    <p>As a proof of concept kind of project, I have set up a sharded MongoDB, with only two shards, and three servers running mongos instances. All of these are on their own Windows servers, but I'd like to try running the cluster on Linux systems, because I'm seeing some strange behaviour that I think <em>may</em> be related to the fact that the systems are all running on VMs on a corporate ESX server. Also, I'm just curious.</p> <p>After reading as much documentation as I could find, I've found that the "mongos" instances that dispatch queries to the proper shards are lightweight and can typically be run on an application server or a system with a mongod instance (<a href="http://docs.mongodb.org/manual/tutorial/deploy-shard-cluster/#start-the-mongos-instances" rel="nofollow" title="documentation">documentation</a>).</p> <p><strong>My question is</strong>, can MongoDB be configured so that the <strong>mongos</strong> instances run on a Windows server, while the <strong>mongod</strong> instances (the shards) be run on a Linux system? Would the <strong>mongos</strong> instances still be able to dispatch queries to the Shards?</p> <p>One reason this would be beneficial in my case is that my application is a .Net web API, that I want to host in IIS, so it has to run on Windows. The benefit to running shards on Linux, which may be an incorrect assumption, is that a Linux system requires less overhead than Windows server, meaning it would be less expensive if it were run on a VM from a cloud provider.</p>

    2. COThe only problems I can foresee are the headaches you'll most likely get when trying to maintain these systems :P Other than that, @Sammaye is correct: It doesn't matter as long as the instances are able to communicate with each other. IE correct IP's, ports, firewall setup, etc...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
