Your server came with a Wide-Ultra SCSI-3 Drive Cage so you would have to purchase the optional ultra2/3 drive cage. Note that if you change the drive cage to the Ultra2/3 your original hard drives will not fit. Feel free to call 1-800-ok-compaq if you have any further uestions.

Will a 15k drive work in the drive cage ? <BR />If one on my 18.2 gig breaks down can I replace with a 18.2 10k drive. <BR /> <BR />thanks Mon, 14 Jan 2002 00:00:00 GMT https://community.hpe.com/t5/disk/adding-new-drive/m-p/2643894#M2083 Ayman Altounji 2002-01-14T00:00:00Z https://community.hpe.com/t5/disk/adding-new-drive/m-p/2643895#M2084 If you are referring to an Ultra3 15k drive, it will not fit.
