Operations are monitored that involve a plurality of servers coupled to a plurality of data storage enclosures via a rack-level, storage networking fabric. The servers are operable to provide data storage services utilizing the data storage enclosures via a network. The data storage enclosures each have one or more data storage devices. The servers and the data storage enclosures are mounted within a data center rack. A failed unit determined that includes a failed one of the servers or a failed one of the data storage devices within a selected one of the data storage enclosures. A replacement is found for the failed unit within the data center rack, and the replacement is established for the failed unit within the data center rack. The establishment of the replacement involves establishing a new connection via the storage networking fabric.
