1-3 Chassis Features
The S-R2K22BP chassis houses four separate computing nodes, each
containing its own motherboard.
System Power
The system features dual redundant 2200 W power supplies consisting of two
hot-plug power modules. They have 80 Plus certification at Titanium Level (96%)
high-efficiency. The system will continue to operate if one module fails or is replaced.
Drives
The chassis includes twenty-four hot-swap 2.5" storage drives, so each node
supports six drives. Drive types vary with model, as noted on page 1-1.
PCI Expansion Slots
The system allows eight low profile, externally accessable PCI-E cards, two in
each node.
Front Control Panels
Each node has a control panel on the front of the chassis that provides system
monitoring and power control. Status LEDs indicate system power, drive activity,
network activity, UID, and overheat and fan failure.
Cooling System
The chassis uses four system fans powered from the motherboards through the
backplane. The two fans on each side are controlled by the two motherboards on
that side, so that when one of the motherboard nodes is removed, the second
motherboard will continue to control both fans. Fan speed can be determined by
system temperature through IPMI.
Each node uses an air shroud to channel air where needed. Each power supply
module also includes a cooling fan.
