Zumastor Linux Storage Server
Zumastor provides Linux with network storage functionality suited to a medium scale enterprise storage role: live volume backup, remote volume replication, user accessible volume snapshots and integration with Kerberized network filesystems. This paper examines the design and functionality of the major system components involved. Particular attention is paid to the subjects of optimizing server performance using NVRAM, and reducing the amount of network bandwidth required for remote application using various forms of compression. Future optimization strategies are discussed. Benchmark results are presented for currently implemented optimizations.
