摘要： Techniques are provided for storing data in a distributed storage system. A server stores an object according to a first storage policy in the distributed storage system that includes a plurality of storage nodes. Storing the object according to the first storage policy results in a first storage overhead for the object. The server receives a triggering event associated with the object, and the triggering event changes an attribute of the object. In response to the triggering event, the server identifies a second storage policy for the object. Storing the object according to the second storage policy results in a second storage overhead for the object different from the first storage overhead.

摘要： The disclosure provides a system, method and computer-readable storage device embodiments. Some embodiments can include an IPv6-centric distributed storage system. An example method includes receiving, at a computing device, a request to create metadata associated with an object from a client, creating the metadata based on the request and transmitting the metadata and an acknowledgment to the client, wherein the metadata contains an address in a storage system for each replica of the object and wherein the metadata can be used to write data to the storage system and read the data from the storage system. There is no file system layer between an application layer and a storage system layer.

摘要： This disclosure describes techniques for providing a distributed scalable architecture for Network Address Translation (NAT) systems with high availability and mitigations for flow breakage during failover events. The NAT servers may include functionality to serve as fast-path servers and/or slow-path servers. A fast-path server may include a NAT worker that includes a cache of NAT mappings to perform stateful network address translation and to forward packets with minimal latency. A slow-path server may include a mapping server that creates new NAT mappings, depreciates old ones, and answers NAT worker state requests. The NAT system may use virtual mapping servers (VMSs) running on primary physical servers with state duplicated VMSs on different physical failover servers. Additionally, the NAT servers may implement failover solutions for dynamically allocated routeable address/port pairs assigned to new sessions by assigning new outbound address/port pairs when a session starts and broadcasting pairing information.

摘要： Systems, methods, and computer-readable media for reducing distributed storage operation latency using segment routing. In some examples, a method can involve receiving, from a client, a message identifying an intent to store or retrieve data on a distributed storage environment, and sending to the client a segment routing (SR) list identifying storage node candidates for storing or retrieving the data. The method can involve steering a data request from the client through a path defined by the SR list based on a segment routing header (SRH) associated with the request, the SRH being configured to steer the request through the path until a storage node from the storage node candidates accepts the request. The method can further involve sending, to the client device, a response indicating that the storage node has accepted the request and storing or retrieving the data at the storage node that accepted the request.

摘要： Systems, methods, and computer-readable media for controlling container execution. In some examples, a system can determine whether a block of a container image used in running a container is present in local storage at a host. If the block of the container image is present in the local storage at the host, then the system can use the block in the local storage to run the container at the host. If the block of the container image is absent from the local storage at the host, the system can fetch the block of the container image for the host from a container image storage node where the container image resides in its entirety. The system can use the block of the container image fetched from the container image storage node to run the container.
