Making drawings with Oracle hardware components [31010]
Oracle-Servers.zip
Kemer Thompson writes, "For those of you who like to (or need to) create architectural drawings with reasonable renditions of components and all the requisite connections, you are probably already aware of Microsoft Visio, or for those of you who prefer Macs (such as myself), Omnigraffle Pro. Did you know that we have an open repository with a growing selection of components on VisioCafe? We just updated this Tuesday night, adding stencils of Oracles new SPARC T5 and SPARC M5 servers. You will find them in the zip bundle Oracle-Servers.
We have also added Visio templates for Oracle's Exadata Database Machines. In case you didnt know the difference between stencils and templates, templates provide a more powerful (and efficient) representation that allows you to reorganize the racks to match your actual configuration..."

Evaluating and Comparing Oracle Database Appliance Performance [29779]
White Paper Reports Performance on OLTP- and DSS-type Workloads
"Evaluating and Comparing Oracle Database Appliance Performance," an Oracle white paper, documents the performance testing on OLTP- and DSS-like workloads executing of Oracle Database Appliance. During the performance testing Oracle Database Appliance demonstrated scalable performance for both workloads. Using all 24 cores, Oracle Database Appliance supported 10,000 concurrent Swingbench users and more than 9800 Swingbench transactions per second while maintaining an average response time of less than 30ms. With the DSS type workload, Oracle Database Appliance easily supported a sustained IO throughput of more than 2400 MB/Second. Some configuration adjustments and tuning were needed to obtain maximum performance from the Oracle Database Appliance.

Big Data Appliance X3-2 Updates [29776]
Review of Changes in Hardware and Software
The release of Big Data Appliance X3-2 includes improvements in both the hardware and in the software, reports Jean-Pierre Dijcks. The new 2 x 8-core count CPU (as compared to the earlier 2 x 6-core CPU) results in more parallel compute power while saving some 30% in energy and heat. Changes in the software include CDH 4.1.2 and the default set up of highly available name nodes for Hadoop, the Oracle Enterprise Manager management of the BDA, the uptake of the Oracle R Distribution and the updates to Oracle NoSQL Database, as well as numerous bug fixes.

Oracle Announces 400GB Flash Accelerator F40 PCIe Card Support [29381]
Accelerates Storage Intensive Applications on Sun Server X3-2L System
Oracle has announced the Flash Accelerator F40 PCIe card support for Sun Server X3-2L Systems. The F40, which is ideal for running Oracle databases with Smart Flash Cache feature available in Oracle 11gR2 and above, has been designed as a high-performance 400GB (Gigabyte) PCIe Flash Card able to accelerate storage intensive applications with random I/O workloads and improve server efficiency by reducing storage latency and increasing I/O throughput.

Collaboration: An Unexpected Advantage of Engineered Systems [28584]
Team Approach, Involving Users, Results in Quicker Fixes
There are unexpected benefits, collaborative in nature, in the use of engineered systems, contends User 12244672, citing two examples of such advantages. These involve solving a node eviction issue running Oracle Database 11g R2 with Solaris 11 SRU 12 under extreme load on the ExaLego test system. The fix went into all Solaris releases just 10 days from initial discovery. In the second example a customer experienced sporadic performance degradation, and a number of contributing factors were discovered, including tunable parameters. A collaborative investigation identified the root cause to be a CPU bound networking thread being starved of CPU cycles under extreme load.

Which IO Option for Which Server? [25151]
Cross Platform IO Support
If you need to know which IO option cards are available for which server, there is now a new portal on wikis.oracle.com.
This wiki contains a full list of IO options, ordered by server, and maintained for all current systems. Also included is the number of cards supported on each system.
The same information, for all current as well as for all older models, is available in the "Systems Handbook", the ultimate answerbook for all hardware questions.
