Power Sources; Power Consumption - IBM XIV Gen3 Series Planning Manual

for safe operation and is compliant with IEC, EN, UL, CSA 60950-1 standards.
However, if leakage detection circuit breakers are required by local electrical
practice, the breakers must be sized for a leakage-current rating of 300 mA or
greater to reduce the risk of server outage caused by erroneous and spurious
tripping.

Power sources

Several ac power source configurations are available.
v Two 30 A, 200-240 V ac, three-phase receptacles, each connected to a different
power source
v Two 60 A, 200-240 V ac, three-phase receptacles, each connected to a different
power source
v Two 60 A, 200-240 V ac, single-phase receptacles, each connected to a different
power source.
The IBM XIV Storage System is protected by an uninterruptible power supply for
internal use. However, you can reduce the risk of a power outage by connecting
the system to an external uninterruptible power supply, a backup generator, or
both.
J1 is the primary feed. This allows for better data center power usage because the
ATS returns to J1 if there is power to that connector.
If the three-phase, 30A ATS for non-EMEA (feature code 9894) is installed and both
power feeds into the XIV system have voltages within the operational tolerance,
the power load is shared across both power feeds. If a power feed fails, the ATS
switches the full power load to the remaining feed.
To prepare the power cables, you must provide your IBM service representative
with the following information before the installation:
v The distance from the rack to the power receptacles.
v Whether overhead or under-floor power-cabling is to be used.

Power consumption

This information describes the power consumption for partial and full rack
configurations.
The following table lists the power consumption for each supported disk-drive
module (DDM) capacity with solid-state drives (SSDs). If no SSDs are present, the
power consumption is marginally less.
The power consumption for partial-rack configurations is the typical value and is
provided only for reference purposes. To support concurrent capacity upgrades,
the installation site must provide sufficient power capacity to support high
performance on a full rack configuration of 15 modules.
The high-performance measurements in the following tables were taken in an
environment with a room temperature of 25° C (77° F).
