We are beginning talks with our IT department and management about switching from the google search appliance to Solr. One thing that we need to figure out is what kind of hardware we are going to require to host the Solr systems.
What type of hardware (at a high level) should I be looking for. Are the main constraints disk I/O, memory size, processing power, etc...? Right now we have about 183 documents stored in the GSA (which will go up a lot once we are on Solr since the GSA is limiting). The search systems are used to display core information on several of our homepages, so our search traffic is pretty significant (the GSA reports 5,683 searches in the last month, however I am 99% sure this is not correct and is not counting search requests without any search terms, which consists of most of our search traffic). Thank in advance.
