Mellanox Technologies, Ltd. has announced the general availability of Mellanox VMA 5.0 with enhanced TCP acceleration support, providing a unified messaging acceleration platform for networking communications methods such as TCP, Multicast and UDP unicast.
Mellanox says its VMA 5.0 delivers sustainable latency under loads of over 2.5 million packets per second and dramatically improves UDP latency to under 2.0 microseconds and transparent sockets TCP latency to under 2.5 microseconds.
VMA is a dynamically linked user-space Linux library for accelerating messaging and streaming traffic. Applications that utilize standard BSD sockets use the library to offload network processing from a server’s CPU, with no application changes required. The application traffic is passed directly to the Mellanox ConnectX-2 10GigE or 40Gb/s InfiniBand adapter from the application user space, bypassing the kernel and IP stack and thus minimizing context switches, buffer copies and interruptions resulting.
