In a star cluster, he says, every node is connected to the other via a single switch. In a grid, there are multiple paths between nodes through smaller switches. From a technical perspective, the term grid is well understood, but tack on the word "storage" and you immediately get confusion.

Modern storage arrays offer disk types to meet any need -- costly Fibre Channel (FC) disks for high-end applications requiring superior performance and availability, and lower-priced SATA disks for less-critical data. The arrays also come with mixed RAID configurations. But selecting the right mix of disks and RAID levels requires understanding the impact of those decisions.
