Connecting the Storage Array
The storage array is connected to a host using two hot-swappable RAID
controller modules. The RAID controller modules are identified as RAID
controller module 0 and RAID controller module 1.
For more information, see the
Getting Started
Guide.
Each RAID controller module has four SAS In port connectors that provide
SAS connections to the host or node. Each RAID controller module also
contains an Ethernet management port and a SAS Out port connector. The
Ethernet management port allows you to install a dedicated management
station (server or stand-alone system). The SAS Out port allows you to
connect the storage array to optional expansion enclosures for additional
storage capacity. For more information, see the
Getting Started
Guide
.
Each Dell PowerVault MD3200 series storage array can be expanded to a
maximum of 120 (or 192, if enabled through the Premium Feature activation)
physical disks through a maximum of seven PowerVault MD1200 series
expansion enclosures.
NOTE: When you connect a host server to a storage array SAS In port connector,
any Out port connector of the server's host bus adapter (HBA) can be used.
Cabling the Storage Array
You can cable the storage array to host servers with:
• Single path data configuration—A single path configuration allows you to
connect a maximum of eight hosts. This is a non-redundant configuration.
• Dual path data configuration—A dual path configuration allows you to
connect a maximum of four hosts.
Choose the data configuration based on:
• Number of hosts required
• Level of data redundancy required
