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
From 1980 to 2010, CPU performance has grown 60% per year
*…and yet, disk performance has grown ~5% per year during that same period

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

SVC CASE STUDY: TRANSPORTATION
“…. 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
SVC Cluster IBM SAN384B SAN Directors EMC CX4-120 Fuijitsu Eternus DX90 S2 HDS AMS 2100 IBM DS5100 IBM FlashSystem 810 RamSan 630
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
ACCELERATING SAP CASE STUDY: CEGEKA
“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. And this is why we decided to make it a standard offering in our private cloud services”
Luc Greefs, Director of Shared Technology and Infrastructure Delivery

Challenge
Energy Supplier in Denmark needed to host and implement a new billing solution, which had high IOPS requirements. The manufacturer of the solution required 144 direct attached drives in order to deliver the high IOPS requirement for a SQL DB - 2 TB.
Client was not happy to host a solution which were separated from clients current environment.
Solution
•2x IBM FlashSystem 820 (10 TB)
•Other IBM components included: SVC, and System x servers
•An IBM FlashSystem 820 behind SVC in each Data Center to speed up the performance of MS SQL
Benefit
•Speedup MS SQL application •Improved TCO and cost savings
•Kept energy consumption to a minimum •Sustained low Latency
•Happy users

A leading manufacturer of grinding, cut-off, sawing a drilling tools needed to convince their customers on the usage of a brand new product finding reference stories with similar workload.
Solution
•2x IBM FlashSystem 820 (2TB)
•Other IBM components include SVC, V7000, Flex System, Services
•FlashSystems are partitioned to be used as direct attached storage for log/database in a MS Exchange application and as hybrid storage behind the SVC •Other applications hosted on VMware can use
FlashSystem via SVC as tier1 storage or even as tier0 if required
