Understand. And you have to switch your root in that case as well, but you can do that in the entry too. You also have to train staff and/or write scripts for kernel updates. But it's still often not automated, and requires manual intervention. Hardware RAID is, even if just for the "system disk." > No need for dmraid or fakeraid for peace of mind on a home system.

And all 10-15Krpm drives are always fabricated at 2.5" platters**, if performance is a consideration. -- Bryan **NOTE: Some vendors package 10-15Krpm 2.5" platter drives in 3.5"x1" to 3.5"xHH form-factors, to fit in more platters (and additional, thermal contact on the sides), than they can in a 2.5"x9.5mm, 2.5"x12mm or 2.5"x14mm. -- Bryan J Smith Senior Consultant Red Hat, Inc Professional Consulting http://www.redhat.com/consulting mailto:[email protected] +1 (407) 489-7013 (Mobile) mailto:[email protected] (Blackberry/Red Hat-External) -------------------------------------------------------- You already know Red Hat as the entity dedicated to 100% no-IP-strings-attached, community software development.
