Expanding Disk Storage 7

Expanding Disk Storage

This section discusses how to:

• Plan for storage expansion

• Install the additional storage hardware on your system

• Make the additional storage space available to DPM

Planning Additional Disk Storage

As your IT needs outgrow the internal storage standard with your PowerVault

Data Protection Solution, additional disk drives are required. To meet those

needs, develop a plan which considers the requirements for:

• Estimating the additional DPM storage pool capacity

• Determining the appropriate RAID adapter and RAID configuration

• Determining whether to add disk drives internally or externally

• Determining when the system can support hardware installation

downtime

• Using global hot spares

• Installing Dell's systems management tools

Estimating Additional Storage Requirements

The storage capacity must be estimated based on the size of the additional

data sources to be protected and the number of recovery points retained on

the DPM server. Refer to the “Allocating Space for Protection Groups” and

“Planning the Storage Pool” sections of Planning a System Center Data

Protection Manager 2007 Deployment for more info. These sections outline a

methodology for estimating the storage requirements for DPM.

Example: Storage Space Estimation

In this example, the server administrator is protecting two additional servers:

• The first server contains a sales-tracking SQL database.

• The second server is running Exchange Server.
