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
MSA arrays performing replication (from Primary system to Remote System), you will
need 2 licenses).
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. Remote Snap is not supported on SAS models.
Snapshot based replication technology means only changed data will be replicated to alternate site
Many to 1 replication (up to 4 nodes) - primary use case is to replicate from "many" branch offices to
the home office for the purpose of backing up data from the branches
Single controller to single controller replication
Advanced scheduler provides several options to IT administrators for business continuance
Flexible architecture allows remote replication between MSA 2040 and/or P2000 G3 supported
arrays. Protects existing investments and enhances business continuity planning objectives.
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
