Data Placement Challenge Primary Storage Pool: All data – hot and cold Objective: Intelligently place “hot” data on the highest performing media “Hot” Data 10-20% Data should be fast when hot, and low cost when it’s cold
Virtual Desktop Workloads Are Extreme Storage IOPS can spike 3-5x
Virtual Storage Tier and Flash Cache • Flash Cache and SATA • Automatically promotes hot data to Flash • Reduced costs and spindle count • Flash absorbs high performance IOPS Entire Data Set Flash Cache SATA
Virtual Storage Tiering (VST) in Action… • Server Cache (e.g. Flash Accel) • Server flash offloads IOPS • Data ONTAP manages data • Operational simplicity • Optimal $/IOPS & $/GB Flash on the Server ServerLevel SSD on the Server Flash-based caching storage acceleration ControllerLevel Flash Cache SSD: Fastest, $$$$$ Flash Pool DiskLevel FC/SAS: Small, Fast, $$$ SATA: Big, Slow, cheap

Key criteria include 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
Benefits of Adding Flash Accel to Storage Cache - Preliminary FAS + Flash Accel FAS Only FAS + Storage Cache FAS +Storage Cache + Flash Accel 1.0x 1.3x 1.9x 2.2x • Adding Flash Accel enables a much greater IO level without increasing latency • Setup – FAS3270 with SATA Drives, Micron P320 PCI-e card on ESX host
Flash Pool Overview Flash Pool delivers the ability to add an SSD cache to an existing HDD aggregate which provides • Offload of expensive HDD operations into the SSD cache to balance peaks in workloads • Persistentcache across failover events allows the SSD cache to be immediately available (no rewarming) • Reduce HDD spindle count while achieving the same performance at a lower total configuration cost
Flash Pool Overview Flash Pool does not … • Accelerate write operations – Data ONTAP is already write optimized! • Reduce or alleviate high CPU or memory utilization • Cache sequential (read or write) or large block write (>16kB) operations • Increase maximum IOPS or throughput limits for a system
Data ONTAP Requirements Software requirements • Clustered Data ONTAP 8.1.1 or Data ONTAP 8.1.1 operating in 7-Mode • HDD based 64-bit aggregate • Aggregate state must be healthy (can’t be FAILED, LIMBO, offline or in a foreign state) • Can be a RAID-DP, RAID 4 or SyncMirror aggregate • Root aggregate support requires PVR (8.1.1 only) • No license is required – it’s free!
Platform Support Requirements Supported platforms • Entry-level: • FAS2220, FAS2240-2 and FAS2240-4 • Midrange: • FAS/V3160, FAS/V3170, FAS/V3240, and FAS/V3270 • High-end: • FAS/V6030, FAS/V6040, FAS/V6070, FAS/V6080, FAS/V6210, FAS/V6240, and FAS/V6280
Configuration • Creating a Flash Pool • The HDD 64-bit aggregate must already exist • Two-step process: • Set the aggregate option for Flash Pool • 7-Mode: aggr options <aggr_name> hybrid_enabled on • Cluster-Mode: storage aggregate modify -aggregate <aggr_name> -hybrid-enabled true • Add SSDs into a new RAID group • SSDs RAID groups cannot be removed once added (you must destroy the aggregate to repurpose the drives)
Flash Cache, Flash Pool or Both? Flash Pool Flash Cache PCIe SSD HDD System Level Cache Aggregate Level Cache Caches reads for all (non-flash) volumes Caches reads and random overwrites Per volume cache policies Does not count towards spindle limits Persistence across planned and unplanned failover events Plug and play deployment and administration
NetApp Flash Cache Optimize Performance and Reduce Costs • Flash Cache improves average latency for random reads • Increase I/O throughput of disk-bound storage systems without adding more disk drives • Reduce costs by using fewer, larger disk drives • Effective for file services, databases, messaging, and virtual infrastructure • Predict your results before buying for an existing storage system
