PCIe Host Interface

The adapter's PCIe 4.0 host interface provides maximum transmission and reception rates of up to 128 GT/s (16GB/s per
lane). The tri-mode controller uses a packet-based communication protocol to communicate over the serial interconnect.
Other PCIe host interface features include the following:
•
Eight-lane PCIe host interface
•
PCIe Hot Plug
•
Power management
–
Supports the PCI Bus Power Management Interface Specification Revision 1.2
–
Supports Active State Power Management, including the L0 states, by placing links in a power-saving mode during
times of no link activity
•
Error handling
•
High bandwidth per pin with low overhead and low latency
•
Lane reversal and polarity inversion
•
Single-phy (one-lane) link transfer rate of 16 GT/s, 8 GT/s, 5 GT/s, and 2.5 GT/s in each direction
•
Eight-lane aggregate bandwidth of up to 16GB/s (16,000 MB/s)
•
Support of x8, x4, x2, and x1 link widths

LED Management

The internal adapters offer LED management support for SAS/SATA backplanes and (PCIe) NVMe backplanes. External
connect adapters offer enclosure LED management support for enclosure implementations through SES. See
Management for more information.

Tri-Mode Storage Interface Features

The adapter's storage interface supports concurrent operation with SAS, SATA, and PCIe (NVMe) devices to provide a
fully functional solution for any storage environment.
•
PCIe (NVMe) interface features:
–
Up to sixteen x1, eight x2, or four x4 NVMe direct-attach drive support
–
Data transfer at 16 GT/s, 8 GT/s, 5 GT/s, and 2.5 GT/s
–
Independent resets and configuration
–
Common reference clock and separate reference clock independent SSC (SRIS) support
