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

2Solutions Road Show 2014

March 2014 | India

• 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

Performance

Access patterns and frequency

I/O patterns

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


March 2014 | India

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

SSDs have different characteristicsCompellent is the first storage solution to tier sub-LUN data across SSDs

Tiering flash across multiple SSD types enables Compellent to disrupt the flash cost model with a superior $/GB ratio.

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
