Oracle Enterprise Manager Ops Center: Managing Datacenter Complexity

Oracle Enterprise Manager Ops Center — Managing Datacenter Complexity

Executive Summary

Today datacenter managers struggle with a fragmented infrastructure consisting of a wide

range of proprietary and single-purpose tools. Complicating the issue is the widespread use of

virtualization solutions to increase resource utilization and consolidate hardware resources in the datacenter. The result is a complex, hard-to-manage infrastructure that cannot scale to ® meet growing demand. Oracle Enterprise Manager Ops Center delivers a converged hardware management solution for Sun environments that integrates management across the infrastructure stack. With advanced virtualization management and reporting capabilities, application-to-disk management, intelligent configuration management and more, Oracle Enterprise Manager Ops Center helps IT managers reduce complexity and streamline and simplify infrastructure management.

Introduction IT systems are evolving to address key business requirements, and there is greater dependency and reliance on enterprise computing resources. However, today’s datacenters consume physical space at a rapid rate, overuse power, and are costly, complex, and difficult to manage. As a result, there is an urgent need for increased datacenter performance and efficiency. Toward this end, IT departments are rushing to upgrade to new infrastructure and virtualize systems to affect better resource utilization.

While providing significant improvements, these technologies contribute change and complexity at a time when datacenters are already understaffed and overburdened. Placing just two or three virtual environments on an existing server can double or triple the administrative workload for IT staff if not implemented properly. In addition, introducing virtualization technologies adds greater complexity by blurring existing lines of responsibility.

Virtual deployments can cross traditional groups of dedicated administrative staff, creating doubt about which group is responsible for managing business services and the underlying infrastructure. Datacenter administrators are caught in the middle with tools that fail to keep

pace with technological developments. Forced to cope with a disconnected set of singlepurpose tools, and struggling with scripts and labor-intensive manual processes, IT organizations face a breaking point where they are no longer able to manage various datacenter infrastructure layers or scale effectively to support rapid change and complexity.

Oracle Enterprise Manager Ops Center addresses this challenge with a converged approach that integrates hardware management across the infrastructure stack, helping organizations to streamline operations, increase productivity, and reduce system downtime. Unique and comprehensive application-to-disk management capabilities come together within Oracle Enterprise Manager to further simplify administration, increase efficiency, and break down barriers between management silos.

Oracle Enterprise Manager Ops Center Architecture Oracle Enterprise Manager Ops Center utilizes a unique three-tier architecture that supports rapid scalability and secure management with a centralized enterprise controller and distributed proxy controllers to manage datacenter assets. The combination of an enterprise controller, proxy controllers, and other architectural components provides layer-by-layer, end-to-end management of the complete hardware stack from servers and operating systems to virtualization, storage, and networking. Figure 2 illustrates the Oracle Enterprise Manager Ops Center three-tier architecture.





Figure 2. The three-tier architecture of Oracle Enterprise Manager Ops Center provides end-to-end datacenter asset management.

Oracle Enterprise Manager Ops Center Enterprise Controller A centralized server that consolidates management of systems, the Oracle Enterprise Manager Ops Center Enterprise Controller is the core of Oracle Enterprise Manager Ops Center. Connecting to managed systems through proxy controllers, it generates the browser interface, routes commands from users to the proper proxy controller, and communicates with Oracle Support and other external data sources.

Oracle Enterprise Manager Ops Center can operate in either connected or disconnected mode. By default, Oracle Enterprise Manager Ops Center operates in connected mode, enabling the software to download operating system (OS) patches and other new software automatically using internet access. It is possible to use a combination of connected and disconnected modes to maintain datacenters. For example, the enterprise controller can be switched to connected mode to check for patches, connected

to the internet to get information, disconnected from the internet, and switched back to disconnected mode when finished.

Oracle Enterprise Manager Ops Center Proxy Controller Proxy controllers monitor and manage systems within individual security domains and communicate status back to the enterprise controller. The enterprise controller places actions in a job queue on the proxy controller in chronological order. When a job stops, the next job in the queue is started.

Utilizing multiple proxy controllers creates an architecture that supports massive scalability and enhances performance by distributing the network load and reducing the amount of traffic between the enterprise and proxy controllers. It also contributes to greater security by isolating each security domain managed by a proxy controller.

Oracle Enterprise Manager Ops Center Agent Controllers

Agent controllers are lightweight Java™ software that perform management, OS patching, and compliance monitoring operations for OS assets and virtual OS instances. Hardware management tasks such as firmware provisioning do not require the use of agents. Agent controllers are installed on operating systems and virtualized environments managed by Oracle Enterprise Manager Ops Center and communicate with a specific proxy controller, retrieving commands from designated proxies, performing required actions, and notifying the proxy of the results. The agent controllers can be viewed for information such as status, current version, and any available updates.

Oracle Enterprise Manager Ops Center Knowledge Base

The Knowledge Base contains metadata on consistent, supported configurations for the Oracle Solaris and Linux operating systems. For example, an OS release could be noted in the Knowledge Base as requiring a specific firmware revision and a particular set of patches before being deployed. Knowledge Base data can include patch dependencies, standard patch compatibilities, withdrawn patches, and download and deployment rules. The Knowledge Base also maintains URLs for vendor downloads and retrieves download components from the appropriate vendor download site.

Other Architecture Components Oracle Enterprise Manager Ops Center contains several other components that perform important management functions.

Oracle Enterprise Manager Ops Center Virtual Controller. Oracle Enterprise Manager Ops • Center lets IT staff manage virtual server assets and resources created by Oracle Solaris Containers or Oracle VM Server for SPARC. The Oracle Enterprise Manager Ops Center Virtualization Controller manages and monitors the agent software on a virtual asset as if it were a physical component.

Libraries. The libraries of Oracle Enterprise Manager Ops Center store and manage cached data, • images, patches, and metadata. This can include copies of operating systems, OS patches, firmware

Oracle Enterprise Manager Ops Center — Managing Datacenter Complexity

revisions, virtual appliance images, and golden master images. The libraries are organized into the following categories.

The OS Provisioning Library. The OS provisioning library manages the OS images and profiles.

• Maintained in ISO format, the images can be used to provision one or more systems with an OS.

• The Updates Library. The updates library is used to manage updates or patches for the Oracle • Solaris and Linux operating systems, as well as Microsoft Windows.

NOTE: Oracle Enterprise Manager Ops Center uses Microsoft System Center Configuration Manager (SCCM) for updating the Windows operating system. The Windows Update functionality depends on the SCCM agent installed on the managed systems. SCCM can be configured to install agents on managed Windows systems either automatically or through a manual process.

Storage Libraries. When a guest or virtual image is created, the configuration information for its • operating system, data, CPU, memory, and network details are saved as metadata in a storage library. Oracle Enterprise Manager Ops Center supports two types of storage libraries—Fibre Channel and Network Attached Storage (NAS), depending on the virtualization type. Once controlled by Oracle Enterprise Manager Ops Center, storage libraries can provide disk resources to virtual machines. Should migration of the storage from one virtual machine to another become necessary, Oracle Enterprise Manager Ops Center can orchestrate moving the underlying storage in a process that is transparent to operators. For more information on storage virtualization support in Oracle Enterprise Manager Ops Center, see the Utilize Resources More Efficiently section in this paper.

Key Capabilities and Features Oracle Enterprise Manager Ops Center delivers a converged hardware management with powerful

features that dramatically improve IT efficiency. With these features IT staff can:

Extend asset management to storage and network resources • Streamline operations and speed deployments •
