HP Hot plug Ultra320 replacement

Has anyone ever tried to use a different brand of hard disk in an HP Ultra320 hot plug cradle? The only sizes available from HP are either 146 or 300... nothing higher. I tried putting in my own SCSI drives in the first generation of HP hot pluggable hard drive cradles and it kept on failing. I think they have special firmware to work with their RAID controllers in their hard disks. Does anyone have anyone experience doing this? Any shared knowledge will be greatly appreciated.

The hot plug cradle of HP is proprietary to HP, i.e. not an industry standard, so having alternatives from other vendors or manufacturers that might really work with it, is not nearly possible.

This applies to other manufacturers as IBM, Dell, ... etc.

I think you art stuck with HP, unless you choose to use an external scsi storage solution, or got some SAN/NAS solution.

I am using HP's cradle but changing the drive. Has anyone tried this before?

There is nothing in the firmware that looks for certain make/model of disk drive. (This assumes you are using a SMART Array controller) under Windows or LINUX.

Just be aware that if you just slap in any disk drive that the mode page settings may not be appropriate, so configurable parameters that control retry algorithms, write cache, and S.M.A.R.T. settings won't necessarily be optimal.

DLETHE,

Have you tried such a setup and if so, did it perform well for you? Know of anyway the parameters can be copied?

Thanks

Thanks for the wealth of information regarding this matter... for the small amount of disks that we need, I think we have to keep relying on HP until we upgrade to new servers with 2.5" disks. I wanted to use larger off the shelf disks for green reasons rather than to save money on the hard drives.

Thanks again...
