Hyper-V R2 Datacenter Cluster Licensing with Hyper-V Server

- January 21, 2010

hi,

i have 10 blade servers which starting come end of their life. purchased 7 blades in 2004 and 3 more in 2007 which still have support another 18 months.

i have run msmap utility , says can virtualize all 10 blades , place 9 of 10 vms on hosta. the left on vm placed on hostb. doesn't give me failover capability i need run 3rd server (hostc).

from understand must license each server maximum number of virtual oss run.

does mean can run 2008 r2 dc on hosta 2008 r2 hyper-v server on hostb (the guest vm running copy of 2008 r2 std which has already been purchased under e.a.) , 2008 r2 dc on failover server?

this mean that in case of hosta failing 9 vms migrate hostc. in event of hostb failing single vm migrate hostc.

this mean require 4 processor license 2008 r2 dc instead of 6 processor license. when hardware replaced looking replace 3 node cluster 2 node cluster. not want have pay extra 2 processors licensing when, ultimately, of no use to me within 18 months time.

thanks in advance.

james.

>> correct this.

>> honest, can’t concern through above description. please check following post see whether helpful.

by way, if want build test environment, can put domain controller on hyper-v host machine or within vm running on hyper-v. however, if in production environment, microsoft recommends locate critical server roles on domain controllers installed directly on physical hardware. these include global catalog servers, domain name system (dns) servers, flexible single master operations (fsmo) roles , replication bridgeheads.
