  • Patent number: 10296485
    Abstract: A method for RDMA optimized high availability for in-memory storing of data includes receiving RDMA key-value store write requests in a network adapter of a primary computing server directed to writing data to an in-memory key-value store of the primary computing server and performing RDMA write operations of the data by the network adapter of the primary computing server responsive to the RDMA key-value store write requests. The method also includes replicating the RDMA key-value store write requests to a network adapter of a secondary computing server, by the network adapter of the primary computing server. Finally, the method includes providing address translation data for the in-memory key-value store of the primary computing server from the network adapter of the primary computing server to the network adapter of the secondary computing server.

  • Publication number: 20180329860
    Abstract: A method, system and computer program product for remote direct memory access (RDMA) optimized producer-consumer message processing in a messaging hub is provided. The method includes initializing a shared memory region in memory of a host server hosting operation of a messaging hub. The initialization provides for a control portion and one or more data portions, the control portion storing an index to an available one of the data portions. The method also includes transmitting to a message producer an address of the shared memory region and receiving a message in one of the data portions of the shared memory region from the message producer by way of an RDMA write operation on a network interface of the host server. Finally, the method includes retrieving the message from the one of the data portions and processing the message in the messaging hub in response to the receipt of the message.

  • Patent number: 9471246
    Abstract: When a virtual machine writes to a page that is being shared across VMs, a share value is calculated to determine how different the page would be if the write command were implemented. If the share value is below a predefined threshold (meaning that the page would not be “too different”), then the page is not copied (as it would be in a standard copy-on-write operation). Instead, the difference between the contents of the pages is stored as a self-contained delta. The physical to machine memory map is updated to point to the delta, and the delta contains a pointer to the original page. When the VM needs to access the page that was stored as a delta, the delta and the page are then fetched from memory and the page is reconstructed.

  • Patent number: 9201697
    Abstract: Embodiments of the present invention provide a method, system and computer program product for collocating VMs based on memory sharing potential. In an embodiment of the invention, a VM co-location method has been claimed. The method includes selecting a VM from amongst different VMs for server colocation. The method additionally includes computing an individual shared memory factor for each of a set of the VMs with respect to the selected VM. The method yet further includes determining a VM amongst the VMs in the set associated with a highest computed shared memory factor. Finally, the method includes co-locating the determined VM with the selected VM in a single server.
