Hyper-V 2012 R2 Networking Configuration - Setting up a new Cluster
Posted on 2014-10-09
I'm in the process of configuring the 1st node of what will become a 2-node (and possibly more in the future) Hyper-V 2012 R2 cluster. System Center VMM 2012 R2 is in place. Hardware is a HP BL460c Gen 8 blade (2-8core Xeon, 3 Emulex 554 2-port converged adapters) in a c3000 enclosure (8 slots, 4 interface modules). Chassis is fully populated with 4 HP B22 Cisco Nexus FEX Interface Modules each with 2-10GB links to 2 Cisco Nexus 5548 switches. SAN is an EMC VNX2 5400 with 2 Storage Processors (each with 2-10GB FCoE links to the Nexus).
Blade servers have 2 Ports on board 554flb 10GB converged adapters, and 2-2 Port 554m mezzanine converged adapters for a total of (6) 10GB interfaces per server.
Interface mapping to Chassis Network Modules is as follows:
On board Adapter 1 --> Module 1 Port 1
On board Adapter 2 --> Module 2 Port 1
Mezzine 1 Port 1 --> Module 1 Port 9
Mezzanine 1 Port 2 --> Module 2 Port 9
Mezzanine 2 Port 1 --> Module 3 Port 1 (Currently my FCoE Interface)
Mezzanine 2 Port 2 --> Module 4 Port 1 (Currently my FCoE Interface)
With both ports of Mezzanine 2 adapter as my FCoE, I'm left with 4 ports for networking.
My current thoughts/plans
Onboard Ports 1 & 2: Guest VM Networks (I'm not teaming so I can utilize SR-IOV).
Mezzanine 1 Ports 1&2: System Networks (CSV / Live Migration / Cluster Communications).
Mezzanine 2 Ports 1&2: Network Ports teamed as my Management Interface, FCoE ports as FCoE Fabric connection
I'm trying to figure out how I handle the System Networks (CSV/Live Migration/Cluster) - Team or no team. Do I loose performance/throughput by teaming? Any benefits to splitting these functions on to different VLANs and virtual adapters? SAN currently reports that their is high availability issues with both FCoE ports being on the same adapter, but that was the only way to split the FCoE across different network modules in the Chassis. I could split the FCoE across network modules, but this would but both FCoE and regular network traffic on the same network modules in the chassis and ultimately the uplinks to the switch.
Trying to make sure I do this right before I go into production with this. Please provide me with your feedback, suggestions, comments, etc. Thanks!
