Description
The chassis features a redundant 2000W power supply consisting of two
hot-pluggable, Titanium-level power modules (96% efficiency). The
power redundancy allows the system to operate if one power supply
module fails or is replaced.
The chassis is designed to support twenty-four 2.5" hot-swappable hard
drive carriers. Twenty bays are SAS3 and, depending on the connections
to the backplane, four hybrid bays support NVMe or SAS3.
The system supports eleven PCIe
cards. These include seven cards with external ports and four internal
cards. Two can be double-width GPUs.
The front control panel, shown in
monitoring and power control. LEDs indicate system power, HDD
activity, and network activity, UID (unit identifier), overheat, and fan
failure. A main power button and a reset button are also included.
As shown in Figure 1-3, the rear panel includes the following I/O ports:
– One VGA (monitor) port
– One COM port
– One dedicated IPMI LAN port
– Two USB 3.0 ports
The chassis has an innovative cooling design that features four 8-cm fans
located in the middle section. Fan speed is determined by system
temperature as monitored by IPMI. Each power supply module also
includes a cooling fan.
The serverboard is fitted with an air shroud to maximize cooling.
