IBM DS8000 - Manual (Page 161)

Chapter 7. Copy Services 139
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.
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.
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.
