xStack Storage User’s Guide 11
Chapter 1 Introduction
The xStack Storage Array is an intelligent, high-performance iSCSI Gigabit Ethernet storage
solution designed for businesses that want to improve the reliability, availability, serviceability,
and performance of their storage systems.
Based on an Internet Protocol-Storage Area etwork (IP-SA ) architecture, the xStack Storage
controller is built around a custom-designed Application Specific Integrated Circuit (ASIC)solution
combining 10Gbps iSCSI, TCP/IP offload, embedded processors and a storage virtualization
firmware stack controlled by firmware loaded into the on-board flash memory. The controller is
housed in a 19-inch 2U rugged hardware enclosure holding up to 8 internal Serial ATA (SATA)
drives, up to 512MB of system memory and up to 4GB of cache buffer memory. Host connectors
for DS -2100 are as follows:
- Four 1GbE RJ-45 host connectors accessed via the rear panel
The xStack Storage Array’s rear panel also has a 10/100 Mbps management port and an RS-232-C
DB9 diagnostic/console port.
Complete configuration and management are available through the intuitive, GUI-based Web
Manager interface. A variety of network configurations are easily established using the xStack
Storage Array’s volume management, initiator, target, network portal, and Link Aggregation
Group (LAG) features. In addition, the xStack Storage Array features Secure Sockets Layer (SSL),
default task priority, cache, TCP/IP, spare count, and battery policy settings for advanced users.

14 Chapter 1 Introduction
1 3 System Overview
Figure 1-1 shows a typical Storage Area etwork (SA ) configuration in which xStack Storage
Array can be used. The Storage Area etwork portion of this diagram is a private high-speed
Ethernet network that is dedicated to the exchange of data between the network servers and the
xStack Storage Array. The high bandwidth used by the servers exchanging data with the xStack
Storage Array can easily consume high bandwidth on the LA (Local Area etwork) where users
PCs are attached. Creating a separate network to isolate this traffic avoids bogging down the
customer’s existing LA and helps improve security.
Figure 1-1 xStack Storage Array System Diagram
xStack Storage User’s Guide 15
Chapter 2 Identifying Hardware Components
This chapter describes the xStack Storage Array’s hardware components.
2 1 Front Panel Components
The following sections describe the hardware components on the front of the xStack Storage
Array enclosure. Figure 2-1 shows the remo able front bezel along with the dri e bays and
major components.
Figure 2-1 Front View of the xStack DSN-2000 Series Enclosure
When installed, the front bezel uses pipes to pass light from the LEDs behind
it to the front for viewing. The bezel itself is passive and has no active LEDs.
16 Chapter 2 Identif ing Hardware Components
2 1 1 LEDs
Figure 2-1 reveals several LEDs that provide useful information about the state of the xStack
Storage Array. The Power LED illuminates when the system is powered. The bicolor Boot and
Fault LED will remain clear during bootup and then green if booting is successful. If the boot
process is unsuccessful, or a system fault occurs, then it will turn red.
Each of the fifteen drive bays has two LEDs associated with it, a bicolor drive activity and
fault LED and a drive power LED. Table 2-1 describes the front panel LEDs and their functions.
Table 2-1 Front Panel LED indicators on the DSN-3000 series enclosure
LED Color Meaning
Power Green ON Power is applied to the system
Green ON Successful boot. No errors encountered. Boot and Fault
ed ON emains clear during boot process. If red after boot process
completed, then an error has been encountered. Please see
management GUI for more information.
Drive Power Blue ON Drive is powered and operational.
Green Blinking Data being transmitted or received from corresponding SATA drive.
Drive Activity and
Fault ed ON Drive has experienced a fault and is offline
2 1 2 Key Lock and Latches
Figure 2-1 shows the xStack Storage Array’s front bezel with key lock and one latch. This
bezel can be locked in place to protect the system from unauthorized drive access and
removal.
Bezel Removal: Simply press inwards (as the arrow reveal) on the left latch shown in Figure
2-1 and pull the left side outwards. The bezel will come off easily providing access to the
drive bays behind it. If the key lock is in the locked position, then the latch cannot be pressed
inwards.
Bezel Installation: Align the bezel in front of the chassis with the bezel slightly to the left.
Carefully insert the catch found on the right side of the bezel under the receptacle found on
the right-front of the chassis and push the left side of the bezel to the right and forward until
the latch locks. The latch is spring-loaded and will lock into place. If you wish, you can use
the key lock to prevent drive access by turning it to the locked position.
xStack Storage User’s Guide 17
2 1 3 Drive Bays
Figure 2-1 illustrates the eight hot-swappable drive bays and their numbering scheme from 0
through 7.
2 1 3 1 Drive and Tray Removal
A drive/tray assembly can be removed by pressing upwards on the green latch found on the
tray and removing it with the handle as shown in Figure 2-2 and Figure 2-3.
Figure 2-2 Drive and Tray Removal
Figure 2-3 Remove Drive/Tray
18 Chapter 2 Identif ing Hardware Components
Removal of a populated drive/tray assembly can have unforeseen effects
including the loss of all data in a volume. A drive can be part of a volume
that may or may not be redundant. Before removing a drive from an
operating xStack Storage Array, make sure it is the correct one.
xStack Storage User’s Guide 19
2 1 3 2 Drive and Tray Installation
A drive/tray assembly can be installed by inserting the drive/tray assembly into the open
drive bay as shown in Figure 2-4. Push the tray at the point indicated in Step 2 of Figure 2-5
and push until it is seated firmly within the bay. As you press, you will see the tray handle
begin to move inwards as the locking mechanism enters the locking slot. When you see this,
then you must push the tray handle inwards as shown in Figure 2-6 until you hear the green
locking mechanism click.
