IBM Intel Xeon Processor X6550 (18M Cache, 2.00 GHz, 6.40 GT/s Intel QPI)

**Hyper-Threading Technology (HT Technology)**

**Today's Intel® Hyper-Threading Technology (Intel® HT Technology) delivers thread-level parallelism on** each processor resulting in more efficient use of processor resources—higher processing throughput—and improved performance on the multi-threaded software of today and tomorrow.

**Intel® Virtualization Technology (Intel® VT)**

**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® 64 Architecture**

**Intel® 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms** when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.

**Enhanced Intel SpeedStep® Technology**

**Enhanced Intel SpeedStep® Technology is an advanced means of enabling very high performance while** also meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load.

**Execute Disable Bit**

**Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and** malicious-code attacks and prevent harmful software from executing and propagating on the server or network. Help protect your customers' business assets and reduce the need for costly virus-related repairs by building systems with built-in Intel Execute Disable Bit.
