Backplane Feature Set; Backplane Block Diagram - Intel H2000 Technical Product Specification

Hard Disk Drive Support
Each compute node in the system has dedicated Hot Swap Controller (HSC) to manage three
or four HDDs. There are totally four sets of independent Programmable System On Chip
(PSOC) on the backplane, to function as HSC respectively to four compute nodes.
The following sections describe the feature and connections between the backplane and
server board.
5.3.1

Backplane Feature set:


Common HSBP Microcontroller Cypress* PSoC 1 part

H2312xxJR/KR: 12x SAS/SATA 3.5" HDDs at 6Gb/s SAS/SATA or slower speeds,
divided into four groups of three hot swap hard drives. Each HDD group is associated
with one of the four compute nodes respectively in the 2U chassis.

H2216xx/JR/KR: 16x SAS/SATA 2.5" HDDs at 6Gb/s SAS/SATA or slower speeds,
divided into 4 groups of four hot swap hard drives. Each HDD group is associated with
one of the four compute nodes respectively in the 2U chassis.

One SGPIO SFF-8485 interface per compute node, total of four SGPIO on the
backplane.

Three SMB interfaces supported on the HSBP:
o SMBUS R1 - For chassis temp sensor and chassis FRU EEPROM
device.
o SMBUS R5 - Connectivity to up to two HSBP controllers and one shared
12V current monitoring device.
o SMBUS R7 - Connectivity to up to two common redundant power supply
(CRPS) module PMBus.

Integrated front panel control connectors

Status LED and Activity LED for each hard disk drive.

5V_AUX switcher regulator (from 12V and 12VSB) for HDD power and for compute
nodes.

Each grouping of HDD slots has switches for 5V and 12V power, only when
corresponding compute node is plugged in and operating will power be provided to the
HDDs.

3.3V switcher regulator (from 12V) to power microcontroller, SAS/SATA re-drivers on the
bridge board and various other components.

3.3V_AUX linear regulator (from 5V_AUX) for temp sensor, and chassis FRU EEPROM
located on the HSBP.

Four 80-pin bridge board connectors, one per compute node.

Four compute node main power connectors, one per compute node.

Four 2x9pin power cable connections and one 2x9pin power control cable connections.
These cables are routing to two power distribution boards (PDB).

Shared speaker for all compute nodes.
