General memory module installation guidelines
To ensure optimal performance of your system, follow the general guidelines when configuring your system memory. If your
system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during memory
configuration, or operate with reduced memory.
NOTE:
Memory configurations that fail to observe these guidelines can prevent your appliance from booting, stop
responding during memory configuration, or operating with reduced memory.
The following are the recommended guidelines for installing memory modules:
● DIMM, 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 VxRail, sockets A1 to A12 are available.
For dual-processor VxRail, 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 two 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.
● It is recommended that you populate:
○ 4, 6, 8, and 12 memory modules for single-processor configurations, and
○ 8, 12, 16, and 24 memory modules (4, 6, 8, and 12 memory modules per processor) for dual-processor configurations.
One memory module per channel maximizes the performance.
Expansion cards and expansion card riser
An expansion card in the VxRail 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 VxRail 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 VxRail 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 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:
