Oracle releases Exadata X4 with optimizations for data warehousing

”Oracle Exadata Database Machine is the best platform on which to run the Oracle Database and the X4 release extends that value proposition,” said Oracle President Mark Hurd. “As private database clouds grow in popularity, the strengths of Oracle Exadata around performance, availability and quality of service set it apart from all alternatives.”

We have just announced the release of the fifth-generation of our flagship database machine: Oracle Exadata Database Machine X4. This latest release introduces new hardware and software to accelerate performance, increase capacity, and improve efficiency and quality-of-service for enterprise data warehouse deployments.

Performance of all data warehousing workloads is accelerated by new flash caching algorithms that focus on table and partition scan workloads that are common in Data Warehouses. Tables that are larger than flash are now automatically partially cached in flash and read concurrently from both flash and disk to speed throughput.

Other key highlights are:

1) Improved workload management
Exadata X4-2 includes new workload management features that will improve the management of data warehouse workloads. Exadata now has the unique ability to transparently prioritize requests as they flow from database servers, through network adapters and network switches, to storage, and back.

We are using a new generation of InfiniBand network protocols to ensure that network-intensive workloads such as reporting, batch and backups do not delay response-time sensitive interactive workloads. Which is great news for IT teams that have to define and manage service level agreements.

2) Bigger flash cache for even faster performance
We have increased the amount of physical flash within a full rack to 44 TB per full rack. However, the capacity of the logical flash cache has increased by 100% to 88 TB per full rack.

3) Hardware driven compression/decompression

A feature that is unique to Exadata is the Flash Cache Compression. This transparently compresses database data into flash using hardware acceleration to compress and decompress data with zero performance overhead.

4) In-memory processing
For in-memory workloads we increased maximum memory capacity by 100% to 4TB in full rack (using memory expansion kits) which means more workloads will be able to run in-memory with extremely fast response times.

5) Increased support for big data
To support big data projects we increased the capacity of the high performance disks to over 200 TB per full rack and for high capacity disks the storage capacity is now 672 TB per full rack. Once you factor in Oracle Exadata's compression technologies then a full rack is capable of storing petabytes of user data.

Swiss Re increases data warehouse performance and deploys in record time

Great information on yet another data warehouse deployment on Exadata.

A little background on Swiss Re:

In 2002, Swiss Re established a data warehouse for its client markets and products to gather reinsurance information across all organizational units into an integrated structure. The data warehouse provided the basis for reporting at the group level with drill-down capability to individual contracts, while facilitating application integration and data exchange by using common data standards. Initially focusing on property and casualty reinsurance information only, it now includes life and health reinsurance, insurance, and nonlife insurance information.

Key highlights of the benefits that Swiss Re achieved by using Exadata:

  • Reduced the time to feed the data warehouse and generate data marts by 58%
  • Reduced average runtime by 24% for standard reports
  • comfortably loading two data warehouse refreshes per day with incremental feeds
  • Freed up technical experts by significantly minimizing time spent on tuning activities

Most importantly this was one of the fastest project deployments in Swiss Re's history. They went from installation to production in just four months! What is truly surprising is the that it only took two weeks between power-on to testing the machine with full data volumes! Business teams at Swiss Re are now able to fully exploit up-to-date analytics across property, casualty, life, health insurance, and reinsurance lines to identify successful products.

These points are highlighted in the following quotes from Dr. Stephan Gutzwiller, Head of Data Warehouse Services at Swiss Re: 

"We were operating a complete Oracle stack, including servers, storage area network, operating systems, and databases that was well optimized and delivered very good performance over an extended period of time. When a hardware replacement was scheduled for 2012, Oracle Exadata was a natural choice—and the performance increase was impressive. It enabled us to deliver analytics to our internal customers faster, without hiring more IT staff"

“The high quality data that is readily available with Oracle Exadata gives us the insight and agility we need to cater to client needs. We also can continue re-engineering to keep up with the increasing demand without having to grow the organization. This combination creates excellent business value.”
