Abstract: Techniques for performing I/O load balancing are provided. In one embodiment, a computer system can receive an I/O request destined for a storage array, where the computer system is communicatively coupled with the storage array via a plurality of paths, and where the plurality of paths include a set of optimized paths and a set of unoptimized paths. The computer system can further determine whether the I/O request can be transmitted to the storage array via either an optimized path or an unoptimized path, or solely via an optimized path. The computer system can then select a path in the plurality of paths based on the determination and transmit the I/O request to the storage array via the selected path.

Abstract translation: 提供了执行I / O负载平衡的技术。 在一个实施例中，计算机系统可以接收去往存储阵列的I / O请求，其中计算机系统经由多个路径与存储阵列通信地耦合，并且其中多个路径包括一组优化的路径，以及 一套未优化的路径。 计算机系统可以进一步确定I / O请求是否可以经由优化的路径或未优化的路径，或者仅经由优化的路径发送到存储阵列。 计算机系统然后可以基于该确定来选择多个路径中的路径，并且经由所选择的路径将I / O请求发送到存储阵列。
