HP ProLiant BL660c ISS Technology Update Volume 7, Number 10 - Page 2

ISS Technology Update Volume 7, Number 10 Operating environment for HP SSDs HP server disk drives are available in three levels based on performance: Entry, Midline, and Enterprise. The HP solid state drives introduced in September 2008 represent a level of performance, reliability, and capacity roughly equivalent to Midline server disk drives. More importantly, however, HP server SSDs can deliver this level of reliability in operating environments that are unsuitable for traditional disk drives (Table 1-1). Table 1-1. SSD operating envelope HP server SSD Operating Temperature 0°-70° C Operating Shock 1500 g (.5 ms half sine wave) Vibration 20 g (peak)10 - 2000 Hz Power Consumption (Active) Under 2 watts HP SSD Futures The HP server SSDs introduced in late 2008 represent the first generation of SSDs for ProLiant servers. In the first half of 2009, HP expects to introduce hot-plug SSDs using standard drive carriers. These drives will be supported across the ProLiant product line. As is already the case with hard disk drives, HP is working to develop separate classes of SSDs, each designed to meet the specific capacity, performance and reliability requirements for particular applications. Table 2-1 summarizes the current goals for creating Entry, Midline, and Enterprise SSDs in the future as the technology continues to evolve. Table 1-2.
