Hello everyone:

I just wanted to solicit some advice as to how to proceed deploying SSO in the 
following environment.  Any comments from anyone actively supporting a similar 
configuration would be more than welcome.

Here's the scenario:

1.  Customer currently has Brocade 2800 switch with no zoning.
2.  Customer has 6  WIN2K hosts with Emulex HBA's attached to Brocade.
3.  Customer has Compaq EVA Array attached to Brocade.
4.  Customer has existing STK L700 with 6 DLT8000 Drives.
5.  Will be installing Crossroads 10K and HVD SCSI attaching L700 Robot & 
drives to Crossroads 10K & to Brocade.
6.  Customer only has a single HBA in each WIN2K host and wants to use the 
single HBA in each WIN2K host to attach to both existing Compaq array and L700 
via Crossroads 10K.

7.  Customer will be using Veritas NetBackup DataCenter v4.5 with Shared 
Storage Option to dynamically allocate DLT8000 drives among the six WIN2K hosts 
for backup.


Do you see any "gotchas" in deploying this scenario?

Should we establish a seperate zone and or fabric strictly for tape?

Should we be using a dedicated HBA just for tape?

Are there going to be any difficulties using the same HBA for both tape & disk 
with no zoning?

Are there issues with short packets (disk) and long packets (backup) happening 
on the same HBA?

Please let me know your thoughts regarding this configuration.

Thanks in advance,
