memory controller and lets systems remain stable with more memory modules. You can install three 8 GB RDIMMs per channel for a total of 144 GB if you need large memory footprints. PC3-10600R memory modules can run at 1333 MT/s with two DIMMs per channel and no performance degradation, if you have configured them properly through the RBSU. We fully validate our HP branded DIMMs to operate at this speed. Currently, only some ProLiant SL G6 and G7 server trays using the Xeon 5500 or 5600 Series processors operating at 95W support operating the memory at 1333 MT/s. Use the online DDR3 Memory Configuration Tool for detailed memory configuration guidelines. Fan speed control During POST, the HP BIOS in ProLiant G6 and G7 servers verifies the presence of an integrated thermal sensor on HP DIMMs. The sensor in HP DDR3 modules signals the chipset to limit memory traffic to the DIMM if the DIMM temperature exceeds a programmable trip point. Using the data from these thermal sensors, ProLiant G6 and G7 servers can reduce fan speed while memory is idle. This reduces power consumption. If the thermal sensor is absent, a POST message will warn that the DIMM lacks a thermal sensor, and the fans will run at higher speeds, consuming more power. I/O technologies ProLiant SL G6 and G7 server trays have PCIe, SAS, and SATA I/O technologies. Hard drive technologies ProLiant SL G6 and G7 server trays support non-hot-plug SFF SAS, SATA, and SSD drives through an optional HP Smart Array controller and SFF drive cage. ProLiant SL G6 and G7 server trays support the Smart Array P212, P410, and P411 controllers. Optional battery-backed or flash-backed write cache is available for the Smart Array controller. Serial ATA technology implementation We developed a software RAID solution based on Smart Array firmware to provide RAID support for the embedded SATA controller. The B110i SATA RAID supports the Array Configuration Utility (ACU), ACU command line interface (CLI), SNMP agents, and WBEM providers. You can enable the B110i SATA RAID controller through the advanced section in the RBSU. The HP Smart Array B110i SATA RAID Controller Hot Plug Advance Pack, integrated with SmartStart, provides a license to enable the RAID support on hot-plug models. The B110i includes an OS-specific HP driver that uses the embedded controller. It can use RAID 0, 1, and 1+0 and supports one or two logical drives. The B100i supports up to four 1.5 Gb/s or 3 Gb/s SATA drives. You can also move drives to a hardware-based Smart Array controller in a seamless procedure that maintains the user data and RAID configuration. Networking technologies SL G6 and G7 server trays have an integrated NC362i dual-port, 1 Gb NIC. These servers also support optional multifunction 1 Gb or 10 Gb Ethernet NICs that provide several advantages: • TCP/IP Offload engine (TOE) for Microsoft® Windows® operating systems improves processor efficiency. • Receive-side Scaling (RSS) for Windows load balances incoming traffic across all processors in a server. • iSCSI Acceleration (available on some integrated NICs) offloads some work of creating iSCSI packets from the processor onto the network controller. This frees up the processor for other work. 9
