Installation of new blade in VIPRION/vCMP System

Let's say I have a VIPRION chassis running vCMP with 2 blades installed. The vCMP guests on this host are set to "Use all slots."   As I understand it, if I install a new blade into the chassis, ...

I plan on having the switch interfaces configured and ready to be plugged in. They just won't be plugged in IMMEDIATELY as the blade is inserted.. perhaps 30-60seconds later. I just want to make sure there the blade won't try to start processing traffic before I can get the interfaces cabled.

 

@Josh - thanks for the detailed response! Ours are cabled directly to Nexus 7k's. I typically have 4x10GB for each blade (2x10 for the internal side, 2x10 for the external). Each blade also has a switchport on the "sync" or "ha" VLAN that is used for sync and network failover traffic. I don't typically interconnect individual blades together.

 

Thanks,

 

Josh

Yes, we do use VPC. So, if we are talking about a single blade: 1.1 -> internal-trunk -> NEXUS-7K-01 -> VPC 100 / 1.2 -> internal-trunk -> NEXUS-7K-02 -> VPC 100 / 1.3 -> external-trunk -> NEXUS-7K-01 -> VPC 200 / 1.4 -> external-trunk -> NEXUS-7K-02 -> VPC 200 / 1.8 -> ha-trunk -> private/non-routed VLAN I didn't know blades could connect to other blades through the chassis. I thought every blade had to be cabled individually. I will continue to do it this way anyways, as it provides higher throughput and more redundancy, I suppose. Um, yeah! I have also noticed that when I remove a blade with no active guests, I get traffic interruption. (sorry, this forum is mangling my line breaks)
