Oracle Exadata is an enterprise database platform that runs Oracle Database workloads of any scale and criticality with high performance, availability, and security. Exadata’s scale-out design employs optimizations that let transaction processing, analytics, machine learning, and mixed workloads run faster. Consolidating diverse Oracle Database workloads on Exadata platforms in enterprise data centers, Oracle Cloud Infrastructure (OCI), and multicloud environments helps organizations increase…

Oracle's Exalogic is a converged infrastructure appliance.
It's hard to compare Oracle Exalogic Engineered Systems with anything else on the market. It's so purpose built for application performance and intended to be used in conjunction with other Oracle Engineered Systems. As I alluded to earlier in this review the cost may not be …
Oracle Exadata is well-suited for environments where massive performance for Oracle databases is required. Storage indexes reduce the unnecessary I/O. Smart Flash Cache accelerates random reads/writes.
Our OLTP application demands very high concurrency. Multi-node Exadata provides high availability and zero downtime during DB patching. It comes with lots of built-in automations, so it reduces many routine tasks for sysadmins, like network, storage, and VM configuration, and it also reduces many Oracle DBA tasks, like Oracle software installation, patching, and upgrades.
Oracle Exalogic in conjunction with an Oracle Exadata based platform is what I would consider the best of breed solution; however the performance may be overkill for what you need. Don't spend the money unless you need the performance, Oracle offers other solutions at a much lower cost. Purchase what you need not what's the shiny new product.
Oracle Database : Deliver industry-leading security, high availability and scalability with Oracle Database, which has been significantly enhanced to take advantage of the Oracle Exadata Storage Servers.
Exadata Smart Scan : Improve query performance by offloading intensive query processing and data mining scoring to scalable intelligent storage servers.
Smart Flash Cache : Transparently cache 'hot' read and write data to fast solid-state storage, improving query response times and throughput. Exadata systems use the latest PCI flash technology rather than flash disks. PCI flash delivers ultra-high performance by placing flash directly on the high speed PCI bus rather than behind slow disk controllers.
Hybrid Columnar Compression : Reduce the size of data warehousing tables by 10x, and archive tables by 50x, to improve performance and lower storage costs for primary, standby, and backup databases. Query high, query low, archive high and archive low.
Infiniband Network : Connect multiple Oracle Exadata Database Machines using the InfiniBand fabric to form a larger single system image configuration. Each InfiniBand link provides 40 Gigabits of bandwidth–many times higher than traditional storage or server networks.
Petabyte Scalability : Easily scale data warehouse to support enterprise data growth.
Private Cloud: in the virtual configuration, you can create several accounts and assign different resources (vCPU, RAM, etc.) to several departments in your organization.
SDP & Infiband: Oracle Exalogic can be connected to Oracle Exadata using Infiniband Fabric, to take advantage of high bandwidth and low latency network to connect Weblogic to Oracle Database.
Standardization: Oracle Weblogic Server running on Oracle Exalogic is the same software running on a normal Linux machine, so you can easily move Java applications without changing it, and immediately benefit from the Exalogic Optimizations.
The process of patching and upgrade of Exadata server components could be improved with a goal to minimize the overall effort, make it fully automated and transparent.
Improved guidelines and possibly more sophisticated tools for sizing of new Exadata servers for migration from old legacy hardware.
Currently, the management of Exalogic is a little arcane. There is a good chance that Oracle can bring flexibility into the control stack because we have seen changes with each version of the software Echo was an improvement and foxtrot even more so. The ability to easily change VM shapes was another welcome change.
Again the fact arises that to build a very high performance machine there will be idiosyncrasies and a certain amount of retraining may be required. I think this is one area where Exalogic lacks not as a product but as a solution is that there isn't as much good knowledge available about it as there is for other engineered systems.
The Exalogic default setup could do with an SSD storage option, currently the onboard comes with a spinning disk.
I am comparing Exadata with the Oracle RAC database experience. In addition to Oracle RAC features, Exadata provides automatic performance optimization through Smart Scan and storage indexes. Deep integration with the Oracle ecosystem and tight coupling with Oracle Enterprise Manager for monitoring and management. Some downsides of Exadata are: a steep learning curve, concepts like cell offloading, IORM, and flash cache behavior aren’t intuitive initially. Operating Exadata requires specialized DBA skills.
It is a very condensed version of what used to be rows of servers. I like that storage, networking and compute nodes fit in one rack. The power and the software are top notch. The only problem is cost. You need to do some serious processing to get the true value out of the Exalogic system.
Oracle Exadata Database Machine had the best performance overall hands down. It clearly beat the competition and we were seeing 1000X improvement on SAP HANA. Oracle Exadata Database Machine beat that without us refactoring our code. To achieve that in HANA, we had to refactor the code somewhat. Now this was for our limited POC of 5 use cases. Given the large number of stored procedures we had in Sybase, we need to capture more production metrics but we are seeing incredible performance.
It's hard to compare Oracle Exalogic Engineered Systems with anything else on the market. It's so purpose built for application performance and intended to be used in conjunction with other Oracle Engineered Systems. As I alluded to earlier in this review the cost may not be worth the investment if the performance isn't needed. Oracle offers other solutions like the Oracle PCA which will meet the need for licensing compliance at a much lower cost of ownership and may fit better into your current infrastructure.
Single support from a single vendor with both machine and database from Oracle, which is costing us less.
With Exadata, we need less technical manpower and less technical support. A business transaction with the integrated and centralized database helps us focus on other business needs.
We don't need to buy additional licenses and Hardware for the next 3 to 5 years.
