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.

Differences between V2 and V3 servers
V3 servers differ from V2 servers in the following aspects: ? V3 servers use the latest Intel? Xeon? E5-2600 v3 series processors, with up to 18 cores per processor. ? V3 servers use the new-generation iBMC management system (with Huawei-developed management chips) for more secure and convenient management. In addition, V3 servers provide higher performance, PCIe expansion capabilities, and expanded memory size. For details, see the server user guide.

RH5885 V3 support for 32-bit OSs
The RH5885 V3 and RH5885H V3 support only 64-bit OSs.

Differences between the RH2288 V2 and RH2288 V3
The RH2288 V3/RH2288H V3 is different from the RH2288 V2 in the following aspects: ? Powerful performance: The RH2288 V3/RH2288H V3 uses the latest Intel? Xeon? E5-2600 v3 series processors, with up to 18 cores per processor. ? Easy management: The RH2288 V3/RH2288H V3 uses the new-generation iBMC management system for more secure and convenient management. ? Easy troubleshooting: The RH2288 V3/RH2288H V3 provides a fault diagnosis LED to display fault codes upon detecting faults. For other differences, see the server user guide.
