Class topic
Post 1. How Do I Apply for and Use an EVS Disk(with HUAWEI CLOUD)
The Elastic Volume Service(EVS) provides block storage for Elastic Cloud Services(ECSs). Featuring advanced data redundancy and cache acceleration, EVS offers high availability and durability with an extremely low latency. Attach EVS disks to ECSs, then format them, give them file systems, and store data on them. As your business grows and your current EVS capacity is insufficient, expand the capacity of your EVS disks...(More)
Post 2. Solution Description Elastic Volume Service (EVS)
The Elastic Volume Service (EVS) is a scalable virtual block storage service that is based on the distributed architecture. You can create EVS disks and attach them to servers. The method for using EVS disks is the same as that for using traditional disks on physical servers...(More)
Post 3. Differences between EVS, OBS and SFS
Do you know the difference between EVS, OBS and SFS? Service definition application scenario comparison...(More)
Post 4. Backing up an EVS disk
VBS only protects Elastic Volume Services associated with a backup policy. These backup policies include incremental backup, full backup, and replication. Incremental backup performs a full backup for the first time only….(More)
Post 5. Expanding the Capacity of an EVS Disk
As your business grows, the available capacity of your current EVS disks may not meet your volume requirements. You may want to expand their capacity. For system disks, add capacity to expand them. For data disks, either add capacity or apply for new disks to attach to the instance…(More)
Class Q&As
After attending this class, please answer the following questions and comment with the answers below this post.
Q1.(True or False) A hybrid cloud interconnects with Huawei CLOUD EVS open APIs to provide public cloud EVS disks for tenants. EVS can only attach to Huawei Cloud ECSs in the same VDC.
A: True
B: False
Q2. (Multiple-Answer Question) Which of the following statements about EVS are correct?
A. EVS is a scalable virtual block storage service that is based on the distributed architecture.
B. Compared with traditional disks, EVS disks deliver higher data reliability and I/O throughput capabilities.
C. EVS disks can be used for file systems, databases, and system software and applications that require block storage devices.
D. Data can only be accessed on the internal network of data centers.
Q3. (Single-Answer Question)Which of the following is the correct sequence for backing up EVS disks?
1. Apply for space. 2. Create your backup policy. 3. Select your EVS disk. 4. Perform a manual backup.
A. 1->2>3>4
B. 1>3>4>2
C. 2>3>1>4
D. 2>3>4>1
Q4. (Multiple-Answer Question) Which of the following statements about EVS capacity expansion are correct?
A. For date disks, you can only expand the capacity of existing disks.
B. For system disks, you can either expand the capacity of existing disks or add new disks and attach them to instances.
C. When you expand the capacity of a disk online, the instance to which the disk is attached must be in the Running or Stopped state.
D. Capacity expansion cannot be performed when the disk status is Reserved or Maintenance.
Q5.(True or False) EVS uses distributed storage, and data is stored in multiple identical copies, ensuring zero data loss. Data durability reaches 99.9999999%.
A. True
B. False
Hope you get good grades, come on!
