For three GPUs:
• If intrusion switch is installed, the server supports up to two GPU adapters in PCIe slot 2 and slot 3.
• PCIe slot priority to install the GPU: PCIe slot 1, PCIe slot 3, PCIe slot 2.
• High-performance fan must be selected.
• Internal drive assembly and rear drive cage are not supported.
• PCIe SSD adapter is not supported.
• It can only be supported when servers are configured as 4 x 3.5" SAS/SATA, 8 x 2.5" SAS/SATA (6 x 2.5"
SAS/SATA + 2 x HDD vacant), 6 x 2.5" SAS/SATA + 4 x 2.5" AnyBay (6 x 2.5" SAS/SATA + 4 x HDD
vacant) or 10 x 2.5" AnyBay (6 x 2.5" 4 x HDD vacant).
– For 8 x 2.5" SAS/SATA (6 x 2.5" SAS/SATA + 2 x HDD vacant), if HDDs are installed in slots 0-5, two 1 x
2.5" single filler should be installed on slots 6 and 7.
– For 6 x 2.5" SAS/SATA + 4 x 2.5" AnyBay (6 x 2.5" SAS/SATA + 4 x HDD vacant), if HDDs are installed
in slots 0-5, four 1 x 2.5" single filler should be installed on slots 6, 7, 8 and 9.
– For 10 x 2.5" AnyBay (6 x 2.5" 4 x HDD vacant), if HDDs are installed in slots 0-5, four 1 x 2.5"
single filler should be installed on slots 6, 7, 8 and 9.
