Any idea of what performance impact I could expect by lumping all my available volume pairs into a single Asynchronous consistency group vs splitting them up into 3 or 4 consistency groups.
I understand the only limitation is the number of volume pairs - 4096 max in one consistency group. Does anyone know how performance would be impacted with increase in volume pairs ( or size of storage - 1 consistency group of 20 Tb instead of 4 consistency group of 5 Tb ?)
Any inputs would be greatly appreciated.
