1.1 Overview
1.1.1 What is the ExaSAN Solution
Developed by Accusys Storage Ltd., a worldwide leader in RAID (Redundant Array of
Independent Disks) storage systems, ExaSAN (pronounced “X-sa-SAN”) 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 PCIe3.0 protocol that provides 8 Gb/s per lane transfers.
With 4 lane QSFP (Quad SFP) connector and cable, ExaSAN can transfer up to 32 Gb/s by
using single connection.
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 solution, including its complete line of rack mount RAID systems, tower RAID systems,
PCIe switch systems and accessories, for different application purpose, user can build as DAS
(directly attached storage) via PCIe3.0 interface to provide extremely performance, in addition,
Accusys provide SAN (storage attached network) turnkey solution to build a fast and shareable
storage.

4.5.1 Disk Lag Proof
This feature ensures the stability and continuity of the RAID performance. In RAID 5 and RAID
6, DLP prevents the aging or slow responds of a single hard disk from influencing the overall
performance. The advantage of this feature is making sure the data be protected if some hard
disks fail to perform well.
User Guide
Page 36
Note
Slow response of some hard disks can be tolerated in DLP mode, you
may use S.M.A.R.T. function to check the conditions of hard disks in an
array and replace the faulty ones.
5. RAID
In the event of performance degradation or delay of a single drive due to aging, the RAID
system reads both data and parity stripes concurrently. It bypasses the slow reads and returns
data to the host with the regenerated data and to provide stable performance based on the
RAID parity.
4.5.2 NCQ
Native Command Queuing (NCQ) is an extension of the Serial ATA protocol allowing hard disk
drives to internally optimize the order in which received read and write commands are executed.
This can reduce the amount of unnecessary drive head movement, resulting in increased
performance (and slightly decreased wear of the drive) for workloads where multiple
simultaneous read/write requests are outstanding.
The figure above illustrates the access sequence in NCQ and non-NCQ mode. The content
sequences of the two hard disks are the same: 1, 2, 3, 4. However, the access sequence in
NCQ mode may vary to improve the performance.
4.5.3 SMART Mode
S.M.A.R.T. is a monitoring system of disk drives to detect and report on various indicators of
reliability, in the hope of anticipating failure. Accusys RAID system supports S.M.A.R.T. Once
this function is selected, you can select the check interval from the drop-down list. Choose from
1 minute to 8 hours for SMART Mode to be active. The RAID controller will command each hard
disk to perform S.M.A.R.T. according to the check interval selected. The check results will be
shown as an Event message in the main menu.
When running S.M.A.R.T. mode, the performance of the system will be slightly affected. The
higher the check frequency, the more the sequential accesses are affected. It is recommended
to turn off S.M.A.R.T. if high performance required. On the other hand, running S.M.A.R.T.
constantly allows you to monitor the conditions of hard disks at any time.
The options of time to check disk’s S.M.A.R.T are 1,15,30,60 minutes and 2,4,8 hours. We
strongly suggest set to 8 hours. Frequently checking will reduce the life time of hard drives

4.5.4 Beeper
To enable/disable system beeper, default is enabled.
4.5.5 Equalization Mode
Regardless the transmission method, the data transmission speed cannot be guaranteed at all
times. This feature allows the continuous I/Os to operate more smoothly and substantially
reduce large fluctuations in efficiency during data transfer. For video editing, enable equalization
to prevent video frame drops.
4.5.6 Cache
In this section, cache of RAID controller and drive can be configured by manual; default setting
is tuned for video streaming application.
Controller Cache – Check this box to enable the controller cache. This speeds up the data
transfer to and from the disks.
User Guide
Page 38
Caution
Data in cache may be erased if power down unexpected. Suggest
using a UPS (uninterruptible power supply) to prevent this scenario.
Note
If Equalization mode enabled, Synchronize Cache and Read Pre-
fetch will be disabled automatically.
5. RAID
Synchronize Cache – Check this box to enable cache synchronization with drives, to ensure all
write data is correct, there is a frequently latency time within. For video capture, disable
synchronization, because the video capture needs to be able to constantly write data to the
RAID storage without long latency.
Read Pre-fetch – Identifies sequential access patterns and aggressively pre-fetches patters
into cache. From the drop down list, choose the number of stripes to pre-fetch. The default is
32; this is the recommended number.
Drive Cache – Choose which drives to cache. When more than one application accesses the
database, the first applications cache needs to synchronize with the second. Each drive
contains a built in write cache; checking these boxes chooses which drives to enable the
caching on. Caching improves the efficiency and speed of data transfer.
All Drives Cache On/All Drives Cache Off – Click this button to enable/disable the caching on
for all available drives.
4.5.7 MISC
MSIC (Minimal Instruction Set Computer) has standard RAID controller time settings. The time
of each event is displayed in the event logs in Event message.

Usage Scenario:
The access speed of the data stored in the
outer circle is faster than the inner circle.
Suppose there are two slices in a hard
drive, Slice 0 locates in the outer circles
while Slice 1 in the inner circle, for
audio/video editing, you may store video
data in Slice 0 and audio data in Slice 1.
4.6 Option
5. RAID
4.6.1 Slicing
RAID slicing overcomes the inherent design of how data is stored on an drive or RAID system
by subdividing a RAID array into segments, or slices. These slices are effective hardware
partitions of all drives in the array. Each slice is a separate LUN and appears as a separate
volume on the host computer. After slicing, the LUN map must be set for each slice.
Slicing concept
Follow the steps below to select an array to slice or merge.
User Guide
Page 41
Note
Up to 16 slices per array.
The total number of unique arrays’ slices cannot exceed 16.
Note
One slice can only be assigned one LUN.
Up to 64 LUNs
5. RAID
1. Select the array by clicking on a drive with an array number. The capacity is displayed. By
default, Slice 0 contains the entire capacity of the disk array.
2. Click on Slice 0, use the slide bar or button of percentage to slice space and click OK to
confirm. Repeat the same steps to slice more spaces if need.
4.6.2 LUN Map
LUN, which stands for Logical Unit Number, is used to identify a logical unit in computer
storage. When creating an array, you may select Assign LUN automatically to automatically
assign a LUN to the new array. If Assign LUN automatically is not selected, you need to
assign the LUN manually using LUN map.
User Guide
Page 42
Note
The new hard drive must larger than the existing drives of array.
5. RAID
1. Select the array to map by clicking on a drive with an array number.
2. Choose a LUN and from the drop down list select a slice to map to, check the Confirm box
and click OK.
3. Repeat the steps to set more LUN maps if need.
4.6.3 Expansion
Expansion adds spare disk to an existing array. This is no need to create a new array or stop an
array; you may add new disks online while the array is in use, its performance is affected
considerably. You may check the progress of Expansion in the main view.
Example:

5. RAID
Follow the steps below to select an array to expand.
1. Select the array to add additional drives, and select the number of drives to be added. A “+”
sign appears above the drives to be added.
2. Check the Confirm box and click Expand Array.
4.6.4 Migrations
Different from Expansion, which enlarges an array by adding hard drives to a fixed RAID level,
Migration changes the RAID level of an array. It allows live changes to the RAID without the
need to delete the array and rebuild. This can be useful when new drives have been added, and
a new array type needs to be created.
Example 1:
RAID 5 (12 drives) –Migrating RAID 0 ( >11 drives)
RAID 5 (12 drives) –Migrating RAID 6 ( >13 drives)
RAID 5 (12 drives) –Migrating RAID 0+1 ( >22 drives)

5. RAID
4.6.7 Unlock Drives
The RAID controller may lock abnormal drives in an array. You may unlock these drives and
rejoin them in an array. Drives may be locked with one of two conditions:
1. If a drive returns data too slowly, the controller determines the drive is experiencing a failure
and executes Drive Drop. When you unlock the drive, it will be added directly to the array if
there has not been drive access during the locked period. Otherwise, the controller will
rebuild parity data on the drive when the drive is online.
2. When a drive has been used by RAID system, that drive will be locked if insert it to another
RAID system.
Follow the steps below to select a drive to unlock.
1. Select the drive with the icon. It will change to the icon.
2. Check the Confirm box and click Unlock Drive.

5. RAID Overview
5.1 How RAID Works
RAID, or Redundant Array of Independent Disks, is a data-storage technology that spreads data
across multiple drives. This technology provides several benefits
:
Data redundancy for protection and availability
Higher performance as a result of reading or writing on several drives simultaneously
Scalability for expansion of storage
Accusys RAID systems use a hardware controller to manage multiple drives as one or more
RAID array group, which offloads RAID task from host, provides independent, fast and highly
efficient storage.
The way of controller stores and retrieves data on the RAID system is determined by the RAID
level and storage method you choose. Once you have defined a group of drives as an array
group, the controller groups those drives into logical disk, each logical disk appears to the host
system as one Logical Unit (LUN), regardless of the number of actual drives in that logical unit.
RAID System Host System
5.2 RAID Levels
The RAID system supports several RAID levels and configurations. Each level has a different
architecture and provides varying degrees of performance and fault tolerance.
5.2.1 RAID 0: Striping
RAID level 0, striping only, is the fastest and most efficient array type, but offer no faulttolerance. Any drive failure destroys the data in the array.
User Guide 5-1
Page 56
RAID
5.2.2 RAID 1: Mirroring
RAID level 1, mirroring, each drive stores identical data. RAID 1 provides very high data
reliability and improved performance for read-intensive applications, but this level has a high
capacity cost because it retains a full copy of your data on each drive in mirror set.
5.2.3 RAID 5: Striping disks with distributed parity
By distributing the parity information across all drives in a set, RAID level 5 achieves high
reliability and data availability, which allows one of array member disk get failure and keeps
storage work. Disk failure has a moderate impact on the total transfer rate.
5.2.4 RAID 6: Independent data disks with two Independent parity schemes
RAID level 6 extends RAID level 5 by adding an additional parity block; thus it uses block-level
striping with two parity blocks distributed across all member disks. RAID 6 allows two of array
member disk get failure at the same time and keeps storage work.
