Two 8 x SAS/SATA and one 8 x NVMe (Gen 4) backplanes
This section provides cable routing information for the server model with two 8 x 2.5-inch SAS/SATA and one
8 x 2.5-inch NVMe (Gen 4) 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 421
• “16i RAID/HBA adapter” on page 423
• “CFF 16i RAID/HBA adapter” on page 425
8i RAID/HBA adapter
The following shows the cable connections for the front (16 x 2.5-inch SAS/SATA + 8 x 2.5-inch Gen 4
NVMe) configuration with two 8i RAID/HBA adapters.
