Built-in NIC port 1 Networks used with HP X5500 Storage Gateway for Linux should be configured as follows: • Each network be set on each network interface: Broadcast, Multicast, Up, Running. Each server has five Gigabit Ethernet connections that are to be used for data (NFS) - HP ProLiant DL380G5-WSS | HP StorageWorks X5500 Network Storage Gateway for Linu - Page 11
The iLO plays an integral part in the HP X5500 Storage Gateway for Linux solution. It is used to restart a server in the cluster if the server is not adhering to the rules of cluster guidelines on page 6 for more information.
