Storage processor for symmetrix
Hi,
Is there is any concept of storage processor like we see in clarrion or Controller we see in hitachi arrays for symmetrix.

I don't know exactly how does HDS storages behave .. In CX world the storage processor is the main engine that protects data and virtualizes the physical disks, presenting you "virtual" luns that you can configure at your will. In DMX there is no "storage processor" .. instead you have a matrix of connections that allows frontend adapters to access a shared cache. The same shared cache is seen also from all your backend directors.
Frontend director is responsible of the host-storage interface. backend processors are responsible of the storage-to-disks interface. Obviously I refer to the "engine" in the DMX when I say "storage".
So in DMX world there are different "processors" all running our Enginuity Operating Environment and working together to virtualize your physical drives and present luns to your hosts. The main difference is that in CX terms, the "storage processor" is a one-man-band doing almost everything. In DMX world you have different processors working together and sharing a common cache (in a true SMP architecture).

The following links for the DMX-4 for example:
Home > Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > Symmetrix DMX Family > Symmetrix DMX-4 > General Reference
Symmetrix DMX-4 Product Guide
The DMX-4 Architecture section and the DMX-4 operations sections in particular.
