Chinese-English Translation:

阿里云ESSD(Enhanced SSD,增强型SSD)云盘结合25 GE网络和RDMA技术,能提供单盘高达100万的随机读写能力和单路低时延性能。低时延、快速响应、强大的数据吞吐量的特点,适用于时延敏感的应用或者I/O密集型业务场景。

Alibaba cloud ESSD (enhanced SSD) cloud disk, combined with 25 Ge network and RDMA technology, can provide up to 1 million random read-write capabilities and low delay performance of a single disk. Low latency, fast response and strong data throughput are suitable for delay sensitive applications or I / O intensive business scenarios.

应用场景

Application scenario

ESSD 云盘具备低时延、快速响应、强大的数据吞吐量的特点,适用于时延敏感的应用或者 I/O 密集型业务场景。例如:

ESSD cloud disk has the characteristics of low delay, fast response and strong data throughput, which is suitable for delay sensitive applications or I / O intensive business scenarios. For example:

典型的联机事务处理(Online Transaction Processing,OLTP)关系型数据库,如 MySQL、PostgreSQL、Oracle、SQL Server 等。

Typical online transaction processing (OLTP) relational databases, such as mysql, PostgreSQL, Oracle, SQL server, etc.

NoSQL 非关系型数据库,如 MongoDB、HBase、Cassandra 等。

NoSQL non relational databases, such as mongodb, HBase, Cassandra, etc.

实时分析应用,如 Elasticsearch 分布式日志和 ELK(Elasticsearch、Logstash、Kibana)日志分析等。

Real time analysis applications, such as elastic search distributed log and elk (elastic search, logstash, kibana) log analysis.

容量范围与性能级别的关系

Relationship between capacity range and performance level

对于存储设备而言,不同的容量能达到的性能不同,容量越大,存储设备的数据处理能力越强。所有 ESSD 云盘性能级别的单位容量的 I/O 性能均一致,但云盘性能随容量增长而线性增长,直至达到该性能级别的单盘性能上限。

For storage devices, different capacity can achieve different performance, the larger the capacity, the stronger the data processing capacity of storage devices. The I / O performance per unit capacity of all ESSD cloud disk performance levels is the same, but the cloud disk performance grows linearly with the capacity growth until the single disk performance upper limit of this performance level is reached.

云盘类型

Cloud disk type

类似硬盘,您可以对挂载到 ECS 实例上的云盘做分区、格式化、创建文件系统等操作,并持久化存储数据。根据性能分类,云盘包含以下几类产品。

Like a hard disk, you can partition, format, create a file system and other operations on the cloud disk attached to the ECS instance, and persist the data. According to the performance classification, cloud disk includes the following products.

ESSD 云盘:基于新一代分布式块存储架构的超高性能云盘产品,结合 25GE 网络和 RDMA 技术,单盘可提供高达 100 万的随机读写能力和更低的单路时延能力。

ESSD cloud disk: an ultra-high performance cloud disk product based on the new generation of distributed block storage architecture. Combined with 25ge network and RDMA technology, a single disk can provide up to 1 million random read-write capabilities and lower single path delay capabilities.

SSD 云盘:具备稳定的高随机读写性能、高可靠性的高性能云盘产品。

SSD cloud disk: a high-performance cloud disk product with stable high random read-write performance and high reliability.

高效云盘:具备高性价比、中等随机读写性能、高可靠性的云盘产品。

Efficient cloud disk: cloud disk products with high cost performance, medium random read-write performance and high reliability.

普通云盘:具备高可靠性、一般随机读写性能的云盘产品。

General cloud disk: a cloud disk product with high reliability and general random read-write performance.
