Virtualization is an alternative as well. We run Nagios and Cacti on one server and four instances of Splunk on four other servers. Last month, we used VMWare's P2V tool to make all five physical servers virtual, then moved them to a a Sun X4100 running ESXi. The only cost was the server. The overall load of each individual virtual server is under 50% and the ESXi box itself is sitting at only 30% load. If disk space is an issue, another alternative is to clone the HD(s), then perhaps move to another server (in the case of going to IDE or SATA to SAS or SCSI, this is likely a must). <pre class="moz-signature" cols="72"> A.
