IBM DS8000 manual Interoperability with ESS, Future Plans

IBM will support IBM TotalStorage Multiple Device Manager (MDM) for the DS8000 under the IBM TotalStorage Productivity Center in the future. MDM consists of software components which enable storage administrators to monitor, configure, and manage storage devices and subsystems within a SAN environment. MDM also has a function to manage the Copy Services functions, called the MDM Replication Manager.

For further information about MDM, see 15.5, “IBM TotalStorage Productivity Center” on page 326.

7.4 Interoperability with ESS

Copy Services for DS8000 also supports the IBM Enterprise Storage Server Model 800 (ESS

800)and Model 750. To manage the ESS 800 from the Copy Services for DS8000, you need to install licensed internal code version 2.4.2 or later on the ESS 800.

The DS CLI supports the DS8000, DS6000, and ESS 800 at the same time. DS Storage Manager does not support ESS 800.

Note: DS8000 does not support PPRC with an ESCON link. If you want to configure a PPRC relationship between a DS8000 and ESS 800, you have to use a FCP link.

7.5 Future Plans

According to the announcement letter, IBM has issued the following Statement of General Direction:

IBM intends to offer a long-distance business continuance solution across three sites allowing for recovery from the secondary or tertiary site with full data consistency.
