Since storage capacities are growing and disk is available at lower cost points, many
organizations are now storing all relevant data online in disk storage for data warehousing
and business intelligence implementations. Given that disks delivering the
best performance are typically more expensive and of lower capacity, many now
deploy such disks in combination with higher capacity but lower performing (and
cheaper) disk for less frequently accessed data. Information Lifecycle Management
(ILM) in the Oracle database, particularly the ILM Assistant, first available in 2007,
provide the capability to manage such an environment.
Which Platform Deployment Solution?
In a world in which there was no limit to the amount of money you could spend on
hardware, you could make a simple decision about the most appropriate hardware:
simply choose the level of throughput and reliability you need, and go buy it! Unfortunately,
we have yet to discover the location of this kind of world, so your choice of
a hardware solution will often be a compromise.
