( the R220's had awful ACPI problems which muck up serial access) A lot of these are single SSD systems with a few mirrored sata + L2 SSD's for caching I've read that ZFS prefers direct access to the disks, does anyone have info/insight as to running zfs via these percs? thanks Paul. -- ------------------------- Paul Macdonald IFDNRG Ltd Web and video hosting ------------------------- t: 0131 5548070 m: 07970339546 e: paul@ifdnrg.com w: http://www.ifdnrg.com ------------------------- IFDNRG 40 Maritime Street Edinburgh EH6 6SA ---------------------------------------------------- Virtual Servers from £50.00pm High specification Dedicated Servers from £150.00pm ----------------------------------------------------
