A system includes a storage subsystem and a first virtual machine to manage access of the storage subsystem. A second virtual machine is coupled by a virtual machine channel to the first virtual machine. The second virtual machine has software to issue a object-level input/output (I/O) request to the first virtual machine over the virtual machine channel to access data in the storage subsystem.

Providing object-level input/output requests between virtual machines to access a storage subsystem

A fault tolerant multiple network server system in which multiple servers concurrently act as back-up servers for each other even while they are providing their own server services to the system. Rather than having an unused server monitoring for failure of a primary server and taking over control, each is act upon the network, but when its partner should fail, it assumes control of these partner servers storage subsystem. In this way, processing power of both servers is available during normal operation, but they each provide back-up capability for the other.
