Systems and methods for supporting inter-chassis manageability of nvme over fabrics based systems

A data storage system comprising:

• a switching Ethernet SSD chassis comprising an Ethernet switch, a baseboard management controller (BMC), and a management LAN port;
• and
• a first switchless Ethernet SSD chassis and a second switchless Ethernet SSD chassis,
• wherein each of the first switchless Ethernet SSD chassis and the second switchless Ethernet SSD chassis comprises an Ethernet repeater, a BMC, a management LAN port that is connected to each other and to the management LAN port of the switching Ethernet SSD,
• wherein the BMC of the second switchless Ethernet SSD chassis provides device information of the second switchless Ethernet SSD chassis to the BMC of the first switchless Ethernet SSD chassis via the management LAN port,
• wherein the BMC of the first switchless Ethernet SSD chassis provides device information of the first switchless Ethernet SSD chassis and the second switchless Ethernet SSD chassis to the BMC of the switching Ethernet SSD chassis via the management LAN port, and
• wherein the BMC of the switching Ethernet SSD chassis provides device information of the switching Ethernet SSD chassis, the first switchless Ethernet SSD chassis, and the second switchless Ethernet SSD chassis to a system administrator connected over a fabric network.

A method comprising:

• selecting a candidate BMC among a plurality of BMCs in a domain, wherein the domain comprises a plurality of Ethernet solid-state drive (SSD) chassis including at least one switching Ethernet SSD chassis and one or more switchless Ethernet SSD chassis;
• broadcasting to the plurality of BMCs in the domain to claim presidency of the domain;
• checking qualification of the candidate BMC based on responses received from the plurality of BMCs;
• and
• electing the candidate BMC as a president BMC of the domain based on the qualification,
• wherein the president BMC is included in a first switching Ethernet SSD chassis including a first Ethernet switch,
• wherein the president BMC collects device information of the plurality of Ethernet SSD chassis in the domain to a system administrator over a fabric network.
