BMC is operable to generate the responses to the BMC requests received from the coordination interface and to send the responses to the coordination interface. ### Claim 9 (depends on 8) The rack server system defined in claim 8 wherein the one or more queues comprises a plurality of queues, wherein each of the plurality of queues stores requests having one or more matching parameters, and further comprising an information forwarder to forward information received from the BMC in response to one request as a response to one or more other queued requests in one of the plurality of queues. ### Claim 10 (depends on 9) The apparatus defined in claim 9 further comprising data check logic to generate an indicator to specify whether a time the information is received from the BMC is within a timing completion threshold for other queued requests, and wherein the information forwarder only forwards the information as the response to the one or more other queued requests for the one or more other queued requests for which the indicator indicates the time the information is received is within the timing completion threshold. ### Claim 11 (depends on 9) The apparatus defined in claim 9 further comprising authentication check logic to authenticate each of the one or more queued requests, and wherein the information forwarder only forwards the information as the response to the one or more other queued requests for each of the one or more other queued requests that has been authenticated by the authentication check logic. ### Claim 12 (depends on 8) The apparatus defined in claim 8 wherein the command submitter is operable to submit one BMC request at a time. ### Claim 13 (depends on 12) The apparatus defined in claim 12 wherein the command submitter is operable to
