Data Center Manager (DCM)
Unified Virtual/Physical Data Center Fabric Management
Virtualization technologies are increasingly being deployed in the data center because of their ability to drive the efficiency and effectiveness of computing and storage resources. However, the dynamic nature of virtualization along with the traditional organizational separation between server and network management teams can lead to management challenges.
In order to create an agile and automated operational model for the virtualized data center, IT administrators require a more comprehensive set of automation capabilities, coupled with increased network visibility and more granular controls. Extreme Networks Data Center Manager (DCM) addresses these new operational requirements and provides functions that ensure consistent application performance and unified management across the physical and virtual network.
DCM provides IT administrators a transparent, cross-functional service provisioning process that bridges the divide among the server, networking and storage teams, ensuring each has an integrated view of virtual server and network environments. With a unique vendor agnostic approach, DCM supports a variety of virtualization, storage and server platforms, enabling the unification of the physical and virtual network and ensuring networks will have the high availability necessary for critical applications and business data.
In addition to server, storage and network virtualization, the VDI (Virtual Desktop Infrastructures) add-on enables standard desktops to be virtual machines. Users can access their virtual desktop from various devices like their physical desktops, laptops, thin clients, mobile devices, tablets, or smartphones. This provides a secure mechanism to support mobile devices and BYOD (Bring Your Own Device) initiatives. There are many advantages to using VDI including improved service to the user and reduced operational cost for the support organization. Enterprise security is strengthened since the data is kept within the data center and is not stored on the device itself. Support costs decrease because patch management and recovery are centralized and the device accessing the desktop can easily be replaced with no configuration required. VDI also turns the access control model upside down – from client side enforcement to server/VM side enforcement. It is key to keep the same controls in place in the data center as in a typical fat client environment. The VDI Integration based on DCM enables user based policy management in the VDI data center to address this requirement.
- Automated unified provisioning improves efficiency in the virtualized data center
- User based policy management for VDI improves security and efficiency in a VDI data center deployment
- Comprehensive virtual machine and VDI visibility optimizes resource use and decreases troubleshooting time
- Integrated workflow process reduces IT workload and helps control VM sprawl
- Vendor agnostic technology supports a variety of virtualization platforms
- Simplified compliance addresses data center requirements through policy enforcement and traffic monitoring per VM
Traditionally, data center connectivity spans physical, virtual and storage networks using separate tools and management systems. To unify a data center network, it is necessary to have an integrated view of the network infrastructure, servers, storage systems and applications. The Extreme Networks Data Center Manager solution is designed to reduce the workload and increase the efficiency of the IT organization. Coordinating the automated assignment of virtual machines (VMs) within both the virtual and physical network fabrics, DCM ensures that proper network resources are allocated when a VM is provisioned, no matter where it is on the network. This is achieved with DCM's unique ability to automatically apply individual policies to various data objects in the switching fabric, solving the challenge of virtual machine sprawl. The use of granular policies, combined with Extreme Networks flow-based switching, helps users realize the goals of high availability and reliable delivery. With this approach, operational costs are lowered by providing a higher degree of automation as well as system-level management.
An important part of managing today's virtualized environment is the automatic application of individual and unique policies to various data objects in the switching fabric, including mobile VM sessions, users, applications and storage traffic. Extreme Networks Data Center Manager establishes network profiles for physical and virtual machines and distributes them within the network fabric, as well as coordinates the profile assignment of virtual machines to ensure consistent delivery of services regardless of the physical location of the VM.
DCM ensures that when network configurations are made, communication between the network and virtual switch (vSwitch) is greatly improved and configuration mismatches are eliminated. Each group within the IT organization has insight across the entire data center – servers, storage and networks. When the networking team makes a change, such as setting the quality of service (QoS) for an application, that change is automatically propagated across the corresponding VM. This cuts down on the manual steps needed when, for example, the server team puts in a request to the networking team for provisioning a new server. Instead, the change can be automatically applied to the network.
The organizational benefits of DCM include:
- Streamlining virtual network configuration to reduce the chance of errors as well as enable faster troubleshooting
- Eliminating the need to constantly communicate network or virtual network changes between teams
- Ensuring consistent network policy across all data center clusters
Visibility, Tracking and Monitoring
Tracking and monitoring the virtual machine inventory of a typical data center can be challenging and time consuming. IT administrators often find it difficult to know how many VMs are on the network, when they were deployed and by whom. Discovering which resources were allocated to the VMs and what operating system images they are running becomes even more problematic. To make the provisioning and management of VMs efficient, inventory information must be integrated with network management.
Extreme Networks Data Center Manager provides real-time VM asset monitoring and historical location tracking within NetSight™, Extreme Networks management solution. NetSight delivers the centralized visibility, granular control and automation required for the efficient management of this capability. NetSight is distinctive for granularity that goes beyond ports and VLANs down to individual users, applications and protocols. Built upon open standards, it can integrate with third-party enterprise management platforms. NetSight enables staff to avoid timeconsuming manual switch-by-switch configuration tasks.
DCM brings the integrated tracking of a virtual machine and its applications to NetSight. The synchronization of asset information into NetSight through DCM allows the network team to have full visibility into VM-specific asset data for all the major hypervisors, including vSphere and/or XENCenter and/or Microsoft Hyper-V via Windows Server 2008.
Operationally, NetSight with DCM lowers costs by automating virtual network modifications and improving management control with granular visibility of network traffic and virtual machine data.
Integrated Workflow Process
Extreme Networks Data Center Manager integrates with existing workflow and lifecycle tools to provide cradle-to-grave visibility into virtualized and physical assets, and to automate the physical and virtual network configurations for virtual machines. DCM requires no software installation on the hypervisors. Instead, it leverages each vendor's APIs and Extreme Networks published APIs to provide automated inventory discovery and control of the hypervisor switch (VMware, Citrix XEN, Microsoft Hyper-V) configuration as well as management of the physical network configuration.
DCM is designed to reduce disruption to the IT workflow and increase the efficiency of the organization. IT administrative efforts can be decreased with the automation of routine tasks and integration of existing management systems. User-based and application-based policies save time and avoid costly errors when compared to traditional port-based and VLAN-based access control list (ACL) methods for network security and application provisioning. The end result is an automated data center which ensures resiliency, performance and data integrity.
Extreme Networks Data Center Manager interfaces directly with the native operating system. Server and VM visibility and control are provided without bias to the server or operating system vendor. IT administrators have the freedom to choose the server vendor that best fits their requirements. DCM integrates with popular server virtualization products from Citrix, Microsoft and VMware. This capability is unique to Extreme Networks, providing the IT organization with unparalleled flexibility to choose from any of the leading server virtualization vendors.
Given the security and compliance mandates for data center design, the Extreme Networks network infrastructure provides built-in security functionality for auditing data center networks. This functionality assists in tracking compliance with PCI, Sarbanes Oxley, ISO 17799 and other key industry regulations without the need for add-on appliances.
Extreme Networks Data Center Manager allows administrators to determine who has access to network resources, which devices can access the network and when, as well as the compliance level of each end system attempting to access the network.
DCM enables control of VM-to-VM communication and leverages hardware-based unsampled NetFlow, provided by the Extreme Networks S-Series, for application and behavior monitoring. By automating provisioning processes, increasing network visibility and flagging control deficiencies, DCM helps to simplify compliance and the costs associated with it.
