The following are the recommended guidelines for installing memory modules:

● RDIMMs and LRDIMMs must not be mixed.

● Up to two RDIMMs can be populated per channel.

● Up to two LRDIMMs can be populated per channel.

● If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory

module(s) or slower depending on appliance DIMM configuration.

● Populate memory module sockets only if a processor is installed. For single-processor appliance, sockets A1 to A12 are

available. For dual-processor appliance, sockets A1 to A12 and sockets B1 to B12 are available.

● Populate all the sockets with white release tabs first, and then followed by the black release tabs.

● Mixing of more than one memory module capacities in an appliance is not supported.

● In a dual-processor configuration, the memory configuration for each processor should be identical. For example, if you

populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.

● VxRail appliances require that you populate six memory modules per processor for single processor configurations and twelve

memory modules per processor for dual-processor configurations. One memory module per channel at a time to maximize

performance.

Expansion cards and expansion card riser

An expansion card in the appliance is an add-on card that can be inserted into an expansion slot on the system board or riser

card to add enhanced functionality to the appliance through the expansion bus.

NOTE:

To avoid data loss, ensure that you refer to the procedures in the SolVe Desktop application before performing any

memory or expansion card replacement or upgrade procedures.

NOTE:

A System Event Log (SEL) event is logged if an expansion card riser is unsupported or missing. It does not prevent

your appliance from turning on and no BIOS POST message or F1/F2 pause is displayed.

Expansion card installation guidelines

The VxRail P570, P570F, V570, V570F, and S570 appliance support PCI express (PCIe) generation 3 expansion cards, that

can be installed on the system board using expansion card risers. The following table provides detailed information about the

expansion card riser specifications:
