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

• 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

Columnar scans
• With Exadata Flash throughput approaching memory
throughput, SQL bottleneck moves from I/O to CPU
• Exadata automatically transforms table data into
In-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

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
