VMware VAAI features for ESX hosts support
Data ONTAP 8.0.1 and later supports certain VMware vStorage APIs for
Array Integration (VAAI) features when the ESX host is running ESX 4.1 or
later. These features help offload operations from the ESX host to the storage
system and increase the network throughput.
The ESX host enables the features automatically in the correct environment.
You can determine the extent to which your system is using the VAAI features
by checking the statistics contained in the VAAI counters.
For more information about the VMware VAAI features for ESX hosts, see
Data ONTAP 8.0 7-Mode Block Access Management Guide for iSCSI and FC.
igroup scalability limits
Data ONTAP 8.0.1 introduces support to expand the host side scalability by
expanding the number of igroups supported on N6000 series and N7000 series
systems from 512 per controller to 1024 per controller.
