and eHBA Tri-Mode Storage Adapters
PCIe (NVMe) Support
The following table shows how many NVMe drives or Broadcom PEX88000-series switches can directly attach to each
adapter. The 9600W-16e adapter, 9600-16e adapter, and 9600-8i8e adapter (external ports) do not support direct attach
to NVMe drives. The expected topology for these adapters is a typical JBOF scenario that uses a switch to connect the
NVMe drives.
NOTE
Connected NVMe drives must support end-to-end CRC (ECRC).

The adapter phys are grouped into two CSWs: CSW1[0:15] and CSW0[0:15]. Depending on the adapter, 8 or 16 of these
phys are used consecutively for the PCIe host interface and the remaining tri-mode phys are available for connection to
any supported SAS, SATA, or PCIe (NVMe) storage devices. The following tables indicate supported topologies. Typical
backplane designs naturally align to these topology rules, but you must take care not to design anything atypical that
might interfere with the adapter’s operation.
