Cisco UCS FlexFlash Configuration of Secure Digital (SD) Card
So, for the newbee to Cisco UCS, its confusing about the firmware. In this post I am trying to clarify few aspects of this, feel free to post comment below if you have any questions and I will get back to you.
The CISCO UCS firmware is bundled into two packages as given below:
1. Infrastructure Firmware
In Infrastructure Software firmware we update the firmware of the following
- Cisco UCS Manager software
- Kernel and system firmware for the fabric interconnects
- I/O module firmware
2. Server Firmware
Cisco UCS
B-Series Blade Server Software Bundle
- CIMC firmware
- BIOS firmware
- Adapter firmware
- Board controller firmware
- Third-party firmware images required by the new server
This also includes the firmware of Adapter, BIOS, FC Adapters, HBA Option ROM, Storage, Controller, Local Disk
Cisco UCS
C-Series Rack-Mount UCS-Managed Server Software
- CIMC firmware
- BIOS firmware
- Adapter firmware
- Board controller firmware
- Third-party firmware images required by the new server
As most of you might be aware the UCS manager is the GUI Java based which allows you to fully manage the CISCO Unified Computing System.
Note I have noticed that the Java version 7 update 40 is only compatible with the UCS Manager.
So, where does the UCS Manager run ?
This was one of my first questions, Well the Software of the UCS Manager runs on the FI ( Fabric Interconnect 62xx) as we have a pair of Fabric Interconnect it has got resilience.
The UCS System is designed to be highly scalable and available, so upgrading the firmware should not bring any outage to the environment. However Cisco still suggests to arrange a Change windows and get this done out of hours or the quite period of your business.
This UCS Manager is bundled in the Infrastructure Firmware Software along with the Kernal update of the FI which is the NXOS, Finally we have the I/O Module firmware which is a part of the Infrastructure firmware software too.
The Other Bundle is the Server Firmware which has the firmware for BIOS, the Blades, Adapter, Board controller etc.
