Abstract
A group of data storage units are serially connected in a sequential data communication path to communicate read and write operations to first and second interfaces of each data storage unit in the group. A data management computer device (“filer”) manages read and write operations of the data storage units of the group through an adapter of the filer. Main and redundant primary communication pathway connectors extend from the filer to the interfaces of the data storage unit, thereby establishing redundancy through multiple pathways to communicate the read and write operations to the data storage units of the group. Main and redundant secondary communication pathway connectors extend from partner filers to the groups of data storage units associated with each partner filer, thereby further enhancing redundancy.
