CX4-120 Storage System Technical Specifications and Operating Limits

CX4-120Storage SystemTechnical Specifications andOperating LimitsJune24,2008This document lists the technical specifications,operating limits,andshipping and storage requirements for your storage system.The storage system consists of a storage processor enclosure(SPE),one or moredisk-array enclosures(DAEs),and a standby power supply(SPS).For descriptions of these components,refer to the CX4-120Storage System Hardware and Operational Overview.Some documents refer to the DAE as the DAE3P.Major topics are:SPE and DAE technical specifications (2)SPS technical specifications (8)SPE,DAE,and SPS operating limits (9)1SPE and DAE technical specificationsTechnical specifications include storage-system power requirements,size,drive,interface,and environment information.Power requirementsThe input current,power(VA),and dissipation per enclosure listedin this document are based on measurements of fully configuredenclosures under worst-case operating e the operatingmaximum values to plan the configuration of your storage system.These values represent either:the values for a single power supply line cord,orthe sum of the values shared by the line cords of the combinedpower supplies in the same enclosure,with the division between theline cords and supplies at the current sharing ratio(approximately50%each).A failure of one of the combined power supplies per enclosure resultsin the remaining power supply supporting the full load.You must usea rackmount cabinet or rack with appropriate power distribution,andhave main branch AC distribution that can handle these values foreach SPE and DAE in the cabinet.2Technical Specifications and Operating LimitsTable1CX4-120AC power specificationsRequirement DescriptionDevice electrical rating100to240V

Operating LimitsSPE,DAE,and SPS operating limitsThe ambient temperature specification is measured at the front bezelinlet.The site must have air conditioning of the correct size andplacement to maintain the specified ambient temperature range andoffset the heat dissipation listed below.Requirement DescriptionAmbient temperature10°C to40°C(50°F to104°F)Temperature gradient10°C/hr(18°F/hr)Relative humidity20%to80%noncondensingElevation2286m(7,500ft)at40°C3047m(10,000ft)at37°CIMPORTANT For systems mounted in a cabinet,the operating limits listedabove must not be exceeded inside the closed cabinet.Equipment mounteddirectly above or below an SPE must not restrict the front-to-rear airflowof the storage system.The cooling airflow through the storage system isapproximately64cubic feet per minute(cfm).Cabinet doors must not impedethe front-to-rear airflow.The cabinet must exhaust air at a rate that is equal toor greater than the sum of the exhaust rates of all the equipment mounted in thecabinet.For example,in a cabinet containing one SPE3(64cfm)and six DAEs(55cfm),the cabinet must exhaust at least64+6x55cfm,which equals394cfm.Environmental recoveryIf the system exceeds the maximum ambient temperature byapproximately10°C(18°F),the SPs begin an orderly shutdown thatsaves cached data,and then shut themselves down.Link control cards(LCCs)in each DAE3P power down their disks but remain poweredon.If the storage system detects that the temperature has dropped toTechnical Specifications and Operating Limits9an acceptable level,it restores power to the SPs and the LCCs restorepower to their disk drives.Shipping and storage requirementsRequirement DescriptionAmbient temperature-40°C to65°C(-40°F to149°F)Temperature
