Server 2008 SP2 not R2 Failover
i inherited 2 sets of identical hardware server 2008 standard sp2 installed, neither '08 r2 consultants managing resources. each server running vmware2 server different virtual machines. host1 has production1 , dev1 virtual machines , host2 has production2 , dev2.
i need change configuration host1 , host2 have same configuration , 1 redundant other. (i don't care if it's hyper-v or vsphere in terms of knowledge, cost issue though) can create failover cluster automatically move vm's 1 set of hardware if fails without rebooting , without upgrading r2?
i able move vm's , forth perform maintenance right primary focus redundancy , fail over.
there network attached storage in form of mybookworld hard drive , willing iscsi san device host virtual machines.
i see lot of demos hyper-v live migration , it, question whether or not can implement solution without buying pair of r2 licenses hosts.
there 3rd party software solutions iscsi san starwind software me compare costs of upgrading r2 live migration feature.
thank in advance,
wes
hiya,
the general principles failover clustering scenario describe.
if hosta fails, ressourcers automatically started on hostb. - happend restart of virtual machines. - case or without r2.
what r2 live migration offers, possibility perform 0 downtime maintance. - planned downtime. not in case of unplanned downtime.
clustered ressources available long there node alive , has capacity clustered ressources.
the answer questions more directly:
1: yes possible achieve clustering without r2.
2: yes, switch happend automatically.
3: reboot virtual machines.
there quite alot of misconception how clustering virtual machines works. people believe long cluster ressources, setting 0 downtime solution application. are, providing redundant hardware setup. working on different layers, mixing up..
if talking database clustering, benefits go bit beyond hardware, because way databases work compared virtual machines.
