What is bursty?
Some applications have a random access profile and it is possible that
they will access the storage in bursts. Each burst can cause a high
demand for the available resources but the average demand from this
type of application profile is very low.
Transaction processing and Database applications have this type of
What is streaming?
Some applications require sequential access to the storage. Each read
or write will request a large amount of data be transferred in one
operation. This changes the demand on the storage and the way it
needs to be configured for optimum performance will be totally different
to the configuration required for random I/O applications.
Video Streaming, Backup and Restore applications typically require
sequential access to data.
When you mix differing application profiles on the same storage port or across
the same infrastructure you need to tune the environment for the best
compromise. If you optimise the environment for a specific profile it is possible
that the other profiles will be adversely affected. The goal is make sure that all
applications meet the defined SLA.
