Chapter 3 Verify Installation Requirements

Steps:

1. Receiving and unpacking.

   A 2-column table displays the height, width, depth and weight of the product. The first column applies to the packaged base rack with shipping pallet. The second column applies to a fully populated base rack without packaging.

   Note

   One should allow enough space around the product to remove the shipping cartons. In addition, the minimum required depth for roll-off is 4.5 meters, or 15 feet. Refer to the Sun Rack II Unpacking Guide (820-5210) included with the packaging for further details.

2. Maintenance clearance.

   A table displays how much maintenance clearance is required at the front, rear and top of the rack, and how much space is required to remove the side panels.

3. Access route to installation site.

   A 2-column table displays the minimum door and elevator dimensions, maximum incline, and minimum loading capacity of the elevator, pallet jack and floor on the route to the installation site. The first column applies to the base rack with shipping pallet. The second column applies to the base rack without shipping pallet.

Steps:

1. Oracle recommends using raised flooring, able to support the total weight of the system including power distribution units (PDUs): 1005 kg, or 2215 lbs).

2. Temperature, humidity and altitude.

   A 3-column table displays the temperature, relative humidity and altitude requirements for the Oracle Virtual Compute Appliance. The first column applies to the system in operating condition. The second column applies to the system in non-operating condition. The third column lists the optimum conditions.

3. Provide adequate ventilation and cooling.

   • Make sure that the capacity of the air conditioning equipment is sufficient for the new system hardware.

   • Respect the maintenance clearance at the front and back of the system for optimum airflow. The air intake is at the front, and the air outlet is at the back.

   • Install perforated floor tiles (approximately 400 CFM/tile) in front of the rack for cold air intake. Use four tiles for a fully populated rack, three tiles for 8-16 compute nodes, or one tile for 8 or fewer compute nodes.

   • Cover empty rack units with filler panels to avoid adverse effects on airflow and cooling.

   An image illustrates the optimum airflow, with cool air flowing up through perforated floor tiles in front of the rack, and traveling through the rack from front to back in order to cool the system.

Steps:

1. Verify that the PDUs installed are correct for your data center power source: 22 or 24kVA for low or high voltage.

2. PDU power cords are 4 meters, or 13.1 feet, long. Up to 1.5 meters, or 4.9 feet, is routed within the rack cabinet. AC power receptacles must be within 2 meters, or 6.6 feet, of the rack.

3. Use dedicated AC breaker panels for all power circuits that supply power to the PDU.

4. Use dedicated AC breaker panels for all power circuits that supply power to the compute nodes. Compute nodes require electrical circuits to be grounded to the Earth.

   Note

   Circuit breakers are supplied by the customer. One circuit breaker is required for each power cord.

5. In addition to circuit breakers, provide a stable power source, such as an uninterruptable power supply (UPS) to reduce the possibility of component failures.

6. Racks are shipped with grounding-type power cords (three-wire). Always connect the cords to grounded power outlets. Verify the correct grounding method for your location.

Steps:

1. Four ports (2x2) on redundant next-layer switches in the data center must be reserved to connect the 10GbE public network ports of the IO Director switches.

2. A terminal or workstation with a web browser must be connected to the management network.

3. Three IP addresses in the public network must be reserved for management node configuration.

4. The following network configuration details are required.

   A table describes the network configuration properties required during the initialization of the Oracle Virtual Compute Appliance. An empty column provides space for the administrator to write down the network-specific entries.
