When you need a lot, really a lot of servers

In 1993, HP ProLiant servers based on the x86 architecture first appeared on the market. The ProLiant family was replenished with new rulers as the scope of application of such devices grew. Until recently, it was possible to choose: a line of ML - tower servers, which you usually buy by the piece; DL - rack machines for serious tasks, several of which you buy with a large margin for the future; and BL - by filling out a rack with a dozen of such blades, you can always add more to it if requests have increased.

But in recent years, BL and their counterparts have been used even when requests increase tens and hundreds of times - in web search engines, large DBMS and scientific supercomputers. And although the design of these servers uses various technologies that reduce energy consumption and compact placement of internal components, nevertheless, when operating complexes of several thousand computing nodes, even small power savings and size reduction at the level of a single server would have a significant economic effect.

Therefore, HP specifically developed the HP ProLiant SL6000 line , in which, instead of the standard rack-mount case, a new form factor has been applied. Our new system uses the z6000 dual-unit chassis, in which several servers serve common power supplies and fans . Compared to conventional single-node servers, power consumption is reduced by 28%, and the total weight of the server rack - by 31%. A similar solution is used in the BladeSystem chassis for the BL line, but the z6000 does not have a common backplane, thereby improving air cooling inside the chassis.

As with the other sixth generation HP ProLiant systems, depending on the hardware configuration of the z6000, you can use three power supply models: 460, 750, and 1200 watts. To simplify the deployment of large configurations, five SL6000s can be installed in one 10-unit bulk rail kit.

The z6000 has three types of ProLiant SL single-unit dual-processor server modules based on the Xeon 5500:

• The HP ProLiant SL170z is designed for data storage applications. For example, for search engines and DBMS. It accommodates 6 full-size SAS / SATA drives and 16 DDR3 SIM memory modules.
• HP ProLiant SL 2x 170z is designed for supercomputer calculations and maintenance of front-end web applications. In width, it occupies half of the 19-inch rack, so four SL2x170z modules are installed in the z6000 dual-unit chassis, which doubles the placement density of processor power compared to conventional single-unit servers. This model also supports the installation of 16 DDR3 SIM memory modules, but it can accommodate only one 3.5-inch hard drive.
• HP ProLiant SL160z , designed to work with applications associated with intensive use of RAM (for example, caching web-pages), equipped with 18 slots for memory modules and two PCI slots. It can install two 3.5-inch drive.

HP ProLiant SL165z modules based on the AMD Opteron 2400 Series will also be available soon.

All four models are equipped with a dual-port Gigabit Ethernet adapter and support DCMI and IPMI control with individual server chassis modules turned off.

It remains only to sincerely wish everyone to grow your tasks to such an extent that expanding the fleet of servers will mean purchasing several more HP ProLiant SL6000 cabinets! :)
