FlexCache™ Overview Storage performance accelerator 25 March 2017 FlexCache™ Overview Storage performance accelerator Cache storage protocol Supports NFS v2/v3 Cache architecture Memory and disk Volume granularity Write-through Origin System Origin Volume FlexCache Volume NFS Clients FlexCache System 2

FlexCache Overview Significant value across various workloads Shared data sets Repeated access Random reads High IOPS/concurrency Across different verticals Financial EDA Software build Movie rendering Energy exploration Biotech

FlexCache Use Cases Three primary: (A) Scale out performance (B) Reduce WAN latency (C) Offload resources Also: Tiered storage FlexCache Volumes NFS Clients Origin System Caching Systems Origin Volume (A) FlexCache Volume (C) Caching System WAN WAN (B) NFS Clients

Scale Out Performance Challenges FlexCache™ increases IOPS Benefits 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 FlexCache Volume SCALE OUT NFS Clients Origin System Caching System Origin Volume …… Caching System FlexCache Volume

Reduce WAN Latency Challenges FlexCache™ reduces WAN latency Benefits 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 Origin Volume FlexCache Volume Caching System WAN WAN Origin System NFS Clients

Offload Resources Challenge FlexCache™ offloads resources Benefits 25 March 2017 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 FlexCache Volumes NFS Clients Origin System Caching Systems Origin Volume FlexCache Volume Caching System WAN WAN NFS Clients 7

FlexCache as Tiered Storage Challenge Provide cost-effective tiered storage FlexCache paradigm Primary is FlexCache Secondary is origin Migration is application driven Benefits No migration policies Sharing data is simple Data management on secondary Primary 1 (FlexCache) NFS Clients Secondary (Origin) Cached Data Fewer Drives Data A’, B’ App Drives Migration Primary 2 (FlexCache) NFS Clients All Data Low Cost Drives Data A, B, C Cached Data Fewer Drives Data B’, C’
