One 8 x SAS/SATA and one 8 x NVMe backplanes
This section provides cable routing information for the server model with one 8 x 2.5-inch SAS/SATA and one
8 x 2.5-inch NVMe front backplanes.
To connect power cables for the front backplane(s), refer to
“Backplanes: server models with 2.5-inch front
drive bays” on page 312
.
To connect signal cables for the front backplane(s), refer to the following cable routing scenarios depending
on your server configuration.
• “8i RAID/HBA adapter” on page 355
• “Riser 5 + OCP interposer cards + 8i RAID/HBA adapter” on page 357
• “Riser 3/4/5 + 8i RAID/HBA adapter + Retimer card” on page 359
8i RAID/HBA adapter
The following shows the cable connections for the front (8 x 2.5-inch SAS/SATA + 8 x 2.5-inch NVMe)
configuration with one 8i RAID/HBA adapter.
To connect the processor interconnection cable when two processors are installed, see
“Processor
interconnection cable routing” on page 311.
