Then DROP the idea of hw-raid. Get a damn good SATA/SCSI/SAS HBA, and use software raid. BTW, damn good means no VIA, SiS, nVidia, or other el-cheap-o half-broken SATA
Can you give some examples for a good SATA HBA?While I’m quite convinced that software raid is more flexible than hardware raid (at least for RAID 1), I know that I can do hotplug stuff with my 3ware (or the PERC 5/i in our Dell servers). And the last time I checked with the kernel SATA support, hotplugging disks was not very well supported.
With my 3ware controller I can use tw_cli or the GUI to rescan for a new disk or to remove it and I use this feature for backup. How would I do this with a „normal” SATA controller?
Shade and sweet water!
