IBM TotalStorage Productivity Center for Replication
IBM TotalStorage Productivity Center (TPC) for Replication V3.1 provides optional management of DS6000 series business
continuance solutions, including FlashCopy and Remote Mirror and Copy functions. IBM TPC for Replication Two Site BC V3.1
also provides disaster recovery management support in a two-site DS6000 configuration. This management support is available
with the IBM TPC for Replication software program (purchased separate from the DS6000 series).
IBM System Storage FlashCopy
IBM System Storage FlashCopy is designed to provide a point-in-time copy capability for DS6000 series logical volumes.
FlashCopy creates a physical point-in-time copy of the data, with minimal interruption to applications, and makes it possible to
access both the source and target copies immediately. FlashCopy is an optional capability, and is available with the point-in-time
features on the DS6000 series.
Remote Mirror and Copy Solutions
The D6000 series supports several hardware-based remote mirror and copy solutions. They are optional capabilities on the
DS6000 series and are available with the remote mirror and copy features on the DS6000 series. IBM supports the following
remote mirror and copy solutions. Refer to Table 3 for DS6000 series model support and LMC prerequisites. The DS6000 series
system can participate in remote mirror and copy solutions with the Enterprise Storage Server (ESS) Model 750, ESS Model 800,
and DS8000 series systems.
IBM System Storage Metro Mirror
Metro Mirror is designed to provide real time mirroring between two systems that can be located up to 300 km from each other. It
is a synchronous copy solution where write operations are completed on both copies (local and remote site) before they are
considered to be done.
Extending distances beyond 300 km is also possible however, due to network configuration variability, the customer must work with
the channel extender vendor to determine the appropriate configuration to meet their performance requirements. IBM support
approval for these longer distances can be requested by submitting a Request for Price Quotation (RPQ). The RPQ should include
information on distance between sites, the channel extension technology, the type of telecom line, the amount of network
bandwidth, the DS6800 system capacity, and a general description of the workload.
IBM System Storage Global Copy
Global Copy is a non-synchronous long-distance copy option for data migration and backup. With a non-synchronous operation,
the distance between the primary and secondary DS6000 series system will have only a minimal effect on the application response
time. Therefore, Global Copy can operate at very long distances.
IBM System Storage Global Mirror
Global Mirror is a high performance, asynchronous remote-mirroring copy solution. It is designed to provide a two-site disaster
recovery and backup solution at virtually unlimited distances.
Since the distance between the primary and secondary DS6000 series system has little impact to host applications at the primary
site, the remote site can be located at distances from the local site well beyond those supported with Metro Mirror. The distances
are typically limited only by the capabilities of the network and channel extension technologies.
