Server And Virtualization Management - IBM Power 720 Overview

Note: In the Power 720 system unit SAS bays, only the SAS SFF hard disks or SFF SSDs
are supported internally. Any 3.5-inch HDD or SSD can be attached to the Power 720 but
must be located in a EXP12S drawer (FC 5886).

1.13 Server and virtualization management

If you want to implement partitions, a Hardware Management Console (HMC) or the
Integrated Virtualization Manager (IVM) is required to manage the Power 720 and Power 740
servers. Multiple POWER6 and POWER7 processor-based servers can be supported by a
single HMC.
One OS: If you do not use an HMC or IVM, the Power 720 and Power 740 runs in full
system partition mode, meaning that a single partition owns all the server resources and
only one operating system can be installed.
If an HMC is used to manage the Power 720 and Power 740, the HMC must be a rack-mount
CR3, or later, or a deskside C05 or later.
In 2012, IBM announced an HMC model machine type 7042-CR7. Hardware features on the
CR7 model include a second disk drive (FC 1998) for RAID 1 data mirroring, and the option of
a redundant power supply. At the time of writing, the latest version of HMC code was
V7R7.7.0 (SP1). This code level also includes the new LPAR function support, which allows
the HMC to manage more LPARs per processor core. A core can now be partitioned in up to
20 LPARs (0.05 of a core).
Several HMC models are supported to manage POWER7+ processor-based systems. Model
7042-CR7 is the only HMC available for ordering at the time of writing, but you can also use
one of the withdrawn models listed in Table 1-20.
