Server models installed with either one processor or two processors support Non-Volatile Memory Express (NVMe) SSDs. For the server model installed with one processor, one AnyBay backplane, and one PCIe switch, no more than four NVMe SSDs can be installed.
Rear hot-swap SAS/SATA drives are supported only when the processor TDP is lower than or equal to 105 watts.
A software RAID controller is integrated on the system board. The software RAID controller supports JBOD mode and RAID levels 0, 1, 5, and 10.
RAID 730-8i 1G Cache SAS/SATA adapter is not available for North America.
RAID 530-8i SAS/SATA adapter cannot be mixed with RAID 730-8i 1G Cache SAS/SATA adapter.
RAID 730-8i 2G Flash SAS/SATA adapter cannot be mixed with RAID 730-8i 1G Cache SAS/SATA adapter or RAID 930-8i SAS/SATA adapter.
The RAID 940 adapters can be mixed with the ThinkSystem 440-8i SAS/SATA PCIe Gen4 12Gb HBA and the ThinkSystem 440-16i SAS/SATA PCIe Gen4 12Gb HBA.
Mixing of RAID/HBA 430/530/730/930 adapters (Gen 3) and RAID/HBA 440/540/940 adapters (Gen 4) in the same system is not allowed.
RAID 930/940 series or 9350 series adapters require a RAID flash power module.
RAID 4350/5350/9350 series adapters cannot be mixed with HBA/RAID 430/440/530/540/730/930/940 series SAS/SATA adapters.
One processor: three hot-swap fans (including one redundant fan)
Two processors: four hot-swap fans (including one redundant fan)
For server models with twelve 3.5-inch drive bays and has one of following processors installed, if one fan fails, replace it with a new fan to avoid cooling problems: Intel Xeon 5122, 6140, 6140M, 6152, 8156, 8158, 8160, 8160M, 8164, 6242, 6240, 6248, 6252, or 6210U.
If your server comes with only one processor, three system fans (fan 1 to fan 3) are adequate to provide proper cooling. However, you must keep the location for fan 4 occupied by a fan filler to ensure proper airflow.
Power supplies (depending on the model)
One or two hot-swap power supplies for redundancy support
550-watt ac 80 PLUS Platinum
750-watt ac 80 PLUS Platinum
750-watt ac 80 PLUS Titanium
Sine-wave input (50 Hz to 60 Hz) required
Input voltage low range:
Minimum: 100 V ac
Maximum: 127 V ac
Input voltage high range:
Minimum: 200 V ac
Maximum: 240 V ac
For server models with 750-watt ac 80 PLUS Titanium power supplies, 100–127 V ac input voltage is not supported.
240 V dc input (input range: 180-300 V dc) is supported in Chinese Mainland ONLY.
Power supply with 240 V dc input cannot support hot plugging power cord function. Before removing the power supply with dc input, please turn off server or disconnect dc power sources at the breaker panel or by turning off the power source. Then, remove the power cord.
In order to for the ThinkSystem products to operate error free in both a DC or AC electrical environment, a TN-S earthing system which complies to 60364-1 IEC 2005 standard as to be present or installed.
Minimal configuration for debugging
One processor in processor socket 1
One memory DIMM at slot 3
One power supply
Three system fans (fan 1 to fan 3)
Acoustical noise emissions
Sound power level, idle
4.6 bels, minimum
4.8 bels, typical
5.9 bels, maximum
Sound power level, operating
4.7 bels, minimum
4.8 bels, typical
5.9 bels, maximum
These sound power levels are measured in controlled acoustical environments according to procedures specified by ISO 7779 and are reported in accordance with ISO 9296.
The declared acoustic noise levels are based on specified configurations and they may change depending on configurations/conditions.
The declared acoustic noise levels may increase greatly, if high-power components are installed, for example, some high-power NICs, CPUs, and GPUs.
The server is supported in the following environment:
This server is designed for standard data center environment and recommended to be placed in industrial data center.
