Cisco UCS B-Series Review
Replacing Fabric interconnects and IOMs can be done while the system is up and serving production data. However, I'd like to see an integrated management interface for all NetApp Flexpod products.
The features of Cisco UCS that are of the most value to me is the ability to build Service Profiles for servers based on your needs. You can add HBAs and NICs to servers as needed, and you can remove them just as easily.
Also, with UCS, updating firmware and drivers has been simplified and can be done throughout the system simply by associating new firmware policies to the hardware. You can also run different versions of firmware as needed to support legacy applications.
Improvements to My Organization:
UCS has made it possible to replace and upgrade servers quickly and easily while keeping things up and running for the enterprise.
Replacing the Fabric interconnects and IOMs can be done while the system is up and serving production data. You can almost effectively negate downtime from your organization as a result.
Room for Improvement:
I would really like to see an integrated management interface for all the products for FlexPod, as well as a verification tool like Immersive that can give you feedback about your compatibility with FlexPod guidelines.
Get a qualified vendor to help you go through the process, and take some training to get familiar with how things work together.
