Intel Xeon E5507 Nehalem-EP 2.26 GHz 4 x 256KB L2 Cache 4MB L3 Cache LGA 1366 80W BX80602E5507 Server Processor

The Quad-Core Xeon E5507 processor, with advanced features like ECC memory support and Virtualization Technology for Directed I/O, is built to handle the ever-changing demands of a virtualized and consolidated computing environment.

• ECC Memory SupportWith the integrated DDR3 memory controller, the Intel Xeon 5507 processor enables three channels of ECC DDR3 memory, resulting in up to 19.2 GB/sec memory bandwidth.
• Intel Virtualization Technology (VT-x)Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.
• Intel Virtualization Technology for Directed I/O (VT-d)Intel Virtualization Technology for Directed I/O (VT-d) extends Intel’s Virtualization Technology (VT) roadmap by providing hardware assists for virtualization solution. VT-d continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environment. These inherently helps IT managers reduce the overall total cost of ownership by reducing potential down time and increasing productive throughput by better utilization of the data center resources.
• Intel 64Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
• Execute Disable Bit (EDB)Intel’s Execute Disable Bit function can prevent certain classes of malicious “buffer overflow” attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas of the memory where application code can execute and where it cannot. When a malicious worm attempts to insert code into the buffer, the processor disables code execution, preventing damage or worm propagation.
• Enhanced Intel SpeedStep Technology (EIST)EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production, which means of enabling very high performance while also meeting the power-conservation needs.
