HP StorageWorks Business Copy and H P Snapshot
XP
The optional HP Business Copy (BC) software allows you to make up to nine ongoing
copies of data for nonproduction activities such as backup, batching, and system
testing. HP Business Copy suppor ts HP Snapshot. HP Snapshot is optional software that
creates mul
tiple, point-in-time, online, local copies without impacting primary production
operation. HP Snapshot may require additional shared memory.
HP StorageWorks Continuous Access Synchronous
and HP Continuous Access Asynchronous
The optional HP Continuous Access Synchronous software allows you to make ongoing
synchronous copies of array data to a remote array located many miles away from the
source array.
The optional HP Continuous Access Asynchronous software is similar to HP Continuous
Access Synchronous, but it operates in asynchronous mode. Transactions to be written
to the secondary array are kept in cache memor y on the local a rray in a “side-file.”
This potentially increases performance in remote copying. Copy operations are
sequence-stamped to ensure they are executed and sorted correctly at the remote disk
array.
HP StorageWorks XP Disk/Cache Partition
HP Disk/Cache Pa r tition software can help Enterprise customers subdivide a large XP
disk array into smaller storage segments for accomplishing corporate storage related
initiatives such a s c onsolidation, tiered storage, chargeback, and application usage
tracking. Each domain or par tition is separately configured and managed. Each
partition has its own assigned host ports, disk groups, and c ache. This software can
reduce storage costs by d ividing the disk array into smaller segments suitable for
departmental usage, while retaining superb performance and high availability.
