Dear All Today we are going to learn about FusionCompute architecture of key functions
Customer Benefits
Improving Resource Utilization
Benefits
Hardware utilization is improved
Power consumption is reduced
IT O&M efficiency is enhanced, and therefore fewer system administrators are required
The OS and hardware are decoupled
Concepts
FusionCompute CNA Server Virtualization
FusionCompute VRM
VRM
The management node of FusionCompute. It allocates and schedules resources for FusionCompute and supports centralized operation and maintenance (O&M), resource monitoring, and resource management
NUMA(Non-Uniform Memory Access): A technology that improves the performance of physical servers. This technology allocates CPU and memory resources of a physical server to multiple NUMA nodes. Each NUMA node can work independently. Efficiency for memory access on the same NUMA node is high, and memory access across NUMA nodes is controlled by a lock mechanism
Affinity-aware Interrupt Scheduling: The virtualization layer automatically binds virtual devices, services, and virtual interrupt and threads involved in I/O operations and allocates resources to the operations based on NUMA nodes. The virtual interrupts and threads, and data are processed on the same NUMA node, significantly improving I/O data processing efficiency
VIMS File System
Features
Virtual Image Management System (VIMS), a high-performance cluster file system, is the basic
technology of advanced features, such as thin provisioning, snapshots, and storage migration.
The VIMS is compatible with FusionCompute SAN devices, IP SAN devices, NAS devices, and local disks.
The VIMS supports fixed, dynamic, and delta VHDs. Application Scenarios It is used for VMs that require advanced storage features, such as the storage live migration, snapshot, and linked cloning.
Constraints
If the VIMS is used, a computing cluster can contain a maximum of 32 hosts
VM Live Migration
Features
Based on the memory compression technology, VM live migration efficiency is doubled. VM disks can be live migrated between shared storage devices and local disks.
Application Scenarios
VM live migration applies to the services that can tolerate short interruptions but must be recovered quickly, for example, lightweight database services and desktop.
Dynamic Resource Scheduler
Features
In a cluster, FusionCompute automatically migrates VMs based on specified load balancing policies.
Optimized load balancing algorithms prevent invalid VM migration.
Benefits
Improves service performance.
Prevents traffic congestion at peak hours.
Dynamic Power Management
Features
The system automatically powers on or off some physical servers, thereby reducing the number of migrated VMs and ensuring that some physical servers are hibernated and can quickly provide resources for new services.
Benefits
In the nighttime, when the service loads are light, resources on physical servers are not fully utilized so that the VMs can be automatically merged, and idle physical machines can be powered off.
In the daytime, when service loads are heavy, resources on running physical servers become insufficient so that power-off physical servers can automatically power on to take over VMs on heavy-load physical servers. This mechanism protects QoS for VMs.
Storage Live Migration
Features
The migration bandwidth is controllable, thereby preventing service interruptions.
Volumes can be migrated from one cluster to another.
Application Scenarios
Maintenance of power-off storage systems
VM storage I/O performance optimization
Efficient storage capacity management, such as storage fragment reclamation
Hopefully this will help you to understand Fusioncompute.
