1.1 Introducing the Array Models

The Sun StorEdge 3310 SCSI array models include:

A redundant array of independent disks (RAID) with a single controller

A RAID with two controllers

An expansion unit or JBOD (an array with disks and no controller)

Providing up to 432 GB RAID based on 36 GB drives in an amazingly small footprint (3.5-inch tall by 19 inches wide) storage unit, the Sun StorEdge 3310 SCSI RAID array is a high-performance, storage device that contains one or two internal RAID controllers and up to twelve disk drives with SCSI connectivity to the data host.

Highly scalable, the RAID-equipped array supports up to two expansion chassis (expansion unit arrays that have a set of drives and no controller) for a total of 36 drives. The RAID array and expansion units connect to the storage devices and consoles via standard serial port, Ethernet, and SCSI connections.

Also available is a JBOD array (Just a Bunch of Disks), which is similar to an expansion unit except that it is connected directly to a host server rather than to a RAID array.

Extensive reliability, availability, and serviceability (RAS) features include redundant components, notification of failed components, and the ability to replace components while the unit is online.

The RAID array can be used either as a standalone storage unit or as a building block, interconnected with expansion arrays of the same type. The array can be placed on a tabletop or rackmounted in a server cabinet or expansion cabinet.

For information about specifications and agency approvals, refer to Appendix A, SCSI Array Specifications.

1.2 Task Map

The following task map outlines the key steps for installing, configuring, and managing the array.

Read Release Notes

Before beginning the installation, review the release notes for late-breaking news and updates, located at:
http://www.sun.com/products-n-solutions/hardware/docs/Network_Storage_Solutions/Workgroup/3310

Prepare Site and Plan Configuration

Prior to installation, you must review important safety guidelines in the Sun StorEdge 3000 Family Safety, Regulatory, and Compliance Manual.

To prepare the site and plan the array configuration, refer to:

Sun StorEdge 3000 Family Array Installation, Operation, and Service Manual
Sun StorEdge 3000 Family Best Practices Manual

Prepare Host System

Install up to two HBA adapters in the host system(s). Refer to the documentation that came with your host adapter and system for instructions.

Install Hardware

Install the Sun StorEdge 3310 SCSI Array on a desktop or in a rack. Refer to this manual for instructions, and to the Sun StorEdge 3000 Family Rack Installation Manual for 2U Arrays (816-7320).

For additional firmware instructions, refer to Sun StorEdge 3000 Family RAID Firmware User's Guide (816-7296).

Install Software

Optionally install any or all of the software applications from the Professional Storage Manager CD, and use the following guides.

Sun StorEdge 3000 Family Configuration Service User Guide
Sun StorEdge 3000 Family Diagnostic Reporter User Guide

1.3 Additional Software Tools

The following additional software tools are available on the Sun StorEdge Professional Storage Manager CD-ROM, provided with your array:

Sun StorEdge Configuration Service, a management and monitoring program

Sun StorEdge Diagnostic Reporter software, a monitoring utility

Sun StorEdge CLI, a command line utility to manage the array.

The Sun StorEdge 3310 SCSI Array Documentation CD-ROM provides the related user guides with detailed installation and configuration procedures for these tools.

For other supported software tools, refer to the release notes for your array, located at:
