The LocalStorage API gives front-end web developers access to a simple key-value datastore that can be used to save data on a users computer. Saving data on the client-side can help to speed up the performance of your web applications as it can reduce the number of database queries that are needed on the server. This frees up valuable server resources and can potentially even lead to reduced infrastructure costs.

This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.
