= InfiniBand resources for improving InfiniBand Gentoo wiki -article = If anyone has urge/need to improve the article, I list some resources here for me as a reminder and for others to use.

What is this InfiniBand anyway? And how it compares to Ethernet?
”''InfiniBand is a high-speed serial computer bus, intended for both internal and external connections. It is the result of merging two competing designs, Future I/O, developed by Compaq, IBM, and Hewlett-Packard, with Next Generation I/O (ngio), developed by Intel, Microsoft, and Sun Microsystems. From the Compaq side, the roots were derived from Tandem's ServerNet. For a short time before the group came up with a new name, InfiniBand was called System I/O.''

''Ethernet: A computer network cabling system designed by Xerox in the late 1970s. Originally transmission rates were 3 Megabits per second (Mb/s) over thick coaxial cable. Media today include fiber, twisted-pair (copper), and several coaxial cable types. Rates are upto 10 Gigabits per second or 10,000 Mb/s.''”

InfiniBand stops working after suspend/hibernate
”When running applications that use ND or libibumad (such as OpenSM) the system might get to an unstable state when trying to shutdown/restart/hibernate it.” Solution would be to shut down all programs using libibumad. To be sure it would be best to even unload all ib_* modules althogether. This is a problem at least on Mellanox branded HCAs.

Hibernate and Sleep are not functional when user-space is using its resources.
Mellanox HCA issue. No offical answer. Solution above should work.
