What drives does Apple support with the Mac Pro RAID Card and the Xserve RAID Card?
Only Apple drives are supported with the Mac Pro RAID Card and the Xserve RAID Card. Drives can be either all Serial ATA (SATA) or all Serial Attached SCSI (SAS) drives. Question: Why am I presented with the following warning in RAID Utility that the write cache is disabled due to the backup battery lacking a 72-hour charge? Controller reports RAID system 72-hour battery reserve unavailable – System is configured to run without battery Answer: The write cache is disabled automatically to protect data being written to RAID volumes when the battery charge is not sufficient to back up cached data for 72 hours. This message is normally encountered when a RAID Card is used for the first time, when the battery enters a conditioning cycle once every three months, or when a computer with a RAID Card installed is shut down for any length of time. Once the battery has been recharged, the warning messages may continue to appear.
Only Apple drives are supported with the Mac Pro RAID Card and the Xserve RAID Card. My understanding that 3rd party retail drives such as WD RE2 750GB, Seagate, Hitachi were supported as well since the article was written – and I can’t find where I read that, but sure that I did, as this was discussed in the past. I’d like to find an official article.
