Abstract: A network virtualization device receives a storage request from a compute instance executed by a host machine separate from the network virtualization device, the storage request comprising data to be stored. Responsive to receiving the storage request, the network virtualization device divides the data to be stored into a set of one or more data stripes. For a first data stripe in the set of data stripes, the network virtualization device determines, from a plurality of extent servers, a first extent server to which the first data stripe is to be sent for storing the first data stripe, transmits the first data stripe to the first extent server, wherein the first extent server stores the first data stipe to a first physical storage device, and receives, from the first extent server, an acknowledgement confirming that the first data stripe was stored.

Abstract: The present embodiments relate to throttling input/output (IO) processing tasks at a centralized node (e.g., a SmartNIC device) and implement multiple routing paths to prevent performance degradation in handling data patterns. For instance, the centralized node can implement a throttling system to assign portions of a number of input/output operations to be performed to a series of extent servers in a cloud infrastructure environment. The present embodiments also can implement multiple paths and/or multiple path groups to route the assigned portions of the I/O operations. For instance, the assigned portions of I/O operations can be routed to the extent servers via a first path of multiple paths. In the event of a failure of the first path, the assigned portions of I/O operations can be re-directed to a second path or another path in the path group.

Abstract: Techniques are disclosed for automated and dynamic compute resource allocation in an infrastructure-as-a-service (IaaS) environment. A system may determine a load threshold value corresponding to a maximum throughput of allocated resources and an active load of processing occurring at those resources. The threshold and load are compared to determine if throttling is occurring at the allocated resources. A specified range of permissible resource allocations is determined. Based on the range of permissible resource allocations, the threshold load value and the active load, the allocated resources may be modified. The modification may be a ramp-up of allocated resources to handle a throttling load or a ramp-down to reduce inefficient resource utilization and processing overhead. The ramp-up or ramp-down may be performed in periodic increments over periodic increments of time to reduce system stress and handle dynamically changing loads. A recommended permissible allocation range may be suggested.
