I've finally started to test the newer versions of RedHat 6.x and Scientific Linux on HP ProLiant hardware. My previous installs were in virtual hardware, so I didn't notice the raid controller driver change. The first thing I realized on a physical installation was that the drive array devices are now SCSI
/dev/sdX names versus the longtime
/dev/cciss/cXdX block devices.
Apparently, this is due to a new device driver,
hpsa instead of
cciss. Can anyone shed some light on the differences between the drivers?
What's gained? What's lost?
Is there any performance impact?
Is there any overlap in terms of the card supported?
Has there been a similar change on the Windows side?
