I have so far not experienced any problems with ciss-controllers on
Proliant G2, G3, G4, especially not with DL360 and DL360 (or MPxxx either)
ciss0: <Compaq Smart Array 5i> port 0x2800-0x28ff mem 0xf5df0000-0xf5df3fff,0xf5f80000-0xf5fbffff irq 31 at device 4.0 on pci0
ciss0: [GIANT-LOCKED]
ciss0@pci0:4:0: class=0x010400 card=0x40800e11 chip=0xb1780e11 rev=0x01 hdr=0x00
vendor = 'Compaq Computer Corp (Now owned by Hewlett-Packard)'
device = 'CISSB SMART2 Array Controller'
class = mass storage
subclass = RAID

ciss0: <HP Smart Array 641> port 0x3000-0x30ff mem 0xf7f80000-0xf7fbffff,0xf7ff0000-0xf7ff1fff irq 24 at device 2.0 on pci2
ciss0: [GIANT-LOCKED]
ciss0@pci2:2:0: class=0x010400 card=0x409a0e11 chip=0x00460e11 rev=0x01 hdr=0x00
vendor = 'Compaq Computer Corp (Now owned by Hewlett-Packard)'
device = 'Smart Array 64xx Controller'
class = mass storage
subclass = RAID
I especially like that rebuilding of raid 1 and 5 is done automatically.
You'll get entries via syslog about failing drives, and just removing
that drive, inserting a spare one, will start rebuilding which is also
syslogged. Very nice. No Problems so far, and no system failure. Regular
backkups still recommended, though ;-)
