H3C CAS also offers plenty of alarm policies, and support sending notifications via emails or messages to operators. The exclusive one-click O&M and visual topology support one-stop operation and management for operators.
Fully Converged Virtualization
H3C CAS integrates virtualization of computing, networking, storage and security, serves better for upper application layers with resilient resource pool and automatic dispatch. VMs are separated from each other with independent CPU, memory, I/O of disk and network, when any VM is down, there is no influence on other VMs in the same physical device, and the operating systems between VMs can be heterogeneous.
Wide Compatibility& Open Cooperation
H3C CAS is open and compatible with 3rd party software and hardware platform, including x86 servers of mainstream manufacturers, storage arrays, original operating systems, NIC, HBA and etc. It can connect with 3rd party Openstack-based cloud platform via customized northbound REST API and cooperate with partners to build all-round integrated solutions.
H3C CAS platform is based on bare-metal framework and includes three core components,
CVK: Cloud Virtualization Kernel
CVK is a virtualization kernel software which runs between network infrastructure and customer’s operating system. For hardware resources access by customer operating system, CVK shields the underlying differences among heterogeneous hardware; and eliminate the dependency of customers’ operating system on hardware devices and drivers. Above all, CVK enhances hardware compatibility, reliability, availability, scalability and performance of VMs (virtual machines).
CVM: Cloud Virtualization Manager
CVM provides automatic services for upper layer applications and manages computing,
network, storage and other hardware resources in a data center through virtualization software; manageable resources including virtualized computing, virtualized network, virtualized storage, HA(High Availability), DRS(Dynamic Resource Scheduler), DRX(Dynamic Resource eXtension), GPU resource pool, VM recovery & backup, carrier-grade KVM virtualization management, carrier-grade vSwitch management, carrier-grade reliability management, virtualized security management, log audit interface and etc. Since CVM provides open northbound REST interfaces and plug-in interfaces which are compatible with OpenStack, it can connect with 3rd parties’ cloud management platform and the standard OpenStack cloud platform, including Havana, Juno, Kilo, Liberty, Mitaka and etc and at the same time shields the complicated and heterogeneous virtualized infrastructure.
CIC: Cloud Intelligence Center
CIC consolidates infrastructure resources (computing, network & storage) and corresponding policies into a data center resources pool. CIC can also build a multi-tenant hybrid cloud and let tenants to order the resources on demand. On demand resources includes: organize, multi-tenant data & security, cloud business workflow, cloud security workflow, self-service portal, VMware-compatible virtualization platforms and etc.
Cluster-based Centralized Management
H3C CAS forms cluster using server hosts and VMs. H3C CAS provides clear hierarchical view, and demonstrates relationships of Data Center, host pools, cluster, hosts and VMs to simplify workload of resources management.
The benefits are:
The administrator can organize, monitor and configure all IT elements via a unified interface to reduce management cost.
The cluster, providing a share resources pool and converged with multiple standalone hosts, not only reduces complexity of management but provides the instinct high availability. H3C CAS can instantly restart the influential VM on another host in the cluster or migrate the VM manually when a host breaks down. It also supports online migration of storage and cross-storage and cross-vendor migration of VMs, which means that a running VM can migrate from one storage site to another one without business interruption. The function proposes a cost-effective and highly available solution.
H3C CAS supports dynamic resource allocation to adjust VM resources, such as CPU, memory, disk, NIC and etc on-line or offline dynamically.
Full Lifecycle Management of VM
Support VMs create, modification, start, suspend, restore, sleep, reboot, shutdown, clone, migration, snapshot and etc; and at the same time support remote connection to VM through the management console. All operations are based on GUI.
HA (High Availability)
H3C CAS HA monitors VMs in the resources pool consistently and maintains heartbeat between VMs uniquely. When a VM loses its heartbeat, CAS will try to reboot the failed VM on another server, CAS HA shall guarantee the influential VM reboot on other servers when its previous server breaks down and at the same times ensure there is enough hardware resources in the resources pool. CAS HA utilizes the optimized high performance cluster file system and allows different servers to visit the same storage file via different storage protocols, like SAN/iSCSI/NFS.
DRS (Dynamic Resource Scheduler)
In the virtualization environment, when users integrate applications to physical hosts with less resources, the resources on VMs will become bottleneck and resources required will exceed the available resources on the physical hosts. DRS introduces an automatic mechanism to balance capacity continuously and migrate VMs to a host with more available resources to ensure each VM at any nodes has enough resources in any time. Even though there are VMs running SQL, once using DRS, there is no need to monitor the availability of CPU and memory. The automatic resource allocation and load balance can also reduce the cost of Data Center and cost of operations.
The heartbeat mechanism can help CAS to monitor the utilization ratio of critical resources such as CPU and memory. The function can also decide whether a host needs more available resources according to users’ customized rules. If necessary, it will migrate the VM to another server which owns more available resources or move out other VMs on the server to ensure enough resources for the critical VMs.
DPM (Dynamic Power Management)
H3C CAS migrates VMs and shut idle servers dynamically to reduce consumptions in Data Centers via monitoring resources utilization ratio, such as CPU, memory, connections of physical hosts in the cluster. When service load increases, H3C CAS will wake up shutdown host and migrate VMs dynamically for load-balancing.
Flexible Resource Allocation
H3C CAS can allocate computing resources, networking resources, storage resources based on business demands. The allocation of computing resources is based on the limit and reservation of VM CPU and memory; networking resources is allocated based on QoS setting in vSwitches while storage resources is allocated based on disk IOPS (Input and Output Per Second) and the speed
limitation of throughput. SLA (Service-Level Agreement) is satisfied and to ensure high-priority VMs running with better capability of computing, networking and storage, as well as to avoid adjacent interference.
GPU resource unified management and scheduling
H3C CAS can support the function of GPU resource pool, which can realize the unified management and schedule of the physical GPU and vGPU. According to the GPU pass-through and GPU virtualization modes, the actions of graphically allocation and release of GPU resources can be done, which enabled VMs to dynamically schedule the GPU resources. It can provide the high-performance computing in industries and offer fast and efficient GPU resource capability with less complex O&M.
RDM (Raw Device Mapping)
H3C CAS can support mapping between LUN in SAN (FC or iSCSI) and VM. VM can access raw device and the VM data can be stored in LUN directly when building cluster file systems.
Distributed dual-stack firewall
H3C CAS can support the addresses of both IPv4 and IPv6. When the manager need to create VMs, the CAS can customize the policies of vFW in the process of selecting the type of address according to the requirements. The distributed vFW can move the security boundary of data center to the virtual switch layer. The FW based on the vNIC can offer not only different security policies for different vNICs, but also the balance between the performance and flexibility. The security policy will stay with VM when it migrates between nodes.
