I'm building several servers to become Groupwise Post Offices(7.02HP1a). We are having speed problems with our current single PO. I built a second and moved some people and they are now happy. I have been using some extra severs we bought but never configured last year. They will be running NW 6.5 sp6 w/ patches. They are quad core, 4Gig RAM with RAID Card. I built the first with RAID5 + hot spare. After thinking about it I wonder if NW/GW would benefit from RAID10+ hot Spare. I can do the other two either way since there is a pile of Hard Drives. Any Thoughts? Thanks!
