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 ...

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, ...

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), ...

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.

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 ...

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 ...

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 ...
