DLT 8000

Hi

Im having problems with the installation of a DLT 8000 drive on my windows 2003 server.
Windows will not recognize the devise. It is as if it is not connected at all. Which SCSI interface should I use? I am using a PCI card connected to the motherboard instead of connecting the tape directly to the motherboard.

Regards

Greenda

Re: DLT 8000

Find out if your DLT8000 External drive is a Differential one for which it must have a Differential SCI adapter on your Windows end. It is likely your Windows PCI SCSI card and/or on-baord SCSI are just Fast wide single ended.

Re: DLT 8000

Hi there.
Better get some info on that drive.
If it is a F/W/D scsi drive, you might need an ADAPTEC 2944 controler.

For a UW you need at least a 2940 UW controler ( ADAPTEC ).

At least the controler should have a bandwidth of 40 MB /sec.

Re: DLT 8000

Thanks , For the info ,

The product number of my drive is C6379A so it must be FWD. But this SCSI type supports transfer rate of 20MB/s. Do you think the ADAPTEC 2944 will suit my needs or should i choose an adapter with higher data transfer?

Re: DLT 8000

The C6379A drive is FWD, so the adaptec 2944 is your only option. 20MB/s is much more than sufficient, since a DLT8000 only has a transfer rate of 6MB/s.

Another question ,

If I remove the cover that is on the back of the tape drive i can see there is a HD68 Female conector. Can I use this conector to conect to a 2940 ADAPTEC contoler using a specific cable..

Thanks

Greenda,
If I remember correctly, the 2940 is Ultra-Wide-Single-Ended(UWSE), which will not work with High-Voltage-Differential(HVD) SCSI.

So, you could connect the 2944 (HVD) card to this, but not the 2940 (SE).

Re: DLT 8000

I recommend the ADAPTEC 29160LP
HP Part Number C7474-60001

Re: DLT 8000

Bob,
that adapter is Ultra160 LVD which is completely incompatable with the HVD drive described. The only adaptec usable is the 2944.

Re: DLT 8000

Josh - that adapter is 'completely' compatible - and it is the opne recommended by HP when using the above mentioned dive (DLT 8000)

Re: DLT 8000

Bob,

The 2940 is only usable for LVD/SE drives, which many of the HP DLTs are. the drive spoken of here is FWD which requires a FWD card. -- the 2944.

Re: DLT 8000

I'm sorry Josh - but if you look at the compatibility link - you will see that the C7474A is recommended on all servers that are housing the DLT80/DLT8000/DLT40/80 drives
The C7474A is an ADAPTEC 29160LP - trust me I know it works and is completely compatible - I have one right here in our lab

Re: DLT 8000

Bob,

The Reason that the C7474A is recommended on those servers, is because many of the DLT Drives are LVD/SE. I administer a Netserver that has one of these drives in it.

That being said, the C6379A that Greenda is speaking of in this thread has an HVD interface. I have personally connected this exact same drive to an Ultra160 SCSI card from HP and the device was not recognized. The Adaptec 2940 is an HVD card, and is the ONLY way to connect to an HVD device. HVD is not compatable with any other type of SCSI.
