Configuration: About Your Storage
Array
You can manage a storage array in two ways:
• Out-of-band management
• In-band management
Out-of-Band Management
Using the out-of-band management method, data is separated from commands
and events. Data travels through the host-to-controller interface, while
commands and events travel through the management port Ethernet cables.
This management method lets you configure the maximum number of
virtual disks that are supported by your operating system and host adapters. A
maximum of eight storage management stations can concurrently monitor an
out-of-band managed storage array. This limit does not apply to systems that
manage the storage array through the in-band management method.
When you use out-of-band management, you must set the network
configuration for each RAID controller module’s management Ethernet port.
This includes the Internet Protocol (IP) address, subnetwork mask (subnet
mask), and gateway. If you are using a Dynamic Host Configuration Protocol
(DHCP) server, you can enable automatic network configuration, but if you are
not using a DHCP server, you must enter the network configuration manually.
NOTE: RAID controller module network configurations can be assigned using a
DHCP server (the default setting). However, if a DHCP server is not available for 150
seconds, the RAID controller modules assign static IP addresses. The addresses
assigned are 192.168.128.101 for controller 0 and 192.168.128.102 for controller 1.
In-Band Management
Using in-band management, commands, events, and data travel through the
host-to-controller interface. Unlike out-of-band management, commands and
events are mixed with data.
NOTE: For detailed information on setting up in-band and out-of-band management
see the Deployment Guide.
