A
allows an administrator to restart a server without having to visit it in person, saving travel time and getting the server back up and running quickly and securely. It also adds new features to those provided by IPMI 1.5, including VLAN support, Serial over LAN, enhanced authentication and encryption algorithms (RMCP+ and AES) and a firmware firewall.

| With the Xeon 5500 and 5600 Series processors, Intel has diverged from its traditional Symmetric | ||
|
| Multiprocessing (SMP) architecture to a | ||
|
| processors are connected through serial coherency links called QuickPath Interconnect (QPI). | ||
|
| QPI is capable of 6.4, 5.6 or 4.8 GTps (gigatransfers per second), depending on the processor | ||
|
| model. | ||
|
| |||
|
| contains one 12MB L3 cache shared by all the cores. The shared cache is dynamically allocated | ||
|
| among the cores as needed. The multiple cores appear to software as multiple physical | ||
|
| processors. Four- and | ||
|
| speed Xeon processor with 2 cores. | ||
|
| Turbo Boost Technology increases performance by translating the temperature, power and | ||
|
| current head room into higher frequency. It will dynamically increase by 133MHz for short and | ||
|
| regular intervals until the upper limit is met or the maximum possible upside for the number of | ||
|
| active cores is reached. The maximum frequency is dependent on the number of active cores. | ||
|
| The amount of time the processor spends in the Turbo Boost Technology state depends on the | ||
|
| workload and operating environment, providing the performance you need, when and where you | ||
|
| need it. For example, a 2.66GHz | ||
|
| at 2.93GHz. With only one or two cores active, the same processor can run those cores at | ||
|
| 3.06GHz. Similarly, a 2.4GHz | ||
|
| When the inactive cores are needed again, they are dynamically turned back on and the | ||
|
| processor frequency is adjusted accordingly. | ||
