Pensando Distributed Services Platform (DSC) adapters have 2 high speed ethernet controllers (for example vmnic6 and vmnic7 ) and one management controller (for example vmnic8 ): :~] esxcfg-nics -l vmnic6 0000:39:00.0 ionic_en_unstable Up 25000Mbps Full 00:ae:cd:09:c9:48 1500 Pensando Systems DSC-25 10/25G 2-port 4G RAM 8G eMMC G1 Services Card, Ethernet Controller vmnic7 0000:3a:00.0 ionic_en_unstable Up 25000Mbps Full 00:ae:cd:09:c9:49 1500 Pensando Systems DSC-25 10/25G 2-port 4G RAM 8G eMMC G1 Services Card, Ethernet Controller :~] esxcfg-nics -lS vmnic8 0000:3b:00.0 ionic_en_unstable Up 1000Mbps Full 00:ae:cd:09:c9:4a 1500 Pensando Systems DSC-25 10/25G 2-port 4G RAM 8G eMMC G1 Services Card, Management Controller The high-speed ethernet controllers vmnic6 and vmnic7 register first and operate with RSS set to 16 receive queues. :~] localcli --plugin-dir /usr/lib/vmware/esxcli/int networkinternal nic privstats get -n vmnic6…Num of RSS-Q=16, ntxq_descs=2048, nrxq_descs=1024, log_level=3, vlan_tx_insert=1, vlan_rx_strip=1, geneve_offload=1 } However, in rare cases, if the management controller vmnic8 registers first with the vSphere Distributed Switch, the high-speed ethernet controllers vmnic6 or vmnic7 uplink might end up operating with RSS set to 1 receive queue. :~] localcli --plugin-dir /usr/lib/vmware/esxcli/int networkinternal nic privstats get -n vmnic6…Num of RSS-Q=1, ntxq_descs=2048, nrxq_descs=1024, log_level=3, vlan_tx_insert=1, vlan_rx_strip=1, geneve_offload=1 } As a result, you might see slower performance in native mode.
Reload the ionic_en driver on ESXi by using the following commands: :~] esxcfg-module -u ionic_en :~] esxcfg-module ionic_en :~] localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal bind .
