Understanding D3-10i Array Management
The D3-10i array is flexible enough to be implemented in a number of ways, from a single-server storage
solution up to a multi-server SAN infrastructure. No matter which approach is used, the array requires an
Ethernet connection to a server and client that will perform management functions and an Ethernet connection
to servers that will access the array’s storage.
Figure 2. Sample D3-10i Infrastructure Design
Even though these roles can be implemented on a single server, this document describes these as distinct
server roles as follows:
Management Server –The management server role is performed by a server with the Storage
Manager software installed. This server is attached to the array via an Ethernet connection.
Management Client –The management client role is performed by any Windows workstation or server
that connects to the management server via the Web-based management interface.
Application Server –The application server role is performed by any server that uses the array
storage via an iSCSI connection.
Requirements
The following equipment, tools, and resources are required to complete this installation.
Network Cables –At least two Ethernet cables will be required.
o1 Ethernet cable is required for connection to the management port.
o1 Ethernet cable is required for each iSCSI port that will be used for connections to application
servers.
IP Addresses –There is one management port and two iSCSI ports on each controller. Each port that
will be used requires a unique IP address. Those IP addresses should be reserved and all associated
network settings should be confirmed before installation.
Tools –You will need the installation CD (shipped with unit) and a #1 Phillips-head screwdriver.
Rack space –If rack-mounting, 2U of rack space is required for each base unit and an additional 2U of
space is required for each additional disk enclosure.
Power Requirements –Two available outlets providing AC 100-240V single phase 50/60Hz for a
NEMA 5-15P plug will be required for each base unit and each disk enclosure. Power and cooling
requirements are listed in the table below.

STEP 1: Planning and Preparation
This section describes the planning and preparation steps that need to occur before you install the array.
Preparing For Installation
Before installing the array, the following steps should be performed on the application servers that will be
connected to the array:
1. Install any additional gigabit Ethernet NICs on all application servers as needed for iSCSI connectivity.
2. Install and apply the latest driver updates for all application server NICs that will be used for iSCSI
connectivity.
3. Ensure that the array and application servers will reside on the same network subnet and all necessary
IP addresses have been reserved for each iSCSI port that will be connected to that network.
4. Optional: Install and configure at least one iSCSI Naming Services (iSNS) Server on the same network
segment as the array and the application servers that will connect to the array.
5. If a specialized iSCSI HBA will be used instead of a software iSCSI initiator, ensure that all iSCSI
adapters and iSCSI switches, if used, are installed and configured on all application servers as
specified by the hardware vendor.
Note: Check with your D3-10i sales representative to get the latest information about iSCSI HBAs that
have been certified for use with the D3-10i array.
Unpacking the Array
While unpacking instructions are illustrated on the array packaging materials, the following tips should be kept
in mind when unpacking the base unit.
To prevent component damage caused by condensation due to rapid temperature and humidity
changes, please allow the base unit to sufficiently acclimate to the ambient room temperature before
unpacking.
To prevent injury, the array should be unpacked, lifted out of the packing materials, and moved by at
least two people.
To prevent damage to the base unit, the unit should be held by the bottom of the unit when removed
from the packing material or moved. It is not recommended to lift or carry the unit by holding on to
projecting surfaces such as the power supply units or plastic bezel mounts.
Please save all packing materials in case the unit needs to be returned for repairs or shipped to other
locations.
Record the array serial number and model number located on the back of the array or inside the
cabinet door of the array, then visit http://www.necam.com/registration to fill in your self-support
registration information in order to receive an additional 30 days of warranty coverage.

STEP 2: Array Installation
This section describes the steps necessary to complete the physical installation of the array. These steps
should occur before you connect the array to a server.
Hardware Installation
This section describes the steps you need to perform to physically install an array into a rack and prepare for
connection to any servers.
Mounting the Array
Before mounting the array in a rack enclosure, please observe the following:
When installing both disk enclosures and base units in the same rack, the disk enclosures should be
mounted above the base unit.
If an optional external battery backup unit (BBU) will be installed in the same rack, at least 1U of space
should be reserved underneath the base unit for the external BBU.
If the array is being installed into a rack containing other equipment, the heaviest rack units should be
mounted as close to the bottom as possible, while lighter units can be placed near the top.
For the purpose of determining the proper positioning in the rack, a fully loaded base unit may weigh in
excess of 68 lbs and a fully configured disk enclosure may weigh in excess of 63 lbs.
Figure 5. Mounting the Array
The rack mount rail mounting points are illustrated in Figure 5 above and show M5 screw placements for the
two center screw holes in the front of each rail. Screws are positioned above and below the inner rail tabs at the
rear of each rail as well. The array then slides into the rails from the front and is secured by two screws on each
side of the plastic bezel mount, above and below the front rail mounting screws.
Warning: Bezel
mounts are fragile
and should not be
used as handles to lift
the base unit or be
exposed to any other
strong forces.

Installing Disk Drives
To remove drives or trays, simply push in the tab on the drive carrier to unlock the drive latch, pull the latch out
to the open position as seen in Figure 6 below, and then slide the drive or tray out of the disk drive bay.
Figure 6. Array Disk Drive Latch Open Position
To install a drive or tray in an empty drive bay, simply slide the drive or tray into the empty bay with the drive
latch in the open position until the drive latch catches on the inside edge of the drive bay, then move the latch to
the closed position until it locks into place with a click.
While the drive removal and insertion process is simple, there are some general guidelines to keep in mind
when installing and removing disk drives from the array.
Note: All array disk drives should be reseated before the initial startup anytime after the array is transported or
shipped with the drives installed.
The disk drives in positions 00, 01, and 02 function as a system drive stripe set and must remain
mounted and remain in their original positions for proper array operation.
If disk drives in positions 00, 01, or 02 must be replaced, only remove one drive at any given time.
When installing more than one drive while the system is powered on, only install one drive at a time.
Wait until each drive reaches a ready state before installing the next drive.
When replacing failed disk drives, replace each drive with the same drive model.
Use dummy trays in any vacant slots to maintain proper unit air flow.
Cable Connections
This section describes the various connection points used for network and storage connectivity.
SAS Cable Connections
The array SAS ports are used to connect the base unit with additional disk enclosures to expand storage
capacity. When connecting a disk enclosure to the base unit, use an SAS wide-link cable to connect each DP-
IN port on the disk enclosure to the DP0 or DP1 port on the base unit. To connect more than one disk
enclosure, connect the DP-IN on the next disk enclosure to DP-OUT on a previously connected disk enclosure
as shown in Figure 7 below.
