If you are going to implement TSM in a SAN, first you need to know if the TSM Storage Agent is supported in HP an SUN. The Storage Agent is the TSM component wich enables the Lan-Free backup.
There are some considerations about the switchs. If you plan to use LTO Library with McData switchs, there is a special configuration for that, I mean, It4s necessary to buy additional switchs (Mc Data ES-1000) to connect them between the McData Directors and the LTO.
With Brocade Switch there is no problem with LTO Libraries.
