52 Product Overview
Data I/O Architecture
The internal architecture of the array controllers is designed to optimize the
speed of data transfer between the array and the host. The internal
architecture for each product is illustrated in Figures 20, 22, and 23.
The following major components are involved in the flow of data through the
array:
■
Data flow processor - manages movement of data over the internal high-
speed busses. The processor also manages the flow of data into and out of
the ECC cache.
■
ECC cache - provides temporary storage of data for high-speed access.
■
High-speed busses - provide the data path from the host to the disk media.
The N-Way bus provides the communication link between controllers for
management and redundancy.
■
FC ports - provide the interface to the host and the back-end disk
enclosures. The VA 7410 includes additional FC ports for added flexibility
and performance.
