Introduction 11
Table 1-3 lists hardware requirements for the disk processor enclosures DPE
DAE, and SPS.
NOTE: Ensure that the core software version running on the storage system is
supported by Dell. For specific version requirements, see the Dell Cluster
Configuration Support Matrices located on the Dell High Availability Cluster website
at dell.com/ha.
Supported Cluster Configurations
Direct-Attached Cluster
In a direct-attached cluster, all nodes of the cluster are directly attached to a
single storage system. In this configuration, the RAID controllers (or storage
processors) on the storage systems are connected by cables directly to the
Fibre Channel HBA ports in the nodes.
Figure 1-1 shows a basic direct-attached, single-cluster configuration.
