Talk:Storage virtualization
The Storage Virtualization topic is currently a stub. I'm adding this comment to outline content I'd like to see:
- Overview
- Definition
- Key concepts
- Address space remapping
- Metadata
- I/O redirection
- Capabilities
- Replication
- Mobility
- Pooling
- Volume management
- Benefits
- Nondisruptive data migration
- Improved utilization (pooling + migration)
- Fewer points of management
- Risks
- Backing out a failed implementation
- Interoperability/vendor support
- Complexity
- Metadata management
- Performance/scaleability
- Implementation approaches
- Host-based
- Logical volume manager
- File systems (links, CIFS/NFS)
- Automatic mounting (autofs)
- Storage device-based
- RAID
- Caching
- Array aggregation/consolidation
- Network-based
- Applicance-based vs. switch-based
- In band vs. out of band
- SAN (block) vs. NAS (file)
- Host-based
Notice the complete lack of vendor and product references. Some of the storage virtualization technologies are still emerging and others are waning, so it would be hard to give a fair treatment to all. If anyone wants to take that on, be my guest!
