I am currently trying to spec out a new mail server for running Postfix/Cyrus-imapd for more than 10,000 e-mail accounts. I think I'm going to want to go RAID 5 for the capacity. I would like to have a management interface to the array that permits a high confidence that a junior admin won't accidentally rebuild the array from the new drives rather than the existing, remaining members of the array if I'm out of town when a drive goes out. I've had that happen at past employers. I don't want any dependence on X for the management utilities. I want to be able to add drives and build an array without going to the BIOS if I need more disk space in the future. I have an Intel SE7520JR2 motherboard to build the server around. Are the Intel RAID controllers all re-branded LSI boards? From some of the mailing list posts, I get the impression that at least the SRCU42X is an LSI chipset. -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
