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 have extremely high requirements for storage I/O performance.

What are the product features of i1 instance?

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

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

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

Based on local NVMe SSD disk resources, it provides hundreds of thousands of random I/O read and write capabilities while maintaining μs-level latency.

Uses Intel Xeon E5-2682 v4 (Broadwell) processor, clocked at 2.5 GHz, DDR4 memory.

Instance network performance corresponds to computing specifications (the larger the instance computing specifications, the stronger the network performance).

Default I/O optimization.

Which industry customers and business scenarios are suitable for using i1 instances?

Suitable for industry customers who provide online services such as online games, e-commerce, live video, media, etc., to meet the low latency and high I/O performance requirements of I/O-intensive applications for block storage .

Suitable for business scenarios that have high requirements for storage I/O performance and high-availability architecture at the application layer, such as NoSQL non-relational databases, MPP data warehouses, distributed file systems, etc.

Does the i1 instance support configuration changes and downtime migration?

Currently, configuration changes and downtime migration are not supported. Please pay attention to the official website notification for subsequent support time.

In which regions can i1 instances be purchased?

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

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

The local disk currently does not support the snapshot function. Therefore, when you need to create a full mirror for an i1 specification family instance, it is recommended to create it by combining a system disk snapshot and a data disk (cloud disk only) snapshot. . Currently, creating a full image based on instance ID is not supported.

What are the data security precautions for the i1 instance?

i1 instances are storage products designed specifically for business scenarios that have extremely high requirements for storage I/O performance. The local disk is bound to instances of specific specifications and cannot be purchased separately or uninstalled and combined. Mount it to another instance for use.

Warning:

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

The operation and data retention relationship between local disk instances is as shown in the following table.
