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.

Whether an RH5885 V2 8-socket server can be divided into two 4-socket servers
In principle, an RH5885 V2 8-socket server is not allowed to be divided into two 4-socket servers unless the customer requests it. If it is divided and a CPU error occurs on one server, the CPU error will also be reported on the other server. In this case, you need to use the BMC for 4-socket servers instead.

Whether the USG6650 hard disk has a hard disk card
The USG6650 supports two types of hard disks, namely, SM-HDD-SAS300G-A and SM-HDD-SAS300G-B. Model A uses the tray of the device, and model B has its own tray.
