[ADSM-L] Ang: Re: [ADSM-L] vtl versus file systems for pirmary pool

Not really sure where the general idea that a VTL will limit the number of
available mount points.
I'm not familiar with Data Domain, but generally speaking, the number of
virtual tape drives configured within a VTL is usually thousands. Not sure why
you'd want that many though, I always prefer having a small diskpool infront of
whatever sequential pool I have, and let the bigger files pass the diskpoool
and go straightly to the seq. pool.
As far as for LAN-free, the only available option I know of is SANergy. And
going down that road (concerning both price & complexity) will probably make
the VTL look cheap.
Not sure what kind of licensing you're talking about concerning VTL, but I
assume it's a Data Domain license and not a TSM license?

A couple of things that I did not see mentioned here which I experienced
was.... for Data Domain the VTL is an additional license and it does
limit the available mount points (or emulated drives), where a TSM file
based pool does not. Like Wanda stated earlier depends what you can
afford !
I myself have grown fond of using the file based approach, easy to
manage, easy to configure, and never worry about an available tape drive
(virtual or otherwise). The lan-free issue is something to consider but
from what I have heard lately is that it can still be accomplished using
the file based storage. If anyone has any info on it I would appreciate
it.

What advantage does VTL emulation on a disk primary storage pool have
as compared to disk storage pool that is non vtl ?
It appears to me that a non vtl system would not require the daily
reclamation process
and also allow for more client backups to occur simultaneously.
