HP designed the DL980G7 server to take full advantage of Intel’s most powerful Xeon® processor 7500 series with Quick Path Interconnect (QPI). The HP DL980 G7 delivers an enhanced level of scale-up x86 performance, availability, and reliability. The HP DL980 G7 is the first server to use the HP PREMA Architecture, incorporating a node controller design with smart CPU caching and redundant system fabric.
With PREMA Architecture HP addresses customer requirements that have exceeded the performance and capacities offered by 4-socket x86 systems. The architecture supports a balanced system with more processors, more memory, and more I/O than previous generation x86 systems have provided.
The HP PREMA Architecture groups the processor sockets into multiple “QPI islands” of two directly connected sockets. This direct connection provides the lowest latencies. Each QPI island connects to two node controllers. The system contains a total of four node controllers. Each node controller stores information about all data located in the processor caches. This functionality is called “smart CPU caching.” Smart CPU caching provides significant benefits for system performance.
By reducing processor overhead, The ProLiant DL980 G7 server delivers better system performance for a diverse set of workloads than competitive 8-socket and even larger systems. VMs, SAP, Microsoft SQL Server, and High Performance Computing applications will experience performance gains on this server.
The performance gains enabled by HP PREMA Architecture make it possible for a single ProLiant DL980 G7 server to support workloads previously running on many legacy servers. As a result you lower the space, power and cooling requirements needed to run those workloads.
