How many DAE Row Controllers are present within the DAE chassis of an XtremIO X2 cluster?

In an XtremIO X2 cluster, the Disk Array Enclosure (DAE) chassis typically contains two Row

Controllers. These Row Controllers are responsible for managing the operations of the SSDs within

the DAE and ensuring data availability and integrity. The design of the DAE in an XtremIO X2 cluster is

such that it provides a balance between performance, redundancy, and cost-effectiveness, with two

Row Controllers being a common configuration for managing the SSDs effectively.

Reference:

The Dell XtremIO Design Achievement document provides information on the critical components of

the XtremIO and X2 systems, including the DAE chassis and its controllers1.

Additional details on the architecture and components of the XtremIO X2 systems can be found in

the Introduction to XtremIO X2 Storage Array white paper2.
