Network interface cards
A network interface card (NIC) is an expansion board that is installed in the host server. Some
servers are equipped with an integrated NIC. The NIC supports Ethernet technology. The NIC is
required for network communication. Each Ethernet cable connection for out-of-band storage array
management is made through an NIC.
Note:
If your configuration requires a host Ethernet connection through an NIC, you must obtain
and install the required NICs.

Switches and zoning
A switch is an intelligent device that connects multiple devices. A switch allows data transfer
between the devices, depending upon the designated source (
initiator ) and the destination (target ) of
the data. A switch provides full bandwidth per port and high-speed routing of data.
Zoning allows a single hardware switch to function as two or more virtual switches. In a zoned
configuration, communication among devices in each zone is independent of communication among
devices in another zone or zones. Zoned switches allow an administrator to restrict access to specific
areas within a storage area network (SAN).
In-band management and out-of-band management
You can manage a storage array from a storage management station, which is a workstation on which
the SANtricity Storage Manager Client is installed. Requests and status information sent between the
storage array and the storage management station are managed in one of two ways: in-band or out-of-
band. A storage array that uses out-of-band management requires a different network topology from
a storage array that uses in-band management.
For in-band management, requests and status information are communicated through the same
connection that is used to write data to and read data from volumes in the storage array. For out-of-
band management, requests and status information are communicated through a separate Ethernet
connection between the management station and the storage array.
You can manage an E2800 or E5700 storage array through the SANtricity System Manager.
SANtricity System Manager has a web interface that is available through any supported browser on a
system that can access an E2800 or E5700 controller through an Ethernet network. This is an
example of out-of-band management. You might also use the SANtricity Storage Manager to manage
an E2800 or E5700 storage array through the Enterprise Management Window (EMW) using either
in-band or out-of-band management.
Best practices
To make sure that your cabling topology results in optimal performance and reliability, familiarize
yourself with cabling best practices. If your existing storage array cabling does not comply with the
best practices described in this section, do not re-cable your storage array unless specifically
requested to do so by technical support.
Drive shelf cabling for redundancy
When you attach the drive shelves (drive trays), to a two-controller (duplex) controller shelf
(controller-drive tray), use a cabling topology that does not create a single point of failure. A single
point of failure might appear as a drive shelf failure or another component failure in the middle of a
series of drive shelves. If a drive shelf fails, you can no longer access the drive shelves beyond the
