Scale Out Performance

Challenges Compute farms have huge demand Storage performance dictates grid

growth

FlexCache™ increases IOPS Scales capability for shared data Balances client load across multiple

caching systems

Benefits Extensive scalability No need to replicate/mirror data

Reduce WAN Latency

Challenges Wide area networks are slow Ensure nodes are always

processing

FlexCache™ reduces WAN latency

Caches data near client Faster access times Avoids the overhead of replication

Benefits Reduced latency for NFS clients Nondisruptive Ease of management Disk-space efficient Reduces WAN utilization

Offload Resources

Challenge Overloaded storage system or

network infrastructure

FlexCache™ offloads resources Origin available for other tasks NFS ops served from cache

Benefits Offloads storage Offloads network Simplifies administration
