A New Storage Test Bed and the Research Projects on it Storage Test Bed System Projects This system will be utilized in the following two research projects. Performance Analysis of Virtualized Storage Systems Capable of Automatic Load Balancing Direct comparison of performances of various access paths and protocols used in current (and may be used in future) supercomputer systems Offsite Backup Techniques for Mutual Data Storing by Universities Blade Server: IBM Bladecenter HS22 Intel Xeon X5570 (2.93 GHz) ×2, 16 GB Memory / blade #Blades: 8 Interconnect: InfiniBand 4xDDR (20Gbps) ×2 / blade I/O: 8Gbps Fibre Channel ×2 / blade Storage: IBM XIV Storage System Capacity: 27 TB Block-wise Full Mirroring + Automatic Load Balancing NAS Gateway: IBM N6040 (AMD Opteron (2.4 GHz) ×2) Supported Protocol: FC, NFS/CIFS, iSCSI Network Switch: Alaxala AX6640S Capable of Network Virtualization (Partitioning) Transparent backup based on storage virtualization technology and secret sharing scheme (e.g., an iSCSI target capable of creating and storing safe backup data on-the-fly) Safe offsite backup based on network virtualization technology Interconnect Blade Server LAN can be extended to a remote site, and the data will be stored in a “local” storage. Network Switch Data can be stored into a remote iSCSI target. There is no need for modification on applications programs if the OS is capable of iSCSI access. A Univ. FC-SAN WAN-1 Network Virtualization NAS-GW Storage Virtualization WAN-2 B College Virtualized storage can hide details of physical disk drives, and the iSCSI target can make a safe backup data on the fly. Secret sharing schemes can be employed for higher levels of security. Note that conventional iSCSI targets would just store data, and no backup would be made.
