This blog discusses the Oracle Exadata Smart Flash Cache feature and its architecture, including the write-back flash cache feature.
In an Oracle Real Application Clusters (RAC) environment, all the instances or servers communicate with each other using high-speed interconnects on the private network. If the instance members in a RAC fail to ping or to connect to one other via this private interconnect, all the servers that are physically up and running (and the database instances on those servers) might end up in a condition known as split-brain.
The traditional supply-chain management processes with on-site IT applications are rapidly moving to the modern supply-chain cloud infrastructure. This blog covers the characteristics and benefits of the modern supply chain management in detail.
As part of the Google I/O keynote yesterday, several new features for Google Compute Engine were announced. First, GCE is now available to everyone in a preview and available for signups. They also announced Cloud Datastore, a NoSQL database solution and several other features.
Google Compute Engine looks great, but it's the same old thing from a cloud standpoint. AWS and GCE are both single-vendor, lock-in prone providers. You can't run GCE in your own datacenter. You can't customize and install GCE on both a $200 One-laptop-per-child notebook and a $4,000 MacBook Pro. These platforms are not open.
This year at SXSW, I spoke on why open matters. I used examples to explain how open can triumph over closed like the open Internet and AOL, or Linux vs. Windows. One of my favorite examples is the Betamax.

Rackspace and AppFog are throwing a Happy Hour on Thursday, February 7 at AppsWorld in San Francisco, and we’re asking developers to create an app that helps us choose the beers that will be served at the party. You could win an iPad! All you need to do is RSVP to the party, register for the contest, and then create an app (deployed on AppFog and Rackspace) that allows people to vote for which beers will be served at the happy hour.
That’s right, your votes determine which beers we drink! We’ve selected six beers for the contest: Widmer Hefeweizen, Sierra Nevada Pale Ale, Stella Artois, Lagunitas IPA, Newcastle Brown Ale, and Guinness Stout.
We've moved! The Rackspace DevOps Blog is now hosted on Rackspace Cloud Files (powered by OpenStack Swift) using Octopress. This blog was hosted on WordPress, using a mix of various Rackspace Open Cloud products:
- Cloud Load Balancers
- Cloud Servers
- Cloud Databases
Wayne and I loved this setup and were pleased with performance and security. WordPress on this infrastructure was secure for our purposes (it's a simple blog, not hosting medical data or taking credit cards) so we were happy. So why move?
