Abstract The HP ProLiant SL6000 Scalable System implements an entirely new mechanical design and architecture in the industry-standard server market. The SL6000 server family is optimized for extreme scale-out computing applications such as High Performance Computing, large-scale enterprise server deployments, and the latest web and cloud computing applications. HP expertise in design and technology implementation in the SL6000 system led to achieving a record-setting performance in the

The chassis supports two server trays of the same model within an SL6000 chassis. To optimize air flow, if one server tray is removed for maintenance, fan speeds increase to ensure adequate cooling of the other tray. If a server tray is removed and a repla

HP ProLiant SL2x170z G6 server The HP ProLiant SL2x170z G6 server tray is optimized for compute power and density (Figure 7). It contains two SL170z G6 server nodes side-by-side in the tray. This means it has up to four sockets for Intel Xeon 5500 Series processors and 32 slots for DDR3 memory modules (eight per processor). Each server node has its own embedded SATA controller that accesses one of the two LFF, SFF, or SSD SATA storage drives housed in quick-release carriers. More detailed

Because two server nodes are installed side-by-side, the front of the unit has twice as many ports and LEDs as the SL170z G6 server. Each server node has its own video and serial connectors, USB ports, NIC ports, health and UID LEDs, optional out-of-band management LAN port, and a slot for an optional PCIe 2.0 x16 adapter (Figure 8).

QuickPath Interconnect controller Intel Xeon 5500 Series processors attain their performance potential through Intel QuickPath architecture (Figure 10). High-speed, point-to-point interconnects directly connect the processors with one another. Intel QuickPath architecture also connects each processor to distributed shared memory and to the I/O chipset. Figure 10.

Turbo Boost technology Intel Turbo Boost Technology complements Hyper-Threading by increasing the performance of both multi-threaded and single-threaded workloads. For workloads and applications that do not benefit from multi-threading, Turbo Boost Technology can increase performance. Turbo Boost is engaged by enabling the Turbo Mode option in the Advanced Power Configuration submenu in RBSU (Figure 11). It automatically increases the clock frequency of active cores operating below power

Unbuffered and registered DIMMs DDR3 DIMMs are available as both Unbuffered (UDIMMs) and Registered (RDIMMs). Both UDIMMs and RDIMMs support error correcting code (ECC). There are three types of DDR3 memory: • PC3-8500R (RDIMM) —1066 or 800 MT/s data rate, depending on memory configuration and processor • PC3-10600E (UDIMM) —1333, 1066, or 800 MT/s data rate, depending on memory configuration and processor • PC3-10600R (RDIMM) —1333, 1066, or 800 MT/s data rate, depending on memory con

Full AC or DC redundancy requires two power supplies to run the z6000 chassis. If one power supply fails and the remaining power supply can meet power demands of both server trays, both servers will continue to run without interruption. AC redundancy with throttling requires two power supplies to run the z6000 chassis. If one power supply fails and the remaining power supply cannot support the full load of both server trays, the servers will throttle using HP power capping technology so

In a multimode environment, it is important to ensure that planning is completed prior to selecting the right power supply for the desired redundancy mode. Use of the HP Power Advisor is highly recommended for identifying the optimal power supply for each SL6000 configuration. The HP Power Advisor is available online at www.hp.com/go/hppoweradvisor. Management and deployment IT administrators using ProLiant SL6000 Scalable Systems will have different computing requirements. Consequently,
