Abstract This technology brief describes the key technologies implemented in Intel-based HP ProLiant 100-series G6 servers. The 100-series family includes the ProLiant DL100-series, the ML100-series, and the DL1000 Multi Node architecture. As of this writing, the Intel-based 100-series G6 servers include the ProLiant DL120, DL160, DL180, ML110, ML150, DL170h, DL2x170h, and DL4x170h.
Multi-level caches Xeon 5500 Series processors have a three-level cache hierarchy (Figure 1): • An on-core, 64-kilobyte, Level 1 cache, split into two 32 kilobyte caches: one for data and one for instructions • 256-kilobyte, Level 2 cache for each core to reduce latency •...
Each link is comprised of 20, one-bit lanes. A maximum of 16 bits are used to transfer data; the remaining 4 bits are used for the protocol and error correction. The interconnect performs a maximum of 6.4 gigatransfers per second and has a bandwidth of 12.8-gigabytes per second in each direction, for a total bandwidth of 25.6 gigabytes per second.
Intel Xeon 3400 Series processor technology The Intel Xeon 3400 Series are four core processors used with the Intel 5 series 3400 and 3420 chipsets. The Intel Xeon 3400 series microarchitecture is based on 45 nanometer core technology with an integrated memory controller and PCI Express graphics interface. Xeon 3400 series processors are used in the ProLiant ML110 and DL120 G6 servers.
The ProLiant ML110 and DL120 G6 servers are single-processor platforms which means that the Xeon 3400 Series processors used in these servers do not support the QuickPath architecture found in the Xeon 5500 Series processors. Otherwise, the Xeon 3400 processors support the same architecture found in the Xeon 5500 processors, including distributed shared memory, Intel Hyper-Threading technology, and Intel Turbo Boost technology with Intelligent Power technology.
Memory Xeon 3400 and 5500 Series processors connect directly to memory rather than through a chipset. They support only DDR-3 dual inline memory modules (DIMMs). In the ProLiant 100-series G6 servers, HP manages all processor functionality options, including memory mirroring and memory channel interleaving, through the G6 server BIOS and BIOS Setup Utility (BSU).
• RDIMM configurations can provide larger memory capacity configuration because the memory controller only drives the address and command signals to a single register chip, thereby reducing the electrical load on the memory controller. Users requiring large memory footprints can install three 8-GB RDIMMs per channel for a total of 144 GB.
Memory Mirroring with DDR-3 ProLiant 100-series G6 servers using the Xeon 5500 processor support memory mirroring which protects the system against uncorrectable memory errors that would otherwise result in a system hang or crash. Mirroring occurs when all data is written to both sets of physical memory in channels one and two.
I/O technologies ProLiant 100-series G6 servers incorporate PCI Express, Serial-Attached SCSI (SAS), and Serial ATA (SATA) I/O technologies. PCI Express lets administrators add expansion cards with various capabilities to the system. SAS is a serial communication protocol for direct-attached storage devices such as SAS and SATA hard drives.
The latest Smart Array controllers are compatible with SATA technology and include the following features to enhance performance and maintain data availability and reliability: • SAS and SATA compatibility — The ability to use either SAS or SATA hard drives lets administrators deploy drive technology that fits each computing environment.
Battery backed write cache The BBWC is required for capacity expansion (adding one or more physical disks to an existing array). The controller recalculates parity and balances the data across all the disks. During the expansion, the BBWC preserves data and logical structures on the array. The HP 650 mAh P-Series battery extends battery life up to 48 hours before recharging is necessary.
• RAID 60 allows administrators to split the RAID storage across multiple external boxes. It requires a minimum of eight drives, but only four will be available for data. • Advanced Capacity Expansion (ACE) automates higher capacity migration using capacity transformation to remove logical drives by shrinking and then expanding them online.
servers not supporting Common slot architecture use HP industry standard power supplies. All ProLiant 100-series G6 servers use highly efficient power supplies and DC power regulators to deliver significantly higher power efficiencies. Common Slot power supplies The HP G6 Common Slot power strategy provides power supply commonality across supported ProLiant G6 server lines.
By introducing these different wattage power supplies, HP gives users the option to choose a power supply that meets, but does not exceed, their needs. Oversized and lightly loaded power supplies do not run as efficiently as those that are heavily loaded. Not all ProLiant 100-series G6 servers have Common Slot power supply compatibility, and not all servers will support all available power supply wattages.
Dynamic CPU phase shedding On entry into a low power state (less than 20 W), the Intel Xeon 5500 Series processors will activate the Power Status Indicator (PSI). When PSI is engaged, ProLiant G6 servers turn off voltage regulator phases, thereby saving power and increasing power efficiency.

MHz. This will save power, but may incur some performance penalty. Administrators can configure the maximum memory data rate through the BSU. Managing I/O technologies Disable PCIe 2.0 All ProLiant G6 servers include an option that allows all expansion slots to run at PCIe 1.0 speed rather than PCIe 2.0 speed.
TPM is an option on all ProLiant 100-series G6 servers. For more information about TPM, go to www.hp.com/go/TPM BitLocker Drive Encryption Microsoft BitLocker Drive Encryption (BitLocker) is a data protection feature available in Windows Server 2008. BitLocker uses the enhanced security capabilities of TPM version 1.2 to protect data and to ensure that a server running Windows Server 2008 has not been compromised while the system was offline.
SNMP agents. The agents are included on the ProLiant 100-series model-specific “Easy Set-up” CDs. They are also available at www.hp.com/servers/easysetup. The SNMP agents enable the following capabilities on 100-series G6 servers: • Health monitoring capabilities, including monitoring for drives, fans, network, power supplies, and temperature •...

IPMI 2.0 and DCMI 1.0 ProLiant 100-series G6 servers and LO100i conform to IPMI 2.0 and DCMI 1.0 standards so that customers in heterogeneous environments can manage these servers with either industry standard. The following are basic compliance mandates: • The implementation of all mandatory IPMI 2.0 and DCMI 1.0 in-band and out-of-band commands •...
DL1000 Multi Node server design for scale out computing The HP ProLiant DL1000 G6 Multi Node system is designed for scale out computing in environments where failover is handled at the application level and where hardware redundancy plays a smaller role.

has only one operational power-supply. In this mode, the chassis is expected to survive an unexpected AC power loss to one of power supplies. • Maximum Redundancy (Full AC/DC Redundancy) - Power control logic will maintain a power cap value for the chassis at the DC rating of a single power supply (460W, 750W, or 1200W). If one power supply experiences a DC or AC failure, the chassis should remain on-line and operational.
