Note:
When you use Fibre Channel connections for mirroring, the last Fibre Channel host port on
each controller must be dedicated for communications that occur between primary volumes on one
storage array and secondary volumes on the other. If you use iSCSI connections with
Asynchronous Mirroring, these host ports are available for ordinary host connections. If you use
iSCSI connections for mirroring, any one of the iSCSI ports can be used for the mirroring
connection.
Single-controller topologies and dual-controller topologies
A controller shelf (controller-drive tray) that contains two controllers is called a duplex configuration.
A controller shelf with only one controller is called a simplex configuration. If you are creating a
topology for a simplex controller shelf, you can attach only drive trays that contain a single
environmental services module (ESM) or a single I/O module (IOM). Do not attach a drive tray that
contains two ESMs or IOMs to a simplex controller shelf.
Adding new drive shelves to an existing storage array
You can add drive shelves (drive trays) to an existing storage array without interrupting power or data
transfer to the storage array. See
Drive shelf or drive tray cabling
on page 64 for the recommended
cabling patterns for various numbers of attached drive shelves. For step-by-step instructions, see
Using SANtricity Storage Manager to add a drive tray to an existing storage array
Cabling for different management methods
When you use
in-band management, a SANtricity Storage Manager agent running on the host
receives requests from the management station. The host agent processes the requests through the
host I/O interface to the storage array. The host I/O interface might be Fibre Channel, SAS, or iSCSI.
InfiniBand host interfaces do not support in-band management.
