Known Affected Releases


Description (partial)

Customers will see decreased storage performance, as compared to standard FNIC or earlier (6.5) ESXi releases. Specifically, kAvg under ESXtop will be high (greater than 1), and there will be a high number of "Split commands" or "PAE Commands". 

(On a well-tuned, healthy system, we would expect the kAvg and split commands be zero.)

ESXi 6.7 (U1, U2 as well).
Cisco VIC with NFNIC driver (4.0.0.X-49)
Typically seen under heavy load conditions only, or with very fast (all flash) arrays
