Description
High I/O ITA5
Characterized by high random IOPS, high Throughput, and low access latency, it is suitable for I/O intensive applications such as high-performance databases with strict requirements on disk read/write operations and latency.
Note:
This instance specification family is in Beta Testing, and we welcome your suggestions and feedback.

High I/O Instance Family

The High I/O ITA5 Instance is the latest generation of high I/O instances designed specifically for I/O-intensive workloads. Based on NVMe SSD instance storage, it offers low latency, ultra-high IOPS, and high throughput storage resources at a lower cost. Suitable for high-performance relational databases, Elasticsearch, and other I/O-intensive services.

Instance Characteristics

The new generation of Tencent Cloud's self-developed StarSea dual-socket server, equipped with the AMD EPYC™ Bergamo processor.
Equipped with AMD EPYC™ Bergamo Processor, Turbo Boost up to 3.1GHz.
Instance network performance is matched to specifications; higher specifications enable stronger network forwarding performance and higher internal network bandwidth limits.
Utilizing NVMe SSD for instance storage, it provides low latency and ultra-high IOPS.

Application scenario

High-performance databases, NoSQL databases (e.g., MongoDB), clustered databases.
Online Transaction Processing (OLTP) systems, Elasticsearch search, and other I/O-intensive applications requiring low latency.

Instance Requirements

If the local hard disk is damaged, we support online disk replacement operations.
If a cloud server instance has already experienced downtime, we will inform you and proceed with maintenance operations.
An ITA5 instance not having monitoring components installed means the platform cannot monitor the instance as thoroughly. If the instance fails, normal notifications cannot be sent, Please activate cloud monitoring during purchasing.
ITA5 instances can be used as annual and monthly subscription instances and on-demand billing instances.
Only in Virtual Private Cloud can ITA5 instances be launched.
ITA5 instances do not support adjusting configuration or the 'shutdown not charged' feature.
ITA5 instances support purchasing configuration; please see the instance specifications below.
The instance supports up to 160G of network bandwidth, depending on the instance kernel version and running environment support. When pps exceeds 10 million and bandwidth is greater than 50Gbps, the kernel protocol stack causes significant network performance loss. In such cases, the bandwidth measured by netperf testing may not meet expectations. The DPDK method can be used to shield the differences of the cloud service kernel protocol stack, accessing the true network performance of the instance. For testing methods, please refer to High-throughput network performance testing.
