ESS: A NEW STORAGE ARCHITECTURE FOR MID/LARGE RAID
Referring to the concept of distributed virtual disks in cluster file system, this paper proposes a new storage architecture for mid/large-scale RAID-ESS, which consists of several different-structure SubRAIDs. Clients data can migrate into optimal SubRAID dynamically according to their access characteristics; the number of SubRAIDs and the structure of each SubRAID can also be adjusted to the evolution of system load, thus the whole ESS system can always provide a virtual disk for each client to satisfy its I/O need. Simulation results demonstrate significant I/O performance advantage in ESS, compared with the traditional mid/large-scale RAID5 or RAID1 of the same storage space.
