capacity, performance and scalability. Look at specs for each platform and you will see the difference just in terms of hardware scalability. All the extra engines in VMAX bring a lot of performance with them (DAs, FAs, Cache, CPUs)

VNX is A/P and VMAX is A/A storage controller architecture

Active/Passive, Active/Passive. Generally speaking. in VNX, only one SP owns LUN and proceed I/O operation. VMAX does it parallel through different directors.

what is the base technical difference?

please let know what is A/P and what is A/A

and software

so, only hardware difference between vnx and vmax?

NP. Please also help to mark the helpful and correct posts and if applicable, this will help assist others with similar query. Thank you.

helpful answer. thank you.

To me the difference is almost all software, with the hardware difference being the ability to scale beyond one director pair (engines in VMAX).

Both use Intel CPUs and memory, etc.
