Re: [Veritas-bu] IBM Pseries backups over IVE

Just wondering if anyone has done LPAR to LPAR backups of IBM P6-series boxes across the IVE (Integrated Virtual Ethernet). We’ve got a bunch of P570’s coming in the door and what I’m thinking is something like this:

- Each LPAR should communicate to the other LPARs on the same frame via the IVE and never leave the box, this should enable very, very fast LPAR to LPAR communication.

- The NBU licensing is per frame thus could make each LPAR it’s own media server but managing that many media servers adds overhead on my side and making each a media would probably drive up HBA costs.

- So one media per frame backing up the other LPARS on that frame as clients.

- NET_BUFFER_SZ will definitely need to be tweaked, in theory we should be able to get several hundred MB/s per frame.

- I believe this will work without creating any dedicated virtual backup network. Without any special configuration or required interfaces I believe it will know what is local and send traffic appropriately.

Anyone ever configured Pseries backups this way? I have searched far and wide and have not been able to find any BDPs for backing up this hardware.
