Specs: server 2003, 4gb
On a IBM X Series 235 server, I am wanting to add more storage. I have 4 - 36gb drives and want to add 2 - 73gb in the other slots. Is this possible and ok?????

Presumably you have the 4 disks in a RAID array? (RAID 5 I'd guess.) There's no problem with using different sized drives in the other two slots, but you won't be able to add them to the array (well, you can but you'll only be able to use 36GB on each disk). But you can pair them in a separate RAID 0 or RAID 1 array or use them as individual drives.

I have actually upgraded the disks on a X Series with a RAID 5 array by replacing a 36GB one with a 72GB one, letting the array rebuild and then repeating the process until all were replaced. It takes a while, but it works.

You have ultra 320's scsi I assume.

You bet you can add more space. Never has scsi drives been so cheap. I have seen a 146G ultra320 for $30. They used to cost more than ten times that only a few years ago.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
