Changing the Economics of Storage: Flash at the Price of Disk

• Data that is highly valuable to the business and can be used for deriving business intelligence, financial analysis, etc.
• Read and write percentages• Transfer sizes• Sustained vs. bursty I/O patterns
• Data accessed frequently vs. cold, rarely accessed data
• Heavily read vs heavily written data• Data optimized for tiering vs caching

Business value
• Hot data that needs to be retrieved extremely fast without latency
• IOPS vs. throughput
What characterizes your workloads?Traditional “one size fits all” data storage strategy is inefficient
Each type of data needs to be treated differently to align the application performance with capacity and cost requirements

New form factors: PCIe cards, appliances, shared storage
Virtualization is increasing the demand for random I/O with the “mixer effect”
Flash prices falling faster than HDDs but still considerably higher than 15K HDDs
Multi-core processors drive up processor utilization and demand for more I/O per server
Flash adoption is acceleratingPent-up demand for improving application performance at the right price point

Flash storage can be deployed at various layers to accelerate application performance
Server-based cache (Tier-0)• Flash drives placed directly on high speed PCI bus
in application servers • Caching software enables server to leverage
flash storage as an extension of memory cache
SSD tiering in shared storage • A few SSDs can be added to the array to
dramatically increase performance for targeted workloads
OR• An entire storage tier can be deployed on SSDs
so that complete volumes and datasets can be fit in flash
COMING SOON: Fluid Cache for SAN• Benefits of Fluid Cache extended to the entire
SAN for maximum performance and reliability

Indexing• Maintains indexes to
allow quicker access to data
• Runs on databases to accelerate locating a block of data in queries
Data Warehousing• Stored data used to
create reports or derive Business Intelligence
• Used for data mining, analysis, hypothesis testing, modeling
OLTP• Manage transaction-
oriented applications, i.e. retail, banking
• Business can be hurt if data not accessible,slow
• During peak usage, customer experience can be effected
VDI• Hosting desktop OS
within a VM on a centralized server
• Facilitate a quick retrieval of gold images
• Boot storms, write allocations and latency are issues

Secret sauce behind the flash optimized Compellent: tiering with Data progression
Flash-optimized Data Progression leverages the endurance of write-intensive SSDs and the value of read-intensive SSDs.
Advanced software tiering seamlessly manages data• Incoming writes are written to the write intensive SSDs for fast access
• Read intensive data is automatically moved to less expensive read optimized SSDs keeping Tier 1 free for new incoming writes
• Cold and non-performance data is migrated to lower tier, less expensive rotating disk
