132 IBM CSM to IBM Systems Director Transformation Guide
5.1 SDMC
This section provides a brief description to IBM Systems Director Management Console. It
touches upon the advantages of using it over HMC and IVM. It also throws some light on
high-availability options, and it covers the command line interface of the IBM Systems
Director Management Console.
5.1.1 Overview of SDMC
The IBM Systems Director Management Console (SDMC) is the successor to the Hardware
Management Console (HMC) and the Integrated Virtualization Manager (IVM).
The HMC is designed for management of Power Systems from entry level servers to high-end
systems. Management of entry systems can also be done with the IVM, a function of the
Virtual I/O server.
An HMC can administer up to 256 LPARs, whereas IVM is confined to the system the Virtual
I/O Server is installed on. Moreover, an HMC does not allow the management of Power
processor-based blades.
Figure 5-1 on page 133 shows one HMC (as a machine) managing some Power servers and
an IVM (as a box) managing the whole blade system or only one blade. IVM is installed
normally on one or more blade servers, but it can be installed on entry level Power servers
also. IVM is packaged together with VIO Server as part of PowerVM.
Also see Figure 1-1 in the following publication:

Figure 5-1 on page 133 shows the Management Consoles HMC and IVM managing Power
servers and the Power blades, respectively.

Figure 5-1 HMC and IVM management for the Power servers and the Power blades
With the introduction of SDMC, the need for two different management servers is withdrawn.
It is capable of managing both the Power servers and the Power processor-based blades, as
shown in Figure 5-2 on page 134.
