  1. Automate Network Management

  2. managing Multiple Servers • Whatever your Network Operating System, the day-to-day challenges of managing servers are many: • How do I ensure our latest corporate applications and data are accessible throughout the enterprise? • I need to update server applications and deploy service packs • When a server has a problem, I need to know! • How can I better predict when a server will need attention? • I’d like to automate regular maintenance procedures on our email servers • What server hardware assets do we really have? • Is anyone keeping track of what software has been installed on each server? • How do I handle my servers’ various needs when some are not at my same site? NetWare Linux Solaris Windows

  3. network serversimpact the entire workforce • Is email back online today? • IT has not rolled out the latest virus package to our site yet… • Can my lost data be recovered? • Headquarters has the latest office templates. Why don’t we? • I could research this report if only I could access the Internet. • Which servers are down this time?

  4. introducing…Novell ZENworks for Servers 3 the cross-platform solution for server content and configuration management

  5. ZENworks for Servers Automates Server Policies Server Content Distribution Server and Infrastructure Management The Golden Triangle of ZENworks for Servers

  6. Server Infrastructure Management • Monitoring and Management

  7. What Are the Two Methods of Server and Infrastructure Management? • Reactive management • Wait to fix a problem until the phone system goes downdue to an overload of calls to the help-desk • Proactive management • Find the problem and fix it before anyone else knows about it

  8. Monitoring and Management • Network tools for the enterprise infrastructure management • Monitors • NetWare and Windows servers • Critical resource alerts (disk space, memory, utilization, etc.) • Network capacity planning • Segment and switch traffic • Manages • Network mapping (dynamic discovery) • Server inventory data • Network reporting • SNMP devices (routers and other devices)

  9. ZfS 3 Management Architecture Sybase CIM compliant database eDirectory™ ConsoleOne SNMP, NCP, Diagnostics, Inventory LANalyzer Managed workstation Managed server Managed router/switch

  10. Atlas Paradigm

  11. NetWare Management Agent • Deploy on each managed server • Open standard SNMP interface • NetWare server MIB • System, File System • Connections, User Accounts • Queues, ODI, SFT-III, NCP, Watchdog • NLMs, Set Parameters • NetWare server & NDS trap MIBs • 400+ NetWare alarms and events. • 128+ NDS alarms and events

  12. Node Summary

  13. Server Memory View

  14. Trend View

  15. Alarm Handling

  16. Software\Hardware Inventory

  17. Trend View - Network

  18. Remember... • It only takes one small change to go from Networking to Notworking!

  19. Server Policies • Policy Based Management

  20. What are Server Policies? • Server Policies: • Enforce configurations • Schedule server procedures • Provide consistency andstandardization • Put servers into groups to simplify configuration changes to multiple servers.

  21. Configuration Text File Changes NetWare-Set Parameters SNMP Configuration Behavioral Server Down Process Scheduled Down Server Scripts Scheduled Load & Unload Types of Server Policies • Email Server Policy: • Unload messaging services before down • Tune for optimal email performance Server Server Sever group

  22. Web Based Management • Enables the server administrator to view/enforce policies one at a time or all at once via any workstation with a browser.

  23. Server Content Distribution • Tiered Electronic Distribution

  24. Tiered Electronic Distribution (TED)automatically distributes data to multiple servers in the most WAN-efficient manner possible What is TED?

  25. TED is comprised of four logical components Distributors package and send distributions to subscribers through logical channels Distributions can be Files and folders Server software packages Data from FTP & HTTP sources ZENworks for Desktops 3 application RedHat RPM’s Policy Packages Channels logically group distributions Subscribers receive distributions from distributors through channels What is TED?

  26. Compression over wire Distributions are compressed before being sent Scheduling WAN use and other actions are all based on schedule Bandwidth Throttling I/O can be carefully controlled Checkpoint Restart Interrupted distributions can resume Distribution Hierarchies (Tiered Subscribers) Discussed on next slide TED: WAN Optimization

  27. Simple Example An NT subscribercould receive service pack distributions for Microsoft BackOffice by subscribing to a “BackOffice” channel This and another subscribermight both use an “Anti-Virus” channel to receive data specifically for Anti-Virus Updates Again, the distributor is the crucial component that gathers, packages, and sends the distributions TED Distribution Hierarchies Distributor BackOffice update distribution Anti-virus Update distribution “BackOffice” channel “Anti-Virus” channel BackOffice Server (subscriber) File Server (subscriber)

  28. Parent Subscribers Reduce bandwidth utilization across WAN links Re-distribute as they receive distributions, so next-level subscribers receive at virtually the same time as their parent subscriber Can be dynamically configured from any subscriber because both run from the same code TED: Parent Subscribers Distributor Parentsubscriberat a remote site Local subscriber Remote site subscriber Remote site subscriber Remote site subscriber

  29. Platform Support TED and Policies (Distributors, Subscribers and Policies) • NetWare 5.1 and 6 • NT4 & W2K (Servers) • Linux – Red Hat 7.1 • Solaris 8 Inventory and Remote control on NetWare/NT/W2K platforms only TED and Policies will now be referred to as PDS (Policy and Distribution Services)

  30. Apps OU is Created, if needed Application Acrobat4 Created Group OU and Group AppUsers Created, if needed Associations Made, if applicable Application Distribution Agent – Acrobat4 Example Novell Chicago Provo Associations Exist Apps Apps Acrobat4 App Obj Acrobat4 App Obj Groups Groups AppUsers AppUsers

  31. Web Based Management • ZENworks for Server 3 adds Web management via Novell iManager to manage: • Distributors • Subscribers • Distributions • Policies • Requires IE 5.5 or above (does not fully support NetScape or other browsers)

  32. Web Based Management • Tiered Distribution View enables you to track a Distribution throughout the entire TED system from the Distributor's point of view.

  33. Web Based Management • Shows configuration data for Distributor, Subscriber and info shared across both TED pieces

  34. 27 Related BrainShare Sessions! • See ZENworks for Servers sessions: • TUT211 - Deploying ZENworks Inventory • TUT212 - Novell ZENworks for Servers 3: Distributing Novell Application Launcher Applications through Tiered Electronic Distribution • TUT215 - Network Management and Monitoring Using the Components of ZENworks for Servers • TUT216 - Implementing ZENworks for Servers Policies and Distribution Services • TUT309 - Deploying NetWare Support Packs Automatically with ZENworks for Servers

  35. ZENworks and PacifiCorp • “During a recent virus scare, we realized that the version of our anti-virus software would not completely cure the virus, even with new definitions. Within the course of one day we pushed out a new version of anti-virus software with the latest virus updates to 6,000 desktops across our 105 different locations. This saved around 1,000 man-hours, if not more. Where viruses are concerned, the speed and reliability offered by ZENworks are extremely important.” • Clint Lundmark, Network Engineer,PacifiCorp

  36. how much savings can you achieve? “The average savingsover a three-year period from deploying ZENworks havea net present value of$44,965 per 100 users.” Quantifying the Business Benefits of Directory Based Desktop Management May 2001
