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).

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.
