E-Series hardware overview

E-Series storage arrays are available in several configurations and models.

A storage array includes shelves, controllers, drives, software, and firmware. The array can be installed in a rack or cabinet, with customizable hardware for one or two controllers, in a 12-, 24-, or 60-drive shelf. You can connect the storage array to a SAN from multiple interface types and to a variety of host operating systems.

E-Series arrays are available in the following models:

E2800 series – entry-level hybrid
EF280 series – entry-level all flash
EF300 series – entry-level all flash, all NVMe
E5700 series – midrange hybrid
EF570 series – midrange all flash
EF600 series – midrange all flash, all NVMe
