Abstract: Techniques are provided for real-time server testing in a production environment. Unlike traditional testing frameworks, embodiments of the present invention enable a server in production to be tested using live messages received from users. This eliminates the need to design and write test scripts to cover various scenarios and enables the server to be tested under live conditions. A test controller executing on the server under test can receive message attributes from a test client that define the types of messages to be used for a particular test. The test controller can identify live messages as they are received by the server that match the message attributes. The messages can be processed by the server in real time and then tested according to message tests received from the test client.

Abstract: Techniques for incrementally increasing media size in data storage systems using grid encoded data storage techniques are described herein. A grid of shards is created where each shard of the grid of shards has a first index, a second index and each shard also has an associated storage device configured with a storage capacity that is large enough to store the largest set of data on a shard. Upon determining to replace the storage devices of the grid with storage devices that have a different storage capacity, the storage devices can be incrementally replaced within the grid by first padding each shard of the grid of shards with a set of data values, replacing a data shard storage device with a device of the different storage capacity, and replacing a set of derived shard storage devices with devices of the different storage capacity.

Abstract: A method that prevents unnecessary data recovery includes receiving, at a data processing device, a status of a resource of a distributed system. When the status of the resource indicates a resource failure, the method includes executing instructions on the data processing device to determine whether the resource failure is correlated to any other resource failures within the distributed system. When the resource failure is correlated to other resource failures within the distributed system, the method includes delaying execution on the data processing device of a remedial action associated with the resource. However, when the resource failure is uncorrelated to other resource failures within the distributed system, the method includes initiating execution on the data processing device of the remedial action associated with the resource.

Abstract: For failure interval determination, a determination module determines a failure interval for transactions in a transaction queue based on a number of processed transactions. A transaction timeout module fails a first transaction in response to the first transaction not processing within the failure interval.

Abstract: Embodiments of the present invention utilize a dual buffer size threshold system for raising interrupts that allows DUT testing systems to perform real-time buffer memory allocation procedures in an on demand basis. Using dual interrupt threshold systems in the manner described by embodiments of the present invention, DUT testing systems can reduce the need to decide on a single buffer size threshold when testing a set of DUTs that separately provide different amounts of fail data relative to each other. As such, embodiments of the present invention can minimize the overhead processing spent on interrupt handling while also reducing the amount wait time needed for the data processing module to process fail data for each DUT. Thus, embodiments of the present invention can increase the use of tester resources more efficiently while decrease the amount of time a tester system spends collecting and/or analyzing fail data for a set of DUTs during a testing session.

Abstract: Embodiments use data shuttle devices to restore erasure-coded data in a distributed storage environment. In some embodiments, a first data shuttle is communicatively coupled to a first node of the storage environment. On the data shuttle, first restoration data is generated from a first erasure-coded data portion stored on the first node. The first data shuttle or a second data shuttle is communicatively coupled to a second node of the storage environment. On the data shuttle at the second node, second restoration data is generated from a second erasure-coded data portion stored on the second node. Subsequent to transporting the first or second data shuttle from at least one of the other nodes to a third node, a third erasure-coded data portion is restored at the third node. The third erasure-coded data portion is generated via an erasure-coding process from one or more of the first or second restoration data.

Abstract: Techniques for enabling virtual machine (VM) recovery on non-shared storage in a single virtual infrastructure management server (VIMS) instance are provided. In one set of embodiments, a VIMS instance can receive an indication that a VM in a first cluster of the VIMS instance has failed, and can determine whether the VM's files were being replicated to a storage component of the VIMS instance at the time of the VM's failure. If the VM's files were being replicated at the time of the failure, the VIMS instance can search for and identify a cluster of the VIMS instance and a host system within the cluster that (1) are compatible with the VM, and (2) have access to the storage component. The VIMS instance can then cause the VM to be restarted on the identified host system of the identified cluster.

Abstract: One or more techniques and/or systems are provided for dynamic mirroring. A first storage node and the second storage node within a first storage cluster may locally mirror data between one another based upon a local failover partnership. The first storage node and a third storage node within a second storage cluster may remotely mirror data between one another based upon a primary disaster recovery partnership. If the third storage node fails, then the first storage node may remotely mirror data to a fourth storage node within the second storage cluster based upon an auxiliary disaster recovery partnership. In this way, data loss protection for the first storage node may be improved, such that the fourth storage node provide clients with access to mirrored data from the first storage node in the event the second storage node and/or the third storage node are unavailable when the first storage node fails.
