....a high degree of node isolation is achieved. A node has an Intel i486 1 processor, 16 MB of memory, 4 SCSI bus controllers and d 1 communication channels (d is the dimension of the hypercube) Each node is contained on a single board and makes up a customer replaceable unit. A 1000 TPS ([17]) HypRa server has 64 nodes. Figure 1 shows a functional model of the different components of a node and the replaceable units. The notation and concepts are based on [11] A node has 1 i486 is a trademark of Intel Corporation 3 primary tasks: communication, data storage and database services. ....

....HypRa database server (1024 nodes) can handle a transaction load of up to more than 20,000 TPS, i.e. it is able to handle at least 20,000 simultaneous debit credit bank transaction and respond to each in less than one second. The database volumes are according to the standardized test published in [22] and [23] The complex query performance is indicated by a join capacity of more than 1,500 megabytes second. ffl Scalability Due to the hardware interconnection topology and the homogeneous software design a HypRa database server can be configurated with from 4 to 1024 nodes. This gives a ....
