"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."
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 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.
