The HP Apollo 2000 System offers a very dense solution with up to four independent HP ProLiant XL170r Gen9 hot-pluggable server nodes in a standard 2U chassis. Each XL170r Gen9 Server node can be serviced individually without impacting the operation of other nodes sharing the same chassis to provide increased server uptime. Each server node harnesses the performance of 2133 MHz memory (16 DIMM slots per node) and dual Intel® Xeon® E5-2600 v3 processors in a very efficient solution that shares both power and cooling infrastructure. The HP Apollo 2000 System also delivers increased storage flexibility with options that support SAS/SATA/SSDs and also enabling flexible allocation of drives per server node.
