Elastic bare metal server FAQ

What is an elastic bare metal server?

The elastic bare metal server combines the respective advantages of the physical machine and the cloud server to achieve ultra-strong and ultra-stable computing power. By using the virtualization 2.0 technology independently developed by Aliyun, your business applications can directly access the processors and memory of elastic bare metal servers without any virtualization overhead.

Elastic bare metal servers have complete processor features at the physical machine level (for example, intel VT-x), as well as the advantage of resource isolation at the physical machine level, which is especially suitable for applications that deploy traditional non-virtualized scenarios on the cloud.

What is the essential difference between an elastic bare metal server and a traditional CVM (virtual machine) and a traditional physical machine?

For the features and performance differences between elastic bare metal servers and traditional CVM (virtual machines) and traditional physical machines, please refer to Elastic bare Metal servers (Dragon) and Super Computing Cluster (SCC) servers.

What are the technological innovations of elastic bare metal servers?

Through self-developed chips and Hypervisor system software, as well as software, hardware and chip technologies such as redefining server hardware architecture, elastic bare metal servers have created the world's leading innovative computing architecture that deeply integrates the characteristics of physical and virtual machines.

Elastic bare metal server creates a new type of CVM, which can seamlessly interface with other computing products in the product family, such as storage, network, database, etc., and is fully compatible with the mirror system of ECS CVM instances, thus building resources based on your business scenarios.

What value does the elastic bare metal server bring to you?

Elastic bare metal servers realize customer value through technological innovation. Specifically, the elastic bare metal server achieves the following design goals:

Any Stack on Alibaba Cloud

The elastic bare metal server takes into account the performance advantages and complete features of the physical machine, as well as the convenient management and price advantages of the cloud server. The launch of the elastic bare metal server further solves your strong demand for high-performance computing and helps you build a new hybrid cloud. Elastic bare metal server not only has the flexibility and flexibility of virtual machine, but also has all the characteristics and advantages of physical machine, so it also has the ability to virtualize again. Offline private clouds can seamlessly move up without worrying about the performance overhead caused by nested virtualization, providing a new way for you to get on the cloud.

Users monopolize computing resources

As a cloud elastic computing product, the elastic bare metal server surpasses the performance and isolation of the physical machine in the current era, allowing you to monopolize computing resources without virtualization performance overhead and feature loss. CPU specifications support 8-core, 16-core, 32-core, 96-core and other specifications, and support ultra-high frequency instances. Take 8-core products as an example, elastic bare metal server instances support ultra-high frequency to 3.7 GHz ~ 4.1 GHz. Compared with similar products, it can provide better performance and faster response for games and financial services.

Encrypted computing

In terms of security, in addition to physical isolation, the elastic bare metal server uses an Intel ®SGX to better ensure the security of your data on the cloud, which ensures that encrypted data can only be calculated in a secure and reliable environment. This chip-level hardware security is equivalent to providing a safe for the data of users on the cloud, and users can control the whole process of data encryption and key protection.

Supercomputing cluster

For high-performance computing scenarios, supercomputing cluster (Super Computing Cluster, referred to as SCC) service products based on elastic bare metal servers will also be launched, which will interconnect RDMA (Remote Direct Memory Access) networks with high bandwidth and low latency among nodes in the cluster, ensuring high parallel efficiency of high-performance computing applications. At the same time, the speed of RoCE (RDMA over Converged Ethernet) network reaches the performance of Infiniband network, and can support a wide range of Ethernet-based applications. The SCC cluster based on elastic bare metal servers, together with computing products such as ECS and GPU CVM, provides parallel computing resources comparable to supercomputing centers for E-HPC, an elastic high-performance computing platform, so that supercomputing on the cloud can be truly realized.

How is the network performance of the elastic bare metal server?

The network performance of elastic bare metal server instances is related to the instance specifications: low network performance of small size instances and high network performance of large size instances. For network performance corresponding to different instance specifications, please refer to the instance specification family.

What disk types are supported by elastic bare metal servers? How many data disks can be mounted?

Elastic bare metal servers support efficient cloud disks and SSD cloud disks, and can mount up to 16 data disks.

How to create an elastic bare metal server instance?
