APPLICATION AWARE PROVISIONING FOR DISTRIBUTED SYSTEMS
Distributed storage systems are implemented with application aware provisioning. Methods include receiving a volume provision request to allocate data storage space for a storage volume implemented across a storage node cluster. Methods also include selecting a storage pool among a set of candidate storage pools for provisioning the storage volume. Selecting the storage pool includes using application aware provisioning rules.
1 . A method comprising:
receiving, at a processor of a server, a volume provision request to allocate data storage space for a storage volume implemented across a storage node cluster, the volume provision request corresponding to an application, the storage node cluster including a plurality of storage nodes, each storage node including one or more storage devices having storage space allocated for storing data associated with the storage volume; and
selecting a storage pool among a set of candidate storage pools for provisioning the storage volume, wherein selecting the storage pool includes using application aware provisioning rules.
2 . The method of claim 1 , wherein the application aware provisioning rules include a volume affinity rule or a volume anti-affinity rule.
3 . The method of claim 1 , wherein selecting a storage pool among a set of candidate storage pools for provisioning the storage volume includes using volume labels corresponding to pools and/or nodes.
4 . The method of claim 3 , wherein the volume labels identify the application.
5 . The method of claim 1 , wherein application aware provisioning rules depend on requirements or preferences of the application.
6 . The method of claim 1 , wherein selecting a storage pool among a set of candidate storage pools includes choosing the candidate storage pool with the highest volume rule score.
7 . The method of claim 1 , wherein a selected pool is assigned a new volume label if a volume label is not already assigned to the selected pool.
8 . A system comprising:
a storage node cluster, the storage node cluster including a plurality of storage nodes, each storage node including one or more storage devices having storage space allocated for storing data associated with a storage volume;
a network interface configured to receive a volume provision request to allocate data storage space for the storage volume implemented across the storage node cluster; and
a processor configured to:
select a storage pool among a set of candidate storage pools for provisioning the storage volume, wherein selecting the storage pool includes using application aware provisioning rules.
9 . The system of claim 8 , wherein the application aware provisioning rules include a volume affinity rule or a volume anti-affinity rule.
10 . The system of claim 8 , wherein selecting a storage pool among a set of candidate storage pools for provisioning the storage volume includes using volume labels corresponding to pools and/or nodes.
11 . The system of claim 10 , wherein the volume labels identify the application.
12 . The system of claim 8 , wherein application aware provisioning rules depend on requirements or preferences of the application.
13 . The system of claim 8 , wherein selecting a storage pool among a set of candidate storage pools includes choosing the candidate storage pool with the highest volume rule score.
14 . The system of claim 8 , wherein a selected pool is assigned a new volume label if a volume label is not already assigned to the selected pool.
15 . One or more non-transitory computer readable media having instructions stored thereon for performing a method, the method comprising:
receiving, at a processor of a server, a volume provision request to allocate data storage space for a storage volume implemented across a storage node cluster, the volume provision request corresponding to an application, the storage node cluster including a plurality of storage nodes, each storage node including one or more storage devices having storage space allocated for storing data associated with the storage volume; and
selecting a storage pool among a set of candidate storage pools for provisioning the storage volume, wherein selecting the storage pool includes using application aware provisioning rules.
16 . The one or more non-transitory computer readable media of claim 15 , wherein the application aware provisioning rules include a volume affinity rule or a volume anti-affinity rule.
17 . The one or more non-transitory computer readable media of claim 15 , wherein selecting a storage pool among a set of candidate storage pools for provisioning the storage volume includes using volume labels corresponding to pools and/or nodes.
18 . The one or more non-transitory computer readable media of claim 17 , wherein the volume labels identify the application.
19 . The one or more non-transitory computer readable media of claim 15 , wherein application aware provisioning rules depend on requirements or preferences of the application.
20 . The one or more non-transitory computer readable media of claim 15 , wherein selecting a storage pool among a set of candidate storage pools includes choosing the candidate storage pool with the highest volume rule score.
