INTRODUCTION

PackagingInformation

The StorCase Technology InfoStation external expansion chassis is shipped in a container
designed to provide protection and prevent damage during shipment, as confirmed by the
International Safe Transit Association (ISTA Procedure 1A). The InfoStation was carefully
inspected before and during the packing procedure at the factory. Evidence of any damage
to the InfoStation should be reported to the shipper immediately.

If the wrong InfoStation model has been received, please call your reseller or StorCase at
[phone] to arrange for a Return Material Authorization (RMA). StorCase cannot ac­cept returns which do not display an RMA number on the outside of the package. Return the
unit with all the original packing materials.

Before removing any component from its packaging, discharge any static electricity by
touching a properly grounded metal object.

Serial Number

The InfoStation is labeled with a serial number. This number must be reported to the StorCase
Customer Service Representative in order to receive a Return Material Authorization (RMA)
for warranty claims. Locate the serial number label and record the number in the space
provided below.

GeneralDescription

CAUTION: The InfoStation chassis contains NO USER SERVICEABLE parts inside the unit.

NOTES: The configuration and use of the InfoStation RAID Controller requires a certain

InfoStation 12-bay SCSI-to-Serial ATA and FC-to-Serial ATA RAID enclosures are designed
to support low-profile Serial ATA (SATA) or Parallel ATA (Ultra ATA/100) drives for RAID
applications. The SCSI-to-SATA enclosures support dual SCSI Ultra160 host channels and
are downward-compatible with earlier SCSI Wide Single-Ended or LVD interface technologies
(i.e. Ultra2 or Ultra). Daisy-chaining chassis for extended storage is also possible with an
optionally available SCSI Ultra160 repeater kit. The FC-to-SATA enclosures support dual Fibre
Channel Arbitrated Loops (FC-ALs) with 2Gbps operation.

Each standard 4U rack mount 12-bay RAID InfoStation chassis comes equipped with a RAID
controller, (12) removable drive carriers and an open 5.25" half-height device bay. These
enclosures are constructed of corrosion-resistant steel and each include (2) hot-swappable,
redundant 460W power supply modules and (2) hot-swappable, redundant, variable-speed
fan modules.

Both the SCSI-to-SATA and FC-to-SATA RAID chassis support RAID levels 0, 1, 0+1, 3 and
5, and is OS independent. Online Capacity Expansion (OCE) and LUN support, 128MB cache
memory, as well as automatic hot swap, hot spare and drive rebuild support are all included.
An audible alarm on the InfoStation alerts the User to system hardware failures and warning
conditions. LED indicators at each drive bay provide additional User feedback for drive activity,
drive readiness and drive faults.

Refer ALL servicing to qualified personnel!

level of expertise and experience on the part of the user/integrator. Since there
are many configuration options and variables (ie. host platforms, applications,
etc.), only general guidelines will be discussed in this User's Guide.

Refer to the disk manufacturer's documentation for specific information re­garding the disks.

The InfoStation also incorporates "Soft Start" circuitry which eliminates in-rush current to each
of the installed drives during spin-up, as well as avoid power arcing during drive insertion.

A User Interface Module on the 12-bay InfoStation provides the User with a visual indication
of chassis configurations and communication statuses, in addition to providing an RS232
connection for system environmental monitoring, configuration and control. InfoMon®, a
downloadable chassis monitoring utility program, provides the InfoStation with a customizable,
web-based monitoring capability via the RS-232 serial connection. InfoMon includes a Call
Home feature, which enables chassis log information to be conveniently sent to a predeter­mined FTP site for trouble shooting and analysis. InfoMon also provides the User the ability to
easily configure both device and chassis settings with a few clicks of the mouse! Refer to
Appendix B for further information on InfoMon.

StorCase Technology, Inc. InfoStation 12-Bay RAID User's Guide - C00

Introduction 3

The latest versions of the InfoMon utility program and User's Guide can be downloaded (free
of charge) from the StorCase web site (http://www.storcase.com). Contact StorCase for
further information. Refer to Appendix B for further information on optional InfoStation
accessories.

Using a modular approach supported by redundant features and hot swapping capabilities,
the InfoStation will provide continued data availability and allow for ease of maintenance and
minimal system down time.

The modular and scalable design of the InfoStation chassis also allows a variety of future
product upgrades to be offered. Upgrade modules (such as SNMP) are anticipated InfoStation
options.

This User's Guide describes the steps required for installing drive(s) into the InfoStation
external expansion chassis. This guide is intended to supplement documentation provided with
the host computer system, the operating system, and the drive(s) to be installed within the
InfoStation.

RAID Controller Configuration 17

Mode Operation

The SCSI-to-SATA RAID Controller operates in three (3) modes:

 Self-Diagnostic Mode

 Configuration Mode

 Operation Mode

Self-Diagnostic Mode

To ensure flawless operation, the RAID Controller has a built-in self-diagnostic utility. Self­Diagnostic Mode occurs automatically upon power up, or after the RAID Controller has been
reset. During this mode, all components are tested and any potential problems are reported.

The Self-Diagnostic Mode runs three major diagnostic tests. The first diagnostic includes
testing the CPU and supporting core logic chips, the internal bus, memory, SCSI controller,
SATA controllers, and RS-232 controllers. The second diagnostic tests for the presence of
disks on each individual disk channel. It also checks the functionality of each disk found. The
final diagnostic tests the RAID functionality.

Configuration Mode

NOTE: The RAID Controller should be OFFLINE (disconnected from the host system)

Configuration Mode may be selected whenever the Enter button is pressed during Operation
Mode or when the Monitor Utility is invoked from the remote terminal. In Configuration Mode,
the user is able to modify the settings of the RAID Controller and perform different functions
to the controller.

Entering a Password

If the password-check feature is enabled, the user will be prompted to enter a password
before proceeding (the default password is "00000000"). Refer to section "4 Password
Security" for information on how to change the default password.

The user may use the front control panel buttons to enter the password. Use the ê and é
keys to scroll through the available characters, then use the Enter button to select the
character and move to the next position. Once all the characters have been entered, press
the Enter button to access the Configuration Mode.

InfoStation Monitoring Utility (InfoMon®)

InfoMon is a web-based monitoring utility that runs under the Windows O/S. This free utility
(and its accompanying User's Guide) is available for download at the StorCase web site
(http://www.storcase.com).

The primary purpose of InfoMon is to continuously monitor the environmental status and
indicate alarm conditions inside the InfoStation chassis via a serial connection to a PC. InfoMon
also provides the User the ability to easily configure both device and chassis settings with
a few clicks of the mouse!

In addition, InfoMon allows the User to monitor the statuses and temperatures of individual
InfoStation modules and drive bays, etc., and can provide "real-time" updates via an Internet
connection. With the recent addition of the InfoMon Call Home feature, this information can
also be sent to a specific site for access by StorCase technical support staff in order to assist
with system troubleshooting. The Call Home feature also provides the ability to set-up a paging
function for notification of environmental alarm or warning conditions.

To install and operate the InfoMon software, the computer system must meet the following
requirements:

Operating System: Microsoft® Windows® 95/98/NT/2000/XP
CPU: IBM-compatible 486 or higher
Memory: 32MB RAM
Hard Disk Space: 12MB
Internet Connection: Required only if monitoring via the web
Internet Browser: Microsoft Internet Explorer 5.0 (or higher) or

Netscape Communicator 4.7 (or higher)

SCSI Problems (For SCSI-to-SATA version only)

 The RAID Controller is not properly identified by the SCSI adapter during

initialization of the computer system.

Cause - SCSI ID set for the RAID Controller could be the same ID used by another SCSI device

Fix - Select a different SCSI ID for the RAID Controller. Most SCSI host adapters provide

attached to the same SCSI host adapter.

onboard ROM BIOS (or software utility) that displays attached devices and their SCSI
IDs. Disconnect the RAID Controller from the SCSI host adapter during system boot
and note the SCSI IDs already in use.

 The RAID Controller is identified at all SCSI IDs.

Cause - SCSI ID set for the RAID Controller could be identical to the reserved SCSI ID used

Fix - Configure the RAID Controller to a different SCSI ID. Most SCSI host adapters reserve

by the SCSI host adapter.

SCSI ID7.

 The RAID Controller is not detected by the SCSI host adapter.

Cause - Incorrect termination in the daisy-chain configuration, or possibly a loose SCSI

Fix - For daisy-chain configurations, verify that only the SCSI host adapter and the last

cable.

SCSI device is terminated.
