Mainboar As the most important server component, the mainboard
d integrates basic components, such as the BIOS chipset,
Platform Controller Hub (PCH) chipset, and PCIe expansion
slots, and provides CPU sockets, DIMM slots, and slots for
installing other components.
Integrates an SM750 graphics card, providing a memory
capacity of 32 MB and supporting a maximum resolution of
1920 x 1200 at 60 Hz with 16 M colors.
NOTE
● After a dedicated graphics card driver is installed, only Windows
Server 2012, Windows Server 2012 R2, Windows Server 2016 can
support the resolution of 1920 x 1200 while other OSs only
support the maximum resolution supported by the built-in drivers.
● If the resolution is greater than 1024 x 768, the display effect may
be affected.
SATADO The SATA disk on module (SATADOM) is a SATA SSD or SATA
M DOM electrical drive. It is a quick memory storage media unit
that features high energy efficiency and stability.
SATADOMs use flash memory to store data. NAND flash
memory is now commonly used in the industry. It uses
electrons on the floating gate to store data. However,
electrons frequently passing through the floating gate can
weaken the gate's ability to store electrons and eventually
make the gate unable to store electrons. This problem is
common to NAND flash memory. To prevent failures of
NAND flash memory, accurately assess the amount of service
data to be written.
NOTE
● If the SoftRAID function is enabled on the server, the STATADOM
supports SoftRAID, which supports RAID 0 and RAID 1.
● A SATADOM can be used only as a boot drive for Linux OSs.
● SATADOMs have weak endurance and cannot be used as data
storage devices. Use enterprise-level HDDs or SSDs to replace
SATADOMs for data storage when frequent data erasure
operations are involved.
● Installing write-intensive service software on SATADOMs will
accelerate the write life consumption and result in perpetual
damage of SATADOMs. SATADOMs cannot be used for such
services.
● SATADOMs cannot be used in cache scenarios.
● SATADOMs and built-in driver SATA ports are exchangeable.
● The RH2288H V3 supports two SATADOMs. The mappings
between the physical positions and the port numbers in the BIOS
are as follows: SATA1 – PORT4; SATA2 – PORT5.
