A method, non-transitory computer readable medium and local storage node computing device that establishes a first connection between a first endpoint in a kernel of an operating system and a second endpoint. A proxy application in a user space is invoked and a second connection is established from the operating system kernel to the proxy application. The proxy application is linked to a secure protocol implementation. Handshake messages are proxied between the second endpoint and the proxy application using the first and second connections. Security parameters for the first connection and determined from the handshake messages are sent from the proxy application to the operating system kernel via the second connection. Data is exchanged between the first endpoint in the operating system kernel and the second endpoint using the first connection and the security parameters.

Methods for facilitating secure connections for an operating system kernel and devices thereof

Exemplary embodiments provide methods, mediums, and systems for efficiently moving data between cluster nodes. Upon receiving a request to read or write data at a first cluster node that is in communication with a client, the first node effects the transfer to or from a second cluster node. The transfer is carried out using a combination of remote data memory access ('RDMA'), or a similar technique that bypasses a part of the network stack, and transport control protocol ('TCP'), or a similar technique that does not bypass a part of the network stack. The data is transferred using RDMA, while certain control messages are sent using TCP. By combining RDMA content transfers and TCP control messages, data transfers can be carried out faster, more efficiently, and with less processing overhead. Other embodiments are described and claimed.
