Rack-Mounted HMC Enables Control and Management of IBM POWER Processor-Based Servers

The IBM Hardware Management Console (HMC) is updating its underlying appliance hardware to stay current with updates in hardware technology. The 7042-CR6 system is being replaced with the 7042-CR7.




HMCs now offer a high-availability feature. The new 7042-CR7, by default, includes two hard drives with RAID 1 configured. If you prefer not to have RAID 1 enabled on the HMC, you can override it in the ordering system and remove the additional HDD from the order.


RAID 1 is also offered on both the 7042-CR6 and the 7042-CR7 as an MES upgrade option.


RAID 1 uses data mirroring. Two physical drives are combined into an array, and data is striped across the array. The first half of a stripe is the original data; the second half is a mirror (that is, a copy) of the data, but it is written to the other drive in the RAID 1 array.


RAID 1, which requires two physical drives, enables data redundancy.


Blade Management:


The HMC gives systems administrators a tool for planning, virtualizing, deploying, and managing IBM Power System servers.


With the introduction of HMC V7R760, the HMC can now manage IBM BladeCenter Power Blade servers. This includes support for dual VIOS, live partition mobility between blades and rack servers, and management of both blades and rack servers from a single management console.


Removal of Internal Modem:


Future releases of the HMC hardware will not offer an internal modem option.


New Features:

  • Updated browser support: With the release of V7R760, the HMC now supports Mozilla Firefox 7 through 10 and Microsoft™ Internet Explorer 7 through 9.
  • Capacity on Demand enhancements: To better support IBM Pooled Capacity on the Power 795 system, you can now order an unlimited amount of CoD days. The previous limit was 9999.


PowerVM management enhancements:

  • IBM PowerVM and the HMC now support up to 16 concurrent live partition mobility (LPM) activities.
  • You can specify the destination  Fibre Channel port for any or all virtual Fibre Channel adapters during a live partition migration.
  • You can create up to 20 partitions per processor core.
  • During DLPAR add or remove of  virtual I/O adapters to or from a VIOS, the HMC now automatically attempts to run the Add/Remove commands (cfgdev/rmdev) on the VIOS. In earlier releases, you would have to manually run these commands on the VIOS.


Supported Models:


HMC V7R760 is the last release to be supported on models 7310-C04, 7315-CR2, and 7310-CR2. Future HMC releases will not be supported on C04 or CR2.


The Hardware Management Console (HMC) V7R760 is designed to deliver support for:

  • RAID 1, enabling data redundancy  and high levels of performance
  • Power® servers and management of  BladeCenter® power blade servers
  • Up to 16 concurrent live partition mobility (LPM) activities with PowerVM®
  • Latest web browsers
