Abstract

Examples may include techniques to provide redundant array of independent disks (RAID) services using a shared pool of configurable computing resources. Information for a data service being provided using the shared pool of configurable computing resources may be received. Logical servers hosting logical volume managers (LVMs) may be composed from at least a portion of the shared pool of configurable computing resources. In some examples, the hosted LVMs are capable of each providing a RAID service based, at least in part, on the received information for the data service.

Claims

1. An apparatus comprising:

circuitry;

a receive component for execution by the circuitry to receive information for a data service being provided using a shared pool of configurable computing resources, the data service including redundant array of independent disks (RAID) services; and

a composition component for execution by the circuitry to compose a plurality of logical servers such that each logical server includes at least a portion of the shared pool of configurable computing resources, the plurality of logical servers capable of separately hosting a logical volume manager (LVM) capable of providing a separate RAID service using at least a portion of the shared pool of configurable computing resources included with a respective logical server that hosts each LVM, the separate RAID service provided by each LVM based, at least in part, on the received information.

2. The apparatus of claim 1, the received information for the data service including a service level agreement or service level objective for one or more customers of the data service.

3. The apparatus of claim 1, comprising the composition component to configure at least some of the LVMs such that a first LVM capable of providing a first RAID service is arranged to be a hot spare for a second LVM currently providing the first RAID service.

4. The apparatus of claim 1, the composition component to compose the plurality of logical servers comprises the composition component to configure at least some of the logical servers such that a first logical server hosting a first LVM capable of providing a first RAID service is arranged to be a hot spare for a second logical server hosting a second LVM currently providing the first RAID service.

5. The apparatus of claim 1, comprising the composition component to configure at least some of the LVMs to provide RAID services having different redundancy characteristics such that a first LVM provides a first RAID service having a first volume expansion capability and a second LVM provides a second RAID service having a second, different volume expansion capability.

6. The apparatus of claim 1, comprising:

a hierarchy component for execution by the circuitry to maintain a data path between each LVM such that a network hierarchy is established to enable failover between at least a first LVM arranged to provide a first RAID service to a second LVM also arranged to provide the first RAID service if a logical server hosting the first LVM fails or is no longer capable of supporting the first LVM.

7. The apparatus of claim 6, the hierarchy component to also maintain the data path using the network hierarchy to reconfigure the data path between the first LVM and the second LVM responsive to a failure of a first data link between the first and second LVMs.

8. The apparatus of claim 7, comprising the failure of the logical server hosting the first LVM or the failure of the first data link is based on a reliability, availability and serviceability (RAS) event defined, at least in part, in the received information for the data service.

9. The apparatus of claim 6, the data path comprising a transmission control protocol/internet protocol (TCP/IP) based network data path or a fabric based network data path.

10. The apparatus of claim 1, the shared pool of configurable computing resources comprising disaggregate physical elements including central processing units, memory devices, storage devices, network input/output devices or network switches.

11. The apparatus of claim 1, comprising a digital display coupled to the circuitry to present a user interface view.

12. A method comprising:

receiving, at a processor circuit, information for a data service being provided using a shared pool of configurable computing resources, the data service including redundant array of independent disks (RAID) services; and

composing a plurality of logical servers such that each logical server includes at least a portion of the shared pool of configurable computing resources, the plurality of logical servers capable of separately hosting a logical volume manager (LVM) capable of providing a separate RAID service using at least a portion of the shared pool of configurable computing resources included with a respective logical server that hosts each LVM, the separate RAID service provided by each LVM based, at least in part, on the received information.

13. The method of claim 12, the received information for the data service including a service level agreement or service level objective for one or more customers of the data service.

14. The method of claim 12, comprising:

maintaining a data path between each LVM such that a network hierarchy is established to enable failover between at least a first LVM arranged to provide a first RAID service to a second LVM also arranged to provide the first RAID service if a logical server hosting the first LVM fails or is no longer capable of supporting the first LVM.

15. The method of claim 14, maintaining the data path using the network hierarchy to reconfigure the data path between the first LVM and the second LVM responsive to a failure of a first data link between the first and second LVMs.

16. The method of claim 15, comprising the failure of the logical server hosting the first LVM or the failure of the first data link is based on a reliability, availability and serviceability (RAS) event defined, at least in part, in the received information for the data service.

17. The method of claim 12, the shared pool of configurable computing resources comprising disaggregate physical elements including central processing units, memory devices, storage devices, network input/output devices or network switches.

18. At least one machine readable medium comprising a plurality of instructions that in response to being executed by system cause the system to:
