What is InfiniBand in Exadata?
Infiniband Network of Exadata Infiniband Network is a high-performance, very low-latency network layer that is active-active in all directions at 40 Gb / sec, which enables communication between the Database Server and Storage Server like following picture.
What is the difference between Exadata and Oracle?
Differences: Oracle Database Appliance is not Exadata. Exadata is a pre-configured combination of hardware and software that provides an infrastructure solely for running Oracle Database. Oracle Database Appliance (ODA) is an integrated highly available (HA) database and applications system in a single box.
How many types of networks are there in Exadata?
three networks
Exadata Database Machine requires a minimum of three networks, and there are interfaces available for additional networks. Each network must be on a separate and distinct subnet.
What are the 3 major software components of the Exadata storage server?
I/O Resource Management (IORM) Offloading of Data Search and Retrieval Processing. Offloading of Incremental Backup Processing.
What does an InfiniBand switch do?
NVIDIA Quantum InfiniBand switches provide high-bandwidth performance, low power, and scalability, reducing capital and operating expenses and providing the best return on investment. NVIDIA Quantum switches optimize data center connectivity with advanced routing and congestion avoidance capabilities.
What is Exadata storage server software?
It runs the Exadata Storage Server Software that provides the unique and powerful Exadata technology including Smart Scan, Storage Indexes, Smart Flash Cache, Smart Flash Logging, Flash Cache Compression, IO Resource Manager, Network Resource Management, and Hybrid Columnar Compression.
Why is Exadata so fast?
Exadata has an internal storage network that provides both high bandwidth and low latency. This storage network is currently based on Infiniband, but the specific physical technology used inside of Exadata isn’t nearly as important as what it delivers.
Is Oracle Exadata a data warehouse?
By using the Oracle Exadata Database Machine as your data warehouse platform you have a balanced, high performance hardware configuration.
How Fast Is Exadata?
For this, the world’s fastest OLTP Database machine just got even faster (and not by a little!). Using sophisticated software introduced with Exadata X8M and persistent memory, we saw IOs per second reach 16 million in a single rack. Now, Exadata X9M boasts 27.6 million 8k read IOs per second, a 70% increase!
What is Oracle Exadata server?
Oracle Exadata allows customers to run Oracle Database with the same high performance, scale, and availability wherever needed. Workloads easily move between on-premises data centers, Cloud@Customer deployments, and Oracle Cloud Infrastructure, enabling customers to modernize operations and reduce costs.
What are the benefits of InfiniBand?
Fabric consolidation and low energy usage: InfiniBand can consolidate networking, clustering, and storage data over a single fabric which significantly lowers the overall power, real estate and management overhead required for servers and storage.
What is the difference between InfiniBand and Ethernet?
InfiniBand also has much lower latency than Ethernet and, most importantly, it incorporates processing engines inside the network that accelerate data processing for deep learning and high-performance computing. These are key technology advantages for any compute- and data-intensive application.
What layer is InfiniBand?
InfiniBand architecture offers a significant improvement for the transport layer over other technologies such as Ethernet: all functions are implemented in the hardware.
Infiniband Network is a high-performance, very low-latency network layer that is active-active in all directions at 40 Gb / sec, which enables communication between the Database Server and Storage Server like following picture. Full and half Exadata have one main and two secondary Infiniband Switches.
How to monitor PDU current in Oracle Exadata rack?
The PDU current can be monitored directly or with Oracle Enterprise Manager Grid Control. Configure the threshold settings to monitor the PDUs. The threshold settings depend on the size of Oracle Exadata Rack and type PDU. The configurable threshold values for each metering unit module and phase are Info low, Pre Warning, and Alarm.
What are the Oracle Exadata Database Machine spares?
Oracle Exadata Database Machines include a spares kit. These tables list the components included for each type of Exadata Database Machine model and configuration. In the following tables, for raw capacity, 1 GB = 1 billion bytes. Capacity is calculated using normal space terminology of 1 TB = 1024 * 1024 * 1024 * 1024 bytes.
How do I reclaim disk space from Exadata using InfiniBand network fabric?
On systems with InfiniBand Network Fabric only, run /opt/oracle.SupportTools/reclaimdisks.sh -free -reclaim on each database server before installing any software. The command reclaims disk space reserved for the deployment type not selected, which is not required on RoCE -based Exadata database servers.
