Differences between the 4-socket RH5885 V2 and 8-socket RH5885 V2

An 8-socket RH5885 V2 server is made up of two 4-socket RH5885 V2 servers connected through four QPI cables. One of the 4-socket RH5885 V2 servers serves as the master node and the other as the slave node.
Hardware differences:
? Rear I/O module: For the 4-socket server, the rear I/O module can be configured with two hard disks and the QPI cables cannot be connected. For the 8-socket server, the rear I/O module cannot be configured with two hard disks and the QPI cables are required.
? Hard disk quantity: 10 (4-socket server); 16 (8-socket server)
? CPU configuration: The 8-socket server must be configured with all CPUs and the 4-socket server can be configured with two or four CPUs.
? DIMM configuration: For the 4-socket server, DIMMs must be symmetrically installed on the memory risers. For the 8-socket server, apart from the symmetry requirements, the DIMMs must be installed on two nodes and the DIMM configuration must be the same on the two memory risers.
? RAID configuration: The 8-socket server requires only one RAID controller card, which must be installed on the master node.

Software differences:
? The slave node of the 8-socket server has no BIOS. Therefore, no BIOS information is displayed on iMana.
? The power button on the front panel of the slave node of the 8-socket server is available, but there is no related power control page on the iMana WebUI.
? The iMana of the slave node of the 8-socket server does not provide black box, power-on strategy, system start strategy, and serial port switchover functions.
