What is UDSet

Product Introduction

The Private Zone UDSet (XXXCloud Dedicated Set) is a cloud computing product based on XXXCloud virtualization services that provides customers with a single-tenant operating environment. Users can exclusively enjoy all the resources of the physical servers in the zone pool, such as CPU, memory, network, etc., featuring security, stability, efficiency, and cost-effectiveness.

The underlying version of the Private Zone (UDSet) uses the Intel CascadelakeR and Intel IceLake CPU platforms, and is compatible with the flagship cloud host FastJet series software stack. Virtual machines created on the hosts in the Private Zone can achieve a maximum network packet rate of up to 10 million PPS and a storage performance of up to 1.2 million IOPS.

Product Advantages

• Isolation: Users exclusively occupy the host, enjoying exclusive access to physical resources such as CPU, memory, NIC, etc., providing high-level isolation that meets strict compliance requirements.

• High Availability: Host-level downtime automatic migration capability; autonomous planning to disperse business-level high availability clusters to ensure service high availability.

• Flexible Deployment: Upon initial allocation, virtual machines can be scheduled to a designated private zone host or automatically scheduled within the zone pool; later, resource topology can be re-planned multiple times.

• Cost-Effective: Equipped with the latest FastJet hardware resources and software stack, delivering outstanding product performance while reducing cloud host costs by up to 25% compared to similar configurations.

Application Scenarios

• Banking, insurance, healthcare industries: Certain businesses have strict compliance and audit requirements and need deployment using exclusive hosts; using a Private Zone (UDSet) can meet compliance requirements and build a secure infrastructure.

• Gaming, real-time audio and video industries: Gaming, audio, and video real-time interactive scenarios require high computation power and stability; a Private Zone (UDSet) can build a high-isolation, high-performance operating environment, unaffected by other cloud tenants.

• Chip, intelligent manufacturing industries: Many design and simulation software require hardware-bound licenses to run; a Private Zone (UDSet) allows maintaining existing hardware resources while enjoying high-performance cloud computing power.

• Medium to large-scale internet companies: Require autonomous planning of physical machine and virtual machine topologies, virtual machine and business segregation; the flexible settings of the Private Zone (UDSet) allow users to customize resource architectures.

• Traditional enterprises: Some traditional companies need to transfer private virtualization environments to the cloud, such as from OpenStack, KVM virtualized environments in physical machine rooms; using a Private Zone (UDSet) utilizes existing physical resources and provides better resource planning.

Key Concepts

Private Zone UDSet

Private Zone (UDSet) refers to a resource pool exclusively for a single user composed of multiple physical machines. Users can create and purchase single or multiple exclusive physical machines within the zone.

Private Zone Host UDHost

A Private Zone Host (UDHost) is a host that provides a tenant exclusive access to physical resources, including CPU count, physical CPU cores, memory size, network, and other physical resources.

Private Zone Cloud Host UHost

A Private Zone Cloud Host (UHost) is a virtual machine autonomously created and run on a Private Zone Host (UDHost) that has virtualization software deployed.

Functional Features

Creation and Deployment

• Creating a Private Zone Cloud Host (UHost): You can specify a zone host to create a zone cloud host or create a zone cloud host based on automatic scheduling rules without specifying a specific zone host.
• Host Association: Flexibly set the topology binding relationship between host and virtual machine, meeting the need for autonomous orchestration in different business scenarios.
• Automatic Placement: When a new Private Zone Cloud Host (UHost) is created, place the new Private Zone Cloud Host (UHost) on a Private Zone Host (UDHost) with “Automatic Placement” enabled. Users can choose to enable or disable the “Automatic Placement” function, and if “disabled,” that Private Zone’s host will not participate in resource scheduling.

CPU Overcommitment Ratio

For scenarios where CPU workloads are not high, users can set a CPU overcommitment ratio greater than 1 to increase the number of usable vCPUs, significantly reducing cloud resource usage costs.

Downtime Migration

When a Private Zone Host is down, the system will automatically select a new host from the XXXCloud backend spare host pool for replacement, achieving migration without changes to user management information.

Shutdown Resource Release

After a Private Zone Cloud Host (UHost) is shut down, it no longer occupies the host’s CPU and memory. When restarted, if the current host resources are insufficient, the Private Zone Cloud Host (UHost) will automatically migrate offline to other hosts in the same zone that have more available resources, maximizing resource cost savings.

Specifications Introduction

Note:

• vCPU Cores = Physical Cores * 2 (Due to host system occupancy, the actual usable vCPU cores = Physical Cores ✖️2 ➖ System Occupied Cores)
• Memory Size: Due to host system occupancy, the actual usable memory size needs to be reduced by the system occupied memory size
