Why each option
This question asks to identify two key architectural enhancements of the HP 3PAR StoreServ 7400 platforms over older S-Class arrays. The correct enhancements highlight fundamental improvements in the operating system and processing architecture.
The shift to a 64-bit operating system in the 3PAR StoreServ 7400 series significantly increased the addressable memory and allowed for greater scalability in terms of performance and storage capacity. This architectural change is crucial for handling modern data demands and larger array configurations.
While logical disk region sizes might change with generations, this specific detail is not typically highlighted as a primary notable architectural enhancement compared to OS architecture or ASIC design for the entire platform.
The Gen4 ASIC (Application-Specific Integrated Circuit) incorporated tightly coupled cache-coherent clustering, which is fundamental to 3PAR's ability to scale performance and maintain high availability across multiple controllers. This integrated design allows for efficient, low-latency communication and data sharing within the system, enhancing overall system throughput and responsiveness.
While write cache mirroring is crucial for 3PAR, the specific N+N implementation across 7x00 controllers is a feature detail rather than a fundamental architectural enhancement of the platform's core design.
Support for higher Fibre Channel speeds like 16Gb is a feature enhancement related to connectivity, not a core architectural enhancement of the array's internal processing or operating system design.
