A method and system is disclosed for resolving a single server bottleneck. Logically associated data is typically collocated within a single filesystem or a single block device accessible via a single storage server. A single storage server can provide a limited I/O bandwidth, which creates a problem known as “single I/O node” bottleneck. The method and system provides techniques for spreading I/O workload over multiple I/O domains, both local and remote, while at the same time increasing operational mobility and data redundancy. Both file and block level I/O access are addressed. |
