Storage tiering in cloud environment

摘要

A plurality of performance-based storage nodes and a plurality of capacity-based storage nodes of a data storage system in a network environment are allocated to one or more tiered resource pools such that the performance-based storage nodes and the capacity-based storage nodes allocated to each one of the one or more tiered resource pools are addressable via a given virtual address for each tiered resource pool. Access to the performance-based storage nodes and the capacity-based storage nodes in the one or more tiered resource pools by a plurality of compute nodes is managed transparent to the compute nodes via a given storage policy. At least portions of the compute nodes, the performance-based storage nodes, and the capacity-based storage nodes are operatively coupled via a plurality of network devices. One or more of the allocating and managing steps are automatically performed under control of at least one processing device.

1. A method, comprising:
allocating a plurality of performance-based storage nodes and a plurality of capacity-based storage nodes of a data storage system in a network environment to one or more tiered resource pools such that, for a given pool of the one or more tiered resource pools, the performance-based storage nodes and the capacity-based storage nodes allocated to the given pool are addressable via a given virtual address assigned to the given pool; and managing access of the performance-based storage nodes and the capacity-based storage nodes in the one or more tiered resource pools by a plurality of compute nodes, wherein access to the performance-based storage nodes and the capacity-based storage nodes is managed transparent to the compute nodes via a given storage policy; wherein at least portions of the compute nodes, the performance-based storage nodes, and the capacity-based storage nodes are operatively coupled via a plurality of network devices; wherein the managing step further comprises at least one of creating and migrating a storage volume in response to a request from one of the plurality of compute nodes; wherein creating the storage volume further comprises:
collecting network topology information from the plurality of network devices, and selecting an appropriate one of the performance-based storage nodes and the capacity-based storage nodes based at least in part on the given storage policy and the network topology information;communicating with the selected appropriate one of the performance-based storage nodes and the capacity-based storage nodes to allocate storage capacity thereon; andsending, to the compute node that requested creation of the storage volume, the given virtual address of the tiered resource pool in which the selected appropriate one of the performance-based storage nodes and the capacity-based storage nodes is allocated; and wherein one or more of the allocating and managing steps are automatically performed under control of at least one processing device.
