i just installed a shiny new Xserve G5 with two Xserve RAID Units. Each Xserve RAID unit has only 7 drives. Each of the Xserve RAID units is connected to the single Xserve G5, off the single Fibre Channel card.
Each of the Xserve RAIDS has all of its 7 drives set up as a RAID 5.
On top of this, I mirroed each of the RAIDS via Disk Utility. Effectively this gives me a RAID 51.
Within a day or two the mirror had degraded. I’m in the process of doing a backup now.
Has anyone else tried mirroring two Xserve RAIDs together?
Is it a better idea to put all 14 drives in a single Xserve RAID chassis?
When I rebuild the mirror, can the server still be utilized during the rebuild?
Thanks,
All information, insight and knowledge is greatly appreciated.
