Direct liquid cooling system
The HPE Apollo Direct Liquid Cooling System is a warm water, server-level cooling solution. This system removes heat from
high heat components like high wattage processors and DIMMs. The heat removal is done using a safe, environmentally
friendly server coolant. Liquid cooling is more efficient than traditional air cooling. Liquid cooling saves energy at the chassis

Definition
Each PCIe version corresponds to a specific data transfer rate
between the processor and peripheral devices. Generally, a
version update corresponds to an increase in transfer rate.

PCIe 4.x
The PCIe technology is under constant development. For the
latest information, see the PCI-SIG website.
PCIe devices communicate through a logical connection called an
interconnect or link. At the physical level, a link is composed of
one or more lanes. The number of lanes is written with an x prefix
with x16 being the largest size in common use.
