Canister-to-canister serial connection for high performance enterprise storage system product

An existing product for a high performance enterprise storage system has many components, including two canisters for redundancy. When one canister fails or experiences network interferences, it may become necessary to serial connect into that component to repair the issue. This process requires manual labor and can take time to perform. It also requires special equipment, a personal computer (PC), and a micro-Universal Serial Bus (USB) to USB converter (which a field engineer might not

have on-hand).

A method is needed that allows the enterprise storage system product to introduce inherent hardware/software and allow serial canister-to-canister communication. With this approach, a technician can connect to the working canister through a secure shell (SSH), and then serial into the broken canister for servicing.

The novel contribution is a method that establishes the serial connection as a kind of two-way (full duplex), so that either node can be directly utilized to take over control of the other failed canister. This new serial connection is named as "internal serial"

while traditional serial line is "external serial".

With the new method, user does need any extra device, only call a command to enable the "ready connect" serial line between the two canisters.

The new method also enables a door save time to "re-fresh/re-flash", which allows the user to directly "clone" all components from software, firmware, or a full upgrade of the image from the good canister to the bad/failed canister. It can also take over control of the failed canister to read/adopt a new image from USB drive of any canister.

In addition, in the traditional case in which both canisters have failed, the user has to independently serial connect to each node. With the new method, the user only has to connect to one of the external serial lines, recover it, and then use the same serial line to invoke all fix commands needed to rescue the other canister...
