Hardware Overview

The following sections describe the system components of the Sun StorageTek 5220 NAS Appliance with back-end storage.

Sun StorageTek 5220 NAS Appliance

The Sun StorageTek 5220 NAS Appliance is the basic unit. FIGURE 1-1 shows the front of the appliance. You need the software serial number for any calls for service and for adding licenses and you need the hardware serial number if you decide to expand the system.

FIGURE 1-2 shows the back of the appliance. The appliance contains a dual-port fibre channel (F C) host bus adapter (HBA) card in PCI slot 1. The other slot, PCI slot 0, can be empty or contain one of the optional cards, listed in Appliance Options.

Appliance Options

One of the ports on the HBA card in PCI slot 1, HBA Port 2, can be used for connecting to tape backup. Its other port, HBA Port 1, is dedicated to connecting to the controller unit, as shown in FIGURE 3-1.

PCI slot 0 can contain the following options:

A dual-port copper 10/100/1000 Gigabit Ethernet card

A dual-port optical Gigabit Ethernet card

A FC HBA card for tape backup

A SCSI HBA card for tape backup

An uninterrupted power supply device (UPS), using the USB-to-Serial Port Adapter/Convert Cable included in the ship kit. If a power outage occurs, the UPS maintains the operation of the system. If the battery in the UPS loses power, the UPS performs a graceful shutdown of the system. Connecting the UPS adapter cable to a supported local UPS device enables the appliance to monitor the state of the UPS.

Back-End Storage

The RAID controller unit provides direct-attached back-end storage for the Sun StorageTek 5220 NAS Appliance. At a minimum, the system has an appliance and one controller unit containing SATA disk drives.

In addition to the appliance and controller unit, you can set up additional back-end storage by connecting one or two expansion units to the controller unit. Each expansion unit must contain only SATA disk drives. FIGURE 1-5 shows the front of the expansion unit.

Software Overview

The appliance and its back-end storage are configured and managed through the following software components, described in the following sections:

Web Administrator

Administrator Console

Licensed Software Options

Web Administrator

The Sun StorageTek 5220 NAS Appliance ships with the Web Administrator software installed. Other than a standard web browser, you do not need to install any software to manage your system.

The Web Administrator graphical user interface (GUI) lets you configure system parameters through a series of menus and screen panels. These settings are discussed in the Sun StorageTek NAS OS Administration Guide

To access the Web Administrator, your system must be running Microsoft Windows 98/NT/2000/XP/2003, Sun Solaris trademark Operating System (Solaris OS) 5.7 (minimum version), or Red Hat Linux software.

Microsoft Windows users require one of these browsers:

Internet Explorer 5.5 (minimum version) on systems using Microsoft Windows 98/NT/2000/XP/2003

Netscape software 4.77 (minimum version) on systems using Microsoft Windows 98/NT/2000/XP/2003 and Solaris OS. Netscape 6.0 and 6.01 are not supported.

Solaris OS and Red Hat Linux users require one of the following browsers:

Netscape software 4.77 (minimum version) on systems using Microsoft Windows 98/NT/2000/XP/2003 and Solaris OS. Netscape 6.0 and 6.01 are not supported.

Mozilla browser.

Java platform-enabled browser with Java Plug-in 1.4 (minimum version).

Note - To download the latest Java Plug-in, go to http://java.com

Administrator Console

An alternative to the Web Administrator is the administrator console. You can use a number of protocols such as Telnet, SSH, or RLogin to connect to the administrator console as long as the application you use has an ANSI-compatible terminal emulator. The administrator console is described in Appendix A in the Sun StorageTek NAS OS Administration Guide.

Licensed Software Options

You can purchase additional software for the system:

Sun StorageTek File Replicator duplicates data from one volume onto a mirrored volume on a different Sun StorageTek 5220 NAS Appliance or Sun StorageTek 5320 NAS Appliance.

Sun StorageTek Compliance Archiving Software enable volumes to follow advisory or mandatory enforcement of compliance archiving guidelines for data retention and protection.

The options and how to activate them are described in Chapter 9 in the Sun StorageTek NAS OS Administration Guide.
