Owners Manual

NOTE: It is recommended to use an MTU of 1500 for the cache network.

NOTE: Do not use a network adapter driver downloaded from the manufacturer’s site. Fluid

Cache uses a custom driver available only through Dell.

3. Create and configure an IP address on all RoCE network interfaces that are connected:

a. Open the interface configuration file by running the commands:

cd /etc/sysconfig/network-scripts

vi ifcfg-<interface_name>

b. Edit the configuration parameters as given in the example here:

DEVICE="<interface_name>"

BOOTPROTO="static"

ONBOOT="yes"

IPADDR="<ip address of the network adapter>"

NETMASK="<

netmask of the cache network>"

NAME="<interface_name>"

c. Make a note of the address and netmask for later reference when configuring the cache network.

d. Save your changes to the configuration file.

e. Open the interface by running the command: ifup <interface name>

4. If port bonding is used, refer to Bonding Network Adapter Ports.

5. If a blade enclosure is used, disable FlexAddress in the blade enclosure.

6. Repeat this process for each network adapter in the cache network.

NOTE: Make sure that all RoCE network adapters used by the Fluid Cache network are dedicated to

the cache network and are not configured for any other network traffic.

Bonding Network Adapter Ports

Fluid Cache supports port bonding in active/passive mode (also called active/backup or master/slave).

Before implementing bonding on your network adapters, make sure that your cache network switches

and cabling are correctly configured for bonding. For an example of a system cabled for port bonding,

see Example Cabling Diagram.

NOTE: It is recommended that port bonding be used in configurations with redundant, uplinked

cache network switches.

The following example describes configuring port bonding on an RHEL system using Dell Networking

switches. For non-Dell Networking switches refer to the documentation specific to that networking

switch.

1. Configure a virtual interface to be used as a bonded port (in this example, bond0) by running the

following command:

vi /etc/modprobe.d/bond0.conf

2. In the configuration file, edit the parameters as follows:

alias netdev-bond0 bonding

3. Open the configuration file for the bonded port by running the following commands:

cd /etc/sysconfig/network-scripts

vi ifcfg-bond0

4. Edit the parameters in the configuration file as given in the example here:

DEVICE="bond0"

BOOTPROTO="static"
