HP Remote Snap functionality is based on existing Snapshot technology offered by HP
P2000 SAN Array products. Snapshots are used to track the data to be replicated as well as
to determine the differences in data updated on the master volume, minimizing the amount
of data to be transferred.
HP Remote Snap replication technology provides the ability to accomplish key data
management and protection capabilities. First, because Remote Snap uses snapshots as
the underlying technology it creates multiple local recovery points which can be used for
such tasks as to complement daily backups; second, replication provides the ability to
access data in a remote site which could be used for dispersed operations; and third but
definitely not least important replication allows for business continuance in the event of a
failure on the primary site.
In order to perform a replication, a snapshot of the volume to be replicated is taken, creating
a point-in-time image of the data. This point-in-time image is then replicated to the
destination volume by copying the data represented by the snapshot via a transport medium
such as TCP/IP (iSCSI) or Fibre Channel. The amount of data transferred is minimized
though the use of snapshots whenever possible.

( NOTE: One license per array is required for replication. For example, if you
have two P2000 arrays performing replication (from Primary system to Remote
System), you will need 2 licenses).
Product Features Storage based asynchronous snapshot replication
Initial copy of data can be performed locally, reducing burden on wide area networks
Support of both Ethernet and Fiber Channel interconnects provides flexible options to the
application environments.
Snapshot based replication technology means only changed data will be replicated to
alternate site
Replication Wizard simplifies the task of setting up and establishing replication pairs from
one unified, easy to use GUI.
Snapshot based replication enables both local and remote recovery depending on the need.
Snapshot replication isolates problems to a specific point in time which can be selected by
the administrator. Additionally snapshot replication supports longer distance replication.
Multiple relationships provide greater storage flexibility and utilization.
Bundled 64 Snapshots and Volume Copy integration provides better efficiencies by
combining the management and array technologies to create local copies.
Fast application recovery with minimal or no transaction loss
Creation of disaster tolerant copies of your critical business data
No-single-point-of-failure solution to increase the availability of your customers data
