When creating a thin LUN, it cannot be allocated a larger capacity than the available free space in the storage pool

Thin LUN cannot be converted into Thick LUN

When creating a thin LUN, the initial allocated capacity can be used without specifying

The types of LUNs on a storage pool must be the same, either all are Thin LUNs or all are Thick LUNs

TRUE

FALSE

Cloud computing (cloud computing) is an increase, use and delivery model of Internet-based related services, usually

Involves the provision of dynamically scalable and often virtualized resources via the Internet

Social media (social media) is a virtual community that people use to create, share, exchange opinions, opinions and experiences

And web platform

CPS (Cyber ​​Phsical System) includes ubiquitous environmental awareness in the future, embedded computing, network communication

System engineering such as Xinhe Network Control is a physical system with functions of computing, communication, precise control, remote collaboration and autonomy

In the new ICT era, the migration of ICT systems from supporting systems to production systems

When it has been stored in the correct file format

When the data has been stored in digital form

When the enterprise understands the meaning of data and extracts the content needed for decision-making

When the data is verified to be correct

For host layer disaster recovery, host layer replication will occupy certain host resources, which will affect the application system

The initial construction cost of network layer disaster recovery is relatively low, and many manufacturers can provide solutions

Array layer disaster recovery, the arrays at both ends must be products of the same manufacturer, unable to solve the heterogeneous problem

Host layer disaster recovery is implemented on the host side, without considering the compatibility between the underlying devices

Regardless of whether disaster recovery or backup solutions are used, compared with data during system failure, data for disaster recovery cannot be lost

Avoided

After the disaster, I hope to immediately access the backup on the remote device

The restored data hopes to meet the current work requirements immediately

The traditional use of software for data backup still has usage scenarios

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

Hot spare space cannot cross engine

RAID 2.0+ uses an independent hot spare disk

Chunk size and Extent size are not adjustable

Automatically reserve a certain amount of hot spare space in the hard disk domain according to the hot spare strategy
