Setting Up Hardware Virtual Servers for ISPs
If you need servers that respond to different IP addresses and require that they
have separate configuration information, install separate instances of the server
with specific IP addresses. For more information, see “Adding a Server: Running
Multiple Servers” on page 60.
Unix. Before you set up hardware virtual servers, make sure you specified a
specific bind-to-address for your server in the Network Settings page (from the
Enterprise Server, choose Server Preferences and then click Network Settings).
If you left the Bind To Address field blank, you may experience errors when
using hardware virtual servers. If you are an ISP using hardware virtual servers,
the bind-to-address should be your main IP address.
You can set up hardware virtual servers through the Hardware Virtual Servers
page in the Server Manager. For more information, see the online help.
Setting Up Hardware Virtual Servers for ISPs
ISPs that need to support more than 256 IP addresses or that want the server to
use less memory can use the ISP-version of the hardware virtual server
function. As with default hardware virtual servers (discussed in the previous
section), ISP-version hardware virtual servers allow you to configure your
server to respond to multiple IP addresses without installing multiple servers,
but you can configure your server to support an arbitrary number of IP
addresses.
ISP-version hardware virtual servers share the same server configuration
information. For example, if you turn on encryption for one hardware virtual
server, any other hardware virtual servers you create would also have
encryption turned on. If you need servers that respond to different IP addresses
and require that they have separate configuration information, install separate
instances of the server with specific IP addresses. For more information, see
“Changing Network Settings” on page 68.
For HP servers, the number of virtual servers must work well with the
max_thread_proc
entry in the HP-UX kernel and
RqThrottle
. Since
threads are never “released,” but moved to another pool, the number of threads
used can get quite high when using hardware virtual servers in the object
model. For more information, see “About RqThrottle” on page 229.
