If you use z/VM and z/Linux this webinar should be very interesting.

Roger Williams, Principal Architect will demonstrate and answer any questions.


ShadowDisk/Z is a software implementation to z/VM which allows multiple Linux virtual machines to transparently share part or all of a virtual Linux file system, without altering the base FS


Key Benefits


        Significantly reduces test/developer disk requirements for multiple-user Linux application testing

        Significantly lessens FS backup/restore requirements, since the DB contains only active FS blocks.

        Databases can be shared among multiple users.

        Utilities provided to query, backup, and restore ShadowDisk/Z databases.

        Provides for the creation of databases which do not require a base FS (NOBASE option).
