1. Introducing ExaSAN PCIe 2.0 Storage System

1.1 System Overview

Your new ExaSAN (pronounced “X-sa-SAN”) PCIe 2.0 Storage System is a rack mounted

storage that can be used as a DAS (Direct-Attached Storage) or SAN (Storage Area

Network) for the post production and broadcasting industries that require high

bandwidth. Furthermore, the A12S2-PS supports the latest PCIe 2.0 standard providing a

20Gb bandwidth.

1.1.1 What is the ExaSAN Solution

Developed by Accusys, Inc., a worldwide leader in RAID (Redundant Array of

Independent Disks) storage systems, ExaSAN is a system solution built for simple, cost-

effective deployment and storage management. Employing PCIe (PCI Express)

technology, the PCIe 2.0 Storage System uses QSFP cabling technology to natively

transmit at low latency PCI Express Gen 2 protocol. Each channel under PCIe 2.0 can

transmit at 500MB/s, giving PCIe 2.0 x4 storage systems a 20Gb bandwidth and PCIe

2.0x8 a 40 Gb bandwidth. The ExaSAN total solution, including its complete line up of

rack mount system, tower systems, PCIe switch systems and accessories, puts the

benefits of shared, scalable, and high-performance storage within easy reach of

organizations with limited IT resources and budgets.

Post production work such as non-linear editing (NLE) requires especially high

bandwidth storage to support the volume of data being processed, and ExaSAN

storage solution is designed to meet such demands. The high bandwidth enabled by

ExaSAN technology allows the client to achieve the maximum efficiency with minimum

cost, while its enhanced functionality provides continuous and smooth data transfer to

prevent frame drop or lagging of projected content. ExaSAN is a complete solution that

includes the PCIe RAID system, cable and HBA card.

Figure 1 below depicts the ExaSAN A12S2-PS system solution architecture. Note that it

can be expanded from one RAID system to three systems (daisy-chaining from 1x RAID

controller).

1. Introduction

User Guide Page 1-2

Figure 1

Whether it’s collaborative video editing in a post-production workgroup, or a shared

research project in a university, the ExaSAN solution offers a range of performance

levels and storage capacities that scale to meet the needs of small-to-medium-sized

organizations. Equally important is its integrated design, centralized administration and

monitoring, and a suite of built-in management tools; which eliminate the need for a

staff of experts to install and maintain a SAN for the workgroups.

Figure 2 below depicts a standard ExaSAN system solution architecture.

1.1.2 What is the ExaSAN A12S2-PS Solution

The ExaSAN A12S2-PS is a 2U12Bay disk array system designed for all high-end post

production storage usage, with the latest interface technology PCIe 2.0 and innovative

green design, supports RAID level 0, 1, 5, 6, 0+1, high speed 6Gb SAS drives, and high

capacity SATA II drives. The Single port RAID controller of A12S2-PS combined with 12

drives can provide 20Gb bandwidth with its unique Performance Optimization feature.

Your ExaSAN A12S2-PS system consists of the standard components listed below in this

section. Note that items 1 through 5 are Accusys-supplied equipment as part of the
