摘要： A system and method for providing quality of service (QoS) for clients running on host computers to access a common resource uses a resource pool module and a local scheduler in at least one of the host computers. The resource pool module operates to compute an entitlement of each client for the common resource based on a current capacity for the common resource and demands of the clients for the common resource. In addition, the resource pool module operates to assign a portion of the computed current capacity for the common resource to a particular host computer using the computed entitlement of each client running on the particular host computer. The local scheduler operates to allocate the portion of the computed current capacity among the clients running on the particular host computer.

摘要： Two shared data structures are maintained in a storage unit for coordinating statistic collection among multiple hosts that share the storage unit. The first data structure stores information about the number of hosts that possess slots within the second data structure and identifying information about the slots. The second data structure maintains statistics of each of the multiple hosts. By using this first data structure, hosts can be added to and deleted from the second data structure in an organized manner.

摘要： A method for providing quality of service to a plurality of hosts accessing a common resource is described. The common resource may be a middle-tier or back-end server. A client IO request is received at one host of the plurality of hosts from one of a plurality clients executing as software entities on respective hosts. The host determines whether an issue queue is full. The IO request is issued to the common resource when the issue queue is not full. A current average latency observed at the host and an adjusted window size is calculated, based at least in part on the current average latency. The issue queue is resized to correspond with the adjusted window size.

摘要： A method for managing an amount of IO requests transmitted from a host computer to a storage system is described. A current latency value of an IO request most recently removed from an issue queue maintained by the host computer in order to transmit IO requests from the host computer to the storage system is periodically determined. An average latency value is the calculated based on the current latency value and a size limit of the issue queue is adjusted based in part on the average latency value. Upon receiving an IO request from one of a plurality of client applications running on the host computer, it can then be determined whether a number of pending IO requests in the issue queue has reached the size limit and the IO request can be transmitted to the issue queue if the number of pending IO request falls within the size limit.

摘要： Embodiments perform centralized input/output (I/O) path selection for hosts accessing storage devices in distributed resource sharing environments. The path selection accommodates loads along the paths through the fabric and at the storage devices. Topology changes may also be identified and automatically initiated. Some embodiments contemplate the hosts executing a plurality of virtual machines (VMs) accessing logical unit numbers (LUNs) in a storage area network (SAN).

摘要： To schedule workloads of requesters of a shared storage resource, a scheduler specifies relative fairness for the requesters of the shared storage resource. In response to the workloads of the requesters, the scheduler modifies performance of the scheduler to deviate from the specified relative fairness to improve input/output (I/O) efficiency in processing the workloads at the shared storage resource.
