We're a MSP running many public and private VMware ESXi workloads. We mostly use Dell hardware but HP and Supermicro is also employed. We run a mixture of network adapters of Mellanox, Intel, Broadcom and Qlogic chipsets (ignoring vendor implementations) / driver - combos. Interconnects are 1g copper, 10g sfp+ mm/dac and remote is typically Juniper/Cisco/Dell.
We have noticed over the course of several years, using combined experience of several networking/vmware collegaes to conclude that Qlogic/Broadcom 1/10g adapters experience the most outage (side-noting: in almost all cases fw/driver up/down-grades fixed the issue). Intel seems to be the most prefered option among the people I've met on this topic, as these adapters don't seem to be running into issues in the first-place, or at a less greater interval than their competitors.
How has your experience been?
