- 2. Device42, Inc. | Copyright 2015 2 INTRODUCTION Managing physical, logical, and cloud infrastructures in a data center involves an expansive range of capabilities. While there may be numerous ways to define these capabilities, here is one perspective that outlines the key areas for data center infrastructure management (DCIM) solutions: ▪ IP Address management ▪ Inventory/asset management ▪ Power and environmental monitoring and control ▪ Impact management ▪ Password management ▪ Cloud management ▪ Cable management Regardless of how these areas are classified, effectively managing a data center comes down to having a centralized data center infrastructure management (DCIM) tool that makes IT assets visible, understandable, and controllable. This white paper will explore both the challenges and critical considerations of effectively managing data center assets along with solution capabilities that make effectively man- aging IT assets possible. IDENTIFYING THE COMMON CHALLENGES One of the best ways to illustrate the many challenges and areas of expertise involved in managing en enterprise data center, is to address common scenarios experienced by CFO’s, CIO’s, CTO’s, and IT managers: It’s budget time one again and you have numerous requests for new servers. The projects all sound worthwhile. But you barely received CAPEX approval for last year’s servers and face a similar task again. To prepare for budget discussions you need a host of questions answered: ▪ How are the servers purchased last year being used? ▪ What applications are running on which servers? ▪ Which business units, cost centers, projects, or departments are assets assigned to? ▪ How much is each business unit, cost center, project, and/or department costing in IT assets? This white paper will explore both the challenges and critical considerations of effectively managing data center assets ...

While the team begins addressing the problem, affected cus- tomers and internal users need to ne notified. But the team doesn’t know the applications running on the affected servers, much less who the users are. ▪ Your servers are in a colocation facility and you periodically exceed your planned energy expense. You’d like to consider solutions to remain within your power allotment without affecting critical application services. The problem is you don’t have any way to look at historical energy usage and you don’t know which servers are running critical vs. low priority applications. ▪ It’s audit time again and the auditors want to know what users have write access to each server, database, and application. They also want you to prove that pass- words have been changed every 3 months over the past year. How do you do that? ▪ You need to create disaster recovery and business continuity plans but no one knows which applications and users will be affected by losing which servers, switches, and other devices. Unfortunately, these situations, and numerous other ones like them, are common experi- ences for data center managers and engineers. Fortunately, they issues do not have to be problematic or challenging. Addressing these issues starts with understanding and managing the interdependencies between IT assets. THE INTERDEPENDENCIES OF IT ASSETS The assets within your data center are numerous and diverse spanning multiple categories across physical, logical and cloud environments: ▪ Switches, routers ▪ Buildings, rooms, racks ▪ PDU’s ▪ Spare parts (CPU’s, disk drives, RAM, etc.) ▪ Software applications, operating systems, database platforms ▪ Storage networks ▪ Physical, virtual, and cloud servers ▪ IP space, subnets, VLANs, VRF groups, MAC addresses ▪ DNS ... assets within your data center are numerous and diverse spanningmultiple categories ...

Device42, Inc. | Copyright 2015 4 ▪ Patch panels ▪ Users and user groups ▪ Accounts and passwords ▪ Software services running on devices ▪ Applications running on devices ▪ Miscellaneous assets including: HVAC, breaker panels, DMARC’s, fabric extenders, fax machines, filler panels, monitors, projectors, scanners, shredders, sensors, … and more And all of these assets have many interdependencies with one another. For example, ▪ IP addresses are assigned to devices ▪ Applications can be on physical, virtual, or cloud devices ▪ Customers and internal users are dependent on applications ▪ Passwords are assigned to devices and applications ▪ Users and groups need varied access privileges ▪ Assets are interconnected by switches and patch panels ▪ Assets are connected to and powered by PDU’s The point is, assets and their interdependencies are extremely complex and having an accurate visibility and an understanding of these assets and their independencies is critical to effectively managing the data center. Furthermore, the need to understand these interdependencies is no more apparent than during scheduled and unscheduled data center outages. That’s where data center infrastructure management software (DCIM) serves as a power tool. EXPLORING THE VIRTUES OF DATA CENTER SOFTWARE Remembering the scenarios addressed earlier in this document, it is safe to say that a single, comprehensive DCIM software solution can prevent the common frustrations experienced by data center managers and engineers. More importantly, the right DCIM software can provide accurate, real-time information that enables proactive data center management, improved responses to unplanned service outages, better user support, and increased responsiveness to organizational needs – to name a few.

Device42, Inc. | Copyright 2015 5 DCIM SOLUTION COMPONENTS While the capabilities of DCIM software vary by solution provider, and some vendors may provide limited but “deep” solution capabilities in a limited few number of data center disciplines, the scope of DCIM solution can span multiple disciplines and operational areas as depicted the “DCIM Solution Components” diagram shown below. Put simply, data center infrastructure management software enables companies to track and manage IT assets, their interactions, and their dependencies. From a finance perspective, DCIM software also enables companies to track the costs of all these assets by department, cost center, project, customer, and user. DCIM software is also a vital tool in effective capacity planning (e.g. adding locations, rooms, colocation cages and/or racks). For example, with accurate information about IT assets, including their capacities and their utilization, companies can avoid unnecessary cost by using existing racks or other hardware rather than buying new. This capacity per- spective is not only invaluable in the routine management of data center hardware costs, but also in the management of unplanned capacity changes where urgent time constraints are components in a timely resolution. Using DCIM software, companies can also construct realistic budgets based on actual expenditures by department or cost center. In addition, DCIM software can accurately provide information that enables accurate IT cost allocations by business unit. With the shift toward virtualization and cloud services, DCIM software can also help organi- zations analyze virtualization usage and provide data that can be vital in architecting or deconstructing data centers with physical, virtual and cloud components. DCIM software can also be a vital tool to accurately understand the impact of both panned and unplanned system outages and performance issues. With the right DCIM software, the relationships between devices, software, and users is clearly defined, visualized, and instantly available. ... data center infrastructure management software enables companies to track and manage IT assets, their interactions, and their dependencies. SOLUTION COMPONENTS

Device42, Inc. | Copyright 2015 6 From within a single DCIM console data center staff can monitor, report, analyze and even control power utilization at intelligent PDUs and outlets that service, racks, rooms, servers, and even buildings. DCIM software capabilities should also include the ability to monitor environmental sensors such as temperature, humidity, presence of water, access and egress sensors, and more. While these capabilities represent only a portion of the capabilities of a comprehensive DCIM solution, they provide insight into how DCIM software can address the common issues involved in managing a data center. DCIM SOFTWARE WRAP-UP By now, it is clear that DCIM software has the potential to dramatically impact data center manageability as well as service and support of your IT infrastructure. Be aware that the DCIM marketplace has been established for more than a decade and that there are a range of solutions that support specific aspects of managing a data center. The result is that managing a data center with comprehensive functionality could result in using multiple relatively high-priced, narrowly focused solutions – each with a unique UI and management console.

If your organization is considering the introduction of a DCIM tool into your data center, or considering deploying an additional DCIM tool to address specific data center needs, be sure to define and prioritize your requirements before engaging with DCIM solution providers. This will enable your enterprise to match the best solution to meet your needs, instead of aligning your business to meet the capabilities of DCIM solutions available on the market today. Lastly, ensure your evaluation of the solutions includes a complete understanding of the implementation requirements, the challenges or ease of integrating the solution to your data center, the accuracy of the provider’s capability claims, the support requirements for operating the solution within the enterprise, and, most important of all, the references and experiences of clients that have deployed the solution in organizations and environments similar to yours. Data Center Infrastructure management solutions can have a profound and positive impact of your data center operations. The effectiveness of “homegrown” solutions based on desktop technologies such as Excel and Visio is usually a fraction of the effec- tiveness of purpose-built data center management solutions. As a result, exploring DCIM solutions is an exercise that can yield significant benefits and advantages. Data Center Infrastructure management solutions can have a profound and positive impact of your data center operations.
