SYSTEMS AND METHODS FOR FAIL-OVER WITNESS SLED OPERATIONS

Systems and methods provide witness sled hardware installed in a chassis and supported during failures using management resources of the chassis. A chassis may include data storage devices and Information Handling Systems (IHSs), each storing data redundantly to the storage devices, such in a vSAN. The witness sled provides witness functions, such as arbitrating discrepancies in the redundantly stored data. The chassis includes a chassis management controller (CMC) that maintains a copy of witness transactions stored by the witness sled based on transaction data transmitted by the witness sled to the CMC via the management signaling pathway. The CMC notifies the IHSs of witness operations supported by the CMC in response to a detected fault in the witness sled and utilizes the copy of witness transactions to process witness transactions from the IHSs while the witness sled is not operational.
