Overview of the FX700 Main Unit
This section provides an overview of the FX700 main unit.
The FX700 main unit is a product that accommodates multiple blades having ARM-based CPUs (A64FX).
This product also includes a BMC board provided with BMC/CPU firmware.
Remarks
Use the same type of blade when mounting multiple blades. Operation with a mix of blades of different
types cannot be guaranteed.
It has the following features.
-
Each blade has two nodes/two CPUs mounted. The FX700 main unit (2U chassis) accommodates one
to four blades.
-
The CPU uses the A64FX processor developed by Fujitsu for HPC. Armv8.2-A SVE is the command
set architecture used by this CPU, which has 48 cores and maintains performance at 3.072 TFlops
(operating at 2.0 GHz). An HBM interface and PCI-Express (PCIe) Gen3 16-lane controller are built in.
-
The CPU processor supports two frequencies: 1.8 GHz and 2.0 GHz.
-
The main memory is High Bandwidth Memory (HBM), providing a high memory bandwidth of 1,024
GB/s.
-
Each node is equipped with the following I/O hardware:
HHHL PCIe card slot x 1
2280 M2 slot x 1
1 GbE LAN port x 1
-
Using eight nodes as a single control unit, the BMC processor in the chassis monitors and controls the
hardware inside the FX700 main unit.
-
The firmware installed in the chassis performs hardware diagnostics at node power-on.
-
The supported OS is Red Hat Enterprise Linux 8.
