■
MNT Port/RMT Port/FST Port
The MNT port is used for operation management, the RMT port is used for the remote support function, and
the FST port is used for maintenance.
The specifications for the MNT port, the RMT port, and the FST port are provided below.

PCIe Flash Modules (PFM)

The read cache capacity significantly increases when Extreme Cache is used. PCIe Flash Modules (PFM) are
installed to operate Extreme Cache.
1.4TB (700GB PFM ´ 2) and 2.8TB (1.4TB PFM ´ 2) PFM capacity options are available for Extreme Cache.
Two PFMs are installed in each controller. The maximum capacity for each controller is 2.8TB.
PFMs can be added during system operation. When an error occurs, a replacement can be made while the
system is running.
6.1.3

Batteries

Three batteries are installed in the controller enclosure as backup power supply sources.
If one of the three batteries fails, the failed battery can be replaced while the system is running.
The batteries are charged from an external power source while the ETERNUS DX is running normally. If a
power failure is detected, the data in the cache memory is saved to the BUD in the controller by using battery
power. There is no limit to the post-failure data retention time.
6.1.4

Power Supply Units

The power supply unit transforms input AC power from a power socket to DC power and supplies power to
each component. A controller enclosure has two power supply units. Each power supply unit contains fans.
If one of the power supply units fails, the failed unit can be replaced while the system is running.
