<includeonly>===Adding Additional memcached Servers===</includeonly>
Adding an additional memcached servers helps to distribute the cache and balance the load across the memcached servers.

;To add an additional memcached server:
# Edit [[networking.properties]] on all instances.
# Update the <tt>MemCachedServers</tt> entry 
# Restart all servers, following the [[Server Restart Sequence]]<br/>''Note:'' The sequence is important!

;Example:
There is one memcached server running on serverA (192.168.0.1) on port 11211.
On each instance, the <tt>networking.properties</tt> has this:
{|
<pre>
MemCachedServers=192.168.0.1:11211
</pre>
|}

A second memcached server is brought up on serverB (192.168.0.2) on port  11211. 
The <tt>networking.properties</tt> file is edited on all instances so it looks like this:
{|
<pre>
MemCachedServers=192.168.0.1:11211 192.168.0.2:11211
</pre>
|}
<noinclude>

[[Category:Installation]]
</noinclude>
After following the [[Server Restart Sequence]], all instances are using the new, distributed cache.

If a 3rd memcached server is added (192.168.0.3), the <tt>networking.properties</tt> file will look like this:
{|
<pre>
MemCachedServers=192.168.0.1:11211 192.168.0.2:11211 192.168.0.3:11211
</pre>
|}

Again, the [[Server Restart Sequence]] is followed to enable the new configuration.
