IBM Midrange System Storage Hardware Guide
The Storage Manager software is now packaged as the following combinations:
򐂰
Host-based
software
– Storage Manager Client (SMclient)
The SMclient component provides the graphical user interface (GUI) for managing
storage systems through the Ethernet network or from the host computer.
– Storage Manager Runtime (SMruntime)
The SMruntime is a Java™ runtime environment that is required for the SMclient to
function. It is not available on every platform as a separate package, but in those
cases, it has been bundled into the SMclient package.
– Storage Manager Agent (SMagent)
The SMagent package is an optional component that allows in-band management of
the DS4000 and DS5000 storage subsystems.
– Storage Manager Utilities (SMutil)
The Storage Manager Utilities package contains command-line tools for making logical
drives available to the operating system.
– Failover driver support
Storage Manager host based software includes an optional failover driver. It is a
multipath driver built on MPIO technology.
– Storage Management Initiative - Specification Provider (SMI-S Provider)
An SMI-S provider is a vendor-specific module that is used so that independent
management software, such as IBM TotalStorage® Productivity Center (TPC), can
manage a vendor device using a standard interface based on the Common Information
Model (CIM) protocol
򐂰
Controller-based
software
– DS4000 and DS5000 storage subsystem controller firmware and NVSRAM
The controller firmware and NVSRAM are always installed as a pair and provide the
“intelligence” of the Midrange System Storage server.
– DS4000 and DS5000 storage subsystem Environmental Service Modules (ESM)
firmware
The ESM firmware controls the interface between the controller and the drives.
– DS4000 and DS5000 storage subsystem drive firmware:
The drive firmware is the software that instructs the Fibre Channel (FC) drives about
how to operate on the FC loop.
The Storage Manager functions are reviewed in detail in 4.9, “Step-by-step configuration” on
page 175.
