HP Intel Xeon E5503

Product Description

Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple virtual" platforms. It offers enhanced manageability by limiting downtime & maintaining productivity by isolating computing activities into separate partitions. Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) & Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security & reliability of the systems & also improve performance of I/O devices in virtualized environments. Intel 64 architecture delivers 64-bit computing on server, workstation, desktop & mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual & physical memory. Idle States are used to save power when the processor is idle. C0 is the operational state, meaning that the CPU is doing useful work. C1 is the first idle state, C2 the second, & so on, where more power saving actions are taken for numerically higher C-states. Enhanced Intel Speed Step Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel Speed Step Technology switches both voltage & frequency in tandem between high & low levels in response to processor load. Enhanced Intel Speed Step Technology builds upon that architecture using design strategies such as Separation between Voltage & Frequency Changes, & Clock Partitioning & Recovery. Intel Demand Based Switching is a power-management technology in which the applied voltage & clock speed of a microprocessor are kept at the minimum necessary levels until more processing power is required. This technology was introduced as Intel Speed Step Technology in the server marketplace. Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses & malicious-code attacks & prevent harmful software from executing & propagating on the server or network. Intel VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel Virtualization Technology platforms reduces the memory & power overhead costs & increases battery life through hardware optimization of page table management.
