Are there any real changes in NLB on Svr2008?

Any articles anywhere? I have searched but nothing much shows up.

Thanks,

BB

NLB is not installed by default on Svr2008 - you have to install and
configure it yourself.

There seems to be a new dedicated NLB configuration wizard instead of
an MCC plugin.

Biggest change is in security with the implementation of Internet
Protocal security layer.



Microsoft's new features writeup for svr2008 states:

Network Load Balancing (NLB) allows you to distribute TCP/IP requests
to multiple systems in order to optimize resource utilization,
decrease computing time, and ensure system availability. NLB has been
improved in Windows Server 2008, including:

Next Generation TCP/IP
The TCP/IP protocol suite has been completely redesigned for Windows
Server 2008. Internet Protocol version 4 (IPv4) and Internet Protocol
version 6 (IPv6) are both supported natively by Windows Server 2008.
NLB extends full support to IPv6 for all communication while
maintaining IPv4 support.

Multiple IP Address Support
Each node in your NLB cluster can now have multiple dedicated IP
addresses.

Microsoft ISA Server Integration
Microsoft ISA Server can support your mixed IPv4 and IPv6
infrastructure by allowing multiple IP addresses for each NLB node
where IPv4 and IPv6 clients are used. ISA Server can also provide
intrusion detection services to protect your NLB cluster.


You sound like someone who has had experience with NLB. Is it
possible to setup IIS servers in an NLB configuration on a multi-
processor machine? Can this be done?

Thanks for the notes. I must look for that info on the MS site.

About NLB. It has nothing to do with setting up multiple sites, for whatever
reason, on ONE machine. The purpose of NLB is to balance load accross
hardware i.e. two or more machines. This also provides the additional
benefit of resiliance in that if one server goes down then the others take
over unknown to your site visitors.

If your applications are used intensively you can assign more than one
worker process to an application pool and you can separate your applications
in their own app pool. That is the best way to make the most of your
hardware. You may be able to bind an app pool/worker process to a processor
on a multi processor machine but that may not be helpful.

One thing that's changed in IIS 7.0 is the default use of kernel mode
authentication.

I've described how it works, why it's different, and how to disable it (for
NLB scenarios) here:
