IBM Midrange System Storage Hardware Guide
The
host-based software
consists of all the software components that must be installed on a
host system using the storage subsystem or a management station controlling the server.
The
controller-based software
includes everything required for the components of the storage
subsystem to be managed through a remotely LAN/SAN attached host server or PC.
Host-based software
The host-based software includes the following software components:
򐂰 Storage Manager Client (SMclient):
The SMclient component provides a graphical user interface (GUI) for managing storage
systems through the Ethernet network or from the host server. It has two main
components:
– Enterprise Management: The client can manage multiple storage subsystems in a
storage domain, enabling the user to add, remove, and monitor each storage
subsystem.
– Subsystem Management: The client can manage individual storage subsystems.
The SMclient provides an interface for storage management, based on information
supplied by the storage system controllers. When the SMclient is installed on a
management station, commands are sent to the storage subsystem controllers. The
controller firmware contains the necessary logic to carry out the storage management
requests. The controller is responsible for validating and executing the commands and
providing the status and configuration information that is sent back to the SMclient.
The SMclient is bundled with an Event Monitor that can run in the background and send
alert notifications when critical events occur. The Event Monitor service handles
notification functions (e-mail and SNMP traps) and can monitor storage systems whenever
the Enterprise Management window is not open.
The command-line interface (SMcli) is also packaged with the SMclient and provides
command-line access to perform all management functions.
See 4.6.2, “Storage Manager client” on page 148 for additional details.
򐂰 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
DS5000 storage subsystem. This agent allows management of the storage subsystem
using the same path as the I/O requests coming from the system. The host agent software
receives requests from a management station that is connected to a host server through a
network connection and passes the requests to the storage system controllers through the
Fibre Channel I/O path.
The host agent, along with the network connection on the host server, provides an in-band
host agent type network management connection to the storage system instead of the
out-of-band direct network management connection through the individual Ethernet
connections on each controller. The management station can communicate with a storage
system through any host server that has host agent management software installed. The
host agent receives requests from the management station through the network
connection to the host server and sends them to the controllers in the storage system
through the Fibre Channel or iSCSI paths.
Note: Not all software components are available for all platforms.
