Oracle ZFS Storage Appliance Service Manual

ZS3-2 Controller Hardware Overview
■
Motherboard - The motherboard includes CPU modules, slots for 16 DIMMs, memory
control subsystems, and the service processor (SP) subsystem. The SP subsystem controls
the host power and monitors host system events (power and environmental). The SP
controller draws power from the host 3.3V standby supply rail, which is available whenever
the system is receiving AC input power, even when the system is turned off.
■
Power Distribution Board - The power distribution board distributes main 12V power
from the power supplies to the rest of the controller. It is directly connected to the connector
break out board and to the motherboard through a bus bar and ribbon cable. It also
supports a top cover interlock kill switch. The power supplies connect directly to the power
distribution board.
■
Storage Drive Backplane - The storage drive backplane includes the connectors for the
storage drives, as well as the interconnect for the I/O board, power and locator buttons, and
system/component status LEDs. The system has an 8-disk backplane. Each drive has an
LED indicator for Power/Activity, Fault, and Locate.
ZS3-2 Motherboard, Memory, and PCIe Cards - The ZS3-2 controller motherboard,
memory, and PCIe components are described in the following figure and legend.
Note - Field replaceable components (FRUs) are not customer-serviceable, and must be
replaced by trained Oracle service technicians.
