IBM® System Storage™ Resiliency
Family is a set of products and features that are designed to help you implement
storage solutions to keep your business running 24 hours a day, 7 days a week
by providing data duplication, data migration, and disaster recovery functions.
These products and features are available on the IBM System Storage DS6000™ and IBM System Storage Enterprise
Storage Server® Models 750 and 800. There are a number of advanced Copy
Services functions that are part of the IBM System Storage Resiliency
family and are supported across various server environments such as zSeries®, pSeries®,
System i and servers from Sun and Hewlett-Packard.
The following IBM
System Storage Copy
Services functions are available as optional features:
- Point-in-time copy, which includes IBM System Storage FlashCopy®
- Remote mirror and copy, which includes the following functions:
- IBM System Storage Metro Mirror (previously
known as Synchronous PPRC)
- IBM System Storage Global Copy (previously
known as PPRC Extended Distance)
- IBM System Storage Global Mirror (previously
known as Asynchronous PPRC)
You can manage Copy Services functions using any of the following methods:
- IBM System
Storage™ DS CLI (command-line
interface)
- IBM System
Storage DS Storage Manager (Web-based
interface)
- DS API (application programming interface)
- Host I/O commands from zSeries servers
- Failover and failback operations: In a planned or unplanned outage,
such as a disaster, you can use failover and failback operations, which use
Copy Services features to reduce the time that is required to synchronize
remote mirror and copy volumes after switching between sites. (A failover
operation is the process of switching production to a remote site. A failback
operation is the process of returning production to its original location
after a disaster.)
