The chassis may be configured to receive a plurality of modular information handling systems. The one or more chassis management controllers may be configured to receive a storage management command, encapsulate the storage management command in a first datagram, and communicate the first datagram to a switch management controller housed in the chassis. The switch management controller may be configured to extract the storage management command from the first datagram, identify a storage controller associated with the storage management command, and communicate an input/output control request to the storage controller based on the storage management command. ## Claims ### Claim 1 A system comprising a switch management controller configured to: receive a first datagram having encapsulated therein a storage management command; extract the storage management command from the first datagram; identify a storage controller associated with the storage management command; and communicate an input/output control request to the storage controller based on the storage management command. ### Claim 2 (depends on 1) The system of claim 1, wherein the switch management controller is housed in a chassis, and the first datagram is received by the switch management controller from a chassis management controller housed in the chassis. ### Claim 3 (depends on 2) A system according to claim 2, the switch management controller configured to receive the first datagram from the chassis management controller via a private network internal to the chassis. ### Claim 4 (depends on 2) The system of claim 2, the command originating from a management console communicatively coupled to the chassis management controller. ### Claim 5 (depends on 1) The system of claim 1, the first datagram comprising an Ethernet frame. ### Claim 6 (depends on 1) The system of claim 1, the switch management controller configured to receive the first datagram via Transmission Control Protocol/Internet Protocol. ### Claim 7 (depends on 1) The system of claim 1, the switch management controller configured to communicate the input/output control request to the storage controller via a switch. ### Claim 8 (depends on 7) The system of claim 7, the switch compliant with Peripheral Component Interconnect Express. ### Claim 9 (depends on 1) The system of claim 1, the switch management controller further configured to: receive a reply to the input/output control request from the storage controller; encapsulate the reply in a second datagram; and communicate the second datagram to an information handling resource from which the first datagram was received. ### Claim 10 (depends on 9) The system of claim 9, wherein the switch management controller is housed in a chassis, and the information handling resource comprises a chassis management controller housed in the chassis. ### Claim 11 A method comprising: receiving a first datagram at a switch management controller; extracting a storage management command from the first datagram; identifying a storage controller associated with the storage management command; and communicating an input/output control request from the switch management controller to the storage controller based on the storage management command. ### Claim 12 (depends on 11) The method of claim 11, wherein the switch management controller is housed in a chassis and wherein receiving the first datagram comprises receiving the first datagram from a chassis management controller housed in the chassis. ### Claim 13 (depends on 12) The method of claim 12, the command originating from a management console communicatively coupled to the chassis management controller. ### Claim 14 (depends on 12) The method of claim 12, wherein receiving the first datagram comprises receiving the first datagram via a private network internal to the chassis. ### Claim 15 (depends on 11) The method of claim 11, the first datagram comprising an Ethernet frame. ### Claim 16 (depends on 11) The method of claim 11, wherein receiving the first datagram comprises receiving the first datagram via Transmission Control Protocol/Internet Protocol. ### Claim 17 (depends on 11) The method of claim 11, wherein communicating the input/output control request comprises communicating the input/output control request to the storage controller via a switch. ### Claim 18 (depends on 17) The method of claim 17, the switch compliant with Peripheral Component Interconnect Express. ### Claim 19 (depends on 11) The method of claim 11, further comprising: receiving a reply to the input/output control request from the storage controller; encapsulating the reply in a second datagram; and communicating the second datagram to an information handling resource from which the first datagram was received. ### Claim 20 (depends on 19) The method of claim 19, wherein the switch management controller is housed in a chassis, and the information handling resource comprises a chassis management controller housed in the chassis.
