Editor to share with you i1 instance to create a full image of the points for attention, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

I1 instance specification family FAQ

What is an i1 instance?

I1 instance is a high I / O local disk storage instance, which is specially designed for business scenarios that require extremely high storage performance.

What are the product features of i1 instance?

In large database business scenarios, it has the ability to read and write tens of thousands to hundreds of thousands of random IOPS with low latency per second.

In large dataset business scenarios such as big data and parallel computing, it has sequential read and write throughput of up to several GiB.

The computational performance is stable, and the ratio of CPU to Memory is 1:4.

Based on the local NVMe SSD disk resources, it can provide hundreds of thousands of random Imax O read and write capabilities while maintaining a latency level of μ s.

Using Intel Xeon E5-2682 v4 (Broadwell) processor, the main frequency is 2.5 GHz,DDR4 memory.

The network performance of the instance corresponds to the computing specification (the larger the computing specification of the instance, the stronger the network performance).

The default IPUBO optimization.

Which industry customers and business scenarios are suitable to use i1 instances?

It is suitable for customers in online games, e-commerce, live video streaming, media and other industries that provide online services to meet the low latency and high performance requirements of block storage in I-hop-O-intensive applications.

It is suitable for business scenarios with high performance requirements and highly available architecture at the application layer, such as NoSQL non-relational database, MPP data warehouse, distributed file system, etc.

Does i1 instance support adaptation and downtime migration?

Currently, modification and downtime migration are not supported. Please refer to the official website for follow-up support time.

Where can I purchase i1 instances?

Currently, you can create i1 instances in the following regions and availability zones:

East China 1: availability Zone F

East China 2: availability Zone B, availability Zone D

North China 2: availability Zone A, availability Zone D

North China 3: availability Zone A

South China 1: availability Zone A, availability Zone B, availability Zone C

Hong Kong: availability Zone B, availability Zone C

South East Asia Pacific 1: availability Zone A, availability Zone B

South East Asia Pacific 2: availability Zone A

Eastern United States 1: availability Zone A

Western United States 1: availability Zone A, availability Zone B

Central Europe 1: availability Zone A

Please pay attention to the notice on the official website for the location and time of subsequent launch.

What should I pay attention to when creating a full image for an i1 instance?

The snapshot feature is not currently supported on the local disk, so when you need to create a full mirror of the i1 specification family instance, it is recommended to create it by combining a system disk snapshot and a data disk (cloud disk) snapshot. Currently, it is not supported to create full images based on instance ID.

What are the data security considerations for i1 instances?

I1 instance is a storage product designed for business scenarios that require extremely high performance of storage Igamot O. The local disk is bound to an instance of a specific specification and cannot be purchased separately or uninstalled and mounted to another instance.

Warning:

The data disk of i1 instance is local, and there is a risk of data loss (such as NVMe SSD failure or host failure). If your application cannot achieve the architecture of data reliability, we strongly recommend that you use cloud disk to build your instance.

The operation and data retention relationship of the local disk instance is shown in the following table.

The above are all the points for attention in creating a full image for i1 instance. Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
