Configure physical and logical drives (RAID arrays) for the server.

The supported RAID levels and RAID configuration methods vary by storage controller model. For more information, see the storage controller user guide for the server.

Installing the operating system and hardware drivers

Installing hardware drivers

IMPORTANT:

To avoid hardware unavailability caused by an update failure, always back up the drivers before you update them.

For newly installed hardware to operate correctly, the operating system must have the required hardware drivers.

To install a hardware driver, see the operating system installation guide for the server.

Replacing hardware options

If you are replacing multiple hardware options, read their replacement procedures and identify similar steps to streamline the entire replacement procedure.

Replacing a SAS/SATA drive

To configure RAID settings after the drive is replaced, see the storage controller user guide for the server.

Guidelines

The drives are hot swappable. If you hot swap an HDD repeatedly within 30 seconds, the system might fail to identify the drive.

If you are using the drives to create a RAID, follow these restrictions and guidelines:

· To avoid degraded RAID performance or RAID creation failures, make sure all drives in the RAID are the same type (HDDs or SSDs) and have the same connector type (SAS or SATA).

· For efficient use of storage, use drives that have the same capacity to build a RAID. If the drives have different capacities, the lowest capacity is used across all drives in the RAID.

· If one drive is used by several logical drives, RAID performance might be affected and maintenance complexities will increase.

· If the installed drive contains RAID information, you must clear the information before configuring RAID. As a best practice, install drives that do not contain RAID information.

Prerequisites

Take the following ESD prevention measures:

· Wear antistatic clothing.

· Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

· Do not wear any conductive objects, such as jewelry or watches.

To replace a drive that is installed with an operating system and is not configured with a RAID or is in a non-redundancy array, back up data, stop all services, and power off the blade server. For more information, see "Powering off the blade server."

When you replace a component, examine the slot and connector for damages. Make sure the pins are not damaged (bent for example) and do not contain any foreign objects.

Identify the position of the drive to be replaced.

Identify the RAID array information of the drive to be replaced. To replace a drive that is not configured with a RAID, back up all data if the old drive is full or the new drive is of a different model.

Removing a SAS/SATA drive

1. Remove the drive:

¡ To remove an SSD, press the button on the drive panel to release the locking lever, and then hold the locking lever and pull the drive out of the slot.

¡ To remove an HDD, press the button on the drive panel to release the locking lever. Pull the drive 3 cm (1.18 in) out of the slot. Wait for a minimum of 30 seconds for the drive to stop rotating, and then pull the drive out of the slot.

2. Remove the drive carrier. Remove the screws that secure the drive and then remove the drive from the carrier.

Installing a SAS/SATA drive

IMPORTANT:

¡ Access the CLI or GUI of the server.

· Observe the drive LEDs to verify that the drive is operating correctly. For more information about drive LEDs, see "Appendix A Server specifications."

Replacing an NVMe drive

To configure RAID settings after the drive is replaced, see the storage controller user guide for the server.

Guidelines

To hot swap NVMe drives, following these restrictions and guidelines:

· NVMe drives support hot insertion. Support for hot removal and managed hot removal of NVMe drives varies by operating system. To replace an NVMe drive in an operating system that does not support hot removal or managed hot removal of NVMe drives, first power off the server.

· To hot insert NVMe drives, insert the drives steadily without pauses to prevent the operating system from being stuck or restarted.

· Do not hot swap multiple NVMe drives at the same time. As a best practice, hot swap NVMe drives one after another at intervals longer than 30 seconds for the operating system to identify the installed or removed NVMe drive. If you insert multiple NVMe drives in a short period of time, the system might fail to identify the drives.

If you are using the drives to create a RAID, follow these restrictions and guidelines:

· For efficient use of storage, use drives that have the same capacity to build a RAID. If the drives have different capacities, the lowest capacity is used across all drives in the RAID. A drive with extra capacity cannot be used to build other RAID arrays.

· As a best practice, install drives that do not contain RAID information. If the installed drive contains RAID information, you must clear the information before configuring RAID. For more information, see the storage controller user guide for the server.

Prerequisites

Take the following ESD prevention measures:

· Wear antistatic clothing.

· Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

Replacing a mezzanine storage controller

For some storage controllers, you can order a power fail safeguard module to prevent data loss when power outage occurs.

A power fail safeguard module provides a flash card and a supercapacitor. When a system power failure occurs, this supercapacitor can provide power for a minimum of 20 seconds. During this interval, the storage controller transfers data from DDR memory to the flash card, where the data remains indefinitely or until the controller retrieves the data.

A supercapacitor has a lifespan of 3 to 5 years. If the lifespan of a supercapacitor expires, a supercapacitor exception might occur. The system notifies users of supercapacitor exceptions by using the following methods:

· For a PMC storage controller, the status of the flash card becomes Abnormal_status code. You can check the status code to identify the exception. For more information, see H3C Servers HDM Online Help.

· For an LSI storage controller, the status of the flash card of the power fail safeguard module becomes Abnormal.

You can also review log messages from HDM to identify supercapacitor exceptions.

For the power fail safeguard module to take effect, replace the supercapacitor before its lifespan expires.

The supercapacitor might have a low charge after the power fail safeguard module is installed or after the server is powered up. If the system displays that the supercapacitor has low charge, no action is required. The system will charge the supercapacitor automatically. You can view the status of the supercapacitor from HDM or OM.

IMPORTANT:

After the supercapacitor replacement, verify that cache related settings are enabled for logical drives. For more information, see H3C Servers HDM Online Help.

Use Table 4 to identify the compatible power fail safeguard module or supercapacitor of a storage controller. For more information about storage controller connectors on the system board, see "Appendix A Server specifications."

Replacing a DIMM

WARNING!

To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before touching them.

About DIMMs

The server supports DDR4 and DCPMM DIMMs. Compared with DDR4 DIMMs, DCPMM DIMMs provide larger capacity and can protect data from getting lost in case of unexpected system power outage.

DDR4 DIMMs include LRDIMM and RDIMM.

· RDIMMs can perform parity check on addresses.

· Compared with RDIMMs, LRDIMMs provide larger capacity and higher bandwidth.

Both DDR4 and DCPMM are referred to as DIMMs in this document, unless otherwise stated.

Guidelines

The server provides six DIMM channels per processor and each channel has two DIMM slots. If the server has one processor, the total number of DIMM slots is 12. If the server has two processors, the total number of DIMM slots is 24. The support for DIMMs varies by CPU brand.

You can install only DDR4 DIMMs on the server or install both DCPMM and DDR4 DIMMs on the server.

DIMMs are not hot swappable.

DIMM and processor compatibility

Processors of Intel SkyLake and Jintide C series (C1 and C2) support only DDR4 DIMMs, and the Intel Cascade Lake processors support configuring only DDR4 DIMMs or a mixture of DCPMM and DDR4 DIMMs.

When you install a DIMM, use Table 7 to verify that it is compatible with the processors.

Table 7 DIMM and processor compatibility

Processor	Memory type @ frequency	Remarks
· Intel SkyLake · Jintide C1	· DDR4 @ 2933 MHz · DDR4 @ 2666 MHz	Compatible with the following DDR4 DIMMs with a frequency of 2933MHz: 0231ABE2, 0231AC4S, 0231AC4R, 0231ABDT, 0231AC4V, 0231AC4Q, 0231ABDU, 0231AC4T, 0231AC4U.
Intel Cascade Lake	· DDR4 @2933 MHz · DCPMM @2666 MHz	Processors of the following models are not compatible with DCPMM DIMMs: · 32XX series. · 42XX series (4215 and 4215R excluded).
Jintide C2	DDR4 @2933 MHz	N/A

DIMM frequency

NOTE:

To obtain the frequency of a DIMM and the maximum DIMM frequency supported by a processor, contact Technical Support.

The actual operating frequency of DIMMs also depends on the maximum DIMM frequency supported by the processor and the number of DIMMs per channel.

· If the supported frequency is lower than the DIMM frequency, the DIMMs operate at the supported frequency.

· If the supported frequency is higher than the DIMM frequency, the DIMMs operate at the DIMM frequency.

· If a supported frequency is equal to the DIMM frequency, the actual operating frequency depends on the number of DIMMs per channel.

¡ When the supported frequency and the DIMM frequency are both 2933 MHz:

- If one DIMM is installed per channel, the DIMM operating frequency is 2933 MHz.

- If two DIMMs (including a mixture of DCPMM and DDR4 DIMMs) are installed per channel, the DIMM operating frequency is 2666 MHz.

¡ When the supported frequency and the DIMM frequency are lower than 2933 MHz, the DIMMs operate at the DIMM frequency regardless of the number of DIMMs per channel.

Use Figure 4 to identify the DIMM operating frequency on the server.

Figure 4 Identifying the DIMM operating frequency

For example, for DIMMs to operate at 2933 MHz, make sure the following conditions are met:

· The server uses a Cascade Lake CPU that supports a maximum of 2933 MHz DIMM frequency.

· DIMMs with a maximum of 2933 MHz data rate are used.

· Only one DIMM per channel is installed, and the DIMMs must be inserted in the white DIMM slots.

Guidelines for installing only DDR4 DIMMs

When you install only DDR4 DIMMs, follow these restrictions and guidelines:

· Make sure their corresponding processors are present before powering on the server.

· Make sure all DDR4 DIMMs installed on the server have the same product code. For information about DIMM product codes, contact Technical Support.

· Each channel supports a maximum of 8 ranks. For information about ranks, see "Appendix B Component specifications."

· For general DIMM populations, see Figure 5 and Figure 6.

· For the configured memory mode to take effect, make sure the following installation requirements are met:

Memory mode	DIMM population requirements
Independent	· If one processor is present, see Figure 5. · If two processors are present, see Figure 6.
Mirror	· A minimum of two DIMMs for a processor. · This mode does not support DIMM population schemes that are not recommended. ¡ If one processor is present, see Figure 5. ¡ If two processors are present, see Figure 6.
Memory Rank Sparing	· Make sure no less than two ranks are configured for each channel. · Strictly follow the DIMM population schemes: ¡ If one processor is present, see Figure 5. ¡ If two processors are present, see Figure 6.

NOTE:

· If the DIMM configuration does not meet the requirements for the configured memory mode, the system uses the default memory mode (Independent mode). The BIOS does not display the configuration item for Independent mode.

· In Figure 5 and Figure 6, the black DIMM slots (for example, the A12 slot) are grey colored, and the white DIMM slots (for example, the A6 slot) are not colored.

Figure 5 DDR4-only DIMM population schemes for one processor

Figure 6 DDR4-only DIMM population schemes for two processors

Guidelines for installing a mixture of DCPMM and DDR4 DIMMs

When you install DCPMM and DDR4 DIMMs on the server, follow these restrictions and guidelines:

· DCPMM DIMMs do not support ADR.

· Make sure their corresponding processors are present before powering on the server.

· Make sure the total size of DIMMs installed for each processor does not exceed the maximum capacity supported by the processor.

· The 32xx series and 42xx series processors do not support DCPMM DIMMs.

· Make sure all DDR4 DIMMs have the same product code and all DCPMM DIMMs have the same product code. For information about DIMM product codes, contact Technical Support.

· Depending on the processor and DIMM configuration, use the schemes shown in Figure 7, Figure 8, and Figure 9 to populate the DIMM slots.
