A Deeper Look at POWER8 CAPI and Data Engine for NoSQL
IBM Systems Magazine, May 2015
NoSQL and CAPI create a new tier of memory by attaching up to 40 TB of auxiliary flash memory
to the processor without the latency issues of traditional I/O storage.
This article explains CAPI (Coherent Accelerator Processor Interface) technology and describes how it’s
being used in the Data Engine for NoSQL,
the first exploiter of the CAPI platform.
IT organizations must provide increased system performance as their workloads grow with demands for big data analysis,
social media applications, technical computing, continuous customer connectivity and business-specific applications.
Increases in processor performance can no longer satisfy the workload demands, so solutions must also come
from system-level advances such as hybrid computing, processing engine customization and open platform development
that enables cross-company innovation.
Many solutions will keep improving price-performance through specific function accelerators.
These accelerators are delivered by GPU- and field-programmable gate array (FPGA)-based solutions.
We already see these solutions today with I/O-attached acceleration engines, such as an NVIDIA GPU
placed on a PCIe card.
