#1 – Configuration & price flexibility OLTP and Data Warehouse Have Different Design Needs IBM believes that designing and building systems optimized for specific workloads is the best approach OLTP Systems – Run the business by processing the transactions that are critical to the organization – Utilization is driven by the number of users, not complexity of SQL – Smaller block I/O – 8K – Higher write - updated online, many index lookups Would you – Buffer, log and cache management are key to performance in clusters configure OLTP and
#1 – Configuration & price flexibility Exadata — Rigid and Lacks Customization to Client’s Workload You’re locked in to a fixed configuration that lacks the granularity to size YOUR workload to YOUR needs — Fixed node sizes, fixed ratio of cores-to-disks and fixed upgrade options Processing and storage capacity are not sold independently — when you need to increase processing, you likely don’t need more storage – Typical Exadata system running OLTP can end up with 6x-28x more storage than required – When you need high-performance, you are paying too much for 100 TB of usable low- performance storage you may never use Exadata storage nodes come with 5 TB of expensive flash cache and 100 TB of disk storage — whether both are required or not If you have a ¼ rack and you want to upgrade, you have to move to a ½ rack – Doubling the size of your environment — even if you only need one more processor – Have to pay Oracle license and maintenance fees — even if you’re not using all that processing power
#1 – Configuration & price flexibility POWER7 Systems Flexibility Advantage with Oracle Database Implement and deploy an appropriate mix of RAC and non-RAC Oracle database instances as well as application instances Size individual database LPARs to match Isolate critical databases in different LPARs specific CPU, I/O and memory needs Isolate database by department or other Scale from very small to very large LPARs Mix test and production on the same frame and Oracle instances Mix application and database on the same Create independent security domains machine Deploy varying versions of Oracle AIX OS OS OS OS OS OS OS WPARs
#2 – Storage Technology Exadata — Lacks Key Storage Technology and Options Support Feature IBM Storage Exadata Storage choices YES, provides many choices with flexible cost and NO, only option is very expensive/GB. Paying for very and warranty warranty options — all support Oracle and Oracle RAC expensive Flash Cache that most applications don’t need options Storage can be repurposed for other applications/needs Exadata storage is only supported with Exadata Scalability Do not need a fixed ratio of CPU cores to disks Need a fixed ratio of CPU cores to disk Can size your workload to what you need Same ratio for OLTP and Data Warehouse, and whether using compressed data or not Reliability POWER7 with RAID-6 has a far more reliable scheme for Exadata standard configuration uses less reliable data redundancy than Oracle Exadata standard mirroring scheme (ASM) configuration with mirroring
Capacity efficiency POWER7 Systems and the DS3500 have 1/3 higher With Exadata’s standard configuration, it operates at 50% capacity efficiency than Oracle Exadata. IBM operates at capacity efficiency 67% capacity efficiency. With IBM, less capacity is With Exadata’s optional triple mirroring, reliability is devoted to the overhead necessary to keep the data safe improved, but capacity efficiency drops from 50% to 33% Compared to Exadata’s optional triple mirroring, IBM has
#4 – Scalability Scale Up or Scale Out Depending on Application Needs with POWER7 With Exadata, you Drive a consolidation strategy and add in pieces you need, have to add as you need them capacity in big – Add additional CPUs for better performance increments and – Add additional memory for cache-sensitive workloads only via scale-out – Add SSD for reduced I/O latency nodes, which – increases Leverage existing disks for tiered storage complexity and Scale up and configure fewer, more powerful servers management – considerations. Fewer moving parts means less to manage
#5 – Reliability Power Systems with AIX Deliver 99.997% Up Time Power Systems with AIX deliver excellent reliability, availability and serviceability Availability – The least amount of downtime Minutes of downtime per year – 15 minutes per year – 2.3 times better than the closest competitor 180 – More than 10 times better than Windows
120 Reliability – The fewest unscheduled outages – 60 Less than one outage per year
#7 & 8 – OS Flexibility & Software POWER7 Provides OS Choice and Software Simplicity Provides choice of proven operating systems – AIX IBM POWER7 – IBM i Systems offer a – choice of proven Red Hat and SUSE Linux operating
systems and Supports available Oracle versions up through 11gR2 allow you to – No forced migrations leverage your existing Oracle Allows mixing of applications and database on the Database Server same machine investment!
#9 – Roadmap IBM Power Technology — Dependable Execution For a Decade
Exadata V1 was retired after one year with no upgrade path to Exadata V2. V2 was introduced on a completely POWER8 different hardware POWER7 platform! Oops! 45 nm POWER6 Proven 65 nm technology POWER5 Dual Core and clear On-Chip eDRAM 130 nm Power-Optimized Cores roadmap What will the POWER4 Dual Core Memory Subsystem ++ High Frequencies SMT++ next version of 180 nm Virtualization + Reliability +
