<strong>Data</strong> <strong>Center</strong> <strong>LAN</strong> <strong>Migration</strong> <strong>Guide</strong><br />
Significant levels of integration can be done in fault, performance, and network configuration and change<br />
management. As an example, IBM’s Tivoli NetCool is a well established leading multivendor solution for fault<br />
management. <strong>Juniper</strong>’s Junos Space platform licenses and integrates NetCool into its Junos Space offering. There<br />
are also well established multivendor solutions for performance management that include IBM NetCool Proviso,<br />
CA eHealth, InfoVista, and HP OpenView that an enterprise can consider for managing network and application<br />
performance for both current vendor and <strong>Juniper</strong> network infrastructures.<br />
There are currently over a dozen Network Configuration and Change Management (NCCM) vendors with multivendor<br />
tools. These tools bring more structure to the change management process and also enable automated configuration<br />
management. NCCM vendors include IBM Tivoli, AlterPoint, BMC (Emprisa<strong>Networks</strong>), EMC (Voyence), HP (Opsware),<br />
and others. Prior to introducing <strong>Juniper</strong> into an existing single vendor infrastructure, <strong>Juniper</strong> recommends that you<br />
replace manual network configuration management processes and vendor-specific tools with automated multivendor<br />
NCCM tools. It is also good practice to establish standard network device configuration policies which would apply to<br />
all vendors in the network infrastructure. Automated network configuration management is more efficient and also<br />
reduces operational complexity. An IT management solution should be built around the standards outlined by the<br />
Fault, Configuration, Accounting, Performance, Security (FCAPS) Model.<br />

Integrating Management and Orchestration with Junos Space<br />
Some amount of integration for management and orchestration can be accomplished using Junos Space. Junos Space<br />
is a network application platform for developing and deploying applications that simplify data center operations. Junos<br />
Space abstracts network intelligence such as traffic flows, routing topology, security events, and user statistics (to<br />
name a few), and makes this available as services used both by <strong>Juniper</strong>-developed applications and applications from<br />
third-party vendors leveraging the Junos Space SDKs/APIs. Junos Space applications are designed to be collaborative.<br />
They share common services such as inventory and configuration management, job scheduling, HA/clustering, etc.,<br />
and they use a common security framework. This enables users to optimize scale, security, and resources across their<br />
application environment. The Junos Space application portfolio currently includes Ethernet Design (rapid endpoint and<br />
switch port configuration in campus/data center environments), Security Design (fast, accurate deployment of security<br />
devices and services), Network Activate (point/click setup and management of VPLS services), Route Insight (visibility,<br />
troubleshooting, and change modeling for L3 MPLS/IP networks), Virtual Control, which provides a consolidated<br />
solution for network administrators to gain end-to-end visibility into, and control over, both virtual and physical<br />
networks from a single management screen, and Service Now (automated case and incident management).<br />
<strong>Data</strong> <strong>Center</strong> Consolidation Trigger Event<br />
Numerous large enterprises are consolidating their geographically distributed data centers into mega data<br />
centers to take advantage of cost benefits, economies of scale, and increased reliability, and to fully exploit the<br />
latest virtualization technologies. According to industry research, more than 50% of the companies surveyed had<br />
consolidated data centers within the last year and even more planned to consolidate in the upcoming year. <strong>Data</strong> center<br />
consolidation can involve multiple insertion points into access and core aggregation layers as well as consolidation of<br />
security services.<br />
Best Practices in Designing for the Access Layer Insertion Point<br />
We have already discussed the recommended best practices for the access layer insertion point. In this section, we will<br />
highlight key best practice/design considerations for the other insertion points related to the consolidation trigger event.<br />
