USB support 
Hitachi Vantara G2 servers support all USB operating speeds depending on the device that 
is connected to the server. 
External USB functionality
 
Hitachi Vantara provides external USB support to enable local connection of USB devices for server 
administration, configuration, and diagnostic procedures. 
For additional security, external USB functionality can be disabled through USB options in UEFI System 
Utilities.
 
Redundant ROM support 
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The 
server has a single ROM that acts as two separate ROM images. In the standard implementation, one 
side of the ROM contains the current ROM program version, while the other side of the ROM contains a 
backup version. 
NOTE: The server ships with the same version programmed on each side of the ROM. 
Safety and security benefits 
When you flash the system ROM, the flashing mechanism writes over the backup ROM and saves the 
current ROM as a backup, enabling you to switch easily to the alternate ROM version if the new ROM 
becomes corrupted for any reason. This feature protects the existing ROM version, even if you 
experience a power failure while flashing the ROM.
