Selected H13-611_V4.5 HCIA Storage Questions Answers

TRUE

FALSE

After using RAID 5 with 6 200G hard drives, the available space is 1200G

NL SAS/SATA hard disks are suitable for data protection using RAID 6, and SAS hard disks are suitable for data protection using RAID 5.

According to protection

C, S2200 V3 can support SSD, SAS, SATA hard drives

OceanStor V3 series products support RAID 0/RAID 1/RAID 5/RAID 10, but not RAID 6

The data is automatically and evenly distributed on the hard disks in the storage pool to avoid uneven heating and cooling of the hard disk, thereby reducing the storage system

Overall failure rate

Overcome the performance bottleneck of the traditional RAID reconstruction target disk (hot spare disk), making the reconstruction bandwidth write bandwidth no longer

It becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed, reduces the probability of double-disk failure, and improves the storage system.

Reliability.

There is no write penalty in RAID2.0+, which overcomes the write penalty in RAID 5 and RAID 6 levels in traditional RAID technology

The impact of the penalty on the write performance of the LUN has greatly improved the performance of the LUN

The data on a single LUN is distributed to many different hard disks, avoiding hard disk hot spots, making single LUN performance and

The capacity has been greatly improved

Automatic allocation: migration to the low-performance layer

Priority allocation from high-performance layer: migration to low-performance layer

Priority allocation from low-performance layer: migration to high-performance layer

Priority allocation from the capacity layer: automatic migration
