Adapter Features & Their Importance
9 Emulex Confidential
Adapter / Controller Features
Characteristic Values Importance Number of network ports 1 port or
2 ports Having 2 ports enables failover architecture or active-active config
Host Interface PCI-X PCIe v1.0 PCIe v2.0
PCIe v2.0 supports 1-32 lanes of 5GHz per lane. Essentially removing host interface as the bottleneck
Interrupt MSI MSI-X
MSI-X enables interrupt vector assignments. Each CPU gets its own vector. Works well with RSS.
Internal & External Memory Varies significantly from vendor to vendor
Stateful offloads use the internal and external memory for maintaining connection state.
Throughput, CPU Utilization, Latency
Varies significantly from vendor to vendor
The adapter should support wire-speed performance The latency and CPU Utilization must be low
10 Emulex Confidential
Adapter / Controller Features
Characteristic Values Importance Offloads Stateless offloads Almost all adapter support
stateless offloads Chimney (Partial Offload) Full TCP Offload
Intel is an exception in supporting Full TCP offload. TOE provides acceleration for networking and NAS traffic
Partial iSCSI / FCoE offload; Full iSCSI / FCoE offload
Full offload is required for high throughput and low latency
RDMA Low Latency needs to be maintained. Latency measured from the time a bit leaves the wire to when it reaches application buffer
11 Emulex Confidential
