Introduction
Overview
Designed around ioMemory, a revolutionary storage architecture, HP IO Accelerator is an advanced NAND
flash storage device. With performance comparable to DRAM and storage capacity on par with hard disks,
flash storage device. With performance comparable to DRAM and storage capacity on par with hard disks,
the IO Accelerator increases performance so that every server can contain internal storage that exceeds the
I/O performance of an enterprise SAN.

HP IO Accelerator is the first data accelerator designed specifically to improve the bandwidth for I/O-bound
applications.
In addition to the hardware driver, the IO Accelerator also includes a VSL. This hybrid of the RAM
virtualization subsystem and the disk I/O subsystem combines the best features of both systems. VSL functions
as a disk to interface well with block-based applications and software, while also running like RAM
underneath to maximize performance. This feature produces the following benefits:
•
Performance: The VSL offers direct and parallel access to multiple CPU cores, enabling near linear
performance scaling, consistent performance across different read/write workloads, and low latency
with minimal interruptions and context switching.

•
Extensibility: The VSL enables flash-optimized software development, making each IO Accelerator
module a flexible building block for creating a flash-optimized data center.
