5. 16 drive bays, where 8 are AnyBay
In 16-drive configurations where eight of the bays are AnyBay drive bays, you can select either one 16-port
adapter or two 8-port adapters for SAS/SATA connectivity. In addition, the NVMe connectivity depends on
whether you have two or four processors installed: for two-processor systems, two NVMe Switch Adapters
are required; for four-processor systems, the onboard NVMe ports is used for four of the AnyBay drive
bays and an NVMe Switch Adapter is needed for the other four AnyBay drive bays. The configurations are
shown in the following figure.
