Support for configuring LLT over TCP
(Linux only)
VCS now provides the option of using LLT over the Transmission Control Protocol (TCP) layer for clusters using wide-area networks and routers. TCP makes LLT packets routable and thus able to span longer distances more economically.
Use LLT over TCP in the following scenarios:
When using CVM or FSS on AWS for improved IO Shipping performance
When hardware, such as blade servers, do not support LLT over Ethernet
Also, when you configure LLT over TCP layer for clusters using wide-area networks and routers, you can use the LLT_TCP_CONNS parameter to control the number of TCP connections that can be established between peer nodes.
The default value of this parameter is 8 connections. However, you can extend this value to maximum 64 connections.
