Non-NVMe Cache Devices

• Firmware— Make sure the firmware is up to date by using this command: dmesg | grep mtip32xx |

grep Firmware

For each cache device, you must get results similar to the following, showing firmware version B1490508

or later:

mtip32xx 0000:46:00.0: Firmware Ver.: B1490508

NOTE: The firmware version must be B1490508 or later. Otherwise, even though they are visible in

Enterprise Manager, the cache devices do not appear in the list of available devices when adding devices

to a Fluid Cache cluster.

• Driver— Make sure the driver is up to date and running by using this command: dmesg | grep -i

micron

For each cache device, you must get results similar to the following, showing driver version 2.4.2 or later:

Micron RealSSD PCIe Block Driver Version 2.4.2

CAUTION: If the cache devices contain data, back up this data before adding the cache devices to the

Fluid Cache cluster. All data on the cache devices are lost when they are added to the cluster.

NOTE: If your server already has cache devices installed, make sure that the cache devices you intend to

use in the Fluid Cache cluster are not used by any other application.

Preparing the Cache Network Adapters

1 Install the network adapters in PCIe slots on the servers (x16 slots, if available).

2 Check the network adapter driver and firmware versions, and the OFED package version, and then

update, if necessary.

NOTE: It is recommended to use an MTU of 1500 for RDMA or Cache Network adapter connectivity.

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.
