A distributed storage system node is disclosed. The distributed storage system node may include at least one storage device, which may act as the primary replica for data subject to an Input/Output (I/O) request. A cost analyzer may calculate a local estimated time required to complete the I/O request at the primary replica, and a remote estimated time required to complete the I/O request at a secondary replica of the data. An I/O redirector may direct the I/O request to either the primary replica or the secondary replica based on the local estimated time required and the one remote estimated time required.

IO redirection methods with cost estimation

A method includes: receiving an operational command directed to a solid-state drive (SSD) and a security credential; issuing an asynchronous event from the SSD to an authentication agent including the security credential and a security certificate, wherein the security certificate is encoded based on the security credential and is stored in the SSD; forwarding the security credential and the security certificate from the authentication agent to an authentication server; validating the security certificate based on the security credential at an authentication server; providing a validation response from the authentication server to the authentication agent; forwarding the validation response from the authentication agent to the SSD; and executing the operational command based on the validation response.

System and method for authenticating critical operations on solid-state drives

A storage device capable of providing instructions to modify a cooling system in support of its own operations is described. The storage device may include data storage to store data. The storage device may also include one or more operation sensors to determine a change in the operating conditions of the storage device. Finally, the storage device may include a transmitter to transmit the change in the operation conditions of the storage device to a Thermal Management System (TMS).
