Dell CX4 Series - Cluster Storage

10 Introduction
Cluster Storage
Table 1-2 lists supported storage systems and the configuration requirements
for the cluster nodes and stand-alone systems connected to the storage systems.
Table 1-3 lists hardware requirements for the storage processor enclosures (SPE),
disk array enclosures (DAE), and standby power supplies (SPS).
NOTE: The DAE-OS is the first DAE enclosure that is connected to the CX4-series
(including all of the storage systems listed above). Core software is preinstalled on
the first five hard drives of the DAE-OS.
