SCSI Adapter for HP Ext Dat Tape Drive

By cshanyee ·
I just bought an external HP Surestore DAT 40 tape drive. And I have a Windows 2000 server with 1 Ultra 2 SCSI Adapter. My question is can the tape drive use the same scsi adapter as the hard disk? Do I need to buy a separate scsi adapter for my tape drive?

thanks

SCSI Adapter for HP Ext Dat Tape Drive

Much really depends on the SCSI adapter. Does it include an external interface? Is it a multi-channel or single-channel adapter? What other SCSI devices do you have connected to the adapter?

The SureStore DAT40 uses a Wide Ultra-2 interface. While this will work with a standard Ultr-2 adapter, theoretically, you are losing half the possible transfer speed (Wide Ultra-2 - 80 MBps vs. Ultra-2 - 40 MBps). However, since the DAT 40 only has a max sustained (compressed) transfer rate of 21.6MBps, in reality you aren't losing anything.

Therefore, as long as your SCSI adapter includes an external interface, and you have 6 or fewer other SCSI devices connected (Ultra-2 standard allows a max of 8 SCSI devices (including adapter); Wide Ultra-2 standard allows a max of 16 SCSI devices (including adapter)), you should be able to use your existing adapter.

Thanks. I manage to install HP Surestore DAT 40 tape drive without any problem on existing SCSI adapter. My SCSI adapter does support external interface.

I have been happy with Adaptec U160 & U320 cards.
