[. . . ] HP High Performance Clusters LC Series Setup and Installation Guide March 2004 (Second Edition) Part Number 341524-002 © 2004 Hewlett-Packard Development Company, L. P. Hewlett-Packard Company shall not be liable for technical or editorial errors or omissions contained herein. The information in this document is provided "as is" without warranty of any kind and is subject to change without notice. The warranties for HP products are set forth in the express limited warranty statements accompanying such products. [. . . ] You should also consider providing a backup power source such as an Uninterruptible Power Supply (UPS). A properly designed computer room has adequate ventilation and cooling for racks with servers and storage devices and has the appropriate high-line power feeds installed. For more information on datacenter design and planning, please refer to Technology Brief TC030203TB at the link below. This technology brief describes trends affecting datacenter design, explains how to determine power and cooling needs, and describes methods for cost-effective cooling.

Depending on the size of the cluster ordered, the shipment can consist of from one to four 42U racks. More racks could be contained in the shipment if additional storage options are ordered as well. Every configuration is shipped fully integrated with easy to read cable labels to facilitate the cabling process. HP High Performance Clusters LC Series Setup and Installation Guide 11 Step 3: Positioning the Racks Upon receipt of the HPC LC Series solution, the racks will need to be carefully transported from the receiving area to the data center. Be sure to follow all unpacking, transporting, and safety instructions included with the product. When selecting the final position of the racks, be sure to place them in sequential order, beginning with Rack 1 on the left as viewed from the front of the racks. The cable lengths provided are designed for that relative position. For example, figure 1 below illustrates the proper rack positioning of a 128-node cluster solution. The rack number is located on a label at the top rear of the cabinet. Figure 1: Rack positioning for an HPC LC Series cluster solution The following spatial needs should be considered when deciding where to physically place the HPC LC Series cluster solutions: · · Clearance in front of the rack unit should be a minimum of 50 inches (127 cm) to allow for adequate airflow and serviceability. Clearance behind the rack unit should be a minimum of 30 inches (76. 2 cm) to allow for adequate airflow and serviceability; 50 inches (127 cm) is recommended. 12 HP High Performance Clusters LC Series Setup and Installation Guide Rack Power Each fully configured rack in an LC Series cluster reference design comes with three 24-Amp (Americas region) or 32-Amp (European regions) High Voltage Power Distribution Units (PDUs). The data center will need to be configured to support this amount of power and power cabling. Power units supplied for other regions or to unique customer specifications may come with alternative PDUs. This should be reviewed prior to receiving the cluster to be sure that the data center is properly equipped. Rack Cooling The racks in each HPC LC Series solution draw cool air in through the front and exhaust warm air out of the rear. To ensure continued safe and reliable operation of the equipment, place the system in a well-ventilated, climate-controlled environment. A minimum of 50 inches (127 cm) is needed in front of the rack for adequate cooling and servicing. A minimum of 30 inches (76. 2 cm) is required behind the rack for adequate cooling and servicing, but 50 inches (127 cm) are recommended. The HPC LC Series solutions should be placed in data centers with an adequate air-conditioning system to handle continuous operation of this solution. [. . . ] If the cluster was shipped with an operating system installed, the server will boot to the OS. Once it has been confirmed that the server boots properly you can continue to set up the control node to your operating system and applications specifications. Refer to the operating system and software vendor's installation instructions for additional information. Visually check each NIC Link light on the server and the switches to which they connect to verify that each cable has a link established. [. . . ]
