What is UDSet

Product Introduction

The 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 layer of the UDSet (Private Zone) in this version adopts the CPU platforms of Intel Cascadelake-R and Intel IceLake, and the upper layer is compatible with the software stack of the flagship cloud host series “Outstanding”. In terms of performance, the virtual machines created on the host of the UDSet can achieve a maximum network packet volume of 10 million PPS and the highest storage performance of 1.2 million IOPS.

Product Advantages

• Isolation: Users exclusively occupy the host machine and enjoy physical resources such as CPU, memory, and network cards, bringing a high level of isolation that meets strict compliance requirements.

• High Availability: The host-level automatic migration capability for downtime; it is possible to independently plan and disperse high-availability clusters at the service level to ensure service high availability.

• Flexible Deployment: During initial allocation, virtual machines can be scheduled to specified UDSet host machines or automatically scheduled in the zone pool; resource topology diagrams can be re-planned twice or multiple times in the later stage.

• High Cost-effectiveness: Equipped with the latest Outstanding hardware resources and software technology stack, while bringing excellent product performance, the cost of cloud hosts can be reduced by up to 25% compared to the same configuration.

Application Scenarios

• Banking, Insurance, Healthcare and Other Industries: Some businesses have strict compliance and auditing requirements, requiring deployment through exclusive host machines. Using UDSet (Private Zone) can meet compliance requirements and build a secure infrastructure.

• Gaming, Real-time Audio and Video Industries: In real-time interactive scenarios such as gaming and audio/video, both computing power and stability are extremely demanding. UDSet (Private Zone) can build a highly isolated and high-performance operating environment, unaffected by other cloud tenants.

• Chip, Intelligent Manufacturing and Other Industries: Many design and simulation software require hardware-bound licenses to run. UDSet (Private Zone) allows users to retain hardware resources while enjoying high-performance cloud computing power.

• Internet Companies of a Certain Scale: Requiring independent planning of the topology between physical machines and virtual machines, as well as business segmentation between virtual machines. The flexible configuration functions of UDSet (Private Zone) enable users to customize resource architectures.

• Traditional Enterprises: Some traditional enterprises need to migrate private virtualization environments to the cloud, such as transitioning from physical machine rooms (e.g., OpenStack, KVM virtualization environments) to cloud platforms. UDSet (Private Zone) can leverage existing physical resources and optimize resource planning.

Key Concepts

Private Zone UDSet

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

Private Zone UDHost

The UDHost is a host where a tenant exclusively owns physical resources, including the number of CPUs, physical CPU cores, memory capacity, network, and all other physical resources.

Private Zone UHost

The UHost refers to a virtual machine independently created and run on a UDHost with virtualization software deployed.

Functional Features

Creation and Deployment

• Create a UHost: UHost can be created by designating a UDSet host, or without designating a specific host, following automatic scheduling rules.
• Host Association: Flexibly set the topological binding relationship between hosts and virtual machines to meet the needs of independent orchestration in different business scenarios.
• Automatic Placement: When creating a new UHost, it will be placed on a UDHost with the “Automatic Placement” function enabled. Users can choose to enable or disable this function. If disabled, the UDSet host will not participate in resource scheduling.

CPU Oversubscription Ratio

For scenarios with low CPU load, users can set a CPU oversubscription ratio greater than 1 to increase the number of available vCPUs, significantly reducing cloud resource costs.

Downtime Migration

When a UDSet Host experiences downtime, the system automatically selects a new host from XXXCloud’s backend standby pool for replacement, ensuring seamless migration without changes to user management information.

Shutdown Resource Release

When a UHost shuts down, it no longer occupies the host’s CPU or memory. Upon restart, if the current host lacks sufficient resources, the UHost will automatically migrate offline to a less-utilized host within the same zone, optimizing resource costs.

Specifications Introduction

Notes:

• vCPU Cores = Physical Cores * 2 (Due to host system occupancy, the actual usable vCPU cores = Physical Cores ✖️2 ➖ System Occupied Cores)
• Memory Size: The actual usable memory needs to subtract the system-occupied memory due to host system resource consumption.
