DESCRIPTION
Business drivers affect the performance expectations of enterprise applications. Data infrastructure must be flexible and agile to support these emerging performance and availability requirements. This session will show you how to build a data infrastructure using NetApp's flash and clustering technologies that is flexible enough to accommodate those changing demands. The session will cover how to combine NetApp's enterprise flash technology (including host-based flash, controller-based caching, hybrid disk shelves, and all-flash arrays) with NetApp's Clustered Data ONTAP to allow dynamic re-optimization of application performance, with an eye on how workload characteristics drive architectural decisions.

Agile Data Infrastructure
Migrate individual VMs between hosts & datastores
Migrate datastores across performance tiers– Address changing performance requirements– Correct over/under provisioning issues– Change SLA’s over tenant lifecycle– Non-disruptive hardware & software refreshes

Server Cache for Data ONTAP
Performance of Flash, Data Management of ONTAP
Increased server utilization and throughput• CPUs spend more
time working, less time waiting on IO
• Increases server throughput by up to 80%
Improved app performance and density• Reduces app
latency up to 90%• More workload on
existing infrastructure
• Reduces demand on backend storage
Leverageshared storage• Bring server
flash under management of Data ONTAP
• Availability and reliability
• Data coherency with ONTAP

Introducing NetApp Flash Accel
Flexible Deployment Software only, compatible with server PCI-e
flash or SSD drive; choose your own flash device
Sustainable High Performance Intelligent data coherency: block-level invalidation
rather than flush entire cache Persistent cache across VM / server reboots
Extend ONTAP value into the server Mechanism for deeper ONTAP integration in the
future

Data Coherency Implications with Caching
What is data coherency? Consistency between data
in cache and data on disk
Why is datacoherency important? Caches that don’t recognize
changes to the primary data copy (e.g. via SnapRestore®) will cause data corruption issues

DataCoherency
• When does the cache invalidate data?• Is the cache a write-through or a write back cache?• Does the cache retain data across a reboot etc?
Key criteria include
Flash Accel: Snapshot Coherency
18
Restore snapshot• Offline - Unmount
device and disconnect from VM
• Online – via SnapDrive
• Read metadata stored with snapshot• Compare snapshot state metadata with
current cache state metadata• Invalidate changed blocks between the
two states and rollback cache to snapshot state
• Store metadata of cache state at point-in-time along with snapshot in ONTAP
