12 IBM BladeCenter PS703 and PS704 Technical Overview and Introduction1.3.2 Number of PS703 and PS704 blades in a chassisThe number of POWER7 processor-based blades that can be installed in a BladeCenterchassis depends on several factors: BladeCenter chassis type Number of power supplies installed Power supply voltage option (BladeCenter S only) BladeCenter power domain configurationTable 1-3 shows the maximum number of PS703 and PS704 blades running in a maximumconfiguration (memory, disk, expansion cards) for each supported BladeCenter chassis thatcan be installed with fully redundant power and without performance reduction. IBM bladesthat are based on processor types other than POWER7 might reduce these numbers.Table 1-3 PS703 and PS704 blades per chassis typeWhen mixing blades of different processor types in the same BladeCenter, the BladeCenterPower Configurator tool helps determine whether the combination desired is valid. It isexpected that this tool will be updated to include the PS703 and PS704 blade configurations.For more information about this update, see the following web page:http://www.ibm.com/systems/bladecenter/powerconfig1.4 Operating environmentIn this section, we list the operating environment specifications for the PS703 and PS704blade servers and BladeCenter H and S.PS703 and PS704 Operating temperature– 10°C - 35°C (50°F - 95°F) at 0 - 914 meters altitude (0 - 3000 feet)– 10°C - 32°C (50°F - 90°F) at 914 - 2133 meters altitude (3000 - 7000 feet) Relative Humidity 8% - 80% Maximum Altitude 2133 meters (7000 ft.)Tip: As shown in Table 1-3, there is no restriction to the number of POWER7 blade serversthat you can install in a BladeCenter chassis other than the number of power suppliesinstalled in the chassis.ServerBladeCenter H BladeCenter HT BladeCenter S14 Slots Total 12 Slots Total 6 Slots Total110VAC 208VAC2 PS 4 PS 2 PS 4 PS 2 PS 4 PS 2 PS 4 PSPS703 7 14 6 12 2 6 2 6PS704 3 7 3 6 1 3 1 3
