- Topic Area:
- Track: Enterprise Solutions
- Topic: Storage
- Type: Breakout Session
03:00 PM Duration:
- Keith Parris
- President, Integrity Computing, Inc.
- RAID technology (striping, mirroring, shadowing, RAID 5, etc.) is available as implemented in firmware at the disk controller level or in software running on host system CPUs. This session explores various implementations, pointing out their good and bad points, and providing guidance in how one can select whether a host-based or controller-based implementation (or a combination of the two) will best meet commonly-encountered performance and availability requirements.
- Understand the types of RAID technology available in controller-based and host-based implementations.
- Identify the relative strengths and weaknesses of host-based and controller-based implementations, in terms of performance and availability.
- Know how to apply the most appropriate technology to solve a given performance or availability problem.
- Prerequisites for attendees:
- Attendeed should be familiar with storage and I/O configurations in general, and with performance and availability metrics commonly applied to storage configurations.
- Required Skill Level:
For experienced professionals in application development & system management; those working on large & complex systems
