11 Continuous Access XP Journal operations with NAS
Blade
This chapter describes how to use Continuous Access XP Journal with the TagmaStore USP NAS Blade. This
chapter assume you:
• Are familiar with Linux or UNIX computers.
• Have read all of the previous chapters and fully understand the overview, requirements, and restrictions
for Continuous Access XP Journal.
• Have read the HP StorageWorks RAID Manager XP user guide and have a thorough understanding of
RAID Manager XP operations.
• Have read the NAS Backup Restore User’s Guide and fully understand the operations of NAS Blade
systems.
Overview of Continuous Access XP Journal operations in NAS Blade
systems
The NAS Blade system enables integrated management of data in the array. NAS Blade uses the LAN
environment already in place and enables data within an array to be shared across heterogeneous
platforms. You can also use NAS Blade to copy and maintain data stored in the array using Continuous
Access XP Journal’s remote copy feature in the local array. With Continuous Access XP Journal, you can
copy data using the NAS server (even in the remote center), back up data to guard against failures in
primary data volumes, and perform disaster recovery at the primary site.
To use Continuous Access XP Journal in the NAS Blade system, use RAID Manager XP for Linux in the local
array. If you install NAS Backup Restore on the NAS Blade system, RAID Manager XP for Linux is installed
at the same time. You do not need to install the RAID Manager XP included with the local array to the NAS
Blade system.
