Abstract: Placement decisions can be made for data storage volumes based at least in part upon the requirements of the storage volumes and the capabilities of the types of hardware available to host those volumes. There may be multiple types of hardware capable of supporting a volume, and the placement can be biased to hardware capable of supporting fewer types of storage volumes in order to ensure sufficient capacity for the various types of storage volumes. A consistent level of performance can also be provided independent of the type of hardware utilized. Hardware can be selected to host a volume that is able to satisfy various volume requirements, and the operation can be adjusted to ensure that the volume requirements are satisfied over time.

Abstract: Systems and methods for an incast mitigation approach that first modifies network responses for content requests above a threshold size to be delayed according a response latency selected from an established latency range. Additionally, as incast characteristics are analyzed from network traffic, the volumes can selectively modify the individual established latency range to increase the latency range during periods of higher incast characteristics and to decrease the latency range when incast characteristics appear to be decreasing.
