The Ready Stack physical rack layout is flexible and depends on many data center elements such as power, thermals, and weight restrictions. PowerEdge rack servers require either 1U or 2U of rack space, depending on the model, and the compute server quantity can change depending on customer needs.
The Dell EMC Unity XT x80 storage arrays are the latest release in the Unity family of unified storage products that offers integrated block, file, and advanced data services. New features include: More memory, more processing power, 25 GbE I/O support, larger capacity drives with non-volatile memory express (NVMe) support, data services including inline data reduction, and enhanced replication. These features contribute to performance and efficiency increases from the previous generation of up to two and three times, respectively.
Unity XT x80 storage can require fewer or additional disk enclosures, depending on the storage capacity and solid-state drive (SSD) type. Additional items such as Dell EMC Integrated Data Appliance (IDPA) can also be included within the same rack, space permitting. Ready Stacks are sized in Enterprise Small, Medium, and Large configurations. The following figure is an example of the Enterprise Medium configuration:
