() is used to describe the average continuous failure-free time of a product during operation or testing.
An engineer is participating in the development and testing of a storage product system. When performing the compilation optimization phase of the IOPS performance optimization part, which of the following operations will he not perform?
- A . Improve icache hit rate based on FGO
- B . Manual prefetching improves dcache hit rate in loop
- C . Improve the spatial locality of instructions between functions and improve the icache hit rate by rearranging the function positions during the compilation and linking phase
- D . Improving instruction prefetch hit rate based on hot and cold partitions
A financial customer purchased a Huawei OceanStor Pacific series distributed storage for business deployment. In order to ensure the reliability of business data, engineers configured the HyperSnap feature on the storage system. This feature is based on () snapshot technology. When the system receives a data write request and needs to modify the source volume, the storage system will allocate new storage space for the newly written data in the storage pool and modify the mapping relationship between data and storage space in the source volume.
Generally speaking, storage system failures can be divided into two categories: storage side failures and external environment failures, depending on the components where the failure occurs. Which of the following items belong to external environment failures? (Multiple choice)
- A . Interface module failure
- B . HBA card failure
- C . Link disconnection
- D . Fan failure
In Huawei OceanStor 6810 converged storage system, the global cache feature refers to the use of slicing + DHT algorithm to evenly distribute each LUN to all controllers for serial processing. Write requests are written to the global cache, and read requests are pre-fetched and hit in the global cache.
- A . True
- B . False
Huawei’s all-flash storage’s fully balanced (Active-Active) architecture ensures a securities company’s high-concurrency trading business. Which of the following statements about this architecture are correct? (Multiple choice)
- A . Evenly distribute IO to all front-end ports to achieve access load balancing
- B . All controllers participate in business processing, LUN has no ownership, and controller load balancing is achieved
- C . IO is evenly distributed to all controllers, achieving front-end load balancing
- D . Data is evenly distributed to all SSDs, achieving disk load balancing
A financial customer purchased several Huawei flash storages and deployed active-active services. During an operation and maintenance process, the engineer found that the health status of the active-active tenant pair was "failed", which means that the "operation status" of the active-active tenant pair was "failed" or "unsynchronized".
- A . True
- B . False
A bank customer purchased several Huawei flash storages to carry upper-level Oracie business data. Now the Oracle database suddenly fails. Engineers need to collect Oracle’s alert log files to locate the fault.
Which of the following commands can engineers not use to query the alert log path? (Multiple choice)
- A . CRS HOME/bin/diagcollection,sh
- B . show parameter Background dump dest
- C . db2support Outpath -d db name -c
- D . ioscan -funC Disk>/home/pvlinks disk
Huawei’s flash storage system can cope with the challenges brought by flexible business changes by means of architecture expansion. Which of the following descriptions of the storage system expansion architecture is wrong?
- A . The upgrade of the Scale-Out horizontal expansion architecture is based on the node.
- B . Scale-Up is a traditional vertical expansion architecture, which uses the existing storage system to achieve
- C . Entry-level and mid-range products of the Converged Storage V3 and V5 series use IP Scale-Out, while Converged Storage 18000 V3 uses PCle Scale-Out
- D . PCIE Scale-Out is a Scale-Out technology built on IP, and is widely used in the Dorado V6 series.
A financial customer purchased two Huawei flash storages and deployed them in two computer rooms in the local data center. Engineers now need to deploy active-active services based on the two storages. In the scenario of single arbitration networking, when planning the arbitration network, the engineers can only use 10GE networking for the arbitration link, and cannot use 25GE networking or FC networking.
- A . True
- B . False
