7 Site Planning

Base Module

^Footnote 1 Minimum transportation clearance. There are alignment tabs on each side of the module, which add 4.5 cm to the 76.8 cm width of the module. Therefore, 81.3 cm is the minimum transportation width.

^Footnote 2 One side cover adds 7.4 cm (2.9 in.) to the width of the module. Only the ends of the library require side covers.

Drive Expansion Module

^Footnote 1 Minimum transportation clearance. There are alignment tabs on each side of the module, which add 4.5 cm to the 76.8 cm width of the module. Therefore, 81.3 cm is the minimum transportation width.

Cartridge and Parking Expansion Modules

^Footnote 1 Minimum transportation clearance. There are alignment tabs on each side of the module, which add 4.5 cm to the 76.8 cm width of the module. Therefore, 81.3 cm is the minimum transportation width.

Access Expansion Module

^Footnote 1 Minimum transportation clearance. There are alignment tabs on each side of the module, which add 4.5 cm to the 91.5 cm width of the module. Therefore, 96 cm is the minimum transportation width.

Covers, Doors, and Service Clearances

Weight

Ensure the site floor can support the weight of the library. If the equipment must be transported on elevators, the elevator cars must be capable of safely handling the weight. Depending on the library configuration the weight of the library can vary (see "Physical Dimensions and Weights").

Weight Distribution Pads

The site floor must be capable of supporting 454 kg (1,000 lb) per weight distribution pad, which measure 4 by 8 inches. The distribution pads are represented by the dark grey boxes in the figure below.

Figure 7-3 Location of Weight Distribution Pads

Floor Slope

TallBots must travel along a level plane throughout the library. Any excessive out-of-plane conditions could cause binding, premature wear, and damage to the TallBots. Use the jack pads to adjust the library on a sloped floor.

AC Power Configurations and Cables

SL3000 libraries require that the customer select one of the following single phase AC power options for the base and drive expansion modules:

• 110 VAC, 50/60 Hz, at 20 Amps (range: 100–127 VAC, 50–60 Hz, 16 Amps)

• 240 VAC, 50/60 Hz, at 30 Amps (range: 200–240 VAC, 50–60 Hz, 24 Amps)

Make sure to plan for the locations of power cables and list the locations for their associated circuit breakers. Cables must be ordered for the appropriate power configuration. Keep in mind that you must order one power cord per PDU installed:

• N+1: One power cord for the Base and an additional power cord for the DEM (if installed).

• 2N or 2N+1: Two power cords for the Base and two additional power cords for the DEM (if installed).

Library Network Cables

The maximum distances that the SL3000 Tape Library supports on a Fibre Channel link is determined by the link speed, the type of fiber (50 or 62.5 micron), and the device to which the library is attached.

The library can be used in a 62.5-micron-cable Storage Area Network (SAN). However, the cable that connects the library to the network must be a 50-micron cable because the library uses 50-micron cables internally.

Refer to your switch vendor to determine what is supported in the customers storage area network. The typical support distances for the cables are:

• 4 Gbps = up to 70 m (230 ft) for 62.5-micron, 150 m (492 ft) for 50-micron

• 2 Gbps = up to 150 m (492 ft) for 62.5-micron, 300 m (984 ft) for 50-micron

• 1 Gbps = up to 175 m (574 ft) for 62.5-micron, 500 m (1640 ft) for 50-micron

If your library attaches to a host bus adapter (HBA), refer to the documentation for the HBA for the supported cable distances. A list of cables is supplied in "Cables - Fibre Channel, ESCON, and Ethernet".

Tape Drive Cables

A list of cables is supplied in "Cables - Fibre Channel, ESCON, and Ethernet". If the drives are connected to the optional Ethernet switches (see "Encryption Switches and Cabling") to connect to the drives, the cable connections between each drive and the switch are at the rear of the base or drive expansion modules.

Power Consumption

For information on power requirements, heat output, and power consumption, refer to Chapter 5, "Power and Cooling".

Seismic or Earthquake Ratings

The requirements for seismic compatibility vary dramatically throughout the world. Therefore, Oracle does not offer a standard "seismic" feature for the SL3000 library. It is recommended that any customer who has seismic concerns work with local experts who are familiar with the local code and requirements. Professional Services can also be engaged to help coordinate this activity.

For sites in areas of seismic activity, the customer may wish to permanently fix the library position for added stability. The SL3000 library provides mounting holes in the floor of each module where half-inch carriage bolts (mounting studs) can be used to permanently fix the library's position.

Airborne Contaminants

Control over contaminant levels in a computer room is an extremely important consideration when evaluating an environment. Automated tape library components and electronics, tape drives, and media are subject to damage from airborne particulates. The operating environment must adhere to the requirements of: ISO 14644-1 Class 8 environment.

For more information refer to Appendix C, "Controlling Contaminants".

Gasses that are particularly dangerous to electronic components include chlorine compounds, ammonia and its derivatives, oxides of sulfur and petrol hydrocarbons. In the absence of appropriate hardware exposure limits, health exposure limits must be used.

Humidification with chlorinated water is a common source of damaging airborne chlorine. Appropriately designed carbon filters must be used to ensure safe levels of airborne chlorine when chlorinated water is used for humidification.
