The U.S. Department of Energy (DOE) has awarded us a $7.4 million grant as part of the American Recovery and Reinvestment Act of 2009. The HP Rack and Power Group and the Eaton Corporation will co-develop power and cooling technologies for a fully enclosed IT rack system. Wide acceptance of these technologies can significantly increase...

HP Smart Array optimizes Video on Demand performance
Video on Demand (VOD) is a challenging storage application area because content providers must deliver hundreds of video streams simultaneously and without interruption. The VOD servers that deliver these services require large amounts of relatively high performance disk storage...

... failed drive and the Smart Array controller rebuilds it. During this period, the controller performs multiple disk operations to reconstruct degraded data while it fulfills read requests. This increases latency. Our engineers found that turning RAID Degraded Mode Performance Optimization to ON (Table 3-1) lets the Smart Array controller make greater use of the controller memory for regeneration...

This article describes the features and applications of HP enterprise class solid-state drives (SSDs) and IO accelerators. A subsequent article will detail the differences in these solid-state storage devices based on performance, latency, lifetime writes, and expected life at 100% writes. HP solid-state storage devices are based on NAND flash memory, which is the predominant solid-state...

IO accelerators I/O accelerators are also based on SLC or MLC NAND flash memory technology. Like other storage devices, I/O accelerators present themselves as standard block level storage, allowing applications to access them like other storage volumes. However, an I/O Accelerator is both a controller and storage device, with its own specialized driver that translates standard...
