Shared Storage Access
The availability of clustered file systems has dramatically enhanced shared file-level access to SAN-based storage.
Shared storage access is often required by workstations and servers employing a mix of Operating Systems. SAN, or clustered file systems level the field for access by offering a common file system that is simultaneously accessible by differing systems. For example, clustered file systems enable SAN-connected workgroups or servers using UNIX, LINUX, MAC OS-X and Windows to share concurrent, direct, high-performance block-level access to storage resources on a SAN.
Benefits of this architecture are:
- Elimination of data movement over the LAN
- Wire-speed storage access
- Simplified block-level access controls
- Universal file-system journaling
- Concurrent access without NAS protocol overhead
- Enhanced work-flow efficiencies
Clustered file systems are also useful for:
- SAN/NAS convergence and NAS workload distribution
- Distributed web-server farms
- Enabling SAN-based, HSM installations
- Supporting LAN-free backup capabilities
InfraStor's breadth of experience in SAN implementations and shared storage access capabilities ensures that our customers maximize the return on their storage investments for such high-performance applications as:
