The document discusses HP StorageWorks enterprise file services. It describes how the HP Clustered Gateway provides high availability through failover within 5 seconds and scalability through the ability to add nodes for nearly linear performance increases. The EFS WAN Accelerator can consolidate remote office servers and storage in the data center and provide LAN-like file access over the WAN. It estimates the EFS WAN Accelerator can provide a 30-40% reduction in total cost of ownership through consolidation and optimization.

7. HP StorageWorks Enterprise File Services Cluster—optimized scalability & availability Traditional NAS / filer design Multiple paths: No bottleneck Symmetrical cluster file system Bottlenecks: Metadata server and Hot Spots Distributed file system and metadata server designs Clustered File System Design: Built into shared data and shared storage design Requires redundant data, storage, and servers Traditional clustering prone to error, downtime Availability: Performance increases linearly as scaled out Metadata bottlenecks and hot spots can cause problems as they are scaled out Limited — requires distinct file systems for each node. Clustering is for HA not performance Performance: Scales to 16 nodes Scales to many nodes Scales to two nodes Scale-out:
