L-SAS
Ports
(L-SAS0~L-SAS7),
The
motherboard
supports
eight
SAS
ports
on
two
onboard
connectors,
L-SAS0~L-SAS3
and
L-SAS4~L-SAS7.
Connect
hard
drives
to
these
SAS
ports
using
a
MiniSAS
to
4
breakout
cable,
one
for
each
connector
that
supports
up
to
four
drives
each.

NVM
Express
Connections
Two
NVM
Express
ports
are
located
on
the
serverboard.
These
ports
provide
high-speed,
low-latency
PCI-E
4.0
x8
connections
directly
from
the
CPU
to
NVMe
Solid
State
(SSD)
drives.
This
greatly
increases
SSD
data-throughput
performance
and
significantly
reduces
PCI-E
latency
by
simplifying
driver/software
requirements
resulted
from
direct
PCI-E
interface
from
the
CPU
to
the
NVMe
SSD
drives.
