be on the same system or on a second independent system. This second system may be
collocated with the first system or may be located at a remote site.
• HPE Remote Snap functionality is based on existing Snapshot technology offered by HPE MSA
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.
• HPE 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.
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
• 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 1040 and/or MSA 2040/ 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
