to operate at this speed. Currently, only certain 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. 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 signals the chipset to limit memory traffic to the DIMM if the DIMM temperature exceeds a programmed trip point. ProLiant G6 and G7 servers can also use the thermal data to reduce fan speed when memory is idle, which reduces power consumption. If the thermal sensor is absent on a DIMM, a POST message will warn that it does not have a thermal sensor, resulting in higher fan speeds and power consumption. I/O technologies ProLiant SL G6 and G7 server trays have PCIe, serial attached SCSI (SAS), and serial ATA (SATA) I/O technologies. These are serial communication protocols for direct-attached storage devices such as hard drives. Hard drive technologies ProLiant SL G6 and G7 server trays support non-hot-plug SFF SAS, SATA, and solid state drives through an optional HP Smart Array controller and SFF drive cage. HP Smart Array controllers ProLiant SL G6 and G7 server trays support the Smart Array P212, P410, and P411 controllers. Optional battery-backed write cache or flash-backed write cache is available for the Smart Array controller. These cache modules prevent information in the buffer from being lost during an unexpected system shutdown. With a complete system failure, you can move the controller and disks to a different server. After restoring power, the controller will flush the cache out to the disks. With a controller failure, you can move the cache module and disks to a working controller, and flush the cache out to the disks. Serial ATA technology implementation HP 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 HP OS-specific driver that uses the embedded controller. It can use RAID 0, 1, and 1+0 and supports a maximum of two logical drives. The B110i 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 using a seamless procedure that maintains the user data and RAID configuration. Networking technologies SL G6 and G7 servers 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, depending on the NIC: • TCP/IP Offload engine (TOE) for Microsoft® Windows® operating systems improves CPU efficiency. • Receive-side Scaling (RSS) for Windows load balances incoming traffic across all processors in a server. 8
