Rack Warnings
If you plan to rack mount the PixelStor 5000, follow the rack manufacturer’s safety instructions.
Install the enclosure only in a rack that has been properly secured in an area with suitable
environmental conditions.
Have someone assist you during physical installation.
To properly ventilate the system, you must provide at least 7.6 cm of clearance at the front
and back of the system.
To reduce the risk of personal injury or damage to equipment, always ensure that the rack is
adequately stabilized prior to extending a component outside the rack. A rack may become
unstable if more than one component is extended. Extend only one at a time.
Do not stand or step on any components in the rack.
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient. Therefore, consideration should be
given to installing the equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
Do not overload the AC power supply branch circuit that provides power to the rack.
Observe extension cable and power strip ratings. Ensure that the total ampere rating of all
equipment plugged into the extension cable or power strip does not exceed 80 percent of
the ampere ratings limit for the extension cable or power strip.
System Warnings
Avoid dust, humidity, and extreme temperatures; place the system on a stable surface.
To reduce the risk of personal injury from hot surfaces, allow the hot-plug disk modules and
other system modules to cool before touching them.
To reduce the risk of electric shock or damage to the equipment, do not disable the power
cord grounding plug. The grounding plug is an important safety feature.
Ensure the power cord is inserted into a grounded electrical outlet that is easily accessible

About This Manual
The capacity of the PixelStor 5000 can be expanded by connecting multiple 2U/12 bay PixelStor
100e/312e or multiple PixelStor 324e 4U/24 bay expansion enclosures. The PixelStor
100e/312e is provided in single or dual controller configurations while the PS324e is a single
controller on product. The PixelStor 100e/312e enclosures can also be populated with 12 hot
plug SATAIII or SAS hard disk drives while the PS324e can be populated with 12 hot plug
SATAIII or SAS hard disk drives. These can be daisy chained to a PixelStor 5000 via fast 24
Gbps SAS connectors for low cost high performance scalability.
1.4 System Features
Figure 1-1 PixelStor 5000
Unparalleled Flexibility
– The PixelStor 5000 offers iSCSI SAN host connectivity within the
same box. This functionality makes the PixelStor 5000 one of the most flexible storage building
blocks on the market today. The flexibility inherent in the PixelStor 5000 allows customers to
address diverse needs in the storage space without the need for multiple specialized platforms.
Zero Down-Time Architecture
- In the PixelStor 5000, every active component, including
drives, controllers, fan trays, and power supplies, are hot swappable without interruption in
service or loss of data. Its active-active dual controllers, sophisticated mirrored and battery
backed cache and path failover capabilities give the PixelStor 5000 best-in-class system fault

tolerance.
Active-Active Controllers & Transparent Fail-over & Fail-back
- Fast throughput and data
availability are paramount for dedicated storage systems. This is why PixelStor 5000 is
designed with active-active controllers to improve both performance and data availability.
Each Disk Group has an assigned “primary” controller to take advantage of the fastest route to
the drives. So, optimal performance is achieved when traffic goes through both controllers to
their associated Disk Groups. For availability, both controllers can serve any Disk Groups
within the system. When there is a controller failure Disk Groups assigned to the failed
controller will automatically “migrate” to the surviving controller without user intervention. When
the failed controller is replaced, the systems will automatically fail-back to its original state. In
PixelStor 5000, the relationship between two controllers is tight. Each controller has the
precise status of the other, which results in quick and accurate actions when failure happens.
Mirrored Cache
- With Dual controllers, the “auto cache” option puts a mirrored copy of the
write cache on the redundant controller. The data is fully protected. If there is a failure in any
controller, the system flushes the mirrored copy and automatically switches to the
“write-through” setting. This is the best compromise between performance and protection.
Multi-Path IO and Cache Coherency
- The PixelStor 5000 makes no assumption regarding
the behavior of the hosts since they can switch from one path to the other. This is normally
referred as “multi-path IO” – a technology to ensure the end-to-end high availability for path
failure. RASILIENT Systems patent-pending technology supports path failure with our cache
coherency features. In the extreme case, the host can send commands to either controller
randomly.
Dedicated SATA Channels
- PixelStor 5000’s multi-path design provides a dedicated drive
channel from each controller. The elimination of inter-drive dependencies enhances
performance. The independent controller access provides additional data availability.
Disk Roaming
- In the PixelStor 5000, the concept of Disk Groups is introduced, which
represents a set of drives that share similar characteristics. The Disk Group configuration,
including RAID, and volume, roams with the drives. Once inserted, the Disk Group can be
discovered and the service can start with a mouse click. Within the enclosure, the drives can
also be moved around. The roaming operation can be carried out while the system is on-line.
Users can take advantage of this flexibility to arrange their storage for different on-line and
off-line tasks. This feature provides a basic and inexpensive way to upgrade a system and
retain your data or move drives to another system for basic system recovery.
Capacity Expansion
– The PixelStor 5000 has the best capacity expansion capability on the
PixelStor 5000 User Manual
Rev. 1, May 2013

About This Manual
market. The 2U/12 bay controller unit can be expanded with up to eight 2U/12 bay PixelStor
100e/312e/324e expansion enclosures for a total capacity of 108 SATAII drives. The PixelStor
100e/312e provide 2U and 12 bays single or dual controller expansion enclosures and PixelStor
324e 4U/24 bay single controller expansion enclosure. These enclosures can be hot added to
the system via the PixelStor 5000 24Gbps SAS connectors. The capacity expansion feature
simplifies the task of adding additional storage capacity. You can expand Disk Groups across
enclosures. The user can expand the LUN capacity on-line within the Disk Group, or expand the
Disk Group by adding disks from the pool of global spare disks.
Software RAID
- The PixelStor 5000 architecture focuses on the critical performance elements
of protocol processing and data movement. The powerful multi-core processor and server
chipset (high-speed front-side bus and DDR3) present a data mover architecture that is
superior over embedded processor solutions found in traditional storage arrays. Traditional
embedded solutions tend to be a generation behind in memory technology and require special
chips to enhance performance. With a dedicated IA processor with multiple cores in our array,
there is little benefit of using expensive “hardware” RAID. “Hardware” RAID is important in
general-purpose servers to off-load the CPU. In an external array with dedicated controllers
and memory, “hardware” RAID only adds cost.
Global Spares
- In PixelStor 5000, any drives not assigned to a Disk Group are automatically
available as global hot spares. If a drive fails, the RAID controller can automatically rebuild its
data on the spare drive without requiring intervention by the administrator. The rebuild
operation occurs in the background while the controller processes normal operations.
LUN Masking
- Authentication and Access Control List (ACL) - Enterprise data must be
secured and closely guarded. In PixelStor 5000, LUNs are only exposed to the hosts that
have authority to access them. This is generally referred to as LUN masking. In addition,
CHAP authentication is used for each iSCSI session login. All management access is also
protected with the access control list, which filters out the machines that are not on the list.
Active Mid-plane
- PixelStor 5000 is built around an active mid-plane. This permits the
PixelStor 5000 to achieve a shorter chassis length and a smaller foot-print. Additionally, a single
component failure only affects one drive of a Disk Group.
Robust Enclosure
- Both the enclosure and the drive carriers are designed for operation
without IO errors in various temperature and vibration conditions. The whole enclosure is built
in one piece. Extensive thermal and vibration testing has been conducted on the enclosure by
itself and in a densely populated rack. Special attention has been taken to recover the data path
failure due to signals stuck at zero or one. In addition, each active component such as the
drives and controllers monitor the incoming current and shut down power in case of a

short-circuit.
Simple, Intuitive Configuration
- The web based management utility called the PixelStor
Storage Manager has been designed to be intuitive and extremely easy to use. It requires little
to no training. With the PixelStor Storage Manager, a system administrator can set up a system
in 6 simple steps. The utility allows you to:
Assign System IP address(s)
Select and name multiple drive groups and establish different RAID levels for each group.
Create and size virtual drives for each drive group. The system supports up to 256 LUNs.
Create a list of available hosts with WWN's and IP addresses
Present Volumes to Hosts
Establish access rights to each virtual drive with the option to enable powerful security
policies to each virtual disk. Add capacity, check system status, set email alerts in the event
of system problems.
System Management and Full Monitoring Capability
- RASILIENT Systems is committed to
developing storage arrays that reduce administrative complexity and management costs.
PixelStor 5000 comes with powerful remote management software that dramatically simplifies
setup and monitoring of storage volumes. The robust self-monitoring technology and automatic
notification service maximizes storage availability while minimizing the pressure on system
administrators. In the event of a hardware failure, PixelStor 5000 can automatically notify you
via email. The user interface also provides monitoring for each hardware module. The log
and all system information are kept in persistent memory, which can be recovered after reboot.
For remote diagnostics, the administrator can dump the whole log to a remote email address
with a single mouse click.
Non-disruptive On-Line Firmware Update
- Using PixelStor 5000, there is no need to take
your system down when upgrading the firmware. As part of the high-availability design,
PixelStor 5000 keeps mirrored copies of its System Software in flash on each controller. You
can upgrade the kernel on-line with no disruption of service.

To improve the utilization of the available storage capacity and ensure
reliability, it is recommended that all disk drive modules within a DG be the
same size and from the same manufacturer. This is because for each RAID
Group, the system scales down to the size of the smallest drive (except for
RAID 0).
Introduction
2.1.2 Rules for Adding Storage
PixelStor 5000 and PixelStor 100e/312e/324e expansion enclosures follow the concept of “disk
groups”. A “disk group” (DG) is composed of an associated group of disks with similar RAID
properties. All DGs must be assigned a RAID level. The system supports RAID 0, 1, 5, 6, 50, 60
10. The following rules must be followed when creating DGs for a PixelStor
5000/100e/312e/324e system:
A DG can span across interconnected PixelStor 5000 and PixelStor 100e/312e/324e
systems.
Drives within a DG can reside in any order across any of the enclosures in a system.
Capacity of a DG can be expanded by adding disks from the available pool of global spare
disks. (Adding disks to a disk group may require multiple disks.)
DGs can be accessed by either controller, but must be assigned a primary controller.
Drives not assigned to a disk group will be classified as “Global Spares”
Global spare(s) can reside on any of the interconnected chassis to protect any DG. A Global
Spare cannot be added to RAID 0 DG.
Failed disks or disks disassociated from their disk group will be classified as “Orphans” by
the system.

3.3 Installing Hardware Modules
3.3.1 Controller Modules
This PixelStor 5000 is designed to operate with one or two controller modules. When the
PixelStor 5000 is equipped with dual controller modules, the hot-swappable redundant function
is enabled. If one controller module fails, the surviving controller takes over all storage volumes
and host connections. With redundant controllers, you can replace the failed controller module
without powering off the PixelStor 5000, because the surviving controller module takes the
place of the failed one.
The location of the controller modules on the chassis is shown below:

network separate from you data network for security and performance reasons.
Hardware Installation
4 System Configuration
Once the physical hardware components are installed, you are ready to start configuring your
storage. First you will need to set up the PixelStor 5000 on your network.
4.1 Initialize the System
The PixelStor 5000 ships with 5 to 10 Gigabit Ethernet (GE) ports per system depending on
your purchased configuration. These are bonded together using RASILIENT’s IP redirect
technology. RASILIENT offers additional flexibility by offering the ability to set one of these GE
link links as a separate out-of-band management port.
By default the system ships with all the included GE links bonded together into one IP address.
This provides the best performance because the system intelligently balances IO requests
across the multiple bonded GE links. This approach also offers the best fault tolerance because
if any link goes down, hosts can continue to access the PixelStor 5000 via the surviving GE
links.
With the physical hardware components installed, you are now ready to initialize the system
and start configuring your storage. The first step in setting up the PixelStor 5000 is to get it
ready to connect to your network. There are two options for setting up the PixelStor 5000 on
your network.
4.1.1 Option 1 – Use Pre-configured IP Address to Connect to System
Each PixelStor 5000 comes pre-configured with an IP address. Once you have connected your
PixelStor 5000 to your network and started the system, you can use the web based PixelStor
Storage Manager included with your system to configure your storage. Using the PixelStor
Storage Manager and default IP addresses instead of the CLI is recommended, especially if this
is your first time setting up a PixelStor 5000 . The PixelStor Storage Manager is designed to get
your system up and running in six simple steps.
PixelStor 5000 User Manual
Rev. 1, May 2013
4-17
There will be only one base System IP address regardless of number of physical
GE ports or number of controllers.
When PixelStor 5000 is started for the first time, the system may take 1-2 minutes
as it does a full system check. This only happens on the first start-up or after an
improper power shut down. If the system is restarted during the initialization
sequence, the process starts over from the beginning. Please wait for the system to
finish its initialization sequence to avoid start-up delays.
The workstation that will be used for system configuration should be on the same
subnet as PixelStor 5000 . Set the Workstation IP address to 192.168.0.x and the
net mask to 255.255.255.0 before trying to access the PixelStor Storage
Manager.
Hardware Installation
1. Power-on PixelStor 5000, using the DC power/standby switch-on each power supply.
The green DC power light on the power supply will turn on and stay on. The green
activity light on each installed disk drive should be on. The PixelStor 5000 comes with its
own pre-installed system software. When the system is powered on, the system
software boots automatically.
2. Move to a workstation with a web browser such as Microsoft Internet Explorer on the
same subnet as PixelStor 5000 . Type http://192.168.0.1 into the web browser address
window to access the PixelStor Storage Manager.

side of the browser window (Steps 1-6) to guide you through the setup process.
4.1.2 Option 2 – Configure Private IP Address to Connect to System
Before connecting the PixelStor 5000 to your network, you will first need to access the built-in
Command Line Interface (CLI) that is included with your system. The PixelStor 5000 is
designed with one mini-serial port on the back of each controller module. This can be used to
PixelStor 5000 User Manual

See Appendix B – Using the Command Line Interface, for more information on the
CLI and a full list of commands. The mini-serial port is configured for 115.2K Baud,
N81.
When the PixelStor 5000 is started for the first time, the system may take 1-2
minutes as it does a full system check. This only happens on the first start-up or
after an improper power shut down. If the system is restarted during the initialization
sequence, the process starts over from the beginning. Please wait for the system to
finish its initialization sequence to avoid start-up delays. The mini-serial connector
can be connected to monitor information sent to the console during the boot
process.
Hardware Installation
connect a serial console to the PixelStor 5000 to manage the system. The CLI can be accessed
via a terminal emulator running on a PC or laptop connected directly to the mini Serial port on
the back of the PixelStor 5000 .

Figure 4-21 Disk Group Discovery
Orphan Disks
An Orphan Disk is a disk that contains information about membership in a Disk Group that has
either been removed from the Disk Group or is designated as an Orphan because there are not
enough of the Disk Group members available in the system to build the Disk Group.
This condition can occur when a disk has been improperly removed from the system and a hot
spare disk has replaced the Orphan Disk in the Disk Group. Since the Disk Group is rebuilt
using the Spare Disk, the Orphan cannot be used in the Disk Group.
This condition may also occur when some of the disks from a Disk Group are moved to a new
chassis. Without enough Disk Group members present to reassemble the Disk Group, the
system labels the disks as orphans. In this case, you can either locate and add the missing Disk
Group members or convert the Orphan Disks to Spare Disks and rebuild the Disk Group from
available Spare Disks. In this case all information on the disks will be lost.
Converting an Orphan Disk to a Spare will remove all data from the disks. Only those disks that
are in an Orphan state may be selected to be converted. Click on the Convert button in the
Orphan Disk to Spare disk page, shown in, to convert the disks.
