Abstract

Embodiments included herein may be configured for managing one or more maximum transmission units (MTUs) for clustered and federated storage systems. Embodiments may include providing one or more heterogeneous storage clusters. A logical MTU may be configured on one or more leaf network interfaces of one or more networks. A physical network MTU may be configured on one or more intermediate network objects of the one or more networks. One or more physical network fabrics of the one or more networks may be managed. The physical network MTU may be managed via one of the one or more MTU domains. The physical network MTU may be reconfigured in response to determining the physical network MTU is outside of a pre-determined range.

First claim

What is claimed is:

1. A computer-implemented method for cluster-wide management of one or more maximum transmission units (MTUs) for clustered and federated storage systems comprising:
providing one or more heterogeneous storage clusters, wherein each of the one or more heterogeneous storage clusters includes a logical network MTU and a physical network MTU, wherein the logical network MTU and physical network MTU are separate from one another;
configuring the logical network MTU on one or more leaf network interfaces of one or more networks, wherein configuring the logical network MTU on the one or more leaf network interfaces of the one or more networks includes configuring the logical network MTU to be less than or equal to the physical network MTU;
configuring the physical network MTU on one or more intermediate network objects of the one or more networks, wherein configuring the physical network MTU occurs independently of configuring the logical network MTU;
managing one or more physical network fabrics of the one or more networks, wherein managing the one or more physical network fabrics occurs via one or more MTU domains;
managing the physical network MTU via one of the one or more MTU domains; and
reconfiguring the physical network MTU in response to determining the physical network MTU is outside of a pre-determined range.

2. The computer-implemented method of claim 1 , wherein the one or more heterogeneous storage clusters include one or more third-party components, wherein the one or more third-party components are embedded into the one or more heterogeneous storage clusters via containerization technologies by separating one or more of a portion of the logical network MTU and a portion of the physical network MTU.

3. The computer-implemented method of claim 1 , wherein configuring the physical network MTU on one or more intermediate network objects of the one or more networks allows for encapsulation of the one or more networks and use of one or more hyper-converged infrastructure (HCI) systems without affecting at least a portion of the first logical network and at least a portion of the second logical network.

4. The computer-implemented of claim 3 , wherein the one or more HCI systems include one or more of virtual switch managed network ports and network ports managed directly by a virtualized storage controller.

5. The computer-implemented method of claim 1 , wherein the one or more MTU domains include one or more of a uniform MTU domain (UMD) and a non-uniform MTU domain (NUMD).

6. The computer-implemented method of claim 1 , further comprising reconfiguring the logical network MTU in response to determining the logical network MTU is outside of a pre-determined range.

7. The computer-implemented method of claim 1 , wherein the one or more heterogeneous storage clusters are configured to support jumbo frames while avoiding overprovisioning of system buffers.

8. A computing system including a processor and a memory system configured to perform operations comprising:
providing one or more heterogeneous storage clusters, wherein each of the one or more heterogeneous storage clusters includes a logical network MTU and a physical network MTU, wherein the logical network MTU and physical network MTU are separate from one another;
configuring the logical network MTU on one or more leaf network interfaces of one or more networks, wherein configuring the logical network MTU on the one or more leaf network interfaces of the one or more networks includes configuring the logical network MTU to be less than or equal to the physical network MTU;
configuring the physical network MTU on one or more intermediate network objects of the one or more networks, wherein configuring the physical network MTU occurs independently of configuring the logical network MTU;
managing one or more physical network fabrics of the one or more networks, wherein managing the one or more physical network fabrics occurs via one or more MTU domains;
managing the physical network MTU via one of the one or more MTU domains; and
reconfiguring the physical network MTU in response to determining the physical network MTU is outside of a pre-determined range.

9. The computing system of claim 8 , wherein the one or more heterogeneous storage clusters include one or more third-party components, wherein the one or more third-party components are embedded into the one or more heterogeneous storage clusters via containerization technologies by separating one or more of a portion of the logical network MTU and a portion of the physical network MTU.

10. The computing system of claim 8 , wherein configuring the physical network MTU on one or more intermediate network objects of the one or more networks allows for encapsulation of the one or more networks and use of one or more hyper-converged infrastructure (HCI) systems without affecting at least a portion of the first logical network and at least a portion of the second logical network.

11. The computing system of claim 10 , wherein the one or more HCI systems include one or more of virtual switch managed network ports and network ports managed directly by a virtualized storage controller.

12. The computing system of claim 8 , wherein the one or more MTU domains include one or more of a uniform MTU domain (UMD) and a non-uniform MTU domain (NUMD).

13. The computing system of claim 8 , further comprising reconfiguring the logical network MTU in response to determining the logical network MTU is outside of a pre-determined range.

14. The computing system of claim 8 , wherein the one or more heterogeneous storage clusters are configured to support jumbo frames while avoiding overprovisioning of system buffers.

15. A computer program product comprising a non-transitory computer readable storage medium having a plurality of instructions stored thereon, which, when executed by a processor, cause the processor to perform operations including:
providing one or more heterogeneous storage clusters, wherein each of the one or more heterogeneous storage clusters includes a logical network MTU and a physical network MTU, wherein the logical network MTU and physical network MTU are separate from one another;
configuring the logical network MTU on one or more leaf network interfaces of one or more networks, wherein configuring the logical network MTU on the one or more leaf network interfaces of the one or more networks includes configuring the logical network MTU to be less than or equal to the physical network MTU;
