Re: Which External SDLT 320 to buy
look at the bottom of these pages:
http://www.pcguide.com/ref/hdd/if/scsi/protDiff-c.html
http://www.pcguide.com/ref/hdd/if/scsi/protLVD-c.html
And then check the external connector on the proliant to see if you have a LVD or HVD SCSI connector.
HTH!

Low Voltage is compatible with SE SCSI.

Re: Which External SDLT 320 to buy
I am confused, is there a SDLT with HVD interface avialable ? I can only find LVD interface.
The LVD interface is compatible with SE.

Re: Which External SDLT 320 to buy
The SDLT320 can run 80MB/Sec burst. HVDS SCSI is limited to 40MB/Sec.
You don't want a SE controller to an LVDS drive, since it's limited to 40MB/Sec and less cable length.
Also, I think all the SDLT drives are native LVDS, and would require a converter board to make an HVDS drive (another thing to fail).

Re: Which External SDLT 320 to buy
That's the native (uncompressed) rate - it can run at least 32MB/sec with compressed data (not sure at what point the compression engine limits). The interface burst rate is 80MB/sec, which is the rate you can write to the drive's buffer. Even though the drive can sustain about 32MB/sec to the tape, the faster burst rate helps in keeping the drive streaming when the host rate varies.

Re: Which External SDLT 320 to buy
not to nitpick, but the compressed rate is only a measure of how much native data on the system is being backed up. The actual amount of bytes transfered to the tape never exceeds 16MB/s
for instance if you had a 32MB file on the server, it would theoretically be transferred over in 1 second. But it would be compressed into a 16MB chunk first.
