How much cache is available in a VPLEX VS2 dual engine setup?

In a VPLEX VS2 dual engine setup, each engine is fixed at 72GB of cache, with 36GB per director. Since a dual engine setup contains two engines, the total available cache would be:

72\ GB\ (per\ engine) \times 2\ (engines) = 144\ GB72 GB (per engine)×2 (engines)=144 GB

However, as each engine contains two directors, and each director has 36GB of cache, the total cache available in a dual engine setup would be:

36\ GB\ (per\ director) \times 4\ (directors) = 144\ GB36 GB (per director)×4 (directors)=144 GB

Therefore, the total cache available in a VPLEX VS2 dual engine setup is 144 GB1.
