3 scalability for network and storage. We use lowlevel protocol and hierarchical striping to realize 1 separation of bulk data transfer and local accesses by caching, 2 filesystem transparency, 1.. interoperable whatever in higher layer than disk driver, including file system. In addition, Data Reservoir can be used as an ordinary UNIX server in local network without any modification of server softwares. This paper shows our design, implementation using iSCSI protocol and their performances for both 1Gbps model in the real network and 10Gbps model in our laboratory.
We use lowlevel protocol and hierarchical striping to realize 1 separation of bulk data transfer and local accesses by caching, 2 filesystem transparency, 1.. We propose data sharing facility for data intensive scientific research, Data Reservoir which is optimized to transfer huge amount of data files between distant places fully utilizing multigigabit backbone network. This paper shows our design, implementation using iSCSI protocol and their performances for both 1Gbps model in the real network and 10Gbps model in our laboratory. interoperable whatever in higher layer than disk driver, including file system.
