5 What's New in FusionSphere 5.1 Computing Virtualization VM Lifecycle Management (Enhanced) In FusionSphere 5.0, a VM can start only after the BIOS successfully starts. FusionSphere 5.1 eliminates this restriction and allows a VM to start even when the BIOS has not waited, thereby reducing VM startup time by 5 seconds. Shared Nothing VM Live Migration (Enhanced) The VM migration enhancements allow you to: Change both the host and data store of a VM with snapshots created. Specify the destination disk mode. The destination disk can be in the common, thin provisioning, or thick provisioning lazy zeroed mode and can be in the same or different modes with the source disk. Query the progress of a migration task. Cancel a migration task. VM Cloning FusionSphere supports cloning of either a running or stopped VM when FusionStorage is used. Support for UEFI Firmware on VMs FusionSphere 5.1 supports use of Unified Extensible Firmware Interface (UEFI) firmware on VMs. With this function, you can migrate a system disk larger than 2 TB from a physical server to a VM by setting UEFI boot firmware and the GPT partition. Online CPU and Memory Resource Modification (Enhanced) FusionSphere 5.1 allows you to add CPU and memory resources to or reduce the resources from a running VM. For some OSs, you need to restart the VM for the CPU and memory resource modification operations to take effect. 8

6 What's New in FusionSphere 5.1 Backup and DR Host-based Remote Replication DR (Enhanced) FusionSphere 5.1 enables one-click service switchover between the production and DR sites. VM Backup (Enhanced) FusionSphere 5.1 provides the LAN-free mode backup and file-level data restoration. 9

7 What's New in FusionSphere 5.1 Self-Service Capabilities Self-Service and Self-Maintenance FusionSphere 5.1 enables users to perform common service operations using service catalogs and enables VDC administrators to perform routine operation and maintenance (O&M) on the portal provided for tenants. Out-of-the-Box Service Catalog Featuring out-of-the-box, the service catalog pre-defined in the FusionSphere system enables you to quickly deploy resources and applications based on service requirements. Service Application Approval, Application Form Management, and Custom Approval Procedure FusionSphere 5.1 allows you to view administrator-defined services in service catalogs on the self-service portal. You can select services based on your service requirements and submit service applications. When applying for a service, you can also specify service specifications and the validity period. Tenants and administrators can query application form status and progress and approve service applications. Users can customize the approval procedure based on service requirements. 10

8 What's New in FusionSphere 5.1 FusionSphere SOI Root Cause Analysis FusionSphere 5.1 introduces a new component, FusionSphere SOI, to perform in-depth analysis of performance anomalies, to quickly identify the cause for performance deterioration, and to locate workload that may adversely affect performance. FusionSphere SOI also provides historical information about health status indicators associated with an event and displays the performance change trend in graphics to facilitate fault locating and rectification. Capacity Report FusionSphere 5.1 allows reports to be generated by different granularities to display VM, host, and cluster performance and capacity data and prediction results. A report can contain graphics, tables, and text descriptions. 11

14 Compatible with OSs Intended for Special Application Scenarios FusionCompute control domain VM VM VM VM VM VM Custom PV backend driver PV driver PV driver PV driver PV driver PV driver PV driver FusionCompute Vendors must provide applicable PV drivers to enable FusionCompute to be compatible with a new OS. Huawei is capable of developing applicable PV drivers. In addition to mainstream Windows and Linux OSs, FusionCompute is compatible with the NeoKylin OS. (Certain OSs may need customized drivers.) 17

15 Flexible Management and Optimal Scalability FusionCompute Web Client FusionCompute Web Client VRM nodes for cluster management (active/standby) VM VM VM VM VM VM VM VM VM VM VRM nodes for cluster management (active/standby) VRM nodes for cluster management (active/standby) CNA CNA CNA CNA CNA VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM SAN Local storage CNA SAN CNA CNA CNA CNA Local storage CNA CNA Local storage CNA CNA SAN CNA Logical cluster 1 Technical features & benefits Logical cluster 2 Logical cluster 10 Logical cluster 11 Logical cluster 20 Logical cluster 21 Each logical cluster supports up to 128 physical servers, which is the industry best practice. FusionSphere reduces the number of redundant physical servers and is suitable for deploying large-scale service clusters requiring high performance. Each logical cluster supports up to 3,000 VMs, which makes FusionSphere applicable to scenarios requiring a large number of VMs that do not have high performance requirements, such as in desktop cloud scenarios. VRM nodes can be deployed in active/standby mode on both physical servers and VMs to ensure system availability. Up to 16 VRM nodes can be cascaded. Cascaded VRM nodes support up to 4,096 physical servers and 80,000 VMs, which is the industry best practice. 18

16 GPU Virtualization VM 1 VM 2 VM 3 vgpu driver vgpu driver vgpu driver vcpu support Huawei UVP vgpu vgpu GPU vgpu Implementation GPU virtualization is to create multiple vgpus on a physical GPU that supports virtualization. vgpus can be attached to each VM to allow the VM to directly access hardware resources of the physical GPU. Technical features Provides GPU virtualization based on NVIDIA GRID and improves user experience on graphics-intensive applications. Supports vgpu management and scheduling to balance load of physical GPUs. Supports the OpenGL and DiretX multimedia application programming interfaces (APIs). Supports AERO visual effects, multiple monitors, and hardware-based performance acceleration for DXVA videos. Application scenarios VMs running engineering drawing software, such as Pro/ENGINEER, CATIA, and AutoCAD, and graphics rendering software, 3D games, and GIS applications Industrial design, multimedia editing, energy industry, financial service and trade, medical imaging, and education industry Benefits Improves user experience on graphics-intensive applications in a virtual environment. 19

17 Flexible VM Configuration Modification VM Virtual resource pool App FusionCompute Function details vram: Hot and cold add and remove vcpu: Hot and cold add and remove Technical features FusionSphere 5.1 enables you to change the number of vcpus on a VM and its memory size when the VM is running. The changes take effect immediately and do not need the VM to be restarted. For a VM running an OS that does not support vcpu or vram hot add or remove, you must restart the VM to make the modifications take effect. Application scenarios The number of vcpus on a VM and the VM memory size need to be flexibly adjusted based on service requirements. Benefits Flexibly adjust VM configurations based on service requirements. Add vcpus and vram to expand capacity of a VM based on VM QoS requirements. Add VMs to expand capacity of a cluster based on cluster QoS requirements. 20

18 Memory Overcommitment, Improving VM Density by 30% Memory sharing and copy-on-write VM 1 VM 2 VM 3 VM Memory swapping VM Memory ballooning VM 1 VM 2 Idle Memory ballooning Idle Used Physical memory Disk Used Memory sharing: Multiple VMs share the same physical memory block (marked in blue), and the VMs only read data from the memory block. Copy-on-write: When a VM needs to write data to its memory block, another memory block (marked in red) is allocated to the VM to write the data and the mapping between the allocated block and the VM is created. Technical features 21 Memory swapping: The memory data that is not retrieved by the VM for a long time is swapped to a disk, and a mapping between the memory data and the disk is created. When the VM needs to access the memory data again, the memory data is swapped out from the disk back to the memory block. Memory ballooning: The hypervisor uses the memory ballooning mechanism to release the idle memory on a VM and allocate the memory to another VM with high memory usage, thereby improving memory utilization. By leveraging the preceding memory overcommitment techniques, Huawei FusionSphere increases the memory overcommitment ratio by 130%, which makes Huawei overtake its competitors in terms of memory utilization, such as Citrix. Benefits With the same memory resources, the VM density of the FusionSphere platform increases by 130%, which helps to reduce procurement costs on memory components by 30%.

19 NUMA Affinity-based Scheduling Implementation The NUMA topology is presented to VMs to enable the guest OS to allocate resources to applications running on it based on logical NUMA nodes, thereby improving application performance. Technical features Guest NUMA implements NUMA-topology-based optimizations and enables a CPU to preferably use memory resources on one NUMA node. Application scenarios Large-size and high-performance VMs are required. VMs run key applications, such as Oracle and SQL Server databases. Benefits Reduces memory access latency and improves VM access efficiency, thereby improving application performance. 22

21 Thin Provisioning, Cutting Storage Investments VM VM VM VM Common 20 GB FusionCompute Physical storage device Thin provisioned 40 GB 20 GB 20 GB 100 GB Thin provisioned 80 GB 40 GB Virtually allocated: 120 GB Actually allocated: 80 GB Physical space: 100 GB Implementation Thin provisioning operates by allocating disk storage space to users based on the minimum space required by each user at any given time. Only the disk space actually used by a user is allocated to the user, and FusionCompute increases disk space allocated to users with the increase of data on user disks until all disk space requested by the users are allocated to them. Technical features The configured capacity is displayed for VM users. However, the allocated disk space is dynamically adjusted based on actual usage. Disk usage is monitored, and alerts are generated if the allocated disk space is about to become insufficient. Disk space reclamation is supported. Application scenarios Large storage capacity and low IOPS are required. Benefits Improves storage space utilization and lowers storage costs. 24 Page 24

22 Online Virtual Disk Capacity Expansion VM VM VM VM FusionCompute FusionCompute SCSI Implementation This function enables you to expand disk capacity without stopping or restarting the VM. Technical features This function is based on Virtual Hard Disks (VHDs). The newly added virtual disks take effect without requiring the VMs to be restarted. Application scenarios On-demand, scalable disk capacity expansion is required. Benefits This feature avoids unnecessary service interruption and ensures service continuity. 25

23 RDM for SAN Devices VM VM VM VM Implementation Raw device mapping (RDM) provides a mechanism for a VM to have direct access to a LUN on IP SAN or FC SAN devices. RDM enables VMs to identify SCSI disks. FusionCompute Technical features VMs can read data from or write data to physical storage devices through SCSI commands. Supports both IP SAN and FC SAN devices. SCSI SCSI Application scenarios Applications requiring high storage performance, such as Oracle RAC SAN storage device Benefits LUN LUN LUN RDM enables applications requiring high storage performance to be deployed on VMs. 26

27 Auto-Sensing NIC Performance Optimization, Improving Network Processing Efficiency by 30% Item Pre-Optimization (Virtualization Platform) Preoptimization (Virtualization Platform) Post-Optimization (Virtualization Platform) Pre-Optimization (VM) Postoptimization (Virtualization Platform) Post-Optimization (VM) Preoptimization (VM) Postoptimization (VM) Rx (kpps) CPU (%) CPU(% ) Rx(kp ps) Implementation The NIC uses the auto-sensing interruption aggregation technology for receiving network packets. Therefore, the NIC can receive small packets in batches, reduce the number of interrupts, and improve the receive and send speed of 10% of small packets. Technical features Single-thread network packet handling is optimized. The multiple-threads-and-no-lock technology is used to improve the concurrency performance, and the receive and send performance of 30% small packets can be improved. Application scenarios Network games and instant messaging that have large numbers of network packets smaller than 512 bytes and that require low latency Benefits Increases the real-time processing efficiency of small network packets by 30%. 30

28 Support for Trunk Ports by vnics VM VM... vnic 0 vnic 1 vnic 7 Access port vnic 0 Trunk port VLAN 100 VLAN 101 VLAN 107 Virtual switch FusionSphere 3.0 A VM supports up to 8 vnics. Therefore, a maximum of 8 VLANs and 8 subnet gateways are supported. VLAN 100 to VLAN 200 Virtual switch FusionSphere 3.1 vnics support trunk ports so that a vnic can support multiple VLANs. Benefits Because vnics support trunk ports, a vnic can support multiple VLANs for more flexible networking and for more complex service scenarios. 31

29 10GE Gateway for Key Applications and I/O-Demanding Scenarios Control domain VM VM Control domain VM VM Control domain VM VM VIF Bridge VIF Bridge PF driver VF driver VF driver FusionCompute FusionCompute FusionCompute queue queue queue PF... Differences Characteristics Common vnic Domain 0 bridge queue One-time data copy High CPU overhead which adversely affects VM density Smooth VM live migration and snapshot VMDq-enabled NIC Independent VM packet queue One-time address translation implemented by the hypervisor, which consumes little computing resources Little CPU overhead Smooth live migration, snapshot, IP-MAC address binding (VMware cannot provide this function.) SR-IOV-enabled NIC (Enhanced in FusionSphere 5.0) Address translation implemented by the SR- ROV technology The hypervisor does not need to implement address translation, which reduces computation consumption. Little CPU overhead Limitations: Smooth live migration and snapshot features are unavailable (the same as VMware) NIC throughput: 9.1 Gbit/s (TCP) NIC throughput: 9.15 Gbit/s NIC throughput: 9.5 Gbit/s 32

30 Distributed Virtual Switch (DVS) VM 1 VM 2 VM 3 VM 11 VM 12 VM 13 FusionCompute FusionCompute Virtual switch 1 (Web) Virtual switch 2 (App) Server A Server B Implementation Application scenarios Enables the virtualization administrator to configure and maintain physical and virtual ports of the DVSs on multiple hosts. Technical features Enables centralized configuration and management and helps customers understand the network structure. Supports VLAN configuration, layer 2 network security policies, and network bandwidth control. 33 Virtual switching networks of a large number of hosts need to be centrally managed. Benefits Provides more flexible network policy control.

31 Support for IPv6 for the Service Plane IPv4 (external network) Load balancer Switch (L3) External network Switch [L2] Direct network VMs (IPv4/IPv6) IPv6 (external network) Firewall/VPN DHCPv6 Benefits VMs support both IPv4 and IPv6. Each VM NIC can have an independent IPv4 or IPv6 address or have both of them configured. The provided service plane network services, such as security groups, network port binding, network QoS, and VPC external network management, also support both IPv4 and IPv6. The system service plane supports IPv6, which provides more IP addresses than IPv4 and enables more flexible and convenient networking. 34

32 DVS Uplink Port Bonding Server System priority, port priority, and active port LACP PDU LACP PDU LACP PDU Access switch LACP vswitch inic Implementation Implemented based on the standard LACP protocol included in IEEE 802.3ad Technical features Supports manual link aggregation and static LACPbased link aggregation. The static LACP-based link aggregation can only be manually configured. (The system will not automatically create or delete aggregation groups.) The static LACP-based link aggregation detects links through LACP packets and can discover link faults, such as ports in errordisable mode. Application scenarios High server bandwidth and high reliability are required. Benefits Increases server network bandwidth and improves network link reliability. Automatically detects the faults at the link layer and incorrectly connected links and performs link switchover, significantly reducing the network access failure rate. 35

33 Enhanced ARP Attack Defense Capability VM 1 VM 2 VM 3 VM 1 VM 2 VM 3 VM1 VM2 Benefits ARP req ARP rsp Normal condition: If VM 1 wants to communicate with VM 2, the ARP requests of VM 1 broadcasts at layer 2 and the VM 2 IP address is contained in the request. Therefore, only VM 2 responds to the request. ARP attack defense avoids ARP spoofing that uses faked IP or MAC addresses. The ARP attack defense capacity provides protection against a malicious VM from encrypting other VMs' data packets using a fake gateway address, causing network interruptions, or interrupting VM communication at layer 2 by initiating flood attacks. ARP req ARP rsp ARP rsp Man-in-the-middle attack If VM 1 wants to communicate with VM 2 and VM 3 wants to intercept the conversation, then VM 3 sends a fake message to VM 1 and claims to be VM 2. Therefore, VM 1 actually sends data packets to VM 3. Flood attack To initiate a flood attack, VM 3 sends a lot of ARP packets to the system, eventually interrupting the network communication. 36

34 VM Network QoS Control 256 Kbit/s Token 128 Kbit/s Queue Traffic classification Token Bucket FR inic 128 Kbit/s Implementation Network QoS provides traffic shaping and bandwidth priority control for virtual NICs and system ports. Technical features QoS control can be implemented for both inbound and outbound traffic. Traffic shaping can be implemented for outbound traffic based on the token bucket algorithm. Application scenarios High-quality network communication between the network plane and user VM network is required. Benefits QoS control on inbound traffic avoids resource contention and ensures traffic fairness. The burst size and peak bandwidth can be configured to allow a burst when the system has significant idle resources. Traffic shaping avoids packet loss, network jitter, and other adverse impacts on services caused by rate limiting. 37

35 Virtual Service Appliance (VSA) Application Gateway Interface VSA DHCP NAT ACL Router VIF 1 VIF 2... VIF N Technical features Based on trunk ports and the sub-interface mechanism, the VSA supports unlimited number of VLANs. The VSA provides comprehensive services, such as NAT, ACL, routing, DHCP, and load balancing. The VSA supports VXLAN and can function as the VXLAN gateway of a DVS. Benefits vnic 1 vnic 2 vnic 3 vnic 4 Trunk DVS VXLAN interface The VSA can function as a software gateway and provide application services to implement flexible network control and software-defined networking (SDN). 38

37 VM Live Migration (VM Motion) App App FusionCompute Server A FusionCompute Server B App Technical features VM live migration efficiency is improved one-fold by leveraging the memory compression technology. The source and destination hosts involved in live migration can use CPUs of different generations. Application scenarios Short-time service interruption is tolerable and services must be quickly restored, such as lightweight database services and desktop cloud services. VM live migration does not interrupt VM services and is insensible to users. 40

38 VM Cloning Technical features App OS App OS App OS App OS App OS App OS VM cloning is to quickly create a copy of an existing VM. The new VM has the same specifications and storage content as those of the original VM. FusionCompute FusionStorage Application scenarios Quick VM creation is required and VMs to be created need to have the same specifications as existing VMs. FusionSphere allows online and offline VM cloning when VIMS or FusionStorage is used. 41

39 Enhanced VM HA Mechanism App OS OS X App App OS ŸPhysical server A App App App OS OS OS ŸPhysical server B Technical features Fault detection for hosts, virtualization platforms, and VMs is supported. Supports both VM HA and VRM-independent HA. The network plane used for HA heartbeat monitoring can be configured, which helps to lower the network pressure. Multiple fault diagnosis mechanisms are supported to ensure fault diagnosis accuracy and completeness. HA of VMs using shared or local storage is supported. Benefits APP OS APP OS APP OS N hours 3 minutes ŸPhysical server C ŸHA resources (reserved) Physical host VM Significantly reduces the time for fault rectification and service downtime, and ensures service continuity. 42

40 Fault Tolerance (FT) Technical features Switchover takes only a few seconds and has no Transaction service Settlement service Transaction service Settlement service impact on IT services. (Packet loss rate < 1%) FT can be enabled for VMs that has two vcpus. App Real-time data synchronization App (VMware vsphere supports FT for four-vcpu VMs.) Performance loss is between 5% to 30%. FusionCompute FusionCompute X FT (no service interruption) Server A Server A' Application scenarios Systems with high reliability requirements, such as the transaction system and enterprise resource planning (ERP) system 43

41 Dynamic Resource Scheduling (DRS) App App App App App App App App FusionCompute FusionCompute FusionCompute FusionCompute Technical features Automatically balances cluster loads based on the scheduling policies. Provides optimized scheduling algorithms and performs scheduling based on the VM load change trend to avoid VMs from being repeatedly migrated among hosts. Provides the unique scheduling baseline threshold configuration function to avoid unnecessary migration. Allows FusionCompute to be configured so that it does not migrate specific VMs or manually migrates specific VMs. Allows manual migration performed by administrators or automatic periodic migration based on configured policies. Automatic migration can be implemented at specified intervals by day, week, or month. Application scenarios & benefits VM load dramatically changes and VM users have high performance requirements. DRS helps to balance load on hosts to fully utilize host computing resources and improves efficiency of service systems running on VMs. 44

42 Distributed Power Management (DPM) App App App App App App FusionCompute FusionCompute FusionCompute FusionCompute Technical features The system automatically migrates VMs on light-load hosts to other hosts and powers off the light-load hosts based on user-defined DPM policies. If the loads on hosts in the system exceed the configured threshold, the system automatically selects hosts and powers on them to balance the host loads in the cluster. The system can select one or multiple hosts to power on or power off. The system powers on or powers off hosts based on both the DPM and DRS policies to avoid mutual influence. The scheduling policies can be configured at a specified interval by day, week, and month. Application scenarios & benefits VM loads dramatically change and VM users need to reduce power consumption. When hosts are light-load, some VMs on the hosts are migrated to other hosts and idle hosts are powered off to reduce system power consumption. The prerequisite is that each VM must have sufficient resources for running after being migrated. When hosts are overloaded, some hosts are automatically powered on and VMs are migrated to these hosts to ensure VM performance and customer experience. 45
