Introduction
Manual No. 771929 1-5
Global Array Manager Server Overview
Global Array Manager Server software Version 2.21 (GAM Server Version
2.21) is an enhancement of the server application used to manage disk array
subsystems attached to a Mylex Disk Array Controller.
Monitoring Functions
The Global Array Manager Server software collects and disseminates
information on disk array status and resource utilization. The Global Array
Manager Client software, an optional component available from Mylex,
organizes this information through an intuitive graphical display. In addition,
GAM Server monitors the characteristics and performance of supported
SCSI Host Bus Adapters.
SNMP/DMI Support
The Global Array Manager Server software includes SNMP and DMI
support, allowing stand-alone monitoring of performance and fault
information. This is useful if a management package is already in use.
Support for these protocols includes “read only” functions. Write functions
are only available through use of the optional Global Array Manager Client
software.
Management Functions
The Global Array Manager Server software executes the management
instructions specified by the Global Array Manager Client. GAM Server
software offers fault management, reliable messaging, and superior
operating system support. Global Array Manager Client software manages
or performs maintenance on individual disk arrays and drives (with the
appropriate authentication), again by means of the graphical user interface.
Configuration Functions
Disk array configuration and remote TCP/IP support functions are provided
through use of the Global Array Manager Client software. If your goal is
monitoring and simple maintenance or messaging, Global Array Manager
Server is sufficient for these tasks.

Requirements

Requirements
Requirements for Disk Array Controller Operating System
Drivers and Utilities
It is assumed that the hardware installation, the system configuration, and the
disk array controller configuration are properly completed. If they are not,
please refer to the appropriate Mylex Disk Array Controller Installation
Guide and to the RAID EzAssist Configuration Utility Reference Guide.
Complete the required procedures described in those manuals before
proceeding with installation of drivers and utilities discussed herein.
The person who will be performing the installation must have
SUPERVISOR or ADMINISTRATOR rights for the system onto which
these software drivers will be installed.
It may also be necessary to prepare a DOS bootable floppy disk to be able to
perform certain procedures described in this manual. Before starting, be sure
to read through all applicable instructions to determine the specific
requirements for each operating system to be supported.
Requirements for Global Array Manager Server Software
The correct environment must be present on the server for the Global Array
Manager Server software to work properly. The environment is a
combination of hardware and software which meets the following
requirements:
Server Hardware and Software - NetWare

• 1 MB of free system memory after all volumes are mounted
• 2 MB of free hard disk space on the SYS: volume
• Properly installed and configured Mylex Disk Array Controller with
the appropriate NetWare drivers
• CLIB.NLM version 3.12 dated May 19, 1993 or later
• (Optional) If SNMP participation is desired, SNMP support (available
from third parties) should be installed.
• TCP/IP must be installed.

Introduction
Manual No. 771929 1-7
Server Hardware and Software - Windows NT
• A server running Microsoft Windows NT 4.0
• 2 MB of free hard disk space
• Properly installed and configured Mylex Disk Array Controller with
the appropriate Windows NT drivers
• (Optional) If SNMP participation is desired, system should be
configured with SNMP services.
• TCP/IP must be installed.
Server Hardware and Software - SCO UNIX
• A server running SCO UNIX (version 5.x)
• 2 MB of free hard disk space
• Properly installed and configured Mylex Disk Array Controller with
the appropriate SCO UNIX drivers
• (Optional) If SNMP participation is desired, SNMP support should be
installed.
• TCP/IP must be installed.
Server Hardware and Software - UnixWare
• A server running SCO UnixWare (version 2.0.1 or higher)
• 2 MB of free hard disk space
• Properly installed and configured Mylex Disk Array Controller with
the appropriate UnixWare drivers
• (Optional) If SNMP participation is desired, SNMP support should be
installed.
• TCP/IP must be installed.
