Hot Swap Backplane Support; Figure 34. Backplane Installation - Intel R1000WF Technical Product Specification

Intel® Server System R1000WF Product Family Technical Product Specification
Note: The drive activity LED is driven by signals coming from the drive itself. Drive vendors may choose to
operate the activity LED different from what is described in the table above. Should the activity LED on a
given drive type behave differently than what is described, customers should reference the drive vendor
specifications for the specific drive model to determine the expected drive activity LED operation.

Hot Swap Backplane Support

The 1U system has support for two backplane options.
For 2.5" drives, available backplane options include:
• 8 x 2.5" drive combo backplane with support for SAS/SATA/NVMe
4 x 3.5" drive backplane with support for SAS/SATA
•
All available backplane options mount directly to the back of the drive bay as shown in Figure 34.
Backplanes include the following features:
12 Gb SAS and 6 Gb SAS/SATA or slower support
•
Drive interface connectors
•
o 29-pin SFF-8680 – SATA/SAS only
o 68-pin SFF-8639 – SATA/SAS/NVMe – NVMe compatible backplanes only
• Hot swap drive support
Cable connectors
•
o SFF-8643 Mini-SAS HD – 2.5" and 3.5" backplanes – 12 Gb SAS capable
o OCuLink PCIe* interface – NVMe compatible backplanes only
o 1x5-pin connector – I2C interface for device status communication to the BMC over slave
SMBus*
o 2x2-pin connector – power
SGPIO SFF-8485 interface embedded within the sideband of the mini-SAS HD connectors
