Guys, I'm in the process of ordering a new server for my work and I want to get one which can handle 16 to 24 drives. But with so much disk capacity I was wondering what people to do make the file systems secure. In the past I've used either raid 5 or raid 6 arrays. The idea being that if 1 (raid 5) or 2 (raid 6) drives died, you were OK, all you had to do was replace the drives and the rebuild would occur and you were fine. But then one day I had 4 drives fail at once. It wasn't the drives that failed, but the disk controller. I had added a 4 port SATA card to my server so that I could add for more drives to my server. So now with getting a server with such large drive capacity, I'm wondering of all this raid stuff just gives on the warm fuzzies, but in fact you are just as vulnerable since you controllers can go and knock out half your drives (or whatever). Any comments on how to deal with say a 16 disks and what's the current lore on making large redundant disk arrays? Thanks in advance! Cheers. Steve.
