Installation Limitations for Windows Environment
For Windows environment, PCI cards have additional installation limitations as for the number of the cards to be
installed, depending on the combination of the PCI cards. Please refer below for the details.
In case of using CPU SKU with small number of thread and require large I/O space, Hyper Threading is recommended
to
“ON” (default setting) in order to avoid performance decrease due to lack of I/O space.
Windows Hyper-Threading = ON
