Owners Manual

Dell Integrated Systems for Oracle Business Analytics (DISOBA) – Owner’s Guide 1.0
networks over two cards, we are able to eliminate the possibility of a downed card
resulting in lost communication.
The public interfaces are in Linux bonded mode 1, which is an active-backup
configuration. This means that if a single public interface loses connection, there is always
an alternate path that takes over to ensure continuous communication.
NOTE: The public network interface is not pre-assigned with an IP address and requires to
be assigned at the customer’s site.
The private interfaces are not bonded at the OS level since the recommendation is to
utilize Oracle’s HAIP, which places two separate physical links on different subnets,
ensuring that there are two distinct paths for data to travel on. HAIP is a feature of Oracle
Grid Infrastructure installation, and requires at least two interfaces on separate private
subnets to be configured. The following two private interface network scripts are pre-
configured at the OS level:
1. Oracle Private A: /etc/sysconfig/network-scripts/ifcfg-eth5
2. Oracle Private B: /etc/sysconfig/network-scripts/ifcfg-eth7
NOTE: Refer to Table 4 for the pre-assigned IP addresses for the private interfaces
During Oracle grid installation select the above two pre-configured network interfaces for
the private interconnect.
4.4 Management Server (R320) Configuration
The management server (MS) is pre-installed with Oracle Linux 6.5 running the Red Hat
Compatible Kernel. The MS ships with the following pre-configuration:
 As an isolated and contained DHCP and TFTP Server
o This ensures the IP address for the private rack network components, e.g.
iDRAC and private management port on the servers and management
ports on the switches is static and consistent across reboots. This is
achieved by pre-configuring the/etc/dhcpd/dhcpd.conf file with the
MAC addresses of these network ports.
o This allows to easily upgrade the firmware or apply pre-configured switch
settings on the S6000 and the S60 switches by booting them in
jumpstart mode. Though this feature is available, customers are not
recommended to upgrade or change the switch settings without
consulting with Dell Support.
o DHCP is configured to always use rack private network so that it does not
cause any conflict with customer’s DHCP server. DHCP is setup to use
bond0 private adapter on the MS for servicing all DHCP requests.
o To quickly access and manage DISOBA components, on the management
server Desktop, shortcuts to the iDRAC sessions are created for each
component.
