2.3 Functional Descriptions
2.3.1 PCIe Host Interface
The ThinkSystem RAID adapters have eight PCIe PHYs, which provide host-side maximum transmission and reception
rates of 64 Gb/s (8 Gb/s per PHY). The RAID adapters use a packet-based communication protocol to communicate over
the serial interconnect. Other PCIe host interface features include:

Eight PCIe host lane interface

Power management
—
Supports the PCI Bus Power Management Interface Specification , Revision 1.2
—
Supports Active State Power Management 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 8GT/s, 5GT/s, and 2.5GT/s in each direction

Eight-lane aggregate bandwidth of up to 8 GB/s (8000 MB/s)

Support of x8, x4, x2, and x1 link widths
2.3.2 SAS/SATA LED Operation
LED signals indicate an error condition or drive activity. SAS/SATA LED management is supported by SGPIO. The
functionality is described in the SFF-8485 specification.
See Section 2.5.1, Board Layout, LEDs, Jumpers, and Connectors for the descriptions and locations of the LEDs on your
adapter.
Refer to the Lenovo ThinkSystem Storage Adapter Software User Guide for more information about actions you can take
related to the LEDs.
