Cisco VSAN support
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
–Private
Standard

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
Cisco MDS 9000

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.
