Reading the release notes is always a good idea – but boring. But I perked up today when I was perusing the latest release notes for 2.2(5) for an upcoming implementation. Here are a few items I think are mentionable. Note that all these features were released in 2.2(4).
Clearly I didn’t deploy any UCS’s around the time that 2.2(4) was released because I totally missed this feature. In the distant IT past (pre 2.1 days), both the Infrastructure and Server firmware had to be at the same level to stay in support. Then came 2.1 which introduced backward compatibility with older Server firmware. Now you’re not necessarily forced to upgrade your blade firmware at the same time as your Infrastructure firmware. Nice. Now with 2.2(4) and Server Packs, blade firmware is backward compatible with Infrastructure firmware. Even better. Of course, this comes with caveats. That being that this feature starts at 2.2(4). So at this point, only 2.2(4) and 2.2(5) support such a configuration. But this is cool. Below is the latest mixed firmware version table from the release notes.
