摘要： A method and structure for a multi-workload storage system is disclosed that is adapted to determine if an additional workload can be placed on the storage system. The invention has storage elements and a proxy load generator connected to the storage elements. The proxy load generator is adapted to create a proxy workload based on an additional workload from a potential client. The proxy workload has a reduced duty cycle when compared to a duty cycle of said additional workload. A control server is connected to the storage elements and the proxy load generator. The control server applies the proxy workload to the storage elements during discontinuous time slices.

摘要： A method to optimize revenue realized under multiple service level agreements with multiple data storage clients is disclosed. The method provides an information storage and retrieval system. The method includes entering into (N) service level agreements to provide data storage services for (N) applications using the information storage and retrieval system, where each of the (N) service level agreements specifies an average maximum response time RTSLA. The method calculates for each value of (j), the value per unit throughput νj for the (j)th application, and then determines for each value of (j) the optimum data flow rate x(j)OPT. The method estimates, for each value of (j), a maximum data flow rate X(j)MAX that the (j)th application can utilize, and determines, for each value of (j), if x(j)OPT equals X(j)MAX. For each value of (j) where x(j)OPT does not equal X(j)MAX, the method delays execution of I/O requests from the (j)th application, such that the average response time for the (j)th application equals RT(j)SLA.
摘要翻译：公开了一种优化与多个数据存储客户端在多个服务级别协议下实现的收入的方法。该方法提供信息存储和检索系统。该方法包括：使用信息存储和检索系统（N）服务级别协议中的每一个指定平均最大响应时间RTSLA，进入（N）个服务级别协议来为（N）个应用提供数据存储服务。该方法针对（j）的每个值计算（j）应用的每单位吞吐量nuj的值，然后针对（j）的每个值确定最佳数据流速x（j）OPT。该方法针对（j）的每个值估计第（j）个应用可以利用的最大数据流量X（j）MAX，并且对于（j）的每个值确定如果x（j）OPT等于 X（j）MAX。对于（j）其中x（j）OPT不等于X（j）MAX的每个值，该方法延迟来自（j）应用的I / O请求的执行，使得（j） th应用等于RT（j）SLA。

摘要： Embodiments of the invention relate to dynamic power management of storage volumes and disk arrays in a storage subsystem to mitigate loss of performance resulting from the power management. The volumes and arrays are prioritized, and in real-time power is selectively reduced in response to both the prioritization and an energy savings goal. A feedback loop is provided to dynamically measure associated power gain based upon a lowering of power consumption, and device selection may be adjusted based upon received feedback.

摘要： Embodiments are provided for managing the system performance of resources performing tasks in response to task requests from tenants. In one aspect, a system that comprises at least one resource configured to perform at least one admitted task with an impact under the control of a computer system. The computer system provides services to more than one tenant. The computer system comprises a strategist configured to assess the impact of the admitted task to create a cost function vector containing multiple cost function specifications and a budget policy vector containing multiple budget policies and an actuator. The actuator receives the cost function vector and the budget policy vector from the strategist, receives a task request one of the more than one tenants, and calculates cost functions based upon the cost function vector to predict the impact of the task request on the resources for each of the task requests. The actuator throttles the task requests based upon the budget policies for the impact on the resources to create at least one of the admitted task performed by the resource and a delayed task request.

摘要： Data storage reliability is maintained in a write-back distributed data storage system including multiple nodes. Information is stored as a stripe including a collection of a data strips and associated parity strips, the stripe distributed across data and parity nodes. Each data node maintains the data strip holding a first copy of data, and each parity node maintains a parity strip holding a parity for the collection of data strips. A driver node initiates a full-stripe-write parity update protocol for maintaining parity coherency in conjunction with other nodes, to keep the relevant parity strips coherent. Parity is determined directly by computing parity strips for all data strips of a stripe. Any node may function as a driver node.

摘要： Embodiments of the invention are provided to enable fair and balanced allocation of control blocks to support processing of requests received from a client machine. The server is configured with tools to manage an account balance of control block availability for each service class. The account balance is periodically adjusted based upon usage, tenancy, deficits, and passage of time. Processing of one or more tasks in a service class is support when the credit value in the service class account is equal to or greater than the entry cost estimated for the request.
