Discovering And Managing Your Storage
Array
You can manage a storage array in two ways:
• Out-of-band management
• In-band management
Out-Of-Band Management
In the out-of-band management method, data is separate 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. By default, 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 your
system’s Deployment Guide at dell.com/support/manuals.
When you add storage arrays by using this management method, specify only the host name or IP
address of the host. After you add the specific host name or IP address, the host-agent software
automatically detects any storage arrays that are connected to that host.
NOTE: Some operating systems can be used only as storage management stations. For more
information about the operating system that you are using, see the MD PowerVault Support Matrix
at dell.com/support/manuals.
