IP PBXs built on open source software show promise
In this Clear Choice test of four open source-based IP PBX systems, we found products that are well suited for the low end – defined in this testing as supporting as many as 250 concurrent users. By providing simple installation processes, automatic endpoint configuration and straightforward Web-based management interfaces, these products could go a long way in easing IT fears about dealing with open source VoIP products.

RAID technology – Redundant Array of Independent Disks – lets you establish varying degrees of data protection depending on the particular requirements of a given application. RAID levels 0, 1, 5 and 10 have been the most widely used, with RAID 5 (rotational parity) reigning supreme for fault tolerance because it allows data on a failed drive to be rebuilt without losing accessibility to stored information. RAID 6 (double parity) provides a higher level of fault tolerance by protecting data on two drives in the event of a failure.
