compatibility Ultra3 SCSI Module and Ultra320 Hard disk

[Socoboy]

Good morning all,

Can you confirm me that a hard disk Ultra 320 is compatible (it works , but after 10day, it's crashed) with an Ultra3 SCSI Module (older)?

thanks,

[tripper91]

cannot say for certain that is is capatible or not but i have an ml370 g2 with U3's and U320's. What model is your server?

Hello SocoBoy,
Ultra3 SCSI works at 160 MegaBytes/Second.

Then came Ultra320, works at 320 MegaBytes/second.

SCSI devices are always backward compatible. When newer SCSI devices are attached to a system with devices from a previous generation, the newer devices will back down to the maximum operating speed of the older generation when they are talking. When not talking to older devices, the newer devices operate at their normal speeds.

Hence, yes they are Compatible, but at a Price of LOWER SPEED.

Regards,
James.
