Supported Operating Systems for NPAR
The Cavium 8400/3400 Series 10GbE Adapters support NPAR on the following
operating systems:
Windows Server 2008 family
Windows Server 2012 family
Windows Server 2016 family
Linux 64-bit, RHEL 5.5 and later, SLES 11 SP1 and later
VMware ESXi 5.0, 5.1, 5.5, 6.0, and 6.5
Configuring for NPAR
When NPAR is enabled on an adapter, by default, no offloads are enabled on any
physical function (PF) or virtual NIC (vNIC). The user must explicitly configure
storage offloads on a PF to use FCoE and iSCSI offload on an adapter.
Configuration Parameters
This section describes the NPAR configuration parameters, including:
NOTE
32-bit Linux operating systems have a limited amount of memory space
available for Kernel data structures. Therefore, you should use only 64-bit
Linux to configure NPAR.
NOTE
In NPAR mode, SR-IOV cannot be enabled on any PF (vNIC) on which
storage offload (FCoE or iSCSI) is configured. This restriction does not apply
to adapters in single function (SF) mode.
NOTE
In NPAR mode, you should avoid teaming or bonding partitions on the same
physical media. Such configuration still results in a single point of failure that
defeats the purpose of ports teaming or ports bonding.
