Dell EMC ScaleIO is a software only, server-side, virtual SAN storage solution that aggregates local storage capacity from physical nodes and shares it with users or applications via iSCSI. Like other scale- out, Software-Defined Storage (SDS) products, it provides the flexibility to expand capacity as needed by simply adding nodes. Each node supports a virtualization host that runs the software as a VM or ScaleIO can be run natively on a Windows or Linux server. As a component of the Open Storage Platform ScaleIO is designed to be run on industry-standard, x86-based server platforms, as described in the Evaluator Group research materials on Server-Based Storage components. In addition to internal storage devices, ScaleIO can also incorporate external, Direct-Attached Storage systems into the virtual SAN, described in the Evaluator Group research materials as well.
There are a large number of vendors that have software-defined storage products, and an even larger number that claim to be in the SDS space as well. The Evaluator Group covers over a dozen of the leading solutions, including ScaleIO, in the Open Storage Platform Software-Defined Storage Comparison Matrix and associated research materials. These include solutions from traditional storage suppliers, but also companies that may be less familiar. This Product Analysis provides details on ScaleIO, how the technology functions and what features it offers. It includes comments from the Evaluator Group about specific product details, as well as a listing of advantages and potential concerns.
