Distributed, but used like a shared storage.
SLIDE 6
Designed for VM Block Storage
- Virtual disk image is often large (GB or TB)
- Single Reader and Single Writer
- R/W workload are in the units of sectors
- VM can be migrated, but not often
- Thin provision is required
- Strong consistency is required
Software-only Solution
