The counter-rotating fan configuration of the rack server supports N+1 redundant fans and is hot-swappable.
Which of the following statements about counter-rotating fans are correct? (Multiple choice)
- A . 5885H has 5 hot-swappable fans, which means there are 10 fans in series.
- B . Counter-rotating fans must ensure that the direction of rotation inside the fan is consistent.
- C . Counter-rotating fan is also called double counter-rotating fan
- D . The internal fan of a counter-rotating fan rotates in opposite directions
Intel’s QuickPath Interconnect technology is abbreviated as QPI. It is used to achieve direct interconnection between chips.
Which of the following statements about QPI is correct? (Multiple choice)
- A . Another highlight of QPI is that it supports multiple system bus connections, which Intel calls multi-FSB.
- B . A set of QPI has 10 data transmission lines, as well as the clock signals for the transmitter (TX) and receiver (RO)
- C . Total QPI bus bandwidth = number of transmissions per second (i.e. QPI frequency) x effective data per transmission (i.e. 16bit/8=2Byte) x bidirectional
- D . QPI is a serial high-speed point-to-point connection protocol based on packet transmission, which uses differential signals and a dedicated clock for transmission.
When the TaiShan server detects that the specified fan module model does not match or fails, an alarm of "large fan speed deviation" will be generated, affecting the heat dissipation of the server. The alarm level belongs to () alarm.
Huawei’s FusionDirector management software adopts a microservice-based Scale-out () architecture, which can be elastically expanded horizontally and has a multi-node multi-active architecture.
When using TaiShan server to build a real-time stream processing scenario big data solution, the data is generally stored in memory. Therefore, this architecture requires a large memory configuration.
- A . True
- B . False
Euleros can prevent failures in a timely manner, analyze and accurately locate failures, and automatically analyze the root causes of errors.
Which of the following belongs to hardware fault isolation? (Multiple choice)
- A . Support dynamic loading mechanism of diagnostic/response components
- B . Implement troubleshooting for hardware such as CPU and memory
- C . Support batch deployment and hot patch installation
- D . Implement CPU core and MEM isolation technology
In order to adapt to different application scenarios, the server has a variety of deployment architectures. The user interface is implemented through the www browser, a small part of the transaction logic is implemented on the front end (Browser), but the main transaction logic is implemented on the server side (Server), forming the so-called three-tier structure.
- A . B/S architecture
- B . C/S Architecture
- C . Internet Architecture
- D . Standalone system
You can use this command impcget -d powerstate to query the power-on and power-off status of Huawei rack servers.
- A . TRUE
- B . FALSE
Which of the following tuning strategies are suitable for Nginx physical servers as WebServers? (Multiple choice)
- A . Increase the buffer size to avoid a large number of new connections causing buffer overflow and the inability to establish connections.
- B . Reduce the number of TIME WAIT connections to avoid too many TIME WAIT connections occupying network resources and causing new connections
- C . Increase the range of available ports to avoid a large number of connections occupying ports and causing new connections to constantly search for available ports.
- D . Set the maximum number of open files to 1024 to limit Nginx resource overhead
According to the memory nameplate, drag the parameter name to the correct position.
