IBM DS3500

Important:
1. To minimize security risks, do not connect the DS3500 to a public LAN or public
subnet. Use a local private network for the DS3500 and the management
station Ethernet connectors.
2. For proper EMI shielding, always use quality braided and shielded serial cables.
Connect an Ethernet cable from the management station to the Ethernet connector
on controller A on the rear of the storage subsystem. For a dual-controller storage
subsystem, you can connect a second Ethernet cable from the management station
to the Ethernet connector on controller B. Figure 40 shows the locations of the
Ethernet management connectors on the DS3500 storage subsystem.
Configuring the storage subsystem
You must configure the storage subsystem after you install the storage subsystem
in a rack. Use the information in the following sections to configure your storage
subsystem.
Storage subsystem management methods
Before you configure the storage subsystem, determine which method of storage
subsystem management you want to use. You can manage the storage subsystems
in either of two ways: host-agent (in-band) management or direct (out-of-band)
management.
Note: For information about any in-band limitations or restrictions that are
associated with particular combinations of controller and host bus adapter,
see the DS Storage Manager readme file.
For more information about setting up in-band or out-of-band management
connections, see the DS Storage Manager 10 Installation and Host Support Guide
for the operating system of the host server that you will use to manage the DS3500
storage subsystem. The document is in the Documentation folder on the IBM
System Storage DS3500 Support DVD.
Important: If the operating system of the host server that the storage subsystem
logical drives are mapped to is not Microsoft Windows Server 2003 or
Windows Server 2008, you must make a direct (out-of-band)
management connection to the storage subsystem to set the correct
host type first. Then, the server will be able to recognize the storage
subsystem correctly for host-agent (in-band) management.
Host-agent (in-band) management method: This method requires that
host-agent software be installed on the host server. The host-agent software
enables the DS Storage Manager software client program to manage the storage
subsystem by using the same connections between the host server and the storage
Ethernet ports
