Data Storage Interfaces

Schedule for this course

1 Day Course

This course is a remake of our successful Data Storage Interface course; adding new interfaces and showing how the interfaces compare and contrast with one another. This new course is even more for managers and decision makers who need a quick, accurate and knowledgeable overview of storage interfaces. This course avoids burdening participants with the highly technical details, focusing instead on the highlights of each interface and the difference, similarities, and performance tradeoffs among them.

The instructors for this course teach the more in-depth, technical courses and can explorer with the class more information on individual interfaces as the interest arises and time permits.

No previous knowledge of any interface is assumed. Our advanced courses on specific interfaces are recommended for those seeking more in-depth and comprehensive information.
