That makes sense.  

So you just license the TB of storage the device has (the one providing the 
VTL; in your case the PathlightVX)? 

The proposal we got for this was a Sun/StorageTEK solution that involved a 
VTA-1000 from Peak Data with 5TB of "cache" and an IBM SL500 with 4 LTO-3's on 
the backend.  I'm not terribly impressed by their proposal overall but if we 
want to purchase a different solution we have to be able to shoot them down in 
front of the City Commission (I hate working for local government) because they 
are the cheapest by like $150K.  One of senior managers is looking heavily to 
me for the license answers (aside of the usual technical recommendation) but I 
don't have direct access to our approved vendors.

Do you by chance know what they call that license?  I tried looking on 
Symantec's web site and they do not actually list any NBU licensing 
requirements with any useful detail.  Just the "Agents and Options".

Thanks.  Huge help (unlike Symantec's web site).

Subject: Re: [Veritas-bu] NBU Licensing Question - Phys. Drives vs. Virtual 
Drives

We're using something like that, an ADIC PathlightVX. It's in front of a 
library with only 2 LTO-3 drives (soon to be 4).

We have 14 virtual drives configured on the PVX (12 of which are going out to 6 
san media servers -- two each --, so they back themselves up across FC). 

It's licensed by the TB, through a VTL license, instead of by virtual tape 
drive.

I think we're only paying for the VTL licenses (8TB) -- for that portion of our 
backup config, the two physical drives on the back end aren't covered, since 
they don't ever touch a media/master, only our PVX.

Hope that made sense..

We got bids in for new back up solutions and one of them proposes 16
virtual tape drives but only 4 physical LTO- 3 drives.  Does anyone know
off the top of their head how that would work?  (Would we need 16 tape
drive licenses to go along with all the clients etc?).  

 

There would not be any addition of media servers or clients.  The
proposal is basically a proprietary SAN set up that has up to 32 VTD
emulation channels to interface with NBU, NBU would not be able to use
it as a DSSU, and NBU will not have direct access to the LTO- 3?s, only
the VTDs.

 

Thanks.
