摘要： A system includes a number of hard disk drives and a controller. Each hard disk drive is selected from a number of different hard disk drive types. Each hard disk drive type has a different speed at which the hard disk drives of the hard disk drive type rotate to read and write data. At least one of the hard disk drives is of a different hard disk drive type than at least one other of the hard disk drives. The controller, responsive to a request to write particular data to the hard disk drives, is to select a given hard disk drive of the hard disk drives based on a type of the particular data, and is to write the particular data to the given hard disk drive.

摘要： A method comprises determining a flexible limit on an amount of resource usage by a driver domain on behalf of a given virtual machine (VM). The method further comprises controlling the resource usage by the driver domain on behalf of the given VM so as not to exceed the flexible limit except under a permitted condition. In certain embodiments the resource usage by the driver domain on behalf of the given VM is controlled so as not to exceed the flexible limit except when a slack share of resource usage is available to the driver domain. Such a slack share of resource usage is a share of resource usage allocated to the driver domain that will not otherwise be used on behalf of another VM.

摘要： A performance model for a collection of jobs that make up a program is used to calculate a performance parameter based on a number of map tasks in the jobs, a number of reduce tasks in the jobs, and an allocation of resources, where the jobs include the map tasks and the reduce tasks, the map tasks producing intermediate results based on segments of input data, and the reduce tasks producing an output based on the intermediate results. The performance model considers overlap of concurrent jobs. Using a value of the performance parameter calculated by the performance model, a particular allocation of resources is determined to assign to the jobs of the program to meet a performance goal of the program.

摘要： A system, and a corresponding method enabled by and implemented on that system, automatically calculates and compares costs for hosting workloads in virtualized or non-virtualized platforms. The system allows a service user (i.e., a customer) to decide how best to have workloads hosted by apportioning costs that are least sensitive to workload placement decisions and by providing robust and repeatable cost estimates. The system compares the costs of hosting a workload in virtualized and non-virtualized environments; separates workloads into categories including those that should be virtualized and those that should not, and determines the amount of physical resources to cost-effectively host a set of workloads.
摘要翻译：在该系统上启用和实施的系统以及相应的方法自动计算和比较虚拟化或非虚拟化平台中托管工作负载的成本。该系统允许服务用户（即，客户）通过分摊对工作负载布局决定最不敏感的成本并通过提供鲁棒且可重复的成本估计来决定如何最好地托管工作负载。系统比较虚拟化和非虚拟化环境中托管工作负载的成本; 将工作负载分成包括那些应该被虚拟化的类别，而不是那些应该被虚拟化的那些，并且确定物理资源的数量以经济有效地托管一组工作负载。
