Competition

Data center management is a growing major topic for a growing list of large companies who both compete and cooperate, including: Dell, Google, HP, IBM, Intel and Yahoo. Hardware/software vendors who are willing to live with coopetition are working on projects such as "The Distributed Management Task Force" (DMTF) 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.

Among the topics currently being explored are: scalability, securing data center networks,

Business-service management

Business-service management (BSM) treats IT as part of the larger enterprise strategy, and helps fill the gap between business and IT. 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. BSM, which is positioned above

Newer developments

Remote data center management 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, spending in other hardware areas such as

Data center asset management

Data center infrastructure management

Data center-infrastructure management (DCIM) is the integration of information technology (IT) and facility management disciplines to centralize monitoring, management and intelligent capacity planning of a data center's critical systems. Achieved through the implementation of specialized software, hardware and sensors, DCIM enables common, real-time monitoring and management platform for all interdependent systems across IT and facility infrastructures. DCIM products can help data center managers identify and eliminate sources of
risk In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environme ...
and improve availability of critical IT systems. They can also be used to identify interdependencies between facility and IT infrastructures to alert the facility manager to gaps in system redundancy, and provide dynamic, holistic benchmarks on power consumption and efficiency to measure the effectiveness of "green IT" initiatives. Important data center metrics include those regarding energy efficiency and use of servers, storage, and staff. In too many cases, disk capacity is vastly underused and servers run at 20% use or less. More effective automation tools can also improve the number of servers or virtual machines that a single admin can handle. DCIM providers are increasingly linking with

Operations

Information technology operations, or IT operations (ITOps), are the set of all processes and services that are both provisioned by an IT staff to their internal or external clients and used by themselves, to run themselves as a business. The term refers to the application of operations management to a business's technology needs. Operations work can include responding to tickets generated for maintenance work or customer issues. Some operations teams rely on

Outsourcing technical support

Many organizations relocated their technical support departments or call centers to countries or regions with lower costs.

was amongst the first companies to outsource their technical support and customer service departments to India in 2001, but then reshored. There has also been a growth in companies specializing in providing technical support to other organizations. These are often referred to as MSPs (Managed Service Providers). For businesses needing to provide technical support, outsourcing allows them to maintain a high availability of service. Such need may result from peaks in call volumes during the day, periods of high activity due to introduction of new products or maintenance service packs, or the requirement to provide customers with a high level of service at a low cost to the business. It allows businesses to use specialized personnel whose technical

Preventive maintenance

Preventive maintenance (or preventative maintenance (PM)) is ongoing scheduled inspection intended to detect and correct incipient failures either before they occur or before they develop into major problems such as downtime.


Managing the capacity of a data center

With the increasing use of "the cloud" and what has been called "the Era of Infinite Capacity", there is still a need for professional Data Center Capacity Planners. There is a need to know what will be needed, and when. Data must continually be collected regarding usage of power/energy, computing power, data storage and networking/telecommunications. Plans must include awareness of cooling and space requirements. Sometimes analysis of this data, and comparison to industry norms, can be outsourced. The balance for the need to focus more on data collection or analysis depends on current use levels: prior to 50%, the focus can stay more on data collection. Beyond 75%, the focus must shift to analysis, in preparation for upgrades, replacements and expansions. The data center is a resource in its own right.


Top data centers and service providers

According to Cloudscene's Leaderboard for Q1 2018, data center operators are ranked "based on both data center density (total operated data centers)", as well as "the number of listed service providers in the facility". Cloud service providers are ranked based on "connectivity (the total number of PoPs) for the region." Chosen from a pool of more than 6,000 providers, the rankings are as follows: ; Q1, 2018 Top Data Center Operators Worldwide ; Q1, 2018 Top Service Providers Worldwide
