Hyper-V 2012 - traditional network design vs. converged fabric in a small business enviroment
hello,
i in process of preparing our migration hyper-v 2012. @ moment little bit stuck on desision network layout chosse.
our future datacenter enviroment have 2 hyper-v clusters (1 5 node production , management systems , 1 2 node cluster dmz) , host 150 vms.
there no dynamic in physical infrastructure. systems planned have capacity needed on next 3 4 years.
converged fabric
i have done experiments converged fabric aproach (without havig vmm managing fabric) , ran several small issues.
i have had dublicate mac addresses because hosts had same local mac pool. , vnics hosts got served local mac pool.
the vmm dhcp switch extension has installed , activated before joining them cluster , managing them vmm.
all avoided using vmm manage fabric or manually managing local mac etc.
having vmm manage fabric require vmm run outside cluster on seperate server , effort in initial setup of vmm.
tradional setup
this straight forward, having 3 teams (host management, csv , live migration) host , 1 team vm traffic. without initial overhead setup fabric management vmm or doing hand.
vmm run inside cluster , manage virtual enviroment, have vmm 2008r2 doing now.
since small department 4 admins , 1 cio , have 500 workstations, 200 physical , virtual servers , 600 users manage little bit afraid "converged fabric" aproach add additional layer of complexity in setup , afterwards in diagnosis of problems may occur without giving real benefit.
i appreciate input on topic.

hi,
system center virtual machine management 2012 brings 1 of big changes in automated datacenter management notion of managing compute/network/storage fabric within datacenter. scvmm can automate hyper-v host deployments, storage , network setup , other elements.
the fabric in vmm made of hosts, host groups , library servers, networking , storage configuration. grouping hosts lets control placement weights, power , dynamic optimization, reserves , networks, , storage resources group. can aggregate 1 or more host groups cloud present users, either through web-based self-service portal or through locked-down version of vmm console.
windows server 2012 has better fabric support; may refer following articles configure test environment verify requirement.
