Chapter 1 – Introduction
1.1 Overview
The RamSan-500 is the World’s Fastest Flash-based storage system. The
basic unit contains nine RAID-protected Flash storage modules accessible
from the front, with a combined usable capacity of either 1 or 2-Terabytes
and a data bandwidth of 2 GB/sec. A single RamSan-500 fits in 4U of rack
space. Multiple RamSan-500 units scale capacity, bandwidth, and IOPS.

Unlike other mass storage products, the RamSan-500 is not based on
mechanical rotating disk technology, but instead on high performance
memory technology. While each of the nine Flash storage modules may
look like a disk, there are no moving parts and it operates with a much
faster protocol, reducing access time and increasing the data transfer rate.
This is achieved with the use of better connectors (rugged, more data
pins) and a simple transfer protocol.
While the capacity and throughput of the RamSan-500 is impressive, the
key to the system’s power resides in its I/O structure. The RamSan-500
can be configured with 2-8 Fibre Channel (FC) ports. Internally, it can
handle the bandwidth and supply the IOPS needed for emerging storage
applications.

The RamSan-500 is easy to install on a Fibre Channel SAN or directly
attached to a server. Most common parameters, including the
management Ethernet port, can be set from the front panel. The
RamSan-500 also has monitoring and configuration capabilities
through a Web browser.
