2010-02-18 Thread Erast

Guys,

just to let you know that Nexenta was working for quite some time on its 
COMSTAR VTape driver. It is now beta ready and feature complete as far 
as code is concerned:


http://www.nexentastor.org/projects/vtape

It requires b131+ to compile and run. Tested with NexentaStor and with 
many Backup vendors - results are very good.


Yes, we hope to push this into OpenSolaris code base at some point and 
looking for Beta users.


Originally code was contributed by Sumit Gupta, who is a well-know 
COMSTAR creator and former Sun's rock star! So, we sure that from design 
perspective our implementation is the best.


Give it a try people!

There is a project at Kenai (for the moment):
http://kenai.com/projects/stmfssd that I believe Marc is referring to.

I was somewhat hesitant about announcing it here due to uncertain
Kenai future (thank you very much, Oracle), but I guess there is no
real reason to keep silence.

So, yes - the project aims creating virtual tape based on COMSTAR.
Pretty much as Marc said it is in the early stage and contributions
are very welcome.

Erast,

That's pretty awesome...I have it up and running already!

It looks like drive type personalities are missing, though? That's pretty
important for folks running traditional backup software (NetBackup, TSM,
etc).

Also, does it work over FCP too?

Thx!

It just simulates a generic Tape interface. It seem to work with Solaris and 
Linux initiators. I think Nexenta did some limited testing with Netbackup and 
it was able to identify the tape drive.

I have not tested it with FC. FCP CONF and FCP-2 error recovery are not there 
in stt. But I don't know if that will impact basic tape functionality. It will 
be interesting if someone can give that a try.

I think you really need to get SCSI autochanger support into it...otherwise
its use-case is somewhat limited with traditional backup software, no?

Is that on the roadmap?

I did manage to connect the initiator to an XP machine via iSCSI, but the
device isn't recognized as a Removable Device.

Thx.

Re: [storage-discuss] Open Source VTL

2010-02-18 Thread Sumit Gupta

I think unlike Linux and Solaris, windows require every Tape Vendor to provide 
their own driver or some sort of a shim which then can use the default windows 
tape driver functionality.

For the autochanger or VTL roadmap, Nexenta guys can provide more insight into 
their plans. I looked into the SMC spec once and it felt that to do a full VTL, 
it will take much more than just the SCSI medium changer part. There is quite a 
bit of sing and dance that needs to go between the slots, media and the tape 
drives because these are different LUs that now need to talk to each other 
outside of the COMSTAR's LU provider interface. But still if there is an 
opensource project around it, I can certainly help out.
