IBM Tivoli SAN Manager supports the viewing of Cisco’s VSAN.

A new level of VSAN management has been inserted into the IBM Tivoli SAN

Manager hierarchy. The new features include:

򐂰 Cisco MDS 9000 Support

򐂰 Out of band discovery of Cisco Fabric using Cisco MIBs

4.4 IBM TotalStorage Multiple Device Manager

The Multiple Device Manager is software that has been designed to enable

administrators to manage SANs and storage from a single console. This

software solution is designed specifically for managing net worked storage

components based on the SMI-S, including:

򐂰 IBM TotalStorage SAN File System

򐂰 IBM TotalStorage SAN Integration Server

In a SAN environment, multiple devices work together to create a storage

solution. The IBM TotalStorage Multiple Device Manager software product

provides integrated administration, optimization, and replication features for

interacting SAN devices, including the IBM TotalStorage SAN Volume Controller,

IBM TotalStorage SAN File System, IBM ESS, and IBM FAStT devices. The

multiple device management layer provides an integrated view of the underlying

system so that administrators can drill down through the virtualized layers to

easily perform complex configuration tasks and more productively manage the

SAN infrastructure. Because the virtualization layers (as well as IBM ESS

products) support advanced replication configurations, the Multiple Device

Manager product offers features that simplify the configuration, monitoring, and

control of disaster recovery and data migration solutions. In addition, specialized

performance data collection, analysis, and optimization features are provided. As

the SNIA standards mature, the Multiple Device Manager view will be expanded

to include CIM-enabled devices from other vendors, in addition to IBM storage.

The Multiple Device Manager product provides support for configuration, tuning,

and replication of the virtualized SAN. As with the individual devices, the multiple

device management layer is open and can be accessed via a GUI, CLI, or

standards-based Web Services.

IBM TotalStorage Multiple Device Manager consists of three major components:

򐂰 Device Manager

򐂰 Performance Manager

򐂰 Replication Manager

Figure 4-35 on page 193 provides an overview of the Multiple Device Manager

architecture. It shows the communication flow between supported devices

through the Multiple Device Manager Server and Console. It shows the

components that comprise the Multiple Device Manager and the communication

protocols between the components.
