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.
