Ethernet's inherent ability to support concurrent server data transfers on the network enables a client server to restore data from its own
logical volume without impacting other restore operations that may be occurring at the same time on other servers.
From the LEGATO NetWorker backup software users can easily view Storage Concentrator
logical volumes to conduct backups of server-attached storage and also restore that data from the IP SAN
logical volumes to the server-attached storage disks.
While this improved performance, it brought back one of the big challenges associated with
logical volume managers: loading, maintaining and qualifying software on each server.
The new 100-gigabyte LUN would have four I/O stacks to use when reading and writing to the
logical volume, which increases disk performance.
Once connected, each jukebox appears as a single
logical volume to the host for storing user data.
The Tandem and Digital divisions of Compaq have long-standing agreements with Veritas for its equivalent Unix-based
logical volume management software, which will also be supported by the APIs.
