Single-Chassis Stateless Computing Feature White Paper 1 Feature Introduction

1 Feature Introduction

1.1 Background

1.2 Stateless Computing Feature Principles

1.3 Stateless Computing Hardware Requirements

1.1 Background

The E9000 adopts the Huawei stateless computing technology for data center O&M

operations, including server deployment, replacement, and migration, which facilitates O&M

and achieves device statelessness during maintenance. Stateless computing supports the

plug-and-play feature, which simplifies management and reduces O&M cost. For details

about the Huawei stateless computing technology, see the Huawei Server Stateless Computing

White Paper.

The E9000 single-chassis stateless computing feature is implemented by using the MM910

rather than external devices. The feature achieves stateless configuration for the basic

input/output system (BIOS) on each compute node, network, and universally unique identifier

(UUID). After configuration, compute nodes in the chassis can be deployed offline, the UUID,

media access control (MAC) address, and the worldwide name (WWN) remain unchanged

after replacement, and device replacement supports plug-and-play. No manual intervention is

required.

1.2 Stateless Computing Feature Principles

The E9000 chassis houses management modules (MMs), compute nodes, and switch modules.

The MMs monitor and manage the chassis and components and provide the web user

interface (WebUI), command line interface (CLI), and Simple Network Management Protocol

(SNMP) for management.

The E9000 single-chassis stateless computing feature uses MMs to configure and manage

compute nodes, which simplifies configuration and maintenance for the compute nodes.

Configuring the E9000 Single-Chassis Stateless Computing Feature

The stateless computing extracts compute node hardware configurations to form a

configuration policy file (profile). This separates hardware configurations from hardware and

Huawei E9000 Server




2

allows the profile to be configured offline, migrated, remotely deployed in batches, exported,

and imported.

The configurations of compute node hardware devices vary according to services and access

networks. For example, set the network interface card (NIC) mode to Single Root I/O

Virtualization (SR-IOV) for virtual machine (VM) services to improve virtualization

computing performance, and configure memory reliability for highly-reliable database

services.

As shown in Figure 1-1, the configuration of a compute node involves network configuration,

storage configuration, computing configuration, and management configuration.

Figure 1-1 Compute node configuration

Network configuration refers to the configuration for network access parameters,

including the MAC addresses, virtual NICs, VLANs and quality of service (QoS) for

virtual NICs, and remote Pre-boot Execution Environment (PXE) startup.

Storage configuration refers to the configuration for the storage network access,

including fiber channel (FC) or fiber channel over Ethernet (FCoE) WWN.

Computing configuration refers to the configuration for computing parameters, including

the operating system (OS) startup mode and sequence, memory reliability, availability,

serviceability (RAS), energy conservation, virtualization, and UUID.

Management configuration refers to the configuration for compute node management

parameters, including intelligent platform management interface (IPMI) behavior and the

system serial port.

The MAC address and WWN of a device are globally unique. Device replacement may cause

changes to the network, storage, or software configurations. Therefore, resource pools are

created for managing these parameters to ensure configuration inheritance. For example, a

MAC address resource pool provides the MAC addresses for the network ports on all compute nodes. If a device fails and is removed, its MAC address is reclaimed and will be

Huawei E9000 Server




3

assigned to the new device after replacement. This prevents network configuration changes

because of device replacement, simplifies maintenance, and reduces maintenance workload.

Automatic failover: When a resource pool is configured with active and standby nodes and an

active node fails, the active node is powered off automatically and a standby node takes its

place, with all configurations (including MAC addresses and WWPNs) migrated to the

standby nodes.

E9000 single-chassis stateless computing involves hardware configurations (such as BIOS,

NIC, and boot device settings). To realize seamless migration of service data from active

nodes to standby nodes, the service environment must be configured in a remote FC SAN.

Server uniqueness configuration is to set an UUID for a server.

Implementation Principles

The E9000 single-chassis stateless computing is controlled by the MM910 and the iMana

(iBMC), BIOS, and NIC on compute nodes. The compute node configurations (parameters)

are saved as a profile on the MM910. When a compute node is installed in the chassis, the

MM910 finds out its profile based on the mapping between profiles and slots, and then sends

the profile to the compute node. See Figure 1-2.

Huawei E9000 Server




15

Figure 1-2 Implementation principles

The compute node profile is stored on the MM910 and can be exported and imported. The

two MM910s in a chassis work in active/standby mode, and data can be synchronized

between them. The active/standby failover of the MM910 has no impact on the profile.

1.3 Stateless Computing Hardware Requirements

All the E9000 compute nodes and the MZ220, MZ510, MZ512, MZ910, and MZ912 NICs

support stateless computing. The MZ510 and MZ512 support the multi-channel function

while the MZ220, MZ910, and MZ912 do not support the function.

BIOS Configuration Support

The BIOS can support the stateless computing function only in legacy mode. If you select the UEFI

mode, the stateless computing function is unavailable.

WWNN is a MAC address with the prefix 1000 or 2000 respectively.

MAC address assignment policies are as follows:

Huawei E9000 Server




27

The MAC address segment 0x78D752CB0000 to 0x78D752CBFFFF is available, and

can be divided into multiple MAC address pools for profiles to choose.

Select one MAC address segment for each chassis to prevent MAC address conflicts.

Configuring or Modifying a MAC Address Pool

Step 1 On the Add MAC Address Pool page, set MAC Address Pool Name, Start MAC Address,

and Number of MAC addresses.

Step 2 Click OK.

The MAC address pool settings are displayed.

----End

If no slot is associated with a profile, the Slot Number drop-down list for this profile is blank.

----End

2.3 Configuring UUID Resource Pools

To use UUIDs, UUID resource pools must be configured first.

Huawei E9000 Server




28

Creating or Modifying a UUID Pool

Step 1 On the Add UUID Resource Pool dialog box, set UUID Resource Pool Name, UUID

Prefix, and Number of UUIDs.

Step 2 Click OK.

The UUID resource pool settings are displayed.

----End

Step 2 Click Query.

The queried information is displayed in the UUID list.

If no slot is associated with a profile, the Slot Number drop-down list for this profile is blank.

----End

2.4 Configuring Profiles

Before a compute node is installed, you can import the profile file or create a profile online.

Then the configurations will take effect immediately after the compute node is installed in the

chassis.

Profiles are classified into common and customized profiles. A common profile can be shared

by multiple compute nodes. After a common profile is configured with a MAC address pool

or UUID resource pool, the MAC addresses, WWPNs, and UUIDs are automatically assigned

to the compute nodes (in the node resource pool) associated with the common profile. If the

number of MAC addresses or UUIDs in the resource pool is insufficient for the compute

nodes, the resource pool cannot be associated with the common profile. A customized profile

can be used only by one compute node and contains a MAC address, WWNN, WWPN, and

UUID.

Do not manually configure the unique resources such as MAC addresses, WWNNs, and

WWPNs. The settings in the profile obtain resources from the resource pool. WWNs share a

resource pool with MAC addresses. A WWN is a MAC address with the prefix 1000 or 2000.

WWPN assignment policies are as follows:

A WWPN is a 64-bit string in the format of 1000+MAC address.

A WWPN ranges from 100078D752CB0000 to 100078D752CBFFFF.

Importing a Profile

Step 1 On the Profile Management page, click Import Profile.

The Import Profile dialog box is displayed.

Step 2 Select Import from board or Import from PC.

: export a profile to the local PC. It is recommended that the exported profile file

name, including the file name extension, contain 37 or fewer characters. This ensures

that the profile file can be successfully imported again.

: deliver the configuration profile file to a specified slot. The compute node in the slot

restarts automatically. The profile takes effect after the restart is complete.

After you restart, power on, power off, and gracefully restart a compute node, the profile is

automatically issued. No profile is delivered if you use the other restart methods.

----End

2.5 Configuring Binding

After manually creating or importing a profile file, you need to configure binding between the

profile file and slots. After a compute node is installed, the profile file is automatically issued.

The system generates an alarm if the profile file does not match the hardware of the inserted

compute node. For example, an NIC mismatches or the configured mezz module slot for a

NIC does not exist.

A common profile can be bound to multiple slots, and a customized profile can be bound to

only one slot.

Step 1 In the profile list, click a slot number in the Associated Slot column.

The Select Associated Slot dialog box is displayed.

If a profile is associated with no slot, the value of Associated Slot for this profile is None.

Step 2 Select the slot number to be associated with the profile, and click OK.

The selected slot number is displayed in the Associated Slot column.

Step 3 Click in the Operation column.

Step 4 Select a slot number and click Deliver to issue the profile to the compute node in the specified

slot.

----End

2.6 Migrating Profiles

The configurations can be migrated from one slot to another slot. After the migration, the

configurations are deleted from the source slot, and the configurations take effect in the

destination slot.

Step 1 On the Profile Management page, click Migrate Profile.

The Migrate Profile dialog box is displayed.

Step 2 Select the source slot from the Source slot drop-down list box, and select the destination slot

from the Destination slot drop-down list box.

Step 3 Click OK.

----End

2.7 Node Resource Management

You can configure compute node resource pools so that profiles and MAC addresses in the

profiles are automatically assigned to compute nodes in the compute node resource pools. The

assigned MAC addresses do not change due to insertion of more compute nodes. You can also

set active and standby nodes so that profiles of faulty active nodes automatically migrate to

standby nodes.

Huawei E9000 Server




34

Step 1 Node resource management

Choose Stateless Computing > Node Resource Management, and click Add Resource

Pool. The resource pool configuration dialog box is displayed.

Step 2 On the Add Resource Pool dialog box, set the resource pool name, associated profile (which

can only be a common profile), migration conditions, and active and standby nodes.

To edit migration conditions, click the edit icon.

35

For details about the migration conditions, see E9000 Server V100R001 Alarm Handling. By

default, all migration conditions are selected.

Selecting active and standby nodes

At least one active node must be selected. Do not select any standby nodes if active/standby

failover is not needed. By default, standby nodes do not have profiles and are powered off. If

a migration condition occurs for an active node, the active node is powered off and its profile

is migrated to a standby node. The standby node is then powered on.

Step 3 Migrate nodes after active/standby failures.
