The Dell EMC DD6400 appliance comes with set of 8 8TB hard drives in its base model. This provides up to 32 TB of storage for active tier and cloud tier.

A main advantage of DD6400 is that there is no need to add a separate storage shelf to configure the cloud tier. Capacity is licensed up to a maximum of 32 TB for active tier and 64 TB for cloud tier in the base configuration. It also has a pair of SSDs for DDOS and two additional SSDs for system cache. The first cache disk is available in the base model. The second cache disk is added when the customer adds the first expansion shelf.

For networking, there are four slots for Ethernet and one slot for Fiber channel. A network daughter card is required, either a four port 10Gb BASET or a four port 10Gb SFP+ card.

DD6400 has up to three optional Ethernet slots for any combination of four port 10GbE BASET, four port 10GbE SFP+, or two port 10/25 Gb card. Fiber channel is also an option, and can use two port 16GB FC.

DD6400 has a single SAS card, with dual path for an expansion shelf.
