Flex. Cache™ Overview ¡ Storage performance accelerator ¡ Cache storage protocol – Supports NFS v 2/v 3 ¡ Cache architecture – Memory and disk – Volume granularity – Write-through © 2008 Net. App. All rights reserved. Origin System Origin Volume Flex. Cache Volume NFS Clients Flex. Cache System 2

Flex. Cache Overview ¡Significant value across various workloads – – Shared data sets Repeated access Random reads High IOPS/concurrency ¡Across different verticals – Financial – EDA – Software build © 2008 Net. App. All rights reserved. – Movie rendering – Energy exploration – Biotech 3

Flex. Cache Use Cases Three primary: ¡ (A) Scale out performance ¡ (B) Reduce WAN latency ¡ (C) Offload resources Also: ¡ Tiered storage Flex. Cache Volumes Origin System Origin Volume NFS Clients Caching Systems (A) Flex. Cache Volume Caching System (C) WAN (B) NFS Clients © 2008 Net. App. All rights reserved. 4

Scale Out Performance Challenges ¡ Compute farms have huge demand NFS Clients ¡ Storage performance dictates grid growth Flex. Cache Volume Origin System Origin Volume Caching System …… Caching System S C A L E O U T Flex. Cache Volume © 2008 Net. App. All rights reserved. Flex. Cache™ increases IOPS ¡ Scales capability for shared data ¡ Balances client load across multiple caching systems Benefits ¡ Extensive scalability ¡ No need to replicate/mirror data 5

Reduce WAN Latency Challenges Origin Volume ¡ Wide area networks are slow ¡ Ensure nodes are always processing Flex. Cache Volume Caching System Flex. Cache™ reduces WAN latency ¡ Caches data near client ¡ Faster access times ¡ Avoids the overhead of replication WAN Origin System Benefits NFS Clients © 2008 Net. App. All rights reserved. ¡ Reduced latency for NFS clients ¡ Nondisruptive ¡ Ease of management ¡ Disk-space efficient ¡ Reduces WAN utilization 6

Offload Resources Challenge Flex. Cache Volumes Origin System NFS Clients Caching Systems ¡ Overloaded storage system or network infrastructure Flex. Cache™ offloads resources Origin Volume Flex. Cache Volume Caching System ¡ Origin available for other tasks ¡ NFS ops served from cache Benefits ¡ Offloads storage ¡ Offloads network ¡ Simplifies administration WAN NFS Clients © 2008 Net.

Flex. Cache as Tiered Storage Challenge Primary 1 NFS Clients (Flex. Cache) ¡ Provide cost-effective tiered storage Secondary (Origin) Cached Data Fewer Drives Data A’, B’ App Drives Migration Primary 2 NFS Clients (Flex. Cache) All Data Low Cost Drives Data A, B, C Cached Data Fewer Drives Data B’, C’ © 2008 Net. App. All rights reserved. Flex. Cache paradigm ¡ Primary is Flex. Cache ¡ Secondary is origin ¡ Migration is application driven Benefits ¡ No migration policies ¡ Sharing data is simple ¡ Data management on secondary 8
