Looks like it does. http://blogs.technet.com/b/canitpro/archive/2013/08/20/step-by-step-creating-a-sql-server-2012-alwayson-availability-group.aspx All editions of Server 2012 allow clustering.
LiveMigration and virtual machine failover are two different things. LiveMigration is for planned migrations of a virtual machine from one Hyper-V host to another with no downtime of the virtual machine or it's services and applications. Failover of a virtual machine occurs when the host it is running on fails and the cluster restarts the virtual machine on ...
Just have your development server connect using normal replication, not join the cluster. Standard replication is one way (unless you set it up on both sides). Your dev server would pull the binlogs from the master it's slaving from. That's all the communication that would happen between the dev instance and your cluster. I don't think there would be an ...
sysctl -w net.ipv4.conf.all.arp_ignore=1 1 - reply only if the target IP address is local address configured on the incoming interface sysctl -w net.ipv4.conf.all.arp_announce=2 2 - Always use the best local address for this target. In this mode we ignore the source address in the IP packet and try to select local address that we prefer for talks with ...
If you can spare the disk space, build an archive mirror with debmirror on an internet-connected machine, then move it to the non-connected network. You'll need about 70GB of space for a full mirror of Precise (12.04) only. A full ubuntu mirror (all versions, releases, CDs etc) is about 700GB. You'll need to do some other stuff too, but there's really ...
Yes - use a configuration management tool like Puppet or Chef - store your config in version control, then the tool can handle distributing it to both servers and doing the graceful restart of the service. It's probably overkill when you're looking at just this task, but it will be useful throughout your environment.
You're on the right way. You definitely should use ldap for authentication of all your users except system users (root, daemon etc...). That way you get consistend uid's/gid's which is vital for the next step: NFS. Either mount /home via NFS from a central host, or use automount to mount individual homedirs upon access/login.
