We have a newly deployed UCS domain, and we have added it to Solarwinds Orion to keep an eye on bandwidth usage. I'm finding that the portchannels and ethernet connections between the blade servers and the IO Modules is quite high with a lot of spiking. Most of the time some of the PCs/ ethernet connections are showing almost total saturation of their 10 Gbps connections. What is strange is that there is then very little traffic being reported out of the virtual ethernet and HBA connections for the blades, and coming out of the IO modules to the FIs. The blade servers seem to be operating normally, but I'm unclear on whether this is causing a performance issue. Here's the equipment involved: 6332-16UP FIs 1 40-Gbps uplink from each IOM to the FI 2304 IO Modules B200M5 blades with VIC 1340 adapters 4.0.4b firmware RHEL 7.6 with two vNICs and fabric failover enabled. Has anyone seen this before, and have any clue what is going on here? ... View more

Here I am with another UCS Central question... is it a problem to have two domains in the same domain group, if they have different hardware?  I know that Central now uses maintenance tags for infrastructure firmware upgrades, which I use.  I prefer to use Central for managing firmware, but would like to have consistent settings and pools between a 6248 domain and a 6332 domain.  Thoughts? ...

Hi, I am just wondering what the effects are of UCS Central license expiration.  If a trial expires, does the UCS domains and service profiles become unusable (causing an outage), or do the profiles and configurations stay, but changes are not allowed?  Thanks! ... View more

I'm reviewing the tools we use to manage UCS, as I am configuring another domain (our fourth).  Right now we have one UCS Central appliance, and have been running it for something like five or six years (it's been updated to 2.01i).  Is there any benefit to having a second UCS Central appliance for nonprod environments, and keeping the existing for prod?  I like the idea of having a separate instance for nonprod in some ways, but don't like the idea of re-defining VLANs, etc., and wonder if that defeats the purpose of this appliance.  Is it possible to move a UCS domain to a new Central server, if I just wanted to build a new one?  Unfortunately, it looks like the current domains were added via IP address.  Or should I just keep the appliance and look toward when Intersight is ready for prime time?  I just thought it wouldn't hurt to see what others thought as I continue to research.  Thanks! ...

We just replaced our first Fabric Interconnects with new ones, and need to get rid of our old FIs.  I know that all the service profile, configuration, etc. is stored on local hard disks on the FIs.  I plan on plugging them in one last time for an "erase configuration" command to delete the config.  Is there anything else people usually do to decom FIs?  If they were servers, we would degaus the hard disks.  Does anyone do anything that extreme?  Thanks! ...
