Explain key management tasks and techniques for managing data center.
Answers
Answer:
Data center management[1] is the collection of tasks performed by those responsible for managing ongoing operation of a data center[2] This includes Business service management and planning for the future.
Historically, data center management was seen as something performed by employees, with the help of tools collectively called Data Center Infrastructure Management (DCIM) tools.[3] Now an outsourcing option exists: Data Center Management As A Service - DMaaS.[4]
Both for in-house operation and outsourcing, Service-level agreements must be managed to ensure data-availability.[5]
Coopetition Edit
Data center management is a growing major topic for a growing list of large companies who both compete and cooperate, including: Dell,[6] Google,[7] HP,[8] IBM,[7] Intel[8] and Yahoo.[8]
Hardware/software vendors who are willing to live with coopetition[9][10] are working on projects such as "The Distributed Management Task Force" (DMTF)[11] with a goal of learning to "more effectively manage mixed Linux, Windows and cloud environments."
With the DMTF a decade old, the list of companies is growing, and also includes companies much smaller than IBM, Microsoft, et al.[12]
Focus Edit
Among the topics currently being explored are:[13] scalability, securing data center networks, disaster recovery, government restrictions.[14].
Another major area is the cost of downtime regarding customer dissatisfaction & business loss,[15] and also the "astonishing" yet hidden cost and effect regarding personnel & productivity.[16]
Business-service management Edit
Business-service management (BSM) treats IT as part of the larger enterprise strategy,[17] and helps fill the gap between Business & IT.[18]
IBM notes that major problems often happen in the grey areas, particularly due to errors in the interfaces, and focuses on critical failures. Sufficient redundancy should allow failures in non-critical areas to protect the business from being affected.[18] BSM, which is positioned above IT Service Management (ITSM), promotes a customer-centric and business-focused approach to service management, aligning business objectives with IT or ICT from strategy through to operations. Tools that help BSM include a modeling language,[19] and a common dashboard, which together allow data center personnel to see problems before business customers do.[20]
Newer developments Edit
Remote Data Center Management[21] allows offsite experts to watch for situations needing their timely intervention at a lower cost than having such staff be onsite 24/7/365.
While some requirements for on-site hardware have been reduced,[22] spending in other hardware areas such as UPS may have to increase.[23]
Data center asset management Edit
Data center asset management (also referred to as inventory management)[24] is the set of business practices that join financial, contractual and inventory functions to support life cycle management and strategic decision making for the IT environment. Assets include all elements of software and hardware that are found in the business environment.[25]
IT asset management generally uses automation to manage the discovery of assets[26] so inventory can be compared to license entitlements. Full business management of IT assets requires a repository of multiple types of information about the asset, as well as integration with other systems such as supply chain, help desk, procurement and HR systems and ITSM.
