• VSP G200: 0.12 PB
• VSP G400, G600, G800, VSP F400, F600, F800: 0.2 PB
For more information about capacity available for additional shared memory

You can reduce or remove shared memory if the pools for Dynamic
Provisioning, Dynamic Tiering, active flash, and Thin Image have been
deleted. When creating cascaded pairs or clone pairs, you must add shared
memory:
