A major selling point of innovative cloud infrastructure is limitless scalability. Ironically, once an organization hits mega scale, economics could send them hurtling back from advanced all-flash storage to more old-school methods. “The all-flash array movement is great for certain workloads,” said Erik Kaulberg (pictured, right), senior director of cloud solutions at Infinidat Inc. However, companies should think carefully about whether their workloads belong to that category before they invest, he added. “For 80 to 90 percent of common data center environments, it’s just a way to make storage expensive again,” Kaulberg stated.
