Abstract
Systems and methods are provided for controlling load on a server hosting block storage volumes by dynamically controlling latency for input/output (I/O) operations to the block storage volumes. The system can selectively inject synthetic latency into the I/O operations according to how the server is loaded, thus enabling control of server load. For example, when the server is overloaded, additional synthetic latency can be injected into I/O operations to counteract overloading. This synthetic latency can then be removed when the server is no longer overloaded. Modifications of synthetic latency can be targeted to individual clients, individual types of I/O operations, or both, facilitating targeted performance shaping for servers hosting block storage volumes.
