SSUG::Digital: 017 – Multiple Connections over TCP (MCOT)

18th January 2022 @ 16:00 - 17:00 GMT

Starting with IBM Spectrum Scale 5.1.1, Multiple Connections Over TCP (MCOT) is enabled by default which enhances the IBM Spectrum Scale communication subsystem to establish multiple TCP connections for communication between each pair of Spectrum Scale daemons (mmfsd). Using more connections may improve performance and resiliency, particularly for some bonded configurations which can use more than one physical interface per node with multiple TCP connections. Depending on factors like network speed and number of nodes, the value of the new maxTcpConnsPerNodeConn parameter may need to be adjusted up or down.
