series. (The 2000 series includes 1P and 2P servers; the 6000 series contains highperformance 2P and 4P servers.) The second digit (Y) describes the processor's generation. For example, 61XX describes the 1st generation of the 6000 series. Select HP ProLiant G7 servers use AMD Opteron 6100 series - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 3
cores, that implements an instruction set. AMD and Intel 5500, 5600, and 7500 series processors support some or all of the memory. Intel Xeon processors for 1P and 2P ProLiant servers We use Xeon 5500 and 5600 series processors in HP ProLiant 100 and 300 series servers. The Xeon 5500 series - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 4
of 24 MB. A four-channel integrated memory controller supports up to 16 DIMM slots through four scalable memory buffers (Figure 2). Four-socket ProLiant DL 500-series servers with Xeon 7500 series processors have 64 DIMM slots and support up to 1 TB of memory. The processors use QPI links to connect - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 5
reliability, availability, and serviceability (RAS) features. The Xeon 7500 series processors also come with Intel Machine Check Architecture Recovery. Figure 2.

servers. AMD produces the AMD Opteron 6100 series processor with a 45-nm process. The processor features Direct Connect Architecture 2.0 and contains two dies on a single multi-chip module (MCM) package (see Figure 3). Each die has four or six cores, a dual-channel memory controller-which supports - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 7
to allow addressing to 36 bits. This gives a maximum of 64 GB of physical addressable memory. AMD Opteron and Xeon processors support 32-bit addressing and the 36-bit PAE. As shown in Table 3, the 32-bit instruction set for both the Xeon and AMD Opteron family processors includes: Standard x86 - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 8
numeric support. It also adds new instructions to support 128-bit SIMD integer operations. SSE3 instructions include 13 instructions that the cumbersome and slow nature of the process needed to access the remainder of the memory. The 64-bit extensions give you the benefit of 64-bit addressing at a - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 9
in 4P systems because the processors can communicate directly rather than moving data from one processor to another. The AMD64 architecture uses a Non-Uniform Memory Access (NUMA) design to improve performance with multi-threaded applications. The NUMA design gives each AMD Opteron processor a local - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 10
, Availability, and Serviceability (RAS) features the link in RAS mode decreases, but the link in series processors let QPI buffers enter a sleep state to reduce power requirements of inactive QPI links. ProLiant G6 and G7 servers enable this feature by default. You can change it through the HP - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 11
to run at different frequencies and voltages depending upon computing demand. As a result, PowerNow! can lower server power consumption without compromising performance. Activate it through the BIOS-controlled Dynamic Mode of Power Regulator for ProLiant, which does not require an OS driver. 11 - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 12
from iLO Advanced menus or the HP Insight Control (ICE) management suite. Virtualization In a virtual machine (VM) environment, a software layer known as the hypervisor makes it appear that each guest OS has full control over the server's processor, memory, and I/O devices. Actually, each guest OS - HP ProLiant BL660c | AMD Opteron™ and Intel® Xeon® x - Page 13
