VMware introduced the paravirtual SCSI  (PVSCSI) diskcontroller which is available for virtual machines. In this knowledgebase article the best practise is given:

  • PVSCSI is best for workloads that drive more than 2000 IOPS and 8 outstanding I/Os.
  • LSI Logic is best for workloads that drive lower I/O rates and fewer outstanding I/Os. 

    • A technical explanation can be found at the Pivot Point blog
