CX4-960 Storage System
Technical Specifications and Operating Limits
This document lists the technical specifications, operating limits, and shipping and storage requirements for your storage system. The storage system consists of a storage processor enclosure (SPE), one or more disk-array enclosures (DAEs), and a standby power supply (SPS). For descriptions of these components, refer to the CX4-960 Storage System Hardware and Operational Overview. Some documents refer to the DAE as the DAE3P.
Major topics are:

SPE and DAE technical specifications Technical specifications include storage-system power requirements, size, drive, interface, and environment information.
Power requirements 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:
the 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).
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 SPE and DAE in the cabinet.

Notes: Weights do not include mounting rails. Allow 2.3- 4.5 kg (5-10 lb) for a rail set. Platform-specific power ratings are in the technical specifications document for the product on the product’s support website, and include DC power ratings where appropriate. A fully configured DAE includes 15 disk drives that typically weigh 1.0 kg to 1.1 kg (2.25 to 2.4 lb) each. The weights listed in this table do not describe enclosures with Enterprise Flash Drives (solid state disk drives with Flash memory, called Flash or SSD drives). These SSD drive modules weigh 20.8 ounces (1.3 lb) each.
DAE drive type Fibre Channel drives are 12-volt, and support the Fibre Channel interface. SATA drives are 12- and 5-volt and support the SATA 3 Gb interface; a paddle card on the drive converts the assembly to 12-volt Fibre Channel operation. Enterprise flash drives (solid state disk drives with flash memory, or SSD drives) are 12-volt, and support the Fibre Channel interface. The EMC CX4 Series Storage Systems Disk and FLARE OE Matrix on the EMC Powerlink website (http://Powerlink.EMC.com) lists the supported drives.

SP optical cabling to a switch or server Optical cables connect the small form-factor pluggable (SFP) modules on the storage processors (SPs) to the external Fibre Channel or 10 Gb Ethernet environment. EMC strongly recommends the use of OM3 50 µm cables for all optical connections. Table 4 lists the optical cables that are available for your storage system. Table 4

The maximum length for either the 62.5 µm or 50 µm cable (noted in the table above) includes two connections or splices between source and destination.
!
CAUTION EMC does not recommend mixing 62.5 μm and 50 μm optical cables in the same link. In certain situations you can add a 50 μm adapter cable to the end of an already installed 62.5 μm cable plant. Contact your service representative for details.

SP twinaxial cabling for 10 Gigabit Ethernet environments Active twinaxial copper cables include small form factor pluggable (SFP) modules at either end. They connect Fibre Channel over Ethernet (FCoE) modules to FCoE switches, or 10 GbE/iSCSI modules to an external iSCSI environment. The twinaxial cables are shielded, quad-construction style, 100Ω differential; the SFP connectors comply with SFF-8431 and SFF-8472 standards. Transmit and receive ends include active components to facilitate 10 GbE transmission. EMC offers various lengths from 1 meter to 15 meters; wire gauges range from 24 to 30 with cable length.

SPE, DAE, and SPS operating limits The ambient temperature specification is measured at the front bezel inlet. The site must have air conditioning of the correct size and placement to maintain the specified ambient temperature range and offset the heat dissipation listed below. Requirement
Description
Ambient temperature
10°C to 40°C (50°F to 104°F)
Temperature gradient
10°C/hr (18°F/hr)
Relative humidity
20% to 80% noncondensing
Elevation
2286 m (7,500 ft) at 40°C 3047 m (10,000 ft) at 37°C
IMPORTANT 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 SPE must not restrict the front-to-rear airflow of the storage system. The cooling airflow through the storage system is approximately 130 cubic feet per minute (cfm) above 30°C (86°F). 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. For example, in a cabinet containing one SPE2 (130 cfm) and six DAEs (55 cfm), the cabinet must exhaust at least 130+6x55 cfm, which equals 460 cfm.
Environmental recovery If the system exceeds the maximum ambient temperature by approximately 10°C (18°F), the SPs begin an orderly shutdown that saves cached data, and then shut themselves down. Link control cards (LCCs) in each DAE3P power down their disks but remain powered on. If the storage system detects that the temperature has dropped to

an acceptable level, it restores power to the SPs and the LCCs restore power to their disk drives.
