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.

15. 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

17. Data Coherency Implications with
Caching
What is data coherency? Physical Server Storage Array
 Consistency between data
in cache and data on disk Application
Why is data Cache
coherency important?
 Caches that don’t recognize 0100100100101 0100100100101
0101010101101
0101010101101
changes to the primary 0101010010100 Data 0101010010100
100010010
data copy (e.g. via 100010010 Coherency
SnapRestore®) will cause
data corruption issues
• When does the cache invalidate data?
Key criteria
include • Is the cache a write-through or a write back cache?
• Does the cache retain data across a reboot etc?

18. Flash Accel: Snapshot Coherency
Storage Operation Flash Accel Operation
Take snapshot • Store metadata of cache state at point-
in-time along with snapshot in ONTAP
Restore snapshot • Read metadata stored with snapshot
• Offline - Unmount • Compare snapshot state metadata with
device and current cache state metadata
disconnect from VM • Invalidate changed blocks between the
• Online – via two states and rollback cache to
SnapDrive snapshot state
