How the leading all-flash array vendors meet storage demands

Here, we will examine products from the eight leading all-flash array vendors -- #DellEMC, #Hitachi Data Systems Corp., Hewlett Packard Enterprise ( #HPE ), #IBM, #Kaminario Inc., #NetApp Inc., #PureStorage Inc. and #Tegile Systems Inc. Note that all of the all-flash array vendors offer compression and deduplication. These technologies, when combined, can provide up to a 100 times or greater reduction in data. For instance, a system storing 100 virtual machine virtual drives may have more than 95% of the data from each image duplicated in all 100 images, resulting in a nearly 100 times reduction with deduplication. On the other hand, an encrypted, compressed video file may not benefit from either deduplication or compression. When possible, we have listed the raw capacities of the systems; when those were not available, we noted the claimed effective capacity, which is usually three to five times the raw capacity. Some vendors guarantee the effective capacity.
