the controllers. The maximum number of logical drives that are supported by the host
operating system can be configured and used.
The storage system can be managed when there are problems with the Fibre Channel
links.
Security is enhanced when management LANs/VLANs and more advanced solutions,
such as VPN, can be used to manage the system remotely.
You can use one DS Storage Manager client to manage more than one DS3500 storage
subsystems in the network.
Managing storage systems using the direct (out-of-band) management method has the
following disadvantages:
Two Ethernet cables are required to connect the storage system controllers to a network.
When adding devices, the IP address or host name for each controller must be provided.
DHCP/BOOTP server and network preparation tasks are required. This can be avoided by
assigning static IP addresses to the controller, or by using the default IP address.
Note: To manage storage subsystems through a firewall, configure the firewall to open port
2463 for TCP and UDP data.

4.7.2 In-band management

When you use the in-band management method (also known as the host-agent method), the
DS3500 storage system is managed through the host I/O connections to the host server (see
Figure 4-20). You must install the Storage Manager agent (SMagent) software on each host
server that you want to configure for in-band management. You can use the host server as the
management station, or you can use a dedicated management station that connects to the
host server over a network connection.
Note: In-band management is not supported with all of the possible combinations of
operating system and host bus adapters. You should always refer to the latest DS Storage
Manager documentation for information about any in-band limitations or restrictions that
are associated with your particular combination of controller, operating system and host
bus adapter.
