ZStack Cloud offers the BareMetal Management service that provides your applications with dedicated physical servers, ensuring the high performance and stability of your key applications. After your servers are configured well and the related preparations are completed, you can deploy Bare Metal (BM) chassis in bulk on the UI. After the deployment succeeds, you can use these BM chassis to create BM instances. With preconfigured templates, you can achieve unattended batch installation for BM instance operating systems. In addition, you can configure a business network for BM instances and easily manage the entire lifecycle of these BM instances.
The BareMetal Management service is a separate feature module. To use this service, purchase both the Base License and the Plus License of BareMetal Management. The Plus License cannot be used independently.
Basic Workflow
How does the BareMetal Management service work? A deployment server provides two types of service: DHCP and FTP. Specifically, the deployment server can instruct multiple BM chassis to be started through a PXE NIC, and can allocate dynamic IP addresses with the DHCP service. In addition, BM chassis can download related software packages from the deployment server with the FTP service, of whose packages can be applied to the operating system installation of the BM instance, as shown in BareMetal Management Network Topology.
Key Features and Benefits
- Provides applications with dedicated physical servers to ensure the high performance and stability of your key applications.
- Deploy deployment servers independently as recommended, which can meet the requirements for the host high availability scenario of multiple management nodes. This also simplifies the network environment and helps to avoid DHCP conflicts. In addition, you can attach an independent deployment server to each BM cluster, which helps to avoid a single point of failure and improve greatly the deployment rate.
- Helps create BM chassis in bulk on the UI via either the manual creation or template file import. You can also add IPMI addresses in bulk to deploy efficiently BM clusters, which increases O&M efficiencies.
- Helps to quickly generate configuration files by using preconfigured templates to achieve unattended batch installation for BM instance operating systems.
- Enables you to customize the installation of your operating system. Supported operating systems: custom operating system of the Cloud and the mainstream Linux distributions (RHEL/CentOS, Debian/Ubuntu, and SUSE/openSUSE).
- Supports flat network. Specifically, BM instances and VM instances on the same L2 network can reach each other without routing to each other by gateways.
Typical Usage Scenarios
- High-Security and Strict Management Scenario
Financial industry, security industry, and others have rigorous standards for the business compliance and business data security. With the BareMetal Management service, they can ensure their exclusive use of resources, data isolation, strict supervision and control, and effective tracking.
- High-Performance Computing Scenario
In high-performance computing scenarios, supercomputing centers, gene sequencing companies, and other entities require high computing performance, high stability, and accurate real-time update for servers. Sometime later, business performances will be affected by the performance loss and hyper-threading brought by visualization. In this regard, to deploy BM cluster to a certain scale, meet the strict requirements for the high performance computing.
- Key Database Scenario
In some entities, some key database businesses cannot be deployed on normal VM instances, and must be loaded on the physical servers that can protect their exclusive resources, network isolation, and performances. To meet this requirements, use the BareMetal Management service that provides exclusive, high-performance physical servers for one or more appliances.
