Data Center High Availability Clusters Teaming Features (IN INTEL ANS CONTEXT – SEE INTEL LINK) Teaming Features include Failover protection, increased bandwidth throughput aggregation, and balancing of traffic among team members. Teaming Modes are AFT, SFT, ALB, Receive Load Balancing (RLB), SLA, and IEEE 802.3ad Dynamic Link Aggregation. Features available by using Intels Advanced Networking Software (ANS) include: Fault Tolerance Uses one or more secondary adapters to take over for the primary adapter should the first adapter, its cabling or the link partner fail. Designed to ensure server availability to the network. Link Aggregation The combining of multiple adapters into a single channel to provide greater bandwidth. Bandwidth increase is only available when connecting to multiple destination addresses. ALB mode provides aggregation for transmission only while RLB, SLA, and IEEE 802.3ad dynamic link aggregation modes provide aggregation in both directions. Link aggregation modes requires switch support, while ALB and RLB modes can be used with any switch. Load Balancing The distribution of the transmission and reception load the among aggregated network adapters. An intelligent adaptive agent in the ANS driver repeatedly analyzes the traffic flow from the server and distributes the packets based on destination addresses. (In IEEE 802.3ad modes the switch provides load balancing on incoming packets.) Note: Load Balancing in ALB mode can only occur on Layer 3 routed protocols (IP and NCP IPX). Load Balancing in RLB mode can only occur for TCP/IP. Multicasts, broadcasts, and non-routed protocols are transmitted only over the primary adapter.

  • 31. Service Strategy provides advice and guidance on designing, developing andimplementing service management - both as an operational capability withinan organisation but also how to use that capability as a strategic asset. It triesto ensure that consideration is given as to why a particular activity is to beperformed - before an organisation begins to think about how it will beperformed.The core process in Service Strategy involves:Define the marketDevelop the offeringsDevelop strategic assetsPrepare for execution
  • 32. Service Design contains discussions on the roles, responsibilities and activities involved within the ServiceDesign stage and also considers the impact of processes on the service designs produced. Service Design alsodescribes the major processes involved within these design activities, including:• Service Catalogue Management• Service Level Management• Capacity Management• Availability Management• IT Service Continuity Management• Information Security Management• Supplier Management.
  • 33. Service Transition is the controlled building, testing and deployment of a new or changed service which enables theplanning, tracking and checking of progress against requirements at every stage through the service transition.The Service Transition stage of the lifecycle provides guidance on ensuring that the introduction, deployment, transferand decommissioning of new or changed services is consistently well managed. Service Transition ensures that thetransition processes are streamlined, effective and efficient so that the risks relating to the service in transition areminimised. Successful Service Transition depends on an effective understanding and application of the ChangeManagement process as well as quality assurance, risk management and effective programme and projectmanagement.The Service Transition stage of the lifecycle receives input from the Service Design stage and provides output to theService Operation stage.The main goals and objectives for Service Transition include:•Assisting organisations wishing to plan and manage service changes and deploy service releases into the productionenvironment successfully.•Setting customer expectations on how the performance and use of the new or changed services can be used to enablebusiness change.•Enabling the business change project or customer to integrate a release into their business processes and services.•Reducing variations in the predicted and actual performance of the transitioned services.•Reducing known errors and minimising the risks from transitioning the new or changed services into production.•Planning and managing resources to successfully establish a new or changed service into production within thepredicted cost, quality and time estimates.•Ensuring minimal unpredicted impact on the production services, operations and support organisation.•Increasing the customer, user and service management staff satisfaction with the service transition practices.•Providing a consistent and rigorous framework for evaluating the service capability and risk profile before a new orchanged service is released or deployed.•Establishing and maintaining the integrity of all identified service assets and configurations as they evolve throughthe service transition stage.•Providing efficient repeatable build and installation mechanisms that can be used to deploy releases to the test andproduction environments and re-built if required to restore service.
  • 34. Service Operation is responsible for all aspects of managing the day-to-day operation of IT services, ensuring that processes and activities areoperated (and continue to be operated) on a ‘business as usual’ basis. Its key purpose is to coordinate and perform the processes and activitiesthat support the delivery of the IT services at the levels defined in the relevant Service Level Agreements.The scope of Service Operation covers the IT services, the service management processes, the underpinning technology used to deliver thoseservices - and the people used to manage all of these aspects.Service Operation can be optimised in two different ways:Long term incremental improvement - monitoring performance over a period of time, analysing whether improvement actions are required, and thenimplementing those improvements via the Continual Service Improvement bookShort term improvement activities - these are smaller actions, such as tuning, workload balancing, training, etc.Service Operation is supported by a number of processes and functions:Processes: Access Management, Event Management, Incident Management, Problem Management and Request FulfilmentFunctions: Service Desk, Technical Management, IT Operations Management, Application Management.This list includes three new functions critical for executing process activities and managing service components. These are:Technical Management, which is the custodian of expertise related to all service components. Technical Management typically manages the infrastructurefrom Design through to Operation.Applications Management, which plays a similar role for software applications. Of particular importance is how this function interfaces with ApplicationDevelopment teams throughout the Software Management Lifecycle.IT Operations Management, which may be performed by the previous two functions, but is often centralized into a dedicated unit. This function executesroutine activities, and monitors and controls the health of the infrastructure.
  • 35. Continual Service Improvement is not a lifecycle stage, but a wrapper used throughout the whole service lifecycle. It has inputs and outputs forall lifecycle stages. It focuses on the overall health of Service Management within the organisation.Continual Service Improvement is the continual alignment and adjustment of IT Services to meet the changing business needs by identifying andimplementing improvements to IT Services that support Business Processes.The main purpose and objectives for Continual Service Improvement include:the overall health of ITSM as a disciplinethe continual alignment of the portfolio of IT Services with the current and future business needsthe maturity of the enabling IT processes required to support business processes in a continual Service Lifecycle modelreview, analyze and make recommendations on improvements across all lifecycle stagesmanage the improvement activitiesThe scope of CSI is to:introduce the concepts and principles of CSI at a high level, ensuring buy-indefine the value of CSI to the organisationdefine how and what methods and techniques will be usedCSI has a cycle which covers the following steps:understanding and embracing the high-level business visionassessing the current situation and baselining the analysisdetermining the priorities for improvementdetermining the detailed plan for improvementverifying that measurements and metrics are workingensuring that changes are embedded into the organisation
