Abstract This technology brief describes the key technologies implemented in HP ProLiant 100-series G7 servers based on AMD™ processors. As of this writing, the AMD-based 100-series G7 server platform is limited to the ProLiant DL165. A link to the QuickSpecs for this server is listed in the “For more information” section at the end of this technology brief.

Processor technology The HP G7 AMD-based 100-series servers use the AMD Opteron 6100 series eight- and twelve-core processors, allowing up to 24 cores in a 2-processor, 1 U platform. These processors are based on AMD's 45 nanometer (nm) process and have a core standard wattage of 75W Average CPU Power (ACP). In addition, these processors use Direct Connect™ architecture 2.0, HyperTransport™ 3.0, HT Assist™, and 8x ECC error correction. The 6100 series processors fit into the G34 socket architecture.

superior memory and I/O capability, near native virtualization performance, and a range of power bands 1 that place a priority on low power consumption. Figure 2. Block diagram of Direct Connect 2.
PAGE 5
The G34 socket infrastructure features four, 16-bit HT3 links operating at up to 6.4 GT/s per link. Of the four HT3 links, three are shared processor to processor links and one link on each processor is available for I/O communication. HT Assist HT Assist reduces cache coherence traffic on the HT links. By tracking where data is stored in cache and guiding the processor directly to the caches of other processors, HT Assist reduces cache probe traffic between processors, especially in 4- socket servers.

Low-voltage DDR3 Customers can take advantage of the HP low voltage (LV) DDR3 memory option. LV memory can operate at 1.35 V, reducing power and cooling requirements. Some LV DIMM configurations can affect performance. The difference occurs in 2 DIMM per channel (DPC) configurations with dual-rank DIMMs. In these configurations, the memory bus runs at 1.5 V with 2 DPC at 1333 MT/s, or 1.35 V with 2 DPC at 1066 MT/s. This results in a 20% reduction in bandwidth for the lower voltage.

 Two quad-rank DIMMs per channel results in eight way bank interleaving  Two dual-rank DIMMs and one quad-rank DIMM results in eight way bank interleaving (in servers using three DIMMs per channel) Memory channel interleaving With memory channel interleaving, data is transferred by means of alternate routing through the two available memory channels.

HP Smart Array and SAS/SATA technology The newest serial PCIe 2.0-capable Smart Array controllers use SAS technology, a point-to-point architecture in which each device connects directly to a SAS port rather than sharing a common bus as parallel SCSI devices do. Point-to-point links increase data throughput and improve the ability to locate and fix disk failures. More importantly, SAS architecture solves the parallel SCSI problems of clock skew and signal degradation at higher signaling rates.
PAGE 9
The SAS-2 specification is compatible with both Serial SCSI and Serial ATA protocols for communicating commands to SAS and SATA devices. SAS-2 compliant controllers are fully compatible with 1.5-Gb/s and 3.0-Gb/s SATA technology. For the most up-to-date listing of HP Smart Array controllers that support the SAS-2 specification, see the Smart Array controller matrix: http://www.hp.com/products/smartarray HP Smart Array controllers based on PCIe 2.0 The Smart Array PCIe 2.

NOTE: Smart Array Advanced Pack is not available on Zero Memory configurations. Software RAID HP has developed a software RAID solution based on the Smart Array firmware. The Smart Array B110i SATA Software RAID supports the Array Configuration Utility (ACU), ACU-CLI (command line interface), Simple Network Management Protocol (SNMP) agents, and Web-Based Enterprise Management (WBEM) providers. The B110i features an OS-specific driver from HP that uses the embedded ICH10R controller.

 Advanced Capacity Expansion (ACE) automates higher capacity migration using capacity transformation to remove logical drives by shrinking and then expanding them online. Standard drive migration and expansion remain unchanged.  Mirror Splitting and Recombining in Offline Mode breaks a RAID 1 configuration into two RAID 0 configurations. This is similar to a scaled down rollback functionality that requires two disk drives.  Drive Erase completely erases physical disks or logical volumes.

Common Slot power supplies The HP Common Slot power strategy provides power supply commonality across supported ProLiant G7 servers. Three different sized common slot power supplies are available so customers can choose the most effective power supply to match their needs. “Right sizing” power supplies lets you more closely match the power supply to the server power requirements in specific environments, significantly reducing wasted power.

not. Given the same workload, Cool Speed activation will depend on the installed processor model and local environmental conditions. AMD Cool Speed is enabled by default and is not a user option. C1E ™ In G34 based-systems, the Northbridge chipset detects when all of the processor cores are idle and communicates that command to the Southbridge chipset. After the command is sent, the Northbridge and HT links are powered down and the cores go into a deeper sleep state.

 Alerting capabilities, including basic alert notification for Smart Array drive pre-failure only  Performance monitoring capabilities providing information on processor, memory, disk free space, network utilization, and I/O Remote management LO100i is included in all ProLiant 100-series G7 servers. LO100i represents the core embedded management functions in ProLiant ML, DL, and SL100-series servers.
