24 x 2.5-inch front drive bays (8SAS/SATA+16NVMe)
This section provides cable routing information for the server model with 24 x 2.5-inch front drive bays
(8SAS/SATA+16NVMe).
The server model is configured with one 8 x 2.5-inch SAS/SATA backplane (BP 1) and two 8 x 2.5-inch
AnyBay backplanes (BP 2 and BP 3). Below lists all supported configurations with these three front drive
backplanes.
Note: The AnyBay backplanes (BP 2 and BP3) are used as pure NVMe backplanes.
