Compellent’s SSD Overview ƒ ONLY SAN solution with block-level intelligence ƒ Specifications • 146 GB capacity • 4Gb Fibre Channel interface • STEC Zeus IOPS™ ƒ Storage Center Requirements • Storage Center 4.5 or greater • 4Gb SBOD Enclosure – FW 08.08 or greater • 4Gb front end connection Compellent Confidential, 5 The Need for Solid State Storage * Courtesy of ESG – “The State of Solid State” March 2009 Compellent Confidential, 6 Spinning Media is Not Keeping Up ƒ Applications continue to demand more performance ƒ Hard drives have peaked at 15K RPM ƒ Hard drive latency is limited to that of an individual drive *Courtesy of Intel ƒ Increasing spindle count for IO performance may result in unused capacity “Solid-State disks that replace hard disks are the easiest way of adding solid-state storage to an existing array.” – Storage Magazine July 2008 Compellent Confidential, 7 FLASH Pricing Continues to Decline ƒ NAND FLASH pricing expected to decline faster than HDD ƒ Expecting 50-70% FLASH component price decline year-over-year ƒ Rapid adoption of SSD technology expected Compellent Confidential, 8 All FLASH is Not the Same Enterprise Drive Consumer Drive Compellent Confidential, 9 Drive Level Comparison FC SSD FC HDD SATA HDD Tier 0 Tier 1 or 2 Tier 3 146 GB 450 GB 1 TB Access Times / Latency 20-120 µs 2 ms 4 ms MTBF (hours) 1.6 million 1.6 million 1.2 million 220 MB/s – read 115 MB – write 170 MB/s – read 110 MB/s – write 100 MB/s – read 100 MB/s – write Best Better Good 8 Watts 16 watts 11 watts Applications Capacities Sustained Data Rates Vibration Tolerance Power Consumption Compellent Confidential, 10 Solid State Storage Implementation Options FLASH CACHE RAM HDD (3.5”/2.5”) HBA Controller <$30K < $5K >$100K DB acceleration OLTP financial analysis Web 2.0 DB acceleration OLTP financial analysis Web 2.0 DB acceleration OLTP financial analysis Web 2.0 Management Storage Array Server RAM Controller IOPS Performance 30,000-50,000 80,000+ 600,000+ Form Factor Unit Price Targeted Applications Compellent Confidential, 11 Enterprise vs. Consumer Flash SSD Enterprise Flash SSD ƒ Single-level cell (SLC) Consumer Flash SSD ƒ Multi-level cell (MLC) Stores one bit per cell Stores multiple bits per cell ƒ Higher cell endurance ƒ Lower cell endurance 100,000+ writes 10,000+ writes ƒ Dual-ported interface ƒ Commercial interface FC, SAS USB, FireWire, SATA ƒ Wear-leveling algorithms ƒ Only remaps bad blocks ƒ Multi-channel parallel IO ƒ Optimized for reads ƒ Designed for 24x7x365 ƒ Designed for 9x5 Compellent Confidential, 12 SSD RAID Comparison RAID Minimum Configuration Automated Tiered Storage Compellent Others 10 5 3 Drives 6 Drives (2 + 1 hot spare) (5 + 1 hot spare) Yes No Compellent Confidential, 13 Data Progression ƒ Reduced cost of storage (CAPEX) –Buy less storage –Leverage lower cost storage when required ƒ Reduced operational costs (OPEX) –Fewer FTE resources for administration ƒ Reduced downtime through additional recovery points –Integration with Data Instant Replay ƒ Business Partner differentiation –Unique value proposition is highly differentiated Compellent Confidential, 14 Cost = 1/10 Differences in Tiered Storage Traditional Compellent Tier 1 Tier 2 Problem: Storage Tiers Solution: Data Progression • Some vendors support ability to move volumes between tiers • Different drive types supported • Automated data classification and movement is bi-directional • Replays are automatically placed on Tier 3, typically at least 20% the cost • Allows creation of 5 times more recovery points • Do not provide automated data movement • Requires third party software for classification and movement • Snapshots must be stored on same disk type as volume Compellent Confidential, 15 Data Progression Mechanics ƒ Metadata accurately determines ideal data placement ƒ Intelligent movement between tiers based on frequency of access ƒ Volumes and files are stored across technology and RAID levels based on performance and redundancy attributes ƒ Enable migration for a complete volume for specific periods of time Compellent Confidential, 16 Compellent Differentiators ƒ Leverage Data Progression to minimize customer CAPEX and utilize SSD for most active data ƒ Through Dynamic Block Architecture (DBA) have the ability to put a portion of a volume on SSD ƒ Thin Provisioning supported for all drive types – SSD, Fibre Channel and SATA ƒ Investment protection – use existing SBOD enclosure Compellent Confidential, 17 Competitive Analysis Feature Competitor Compellent Compellent Difference Drive Type STEC ZeusIOPS™ STEC Zeus IOPS™ None Disk Enclosure Unique enclosure required for SSDs; existing customers must upgrade Uses existing fibre channel 4Gb enclosure Ability to use existing enclosures – $3K-$5K savings Min # of SSDs 6 (5 for RAID 5 + hot spare) 3 (2 for RAID10 + hot spare) 50% savings Data Progression Volumes only support one drive type (e.g. SSD) Automatic Data Progression 80% savings Volumes do not support “Thin Provisioning” Dynamic Capacity is supported regardless of drive type 50% savings Data Growth Compellent Confidential, 18 SSD Performance ƒ Exchange DB example – 30 hard drives replaced by 1 SSD – Read and Write latency went down by over 50% – Power Savings = 98% – Drive Savings = 33% Compellent Confidential, 19 SSD Candidates ƒ All vertical markets ƒ Applications –Defense –E-commerce –Entertainment –Financial Services –Telecommunications –Database Storage –Online Transaction Processing –Data warehousing –Web File Sharing –Identifying Hot Files Data Patterns Tend to be… High Writes, Random Small Block High Reads, Random Small Block High Writes, Sequential, Single Threaded Small Block High Reads quickly follow writes Small Block High Writes, Sequential Large Block High Reads, Sequential Large Block Compellent Confidential, 20 HDD Flash Audience Response Requested Q: Compellent’s SSD solution leverages which of the following features?

Solid State Disks provide the lowest latency, dramatically improving performance for applications requiring next-to-zero latency. Are you looking to improve the overall reliability of your storage environment? Because Solid State Disks do not contain any moving parts, their reliability exceeds that of spinning media. Has your datacenter ran out of power and/or rack space for storage equipment? Solid State Disks require ½ of the power that an equivalent rotating media hard drive (e.g. 8 watts for SSD vs. 16 watts for 15K fibre channel drive).
