MANAGEMENT METHODS IN SLA-AWARE DISTRIBUTED STORAGE SYSTEMS
Keywords:Service level agreements, mass storage systems, quality of service
AbstractTraditional data storage systems provide access to user’s data on the “best
effort” basis. While this paradigm is sufficient in many use cases it becomes
an obstacle for applications with Quality of Service (QoS) constraints. Service
Level Agreement (SLA) is a part of the contract agreed between the service
provider and the client and contains a set of well defined QoS requirements
regarding the provided service and the penalties applied in case of violations.
In the paper we propose a set of SLA parameters and QoS metrics relevant
to data storage processes and the management methods necessary for avoiding
SLA violations. A key assumption in the proposed approach is that the underlying
distributed storage system does not provide functionality for resource or
bandwidth reservation for a given client request.
