DATA – The world’s most valuable resource like Water
DATA
Unique
Data cannot be substituted by other
data, because each carries different
information.
[Less Transformation is Better]
Always There
Data can be consumed over and over
again by different parties.
[Easy and Repeatable Access is a Must]
Experience
Data can be accurately evaluated only
after data have been experienced.
[Time to Experience is Important]

Single purpose databases are advocated by cloud vendors and startups
Combining “best-of-breed” drives “worst-of-weaknesses”
• Use of single-purpose databases has been the source
of a large increase in data management complexity
• Require apps to use separate proprietary APIs for each
database
• Separately implement security policies for every
database technology
• Unique high availability and scalability tools for each
database type
• Complex management and integration
• End-to-End security, availability, scalability,
consistency, etc. means weakest of the databases that
are used
AWS and other vendors want customers to run multiple
Single-Purpose databases because it drives up
subscriptions & services (= More Revenue $$$$)

Transactions And other single
purpose databases!

• Modern applications require many different:
– Data types - Relational, Document, Spatial, Graph, etc.
– Workloads - Transactions, analytics, ML, IoT, etc.
• Each data type and workload requires different database algorithms
• Two possible data strategies:
– Use single-purpose “best-of-breed” database for each data type and
workload
– Use a converged database for all data types and workloads
Oracle’s Strategy:
– Run Converged, Open, Oracle Database for multiple data types
and workloads
To become data-driven customers need a modern data strategy
Many specialized databases vs one converged database

• Exadata uses frequent heartbeat messages
between nodes to detect possible server failure
• Server failure detection normally requires long
timeout to avoid false server evictions from
cluster
• Hard to quickly distinguish between slow response to
heartbeat due to very high CPU load, and server failure
• Exadata uses RDMA to quickly confirm server
failure
• RDMA uses hardware - remote ports reply even if
software is slow
• 4 RDMA Reads are sent to suspect server, across
all combinations of source and target ports
• If all 4 RDMAs fail, server is evicted from cluster

Kernel-based Virtual Machine (KVM): virtualization module in the Linux kernel, allowing the
kernel to function as a hypervisor
• KVM has become the industry standard for Cloud and on-premises deployments
Effective isolation of CPU, memory, OS, and sysadmin for consolidated workloads
• Cross department consolidation, test/dev, non-database applications, deployment in
cloud / hosted environments
Exadata VMs deliver near raw hardware performance
• I/Os go directly to high-speed network bypassing hypervisor
• Combine with unique Exadata network and I/O prioritization to achieve unique full stack
isolation
Trusted Partitions allow licensing by virtual machine
KVM in X9M provides better virtualization metrics compared to OVM (in X8 and earlier)
• Higher VM Memory: up to 2 TB RAM per DB server (max guest VM memory: 1870GB)
• 50% more guest VMs per DB server (12 vs 8) compared to X8
