HP XP7 Documentation Roadmap (H6F56-96004)

HP XP7 External Storage for Open and Mainframe Systems User Guide
The XP7 External Storage program product enables multiple storage systems to be virtually
integrated. By mapping the logical volumes of other storage systems to an XP7 disk array, External
Storage enables you to operate volumes of multiple storage systems as if you were operating a
single storage system. You can now not only manage and operate the mapped volumes as logical
volumes of the XP7 disk array, but also perform unified data copy operations across other types
of storage. XP External Storage is also useful when you migrate data among storage systems.
HP XP7 for Compatible Parallel Access Volumes User Guide
When you connect to an IBM mainframe, Parallel Access Volumes provides functionality equivalent
to IBM PAV (Parallel Access Volume). PAV allows you to simultaneously issue multiple I/O requests
to one logical device (LDEV) from a host, which improves the data-access speed of the storage
system.
If Parallel Access Volumes is not in use, the I/O requests that a host system can start or manage
is limited to 1 for each LDEV. Parallel Access Volumes, however, specifies the LDEV as an alias
device, and allocates the alias device to the base device. Therefore, all I/O requests to the alias
device are treated as if they were issued to the base device.
HP XP7 Volume Shredder for Open and Mainframe Systems User Guide
Volume Shredder deletes data on a logical volume so that the data cannot be recovered. This
function complies with the DoD 5220.22-M standard of the US Department of Defense, and uses
dummy data to repeatedly overwrite the volume to completely erase the data. In this way, when
the volume is reused, data theft and unauthorized use is prevented.
HP XP7 Cache Partition User Guide
Cache Partition defines a virtual private storage system that has dedicated cache memory for each
application or business. When multiple units of business processing requires different cache
capacities, this function defines a virtual private storage system and allocates dedicated cache
memory to each unit of business processing. After you dedicate cache memory to each application
or business, an increase in load on one server no longer affects the storage resources allocated
to other servers. As a result, you can ensure business continuity while maintaining processing
performance.
HP XP7 Fast Snap User Guide
Fast Snap duplicates storage system volumes within the storage system for open systems. When a
primary volume is updated, only the differential data is saved to the duplicated virtual volume. This
enables you to manage duplication with excellent cost performance.
You can also take backups (snapshot data) of the data that exists in a storage system at a specific
time, and use this snapshot data to recover data if a data failure occurs in the storage system.
HP XP7 for Compatible FlashCopy Mirroring User Guide
Compatible FlashCopy or Compatible FlashCopy SE provides functionality that is equivalent to
IBM FlashCopy and FlashCopy SE. This functionality duplicates data at a higher speed than by
duplicating the execution data from a host.
For a mainframe system, Compatible FlashCopy or Compatible FlashCopy SE duplicates storage
system volumes within the storage system. When a source volume is updated, only the differential
data is saved to the duplicated virtual volume, which allows you to manage duplication with
excellent cost performance.
You can also take backups (snapshot data) of the data that exists in a storage system at a specific
time, and use this snapshot data to recover data if a data failure occurs in the storage system.
