Mixing Ultra2 and Ultra3 drives

Compaq DL380

What are the risks, consequences involved in mixing Ultra2 and Ultra3 SCSI drives.

Will the Ultra2 transfer at 80 MB/s and the Ultra3 at 160? Or, will all drives transmit at the fastest common speed, in this case 80 MB/s?

Is there greater risk of hardware failure or data corruption when mixing SCSI standards? Do the drives have to be placed in any particular order with respect to type?

Thanks!

Dan

Re: Mixing Ultra2 and Ultra3 drives

There are no "Problems" with mixing the drives. The SCSI controller will sync the data transfers within RAIDs to the common protocol.
Here is a document that explains most of the compatability and issues:

Enjoy!
