When the EMC CLARiiON CX4 was launched in 2008, storage industry experts noted that, despite the array’s lower price tag, it effectively blurred the lines between EMC’s flagship enterprise-level Symmetrix and the mid-line Clariion CX series systems. The CX4 rolled out in four different configurations; CX4-120, CX4-240, CX4-480, and the top of the line CX4-960. In each, the three digit model number denotes the number of drives it can support. For example the CX4-960 can take up to 960 X 2TB HDDs with a maximum system capacity of 1899 TB, nearly equal to the maximum capacity of the Symmetrix line.

Since the differences between full SSD and hybrid systems are fairly well defined, the choice of going either route is usually relatively black and white. If having the lowest latencies and response times and the highest IOPS and throughput are absolute must-haves right now, then going 100 percent SSD will benefit your organization more. Otherwise, a slow and steady transition to SSD via the hybrid route and taking advantage of lower future NAND prices might be a better way to go. Fortunately, both of these adoption strategies are available to storage architects in the context of legacy EMC storage hardware. Most EMC controllers & systems have supported SSD technology since it first became available on their Symmetrix line. The technology eventually made the leap devices for small- and medium-sized businesses, including its CX4 storage area network series.
