Award-winning NetWare—rock-solid, reliable, economic network services
IT managers and network administrators know and trust NetWare based on years of reliable service from their existing Novell
installations. NetWare 6.5 builds upon two decades of constant performance and reliability improvements.
Many companies, perhaps frightened by the scare tactics used by some software companies, want to dip cautiously into the open
source pool. As a firm foundation, NetWare 6.5 supports open source applications and development tools while relying on a set of
networking services. In a word, the issue is choice—you and your organization determine the appropriate mix of technologies, and
Novell provides you with the best platform and framework to reliably run your enterprise.
Business continuity
Network downtime causes you real pain, not to mention the thousands or even millions of dollars your business loses for every hour
down. Every network administrator needs a plan to fall back on when that happens. Business must go on as usual. The high-level
business continuity solutions included in NetWare 6.5 dispel that potential pain.
NetWare 6.5 includes updated administration tools, new server consolidation services, improved branch office support, advanced
clustering for high-availability of network resources, major improvements in storage management and stronger directory services.
Improved administrative tools, including increased remote support
Network management needs evolve, and the push for greater administration flexibility means that tools must evolve too. NetWare 6.5
continues that evolution with an improved browser-based management utility, iManager.
Moving toward the complete management portal, iManager now supports the following:
- Storage resources
- Server diagnostics
- Printers
- Intrusion detection
- Outages
- Branch office connections
This new unified remote management utility supports a variety of browser platforms all the way down to popular PDA models. Remote
management becomes a reality rather than an item on your wish list. (See Figure 3) Functions from Web Access, ConsoleOne,
NetWare Administrator and even some Cworthy interface tools are migrating to iManager.
Server Consolidation Utility 2.0
Things change, and those things often include network components. Customers upgrade their server hardware, operating systems and
data on a regular basis. Making those moves easily, painlessly and safely falls into the hands of the NetWare 6.5 Server
Consolidation Utility version 2.0.
Developed from more than two years of customer research, including surveys from more than 4,000 NetWare administrators, the
biggest advantage of the new Server Consolidation Utility 2.0 can be summed up in one word: nondestructive. Migrations can be
implemented, checked, revised and redone with absolute confidence that your data remains safe and secure.
Both resource migration and resource consolidation fall under the Server Consolidation Utility 2.0 banner. Even though they are
technically two different processes, migration and consolidation share many functional techniques to achieve their goals. Many
projects combine a mixture of resource reallocation, migration and consolidation, making this utility a primary tool for
administrators.
Server Consolidation Utility 2.0 is like "ncopy on steroids." files are copied from server to server, not from server to client to
server.
eDirectory information copied includes:
- stream data
- attributes
- inheritance filters
- ownership
- trustees
- size restrictions
Anything you can back up from a server, the server consolidation utility 2.0 can copy.
Origination servers include:
- NetWare 4.10
- NetWare 4.11 (SP9) / NetWare 4.2
- NetWare 5.0 / NetWare 5.1
- NetWare 6.0
- Windows NT
- Novell Nterprise Branch Office appliance
Destination servers include:
- NetWare 5.1 / NetWare 6.0
- NetWare 6.5
Reasons for server consolidation vary from network to network, but common themes emerge. Changing a network requires moving and
combining files, data and other network resources. Every inherited network becomes a candidate for consolidation, whether the IT
manager moves into an existing network, or merges a new network into a once-orderly and well-planned installation.
As networks change in response to different organizational needs, particularly in the new world of Web services, IT managers
find themselves with more hardware and software configurations than they can comfortably manage. When a new tool appears, such as
the Server Consolidation Utility 2.0, smart managers take advantage of them.
Storage services generate network changes as administrators struggle to keep up with exploding storage needs. Storage Area Network
(SAN) options, once too pricey for all but the largest companies, have dropped into the affordable range, especially when controlled
by NetWare. The flip side of more storage? As you acquire more storage, you also need to rearrange it, which means you’ll soon be
consolidating again.
Experienced NetWare administrators remember NCOPY, a command line utility able to duplicate files within the storage confines of
one server while retaining NetWare file attributes lost when using DOS or Windows file utilities. NCOPY bypassed the client in the
copy process, using an internal directory-to-directory copy method within the server.
Originating file systems include traditional volumes and Novell Storage Services (NSS). File destinations include traditional, NSS
and cluster volumes.
You can consolidate printing resources, as well as move Novell Distributed Printing Services (NDPS) and any Printer Server Manager
(PSM). Using the graphical interface, drag a printer agent and drop it on a new printer manager. When dropped, all the printer agent
information moves rather than just being copied. You can also move multiple printers at one time. Any outstanding print jobs remain
stranded, as you might expect.
On the hardware side, NetWare 6.5 includes new capabilities for blade server support. The Migration Wizard has been updated and
provides better hardware swapping features.
Software requirements for server consolidation include a wide range of patterned deployments available out of the box. Currently,
the NetWare 6.5 Server Consolidation Utility 2.0 includes 15 pattern deployment options for installing specialized configuration
"templates" without administrator intervention. Some of the 15 templates include a "standard" NetWare Server optimized for file
service, iFolder Server, Apache Server, MySQL Server, LDAP Identity Server, Network Attached Storage Server, iSCSI Block Storage
Server, SilverStream Application Server, J2EE Web Services Server and iPrint Server. The custom installation option remains, because
even 100 templates would miss the special requirements for some server operations. However, clicking a pattern deployment option
saves you time and provides an excellent configuration for the specific server’s role in your network.
To make server upgrades more economical, NetWare 6.5 includes Remote Upgrade which utilizes the network connection between two
sites for all upgrade and migration functions. This allows managers to centrally upgrade geographically dispersed servers without
having to physically touch each server. A single location can provide consolidation and upgrade services for all other locations,
and accomplish these tasks in the same time frame as if you took a redeye to the remote network.
Did you notice the list of supported originating servers in the earlier list? Did you notice Windows NT on that list? Microsoft,
forced by customers to extend NT support longer than originally promised, continues to try and push customers off NT. Server
Consolidation Utility 2.0 provides an easy growth path from NT for customers with a mix of NetWare and Windows servers.
One concern in large network consolidation projects comes when managing multiple trees. Working around that problem in the past
required intensive effort by the administrator and plenty of luck to maintain a stable directory. This upgrade allows tree-to-tree
consolidations and migrations.
Moving and consolidating ownership attributes often caused surprises in the past. Files in a moved volume, owned by a user not
created in the new system, lost ownership attributes. Server Consolidation Utility 2.0 checks for orphaned users, and prompts you
to create the user in the new context or assign those rights to another user.
Requirements for Server Consolidation Utility 2.0 include a common protocol (either IP or IPX) on the originating and destination
servers, and a Windows NT/2000/XP workstation running Novell Client32. Transfer speeds depend on the LAN connections, but averages
are 2GBs per hour on a 10Mbps LAN, between 8GBs and 10GBs per hour on a 100Mpbs LAN, and between 25GBs and 30GBs per hour on a 1GB
LAN.
The joke about a "fear of commitment" came true at customer sites all over the world when forced to pass the point of no return
with earlier migration and consolidation software. Server Consolidation Utility 2.0 does not have a point of no return, because all
modifications are nondestructive. Every step in a project, even the last step, can be rolled back. When you are satisfied with your
consolidation, you accept the new network architecture.
Network change is a constant, and has been a constant headache in the past. Server Consolidation Utility 2.0 provides business
continuity and simplifies the lives of network administrators. When you know every change can be tweaked and tried again and again,
migration and consolidation projects become just another item cleared off your task list.
Novell Nterprise Branch Office
Novell Nterprise Branch Office, which ships with NetWare 6.5, is a soft appliance designed for corporations that have satellite
offices with users who require the same level of service that exists at the corporate office. That is, they need to authenticate
securely to network services, access files, print and have data protection in the event of a mishap. Nterprise Branch Office
significantly simplifies the complex task of maintaining network services at geographically distributed offices.
An Nterprise Branch Office installation consists of two parts: the branch office server, and one or more servers at the corporate
site (central office servers) to support authentication and backup. Granted, Nterprise Branch Office servers can be run in standalone
mode in the branch office, but this configuration doesn’t have the advantages of having a central office server at the corporate site,
including fault tolerance, disaster recovery and simplified directory management.
Nterprise Branch Office includes powerful authentication for secure communication between the Nterprise Branch Office appliance
and the central office server(s). This authentication provides a consistent level of security throughout the entire enterprise
network. In addition, Nterprise Branch Office allows backups to be done at the central office, relieving the worries of doing a
daily backup at the branch office. Nterprise Branch Office also utilizes automatic user-access provisioning to provide instant
access to file and print services regardless of an employee’s location. Local services, cached at the branch, provide users high
performance while reducing WAN traffic loads. (For more information on Novell Nterprise Branch Office, see Novell Connection online
at www.novell.com/connectionmagazine/2003/02/tech_talk_1.html.)
Improved cluster support
NetWare 6 included free cluster support for two servers straight out of the box. Optional licenses took the cluster up to 32 servers,
including automatic fail-over and resource migration to keep network resources available even when a server had to be stopped for
hardware maintenance.
Novell Cluster Services 1.7, which is included in NetWare 6.5, builds upon the clustering support in NetWare 6, and adds more nodes
straight out of the box. For companies truly prepared for disasters, NetWare 6.5 can be used to build business continuance clustering
solutions that fail-over an entire site to other remote sites. The other clusters may be located down the street, across town or on a
different continent.
When a site fail-over occurs, the remote clusters will pick up network resource support within seconds. You decide how many network
resources migrate when one location fails, just as you do with current cluster products. A continually failing server can now be
quarantined to reduce impact on other services. For many users, clusters mean Storage Area Networks. NetWare 6.5 cluster storage
improvements include shared readonly volumes. New backup tools and functionality improvements are discussed later in this article.
The benefits of clustering also extend to critical Web services middleware. The J2EE platform has prompted a significant amount
of standardization in Web services middleware, giving Java programmers standard APIs for common system services. These services
rely on Java Messaging Services to exchange messages through a common provider; losing that common provider derails multiple
middleware support structures and causes application failure. NetWare 6.5 provides cluster support for the jBroker Message Queue,
providing fault tolerance for middleware as well as the applications relying on that middleware.
Huge Strides In Storage Management
The name today may be "storage services," but NetWare servers have always delivered files quickly, reliably, and securely. Today’s
explosion in storage and the different types of media only increase the need for an operating system well-versed in file service.
NetWare 6 delivered a mature NSS version 3.0 able to completely replace traditional volumes in almost every case. The speed and
reliability of the journaling file system at the heart of NSS transformed large volume mounting times from many minutes to just a
few seconds. Volume capacity, whether measured in size or number of files, jumped into the terabyte range.
Storage Resource Management capabilities are now included in NetWare 6.5. Exposed in iManager and Remote Manager interfaces, these
capabilities allow administrators to track storage growth patterns by user or file type. They can even make graphs of storage usage
by either tracking method.
iSCSI Support
Internet Small Computer System Interface (iSCSI) infuses the time-proven SCSI storage interface with IP for cost advantages and
location flexibility. Using the networking standard, IP, for linking data storage units saves a considerable amount of money. Rather
than running your SAN over expensive Fibre Channel switches and connections, your standard Ethernet IP network (or a special
subnetwork in local installations) can carry storage traffic.
iSCSI takes commands for storage access and encapsulates them into IP packets. If the traffic goes over a public network,
encryption can be used for security. At the receiving end, the packet is decrypted if necessary and the storage commands extracted
from the IP packets. iSCSI provides the ability to locate storage devices anywhere, from nearby or in another country. The other
option for distance storage communications is Fibre Channel over IP, which requires Fibre Channel switches and controllers, all
of which cost considerably more than Ethernet equipment.
Novell calls iSCSI "SANs for the masses" because of the cost savings over Fibre Channel. A NetWare 6.5 cluster solution using
iSCSI makes fault-tolerant shared disk storage a reality even for small networks with limited budgets.
NetWare 5.1, NetWare 6 and NetWare 6.5 can all consume and share iSCSI storage. In addition, NetWare 6.5 can be configured as an
iSCSI disk server. With disk subsystems attached (either direct, or SAN attached), it can serve that storage to an iSCSI SAN.
Security and SAN iSCSI LUN management are all integrated with LDAP, so it is as simple as assigning servers as trustees of LUNs
in order to achieve the equivalent of LUN masking in the SAN world.
Snapshot
Experienced network administrators know that every additional storage volume means additional backup headaches. Physically moving
the data from servers to backup media (usually tape) often takes more time than you have between when the network users go home and
when they come back again. Add in the problem of supporting a distributed network with users scattered across multiple time zones
and open files continually block your backup software. Even if your software skips open files, that just means critical data in
active databases never get archived properly.
Version 6.5 has improved the Modified File List to solve that open-file problem. To handle open files, we must go below the file
system, to the storage block system, where Novell has added Snapshot at the disk block level.
Check out these new Snapshot features:
- Backup anytime
- Verify that your backup hasn’t failed
- Find and restore files using Snapshot files rather than tape backups
- Make pool-level snapshots
- Keep up to 500 active snaps of your data
- Mount any snap as its own storage pool
- Freeze and thaw interfaces for applications (such as databases and e-mail) to ensure data consistency in the snapshot
- Use the freeze and thaw software hooks available for thirdparty developers, both software applications developers and for hardware-based snapshot solution providers
The drastic drop in price for hard disk storage makes Snapshot hard disk backups as inexpensive as tapes and much more convenient.
Afternoons spent searching through backup tape index listings for an accidentally deleted file give way to a quick volume search and
restoration. In fact, you can choose among multiple file versions made during multiple snapshots to recover multiple generations of
that file. Snapshot makes such recovery not only possible, but easy. And now users can restore their own files too...
Automatic File Versioning
How many times has a user called upon IS&T to find and restore data from a backup that was accidentally deleted or modified? Usually
only once, because it typically takes IS&T much longer than the user is willing to wait. Not any longer. With Automatic File
Versioning, the Modified File List feature of NetWare 6 has been significantly enhanced to enable file-level snapshots of the
network file system. These file-level snapshots are routinely taken and are available to the end-users to view. Previous versions
can be selected and restored without having to call IS&T. Because this feature is file-based (as opposed to Snapshot which is
block-based), you can set policies such as which directories and file types are to be archived, and how often. The archive can even
be located off-site if desired. Through a Web interface (NetStorage-part of Virtual Office described below), users can find and
restore past versions on their own. Users can even browse and restore a file version from several weeks previous, or one that
another user last edited.
NAS (Network Attached Storage)
Novell Native File Access Pack brought native file access for Windows clients, Macintosh clients, Unix/Linux clients and Web clients.
Building on that capability available in NetWare 5.1, and built into NetWare 6, Novell has added improvements in NetWare 6.5.
NetWare 6.5 has the native protocols built into the NSS file system. Check out these features:
- Greater than 4GB file size support for all protocols
- Full true inter-protocol locking support
- Full international character support
- Improved performance and scalability to rival that of NetWare clients
- Support of a common authentication password with NetWare clients
- Support for password restrictions and expirations
- Support for Windows native Login command scripts
- Full Mac OS X support (AFP v3.1)
- Addition of NetWare Access Control mode for Unix/Linux (NFS)
With these features and the enterprise Novell eDirectory tied in for file services management, NetWare 6.5 offers a truly powerful
NAS solution for application servers and client workstations alike.
World’s Most Advanced Directory Services With eDirectory
The advantages of an object-oriented directory service became clear when NetWare 4.0 shipped with Novell Directory Services (NDS).
Renamed eDirectory and now up to version 8.7, directory services remains a key differentiator between Novell systems and those
following in the directory race.
After more than a decade of development, eDirectory now supports a variety of services and applications never before possible.
End-users no more see eDirectory than they see the pillars supporting their office building or the roadbed under the highway. They
just enjoy the diverse benefits of such eDirectory-enabled services as zero-day provisioning, single sign-on, login support from
any location on the network, and with NetWare 6.5, new Web services leveraging the identity services hosted by eDirectory.
Appropriately, eDirectory advancements in NetWare 6.5 hide beneath the new services and applications they support. As described
in the end-user information section below, new Virtual Office services, and especially eGuide, rely heavily on the advanced support
of eDirectory 8.7.
DirXML Starter Pack
In spite of efforts by monopolistic companies, company networks include hardware and software from multiple vendors. The DirXML
Starter Pack integration capabilities in NetWare 6.5 leverage the value of mixed environments by supporting authentication services,
identity management across eDirectory, Active Directory and Windows NT server systems environments. Out of the box, DirXML Starter
Pack can support simple password synchronization across your network and automates the process of creating, managing and deleting
user accounts and passwords among eDirectory, Active Directory and Windows NT. DirXML, one of the key components of Novell Security and Identity Solution,
improves security while providing the foundation for your complete enterprise secure identity management solution.*
