Hello, I'm curiuos if anyone knows if it's possible to set up a Dell R515 (which has PERC H700) to be JBOD. It seems the only options are RAID0 or RAID1. I read posts, where people say it can by done by making each disk its own RAID0. This works, but it wigs out when that disk is removed, and forgets a disk was ever there (unless I go back in the PERC and fix it). My plan is to have a system where I can remove and replace the drives regularly, while the system is on/running. I do this on a SuperMicro, but wanted to migrate this server to a Dell.
I tried disabling the RAID in the BIOS, but then the installer never sees the disks.
Any ideas would be great.
Thanks!
Regards, Joseph Spenner

Unfortunately, I don't know any other way, with the PERC in it.

No, that wouldn't work - the PERC mediates between the drives and the BIOS. Until they're set up in the PERC firmware, the BIOS can't find the drives.
One more question: why do you want to regularly replace the drives? I mean, are you including /?

I'm running a backup server (bacula), and the media I use are 7 SATA disks. Every week, I remove 7 disks and replace with 7 new disks. I have a 3 week rotation. Works great. But I wanted to migrate to a new Dell system.
Thanks for the reply!
