Owners Manual

Checking the System Configuration

If any of the system checks below show that the firmware or drivers are earlier than the required versions,

update the components. See Requirements for Fluid Cache and Downloading Firmware, Drivers, and

Software.

Checking the Cache Device Firmware and Driver

NVMe Cache Devices

• Firmware— Refer to the Dell PowerEdge Express Flash NVMe PCIe SSD User’s Guide for instructions

on checking your current firmware version.

• Driver— Refer to the Dell PowerEdge Express Flash NVMe PCIe SSD User’s Guide for instructions on

checking your current driver version.

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

Checking the Network Adapter Firmware and Driver

To make sure that the correct firmware and drivers are installed on each of the Mellanox network

adapters used by Fluid Cache:

1. Get a list of interfaces on your server by running the command: ip addr

2. In the results, locate and write down the names of the network interfaces. These are often in the

format pXpY (for example, p6p2), but may be in the format ethX, emX, or other formats, depending

on your operating system.
