Hi,

I would like to connect an ADIC 100 tape library with LTO-2 tape drives
( SCSI LVD interface ) to a UE 4000 server.

I only found PCI LVD adapters ( options X2222A and X6758A ), but the
I/O board ( X2612 ) in my UE 4000 server is SBus based.

Is there such thing as a SBus LVD SCSI adapter ?

If not : Is there a reliable way to convert LVD to either
HVD / Fiber Channel or iSCSI ?

thanks,

bart

LVD is compatible with SE, it will should autodetect.
Transfer speed will be reduced.

Not as such, however all LVD devices are backwards compatible to SE, so
any SE SCSI cards will work. Only catch is that because it's SE you need
to keep the cable lengths within SE limits, which means max distances of a
few metres.

Oh, I see. But the reason I needed the LTO-2 tape drives was
for the max. speed of 70 MB/s.

Our 'older' LTO-1 are limited to 30 MB/s. ( 100 GB/h )

thanks
Bart.

In that case you will need to back up the E4000 to a PCI based
machine using gigabit ether and then to tape.
I always prefer to use a backup server anyway, by backing up
to the backup server overnight then backing that up to tape
during the day you get 3 major advantages :-
1) The ability to do a fast restore from disk for recent files.
2) No tape changing during a night shift.
3) The ability to automate replacement of a failed root disk by
combining jumpstart with postinstall scripts.

That is exactly our configuration. The UE4000 is the 'backup server'for
40 other systems. During the night we backup the 'clients' to the local
disks on the UE4000. ( +/- 1 TB )
When the disks become full, the savesets are automatically staged to tape.

I am going to take a look at a small SunFire Server ( they come with
multiple gigabit ethernet ports and Ultra160Scsi SE/LVD standard ),
and use it as a 'gateway' to the tape-devices.

Thanks for your advice.

Bart.

Or just put a PCI IO board in the E4000 and then put in a PCI LVD card.

BTDTGTTS. Good move if you can find one.
They are a tad more scarce than hens teeth. Very few were ever sold.
OTOH, acara.co.uk might be worth a phone call.

For those of you just joining us, BTDTGTTS expands to "Been There,

Or just replace the E4000 altoghether with a V240, better performance
and so cheap that you cant afford to wait.

The E4000 will have issues juicing up those fast drives.
The V240 spots quad gigabit ports for all network needs!
