When demarcating a performance issue of Huawei flash storage, engineer A finds that the latency observed on the compute side is much longer than that on the storage side. This indicates that the issue most possibly occurred on the storage, for example, the disk performance upper limit has been reached.
To analyze disk performance, we can first use tools (such as free, top, vmstat, and pidstat) that support many indicators, and then determine the I/O source and analyze the file system and process I/Os.
Routine management on Huawei flash storage systems involves power-on and power-off. Which of the following statements is false about power-on and power-off?
Which statements are false about software Installation of Huawei OceanStor Pacific series storage systems?
For device reliability purposes, during the quick Installation of OceanStor Pacific 9550, engineers need to connect power cables on the storage device supplied by two power modules to separate power distribution units (PDUs).
When delivering a Huawel OceanStor Pacific scale-out storage project, an engineer introduced the end-to-end data Integrity check technology of scale-out storage to the customer. Which of the following statements are false about this technology?
The backup and archiving scenario mainly involves sequential read of large I/Os, where there are more read I/Os than write I/Os and hot data areas are obvious. The service characteristics of this scenario are the same as those of the database OLAP scenario.
An industry customer purchases several Huawei flash storage devices for service deployment. During routine management, an engineer finds that a controller of one device is faulty, but the fault is common, so the engineer does not need to perform emergency handling.
When delivering a Huawei OceanStor Pacific storage project, a Huawei engineer vigorously promoted the SmartEncryption feature of scale-out storage to customers. Which of the following statements is false about this feature?
An industry customer has purchased a Huawei OceanStor Pacific scale-out storage system for service deployment. An engineer configures NFS file sharing on the storage system through NFSv4.0. Which of the following commands can the engineer use to switch the user view to the developer view on the command line interface (CLI)?
