    Power requirements

    Plan your rack and system placement using these component power requirements.

    Unity 2U disk processor enclosure (DPE)

    The input current, power (VA), and dissipation per enclosure listed in this document are based on measurements of fully configured enclosures under worst-case operating conditions. Use the operating maximum values to plan the configuration of your storage system. These values represent either:

    • values for a single power supply line cord, or
    • the sum of the values shared by the line cords of the combined power supplies in the same enclosure, with the division between the line cords and supplies at the current sharing ratio (approximately 50% each).

    Use the provided power and weight calculator to refine the power and heat values in the following tables to more-closely match the hardware configuration for your system.

    A failure of one of the combined power supplies per enclosure results in the remaining power supply supporting the full load. You must use a rackmount cabinet or rack with appropriate power distribution, and have main branch AC distribution that can handle these values for each enclosure in the cabinet.

    All power figures shown represent a worst case product configuration with max normal values operating in an ambient temperature environment of 20°C to 25°C.

    The chassis power numbers provided may increase when operating in a higher ambient temperature environment.

    1 - See Table 16 for system behavior at high ambient temperatures. 2 - The allowable relative humidity level is 20 to 80% noncondensing. However, the recommended operating environment range is 40 to 55%. To minimize the risk of hardware corrosion and degradation, we recommend lower temperatures and humidity for data centers with gaseous contamination such as high sulfur content. In general, the humidity fluctuations within the data center should be minimized. We also recommend that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility. For facilities below 40% relative humidity, we recommend grounding straps when contacting the equipment to avoid the risk of electrostatic discharge (ESD), which can harm electronic equipment.
    NOTICE   For systems mounted in a cabinet, the operating limits listed above must not be exceeded inside the closed cabinet. Equipment mounted directly above or below an enclosure must not restrict the front-to-rear airflow of the storage system. Cabinet doors must not impede the front-to-rear airflow. The cabinet must exhaust air at a rate that is equal to or greater than the sum of the exhaust rates of all the equipment mounted in the cabinet.

    DPE airflow

    The enclosure uses an adaptive cooling algorithm that increases/decreases fan speed as the unit senses changes to the external ambient temperature. Exhaust increases with ambient temperature and fan speed, and is roughly linear within recommended operating parameters. Note that the information in the table below is typical, and was measured without cabinet front/rear doors that would potentially reduce front-to-back air flow.

    Environmental recovery

    If the system exceeds the maximum ambient temperature by approximately 10°C (18°F), the storage processors (SPs) in the system begin an orderly shutdown that saves cached data, and then shut themselves down. Link control cards (LCCs) in each DAE in the system power down their disks but remain powered on. If the system detects that the temperature has dropped to an acceptable level, it restores power to the SPs and the LCCs restore power to their disks.

    Air quality requirements

    The products are designed to be consistent with the requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental Standard Handbook and the most current revision of Thermal Guidelines for Data Processing Environments, Second Edition, ASHRAE 2009b.

    Cabinets are best suited for Class 1 datacom environments, which consist of tightly controlled environmental parameters, including temperature, dew point, relative humidity and air quality. These facilities house mission-critical equipment and are typically fault-tolerant, including the air conditioners.

    The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the data center should be filtered with a MERV 11 filter or better. The air within the data center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.

    The allowable relative humidity level is 20 to 80% non condensing, however, the recommended operating environment range is 40 to 55%. For data centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.

    For facilities below 40% relative humidity, it is recommended to use grounding straps when contacting the equipment to avoid the risk of Electrostatic discharge (ESD), which can harm electronic equipment.

    As part of an ongoing monitoring process for the corrosiveness of the environment, it is recommended to place copper and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity), in airstreams representative of those in the data center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process put in place.

    Storage time (unpowered) recommendation: do not exceed 6 consecutive months of unpowered storage.

    Fire suppressant disclaimer

    Fire prevention equipment in the computer room should always be installed as an added safety measure. A fire suppression system is the responsibility of the customer. When selecting appropriate fire suppression equipment and agents for the data center, choose carefully. An insurance underwriter, local fire marshal, and local building inspector are all parties that you should consult during the selection of a fire suppression system that provides the correct level of coverage and protection.

    Equipment is designed and manufactured to internal and external standards that require certain environments for reliable operation. We do not make compatibility claims of any kind nor do we provide recommendations on fire suppression systems. It is not recommended to position storage equipment directly in the path of high pressure gas discharge streams or loud fire sirens so as to minimize the forces and vibration adverse to system integrity.
