Exadata Uniquely Accelerates Analytics

• Exadata automatically offloads data intensive SQL operations to storage– Unique Smart Scan technology offloads SQL processing to storage delivering:• Over 350 GB per sec SQL scan throughput while offloading database CPUs

– Unique algorithms offload Data Mining, Decryption, Aggregation, and Backups to storage

• Exadata automatically reduces I/O– Unique Database-aware Flash Caching gives speed of PCI Flash with capacity of disk–Unique Storage Indexes eliminates I/O that is not relevant to a particular query

• Exadata uses analytics optimized Columnar format– Unique Hybrid Columnar Compression reduces space usage by up to order of magnitude– Unique Columnar Flash Cache automatically transforms data to column formats

Exadata Uniquely Accelerates OLTP

• Exadata automatically eliminates traditional OLTP bottleneck: Random I/O– Unique scale-out storage, ultra-fast NVMe Flash, ultra-fast iDB on InfiniBand delivers:• Over 5.4 Million Database 8K reads or writes per rack; ¼ millisecond I/O latency at 2M IOPs

– Unique Smart Flash Logging automatically optimizes OLTP logging to flash

• Exadata automatically eliminates OLTP stalls from failed or sick components– Unique detection of server failures without a long timeout avoids system hangs

– Unique sub-second redirection of IOs around sick devices avoid database hangs

• Exadata automatically eliminates inter-node coordination bottlenecks–Unique Direct-to-Wire Protocol gives 3x faster inter-node OLTP messaging

– Unique Smart Fusion Block Transfer eliminates log write on inter-node block move

– Unique RDMA protocol to coordinate transactions between nodes

Exadata Uniquely Optimizes Mixed Workloads and Consolidation

• Exadata automatically prioritizes latency sensitive operations– Unique prioritization of critical network messages for locks, cache fusion, logging, etc.– Unique prioritization of OLTP I/O over Analytic or Batch I/O

• Exadata automatically prioritizes important workloads based on user policies– Unique prioritization of CPU and I/O by job, user, service, pdb, session, SQL

• Exadata automatically provides isolation between multiple tenants – Unique no-overhead virtual machines– Unique prioritization and separation by database, or pluggable database

11

•Many lanes• Priority Lane•Reserved Lane• Separate Road



Exadata Automates Software Updates at Cloud Scale

• Automation updates all Exadata infrastructure software on full fleet– 600+ components per full rack

• Updates multiple systems in parallel

• Runs automatically on schedule– Online (rolling) or Offline (all in parallel)

• Pull Model simplifies orchestration– Just point Exadata system at software

repository and give update window– Dependencies between systems

automatically handled

Exadata Uniquely Achieves Memory Speed with Shared Flash

• Architecturally, Storage Arrays can share Flash capacity but not Flash performance due to network bottlenecks– Even with next gen scale-out, PCIe networks, or NVMe over fabric– Network continues to be a huge bottleneck

• Must move compute to data to achieve full Flash potential– Requires owning full stack; can’t be solved in storage alone

• Exadata X7 delivers 350 GB/s Flash bandwidth to any server– Approaches 800 GB/s aggregate DRAM bandwidth of DB servers

Oracle DB In-Memory Delivers Best Analytics AND Best OLTP

• Analytics & reporting run 100x faster using in-memory Column format• Optimized for vector processing• Pure in-memory, so changes are fast

enabling mixed OLTP and analytics

• Table data kept in BOTH row and column format with full consistency

• OLTP uses proven Oracle row format

• No app changes, trivial to deploy• Full Scale-Out, Scale-Up, HA, etc.

Analytics: Exadata Brings In-Memory Analytics to Storage

In-Memory Columnar scans

In-FlashColumnar scans

• With Exadata Flash throughput approaching memory throughput, SQL bottleneck moves from I/O to CPU

• Exadata automatically transforms table data intoIn-Memory DB columnar formats in Exadata Flash cache– Enables fast vector processing for storage server queries

• Uniquely optimizes next generation Flash as memory– Now works for both row format OLTP databases, and

Hybrid Columnar Compressed Analytics databases

17


OLTP: Exadata Brings In-Memory OLTP to Storage

• Exadata Storage Servers add a memory cache in front of Flash memory– Similar to current Flash cache in front of disk

• Cache is additive with cache at Database Server– Only possible because of tight integration with DB

• 2.5x Lower latency for OLTP IO – 100 µsec

• Up to 21 TB of DRAM for OLTP acceleration with memory upgrade kit
