We have Two Brocade 24 port SAN Switch and 12 Clients and One tape Library ,One Master Server with Media Server.
In Current Schenarion,Tape library is connected to master Server(Media Server) and all clinets are communicating over LAN.
Now I want to introduce SAN Switch to increase Throughput and to established communication over fc.
how Can I achieve the same?
Yes, you can - you will need a Linux media server with a compatible Qlogic HBA from the list https://origin-download.veritas.com/resources/content/live/OSVC/100032000/100032807/en_US/nbu_80_hcl... and liceses to enable the SAN Client functionality which is part of the Enterprise Client license.
Your PLATFORM BASE COMPLETE EDITION 7.6 will allow you to deploy any agent/option, BUT I do not recommend that you attempt to configure FT Media Server / SAN Client on an old NBU version that is no longer supported.
It is expretemely important that you check NBU HCL for supported OS and supported HBA's for FT Media Server.
Even with all compatibilities confirmed, I have seen users running into issues.
If you experience problems, you will have no support, as NBU 7.6.x ran out of support quite some time ago.
Sorry you have mentioned you have clients installed with some Emulex HBAs but never metioned OS of your Master and Media.
Now when you have specified you have Windows-based media server, I can confirm you will not be to use SAN Client feature in this configuration, you will need a Linux-based media server with supported OS and HBA as per the link I posted above.
Please go to this section of the HCL:
Important to distiguish between the clients (SAN Clients) and the media server (Fibre Transport Media Server).
All Clients with all HBAs are supported.
For FT Media Server, only certain Linux and Solaris Media servers are supported, and only with certain QLogic hba's.
Your other option is to configure some of your larger clients as SAN Media servers.
Herewith an explanation of difference between SAN Client and SAN Media server:
For SAN Media server, you need to add the clients as SERVERs on NBU master, uninstall NBU Client software, install NBU media server software (use same Capacity license as on master), zone tape drives to these servers, then re-configure the drives as shared (SSO).
It is not advisable to convert ALL clients to SAN media servers, as only one server at a time can write to a tape drive.
If you have more (SAN) media servers than tape drives, backup jobs will queue and you may run out of backup window.
With multiplexing, multiple (standard) clients can be backed up across the network to the same tape drive simultaneously.
