Chapter III. Virtual Function Network (vNIC)
Chelsio T5/T4 Unified Wire For Linux Page 59
1. Introduction
The ever increasing network infrastructure of IT enterprises has lead to a phenomenal increase
in maintenance and operational costs. IT managers are forced to acquire more physical servers
and other data center resources to satisfy storage and network demands. To solve the Network
and I/O overhead, users are opting for server virtualization which consolidates I/O workloads
onto lesser physical servers thus resulting in efficient, dynamic and economical data center
environments. Other benefits of Virtualization include improved disaster recovery, server
portability, cloud computing, Virtual Desktop Infrastructure (VDI), etc.
Chelsio’s T5 and T4 Unified Wire family of Adapters deliver increased bandwidth, lower latency
and lower power with virtualization features to maximize cloud scaling and utilization. The
adapters support SFP+ and 10BASE-T media. The adapters also provide full support for PCI-
SIG SR-IOV to improve I/O performance on a virtualized system. User can configure up to 128
Virtual and 8 Physical functions (with 4 PFs as SR-IOV capable) along with 336 virtual MAC
addresses.
