Ensure your servers follow VMware's Best Practices Guide for SQL Server.

Specifically, ensure the VMs running SQL Server have 100% of their memory and CPU reserved in VMware.  Ensure you're using the PVSCSI (para-virtualized SCSI) adapter for SQL Server RDMs or Virtual Disks.  Try to use as many PVSCSI adapaters as you can since that will increase the number of disk queues available to SQL Server.
