9540-2M2 Boot Adapter
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
Storage Interface Features
The adapter’s SerDes technology enables maximum flexibility by supporting NVMe or SATA M.2 drives for operating
system boot applications. The adapter detects the drive type and negotiates between speeds and protocols to
automatically recognize and function with NVMe or SATA M.2 drives.
•
PCIe (NVMe) interface features:
–
x1, x2, or x4 NVMe drive support
–
Data transfer at 16GT/s, 8GT/s, 5GT/s, and 2.5GT/s
•
SATA interface features:
–
SATA data transfer rates of 6Gb/s and 3Gb/s
Adapter Security
The adapter hardware secure boot security feature protects your system from malicious activity.
Hardware secure boot permits only authenticated firmware to execute on the adapter. The adapter boots from an internal
boot ROM, which establishes the initial root of trust (RoT). Hardware secure boot authenticates and builds a chain of trust
(CoT) with succeeding firmware images by using the RoT, meaning only authorized firmware executes on the adapter.
