DAS/SAN Product Offerings

Dell | EMC products are the highest performance storage offerings available through Dell, relying upon industry leading technology to meet the most demanding Enterprise storage needs. There are currently three different Dell | EMC DAS/SAN options available, and one NAS option. These products cover a range of price and performance, allowing businesses to select the appropriate solution for the application. All Dell | EMC products use Fibre Channel technology (they use the FC-AL topology internally) for high performance and reliability.
