NimbostratusInstallation 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, ...

NimbostratusI 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

NimbostratusYes, 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.
