Maximum performance with up to 1.3 million input/output operations per second (IOPS) to support larger server virtualization deployments & scalable cloud initiatives, and performance to match new multicore processors, SSDs/flash storage, and faster server host bus architectures. Independent function, transmit & receive buffers, an on-chip CPU, DMA channels, and a firmware image for each port enable complete port-level isolation, prevent errors & firmware crashes from propagating across all ports, and provide predictable & scalable performance across all ports.
