• pxelinux.cfg if the node is booting from the network

In the configuration file, a kernel parameter named castor_net is included in the append clause.

castor_net enables you to specify both the bonding mode for the adapters as well as a comma-

separated ordered list of the network devices that DX Storage can use, where the first device in the

list is the preferred interface that will be used whenever it is on-line.

The list of network devices must utilize the adapter names assigned by DX Storage. To find the

current list of adapter names and MAC addresses, hold down the Shift key while booting a node and

enter utility at the prompt.

DX Storage assigns device names to adapters based on a sorted list of MAC addresses. Device

names begin with eth followed by an integer starting at 0. Adding network hardware can change the

assignment order.

Some examples follow. The other portions of the append clause have been abbreviated for clarity.

Note the trailing colon after the bonding mode:

append initrd=...

2.7. Proxying the Admin Console

Administrators running DX Storage on a private, protected network may wish to allow clients on

the external network to view the DX Storage console without also providing them access to the

nodes themselves on the private network. This can by accomplished by proxying the console from

a privileged server that straddles the internal and external networks. For instance, from a server

running Apache, the following rewrite rule for URLs could be applied via the mod_rewrite module:

RewriteEngine

RewriteRule

^.*/storage/([^/]+)/(.*)$

http://$1:90/$2 [P,L]

</Location>

Please reference the

Managed switches commonly make use of IGMP snooping in order to direct multicast traffic to

their ports. By default, DX Storage uses IGMPv2 responses to host membership queries. The

igmpVersion parameter can be used to force the use of version 1, 2, or 3.
