vSphere Distributed Switch MTU mismatch

Based on event
MtuMismatchEvent

Error

Manual

A larger MTU (maximum transmission unit) bring greater efficiency because each packet carries more user data while protocol overheads; the resulting higher efficiency means a slight improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data. However, this gain is not without some downside. Large packets can occupy a slow link for some time, causing greater delays to following packets and increasing lag and minimum latency.

ResourceViolatedEvent

Error

Manual

Storage ATS support failure

Based on event
esx.problem.vmfs.ats.support.lost

Error

Manual

In a shared storage environment, when multiple hosts access the same VMFS datastore, specific locking mechanisms are used. These locking mechanism prevent multiple hosts from concurrently writing to the metadata and ensure that no data corruption occurs.  VMFS supports SCSI reservations and atomic test and set (ATS) locking. For storage devices that support hardware acceleration, VMFS uses the ATS algorithm, also called hardware assisted locking. In contrast with SCSI reservations, ATS supports discrete locking per disk sector.
