MSA 2040 Snapshot and Clone:
All MSA 2040 models come STANDARD with 64 snapshots and Volume Copy software (only available on linear
storage).
512 Snapshot option is also available for additional cost.

Software
 HP MSA Remote Snap Software is only available with Linear Storage
 HP MSA Remote Snap Software is array based software that provides remote replication on the HP MSA
2040 Array products. HP Remote Snap is a form of asynchronous replication which consists of replication
of block-level data from a volume on a local system to a volume that may be on the same system or on a
second independent system. This second system may be co-located with the first system or may be
located at a remote site.
 HP Remote Snap functionality is based on existing Snapshot technology offered by HP 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.
 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).
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. 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
