Dear Shawn_K and Benjamin,
Thank you for your answers. I'm interested in offload snapshots, to get rid of as many network traffic as possible. As I read:
"Through VASA, vSphere and the underlying storage system establishes a two-way out-of-band communication to perform data services and offload certain virtual machine operations to the storage system. For example, operations such as snapshots and clones can be offloaded."
However other documentation shows that offload operations rather based on VAAI. As I can see in vmware HAL the VAAI supported on msa 2552. Unfortunately I'm little confused with VAAI and VASA in case of msa.
What I would like to use with device is logical grouping of storage controllers, and keep snapshot/clone operations at storage level (and as many functions as I can).
Could you please help me to clarify this?
Thank you very much
