HP Unveils Scale-Out Computing Hardware For Data Centers

Hewlett-Packard (NYSE: HPQ) on Wednesday introduced a lightweight, power-efficient modular computing system for companies with large data centers that support cloud computing environments.

The new HP ProLiant SL server line, the latest addition to the HP ExSO portfolio for scale-out computing, comprises an open 2U chassis, which holds fans and power supplies, and task-specific server nodes that slip into the hardware's rail-and-tray design. The ProLiant SL chassis fits into any standard rack from HP or third parties.

HP is initially making three server nodes available. The first is the ProLiant SL2x170z, which fits two servers in a 1U tray. The servers are designed to support highly dense applications found in high-performance computing and Web front-end environments.

Next is the SL160z, which is designed for large memory-cache apps. The server has 18 dual in-line memory module slots and up to two PCI slots. Finally, the SL170z is built for large storage applications such as Web search and database apps. The server has up to six large form-factor Serial ATA or serial-attached SCSI hard drives.

The new systems are scheduled to be available in July. Pricing will vary according to configuration and order volume. HP also offers management software and services as options for the ProLiant SL product line.
