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

1 Feature Introduction
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

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.

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.

1 Feature Introduction
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.

----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.

: 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.

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.

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.
