Patent number: 11847226Abstract: Technologies are described herein for providing a Baseboard Management Controller (“BMC”)-based security processor. The disclosed BMC-based security processor can provide a hardware Root of Trust (“RoT”) for a computing platform without the addition of specialized silicon to the platform and while minimizing the number of attack points. The disclosed BMC-based security processor can also provide functionality for securely filtering requests made on certain buses in a computing platform. Through implementations of the features identified briefly above, and others described herein, various technical benefits can be achieved such as, but not limited to, increased security as compared to previous computing systems that utilize a BMC to provide a hardware RoT and reduced complexity and cost as compared to previous computing systems that utilize a separate hardware device, such as a Field Programmable Gate Array (“FPGA”) or a microcontroller, to provide a hardware RoT.Type: GrantFiled: November 25, 2020Date of Patent: December 19, 2023Assignee: AMERICAN MEGATRENDS INTERNATIONAL, LLCInventors: Stefano Righi, Umasankar Mondal, Sanjoy Maity

Patent number: 11513984Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes a baseboard management controller (BMC). The BMC receives a first message from a first remote device on a management network. The BMC determines whether the first message is directed to a storage service or fabric service running on a host of the BMC. The host is a storage device. The BMC extracts a service management command from the first message, when the first message is directed to the storage service or fabric service. The BMC sends, through a BMC communication channel to the host, a second message containing the service management command to the host. The BMC communication channel established for communicating baseboard management commands between the BMC and the host.Type: GrantFiled: February 4, 2020Date of Patent: November 29, 2022Assignee: AMERICAN MEGATRENDS INTERNATIONAL, LLCInventors: Anurag Bhatia, Jason Messer, Joseprabu Inbaraj, Clark Kerr, Sanjoy Maity

Patent number: 11416428Abstract: A computer system includes a BMC and a host of the BMC. The BMC receives a first message from a first remote device on a management network. The BMC determines whether the first message is directed to a storage service or fabric service executed on a main processor of a storage controller of the host. The host is a storage device. The storage controller includes an RDMA controller in communication with the main processor through an internal communication channel of the storage controller. The RDMA controller is managed by the storage service. The BMC extracts a service management command from the first message, when the first message is directed to the storage service or fabric service. The BMC sends, through a BMC communication channel established for communicating baseboard management commands between the BMC and the host, a second message containing the service management command to the host.Type: GrantFiled: February 4, 2020Date of Patent: August 16, 2022Assignee: AMERICAN MEGATRENDS INTERNATIONAL, LLCInventors: Anurag Bhatia, Jason Messer, Sanjoy Maity

Patent number: 11132315Abstract: A computer system includes a BMC and a host of the BMC. The BMC receives a first message from a first remote device on an existing out-of-band management network. The BMC determines whether the first message is directed to a storage service or fabric service running on the host, the host being a storage device. The storage service provides access to user data stored on one or more storage devices connected to the host via a storage network that is isolated from the management network. When the first message is directed to the storage service or fabric service: the BMC extracts a service command from the first message; the BMC sends, through a BMC communication channel to the host, a second message containing the service command to the host. The BMC communication channel has been established for communicating baseboard management commands between the BMC and the host.Type: GrantFiled: February 4, 2020Date of Patent: September 28, 2021Assignee: AMERICAN MEGATRENDS INTERNATIONAL, LLCInventors: Anurag Bhatia, Sanjoy Maity
