I have a Dell SC1425 which will be running CentOS x64 and which has an
on-board Adaptec CERC RAID controller. I also have a cheap Syba
SD-PCXSA2-2E2R SATA II RAID controller
My question is, are both of these cards/controllers simply BIOS
controlled SOFTWARE RAID controllers? The reason I asked is that on my
first test, I simply pulled the SATA cable off the first drive after
building a RAID-1 array and installing CentOS. The system just hung
until I rebooted, but it did boot with degraded array. After shutting
down again and plugging in the first drive, it did not "appear" to
rebuild the array automatically, but I am not sure.
I have been using 3ware controllers for years with no problems and am
trying to save a few bucks by using the on-board, or Syba controller,
but if they are both software RAID, then I guess they wont support
hot-swap and so thats why the test of pulling the drive while running
hung the system? With the 3ware controllers I can get alerts when the
array is down, or rebuilding and can access the controller through the
3Dm interface.
Basically I would like the ability to have the system remain up when a
drive dies, and of course to automatically begin rebuilding the array
after replacing a dead drive. I suppose I might hear what I suspect all
along, go with the 3ware hardware solution.
Thoughts, suggestions?
