Exadata AI Storage: A New Era of AI-Powered Database Infrastructure

Mon, 06 Apr 2026 07:41:22 +0000

Oracle's Exadata platform has always been synonymous with extreme database performance. But with the release of Exadata System Software 24ai and 25ai, alongside the debut of Oracle Exadata X11M in January 2025, Oracle has taken a decisive step into the AI era. Exadata is no longer just a high-performance OLTP and analytics machine — it is now purpose-built to accelerate AI vector search, in-database machine learning, and mixed enterprise workloads, all on a single converged platform.

This post breaks down the key new features across software, infrastructure, high availability, monitoring, and security — and explains why they matter.

What Is Exadata AI Storage?

At its core, Exadata AI Storage refers to Oracle's strategy of pushing intelligence deeper into the storage layer. Rather than offloading AI computation to separate, purpose-built vector databases or GPUs, Oracle brings AI operations — particularly AI Vector Search — directly to the storage servers themselves. This means vector index builds, similarity searches, and distance calculations happen closer to where data lives, dramatically reducing the data movement that kills performance in distributed architectures.

The result? Key vector search operations running up to 30x faster with Exadata System Software 24ai, and further accelerated on X11M with in-memory vector index (HNSW) scans running up to 43% faster on database servers and up to 55% faster on storage servers compared to the previous generation.

Key New Software Features

1. AI Smart Scan

AI Smart Scan is an extension of Exadata's legendary Smart Scan technology, now purpose-built for AI workloads. It offloads compute-intensive AI Vector Search operations — including vector index builds and similarity queries — directly to Exadata's intelligent storage servers. This eliminates the need to ship raw data up to the database tier for processing.

Critically, AI Smart Scan enables thousands of concurrent AI vector searches in multi-user environments. This is a significant differentiator for enterprise RAG (Retrieval Augmented Generation) pipelines and AI applications that need to serve many users simultaneously, not just batch processes.

With the latest release (Exadata System Software 25ai / 25.1), Adaptive Top-K Filtering further extends this: each storage server maintains a running Top-K result set, reducing data returned to the database servers by up to 4.7x. Similarly, VECTOR_DISTANCE() calculations are now projected from storage, delivering up to 4.6x faster distance-based queries.

2. Exadata RDMA Memory (XRMEM)

XRMEM replaces the persistent memory (Intel Optane PMem) that earlier generations used, adapting to changes in the memory vendor landscape. It is built on DDR5 DRAM and accessed via RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), bypassing the OS, I/O, and network software stacks entirely.

The practical benefit: ultra-low read latency as low as 14 microseconds — a 21% improvement over prior generations — with scan throughput of up to 500 GB/s from XRMEM alone. Each Exadata X11M Extreme Flash Storage Server contains 1.25 TB of XRMEM, which sits as an acceleration tier in front of the Smart Flash Cache.

XRMEM is particularly impactful for OLTP workloads that require sub-20-microsecond response times, and it now also accelerates AI vector index reads transparently.

3. On-Storage Processing

This is the foundational principle that makes all the above possible. Exadata storage servers are not passive disk arrays — they are intelligent compute nodes in their own right. SQL filtering, column projection, decompression, encryption/decryption, bloom filters, and now AI vector operations all execute on the storage servers, not the database servers.

This dramatically reduces the volume of data sent over the internal network and processed by database-tier CPUs. For analytics workloads, this "push-down" processing model is why Exadata consistently delivers 10–100x better throughput than general-purpose storage.

4. In-Memory Columnar Speeds for JSON Queries

Exadata's In-Memory Columnar Cache on storage servers (also called Columnar Cache) stores a columnar representation of row-oriented data directly in flash cache. When queries access this data, they get the performance of columnar analytics without requiring data to be reformatted or migrated.

With Oracle Database 23ai — which is required to unlock the full Exadata Exascale feature set — JSON documents stored natively benefit from this columnar acceleration. Oracle Database 23ai's JSON Relational Duality views, which expose the same data as both JSON and relational tables simultaneously, can be queried at columnar memory speeds on Exadata, collapsing the performance gap between document and relational workloads.

5. Transparent Cross-Tier Scan

Exadata's multi-tier storage hierarchy — XRMEM → Smart Flash Cache → disk — is managed automatically and transparently. When a Smart Scan or AI Smart Scan runs, Exadata intelligently sources data from whichever tier contains it, combining reads from memory, flash, and disk in parallel.

This means administrators and developers never need to manually partition hot vs. cold data or tune tier placement. The system continuously tracks access patterns and moves data to the appropriate tier based on usage, keeping the hottest data in XRMEM and the next hottest in flash. The database never sees these tiers explicitly — it simply issues a SQL or vector query and receives results.

6. Caching Enhancements

Several caching improvements ship with the latest Exadata System Software releases:

Automatic KEEP Object Load into Exadata Flash Cache: Objects tagged with the KEEP storage clause in Oracle Database are automatically and proactively loaded into Exadata Smart Flash Cache — even before they are first accessed — ensuring zero cold-start latency for critical tables and indexes.
Write Back Flash Cache: Database block writes are cached in flash, eliminating disk I/O bottlenecks for large OLTP and batch workloads.
Cell-to-Cell Rebalance preserving XRMEM and Flash Cache: When data rebalances across storage servers (due to maintenance or failure), both the XRMEM and flash cache contents are also rebalanced, preserving performance levels rather than causing a cold-cache performance dip.

7. Columnar Smart Scan at Memory Speed

When Oracle Database In-Memory is enabled, Exadata automatically stores data in columnar format within Flash Cache and XRMEM if it will improve query performance. This brings columnar analytics performance — historically associated only with in-database memory (DRAM on database servers) — to storage-resident data, enabling analytics at memory speeds even when datasets exceed what fits in database-server DRAM.

A single Exadata X11M rack can deliver up to 100 GB/s of flash throughput and 500 GB/s from XRMEM for the hottest data, far exceeding what traditional storage arrays can achieve even with flash added.

8. Exadata Cache Observability

Exadata System Software 24.1 introduced ecstat (Exadata Storage Cache Statistics), a real-time utility that provides per-storage-server statistics on Smart Flash Cache usage, XRMEM hits, and I/O performance. This was a long-standing gap — DBAs previously had to rely on AWR snapshots to understand cache behavior.

In Exadata System Software 25.2, this was extended with CellSQLStat, which provides real-time, per-storage-server insights into active Smart Scan operations: CPU and memory usage, Storage Index and Columnar Cache I/O savings, flash and XRMEM hit rates, scan rates, and more. Both ecstat and CellSQLStat data are automatically included in ExaWatcher collections, making them available for historical analysis.

Infrastructure Improvements

Increased Number of Virtual Machines

With Exadata Exascale (the new intelligent storage architecture introduced in 2024 and available on X11M), the limit on Virtual Machine clusters per database server increases dramatically. Traditional Exadata with ASM supported 4, 8, or 12 VMs per database server. Exascale raises this ceiling to 50 VMs per database server, enabling far greater consolidation of Oracle Database workloads on a single Exadata system without sacrificing isolation or performance.

Exascale also centralizes VM storage in the shared Exascale storage pool rather than on individual database servers, increasing flexibility and simplifying management.

Secure Boot for KVM Virtual Machines

Exadata System Software now supports Secure Boot for KVM guest VMs, ensuring that only cryptographically signed and trusted OS images can boot on Exadata database servers. This closes a significant attack vector in virtualized deployments and aligns Exadata's on-premises security posture with cloud-native security standards. It complements existing features like Trusted Partitions for Oracle Linux Virtualization.

High Availability and Network Resilience

Improved RoCE Network Resilience: ExaPortMon

Every Exadata database and storage server connects to the internal network via dual 100 GbE RoCE ports for an aggregate of 200 Gbps. If a RoCE leaf switch port becomes stalled — appearing online but unable to pass traffic — it can cause cluster instability without triggering a clean failure.

ExaPortMon (introduced in Exadata System Software 24ai) solves this. It continuously monitors both RoCE ports on every server. When it detects a stalled port, it automatically migrates the IP address to the healthy port, keeping network traffic flowing and preventing outages. When the stalled port recovers, ExaPortMon automatically returns the IP address to its original port. No manual intervention required.

Enhanced RoCE Network Security: Exadata Secure RDMA Fabric Isolation

Exadata Secure RDMA Fabric Isolation (Secure Fabric) provides strict network isolation between VM clusters sharing the same physical Exadata infrastructure. It prevents database servers in one VM cluster from communicating with those in another over the RoCE fabric, eliminating lateral movement risk in consolidated and multi-tenant deployments.

Starting with Exadata System Software 25.1, Secure Fabric is automatically selected by default for all new on-premises deployments with X8M and newer hardware — bringing on-premises deployments into alignment with cloud deployments, which have always used Secure Fabric.

Monitoring and Management

AWR & SQL Monitor Enhancements

Oracle Automatic Workload Repository (AWR) on Exadata is enhanced with Exadata-specific storage server metrics alongside standard Oracle wait event data. AWR now collects and reports on XRMEM, Flash Cache, and HDD device performance, enabling DBAs to correlate database wait events with storage-tier behavior in a single report.

SQL Monitor is similarly enhanced, providing end-to-end visibility into query execution that includes storage offload statistics, Smart Scan I/O savings, and flash cache hit rates — all tied to the specific SQL statement being analyzed.

JSON API for Management Server

Exadata's Management Server (MS) now exposes a JSON REST API, enabling programmatic access to Exadata management and monitoring functions. This is a significant modernization of Exadata's management interface, making it easier to integrate Exadata health metrics, alerts, and configuration into modern observability stacks (Grafana, custom dashboards, CI/CD pipelines) without relying solely on traditional CLI tools like cellcli or Enterprise Manager.

Security Enhancements

SNMP v3 Security

Exadata System Software 24.1 introduced mandatory SNMP security improvements across all storage servers and database servers. The key changes:

SNMP v3 is now the recommended and encouraged standard, supporting SHA-256, SHA-384, and SHA-512 authentication protocols for strong authentication and encryption.
All SNMP subscriber definitions now require the connection type to be explicitly specified — administrators can no longer leave it ambiguous.
SNMP v1 remains available but triggers an explicit warning discouraging its use.
Default community strings like public and private are actively discouraged by the system, prompting administrators to set strong, unique values.

This tightens Exadata's management plane security, closing a common vulnerability in enterprise infrastructure where SNMP v1 with default community strings is still widely used.

Why This All Matters: The Convergence Thesis

The strategic bet Oracle is making with Exadata AI Storage is one of convergence over fragmentation. The enterprise AI market has seen an explosion of purpose-built vector databases (Pinecone, Weaviate, Qdrant, Milvus, Chroma), and many organizations are building RAG pipelines that shuffle data between separate systems: a relational database for operational data, a vector database for embeddings, an object store for documents.

Exadata offers a fundamentally different architecture: bring the AI to the data, not the data to the AI. With Oracle AI Database 23ai (now succeeded by Oracle AI Database 26ai as the long-term support release), all of this runs in a single converged engine — relational queries, vector similarity search, JSON document queries, graph traversals, and full-text search — executed as optimized SQL on Exadata hardware. Advanced AI features including AI Vector Search are included at no additional charge.

And with Exadata Exascale reducing the entry cost for Exadata Database Service by up to 95% and enabling organizations to start with as little as 300 GB of storage, the platform is no longer exclusively for Fortune 500 database estates. It is increasingly accessible to organizations of any size that need to build AI applications on enterprise-grade, governed, transactionally consistent data.

Summary Table

Category	Key Feature	Benefit
AI Workloads	AI Smart Scan + Adaptive Top-K	Up to 30x faster vector search; 4.7x less data to DB servers
Memory	XRMEM (DDR5 + RDMA)	14µs read latency; 500 GB/s scan throughput
Caching	Auto KEEP Load, Write Back, Columnar Cache	Zero cold-start for critical objects; analytics at memory speed
Observability	ecstat + CellSQLStat	Real-time per-cell Smart Scan and cache monitoring

Security	Secure Fabric default on-prem	Automatic lateral-movement isolation for VM clusters
Network HA	ExaPortMon	Auto-failover between RoCE ports; no manual intervention
Security	SNMP v3 enforcement	SHA-512 auth; eliminates default community string risk
Management	JSON API for Management Server	Programmatic integration with modern observability stacks

Exadata AI Storage represents Oracle's clearest articulation yet of its "converged data" strategy: a single platform that handles OLTP, analytics, and AI workloads without requiring organizations to build and manage a fragmented ecosystem of specialized tools. With Exadata System Software 25ai, the X11M generation, and the Exascale architecture now generally available across OCI, multicloud (AWS, Azure, Google Cloud), and on-premises, there has never been a better time to evaluate what Exadata can do for your AI application stack.

Billing and Licensing in Exadata Database Service

Tue, 26 Aug 2025 14:09:57 +0000

Oracle Exadata Database Service offers flexible billing and licensing models designed to meet diverse organizational needs. Understanding these options is crucial for optimizing costs while ensuring compliance and performance for your database workloads.

Cost-Effective Software Licensing Models

Oracle provides two primary licensing approaches for Exadata Database Service, each tailored to different organizational scenarios and usage patterns.

License Included Pricing

A license-included consumption model includes Oracle Database Enterprise Edition plus all advanced database options and management packs. This model is ideal for:

Organizations with new workloads requiring immediate database capabilities
Dynamic utilization patterns where database usage varies significantly
Simplified procurement without complex license management
Rapid deployment scenarios where time-to-market is critical

Key benefits of License Included pricing:

All-inclusive pricing with no separate license costs
Access to all Oracle Database features including Advanced Security, Partitioning, and Management Packs
Simplified billing with single line-item charges
No license compliance concerns as everything is handled by Oracle

Bring Your Own License (BYOL)

Oracle BYOL is short for "Bring your own license". It allows you to bring your own license to any public cloud platform. This model offers significant cost advantages for qualifying organizations.

BYOL is ideal for:

Organizations migrating existing workloads with consistent usage patterns
Enterprises with existing Oracle license investments
Predictable workloads where usage patterns are well-established
Cost optimization scenarios where license portability provides savings

Cost Comparison: In Autonomous Database scenarios, Oracle notes that BYOL can lower the database compute costs by around 76%. Similarly, on Exadata Cloud@Customer, the Oracle Database software portion costs about $0.336 per CPU hour with License Included vs $0.0807 with BYOL.

Elastic OCPU Scaling and Pay-As-You-Use

One of the most compelling aspects of Exadata Database Service is its elastic OCPU scaling model where you pay for what you use. This approach offers several advantages:

1. Create Custom Software Image (Grid Infrastructure Image)

The first step involves creating a custom software image that includes:

Oracle Grid Infrastructure components
Specific patches and updates required for your environment
Custom configurations and settings
Security hardening parameters

This image serves as the foundation for all database deployments and ensures consistency across your infrastructure.

2. Create Database Home

After establishing the software image, you create a database home which:

Defines the Oracle Database software installation
Specifies version and patch levels
Establishes the runtime environment for databases
Provides isolation between different database versions

3. Create Database

The database creation process involves:

Defining database parameters and configuration
Setting up storage allocation and management
Configuring memory and compute resources
Establishing backup and recovery settings

4. Create and Manage Pluggable Database (PDB)

Pluggable Database (PDB) management includes:

Creating multiple PDBs within a single container database
Resource allocation and isolation between PDBs
Independent backup and recovery for each PDB
Simplified database consolidation and management

5. Enable Data Guard Association / Active Data Replication

For high availability and disaster recovery, you can enable Data Guard association which provides:

Real-time data replication to standby databases
Automatic failover capabilities
Zero data loss protection (with synchronous replication)
Active Data Guard for read-only workload offloading

Oracle Data Guard Configuration

Oracle Database supports two role transition operations: switchover and failover.

Switchover

Planned role transition between primary and standby databases
Zero data loss during the transition
Reversible operation that can be switched back
Used for maintenance windows or load balancing

Failover

Unplanned role transition due to primary database failure
Automatic activation of standby database
Minimal downtime for critical applications
Ensures business continuity during disasters

Data Guard Requirements

Both the DB systems must be in the same compartment and must meet specific configuration requirements:

Infrastructure Requirements

Both DB systems must be in the same compartment
Both Exadata Cloud Service instances must use the same VCN for single-region deployments
The DB systems must be the same shape type
Network connectivity between primary and standby systems

Database Requirements

The database versions and editions must be identical
Each database must have a unique name to avoid conflicts
Compatible character sets and database parameters
Sufficient storage capacity on both systems

Additional Considerations

By Default Exadata comes with Extreme Performance, so you can configure Active Data Guard
Proper network bandwidth for data replication
Security configurations must be consistent
Backup strategies should be coordinated

Best Practices for Cost Management

License Optimization

Assess existing licenses before choosing between License Included and BYOL
Consider usage patterns when selecting licensing models
Monitor actual consumption to optimize OCPU allocation
Plan for growth to avoid licensing constraints

Resource Management

Implement automated scaling to match demand patterns
Use PDB consolidation to maximize resource utilization
Monitor performance metrics to right-size deployments
Schedule non-critical workloads during off-peak hours

Conclusion

Exadata Database Service's flexible billing and licensing models provide organizations with options to optimize both costs and performance. Whether you choose License Included for simplicity or BYOL for cost savings, the elastic scaling capabilities ensure you only pay for what you use while maintaining enterprise-grade performance and security.

The comprehensive lifecycle management capabilities, combined with robust Data Guard integration, make Exadata Database Service an ideal platform for mission-critical database workloads requiring high availability, security, and cost optimization.
