2.1 Architecture Design

The X6800 uses the new-generation Huawei-proprietary system architecture. The architecture design has the following features: l The 4 U chassis can hold different models of server nodes.

l All server nodes in an X6800 share the PSUs in 1 + 1 or 2 + 2 redundancy.

l All fan modules in an X6800 share the fan modules in N + 1 redundancy.

l The X6800 supports network controller sideband interface (NC-SI) and provides service and management ports from the front and service ports from the rear of the server.

2 System Design

2.2 Heat Dissipation

l The system draws in air from the front of the chassis, delivers the cool air to the server nodes, hard disks, processors, dual in-line memory modules (DIMMs), backplane, and fan modules, and then discharges warm air through the rear of the chassis.

l Two PSUs are installed in each side of the server chassis. Separated ventilation channels are reserved to deliver the return air from the PSU fans for cooling.

l The system fans implement cooling of the management boards and I/O boards on the fan modules.

l The high-pressure counter-rotating fans offer 10% higher air volume than common fans.

The refined air channels implement concentrated cooling of heat-sensitive devices. The optimal distribution of temperature sensors covers all areas of high heat concentration

(server hotspots), facilitating accurate fan speed adjustment. The cellular design on the panel offers a porosity of 66%, which is 10% higher than that of square holes. The fans use the PID algorithm to adjust the fan speed smoothly and efficiently. All these heat dissipation designs ensure long-term stable running of the server at 40ºC.

Figure 2-2

shows the X6800 ventilation channels.

Figure 2-2 Ventilation channels

2.3 Management and Monitoring

l

The iBMC and HMM implement management and monitoring of the X6800. The iBMC on each node implements node management through the Intelligent Platform

Management Interface (IPMI), KVM, or virtual DVD-ROM drive. The HMM implements chassis management, which includes fan management, PSU management, and chassis asset management.

l The HMM and iBMC implement aggregation management through LAN switches

(LSWs). The LSWs provide external GE port, through which users can access the HMM and iBMC to manage the chassis and server nodes.



7

HUAWEI X6800 Server

White Paper

2 System Design l

The HMM works with the fan switch boards to implements fan management. The fan switch board provides five independent pulse-width modulation (PWM) control signals to control the fan speed and ten tachometer (TACH) signals to detect the fan speed.

Based on the ambient temperature and temperature of the temperature-sensitive components on the boards, the HMM uses Huawei speed adjustment algorithms to determine a proper rotation speed, and then sends it to the fan switch board. The fan switch board receives fan speed signals from the fan modules and reports the fan module status to the HMM.

l PSU monitoring and management: The HMM provides one inter-integrated circuit (I

2

C) for managing the PSUs and general purpose input/output (GPIO) pins for detecting the

PSU installation status and PwrOk state. The HMM supports queries on PSU output power, PSU installation status, and PSU alarms.

Figure 2-3

shows the X6800 management and monitoring design.

Figure 2-3 X6800 monitoring and management design

2.4 Advantages

l The X6800 uses Huawei proprietary system architecture with front maintenance and front and rear access cabling, providing easy maintenance of the cool wind area.

l The X6800 provides eight slots for installing 4U4 and 4U8 server nodes. This unified architecture allows flexible configuration of computing and storage resources and easy upgrades and maintenance.

l The X6800 uses a modular design and supports hot-swappable server nodes, hard disks,

PSUs, fan module, and I/O module, which increases maintenance efficiency.

l The X6800 uses the iBMC and HMM to implement management. The iBMC manages server nodes, and the MMC manages the fan modules, PSUs, and chassis.

l All server nodes share the PSUs and heat dissipation, improving PSU conversion efficiency and reducing system power consumption.

4 Security Management

4.1 Compute Node

Compute nodes support security solutions based on the Trusted Platform Module (TPM).

The TPM is a security chip that complies with the Trusted Computing Group (TCG) TPM specification. The hardware-based TPM provides data encryption, password protection, authentication, and internal resource protection. The TPM V1.2 is available.

The TPM is installed on a compute node and connects to the compute node through a port.

You can access a compute node with the TPM only after authorization, which ensures data security based on hardware.

4.2 MM

The MM security involves hierarchical command protection, remote Secure Shell (SSH) login, and Simple Network Management Protocol (SNMP) encrypted authentication.

Hierarchical Command Protection

To ensure operation security, only the user who has passed the authentication can access the

MM through an Ethernet port.

The MM provides hierarchical protection for command lines. The commands are classified into commands of the monitoring level, configuration level, and management level in ascending order. Login users are classified into common user, operator, and administrator.

After logging in to the MM, a user can run only the commands corresponding to or lower than the specified level.

Remote SSH Login

The MMs support Secure Shell (SSH), which provides security protection and verification functions. SSH defends against various attacks on an insecure network. The MMs also support Secure File Transfer Protocol (SFTP) to provide encryption protection for file transfer.

SNMP Encrypted Authentication

The MMs support the SNMPv3 and SNMP Trap v3 encrypted authentication functions. If the

MMs are managed by the network management site using SNMP, the user-based security mode (USM) encryption authentication is used to ensure security of the MMs.

The MMs support MD5 or SHA SNMP V3 and SNMP Trap V3 authentication, and DES or

AES encryption. The default authentication type is MD5, which is easy to crack. You are advised to set the authentication type to SHA.

NOTE

The MMs support SNMPv1, SNMPv2c, FTP, and Telnet protocol, which are disabled by default for security purposes. If you need to enable SNMPv1 or SNMPv2c, contact Huawei technical support.

Intelligent power management

Out-of-band aggregation management

Specifications

Uses the power capping technology to increase deployment density and dynamic energy saving technology to lower operating costs.

Integrates the out-of-band management of all server nodes in the chassis, reduces the cabling of the management network, and shortens maintenance time.

5.3 Management Principles

Management principles of the X6800 are as follows: l The Integrated Baseboard Management Controller (iBMC) and the Hyper Management

Module (HMM) implement management and monitoring of the X6800. The iBMC on each node implements node management through the Intelligent Platform Management

Interface (IPMI), KVM, or virtual DVD-ROM drive. The HMM implements chassis management, which includes management of fan modules, PSUs, and chassis assets.

l The HMM and iBMC implement converged management over the LAN switch (LSM) chip in the chassis. The LSM provides an external GE port. You can log in to the HMM and iBMC over the external GE port to manage the chassis and server nodes.

l The HMM works with the fan switch boards to implements fan management. The fan switch board provides five independent pulse-width modulation (PWM) control signals to control the fan speed and ten tachometer (TACH) signals to detect the fan speed.

Based on the ambient temperature and temperature of the temperature-sensitive components on server blades, HMM uses Huawei speed adjustment algorithms to determine a proper rotation speed, and then sends it to the fan switch board. The fan switch board receives fan speed signals from the fan modules and reports the fan module status to the HMM.

l PSU monitoring and management: The HMM provides one inter-integrated circuit (I

2

C) for managing the PSUs and general purpose input/output (GPIO) pins for detecting the

PSU installation status and PwrOk state. The HMM supports queries on PSU output power, PSU installation status, and PSU alarms.

The following shows the X6800 management plane.

5.4 Management Modes

Access Modes

The X6800 server nodes and Hyper Management Module (HMM) are configured with independent IP addresses. You can access the Intelligent Baseboard Management Controller

(iBMC) of a server node or the HMM to manage the X6800.

l On a server node, you can:

–

Directly access the iBMC through the iBMC management network port on the server node.

–

Access the iBMC through a service network port on a network interface card (NIC) over a network controller sideband interface (NC-SI).

– Access the HMM in transparent transmission mode through the iBMC management network port. For details, see Configuring Transparent Transmission.

l Through the converged management network port on the chassis mounting ear or on the

HMM, you can:

– Directly access the HMM.

–

Access the iBMC in converged management node. For details, see Configuring

Network Port Aggregation.

Networking

The X6800 provides flexible networking of the management network: l Point-to-point networking

The server nodes are directly connected to the switch outside the X6800 chassis to form an out-of-band management network plane. You must set LAN Port Configuration to Dedicated on the BIOS.You also can connect Data plane network and transfer management message through NC-SI.

Figure 1

shows the cable connections.

5 Management l Cabling from the mounting ear for converged management

The X6800 is connected to the switch outside the X6800 chassis through a cable led out from the front mounting ear on the X6800 chassis. The out-of-band management network communicates with the X6800 server nodes through the LAN switch (LSW) chip in the

X6800 chassis. You need to change LAN Port Configuration (Dedicated by default) to Shared

on the BIOS.

Figure 2


Figure 5-3 Cabling from the mounting ear (converged management)

Issue 03 (2017-04-27) l Cabling from the HMM for converged management

The X6800 is connected to the switch outside the X6800 chassis through a cable led out from the converged management port on the HMM in the X6800 chassis. The out-of-band management network communicates with the X6800 server nodes through the LSW chip in the X6800 chassis. You need to change LAN Port Configuration (Dedicated by default) to

Shared on the BIOS.

5 Management

NOTICE

l The active/standby switchover feature of the X6800 HMMs is not available at present.

Therefore, the X6800 comes with only one HMM.

l The converged management network port on the HMM provides an external interface for the LSW. The HMM is different from the management module (MM) of blade servers.

The MM integrates a management plane switching chip, while the HMM only provides an external port for the management plane switch.

l Enhancement has been made on the management network ports on the mounting ear and on the HMM to prevent self-loop between the LSW and management switches in the equipment room. If both of the ports are connected to the management network, the port on the mounting ear has higher priority and the port on the HMM will be disabled by software.
