Cisco UCS Firmware 2.1(1b) released

New Cisco UCS firmware has now released! Their long anticipated first patch release of the 2.1 firmware, 2.1(1b) is out and you can download it today. Version 2.1, released in November of 2012, adds a number of great new features including the ability to rename service profiles. Since 2.1 added so many new features, there are bound to be some bugs/issues. So after several months of 2.1 in the field, you may now want to strongly consider jumping on 2.1(1b).

2.1(1b) adds a few new features, most notable in my book as the ability to run memory at 1333MHz vice 1066MHz in the B200 M3/C240M3 servers when all three DIMM slots are populated with memory. That’s great for a VDI blade, where you may fully populate it with 384GB using 16GB DIMMs.

Release 2.1(1b) adds support for the following:
•Cisco UCS B200 M3 blade server configurations with a single CPU
This patch release provides support for UCS B200 M3 blade server configurations with a single CPU, in addition to the previously supported dual CPU configurations.

New Software Features in Release 2.1(1b) adds support for the following:
•BIOS Policy Settings—Provides the ability to select refresh interval rate for internal memory.
•Memory Speed—Enables 1333 MHz memory speed for 8GB/16GB 1600-MHz RDIMMs populated with 3 DIMMs Per Channel/1.5v on the Cisco UCS B200 M3 blade server and Cisco UCS C240 M3 rack server.
•Call Home—Enables you to configure call home for CMOS battery voltage low alert.

There’s also a nice, relatively short, list of resolved caveats. I won’t post all of those, but you can check out the full release notes here.

On March 6, 2013 Cisco also released v2.1.1d of the UCS drivers ISO.
