Power And Cooling; Power Configurations; Ac Power Source Options; Power Redundancy Options - Oracle StorageTek SL3000 System Assurance Manual

All power supplies and power distribution units (PDUs) reside in the Base module
and DEM. When selecting a power configuration, consider any power redundancy
requirements along with the features and number of drives that will be supported in
the library.

Power Configurations
The power configuration depends on the power source and the power redundancy.

AC Power Source Options

Each PDU installed in the library requires a separate AC power source. There can be a
maximum of four PDUs in the library depending on the configuration selected (two in
the Base module and two in the DEM). There are two AC power source options. Both
are single phase:
120 VAC, 50/60 Hz, at 20 amps (range: 100–127 VAC, 47–63 Hz, 16 amps)
■
–
240 VAC, 50/60 Hz, at 30 amps (range: 200–240 VAC, 47–63 Hz, 24 amps)
■
–

Power Redundancy Options

There are three power configurations that offer various levels of power redundancy.

N+1 power configuration (standard)

Offers DC power redundancy only
■
Consists of one PDU (per Base module or DEM), with one extra drive DC supply
■
and one extra robotics DC supply
Provides N+1 DC power supply redundancy
■
Limited support for T9840 and T10000 drives; no redundant robotics support
Supports all drive types and redundant robotics
