Page 36: The Power Hypervisor And Virtual I/O Server Technologies
This requires an attached HMC with the proper level of software to control the system resources and an updated system firmware level to electronically isolate systems resources. Dynamic LPAR support varies by Linux distribution. IBM eServer OpenPower 710 Technical Overview and Introduction... - Page 37 Note: Dynamic logical partitioning is supported by SUSE 9 and RHEL AS 4 or later. Changing memory attributes dynamically is not supported at the time of writing. Micro-Partitioning technology The OpenPower 710 POWER Hypervisor, when enabled, provides Micro-Partitioning virtualization technology. With Micro-Partitioning, a partition may be defined with a processor capacity as small as 10 processor units.

HMC, as well as general network access. Note: It is recommended to use separate adapters for the management and the public LAN to protect access of your system’s management functions. IBM eServer OpenPower 710 Technical Overview and Introduction... - Page 41 Each LPAR requires at least one physical processor if virtualization is not used. Based on this, the maximum number of dynamic LPARs per OpenPower 710 server is two without virtualization. With the use of the IBM Advanced POWER Virtualization, the number of partitions per processor is 10.
- Page 42 For the OpenPower 710 server, additional disk space can be provided by using an external storage subsystem such as the IBM 2104 Expandable Storage Plus. For more detailed information of the available IBM disk subsystems, refer to “External disk subsystem” on page 25.

L1 and L2 caches and L2 and L3 directories on the POWER5 chip are manufactured with spare bits in their arrays that can be accessed via programmable steering logic to replace faulty bits in the respective arrays. This is analogous to the redundant bit-steering employed in main storage as a mechanism that is designed to help avoid physical repair, and is also implemented in POWER5 systems. -
