Systems and methods to improve read/write performance in object storage applications

1. A method to integrate Software-Defined Networking (SDN) with an object storage client to enable object-writes in an object storage cluster, the method comprising:

responsive to receiving a write request from a client, determining a flow map comprising a group of objects selected to store data associated with the write request;

sending Object Storage Device (OSD)-related information that is associated with or comprises the flow map to an SDN controller; and

generating flow entries, using the SDN controller, to control traffic in a network, the SDN controller generating the flow entries, comprising one or more prioritizations for one or more flows that result, at least in part, by executing the write request, using at least the flow map and one or more predictions of traffic in the network that result, at least in part, by executing the write request.

2. The method according to claim 1 , further comprising, in response to receiving an object from an object storage client, mapping the object to the group of objects.

3. The method according to claim 1 , wherein at least one of the one or more prioritizations of the flow entries comprises one or more Quality of Service (QoS) policies associated with real-time flow-information.

4. The method according to claim 1 , wherein generating flow entries comprises mapping the one or more rules from the flow map to the flow entries.

5. The method according to claim 1 , wherein at least one of the one or more prioritizations of the flow entries comprises prioritizing a connection between at least one of a first group comprising a client and a primary OSD and a second group comprising the primary OSD and a secondary OSD.

6. The method according to claim 1 , further comprising (primary OSD) replicating the object by writing the object into the secondary OSD.

7. The method according to claim 1 , further comprising in response to receiving written flows the SDN controller sending delete flows to one or more switches.

8. The method according to claim 1 , wherein the OSD-related information comprises write flows.

9. The method according to claim 1 , wherein the flow map identifies a primary OSD and comprises one or more rules.

10. A system to enable dynamic configuration of a network, the system comprising:

an object storage client, operating on a computing system comprising one or more processors and communicatively coupled to receive Object Storage Device (OSD)-related information about distributed storage in a network, the object storage client configured to:

determine a flow map based on groups of objects in the distributed storage that are intended to receive data related to a data request; and

send Object Storage Device (OSD)-related information associated with or comprising the flow map to an SDN controller that generates flow entries, comprising one or more prioritizations for one or more flows that result at least in part by executing the data request using at least the flow map and one or more predictions of traffic in the network that result, at least in part, by executing the data request, to control the network, at least in part, using the flow entries.

11. The system according to claim 10 , wherein the object storage client is a Ceph client.

12. The system according to claim 10 , wherein the groups of objects are located in placement groups.

13. The system according to claim 10 , further comprising a primary OSD to replicate itself by writing the groups of objects into a secondary OSD.

14. The system according to claim 10 , wherein the object storage client is configured to send at least one of a delete flow map and a flow map comprising written flows to the SDN controller.

15. A system to enable integration of distributed storage with Software-Defined Networking (SDN), the system comprising:

an object storage client operating on a computing system comprising one or more processors and communicatively coupled to receive information about distributed storage in a network and configured to determine a flow map based on a group of objects in the distributed storage and a data request; and

an SDN controller, operating on a server system comprising one or more processors and communicatively coupled to at least one network interfacing device to control network traffic, configured to:

receive the flow map; and

using at least the flow map and one or more predictions of traffic in the network that result, at least in part, by executing the data request, generate flow entries, comprising one or more prioritizations for one or more data flows that result, at least in part, by executing the data request, to control traffic in the network using the flow entries.

16. The system according to claim 15 , wherein the SDN controller is located in a server-switch architecture.

17. The system according to claim 15 , wherein the SDN controller is configured to generate Quality of Service (QoS) policies associated with real-time flow-information to prioritize one or more connections.

18. The system according to claim 17 , wherein generating the QoS policies comprises mapping one or more rules from the flow map to the flow entries.

19. The system according to claim 18 , wherein the one or more rules are based on one of a source destination IP address, a destination IP address, a port number, an ingress switch port, a VLAN, and a VxLAN.

20. The system according to claim 18 , wherein mapping the one or more rules comprises inserting Access Control List (ACL) rules into a network interface controller card, the ACL rules being associated with a connection between at least one of a first group comprising a client and a primary OSD and a second group comprising the primary OSD and a secondary OSD.
