I have roughly 100TB on xsan, and would like to backup this data onto another san. I'm wondering if there are software out there that does good compression with video files. Allocating another 100TB would be so costly, son wondering how does every backup their data.

Xsan may need to be enabled on OS X Lion clients that were migrated from Mac OS X v10.6 via the Migration Assistant. A migrated system may show fsmpm's status as not running, or may show the computer as unreachable or offline in Xsan Admin on another system such as the metadata controller.

This article contains a script used to configure Promise VTrak SAS-connected Expansion Chassis for Xsan. This script is used in the event that a Promise VTrak RAID Controller has already been configured for use with Xsan, and that an Expansion Chassis is being connected to the already-configured RAID Controller.

Xsan Admin and the file system manager (fsm) for Xsan may exhibit unexpected behaviors such as: Being unable to reach some clients; commands to unmount volumes, add clients, or remove clients take an unexpectedly long period of time; status updates take longer than expected before allowing further user control.
