Abstract: Maximum throughput of a storage unit, and workload and latency values of the storage unit corresponding to a predefined fraction of the maximum throughput are estimated based on workloads and latencies that are monitored on the storage unit. The computed metrics are usable in a variety of different applications including admission control, storage load balancing, and enforcing quality of service in a shared storage environment.

Abstract: Embodiments associate software applications with computing resource containers based on placement rules. A placement rule indicates that a first software application is to be co-located with a second software application during execution of the first and second software applications and second placement rule indicates that the first software application is to be separated from the second software application when the second placement rule is violated by enforcing the first placement rule. The placement rule also indicates that the first software application is to be separated from the second software application during execution of the first and second software applications and the second placement rule indicates the first software application is to be co-located with the second software application when the second placement rule is violated by enforcing the first placement rule.

Abstract: Decentralized deduplication operations in a computer system employ a hash index that is a variant of a B+ tree to support both efficient sequential updates as well as efficient random updates. Sequential update is selected when deduplication is infrequently performed, such as on the order of days, and random update is selected when deduplication is performed more frequently, such as on the order of seconds. More frequent deduplication may be beneficial during periods when large amounts of temporary duplicate data are created, and the system may not have enough storage space to accommodate the temporary spike in demand.

Abstract: One or more embodiments of the present invention provide a technique for effectively managing virtualized computing systems with an unlimited number of hardware resources. Host systems included in a virtualized computer system are organized into a scalable, peer-to-peer (P2P) network in which host systems arrange themselves into a network overlay to communicate with one another. The network overlay enables the host systems to perform a variety of operations, which include dividing computing resources of the host systems among a plurality of virtual machines (VMs), load balancing VMs across the host systems, and performing an initial placement of a VM in one of the host systems.

Abstract: A shared input/output (IO) resource is managed in a decentralized manner. Each of multiple hosts having IO access to the shared resource, computes an average latency value that is normalized with respect to average IO request sizes, and stores the computed normalized latency value for later use. The normalized latency values thus computed and stored may be used for a variety of different applications, including enforcing a quality of service (QoS) policy that is applied to the hosts, detecting a condition known as an anomaly where a host that is not bound by a QoS policy accesses the shared resource at a rate that impacts the level of service received by the plurality of hosts that are bound by the QoS policy, and migrating workloads between storage arrays to achieve load balancing across the storage arrays.
Abstract translation: 共享的输入/输出（IO）资源以分散的方式进行管理。 具有对共享资源的IO访问权的多个主机中的每一个计算相对于平均IO请求大小进行归一化的平均延迟值，并且存储所计算的归一化等待时间值以备以后使用。 如此计算和存储的归一化等待时间值可以用于各种不同的应用，包括实施应用于主机的服务质量（QoS）策略，检测被称为异常的状况，其中不受 QoS策略以影响由QoS策略约束的多个主机接收的服务等级的速率访问共享资源，以及在存储阵列之间迁移工作负载以实现跨存储阵列的负载平衡。

Abstract: Memory pages that are allocated to a memory consumer and continue to be accessed by the memory consumer are included in a free list, so that they may be immediately allocated to another memory consumer as needed during the course of normal operation without preserving the original contents of the memory page. When a memory page in the free list is accessed to perform a read, a generation number associated with the memory page is compared with a stored copy. If the two match, the read is performed on the memory page. If the two do not match, the read is not performed on the memory page.

Abstract: Embodiments associate software applications with computing resource containers based on a placement rule and a selected failure correlation. A placement rule indicates that a first software application is to be co-located with a second software application during execution of the first and second software applications. The placement rule also indicates that the first software application is to be separated from the second software application during execution of the first and second software applications. Failure correlations are determined for a plurality of computing resources associated with the first software application. A computing resource with a lowest failure correlation is selected from the plurality of computing resources, and the second software application is associated with the selected computing resource despite the association violating the placement rule.

Abstract: An anomaly in a shared input/ouput (IO) resource that is accessed by a plurality hosts or clients is detected when a host that is not bound by any QoS policy presents large workloads to a shared IO resource that is also accessed by hosts or clients that are governed by QoS policy. The anomaly detection triggers a response from the hosts or clients as a way to protect against the effect of the anomaly. The response is an increase in window sizes. The window sizes of the hosts or clients may be increased to the maximum window size or in proportion to their QoS shares.
Abstract translation: 当未被任何QoS策略约束的主机向主机或客户端访问的共享IO资源提供大量工作负载时，会检测到由多个主机或客户机访问的共享输入/输出（IO）资源中的异常情况 由QoS策略管理。 异常检测触发主机或客户端的响应，作为防止异常的影响的一种方式。 响应是窗口大小的增加。 主机或客户端的窗口大小可以增加到最大窗口大小或者与它们的QoS份额成比例。
