Size

The TIBCO BusinessEvents® Extreme product installation will make use of approximately 1 gigabyte of disk space.

Deployed, each TIBCO BusinessEvents® Extreme node's disk space is determined mostly by the size of the shared memory. By default this size is 512 megabytes and the shared memory is an ordinary file system file, which is memory-mapped by the TIBCO BusinessEvents® Extreme runtime. There is also an option to use System V Shared Memory instead of a file. In this case, the shared memory does not use any disk space.

	Deploying the shared memory file in a networked file system (e.g. NFS) is not supported.

After system startup, TIBCO BusinessEvents® Extreme , by default, will generate very little disk I/O, most of it involved in logging the invocation of administrative commands.

Application specific logging or generation of disk data also needs to taken into account when choosing disk size.

Number

By default, a single disk is capable of supporting a TIBCO BusinessEvents® Extreme node.

Disk I/IO speeds need to be considered when either change logging or application specific disk I/O will occur. If a single disk does not have the sufficient space or performance characteristics, the I/O may be spread across multiple disks either through configuration of the file locations, or by using a volume manager to present multiple disks as a single logical disk to TIBCO BusinessEvents® Extreme .

Partitioning

TIBCO BusinessEvents® Extreme does not have specific partitioning requirements.

	Using multiple partitions does not improve the performance characteristics of a single disk.
