LACP bonding between servers
Posted on 2013-01-28
Experts Exchange Community,
I have a few XenServer and QuantaStor hosts that need redundant paths to a central switch. After the latest update to XenServer 6.1 the default of active-active source level balancing is not an option anymore - simply put, I can't afford any more mistakes with redundancy.
2 NICs in each server labeled Gb1 and Gb2
2 Dell 2808 labeled SW1 and SW2
Gb1 of each server connects to SW1, and Gb2 of each server connects to SW2
Then unconfigured ports 7,8 of SW1 and7,8 of SW2 trunk to unconfigured ports 1,2 and 3,4 respectively to a Cisco SRW2048 - the central switch.
Redundancy between XenServer and QuantaStor hosts is important because iSCSI is not fault-tolerant. I also have storage level replication between the primary and secondary iSCSI initiators for near continuous data protection, so having a highly available network is necessary to prevent these systems from breaking. I would like to simulate a switch failure by unplugging either of the Dell 2808 and not have interruption between the virtual machines and shared storage.
So, about this LACP - how do I enable and configure bonding between host server - Dell 2808 - Cisco SRW2048 in example listed above?
