  3. What is Flash? Consumer grade flash memory (MLC) is used to store data in everyday electronics:

  4. Storage Latencies DRAM X3850 X6 DDR3 Flash 5 µs IBM FlashSystem 100 µseconds 2.5” SSD (on the SAN) ex: (Novotel – Mr. Bricolage 5min) 1-3 milliseconds SAN Disk ex: (Flight: Sofia – Varna 45min) Tape 3-10 milliseconds ex: (Flight: Sofia – London 4h30min) Slow

  5. Latency Translates to Application Efficiency Servers, Applications and Databases are FASTER! Time Waiting for I/0 (Waiting for Array) Time Processing Data (Server CPU) CPU Utilization & App. Efficiency 4% Total Application Processing Time 5,200us (5.2ms) 5,000us (5ms) 200us (.2ms) CPU Utilization & App. Efficiency 50% Total Application Processing Time 400us (.4ms) 200us (.2ms) 200us (.2ms) Benefits & economics outweigh disk No application Or architecture Changes What do you do with the Extra Time? Reduce floor space, power & cooling IBM FlashSystem Disk/Hybrid/SSD

  6. Flash Reality • Clients will buy flash – sooner or later • Minimal application changes needed – non-disruptive • Can co-exist with any other storage vendors – no holy wars with IT • Flash could be quick and easy to deploy – various methods of deployment • Flash has a quick ROI – at least 3X storage performance improvement • Flash Solves Business Problems – TODAY Performance Gap From 1980 to 2010, CPU performance has grown 60% per year* …and yet, disk performance has grown ~5% per year during that same period**

  22. IBM FlashSystem 840 • 2U - Purpose-built/FPGA – eMLC 24nm flash chips • Granular Capacities: 2TB and 4TB modules • 4, 8, 12, 16, 20, 24, 32, 40, 48 • NEW GUI • Encryption • Optional, licensable feature • AES-XTS 256-bit data-at-rest • Local management • Module-level implementation (Self-Encrypted Flash Controller) • Zero impact on performance • IMPROVED RAS features: ALL hot swappable components: - Flash modules, power supplies, batteries, interfaces, fans • Concurrent code load • Encryption • Low latency - 135/90 µs R/W parallel design • CPU efficiency and productivity: 625 watts • 1.1M IOPS • 8 GB/s bandwidth • Multiple connectivity interfaces • 16Gb/8Gb Fibre Channel • 40Gb QDR InfiniBand • 10Gb FCoE

  25. IBM FlashSystem 840: Flash Module, Logical View Scalability and Parallelism: 7,680 parallel flash operations and 1,600 DMA parallel operations FPGA FPGA for a second: In most hybrid or SSD-based solutions, most of these actions are done in SW-heavy layers that ultimately impact LATENCY. FPGA FPGA FPGA Primary Board (2TB) Secondary Board (2TB) - Optional FPGA FPGA Flash Controller - FPGA2 or 4 per Module Data path, Hardware I/O logic Look up Tables and Write Buffer Each controls 20 flash Chips Gateway Interface FPGA I/O interface and Direct Memory Access path Control PPC and DRAM Out of Data path operations Garbage collection, Error Handling, System Health Wear Leveling, Statistics, etc. Flash Chips 20 per Flash Controller 40 or 80 per Module Data XOR parity

  26. IBM FlashSystem 840: Reliability Ingredients Superior Durability: Using the Best Flash Superior Protection: Beyond Disk RAID Chip/Plane/Die level protection • SLC Market demand decreasing. • eMLC data protection techniques delivering more wear life than what market demands • eMLC delivers best Price/Performance Variable Stripe Sizes Read Disturb Mitigation Automatic Read Sweeper High-Speed Clock Recovery Advanced Engineering = Less Maintenance 3X 10X Protection Within And Across Flash Modules Self-Recovering Flash Modules Avoid system rebuilds

  27. Flash Quality Matters! • Flash type matters • P/E cycles vary • MLC: Multilevel cell flash is consumer-grade • eMLC: Enterprise-grade MLC • 10x improvement over MLC • SLC: Single-level cell • 33x improvement over MLC • eMLCwill handle most enterprise applications workload requirements • FlashSystemtechnologies like Variable Stripe RAID™ and 2D Flash RAIDTM, wear leveling and over-provisioning lengthen system life by improving endurance of both eMLC and SLC

  28. Flash Quality and Endurance (Technical) • Writes will always be sequential • Via “wear leveling” • Total Flash Capacity = 1 Full Write Cycle • 1st P/E Cycle would start on 2nd Write Cycle • Flash quality is driven by the chip type • MLC, eMLC and SLC • Flash Quality = 3K, 30K or 100K respectively • Media Write Bandwidth • How much data will written per second • This is driven by the application • Is NOT going to change! • How to increase endurance? • 1. Increase capacity • 2. Increase quality of chip • eMLC is 10x the capacity of cMLC

  29. Flash Quality and Endurance (Technical) cont. Let’s assume a 720, 820 and other MLC arrays • Use a reference 1GB/s Sustained BW • 720 (SLC), 5TB = 15.85 Years • 820 (eMLC), 10TB = 9.51 Years • Both at same $ cost of capacity • OTHER Arrays (cMLC) • 1 Year at 1GB/s before degradation • Sustained Writes don’t help cMLC • Will require a lot more capacity to increase endurance levels
