[cisco-voip] BE7K or not?

Thu Dec 3 15:45:07 EST 2015

Thanks for everyone's responses. I read on one of the pages that BE7K comes pre-loaded with UCCx 4 vCPU OVA, but I'm guessing that I can run whatever OVA I want as long as it fits? 

We were told that the BE7K is not customizable, even after ordering, so adding memory or anything like that is not permitted. This sort of makes me cringe. I like having the opportunity to add memory and/or additional NICs as with the other TRCs. Can't really justify it now, but as future versions come up, I'd like to have the ability to add more memory if the CUCM v11 or v12 version requires it. 

It's really only memory and NIC throughput that I can see having to increase and only as the apps demand more with each version.

The newest BE7ks are built on C240 M4 hardware. The BE7H-M4-K9 is 20 cores, 128 GB RAM, 4+ TB of available disk space, the BE7M-M4-K9 is 12 cores, 64 GB RAM, and around 2.6 TB available disk. 

Cisco states on the data sheet that BE7k is “optimized for enterprise-scale organizations with 1000 to 5000 users and 3000 to 15,000 devices” but they also note “For more capacity to support larger sized deployments, simply stack additional servers. And in smaller sized deployments with less than 1000 users, typically more applications can be supported per server.” 

I haven’t seen any practical limitations, and as pointed out by someone else you can use the VM Placement Tool to see what OVAs fit, and scale to size.

Sorry for the confusion... We had originally planned to install C240 M3s but swapped them out for the C240 M4s instead.

Or by "new" do you mean something else other than the 240M4s?

We're in the process of converting to Cisco UC and recently during our design phase swapped out the BE7Ks in favor of the new UCS C series severs. C240 M4s are used for the majority of our cluster.

is your friend, pick your server model and the ovas you will use. 

In general though BE7K should be fine. No limitations besides overall resources. Just gotta figure out how many you need or want

We're spec'ing out some new UCS servers for our next upgrades. 

Still trying to figure out what, if any, limitations going with a BE7K might have. Does anyone care to share a reason why we shouldn't go with BE7K, or why we shouldn't go with a la cart using the BOM? 

There was once an issue with a limitation of users/devices, but I think that's gone now. My biggest concern is trying to do something on the BE7K and finding out only after that it's not allowed or supported. 

Any ideas would be great.
