Site Planning

This chapter outlines the site-planning requirements and basic safety requirements for the installation and use of Sun StorEdge 3320 SCSI arrays. Customers are asked to complete a Section 2.8, Preinstallation Worksheet and to prepare the site for installation according to the worksheet details and the specified site-planning requirements.

Review the details of this chapter before installing a Sun StorEdge 3320 SCSI array. Topics covered in this chapter are:



Note - Refer to the Sun StorEdge 3320 SCSI Array Release Notes for the current lists of supported operating systems, host platforms, software, and qualified cabinets.



2.1 Customer Obligations

The customer is obliged to inform Sun Microsystems, Inc. of any and all ordinances and regulations that would affect installation.



caution icon Caution - When selecting an installation site for the Sun StorEdge 3320 SCSI array, choose a location that avoids excessive heat, direct sunlight, dust, or chemical exposure. Such exposure greatly reduces the product’s longevity and might void your warranty.


The customer is responsible for meeting all government codes and regulations concerning facilities. The customer is also responsible for compliance with the following requirements:


2.2 Safety Precautions

For your protection, observe the following safety precautions when setting up your equipment:

2.3.1 Electromagnetic Compatibility (EMC)

The following is required for all installations:


2.4 Electrical and Power Specifications

All Sun StorEdge 3320 SCSI arrays require two independent power sources. Each array has two power-supply-and-fan modules for redundancy.

Each Sun StorEdge 3320 AC array requires two 115-VAC/15A or two 240-VAC service outlets. All AC power supplies are autoranging and are automatically configured to a range of 90 to 264 VAC and 47 to 63 Hz. There is no need to make special adjustments.

Each DC array requires two -48 VDC service outlets, and has an input voltage range of -36 VDC to -72 VDC.



Note - To ensure power redundancy, connect the two Sun StorEdge 3320 SCSI power modules to two separate circuits (for example, one commercial circuit and one UPS).

Dimensions

2U (3.5-in. ) height

20-in.(50.8 cm) chassis depth

17.5-in.(19 in.with ears) width

Installation clearances

For FRU removal and replacement, 15-in. (37 cm) is required front and back.

Cooling clearances

6-in. (15 cm) is required front and back. No cooling clearance is required on the sides or the top and bottom of the array.



2.6 Layout Map

It is helpful to create a sketch or layout map to indicate the exact location for the Sun StorEdge 3320 SCSI array installation as well as the location of the hosts, console, and Ethernet connections that will be connected to it.

As you lay out the components, consider the cable lengths that will be used.

2.6.1 Rack Placement

Follow these guidelines when preparing a rackmount placement for your system.

2.6.2 Tabletop Placement

Sun StorEdge 3320 SCSI arrays can be positioned on a desk or a table. Follow these guidelines when preparing a tabletop placement for your system.


2.7 Console and Other Requirements

A console with at least one serial port connection is necessary for installation and configuration of your Sun StorEdge 3320 SCSI array. Once you have configured your array with an IP address, an Ethernet port can also be useful for configuring the array.



Note - Sun StorEdge 3000 family arrays require at least CAT-5 Ethernet cable.


See the following preinstallation worksheet for additional preparation details.


2.8 Preinstallation Worksheet

When ordering a Sun StorEdge 3320 SCSI array, complete the following preinstallation worksheet and then prepare the site for installation according to the site-planning requirements.

You are responsible for ensuring that the site consistently conforms to all stipulated standards, and that necessary peripherals are made available to the engineer during installation.

Review the details of your specific survey before installing your Sun StorEdge 3320 SCSI array.

If necessary, attach or sketch a network diagram to the survey.
