SGPIO Functionality

Backplanes include support for a SFF-8485 compliant SGPIO interface used to activate the status LED. This
interface is also monitored by the microcontroller for generating FAULT, IDENTIFY, and REBUILD registers
that in turn are monitored by the server board BMC for generating corresponding SEL events.
5.2.2 I C Functionality
2
The microcontroller has a master/slave I
an IPMB compliant device. The BMC generates SEL events by monitoring registers on the HSBP
microcontroller for DRIVE PRESENCE, FAULT, and RAID REBUILD in progress.

8 x 2.5" Drive SATA/SAS/NVMe* Combo Backplane

This section applies to the 8 x 2.5" drive SAS/SATA/NVMe combo backplane (iPC – F1U8X253PHS).
All system SKUs capable of supporting 2.5" drives include an eight drive backplane capable of supporting 12
Gb/sec SAS, 6 Gb/sec SATA drives, and PCIe NVMe drives.
The 8x2.5" drive combo backplane has support for different drive configurations including SAS or SATA only,
NVMe only, or a combination of both SAS and NVMe. Mixing of SATA and SAS devices within a common hot
swap backplane is not supported. Hard disk drives (HDDs) and solid state srives (SSDs) can be supported
within a common backplane.
The front side of the backplane includes eight 68-pin SFF-8639 drive interface connectors, each capable of
supporting SAS, SATA, or NVMe drives. The connectors are numbered 0 through 7.

The backplane and backplane management features can support drives installed in any order when
populating mixed SATA/NVMe or SAS/NVMe drive configurations. However, when mixing NVMe and
SATA/SAS within a common backplane, Intel recommends drive types be populated together and not in an
intermixed order. In addition, drive population rules must be followed and drive support limitations exist
when the optional Intel® VROC upgrade key is installed to the server board providing support for NVMe RAID
and NVMe management features (see Section 6.4.4).
The backside of the backplane includes two multi-port mini-SAS HD connectors labeled SAS/SATA_0-3 and
SAS/SATA_4-7, and eight PCIe OCuLink connectors, each labeled PCIe SSD#, where # = 0 -7, one connector
for each installed NVMe drive.
