Service manual (http://support.dell.com/support/edocs/systems/pe2650/en/sm/index.htm) says: "Support for up to five 1-inch, internal Ultra3 SCSI hard drives (with hot-plug capacity when using the optional ROMB card)." The 3/Di ROMB was Adaptec, still supported in Linux by the aacraid driver. The 3/SC and 3/DC add-in cards were LSI, still supported by megaraid driver. I run a 3/DC in my venerable Precision 530 home server on Fedora 12. Haven't seen a 2650 with the internal drive backplane connected to a SC or DC add-in, but the drives should also be hot-swappable in such a config. You just can't hot-swap if connected to vanilla SCSI. BTW, Ultra3 is not "required", just the practical speed limit for the PERC 3 generation. You can drop U320s in and they'll just step down to U160 speed. Throw in an Ultra2 and they'll all step down to that speed. _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
