2.2.2 System Architecture
SL series server products include 1U models (SL101-D04R, SL101-D10R), 2U models
(SL201-D08R, SL201-D12RE, SL201-D12R, SL201-D25RE, SL201-D08R-NV, SL201-D12R-NV)
4U models (SL401-D24RE, SL401-D36RE) bays, motherboard name: G4DCL-B, the models are
the same except for the hard disk connection method and the maximum number of compatible hard
disks.
The main board features are as follows:
The CPU adopts the third -generation Intel
®
ICE-Lake
®
scalable processor, LGA 4189
socket, TDP 270 W; single processor can reach up to 40 cores, providing excellent system
performance, the highest frequency is 3.2GHz, using Intel the largest single core that can
be achieved by the Turbo acceleration technology, the maximum overclocking (Max Turbo
Frequency) is 3.4GHz;
Supports Intel Hyper-Threading Technology, allowing multiple threads to run concurrently
on each processor core (up to 2 threads per core) to improve multi-threaded application
performance;
Each CPU supports 8 DDR4 channels , each channel supports 2 memory sticks,
RDIMM/LRDIMM;
Supports up to 32* 2400/2666/2933/3200 MHz DDR4 LRDIMM/RDIMM/ECC
memory, and supports a single capacity of 8GB, 16GB, 32GB, 64GB, 128GB, 256GB.
Supports Intel's second-generation Optane memory BPS (maximum 512GB per
DIMM);
There are 3 PCIE RISER slots on the board, among which: RISER1: 32 PCIE LANEs
all come from CPU0, RISER2: 32 PCIE LANEs all come from CPU1, RISER3: 16
PCIE LANEs come from CPU1;
Motherboard integrated AST2500 BMC chip, standard KVM function
G4DCL-B motherboard provides 2* M.2 Key M SSD slots, supports 2280 size, only
supports PCIe 4.0 X 4 signals;
2 Gigabit Ethernet ports are integrated on the motherboard, using 88E1512 chip from PCH;
South bridge PCH adopts INTEL LEWISBURG C620A series chipset;
Modular design of hard disk module, PCIE expansion module, power supply, fan and other
components, tool-free maintenance
PCH leads out 14 SATA Ports, maximum speed: 6Gb/s, compatible with SATA 1.5Gb/s,
3.0Gb/s; SATA Controller outputs 8 SATA PORTs, while SSATA outputs 6 SATA
PORTs, of which SATA PORT has 8 PORTs, according to Sequentially introduced into
2 SFF - 8643 connectors, while the first 4 PORTs of SSATA are introduced into a SFF -
8643 connector, and the latter 2 PORTs are introduced into 7PIN SATA connectors for
connecting SATA DOM and DVD;
The BMC chip in this single board adopts the AST2500 control chip of ASPEED
Company, which is used for IPMI remote management. VGA output port, dedicated
Gigabit RJ45 management network port, and connected to PCH via RMII/NCSI.
The system architecture motherboard block diagram is as follows:
