Table 1-12. Cluster Storage Requirements
Hardware
Components
Minimum Requirement
Supported storage
systems
One Dell | EMC CX200 or CX400 with dual SPSs and at least five internal hard drives on the DPE.
OR
One Dell | EMC CX600 with dual SPSs and one DAE2 enclosure. At least five hard drives are
required on the first DAE2 enclosure that is attached to the CX600 SPE.
Cluster nodes The cluster nodes must be attached to a single storage system or to multiple storage systems
through a SAN using redundant fabric.
Multiple clusters and
stand-alone systems
Can share one or more supported storage systems using Access Logix, an optional software
component that is available for your storage system.
See " Storage Management Software " for information about the Access Logix software.
Table 1-13. Processor Enclosure Requirements

Enclosure
Primary Storage Secondary Storage Standby Power
Supplies (SPS)
CX200 DPE Minimum of five internal hard drives One DAE2 enclosure with a maximum of
15 hard drives
Two per processor
enclosure
CX400 DPE Minimum of five internal hard drives Up to three DAE2 enclosures with a
maximum of 15 hard drives
Two per processor
enclosure
CX600 SPE One DAE2-OS enclosure with a
minimum of five hard drives
NOTE: The CX600 SPE does not support
internal hard drives.
Up to 15 DAE2 enclosures with a
maximum of 15 hard drives
Two per processor
enclosure
NOTE: The DAE2-OS is the first DAE2 enclosure that is connected to the CX600 and has the core software (FLARE)
preinstalled on the first five hard drives.
Client Network Connections (Public Network)
The cluster connections to the public network (for client access of cluster resources) requires one or more identical NICs
supported by the system for each cluster node. Configure this network in a mixed mode (All Communications) to
communicate the cluster heartbeat to the cluster nodes if the private network fails for any reason.
Cluster Interconnects (Private Network)
Table 1-14 provides the minimum requirements for the cluster interconnects (private network).
Table 1-14. Cluster Interconnects (Private Network) Requirements
Hardware
Component
Minimum Requirement
NICs Any NIC supported by the system for each cluster node. The private network NICs must be identical and
supported by the system.
NOTE: Dual-port Fast Ethernet NICs are not recommended for simultaneous cluster connections to the public
and private networks. When configured as All Communications, the public network can provide redundancy
for node-to-node traffic in the case of a failure in the private network segment.
