ABSTRACT:
A method, system and apparatus for storing data into two incompatibly formatted storage systems are provided. When a data is to be stored, it is first determined whether the data is to be stored into the two incompatibly formatted storage systems which are each being managed by a logical volume manager (LVM). If so, the data is forwarded to the two storage systems. In a particular embodiment, when the data is to be stored, one of the two LVMs determines whether the data is to be stored into the two storage systems. If so determined, the LVM that has made the determination passes a copy of the data to the other LVM. The two LVMs then ensure that the data is appropriately stored. When data is to be read from an incompatible storage system, the first LVM will request the data from the second LVM, when the data is received, the first LVM converts the data into an understandable format before the data is used.
