SPE3 and DAE3P tec hnical specificationsTechnical specif ications include storage-system power requirements,size, drive, inte rface, and environment information.

Power requirements

The input current, power (VA), and dissipation per enclosure listedin this document are based on the maximum capability of the powersupplies and cooling system to provide internal regulated power. Thesevalues represent either:

the values for a single power supply line cord, or

the 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 storage processorresults in the remaining power supply supporting the full load.You must use a rackmount cabinet or rack with appropriate powerdistribution, and have main branch AC distribution that can handlethese values for each SPE3 and DAE3P in the cabinet.

The power and current ratings below are maximum ratings for a model numberfamily, and are intended to guide the sizing of power distribution componentsat the cabinet/rack level. These values may not be appropriate to estimatetypical power consumption, as model configurations and drive types vary.

DAE3P drive type

The DAE3P uses 3.5 in (8.75 cm) by 1.0 in (2.54 cm) disk drives.Fibre Channel drives are 12-volt, and support the Fibre Channelinterface. SATA drives are 12- and 5-volt and support theSATA 3 Gb interface; a paddle card on the drive converts theassembly to 12-volt Fibre Channel operation. Each drive slotprovides an average maximum of 16 W drive module power.The EMC Storage Systems CX-Series Disk and FLARE OE Matrixonthe EMC Powerlink website ( http://Powerlink.EMC.com ) lists thesupported drives.

SP optica l cabling to Fibre Channel switch or serverOptical cables connect the small form-factor pluggable (SFP) moduleson the storage processors (SPs) to the external Fibre Channelenvironment.

SP network cablingStorage systems with iSCSI data ports use standard Ethernet LANcables from the LAN (iSCSI data) ports (RJ45 connectors) on each SPto the external network environment. For distances up to 100 meters,Category 5E cables are the commonly used gigabit Ethernet standard;the system also supports CAT 5 and CAT 6 cables. EMC recommendsCAT 6 LAN cables whenever possible.

SP-to-DAE3P copper cabling

The cable connectors are either a shielded SFP (small form-factorpluggable) module direct attach or an HSSDC2 (high speed serial dataconnector), as detailed below:

SP connector Shielded, 150 differential, shield-bonded to SFPplug connector shell (360 ), SFF-8470 150 specification for SFPtransceiver.

DAE3P connector Shielded, 150 differential, shield-bonded toplug connector shell (360 ) FC-PI-2 standard, revision 13 or higherfor HSSDC2.

The expansion port interface to the SPE is copper cable. The followingcopper cables are available:

SPS battery information

Battery tests

Test Description

Internal test Within 60 minutes after powerup and periodically thereafter, the SPS performs a lig ht test on the batteries. This test lasts less than 2 seconds.It does not ve rify battery capacity but does check connectivity and functionality. This test is transparent to other components in the storage

system. If an actual power failure occurs during the test, the test is terminated and the unit goes into on-battery mode.

Full test At each storage-system startup, the system software initiates a fullpower test. During the test, the system disables write cache and allows the SPS to stay on for its entire 90-second period. The system initiates a full test when the SPS is online and fully charged. If the batteries are charging at test time, the system defers the test until the next programmed time.

Battery self-discharge times

When you store an SPS, the battery charge level naturally decreasesover time. This is characteristic of all rechargable batteries. The rate ofself-discharge depends on temperature. Lower storage temperaturesare desirable since the self-discharge rate is lower. The following graphshows how the remaining charge decreases over time at differenttemperatures.

Figure 1 Typical SPS self-discharge levels at different storage temperatures

IMPORTANT If you are storing an SPS, do not store it longer than 6 monthsor at a temperature exceeding 30 C without recharging it. When you retrievean SPS unit from storage, you should charge it by connecting it to AC power,with its power switch in the on position, for at least 12 hours before putting itinto service or returning it to storage.

SPE3, DAE3P, and S PS operating limitsThe ambient tempe rature specification is measured at the front bezelinlet. The site mu st have air conditioning of the correct size andplacement to main tain the specified ambient temperature range andoffset the heat dissipation listed below.


Ambient temperature 10C to 40C (50F to 104F)Temperature gradient 10C/hr (18F/hr)

Relative humidity 20% to 80% nonc ondensing

Elevation 2438 m (8,000 ft) at 40C 3077 m (10,000 ft) at 37C

IMPORTANT For systems mounted in a cabinet, the operating limitslisted above must not be exceeded inside the closed cabinet. Equipmentmounted dir ectly above or below an SPE3 storage system must not restrictthe front-t o-rear airflow of the storage system. The cooling airflow throughthe storag e system is approximately 64 cubic feet per minute (cfm). Cabinetdoors must not impede the front-to-rear airflow. The cabinet must exhaustair at a rat e that is equal to or greater than the sum of the exhaust rates of allthe equipment mounted in the cabinet. For example, in a cabinet containingone SPE3 (64 cfm) and six DAE3Ps (55 cfm), the cabinet must exhaust at least64+6x55 cfm, which equals 394 cfm.

Environmental recovery

If the system exceeds the maximum ambient temperature by

approximately 10 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 to



12/13

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