Legacy BIOS Boot Mode, they are not available at USB 3.0 speeds in the pre-boot environment.
Standard USB support (USB support from within the operating system) is provided by the OS
through the appropriate USB device drivers. Support for USB 3.0 varies by operating system.
For maximum compatibility of USB 3.0 devices with all operating systems, Hewlett Packard Enterprise
provides a configuration setting for USB 3.0 Mode. Auto is the default setting. This setting impacts USB
3.0 devices when connected to USB 3.0 ports in the following manner:
•
Auto (default)—If configured in Auto Mode, USB 3.0 capable devices operate at USB 2.0 speeds
in the pre-boot environment and during boot. When a USB 3.0 capable OS USB driver loads, USB
3.0 devices transition to USB 3.0 speeds. This mode provides compatibility with operating systems
that do not support USB 3.0 while still allowing USB 3.0 devices to operate at USB 3.0 speeds with
state-of-the art operating systems.
•
Enabled—If Enabled, USB 3.0 capable devices operate at USB 3.0 speeds at all times (including
the pre-boot environment) when in UEFI Boot Mode. This mode should not be used with operating
systems that do not support USB 3.0. If operating in Legacy Boot BIOS Mode, the USB 3.0 ports
cannot function in the pre-boot environment and are not bootable.
•
Disabled—If configured for Disabled, USB 3.0 capable devices function at USB 2.0 speeds at all
times.
The pre-OS behavior of the USB ports is configurable in System Utilities, so that the user can change
the default operation of the USB ports. For more information, see the UEFI System Utilities User Guide
for ProLiant Gen9 Servers on the Hewlett Packard Enterprise website
(http://www.hpe.com/info/ProLiantUEFI/docs).
External USB functionality
Hewlett Packard Enterprise provides external USB support to enable local connection of USB devices
for graphics server blade administration, configuration, and diagnostic procedures.
For additional security, external USB functionality can be disabled through USB options in UEFI System
Utilities.
Internal USB functionality
An internal USB connector is available for use with security key devices and USB drive keys. This
solution provides for use of a permanent USB key installed in the internal connector, avoiding physical
access to secure data.
HPE Smart Storage Administrator
The HPE SSA is a configuration and management tool for HPE Smart Array controllers. Starting with
ProLiant Gen8 servers, HPE SSA replaces ACU with an enhanced GUI and additional configuration
features.
The HPE SSA exists in three interface formats: the HPE SSA GUI, the HPE SSA CLI, and HPE SSA
Scripting. Although all formats provide support for configuration tasks, some of the advanced tasks are
available in only one format.
Some HPE SSA features include the following:
•
Supports online array capacity expansion, logical drive extension, assignment of online spares,
and RAID or stripe size migration
•
Provides diagnostic and SmartSSD Wear Gauge functionality on the Diagnostics tab
•
For supported controllers, provides access to additional features.
For more information about HPE SSA, see the Hewlett Packard Enterprise website
