What is the design concept of the XtremIO X2-S X-Brick configuration?

The Dell XtremIO X2-S X-Brick configuration is specifically designed and optimized for workloads that yield high data reduction ratios, such as Virtual Desktop Infrastructure (VDI) and copy data management (CDM). Its primary design concept is to maximize the logical capacity (also known as effective capacity) from a given amount of physical storage. By leveraging XtremIO's powerful inline, always-on deduplication and compression, the X2-S model provides a cost-effective solution for environments where data is highly redundant, thus achieving a high logical-to-physical capacity ratio.

A. High disaster risk reduction is a function of data protection and replication software (e.g., RecoverPoint for Virtual Machines), not the intrinsic hardware design concept of the X2-S model.
B. High fault tolerance is a core characteristic of the entire XtremIO platform through its XtremIO Data Protection (XDP), not a specific design differentiator for the X2-S configuration versus other models.
C. The X2-S is the smaller of the two X2 configurations and is not designed for the highest possible physical capacity; that role is typically filled by larger configurations or different array types.

1. Dell EMC XtremIO X2 Storage Array Data Sheet. (2019). Page 2, "XtremIO X2 Models" section. The document states, "XtremIO X2-S is optimized for high logical capacity use cases such as VDI and copy data management (CDM)." This directly confirms that the design concept is centered on maximizing logical capacity.

2. Dell EMC XtremIO X2: Architectural Overview. (2017). H16247.1. Page 6, "XtremIO X2 Hardware" section. This white paper describes the two X-Brick models, highlighting that the X2-S is the entry-level model, which, combined with its target workloads (VDI), reinforces its focus on data reduction efficiency and logical capacity rather than raw performance or physical size.
