2 AGENDA 01 Wer steht bei meinem Server auf der Bremse? 02 IBM Flashsystem 03 automatisches Tiering Einsatzbeispiele Diskussion

4 Wer bremst meinen Server? Disk-Based I/O Time Network Time CPU Time FlashSystem I/O Time Network Time CPU Time Time Recovered 1 microsecond : 1 second :: 1 second : 11.5 days

5 System-Performance Entwicklung CPU performance up 10x this last decade Storage has grown capacity but unable to keep up in performance Systems are now Latency & IO bound resulting in significant performance gap 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 **

6 Taktik zum Schliessen von Performance-Engpässen Most Costly & Volatile Add More Memory HDD Performance Enhancement Wasteful, Expensive & Ineffective with Storage Latency Issues Typical Performance Mitigation Tactics Expensive & Ineffective for Storage Performance Issues Add CPUs Tune & Modify Application Time Consuming, Very Expensive & Risky

9 IBM Flashsystem Waiting for the 25k rpm Disk? CPU, Network, SAN, Memory and Bus are getting faster Micro Latency: High Scalability: Low TCO: Do things faster Do more things concurrently Save money and boost value Flash delivers performance and value to boost the applications running your business.

10 Comprehensive FLASH Offerings IBM FlashSystem addresses the two primary segmentations of the flash market as defined by IDC taxonomy: Absolute Performance for extreme performance of throughput, IO, and latency. Enterprise for full featured enterprise features sets married to flash performance IBM FlashSystem IBM Software Defined Flash Solutions Standalone all flash array Also a building block Eschew features that increase latency, bottleneck IOPS or cap bandwidth Promote use of application-level services Software defined storage FlashSystem as a storage enclosure Promote use of SAN services

11 IBM Flashsystem 840 Data center optimized to deliver extreme performance, flexible capacity and total system protection Capacity Options Flash module configuration Performance at-a-glance Minimum latency Write 90 µs Read 135 µs Maximum IOPS 4 KB Read (100%, random) 1,100,000 Read/write (70%/30%, random) 775,000 Write (100%, random) 600,000 Maximum bandwidth 256 KB Read (100%, sequential) 8 GB/s Write (100%, sequential) 4 GB/s 2 x 2 TB 4 x 2 TB 4 x 4 TB 8 x 2 TB 12 x 2 TB 8 x 4 TB 12 x 4 TB Raw capacity 5 TB 11 TB 21 TB 21 TB 32 TB 42 TB 65 TB RAID 0 usable capacity 4 TB 8 TB N/A 16 TB 24 TB 32 TB 48 TB RAID 5 usable capacity N/A 4TB 8 TB 12 TB 20 TB 24 TB 40 TB

13 IBM VARIABLE STRIPE RAID (VSR) No Parity Parity Parity Form Factor SSD Flash failure = Disk failure Requires top-level RAID Relatively frequent hot-swaps Enterprise Flash Drive or Memory Module Flash failure = Degraded state within module Performance impact on RAID set Hot-swap to resolve FlashSystem with Variable Stripe RAID Preserves Flash life Preserves performance Re-parity data in microseconds Value of Variable Stripe RAID TM Less maintenance touches while still preserving the life, protection, and performance of the Day-1 experience

14 IBM VARIABLE STRIPE RAID (VSR) 4k 4k 4k 4k 4k 4k 4k 4k 4k 4k Gateway Interface Flash Controller Patented Variable Stripe RAID allows RAID stripe sizes to vary If one die fails in a ten-chip stripe, only the failed die is bypassed, then data is restriped across the remaining nine chips VSR reduces maintenance intervals caused by flash failures

15 TWO-DIMENSIONAL RAID IBM Variable Stripe RAID is 1st level of protection (module-level) System-level RAID protects against flash controller failure (abrupt module failure) Canister-1 FC-1 FC-2 MC-1 MC-2 Canister-2 FC-3 FC-4 RAID-5 across modules, hot swappable from front of chassis XBAR 0 Two independent crossbar (XBAR) controllers Interface controllers stripe across XBARs Granular capacities configurable with 2, 4, 8 or 12 flash modules

16 Data Center Optimized

17 IBM Flashsystem 840 Built-in Encryption Protecting business s most valuable asset Industry standard AES-XTS 256 required by most leading compliance regulations such as HIPAA and FIPS Data-at-rest design Local key management

18 Flashsystem 840 Management Modern design Icon-based navigation, informative graphics, and visualizations Reduce complexity Improve efficiency and productivity Unified, cross-platform design

21 IBM Easy Tier: Automated Storage Tiering Less Active Data Migrates Down SSD Arrays Active Data Migrates Up Constantly analyzes I/O and migrates data to optimize performance Set it and forget it unlike competitive tiering offerings HDD Arrays Improve performance up to 3x using as little as 5% solid-state storage

23 SVC CASE STUDY: TRANSPORTATION IBM DS5100 Fuijitsu Eternus DX90 S2 EMC CX4-120 SVC Cluster RamSan 630 IBM FlashSystem 810 IBM SAN384B SAN Directors HDS AMS we can easily move whole systems or databases from traditional storage to flash storage at the push of a button. This capability has increased our agility and enables us to improve the user experience and react quickly to changing performance requirements. Roland Wagner, Team Lead Systems and Operations at SSB Challenge Needed to run the public transportation business and supporting external client operations while maintaining a low cost Solution Using SVC Easy Tier, SSB deployed 2 FlashSystem 810 and 2 RamSan 630 products to accelerate overall infrastructure Placed critical SAP e-business applications requiring consistent high performance onto FlashSystem to drastically improve processes Benefit TCO was 50% less than previous solution Critical application was improved from 2.5 hours to 6 minutes of processing time Backup error correction process went from 2 days to 8 hours

24 SVC CASE STUDY: INDUSTRIAL CLIENT Challenge SAP performance problems $100K/month SLA penalties - application was too slow Concern of future scalability of existing solutions Solution Deployed 2 FlashSystem 810 products to accelerate critical end of month SAP e-business process Benefit 464% better response time than pure disk solution 157% better CPU utilization = lower Oracle license costs 75% lower operational costs 2-4x overall performance improvement for critical month-end batch process

25 ACCELERATING SAP CASE STUDY: CEGEKA FlashSystem 820 SVC Servers Switch XIV Challenge Cegeka is a leading Belgium IT company with a broad portfolio of services. As their MSP division continues to grow, the new SAP customers are requiring higher SLAs. Solution Deployed IBM FlashSystem 820 into their SAN with IBM SVC Placed critical SAP e-business applications requiring consistent high performance onto FlashSystem to drastically improve processes Benefit Improved SAP jobs by 10X 3X improvement for end user response times 10-20X lower power consumption compared to alternative HDD solutions Because of it s size, it is much easier and far faster to deploy and that s why it s a very interesting investment in terms of TCO and return on investment. The added value of the IBM FlashSystem that we brought to a high-end repeat customer is tremendous from a technical as well as from a financial point of view.
