NEC’s Service Acceleration Platform for Power Systems Accelerates and Scales Cloud Data Centers

By Shinji Abe, Senior Manager for IT Platform Division of NEC

As usage of the cloud expands, cloud data centers will need to be able to accommodate a wide range of services, from office applications to on-premises services and in the future: the Internet of Things (IoT). To meet these needs, the modern data center requires the ability to simultaneously handle multiple demands for data storage, networks, numerical analysis, and image processing from various users.

NEC’s new Service Acceleration Platform addresses this need by working at the device level to assign resources to perform computation and scale up individual performance and functionality. Unifying standard hardware and software components, the Service Acceleration Platform delivers faster, more powerful, and more reliable computing solutions that meet customer performance demands.

What is ExpEther?

The architecture of the Service Acceleration Platform is based on NEC-developed ExpEther technology (http://www.expether.org/index.html).The ExpEther Technology can extend PCI Express beyond the confines of a computer chassis via Ethernet without any modification of existing hardware and software. Computer resources can be added on standard Ethernet fabric the same as adding into the chassis to provide scale-up flexibility. ExpEther can build a new type of computing environment without physical constraints, and is cost effective with the use of standard Ethernet.

In IoT data processing, various data with various characteristics are generated from the physical inputs. To accelerate the processing of these inputs, various accelerator engines are necessary depending on the workload.

CAPI Capable ExpEther Engine

NEC extended the ExpEther functionality for CAPI compliance and confirmed that ExpEther technology can extend CAPI-attached devices remotely from the CPU via an Ethernet switch.
