It looks like you are using the 3Ware Escalade card as "just a bunch of disks" (JBOD) and not using hardware RAID-5. Is there any reason you're doing this? Kinda seems to defeat the purpose of the card? Also be sure to always update the firmware of the card to the latest, and match it with the latest driver. Running an older firmware with a newer driver is never ideal. -- Bryan P.S. I agree with your design of a RAID-1 (or RAID-10) "system" and RAID-5 "data." I use 3Ware Escalade 8 and 12 channel cards all-the-time in this exact configuration: 2+6 and 4+8 for RAID-1/10 and RAID-5 on 8506-8 and 8506-12 cards, all respectively. -- Bryan J.

Any tax rate that penalizes them will also penalize you similarly (to those below you, and then below them). Linear algebra, let alone differential calculus or even ele- mentary concepts of limits, is mutually exclusive with US journalism. So forget even attempting to explain how tax cuts work. ;->
