Abstract: An apparatus, system, and computer readable medium are disclosed for booting a server from a shared storage system. The present invention teaches at least one server having at least one processor, a storage system having a plurality of storage drives and at least one boot volume corresponding to the at least one server, and a switch fabric having at least one switch; the switch fabric isolates boot traffic form storage traffic and enables communication between the server and the boot volume of the storage system. In some embodiments the switch fabric includes one or more partitionable switches that isolate boot traffic from storage traffic. The boot volumes may be a redundant array of storage devices. In certain embodiments, the present invention also includes devices external to the server, switch fabric, and storage system.

Abstract: For limiting data loss due to ATI or ATE, an apparatus may include a storage module, a tracking module, and a refresh module. The storage module is configured to store a risk value for a tracked storage division. The risk value indicates a risk level of data loss for the tracked storage division. The tracked storage division is one of a plurality of storage divisions of a data storage device. The tracking module is configured to update the risk value to indicate a higher risk level based on a write to a physically proximal storage division. The physically proximal storage division is within an interference range of the tracked storage division. The tracking module is configured to reset the risk value based on a write to the tracked storage division. The refresh module is configured to refresh the tracked storage division based on the risk value meeting a threshold value.
