Storage is essential for the enterprise: Data must be stored. Data must be retrieved. Data must be shared. Data must be secured. At the same time, storage must not consume the entirety of your IT budget. Fortunately, you can find effective solutions in the world of open source.
Outside of cost effectiveness, one of the biggest benefits of these solutions is the ability to modify them to perfectly fit your needs. You can make minor changes or even roll your own storage solution based on one of these tools.
If you want enterprise support and a "solution in a can" that will meet just about any enterprise storage need, you should turn to Red Hat or SUSE. Both Linux-based companies offer some of the most powerful enterprise-ready tools on the market. But if you'd rather get your hands dirty and craft something of your own—something that won't demolish your budget—these five open source tools are a great place to start.
