NAS 50/100 Quick Start Guide
This document guides a knowledgeable user through the basic setup of an SGI InfiniteStorage
NAS 50/100 system. Unless otherwise negotiated, your network-attached storage (NAS) system
comes racked and cabled. You only need to configure the NAS software management services.
Professional assistance with the setup of your new NAS solution is available through SGI
Managed Services. If you ordered such service, please contact the SGI Customer Support Center
to schedule the on-site visit.
For more information on the hardware/software used with the SGI InfiniteStorage NAS 50/100,
see “Documentation” on page 22.
This quick start guide as well as other SGI documents can be accessed and downloaded from the
SGI publications library:

Hardware Overview
Your NAS system consists of the following hardware elements:
• A System Management Unit (SMU), either internal or external, depending on system
configuration
• SGI InfiniteStorage NAS 50/100 server(s), referred to as IS-NAS server(s)
• Storage subsystem, which includes the storage array controllers and/or drive trays populated
with disk drives
• Fibre Channel (FC) switch, depending on system configuration
• Private management network
• Public data network
The IS-NAS server is a highly scalable and modular NAS server with multi-gigabit throughput
from network to disk.
IS-NAS Server Front Controls and Indicators

IS-NAS Server Rear Panel–LEDs and Buttons
As shown in Figure 1-3, the rear panel of an IS-NAS server contains three status LEDs that
indicate server status and two buttons that are used to power up and reset the server.
Figure 1-3 Rear Panel LEDs and Buttons
The NVRAM, Power, and Server LEDs indicate if the server is powered on, its operation state,
and if the NVRAM is currently being protected by battery backup power. Table 1-3, Table 1-4,
and Table 1-5 describe the various states of the LEDs.

RAID Controller/Drive Enclosure Rear Panel
Note that controller A (left side of enclosure) contains drive channel 1, while controller B (right
side of enclosure) contains drive channel 2. Figure 1-4 shows the controller’s input/output ports.

2. Fibre channel server host ports
3. Expansion ports
Figure 1-4 RAID Drive Enclosure Rear Panel (SAS Dual-Controller Shown)
Drive Expansion Enclosure Rear Panel
The drive expansion enclosure connects to the RAID expansion enclosure(s) using serial-attached
SCSI (SAS) cables (rather than fibre channel). Each RAID controller has one drive expansion
connector (located on the far right of the controller). You can connect up to three optional drive
expansion enclosures to your RAID controller/drive enclosure. Drive expansion modules (see
Figure 1-5) use the following SAS connectors:
1. SAS in connector
2. SAS out connector
Figure 1-5 Drive Expansion Enclosure Rear Panel

System Indicators
Expansion drive enclosures cable to the primary disk enclosure. The RAID controller/drive
enclosure has a set of indicators on the front-left side that help you determine the operational status
of the unit, see Figure 1-6.

Each RAID enclosure or drive expansion enclosure holds up to 12 sled-mounted removable hard
drives. At least two drives must be installed in the enclosure for it to operate.

Powering On an IS-NAS Server
To power on a server or cluster, do the following:
1. Verify that all servers are switched off.
2. Beginning with expansion enclosures, start all storage subsystems.
3. Wait until the disk LEDs on all of the expansion enclosures have stopped blinking (which
indicates that they are spinning up) or two minutes, whichever comes first.
4. Start the storage subsystem RAID controller enclosures.
The disk drives in some storage enclosures will not spin up until commanded to do so by the
RAID controller. Consequently, the LEDs of those drives may continue to blink until after
the RAID controller enclosure has sent those commands and the drives have spun up.
5. For a cluster configuration, or when using an external System Management Unit (SMU),
start the SMU by depressing the red button located on the right of the unit.
6. Wait one minute to allow the external SMU to start.
7. Power up the IS-NAS server or the first node in the cluster.
To switch the power on for a server/node:
• If the power cables are not connected to the PSU, plug in the power cables. If, after 10
seconds, the PSU LEDs are lit but the Power Status LED on the rear panel is not lit,
press the PWR button to restore power to the system boards.
• If the power cables are connected to the PSU, press the PWR button on the rear of the
server.
The power button may be used to restore power to the system when the server is in a standby
power state. Normally, when power cables are connected to the PSUs, the server will power
up immediately. If, after 10 seconds, the LEDs on the power supplies are lit but the Power
Status LED is not lit, press the PWR button to restore power to the system.
Note: Do not use the PWR button during normal operation of the server. Pressing this button
will cause an improper shutdown: it immediately powers down the system, but the PSUs and
system fans will continue to run.
8. If you are starting a cluster, wait 5 to 10 seconds before powering on the next node in the
cluster.

12 007-5621-001
Software Configuration
After your IS-NAS server is powered on, you can then configure the Software Management Unit
(SMU), a web-based GUI to administer your IS-NAS server. This section describes how you
access the web manager SMU and the items to be configured.
Accessing the Web Manager SMU
You can use one of the following web browsers to access the web manager SMU:
• Microsoft Internet Explorer 7.0 (or later)
• Mozilla Firefox 1.5 (or later)
Some advanced features of SMU require Sun Microsystem’s Java Runtime Environment 5.0
Update 6 or later.
To access the web manager SMU, do the following:
1. Connect a cross-over ethernet cable from a laptop or PC to the primary ethernet port (Port 0)
on the IS-NAS server. See Figure 1-10.
Figure 1-10 Ethernet Connections on the IS-NAS Server
2. Launch a web browser to the following URL:
https://192.168.31.101
You may need to temporarily reset the IP address of the laptop or PC to 192.168.31.1 for this
to work correctly. Figure 1-11 shows the login screen.

:
007-5621-001 13
Note: The IS-NAS server may take two to three minutes (after the start of the power-up sequence)
to fully come online and be reachable via your browser.
