Abstract: Systems, apparatuses and methods provide technology for conducting silent data corruption (SDC) testing in a network including a fleet of production servers comprising generating a first SDC test selected from a repository of SDC tests, submitting the first SDC test for execution on a plurality of servers selected from the fleet of production servers, wherein for each respective server of the plurality of servers the first SDC test is executed as a test workload in co-location with a production workload executed on the respective server, determining a result of the first SDC test performed on a first server of the plurality of servers, and upon determining that the result of the first SDC test performed on the first server is a test failure, removing the first server from a production status, and entering the first server in a quarantine process to investigate and to mitigate the test failure.

Abstract: A system including a computer storage and a processor is described. The computer storage is configured to identify a stored data as protected. The processor is configured to perform speculative execution. To perform the speculative execution, the processor is configured to determine, in response to the speculative execution of an instruction to read the stored data, whether the stored data is identified as protected. In response to a determination that the stored data attempted to be read during the speculative execution is protected, the processor is configured to disallow during the speculative execution immediate successful completion of the instruction to read the stored data.
