# 7 Site Planning

This chapter provides planning information and requirements to consider before installation of the SL3000 library. Key planning considerations include:

A site survey which addresses the following issues:

- System configuration: type of customer platform used

- Applications: number and type of system backups, type of backup and archive software, type of library management software (such as ACSLS or ELS/HSC)

- Hardware configuration: library capacity, tape drive type, media type

- Network configuration: connectivity options, required network devices and cables

- Content Management: partitioning plans, workloads and host contention issues

Site preparation:

- Physical space: floor space, ceiling height, placement

- Weight: floor support, weight distribution

- Cabling routes: floor cutouts, cabling runs, conduit type

- Power: source type, required amount

- Environment: airflow, contaminants, fire suppression

- Compatibility: tape drives, media, software, accessory rack

- Expansion: space for additional modules

## Floor Requirements

The SL3000 library can be installed on a raised, solid, or carpeted floor with a smooth surface. There must be adequate airflow and the floor must meet environmental specifications and weight requirements. If the floor is raised, there should not be ventilation panels directly below the library. If the floor is solid, route cables from the ceiling to avoid creating a tripping hazard. If the floor is carpeted, make sure the carpet is approved for computer-room equipment and provides protection from electrostatic discharge (ESD).

### 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.

## Fire Suppression Planning

The library does not ship with a fire suppression system, but features have been incorporated into the library to allow for one. Professional Services can assist with fire suppression planning.

Figure 7-4 Fire Suppression Ceiling Access (Viewed from the top of the library)

- Openings = One per module that measure 5 cm (2 inches) diameter. Do not cut/alter the provided opening without contacting Professional Services.

- Plates = Cover the openings and measure 7 cm (2.75 inches) square and 1 cm (0.48 inches) thick. These plates are what contractors can use to drill in to for a custom fit of the nozzles.

- Screws = Two T25 Torx screws

- Nozzle protrusion into the library to clear robotic operation =1 cm (0.4 inches) from the top of the library

## Cable Routing

The SL3000 library has rear door cut-outs on both the top and bottom of the door to allow for cable routing. The cut-out is a 2.5cm (1 inches) opening that runs 73 cm (29 inches) along the length of the door with cable routing hardware and reliefs available.

Note: There are two square cut-outs on the rear door of the Base and DEM. These are not for cable routing.

When routing cables, make sure to include locations for power, drive interface, library control, and Ethernet cables. As a best practice, route power cables through one cut-out and signal cables through another cut-out.

Figure 7-5 Door Cable Routing Cutouts

Figure 7-6 Rear Door AC PDU Access - Not for Cable Routing

### 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.

## Environmental Requirements

Although the SL3000 library will function over a full range of environmental variables as specified below, for optimal reliability maintain the environment between the recommended ranges. Although this equipment is designed to operate in environmental conditions of 20% to 80% humidity, a recommended industry best practice is to maintain a relative humidity of 40% to 50%.

Table 7-6 Environmental Specifications

Description | Temperature | Relative Humidity (non-condensing) | Wet Bulb Maximum | Maximum Altitude
--- | --- | --- | --- | ---
Operating | 15 to 32°C (60 to 90°F) dry bulb | 20% to 80% | 29.2°C (84.5°F) | 3.05 km (10,000 ft)
Storage | 10 to 40°C (50 to 104°F) | 10% to 95% | 35.0°C (95.0°F) | 3.05 km (10,000 ft)
Shipping | -40 to 60°C (-40 to 140°F) | 10% to 95% | 35.0°C (95.0°F) | 15.24 km (50,000 ft)

### 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.

Caution: Bodily injury and equipment damage: A qualified seismic engineer must be consulted to verify seismic zone exposures and adequate site preparation.

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.
