Mezzanine Side Board Options
The SC4-CONCERTO is equipped with a set of
high-speed local expansion interface
connectors, which can be optionally used to
attach either a low profile mezzanine module
(fits into the 4HP front panel envelope) or a side
board for an 8HP or even 12HP assembly in
total.
The connectors HSE1 and HSE2 are high speed
connectors, as required for PCI Express
®
Gen3
and SATA 6G. The socket EXP is used as a
legacy interface (e.g. HD Audio, LPC) and not
required for many mezzanine modules. All
connectors allow board-to-board heights of
9.5mm (C4* series), 10.0mm (S20, S40),
10.8mm (S60, S80), and 18.7mm (SC* side
cards 8HP assembly).
HSE1 can be configured for either 4 x PCIe
or
4
x SATA, or 2 x PCIe
and
2 x SATA, thanks to the
flexible HSIO channels of the CM238 PCH.
When HSE1 has been setup for SATA,
the
SC4-CONCERTO
can be combined e.g. with
low
cost SSD mass storage mezzanine modules such
as the C47-MSATA (dual mSATA carrier) or
C48-M2 (dual M.2 SATA sockets). For high
performance NVMe based SSD mezzanine
modules (S20/40/80), HSE1 must be configured
as PCIe x 4.
HSE2 is assigned to 4 x PCIe, and in addition
the 3
rd
DisplayPort video output. While S20 and
S60 get along with HSE1 only, the S40 and S80
mezzanine modules depend on both HSE1 and
HSE2, for additional I/O.
