ISS Technology Update Volume 8, Number 5 Disabling processor cores in Intel®-based HP ProLiant G6 servers HP ProLiant G6 servers with the 4-core Intel Xeon® processor 5500 series have many new power and efficiency features. Several of these features are configurable, letting system administrators tune individual servers to provide optimal performance per watt for specific application environments. One such user-configurable feature is the option to disable individual cores within these processors.

ISS Technology Update Volume 8, Number 5 When to disable processor cores While disabling cores may seem counterintuitive to delivering higher performance, there are at least three situations in which disabling processor cores can prove beneficial. Reducing power use. Disabling processor cores reduces processor power use.

ISS Technology Update Volume 8, Number 5 Accelerated iSCSI application examples Administrators can consolidate storage, enhance manageability, and enable iSCSI boot (also called ‗boot from SAN‘). HP Accelerated iSCSI Licensing Pack for 1GbE network adapters NC373F, NC373T, and NC382T option kits have always included Accelerated iSCSI as a standard feature.

Therefore, for directly attached storage configurations, there is currently no performance benefit to using 6-Gb/s SAS drives attached to 6-Gb/s-capable disk controllers. Interoperability of 6 Gb/s drives with 3 Gb/s drives Six-Gb/s SAS drives are completely interoperable with 3-Gb/s drives.
