The use of multiple ips on a single network card can usually only work when they are a clustered resource with the failover cluster manager. In each nic you add a single network ip address with or without a gateway in the operating system. You can add a cluster resource of type ip address to setup a access point for the resource. I use this for things like a ...

lvs, openais are both open source. The problem is to use clusters and/or load-balancers properly. That includes deep technical knowledge about what you actually want.

After further investigation it seems to me that 2012 either defaults to or is hard-coded to "persistent mode" and they've disabled changing the value with the GUI.

You should really look at Microsoft DFS to do what you're talking about. It provides a way to abstract the physical location of data by bringing everything together in one place. So, for example you would have: 2 cluster nodes (FSCL1, FSCL2) 2 clustered file services (FS1, FS2), running on the above nodes 2 domain-based DFS namespaces (HOMES, SHARES), ...

Here has some PowerShell commands to do this, have you seen/tried these at all? http://blog.crayon.no/blogs/janegil/archive/2011/06/03/enable_2D00_persistent_2D00_mode_2D00_for_2D00_cluster_2D00_resource_2D00_groups_2D00_using_2D00_the_2D00_powershell_2D00_failover_2D00_clustering_2D00_module.aspx

Not much to add here since StarWind and HP VSA are already mentioned! Both products provide great value and do exactly what you're trying to accomplish. Keep in mind, you won't be able to shuffle the VMs back to local storage if it's already provisioned as storage pool for either HP VSA or StarWind. However, StarWind's storage is always available in ...

StarWind Virtual SAN is pretty much everything you need. Unlike VM-running home-brewed solution GregL was mentioning this particular one is 100% native to Hyper-V as it's Windows app: simple to install and no VM patching mess. + performance. If you're fine with VMs take a look @ HP StoreVirtual VSA. It would be 1TB limited in capacity for their free version ...

I would think your only way to accomplish this would be to setup your own, home-grown version, of vSAN with a locally hosted "controllers". Something like this, or a set of clustered FreeNAS/OpenFiler instances running DRBD should do the trick. I wouldn't rely on it for primary storage purposes, but it might do OK in a pinch when you need to do disruptive ...

Failover clusters require shared storage. Without it, if a machine dies, the data on them is inaccessible and there's no way to failover without the data. I don't believe there is any built in fault tolerant method of using the local drives. For clustered virtual machines, you need shared storage, and internal drives don't qualify. What you can do, ...

Looking at a pair of hardware appliances will certainly be a good start. You can do it in software, but you may find that your networking team (if you have one) may object to you performing network-related functions on non-approved equipment -- this can limit failover technologies. Apache (httpd) itself doesn't know anything about clustering httpd ...

The world is full of applications that were never designed with clustering in mind and terrible things happen when you try to run multiple instances of the application concurrently. But the application might be critical enough that having a standby server is a viable solution to meet your availability requirements. Clustering software will typically ensure ...

Virtualization doesnt really gain you much here - that is for making one big machine act like several small ones. You want a bunch of big machines. Splitting a host's physical storage across a bunch of virtual machines will just cause you headaches. It also would make it harder to use redundancy in clustered filesystems since you need to make sure they ...

This is probably because your system driver doesn't allow you to connect to the zookeeper which is running on some other host. Just add the host to your /etc/hosts. From windows, go to file C:\Windows\System32\drivers\etc\hosts and add the below line: # 192.168.0.2 rhino.acme.com # source server 192.168.0.2 --> ip of the zookeeper ...

FarmWarDeployer can be configured at host level cluster only. Cluster settings move into the <Host>...</Host>. It work for me. https://tomcat.apache.org/tomcat-7.0-doc/config/cluster-deployer.html

I have ignored, or rather forgot, the fact that sql user accounts on servers had different sid which in fact was the source of the issue.
