Serial Attached SCSI (SAS) provides a superior storage solution. With some storage requirements escalating & others becoming more complex, factors such as flexibility, performance, increased reliability, greater density, security, scalability & accessibility are more critical than ever. Todays organizations consist of different kinds of environments. Enterprise data centers must be online 24 x 7, fulfill requests from numerous users simultaneously, & allow for constant growth & expansion while in operation. Other customer environments require high capacity storage & high data availability for low I/O environments. HPs portfolio of SAS drives meets all these demands.
