H11SSL Motherboard Series User's Manual
L-SAS Ports (L-SAS0~L-SAS7), H11SSL-NC & H11SSL-C Only
The motherboard supports eight (8) SAS ports on two onboard connectors, L-SAS0~L-SAS3
and L-SAS4~L-SAS7. Connect hard drives to these SAS ports using a MiniSAS to 4 breakout
cable, one for each connector that supports up to four drives each.
NVM Express
Connections Two NVM Express ports are located on the serverboard (one for each processor).
These ports provide high-speed, low-latency PCI-Exp. 3.0 x4 connections directly from the CPU
to NVMe Solid State (SSD) drives. This greatly increases SSD data-throughput performance
and significantly reduces PCI-E latency by simplifying driver/software requirements resulted
from direct PCI-E interface from the CPU to the NVMe SSD drives.
