1. I'm not familiar with the specific devices, but you should probably
be okay with a single dedicated 'backup' HBA.

2. You'll need a SAN Media Server license and SSO license for each media
server you want you backup over the SAN

3. (see above)

4. I have 5-6 Linux SAN Media servers (RH73, CentOS3 & CentOS4) - they
work great.

Subject: [Veritas-bu] SSO Options

 

All,

 

We're running 5.1 MP4 on Windows and UNIX (Solaris 2.8) here, and with
all the budget money flying around I'm looking into adding the SSO
Option.  Basically, I would like to add our ATL to the SAN Switch and
have our larger capacity file and database servers then SSO themselves a
free drive and write directly to it.

 

Essentially replacing

 

SAN (DATA) --> Client --> 1GB Nic --> Media Server --> (SCSI) ATL/DRIVE#

 

with

 

SAN (DATA) --> Client --> SAN --> ATL/DRIVE#

 

I have a few questions.

 

#1 - Does running both the Storage Device (Hitachi AMS 500) and SSOing a
drive on in the ATL affect performance?  I'm assuming I can easily drive
our SDLT220 drives to capacity using this method, but should I use two
HBAs? (I'm assuming no.)

 

#2 - Does every server that wants to "grab" a drive need a media server
license?  I would only be using these servers daily to run their own
backups - not others.  Is this that SSO Media Server license I hear
mentioned every once and a while?

 

#3 - What's involved in upgrading my regular old Master / Media servers
to SSO (from a software perspective?)  Do I have to upgrade everything
to SSO, or simply add a few new SSO Media servers to my current setup?

 

#4 - Does anyone run SSO on Redhat Linux AS 3?  Several of our larger
databases are now Oracle on Linux.

 

Thanks all!

 

-Jonathan
