About This Guide
Congratulations on your purchase of the ExaSAN (pronounced X-sa-SAN) B08S2-PS, a revolutionary
high bandwidth storage system, specifically designed for all post production storage. It delivers stability,
exceptional performance, and scalable capacity at a very affordable ownership cost.
This gui de also contains instructions for installing and using the ExaSAN B08S2-PS system and RAID
(Redundant Array of Independent Disks) technologies and RAIDGuard X (ExaSAN’s RAID management
software).
If you are new to RAID and RAIDGuard X, this guide will help you become familiar with these
technologies, and assist you in setting up and using RAID on the B08S2-PS. If you are already familiar
with these technologies, use this guide as a reference for implementing your ExaSAN B08S2-PS RAID
solution to achieve maximum performance and reliability.

1. Introduction
1. Introducing ExaSAN PCIe2.0 Storage Systems
1.1 System Overview
Your new ExaSAN (pronounced “X-sa-SAN”) PCIe 2.0 Storage System “B08S2-PS” is one of a family
of PCI-express based storage and switch solutions from Accusys capable of transferring data at up to 20
Gb/sec. The small form factor B08S2-PS can be used on a desktop, rack, or in a transportable
environment as a DAS (Direct-Attached Storage) or SAN (Storage Area Network) storage solution for the
post production and broadcasting industries that require high 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 family of storage and switch products that take advantage of well known
PCIe (PCI Express) technology speeds, standards, and roadmap. The current ExaSAN products employ
PCIe2.0 protocol that provides a 5 Gb/sec per lane transfers. With 4 lane QSFP (Quad SFP) connectors
and cables, ExaSAN can transfer up to 20 Gb/sec using single port QSFP HBA’s. With a dual port
QSFP HBA, data transfers up to 40 Gb/sec are available to the connected workstation. The ExaSAN total
solution, including its complete line of rack mount systems, tower systems, PCIe switch systems and
accessories, puts the benefits of shared, scalable, and high-performance storage within easy reach of
organizations w ith limited IT resources and budgets.
Post production work including non-linear editing (NLE) requires high bandwidth storage to quickly
move the volume of data being processed, and ExaSAN storage solution meets those demands. The high
bandwidth provided by ExaSAN technology allows the client to complete editing tasks in a much shorter
time to save time and money. ExaSAN is available as a complete solution that includes the PCIe RAID
system, cable and HBA card in a DAS configuration.
Figure 1 below depicts the ExaSAN B08S2-PS system solution architecture in a DAS environment.
Figure 1: B08S2-PS DAS environment
Whether it’s collabor ative video editing in a post-production workgroup, or a shared research project in a
university, the ExaSAN solut ion offers a range of performance levels and storage capacities t hat scale to
meet the needs of small-to-medium-sized organizations. Equally important and useful 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.
User Guide Page 1-1
1. Introduction
Figure 2 below depicts a typical ExaSAN system solution architecture in a SAN environment.
Figure 2: B08S2-PS SAN environment
1.1.2 What is the ExaSAN B08S2-PS Solution
The ExaSAN B08S2-PS is a 8Bay disk array system in a small form factor employing the latest PCIe2.0
technology with support for RAID level 0, 1, 5, 6, 0+1, high speed 2.5” 6Gb SAS and SATA II drives.
The Single port RAID controller of B08S2-PS combined with 8 drives can provide up to 20 Gb/s
transfers.
Your ExaSAN B08S2-PS system package consists of the components listed below.
1. ExaSAN B08S2-PS PCIe RAID system, see Section 1.1.3.1 and 1.1.3.2
2. QSFP-PCIe 2.0 Host Bus Adapter, compatible with PCIe 2.0 and 1.1 slots on the host server, see
Section 1.1.3.3
3. QSFP 2M copper cable for connecting the HBA installed in the host to the RAID. Additional cables
are optional, see Section 1.1.3.4
4. AC power adapter and Power cord, see Section 1.1.3.5
Note that items 1 through 4 are Accusys-supplied equipment as part of the B08S2-PS package. The host
server and HDD for the RAID are not Accusys-suppl ied equipment Contact your System Integrator/Value
Added Reseller if you need assistance in purchasing these components.
1.1.3 ExaSAN B08S2-PS Components and Accessories
This section provides detailed description of each system component and accessories included in the
B08S2-PS package.
1.1.3.1 ExaSAN PCIe RAID System
The B08S2-PS RAID system is a small trans portab le RAI D system supporting up to 8 hot swappable hard
drives or flash drives (sold separately). See 1.1.3.2 for HDD / SSD.
The RAID system includes a chassis, RAID controller, and disk trays only.
User Guide Page 1-2
1. Introduction
1.1.3.2 Hard Disk Drive (HDD) or Solid State Disk (SSD) for th e RAID System
Hard disk drives or solid state disks come in different storage capacities and performance levels. All 2.5”
hard drives or SSDs for the B08S2-PSshould be the sam e size, speed, model, and firmware.
Accusys recommends 2.5” SAS and SATA Enterprise HDDs for the B08S2-PS systems.
1.1.3.3 ExaSAN QSFP Host Bus Adapter (ACS-63200NT)
The ExaSAN QSFP HBA (Figure 3) requires an available PCIe x4, x8, or x16 slot in your client system.
Note that the PCIe slots on some motherboards are for graphics cards only. (Check your motherboard
documentation or verify with the motherboard vendor for compatibility. Also note that some PCIe x4 or
x8 slots only share or run at PCIe1.1 speed, so please be advised to consult your motherboard
documentation to take advantage of ExaSAN speeds
Figure 3: ACS-63200NT(Z1M) HBA card
1.1.3.4 QSFP (Quad Small Form-factor Pluggable) PCIe Copper or Optical Cables
A 2m QSFP Copper Cable is included in your B08S2-PS system package. It is used to connect the host
system to the storage system.
Optional QSFP cables (Figure 4) are available at varying lengths in copper or optical
1. 2m QSFP Copper Cable, (black in color)
2. 10m QSFP Optical Cable, (orange in color)
3. 30m QSFP Optical Cable, (orange in color)
4. 50m QSFP Optical Cable, (orange in color)

1.5 What Else You Need
When you purchased your ExaSAN system, additional hardware, software, and accessories may be
required to fully take advantage of this system. The following describes the software and hardware which
you may need to purchase separately. If you still have questions, please consult with your ExaSAN
reseller for more details.
1.5.1 DAS environment
DAS is the acronym for Direct Attached Storage (to the client workstation or server) The B08S2-PS is
directly attached to the HBA installed into the client workstation or server shown in Figure 11.
Figure 11: B08S2-PS DAS env ironment
1.5.1.1 Hardware
1. 2.5”SAS/SATA HDD (hard drive) or 2.5”SSD(flash dive)：B08S2-PS supports both SAS and
SATA interface HDD/SSD drives. Recommend using Enterprise level of the same model, size, and
firmware. The B08S2-PS HDD compatibility list is here:
(
http://www.accusys.com.tw/B08S2/B08S2/download.html)
2. Host system computer: When connecting B08S2-PS, you will need a host workstation or server with
an available PCIe2.0 x4 (or larger) slot to install the ExaSAN HBA. Please confirm manufacturers
specifications for PCIe2.0 support to get 20Gb/s transfers from the B08S2-PS.
Accusys cannot guarantee ExaSAN product compatibility with all workstations and
motherboards on the market, so please check with your supplier to get maximum
performance from ExaSAN storage
