8. Controller-drive tray for the storage array
When you use out-of-band management , the storage management station is connected through an
Ethernet network to each of the controllers in the controller shelf or controller-drive tray. E2800
controller shelves can use out-of-band management with SANtricity System Manager. E2800
controller shelves might also use the SANtricity Storage Manager Enterprise Management Window
(EMW) with either management method. Out-of-band management is an optional alternative to in-
band management for all other models of controller-drive trays.

9. Ethernet cable from the controllers to the ethernet network
With out-of-band management, a Dynamic Host Configuration Protocol (DHCP) server is
recommended for assigning IP addresses and other network configuration settings. A DHCP server
provides the network administrators the ability to manage and automatically assign IP addresses. If a
DHCP server is not used, you must manually configure the controllers. For more information, see
SANtricity Power Guide for Advanced Users for your operating system or the "Adding a Host or
Storage Array" online help topic in the Enterprise Management Window.
Attention: Risk of unauthorized access to or loss of data – If you use the out-of-band
management method, connect the management Ethernet ports on the controllers to a private
network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your
storage array might be at risk of being accessed from outside of your network.
