When using Continuous Access EVA in a VMware ESX environment, HP recommends setting a preferred

controller to virtual disks configured in a DR group and reflecting the configured affinity on the ESX

multipathing configuration. As shown in Figure 14, you can still balance the LUN across multiple HBA ports,

but you must ensure that the destination address points to a port on the owning controller to avoid excessive

proxy reads.
