MULTILAYERED DATA STORAGE METHODS AND APPARATUS

摘要

A system, method, and apparatus for providing multilayered storage are disclosed. An example apparatus includes a virtual storage node and a data services node. The virtual storage node includes a first physical storage device including a first storage pool configured to have a first storage configuration and partitioned into individually addressable logical unit numbers (“LUs”) and a second storage pool configured to have a second storage configuration and partitioned into individually addressable LUs. The data services node includes a service pool configured to have a data services configuration specifying how data is stored to a logical volume from the virtual storage node, the logical volume including at least a first set of LUs from the first storage pool and second of LUs from the second storage pool.

1. An apparatus for providing hierarchical data storage comprising:
a virtual storage node including:
a first storage pool including a first physical storage device, the first storage pool configured to have a first storage configuration and partitioned into individually identifiable portions,a second storage pool including a second physical storage device, the second storage pool configured to have a second storage configuration and partitioned into individually identifiable portions,a Layer-2 Ethernet block storage target, anda file system and volume manager configured to manage the storage of data at the first physical storage device and the second physical storage device; and a data services node including:
a first service pool configured to have at least one striped or mirrored logical volume from the virtual storage node, the at least one logical volume including at least a first set of identifiable portions from the first storage pool and a first set of identifiable portions from the second storage pool,a second service pool configured to have at least one striped or mirrored second logical volume from the virtual storage node, the at least one second logical volume including a second set of identifiable portions from the first storage pool and a second set of identifiable portions from the second storage pool,an Layer-2 Ethernet block storage initiator communicatively coupled to the Layer-2 Ethernet block storage target of the virtual storage node, anda file system and volume manager configured to manage the storage of data at the first service pool and the second service pool.
