 1.5 TB raid on a Highpoint card) has hit a wall in both performance and capacity. gstat on FreeBSD shows me that the Highpoint raid array is the main bottleneck (partly because it's in a regular PCI slot and partly because it's really software raid with crappy drivers) and CPU is a close second. I'm going to build a new box with SATA disks and a better raid card. So my question: Has anybody does any actual benchmarks on BackupPC servers? Which OS & Filesystem is best? (I'm, leaning toward Ubuntu and RaiserFS) RAID cards that work well? Allow for on the fly expansion? RAID mode ? 5? 6? 10? 500GB drives seem to be the sweet spot in the price curve right now - I'd like to get 1.5TB after RAID so 6 drives in RAID 10. I'm leaning towards a core 2 duo box with 2Gb of ram. Any hardware to avoid? John |
