Abstract

Methods and apparatus to provide, in a cloud infrastructure environment a shared storage service with only storage, wherein the storage can be shared with other managed services. The storage is exposed to hosts with commands to the storage, networking, and compute resources.

Claims

1. A method, comprising:

receiving a user request via a service offering for a shared storage service in a cloud infrastructure environment having a compute layer, a network layer, a storage layer, and management layer;

creating a storage-only shared storage service having a first storage volume, wherein the first storage volume has a storage tiering policy, a tier, a storage type and a storage pool identifier, and wherein the storage tiering policy includes an availability indicator;

attaching the shared storage service to existing first and second services, wherein the first and second services each include network, compute and storage resources;

sending commands to the network, compute and storage resources to expose the storage volume to hosts in the environment; and

adopting the storage-only shared service into the management layer by;

selecting hosts from which the storage-only shared service may be derived;

collecting unique identifiers for the selected hosts;

discovering block storage volumes;

discovering SAN paths for the block storage volumes and NFS storage paths; and

collecting exposed ones of the block storage volumes for the selected hosts.

2. The method according to claim 1, further including detaching the shared storage service from the first and second services.

3. The method according to claim 1, further including adding a second storage volume to the shared storage service.

4. The method according to claim 1, further including isolating the storage resources of the first service from the first storage volume of the shared storage service.

5. The method according to claim 1, wherein properties of the first storage volume are defined by a service offering that includes the shared storage service.

6. The method according to claim 5, wherein a type of storage for the first storage volume corresponds to the service offering.

7. The method according to claim 1, wherein the storage tiering policy further includes an in use indicator.

8. The method according to claim 1, wherein the tier comprises characteristics including free capacity, RAID level, and storage pools.

9. The method according to claim 1, further including identifying clusters of hosts based upon presence of the block storage volumes shared by ones of the hosts.

10. An article, comprising:

a non-transitory computer-readable medium containing stored instructions that enable a machine to;

receive a user request via a service offering for a shared storage service in a cloud infrastructure environment having a compute layer, a network layer, a storage layer, and management layer;

create a storage-only shared storage service having a first storage volume, wherein the first storage volume has a storage tiering policy, a tier, a storage type and a storage pool identifier, and wherein the storage tiering policy includes an availability indicator;

attach the shared storage service to existing first and second services, wherein the first and second services each include network, compute and storage resources;

send commands to the network, compute and storage resources to expose the storage volume to hosts in the environment; and

adopt the storage-only shared service into the management layer by;

selecting hosts from which the storage-only shared service may be derived;

collecting unique identifiers for the selected hosts;

discovering block storage volumes;

discovering SAN paths for the block storage volumes and NFS storage paths; and

collecting exposed ones of the block storage volumes for the selected hosts.

11. The article according to claim 10, further including instructions for detaching the shared storage service from the first and second services.

12. The article according to claim 10, further including adding a second storage volume to the shared storage service.

13. The article according to claim 10, further including applying storage tiering to the first storage volume.

14. The article according to claim 10, further including isolating the storage resources of the first service from the first storage volume of the shared storage service.

15. The article according to claim 10, wherein properties of the first storage volume are defined by a service offering that includes the shared storage service.

16. The article according to claim 15, wherein a type of storage for the first storage volume corresponds to the service offering.

17. A cloud infrastructure system having a compute layer, a network layer, a storage layer, and management layer, comprising

a processor;

and

a memory coupled to the processor, the processor configured to;

receive a user request via a service offering for a shared storage service in the cloud infrastructure system;

create a storage-only shared storage service having a first storage volume, wherein the first storage volume has a storage tiering policy, a tier, a storage type and a storage pool identifier, and wherein the storage tiering policy includes an availability indicator;

attach the shared storage service to existing first and second services, wherein the first and second services each include network, compute and storage resources;

send commands to the network, compute and storage resources to expose the storage volume to hosts in the environment; and

adopt the storage-only shared service into the management layer by;

selecting hosts from which the storage-only shared service may be derived;

collecting unique identifiers for the selected hosts;

discovering block storage volumes;

discovering SAN paths for the block storage volumes and NFS storage paths; and

collecting exposed ones of the block storage volumes for the selected hosts.

18. The system according to claim 17, wherein the processor is further configured to detach the shared storage service from the first and second services.

19. The system according to claim 17, wherein the processor is further configured to add a second storage volume to the shared storage service.
