Where’s your pain?How long can you manage data the same way?

Volume

Page pool

Fluid Data Architecture• Fluid Data Architecture – the Page Pool

– Collection of allocated and unallocated disk blocks

– Maps pages to volumes

– Maintains metadata

– Default page size is 2MB (options: 512KB, 4MB)

• Automated, Sophisticated Block Management– Change RAID levels by re-pointing pages

– System manages data mapping across multiple RAID levels

– Individual files can span multiple drive types and RAID levels

• Page Pool grows/shrinks as needed– Self defragmentation and tuning

Data Progression• Performance Optimization

– Fluid Data Architecture provides metadata management

– Data Progression analyzes metadata and provides sophisticated data movement

– Fast Track reserves outer tracks for increased performance

• Benefits

– Shrink overall drive counts without sacrificing performance

– Reduce the need for costly, high-power drives

“Write Layer” plus Auto-TieringAlways performance optimized, always cost-optimized

Write Layer

Fast Track overview• Disk drives are physical devices that are

the slowest part of a storage system

• Reducing physical delays (rotational + seek time) provides significant performance gains

Rotational Latency

Fastest tracks

Utilization – Dynamic Capacity

Thin Provisioning Benefits

• No pre-allocation required

• Snapshots are thin provisioned

• “Thin” data migrations

• Free space is automatically recovered

• No limits on application usage

• Ideal for multiple tiers of SSD

– Read intensive data is automatically moved to read optimized SSDs (MLC)– Write intensive data stays on high endurance SSDs (SLC)– This is automatically handled by the Compellent OS– Cold data moved to 7200 RPM Discs

Continuous Snapshots – Data Instant Replay

• Replay-Based Architecture Benefits

• Patented continuous data availability

DID YOU KNOW?

There are no limits

to the number of

snapshots.

• Space efficient – freeze pointers

• No space pre-allocation

• Replays automatically move down to lower cost disk

• Delete any one, keep any one

• Integration with common applications

• Ideal for test/dev, VMs, Boot from SAN, Consistency Groups

Data Instant Replay - Ease of Use

• Outlook style scheduling

– Intuitive interface

– Zero startup time

– No scripting required

– Replay templates can be used with any volume

• Set frequency / expiration date

– Frequent replays create granular recovery intervals

– Expiration interval prolongs replay availability

• Automated Replay management

•Previous replays are coalesced to reduce storage space

Remote Instant Replay

• Replicate Thin to SaveDID YOU KNOW?

68% of Compellent

customers replicate

their data to another

site.

Warsaw

London

Las Vegas

• Volumes are thin, replication is thin

• Significant reduction in cost of bandwidth and management

• Only replicate changed blocks of data (no duplication)

• Set up replication in 6 clicks

• No space pre-allocation

• One button, automated restore

• DR Testing – without downtime

Remote Data Instant Replay

• Unlimited replications

• Synchronous/Asynchronous

• Synchronous HA/HC

• Tight integration with Dynamic Capacity and Data Instant Replay

• Mount target volumes without stopping replication

• 1:1, Bi-directional, Multi-site, Multi-hop

• Centrally managed by Enterprise Manager

• One-click restore (reverse replication)

• Recoveries are read/write by default

• Includes consistency groups

Live Volume

• Dynamic Business Continuity DID YOU KNOW?

There is no limit to the

number of Live

Volumes that can be

created, deleted or

updated.

• Acts as a storage hypervisor, actively presents storage from two arrays at the same time

• Architect a grid of shared storage and manage as one

• Deliver storage agility, continuous data access and high availability

• Storage follows VM movement

• Fully integrated, no appliances or server agents
