HP Unveils Scale-Out Computing Hardware For Data Centers

The ProLiant SL server line is a lightweight, power-efficient modular computing system for companies with large data centers that support cloud computing environments.

Hewlett-Packard 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.

Cloud computing is a type of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Companies operating such environments include Google, Amazon, and Salesforce.com. Small and midmarket companies are particularly interested in running applications on vendors' cloud computing environments in order to avoid building large IT infrastructures.

HP, Intel, and Yahoo last year launched the Open Cirrus cloud computing test bed with a goal of promoting collaboration among businesses, government agencies, and colleges and universities. More than 50 research projects are plugged into Open Cirrus.
