ODA X6 2S 2M 2L HA: Small Medium Large and High Availability

There are 4 models of Oracle Database Appliance with the new ODA X6 which is for the moment the latest ODA hardware version. One is similar to the previous X5-2 one, and 3 smaller ones known as ODA Lite. They are 1 year old already, here is a small recap of the differences and links to more detail.

The ODA X6 are composed with Oracle Server X6-2:

ODA X6 installation: re-image

The Oracle Database Appliance is shipped with a bare-metal installation which may not be the latest version. You may want to have it virtualized, or get the latest version to avoid further upgrade, or install an earlier version to be in the same configuration as another ODA already in production. The easiest for all cases is to start with a re-image as soon as the ODA is plugged. This post is not a documentation, just a quick cheat sheet.

I don’t want to spend hours in the data center, so the first step, once the ODA is racked, cabled and plugged, is to get it accessible from the management network. Then all tasks can be done from a laptop, accessing the ILOM interface through a browser (Java required, and preferably 32-bits) before the public network is setup.

I recently had a question from a customer about the usefulness of the solution and what it brings to the HA table. Well here you go.

Oracle Database Appliance: Storage Performance — Part 1

Today I want to show what kind of IO performance we can get from Oracle Database Appliance (ODA). In this part, I will focus on hard disks. That’s right — those good old brown spinning disks. I often use Oracle ORION tool to stress-test an IO subsystem and find it’s limits. It’s a very simple [...]
