I need a SATA RAID PCI card that works well with CentOS and is fully supported. Mandatory features:
- works with the drivers already in the kernel, no additional drivers
- can do RAID 0, 1 and 5
- hotswap
- allows to monitor the status of the array and of each individual
drive via a script (ideally run from cron)
- works with very large SATA drives
Nice to have features but not mandatory:
- small battery to keep the array alive until the write buffers are
flushed after a power loss
Anyone having positive experience with SATA RAID, please comment.
3ware. Period. 9550/9590 will do everything you want. 9650 gets you RAID6, but I'm not sure the distro provided drivers have caught up yet.
9500 is the PCI card 9550/9590 is PCI-x. 9500 works out of the box in CentOS 4 as I have used it there. For hotswap, you need a drivecage that also supports hotswap. The 3ware cage does, and comes with all cabling to get drive lights working. They hold 4 drives in 3 drives/half height 5 1/4 space.
