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
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.
