Storage solutions
The purpose of this topic is to step you through the world of iSeries™ storage and help you make choices about which storage technologies are right for your company now, and which may be useful in the future. As your company produces a greater volume of information, and as the value of that information grows, the methods you use to protect and preserve it become vital corporate strategies. Storage has gone from being a feature of a system to being an entity unto itself. It performs several valuable functions within your enterprise, including the following:
- Availability
- Your storage solution must enable you to access your data when you need it, without exception. In some settings, such as a hospital, access to data can mean the difference between life and death.
- Integrity
- Your data must be in exactly the same condition when it returns to you as it was when it was stored. That means it must be safe from corruption, loss, and outside attack.
- Recoverability
- Your storage solution should ensure that you can recover your data in the event of a natural disaster, such as a fire, flood, or tornado.
