| The THOR Database System is a scaleable, open, parallel-processing, object relational database management
system (ORDBMS) for the client-server environment. THOR is a complete system, comprising the THOR SQL objectManager™ software – an SQL implementation designed to run on parallel shared-nothing hardware – and the THOR MPP Data Server™ hardware – simple, off-the-shelf hardware optimized to provide a cost-effective platform for the SQL objectManager software. SQL objectManager is the only advanced scaleable open parallel object/relational DBMS optimized to run on the parallel hardware architecture. The SQL objectManager software supports the Sybase Open Server and the Open Database Connectivity (ODBC) standard. SQL objectManager emulates TRANSACT-SQL, the Sybase dialect of SQL, making it compatible with numerous existing applications and application generators. |  |

| Network Gateway Requirements | UNIX – SCSI-II Adapter |
The THOR MPP Data Server is tuned for VLDB uses. It uses leading edge PowerPC technology with Ultra-SCSI disk drives. The modular packaging lets you easily scale your implementation to meet your present and future VLDB data processing requirements.
The THOR MPP Data Server hardware comprises a matrix of data processing nodes. Each node has its own dedicated processor, memory and disks. The nodes are linked together in a toroidal mesh, so the machine is capable of achieving a high degree of parallelism in searching, sorting and updating large amounts of data with extremely low latency.
A THOR module contains four nodes; a tower contains six modules, or 24 nodes. In THOR's initial release, up to 12 towers or 288 nodes can be connected. The system shown above displays four modules, or 16 nodes, while also illustrating the hardware's scalability.
