8.3 NVMe* Storage Support
Non-Volatile Memory Express (NVMe*) is an optimized, high-performance scalable storage interface
designed to address the needs of enterprise systems that use PCIe®-based solid-state storage. NVMe*
provides efficient access to non-volatile memory storage devices. The NVMe* technology allows Intel server
boards to take advantage of the levels of parallelism possible in modern SSDs.
8.3.1 PCIe* SlimSAS* Support
SlimSAS* is a next generation ultra-high-speed interconnect solution for server boards and storage devices.
They offer superior signal integrity performance over standard Mini-SAS HD connectors. The SlimSAS
connectors are compliant with T10/Serial attached SCSI (SAS-4) standard.
The server board includes eight x4 PCIe* SlimSAS* connectors. These connectors can be used to connect the
server board to NVMe* drives. PCIe* lanes from CPU 0 and CPU 1 are each routed to four PCIe* SlimSAS*
connectors. See the following figure. The CPU 0 PCIe* SlimSAS
* connectors are labeled “CPU0_PCIe*_PortA”
through “CPU0_PCIe*_PortD” on the server board. The CPU 1 PCIe* SlimSAS* connectors are labeled
“CPU1_PCIe*_PortA” through “CPU1_PCIe*_PortD” on the server b oard.
Figure 49. PCIe* SlimSAS* Connectors
The following table provides the PCIe* port routing information for the server board PCIe* SlimSAS
connectors.
