of the buses must be configured with at least four disk modules (eight disk modules per
disk enclosure). This configuration also offers full sequential performance and is more
economical to implement.
To scale up sequential transfer performance from the host, configure additional disk
arrays. This will increase the total I/O bandwidth available to the server.
Performance can also be measured by the number of I/O operations per second a system
can perform. I/Os per second are important in OLTP (on-line transaction processing)
applications. To maximize I/Os per second, configure the maximum number of disk
modules. For the same capacity, you may elect to use a larger number of 9.1 Gbyte disk
modules instead of a smaller number of higher capacity disk modules to obtain optimal
I/Os per second.
For the maximum I/Os per second, configure RAID 0/1 and the maximum

number of disk modules.
