Friday Spotlight: Oracle Linux and Database Smart Flash Cache

Happy Friday!

One of the coolest, yet perhaps not best known, features of running Oracle Database and Oracle Linux together is Database Smart Flash Cache. Wim Coekaerts put it this way on his blog earlier this week:

"Basically, if you have flash devices attached to your server, you can use this flash memory to increase the size of the buffer cache. So instead of aging blocks out of the buffer cache and having to go back to reading them from disk, they move to the much, much faster flash storage as a secondary fast buffer cache (for reads, not writes)."

So, this gives you a way to significantly increase performance on your systems running the Oracle Database and Oracle Linux. How cool is that? Wim then goes on to describe the few easy steps it takes to get it up and running.

I highly recommend checking out Wim's blog entry on this fantastic feature, and there is also an in-depth white paper you can have a read through for even more info.

Have a great week!

PARTNER News: Tips and Guidelines from Avago (formerly LSI)

In this blog write-up we would like to focus our attention to one of our IHV partners, Avago (formerly LSI) . Avago and Oracle have been collaborating at many levels for many years.  At the lowest level, Avago and Oracle engineer solutions to inbox advanced features in our I/O device drivers.  We collaborate to test, verify and optimize these drivers in Oracle Linux with Unbreakable Enterprise Kernel. Both LSI Nytro and Sun F-Series PCIe flash devices are supported inbox in Oracle Linux with Unbreakable Enterprise Kernel. By collaborating early in the engineering design cycle we can find and resolve issues sooner and deliver to the end-customer a fully optimized platform for I/O efficiency and data protection. 

Hear more about the partnership and benefits in this podcast  LSI and Oracle Partnership.

Avago had also been working on technical whitepaper and video whiteboard to explain some of the optimizations you can achieve by using smart flash cache with Oracle Linux.

Friday Spotlight: Improve Database Performance Using Database Smart Flash Cache

Happy Friday!

Our spotlight this week is on a new blog and article on Oracle Technology Network about improving database performance using Database Smart Flash Cache. From the introduction to the article:

"This article describes how to obtain performance gains and improve response times by combining Oracle's Sun Flash Accelerator F40 PCIe Card with the Database Smart Flash Cache feature of Oracle Database running on Oracle Linux with the Unbreakable Enterprise Kernel."

Head on over to OTN Garage to read the summary (and see a nice picture from Las Vegas at COLLABORATE14) and follow the links to the article.

See you next week!

Friday Spotlight: Accelerating MySQL on Oracle Linux with Flash

Happy Friday!

Our spotlight this week is on a brand new white paper that can help you get the most out of MySQL running on Oracle Linux, with the help of Oracle's Sun Flash Accelerator F80 PCIe card. To give you an idea of the Oracle Linux part of this, here is an except from the paper's intro:

"Oracle Linux with Unbreakable Enterprise Kernel (UEK) was chosen for this study for several key reasons including its upstream support for the latest hardware relevant to modern data center operations, and SSD support and performance features such as SSD detect. In addition, MySQL database workloads benefit from the platform’s deep integration with the solution stack, optimizations resulting from industry collaborations and enhancements in the UEK.

Read the white paper "Performance Advantages of Running an Oracle MySQL Replicated Database on Oracle Linux with Oracle’s Sun Flash Accelerator F80 PCIe Card"

We'll see you next week!

Fusion-io Showcases Data Integrity with Oracle Linux at Oracle OpenWorld 2013

Fusion-io (NYSE: FIO) today announced ION Data Accelerator demonstrations at Oracle OpenWorld that delivers accelerated performance for Oracle Database environments, as well as enhanced end-to-end data integrity verified by the T10 Protection Information (T10 PI) specification. With Fusion ION Data Accelerator Software and Fusion ioDrive2 server flash memory products supporting the Oracle Linux operating system, Oracle Database, and Emulex LightPulse® Gen 5 Fibre Channel (16Gb Fibre Channel) Host Bus Adapters (HBAs).
Using the T10 PI specification, data corruption is noticed and fixed as it is written to shared storage, helping ensure reliability for enterprise applications.

The T10 PI data integrity demonstration features the Fusion ION Data Accelerator shared storage solution with Oracle Linux and Emulex Gen 5 FC HBAs. The demonstration incorporates Oracle Linux with the Unbreakable Enterprise Kernel, which supports integrity features that leverage the T10 PI specification.

The data integrity testing was conducted by inserting corrupt data into the system and verifying that despite the insertions, data integrity on ION Data Accelerator was not compromised. Using the T10 PI specification, data corruption is noticed and fixed as it is written to shared storage, helping ensure reliability for enterprise applications. The demonstration incorporates Oracle Linux with the Unbreakable Enterprise Kernel, which supports integrity features that leverage the T10 PI specification. Additional technical details about the T10 PI reliability demo are available here

Live demonstration of the Data integrity solution is being featured at Fusion-io booth 1127 during Oracle OpenWorld 2013 in San Francisco from September 22-26. Read the press release.

Oracle Database Smart Flash Cache: Only on Oracle Linux and Oracle Solaris

Oracle Database Smart Flash Cache is a feature that was first introduced with Oracle Database 11g Release 2. Only available on Oracle Linux and Oracle Solaris, this feature increases the size of the database buffer cache without having to add RAM to the system. In effect, it acts as a second level cache on flash memory and will especially benefit read-intensive database applications.

The Oracle Database Smart Flash Cache white paper concludes:

Available at no additional cost, Database Smart Flash Cache on Oracle Solaris and Oracle Linux has the potential to offer considerable benefit to users of Oracle Database 11g Release 2 with disk-bound read-mostly or read-only workloads, through the simple addition of flash storage such as the Sun Storage F5100 Flash Array or the Sun Flash Accelerator F20 PCIe Card.

Read the white paper.
