However, having two types of flash in the same platform won't lead to a proliferation of all-flash arrays, Taneja said. He believes no more than 20 percent of applications have data needs that are so heavy and constant that they require all-flash storage. In most cases, SLC and MLC flash will become two more tiers within storage platforms that continue to include spinning hard disks, he said.
The new auto-tiering software will be introduced along with an SLC drive with higher capacity, moving to 400GB from the 200GB now offered in the line. Compellent's first SSD made with MLC flash will be a 1.6TB unit. Both will fit the standard 2.5-inch HDD form factor. Dell has not disclosed pricing for the SSDs. Compellent Storage Center 6.4 will be a free download for current customers.
