EMC AX150-Series Integrated Management Software Release Notes

Snapshot management software

The snapshot management software is a storage-system-based software

application that lets you create a point-in-time copy — a snapshot — of a

virtual disk; that is, you determine when the snapshot starts. A

secondary server can then access and use the snapshot for backup

purposes or as a base for temporary operations on the copy of the

production data without changing the source data on the virtual disk.

Before you can start a snapshot, you must allocate the required

snapshot

disk resources

. When the allocation completes, the state of the snapshot

transitions to Ready, which means you can start the snapshot on the

source server and then access the snapshot on the secondary server.

When you no longer require the snapshot's data, you can remove access

to the snapshot. Only after you do this can you stop the snapshot. When

you stop a snapshot, the point-in-time copy ends and the snapshot disk

resources are freed for other snapshots to use. If you do not want to start

another snapshot for this source virtual disk, you can destroy the

snapshot. Destroying the snapshot frees and deallocates the snapshot

disk resources that were allocated when you prepared the snapshot.

Each AX150SC, AX150SCi, AX150, and AX150i storage system ships

from the factory with snapshot management software installed.

Navisphere Storage System Initialization Utility

The EMC Navisphere Storage System Initialization Utility runs on your

management station or attached server. It discovers uninitialized

AX150-series storage systems, lets you assign IP addresses to the SPs on

the same subnet, and set up security for these storage systems.

The Navisphere Storage System Initialization Utility ships on the

AX-Series Server Support CD that is supplied with the storage system.

Navisphere Server Utility

The EMC Navisphere Server Utility runs on each server connected to

your AX150-series storage system. This utility lets you register the server

with your AX150-series storage system. It also allows you to use

snapshots on your servers. It lets you start, stop, access or remove a

snapshot.

The Navisphere Server Utility ships on the AX-Series Server Support CD

that is supplied with the storage system.
