The content of this article is about the similarities and differences between ESSD cloud disk and SSD cloud disk or high-efficiency cloud disk? , has certain reference value, friends in need can refer to it, I hope it will be helpful to you.

ESSD cloud disk FAQ

What is ESSD cloud disk?

ESSD cloud disk, also known as Enhanced (Enhanced) SSD cloud disk, is a new ultra-high-performance cloud disk product launched by Alibaba Cloud. Based on a new generation of distributed block storage architecture, combined with 25GE network and RDMA technology, it provides you with up to 1 million random read and write capabilities per disk and lower single-channel latency.

How reliable is the ESSD cloud disk?

The reliability of ESSD cloud disk is consistent with that of SSD cloud disk and high-efficiency cloud disk, providing a reliability design of 99.9999999%.

What application scenarios are ESSD cloud disks suitable for?

ESSD cloud disk itself has the characteristics of low latency and high performance, and is more suitable for application in the following latency-sensitive or I/O-intensive business scenarios.

Deploy OLTP database. For example, relational databases such as MySQL, PostgreSQL, Oracle or SQL Server.

Deploy NoSQL database. For example, non-relational databases such as MongoDB, HBase or Cassandra.

Run ElasticSearch distributed log. For example, ELK (Elasticsearch, Logstash and Kibana) log analysis.

What are the similarities and differences between ESSD cloud disks and SSD cloud disks or high-efficiency cloud disks?

Common points: ESSD cloud disks and SSD cloud disks are similar to high-efficiency cloud disks. They are cloud disk products based on distributed block storage architecture. They have the characteristics of high reliability, elastic expansion, etc., and support snapshots. , encryption and other data functions.

Differences: The performance of ESSD cloud disks is significantly improved compared to SSD cloud disks and high-efficiency cloud disks. The specific comparison is shown in the table below.

What are the similarities and differences between ESSD cloud disks and SSD cloud disks or high-efficiency cloud disks?

#How are the performance indicators of ESSD cloud disks calculated?

The performance of ESSD cloud disk is linearly related to the capacity. The larger the capacity, the higher the performance. Compared with SSD cloud disk, the performance is greatly improved.

IOPS: min{1800 50 * capacity, 1000000}, starting at 1800 IOPS, increasing by 50 IOPS per GiB, up to 1000000 IOPS.

Throughput: min{120 0.5 * capacity, 4000} MBps, starting at 120 MBps, increasing by 0.5 MBps per GiB, up to 4000 MBps throughput.

How to test the performance of ESSD cloud disk? How to test 1 million IOPS? How should I configure my ECS instance?

You can try to test the performance of ESSD cloud disk through the tool FIO. For specific steps, please refer to How to Stress Test the Performance of ESSD Cloud Disk.

What is the relationship between ESSD cloud disk performance and instance performance?

The storage I/O performance of some instance dimensions has a direct and linear relationship with the instance specifications. For example, the storage I/O performance of the ECS storage-enhanced instance g5se is linearly related to the instance specification. The higher the instance specification, the higher the storage IOPS and throughput you can obtain.

When you create a g5se instance of a certain specification and mount the ESSD cloud disk:

If the total performance of the ESSD cloud disk does not exceed the storage I/O capacity corresponding to the instance specification family, Actual storage performance is subject to ESSD cloud disk performance.

If the total performance of ESSD cloud disks exceeds the storage I/O capacity corresponding to the instance type family, the actual storage performance shall be based on the storage I/O capacity corresponding to the instance type.

For example, after you create an ecs.g5se.xlarge 16GiB instance, the maximum storage IOPS of the instance is 60,000. If an ESSD cloud disk with a storage I/O capacity of 2 TB is mounted ( (single disk IOPS is 101,800), the maximum storage IOPS of this instance can only be 60,000, and cannot reach the 101,800 IOPS of the 2 TB ESSD cloud disk.

The specifications and performance of other ECS storage-enhanced instances g5se are shown in the table below.

What are the similarities and differences between ESSD cloud disks and SSD cloud disks or high-efficiency cloud disks?

How is ESSD cloud disk billed?

The prices of ESSD cloud disks and SSD cloud disks remain the same.

In mainland China, annual subscription is billed on a monthly basis, and the unit price is 1 yuan/GiB/month; pay-as-you-go is billed by the second, and the bill is based on the hourly unit price of 0.0014 yuan/GiB/hour. .

The price of ESSD cloud disks in other countries and regions is to be determined.

Supports prepaid and pay-as-you-go billing methods.

Which regions or availability zones are currently open to ESSD cloud disk resources?

Currently you can apply to purchase ESSD cloud disks in North China 2 (Beijing) Availability Zone G and East China 2 (Shanghai) Availability Zone F.

Other regions will be opened gradually, so stay tuned.

Which instance type families can the ESSD cloud disk be mounted to?

Currently, the ESSD cloud disk product is in public beta. Only the instance type families of the 25GE network (c5, g5, r5, g5se, hfc5, hfg5) support mounting ESSD cloud disks. Other instance type families are not supported for the time being.

If the problem has not been resolved, please submit a work order.
