Elastic Bare Metal Server

Memory-optimized EBM

Refer to the following information to select the instance type that meets your business requirements. Ensure that the selected instance type provides at least the minimum CPU and memory required by your business.

warning

For information about instance types, estimated instance fees, instance type changes, and instance naming rules, refer to Instance types and specifications.

For information about Elastic Bare Metal (EBM) instances, refer to Elastic Bare Metal (EBM) Overview.

Instance type	Scenarios
Memory-optimized Elastic Bare Metal (EBM) ebmr3id	Memory-optimized dedicated computing provides dedicated physical computing resources, making it suitable for high-performance databases, memory databases, and enterprise-level applications with large memory requirements that need direct access to physical resources.

Limits

The specifications and lifecycle of SSD local disks are tied to the instance. You cannot purchase, mount, unmount, or scale up SSD local disks independently.

When you delete an instance, data on the local disk will be automatically cleared. Please make sure to back up your data in advance.

If the physical machine crashes or goes down, or if the local disk is damaged, there is a risk of data loss on the local disk. Please do not store data that needs to be stored long-term on the local disk, and promptly perform data backups.

We recommend that you adopt a high availability architecture by distributing your workloads across multiple instances or using volume backups to ensure high availability and data reliability.

If the data architecture of your application is not reliable, we strongly recommend that you use cloud volumes for data backup.

Specifications and features

type	Performance
Compute	ecs.ebmr3id.48xlarge： Processor: 4th generation Intel® Xeon® Scalable processors (Sapphire Rapids), processor base frequency 2.6 GHz, all-core turbo frequency 3.1 GHz The processor-to-memory ratio is 1:10.7. ecs.ebmr3id.60xlarge： Processor: 5th generation Intel® Xeon® Scalable processors (Emerald Rapids), processor base frequency 2.6 GHz, all-core turbo frequency 3.0 GHz The processor-to-memory ratio is 1:8.5.
Storage	Supports Enhanced SSD Volumes, and up to eight volumes can be mounted, including one system volume. High-performance local SSDs (high IOPS, high throughput, low access latency) Storage I/O performance is related to computing specifications; higher specifications deliver better performance.
Network	Maximum network bandwidth: 96 Gbit/s Maximum throughput: 36 million PPS

Details of specification metrics

tip

Due to differences in business scenarios, maximum throughput (PPS) varies significantly. Therefore, it is recommended that you perform a business stress test to understand the performance of the instance, so that you can select the appropriate instance type.
