HP ProLiant BL660c Innovative technologies in HP ProLiant Gen8 servers - Page 4

Core Microarchitecture Sandy Bridge. Xeon E5-2600 series processors in our ProLiant Gen8 servers have two, four, six, or eight cores that operate from 60 W (Xeon LP) to 135 W. These processors feature an integrated northbridge and memory controller. The processors work with Registered (R) DIMMs, Unbuffered (U) DIMMs, Low-Voltage (LV) DIMMs, and Load-Reduced (LR) DIMMs. Table 1 summarizes the features of Xeon E5-2600 processors used in ProLiant Gen8 servers. Table 1: Intel Xeon E5-2600 processors Intel Xeon E5-2600 Cores 2, 4, 6, 8 L1/L2 Cache 32 KB / 256 KB L3 Cache 2.5 MB/core Direct Media Interface (DMI) x4 PCIe Gen2 speed QuickPath Interconnect links 2 DDR3 Memory controller (Channels/ DIMMs per channel) 4 Ch / 3 DPC Memory supported RDIMMs, UDIMMs, LVDIMMs, LRDIMMs Memory data rates 1600 MT/s Power 60 W-135 W The x4 DMI link is a bi-directional chip-to-chip interconnect between the processor with integrated northbridge and southbridge that handles server I/O functions. The link provides a total of 20 Gb/s in each direction, or 2.5 GB/s per unidirectional lane. This bandwidth is sufficient for SATA, USB, and PCI Express devices. Integrated PCI Express 3.0 lanes connect directly to the processor for increased performance and efficiency. The Xeon E5-2600 processors support 40 lanes of PCI Express 3.0. Xeon E5-2600 series processors support the following technologies: Intel Hyper-Threading (HT) Technology improves processor utilization by letting each core execute two threads simultaneously. QuickPath Technology directly links the processors and I/O chipset with bi-directional, point-to-point QuickPath Interconnect (QPI) links. The QPI links transfer data at up to 8.0 gigatransfers per second (GT/s) with 2 bytes per transfer. This equates to a transfer rate of 16 GB/s in each direction and a total theoretical bandwidth of 32 GB/s. QPI technology has reliability, availability, and serviceability (RAS) features, including self-healing links and clock fail-over. Trusted Execution Technology (TXT) increases protection against software-based attacks to the hypervisor or BIOS and protects against malicious rootkit installations. Advanced Encryption Standard-New Instructions (AES-NI) allows fast and secure data encryption of a variety of applications. Intel Advanced Vector Extensions (AVX) is a 256-bit instruction set extension to Streaming SIMD Extensions for applications that are floating-point intensive. Turbo Boost Technology increases the clock frequency of all active cores when the processor operates below pre-set power and thermal design limits. It complements HT Technology. Intel Virtualization Technology (VT) is a group of extensions to the x86 instruction set that works together to improve virtualization performance in a server's processor, chipset, and I/O devices. 4
