EnterpriseStorageForum.com posted an introduction to clustered file systems last week that you may be interested in perusing if storage is a source of fear and confusion for you. I’m in a twelve step program to get over my own storage fears.
Many options exist for setting up clustered and highly available data storage, but figuring out what each option does will take a bit of research. Your choice of storage architecture as well as file system is critical, as most have severe limitations that require careful design workarounds.
In this article we will cover a few common physical storage configurations, as well as clustered and distributed file system options. Hopefully, this is a good starting point to begin looking into the technology that will work best for your high availability storage needs.
