Fully converged virtualization
H3C CAS integrates compute, network, storage, and security virtualization capabilities to deliver higher quality service to higher-tier applications through fault-tolerant resource pooling and automated scheduling. Virtual machines are separated from each other thanks to independent processors, memory, disk I/O devices and network interfaces; The failure of any virtual machine has no impact on other virtual machines on the same physical device, and each virtual machine may be running a different operating system.
Wide interoperability and open interoperability
H3C CAS is an open platform compatible with third-party software and hardware, including x86 servers from major manufacturers, storage arrays, original operating systems, network cards, adapters, etc. It can connect to third-party Openstack-based cloud platforms using a customized REST API to upstream systems, and can work with partner products as fully integrated solutions.
Architecture
The H3C CAS platform is designed to be deployed on hardware without operating systems and includes three main components:
CVK: Cloud Virtualization Kernel,kernel cloud virtualization
CVK is kernel virtualization software that operates between the network infrastructure and the customer’s operating system. For hardware resources accessed by customer operating systems, CVK hides internal differences across disparate hardware; and also eliminates the dependence of the customer’s operating system on hardware devices and drivers. Most importantly, CVK improves the compatibility, reliability, availability, scalability and performance of virtual machine (VM) hardware.
CVM : Cloud Virtualization Manager,manager cloud virtualization
CVM provides automated services for higher-level applications, managing computing resources, network resources, storage resources and other hardware resources in the data center using virtualization software; managed resources include virtualized computing resources, virtualized network interfaces, virtualized storage systems, high availability functions (HA, High Availability), dynamic resource scheduler (DRS, Dynamic Resource Scheduler), dynamic resource extension (DRX, Dynamic Resource Extension), GPU resource pool, virtual machine backup and recovery functions, virtualization management functions based on carrier-grade KVM, management of carrier-grade vSwitch virtual switches, Carrier-grade reliability features, virtualized security management, audit trail interfaces, and more. Thanks to CVM’s open REST interfaces to upstream systems and OpenStack-compatible pluggable interfaces, the platform can connect to third-party cloud management platforms and standard OpenStack cloud platforms, including Havana, Juno, Kilo, Liberty, Mitaka and others, while providing isolation from complex and heterogeneous virtualized infrastructure.
CIC: Cloud Intelligence Centerintelligent cloud center
CIC consolidates infrastructure resources (computing resources, network and storage resources) and corresponding policies into a pool of data center resources. In addition, using CIC, you can create a hybrid cloud for multiple tenants, giving them the ability to order the required amount of resources on demand. On-demand resources may include: multi-tenant storage and security orchestration, cloud platform-based business solutions workflows, cloud-based platform-based security workflows, self-service portal, VMware-compatible virtualization platforms, and more. p.
Functionality
Cluster-based centralized management
H3C CAS provides the creation of clusters using server nodes and virtual machines. H3C CAS provides a clear, hierarchical view that shows the relationships between the data center, host pools, clusters, hosts, and virtual machines, making resource management easier.
It provides the following benefits:
The administrator has the ability to organize, monitor and configure all elements of the IT infrastructure through a unified interface in order to reduce management costs.
A cluster that includes shared resource pools and combines several autonomous nodes not only simplifies management, but also automatically implements high availability features. H3C CAS can instantly restart the desired virtual machines on another node in the cluster, and also supports manual migration of virtual machines if a node fails. In addition, the platform supports migration without interruption within storage systems or between different storage systems, as well as migration of virtual machines between different manufacturers, that is, a running virtual machine can be transferred from one site on which the storage system is located to another site without interrupting the work of the business. applications. This feature offers a cost-effective and highly reliable solution.
H3C CAS supports dynamic resource allocation, allowing you to dynamically change the CPU and memory resources allocated to virtual machines , disks, network cards, etc. without or with interruption.
Manage the entire life cycle of virtual machines
Support for creation, modification, launch , pausing, restoring, hibernating, rebooting, shutting down, cloning, migrating, snapshotting, and other virtual machine operations; simultaneously with support for remote connection to virtual machines through the management console. All operations are performed through a graphical user interface.
Container cluster management
Support for unified management of container clusters and virtual machines in CAS. Providing kubernetes cluster services at the user level; independent kubernetes clusters are available to users. Through intelligent management, monitoring and planning, more flexible use of resources is achieved with the ability to automatically scale the business architecture as needed, offering a more flexible and cost-effective solution for implementing cloud services.
High Availability (HA)
H3C CAS HA consistently monitors virtual machines in resource pools and supports a channel that is unique to each virtual machine for exchanging signals about the current condition. If the current state signals from the virtual machine are lost, CAS will attempt to reboot the failed virtual machine on another server; At the same time, CAS HA tools ensure that important virtual machines on other servers are restarted when the previous server fails and that there are sufficient hardware resources for them in resource pools. CAS HA uses an optimized high-performance clustered file system that allows different servers to access the same storage file using different protocols, such as SAN/iSCSI/NFS.
Dynamic Resource Scheduler (DRS)
In a virtualization environment, when users consolidate applications on physical nodes with fewer resources, virtual machine resources can become a bottleneck, that is, the required amount of resources will exceed the amount of available resources on the physical nodes. DRS offers an automatic mechanism for continuous capacity balancing and the ability to migrate a virtual machine to a host with more resources, so that virtual machines on any nodes have sufficient resources at any time. Even when running virtual machines running SQL, using DRS eliminates the need to monitor the availability of necessary processor resources and memory. Automatic resource provisioning and load balancing also help reduce data center and operational costs.
The status signaling mechanism allows CAS to track utilization percentages for critical important resources such as processors and memory. This feature also allows you to decide whether additional resources need to be allocated based on user-configurable rules. If necessary, the platform can move a virtual machine to another server that has more resources available, or move other virtual machines off the server to ensure that critical virtual machines have sufficient resources.
Dynamic Power Management (DPM)
H3C CAS migrates virtual machines and dynamically powers down idle servers to reduce power consumption in data centers while monitoring resource utilization, such as processors, memory, connections of physical nodes in the cluster. As the load on services increases, H3C CAS wakes up disabled hosts and migrates virtual machines to them for load balancing.
Flexible resource provisioning
H3C CAS allows you to allocate computing resources, network resources, and storage resources depending on business requirements. The allocation of computing resources is carried out based on the limits and reserves of processors and memory for virtual machines; Network resources are allocated based on quality of service (QoS) settings on vSwitches, while storage resources are allocated based on disk input/output operations per second (IOPS) and bandwidth speed limits. At the same time, the parameters of service level agreements (SLAs) are observed, which makes it possible to provide high-priority virtual machines with a larger amount of computing resources, network resources and storage resources, and also avoid influence from neighboring nodes.
Unified management and scheduling of GPU resources
H3C CAS supports resource pool functionality GPU, which enables unified management and scheduling across physical graphics cards (GPUs) and virtual graphics cards (vGPUs). Depending on your GPU direct access settings and GPU virtualization modes, you can allocate and release GPU resources in the GUI, allowing virtual machines to dynamically schedule GPU resources. The platform can provide high-performance computing for industrial enterprises and fast and efficient GPU functionality with less time and cost spent on operational and management tasks.
Physical Device Mapping (RDM)
< p style="font-weight: 400;">H3C CAS supports mapping LUNs on SANs (FC or iSCSI) to virtual machines. The VM can access the physical device directly so that virtual machine data is stored directly on the LUN when creating clustered file systems.
Dual-stack distributed firewall
H3C CAS supports IPv4 and IPv6 addresses. When created by a virtual machine manager, CAS will provide the ability to tailor vFW virtual firewall policies through the process of selecting an address type based on specific needs. The vFW distributed virtual firewall allows you to move the data center security boundary to the virtual switch level. Firewalls on virtual vNICs can offer not only differentiated security policies for different vNICs, but also the necessary balance between performance and flexibility. Security policies remain on virtual machines when these machines are migrated between hosts.
Affordable disaster recovery
H3C CAS supports transparent scheduled backup and instant backup. H3C CAS offers a fast and simple mechanism for protecting data for virtual machines by removing duplicate data.
The advantages of this solution:
Snapshot-based backup, without interrupting business systems.

In addition, the platform provides administrators with a convenient interface for reviewing, auditing and saving information about nodes and virtual machines, as CAS provides functions for exporting lists of nodes and virtual machines in CSV format, collecting information from cloud resources, node pools or clusters.
Visual virtualization topology
H3C CAS displays the relationships between clusters, nodes, virtual machines, network resources and storage resources in a graphical interface, including the ability to display a virtual topology based on computing resources; virtual topology based on virtual switches vSwitches and virtual storage topology based on LUN numbers of storage systems.
One-click functions
H3C CAS supports one-click operations such as one-click status check, one-click resource analysis, one-click storage cleanup, one-click virtual machine recovery, greatly simplifying everyday complex operations. For example, with just one click you can check the status of a virtualized platform, resulting in a dynamic check report with optimization recommendations; At the same time, with one click, you can start cleaning up invalid storage volumes on the shared storage system to free up space and improve storage efficiency.
USB port redirection over the network
H3C CAS supports USB port redirection technology over the network. When moving virtual machines between hosts, communication between the virtual machines and the USB port will not be disrupted. The service system provides efficient operation of USB without the use of third-party support tools.
VxLAN-based network virtualization
H3C CAS supports distributed virtual vSwitches based on standard VxLAN encapsulation technology, which isolates the virtualized network from the physical network. Virtual machine migration can occur over the Layer 3 physical network while synchronizing security policies. Moreover, in total, customers can create up to 16 million isolated virtual networks, which allows them to overcome the limit of 4 thousand VLANs and create a secure virtual network for multiple tenant users.
< h3>Dynamic Resource Expansion (DRX)
H3C CAS supports DRX technology, which works based on traffic load. H3C CAS allows virtual machines to be dynamically cloned or deleted based on various parameters such as processors, memory and connections to suit changing business requirements. When there is a surge in traffic or an influx of users, CAS detects the most loaded virtual machines and quickly clones them to increase the number of virtual machines using a load balancing mechanism to expand system capacity; After the peak load has passed, CAS will remove redundant virtual machines. This ensures that computing resources are provisioned on demand.
Non-disruptive migration between data centers
H3C CAS allows connect separate resource pools across multiple data centers and ensure business continuity by seamlessly migrating virtual machines between multiple data centers, eliminating the constraints of having to deploy IT resources locally and offering enterprises the ability to manage all IT globally -resources.
Comprehensive failure recovery mechanisms
H3C CAS supports highly reliable failure recovery mechanisms. The same virtual machines run on different nodes, and if the primary node fails, the load is immediately transferred to the backup node, ensuring zero downtime and ensuring that real-time business-critical processes are not disrupted.
