In Part I of this series, we discuss the components that will be included in Novell Open Enterprise Server, and explained how it will help you expand and solidify the deployment of open source tools in your network. In Part II, we explore the ways Open Enterprise Server can help you make sure that workers in your organization remain productive and have access to the information and services they need to do their jobs. And finally, in Part III we look at what it takes to manage, backup, and provide failover for an enterprise network with hundreds, even thousands of servers, when some of them are Linux boxes.

Managing a single server may not be that hard, but what does it take to manage an enterprise network with hundreds, even thousands of servers? Open Enterprise Server addresses many of the questions you may have regarding manageability of an enterprise-level mixed environment.

  • Management of Linux must fit into our existing management structure. Will it fit in?
  • Can the IT staff be productive from the road and home?
  • Will deployment be easy?
  • We have a diverse IT structure, Linux has to play nice with the rest of the system. Can it coexist with our other systems?

Open Enterprise Server provides integrated global management capabilities and provides the following benefits:

  • Unified management of entire network through iManager
  • Manage from anywhere
  • Role-based and delegated administration
  • Manage mixed NetWare/Linux/Window environments
  • Simple and automatic updates

Integrated, Common Management

We have listened to our customers and really made moves over the last couple of releases to make new server versions additive to exisiting networks, and Open Enterprise Server is the best version ever.

This includes synchronization and gateway technologies for integrated coexistence within your environment. Three examples are shown in the above graphic: CIM-, eDir- and RPM-enablement. These enable common health monitoring, iManager-based management, and patch/update management, respectively.

iManager: Web-based management for the Enterprise

iManager enables you to easily manage your mixed environment, whether that be NetWare, Linux or a combination of both.

Your IT staff must remain productive, regardless of where they may be. The easier it is for them to manage your infrastructure, the more time they can spend on strategic initiatives that add revenue to your business or make your organization more efficient. With iManager included in Open Enterprise Server, management of security, including users and groups, administration of multiple directories as well as storage, server, and printer monitoring is all done through a simple browser. iManager enables you to easily manage your mixed environment, whether that be NetWare, Linux or a combination of both. As one customer put it, ?It's the management tool for the future. It works from where you are, not from where you have installed it.?

User and Group Management

With iManager you can easily create new user objects and assign them rights based on previously determined properties associated with a group. This greatly simplifies IT staff workload.

Directory Management

With iManager and directory synchronization capabilities available separately through Nsure Identity Manager 2, you can ensure user identities and databases are synchronized across the enterprise.

Monitoring

iManager allows you to constantly keep tabs on the health of your network including servers and printers. You can customize the view of iManager to meet your specific organization's needs. Use a graphical representation of the servers across your enterprise or simply a list of servers. Either way you can see the status of a server or service and take action.

Role-Based and Delegated Administration

Open Enterprise Server provides role-based administration so you can delegate administrative responsibilities to those that have responsibility over those services without giving them access to other services in the organization.

Managing an entire network can be a daunting task. Open Enterprise Server provides role-based administration so you can delegate administrative responsibilities to those that have responsibility over those services without giving them access to other services in the organization.

Global administrators can manage the network layout and design, global security and password policies and schema changes.

Group or department administrators can manage specific printer, group and server management for that department.

Help desk administrators can create users, set passwords and clear intruder lockout?among other things.

Seamless Upgrades

All your meta data is preserved (file rights, trustee assignments, use quotas, etc. You can perform in place upgrades from NetWare to NetWare or from NetWare to Linux.

Open Enterprise Server makes it easy for you to upgrade your environment. One of the technologies that make these seamless upgrades possible is Novell Storage Services (NSS). There is no need to move your data. All your meta data is preserved (file rights, trustee assignments, use quotas, etc. You can perform in place upgrades from NetWare to NetWare or from NetWare to Linux.

In the clustered environment, services (including NSS volumes) fail over to other servers in the cluster. After upgrading the server, the administrator can use iManager to move those volumes back to the original server with no disruption to users. This means you can perform NetWare to NetWare or NetWare to Linux upgrades with no downtime.

Coexistence?No Rip and Replace

Open Enterprise Server guarantees that these services can coexist side by side in the same tree or environment, enabling hybrid systems.

The fact that you have the option to deploy Open Enterprise Server services on either NetWare or Linux is certainly an important value by itself. But Open Enterprise Server goes beyond that by guaranteeing that these services can coexist side by side in the same tree or environment, enabling hybrid systems. This ability enables agile deployment of Open Enterprise Server services when you need them on the platform that makes sense to you.

Open Enterprise Server can help companies more easily manage their IT environment and provides the following management benefits:

  • Global, browser-based management
  • Role-based management
  • Easy and automatic updates
  • Management of users, servers and enterprise
  • Integrated management of key open source technologies (Apache-farm management)

Reliability

Open Enterprise Server lets you ensure your services are always available 24/7/365 through high-availability and geo-clustering capabilities.

So you can deploy applications on Open Enterprise Server, provide a productive user environment, improve security and management -- but what about reliability? None of these benefits is worth much if you can't get to the services you need. Questions you may be asking yourself about reliability might be?

  • Do we have assurance that our services will always be available on a Linux platform?
  • Are we sure we will be able to backup all important information?
  • We need to be ready for any disasters. How will Linux help us prepare?

Open Enterprise Server is for the enterprise customer who must ensure that the business critical applications and services that drive the business are available at all times.

Open Enterprise Server lets you ensure your services are always available 24/7/365 through high-availability and geo-clustering capabilities.

File restore and snapshot capabilities in a clustered environment means you have the most current information available at all times and can be prepared for unavoidable risks. For many organizations high-availability is not simply a luxury or a competitive advantage, it is a mandate enforced through government regulation.

Cluster SAN Architecture

With the Cluster Services SAN architecture in Novell Open Enterprise Server you can ensure that your business critical systems are always available.

For many businesses, 24/7/365 access to resources is critical to maintain the organization's viability. The airline, medical, telecommunication and various other industries rely on systems that must be up and running all the time -- no exceptions. With the Cluster Services SAN architecture in Novell Open Enterprise Server you can ensure that your business critical systems are always available. Should one server fail (mother board failure, connection problems, etc.) another server or many other servers are waiting to immediately take over so users have seamless access to what they need. Your server clusters can be NetWare servers, Linux servers or a combination of both. A NetWare server can fail over to a Linux server and a Linux server can fail over to a NetWare server, and end users are never without access to their services. With Novell Open Enterprise Server you can create a two-server cluster out of the box with capabilities to grow the cluster up to 32 servers.

  • Read-only shared volumes
    Improves ease of management for services which require common data access, such as Web server farms.
  • Web Service-enabled failover
    Supports failover of the Novell exteNd Application Server, MySQL, Apache, and PHP/Perl-based services to offer a high availability, 24/7/365 service.
  • Quarantine of failing service.
    Prevents a rogue service from disturbing other services running in the cluster.
  • Maintenance mode.
    Allows administrators to perform maintenance on the LAN and SAN infrastructures without causing inadvertent cluster failovers.
  • XML management.
    All management and statistics are available through XML, which allows for easy scripting and mapping into any management system.

Network Attached Storage (NAS)

Network Attached Storage (NAS) solutions within Open Enterprise Server include full support for simultaneous use of more NAS protocols than any other platform.

Network Attached Storage (NAS) solutions within Open Enterprise Server include full support for simultaneous use of more NAS protocols than any other platform. This includes integration between and with Windows Native networking protocols (CIFS), UNIX/Linux native networking (NFS), Novell Core Protocol (NCP), Apple Macintosh networking protocols (AFP), Web File Transfer Protocols (FTP), Web Hyper Text Transfer Protocols (HTTP) and Web Document Authoring and Versioning (WebDAV).

Management and access control are all enabled through Novell eDirectory, which allows enterprise-wide management as opposed to trying to manage islands of NAS devices in an enterprise. Authorization (login) for Novell NAS solutions is all provided by an enterprise directory service (eDirectory).

Storage Management and Backup

Snapshot allows you to find files for users without restoring from a tape and allows you to backup 24 hours a day because you are backing up from the snapshot.

Wouldn't it be nice to do backups whenever you wanted, not just on the weekend at 1:00 in the morning? Backups can now be done any day of the week, at anytime. And they'll work, too. (Research has shown up to 60 percent of all backups fail.) Snapshot backup removes these barriers. Snapshot tools are integrated into Open Enterprise Server's management console and are independent of hardware vendors. You can even use a mix of storage hardware vendors in your storage infrastructure. Snapshot allows you to find files for users without restoring from a tape and allows you to backup 24 hours a day because you are backing up from the snapshot.

  • Pool Level Snapshot capability (done in the media manager)
    • Up to 1000 active snaps.
    • Mount snap as its own pool.
  • Includes Freeze/Thaw interface for applications so they can ensure data consistency.
    • Freeze/Thaw exposed for third-party snapshot products also.

ISCSI?SANs for the Masses

One of the largest drawbacks has been the cost of buying and deploying a SAN. Open Enterprise Server includes ISCSI support so you can set up a SAN using standard Ethernet equipment.

SANs are a great solution that many companies have evaluated and deployed. However, one of the largest drawbacks has been the cost of buying and deploying a SAN. Problem solved. Open Enterprise Server includes ISCSI support so you can set up a SAN using standard Ethernet equipment. You won't have to incur the high cost of fiber channel, instead you can start today. Everyone can have a SAN.

The networking services and applications you deliver are worthless if they are not available when needed. Open Enterprise Server helps make your network more reliable.

  • Your services are available 24/7/365 so employees, customers and partners get what they need, when they need it.
  • You are providing added levels of protection for your valuable enterprise assets.
  • You can rest assured and relax, knowing you are prepared for any risk and are conforming to government regulations.
