free vs commercial Unix
First off, I apologize for making my first post here a question that has probably been asked over a billion times... however with the ever changing nature of technology, it almost seems like yesterday's answers are no longer applicable.
Basically I am looking to start up a business and am trying to figure out what OS is best for me. I definately want to use Unix over Linux as I am more familiar with Unix. I am not an experienced Unix admin however I am reading as much as I can to try to get up to speed.
My business will be running its own servers for DNS/web/database/proxy-cache/email/etc. I would like if possible to use a single common OS throughout all the servers to make administration easier. I am prepared to buy Sun servers if necessary to run Solaris, or IBM servers to run AIX, etc etc... I also am willing to purchase servers and load FreeBSD/netBSD/OpenBSD on it. What it really comes down to though is power/stability/security/flexibility. I want whatever is the best OS for the job.
I was originally thinking of going with Sun servers running Solaris, however I have gotten many mixed messages regarding whether this is a good idea or not. Most people seem to say that FreeBSD is the best for my purposes and that Solaris's advantage is mainly the ability to run Oracle and to hot-swap CPU's, etc.
Being that I am fairly new to the Unix world, I don't have a preference, and am willing to learn whatever I get. I just am trying to make a more educated decision regarding which Unix is the best for me.
So any help that you guys could offer in aiding my decision would be much appreciated. What are the benefits of each OS, vs the cons of each OS? Is the main draw of FreeBSD that it is free? Etc etc.
Thanks

Hi All,
I was wondering how come major router vendors (e.g C**CO ) use

Isn't it a disobedience to the GPL licence ?

NAME
dhcp_modules - data storage modules for the DHCP service
DESCRIPTION
This man page describes the characteristics of data storage modules (public modules) for use by the Solaris Dynamic Host Configuration Pro-
tocol (DHCP) service.
Public modules are the part of the DHCP service architecture that encapsulate the details of storing DHCP service data in a data storage
service. Examples of data storage services are NIS+, Oracle, and ufs file systems.
Public modules are dynamic objects which can be shipped separately from the Solaris DHCP service. Once installed, a public module is visi-
ble to the DHCP service, and can be selected for use by the service through the DHCP service management interfaces (dhcpmgr(1M), dhcpcon-
fig(1M), dhtadm(1M), and pntadm(1M)).
Public modules may be provided by Sun Microsystems, Inc or by third parties.
The Solaris DHCP service management architecture provides a mechanism for plugging in public module-specific administration functionality
into the dhcpmgr(1M) and dhcpconfig(1M) utilities. This functionality is in the form of a Java Bean, which is provided by the public module
vendor. This Java Bean collects public module-specific configuration from the user (you) and provides it to the Solaris DHCP service.
The Solaris DHCP service bundles three modules with the service, which are described below. There are three dhcpsvc.conf(4) DHCP service
configuration parameters pertaining to public modules: RESOURCE, PATH, and RESOURCE_CONFIG. See dhcpsvc.conf(4) for more information about
these parameters.
SUNWfiles
This module stores its data in ASCII files. Although the format is ASCII, hand-editing is discouraged. It is useful for DHCP service envi-
ronments that support several hundred to a couple thousand of clients and lease times are a few hours or more.
This module's data may be shared between DHCP servers through the use of NFS.
SUNWbinfiles
This module stores its data in binary files. It is useful for DHCP service environments with many networks and many thousands of clients.
This module provides an order of magnitude increase in performance and capacity over SUNWfiles.
This module's data cannot be shared between DHCP servers.
SUNWnisplus
This module stores its data within a NIS+ domain. It is useful in environments where NIS+ is already deployed and facilitates sharing among
multiple DHCP servers. This module suports several hundred to a few thousand clients with lease times of several hours or more.
The NIS+ service should be hosted on a machine with ample CPU power, memory, and disk space, as the load on NIS+ is significant when it is
used to store DHCP data. Periodic checkpointing of the NIS+ service is necessary in order to roll the transaction logs and keep the NIS+
service operating at its highest efficiency. See nisping(1M) and crontab(1) for more information.
