Building efficient, intelligent, and open telecom clouds

TECS Cloud OS Introduction

TECS Cloud OS provides users with NFVI cloud resource pool, to virtualize computing, storage and network resource and implement virtualized management, so as to build cloud data centers rapidly. TECS Cloud OS implements all-round enhancements on the basis of open source OpenStack, KVM, OVS and other projects. Thus, its performance, reliability and security address carrier-grade quality, fully meeting cloudified deployment demands of telecom networks. TECS Cloud OS consists of TECS Compute, TECS Storage, TECS Network and TECS OpenStack.

TECS Compute, based on KVM, provides complete CPU virtualization, memory virtualization and I/O device virtualization capabilities, and supports container to provide lightweight virtualization technology.

TECS Storage shields the difference of storage hardware, to provide cloudified storage for users.

TECS Network, based on OpenVSwitch, provides user-state pure software virtual switch capabilities, lighweight SDN controller and smart iNIC, while also providing high-performance virtual edge router capabilities.

TECS OpenStck, based on open source OpenStack, implements centralized dispatching and management for virtualized infrastructures.

Major Function

  • Enhancements on Virtual Machine

    1. Performance  Enhancements: a. Improving operation performance: Supports to bind the vCPU of VM with the CPU of physical host; supports automatically allocating the vCPU and memory of VM from one NUMA node; the memory of VM supports huge page technology; b. Improving network performance: Supports SR-IOV technology and DVS distributed router; supports multiqueue technology; supports SR-IOV and DVS sharing a physical NIC; c.Improving real-time performance: Supports VM mounting bare disk directly, improving I/O performance effectively; supports real-time OS and real-time VM. 
    2. Deployment Optimization: Supports all kinds of VM deployment policies, such as affinity group per host or host collection (VMs in the group are deployed in the same physical node), anti-affinity group ((VMs in the group are deployed in different  physical nodes), soft affinity group (affinity deployment is preferred; if resource is insufficient, it supports free deployment), VM occupying CPU exclusively, VM occupying NUMA exclusively, VM appointing node/NUMA, and VM deployed in centralization/distribution.
    3. Dynamic Adjustment: Supports hot swap of disk, NIC, USB devices and VM, online/offline migration of storage, and specification/hard disk change of VM, to meet real-time resource requirements of service VMs.
    4. QoS Function: Implements flexible quality control for VM’s CPU, IO, network bandwidth and so on, achieving controllable VM computing capability, and ensuring VMs with different service requirements getting the most suitable computing performance, so as to achieve optimal reuse of resources and reduce cost.
  • High-Performance Network

    1. Support for 25G/40G NIC: Supports virtual switch connecting 25G/40G physical NIC, and supports to use the SR-IOV function of 25G/40G NIC; Supports virtual switch and SR-IOV function sharing 25G/40G NIC, that is, one physical NIC supports both virtual switch and SR-IOV function, and the VM can mix the two kinds of NICs as needed.
    2. IPv4/IPv6 Dual Stack: Supports the management plane using IPv4 or IPv6, while the service plane using the both.
    3. Hardware Acceleration Management: Supports managing and using acceleration hardware (SmartNIC, QAT encryption and decryption card, GPU passthrough, vGPU, etc.), to improve service performance.
  • Special for Edge DC

    1. Lightweight Deployment: Supports lightweight OpenStack system and OpenStack remote deployment.
    2. Real Time: Supports high precision clock, to meet the requirement of access side.
    3. High Reliability: Supporting converged deployment of computing and storage, to meet the storage reliability requirement of edge.
  • Convenient O&M

    1. All-Round KPI Display: Provides 500+ multilevel indexes of the wholes system, host and VM, and supports self-defined report panel to achieve customized report.
    2. DPM and DRS: Supports Dynamic Power Management (DPM) function to reduce the energy consumption of data center by dynamically adjusting the power-on/off state of the node in combination with hot migration function; supports Dynamic Resource Scheduling (DRS) function to guarantee each VM getting required resource in time by dynamically adjusting the load state of each physical node and balancing the load of the whole cluster.
    3. Unified Deployment of VM/Bare Metal: Support to treat bare metal as special VM to manage and deploy.
    4. Management of Heterogeneous Resource Pools: Supports to control resource pools such as VMware and H3C by introducing them into the management system of OpenStack, to provide relevant OpenStack functions for users.
  • Efficient Deployment

    1. Automated installation and Deployment: Provides navigational automated deployment tool Daisy which automatically installs the TECS cloud OS, rapidly deploys large-scale clusters, and supports plug-and-play host.
    2. Visual Configuration: Supports to configure OS and OpenStack rapidly through the interface.
    3. Upgrade and Rollback: Support online/offline upgrade and rollback of cloud OS software; for online upgrade/rollback, it is not needed to power off the VM, and VM can run normally.
  • High Reliability

    1. Highly-Available VM: Supports watchdog monitoring mechanism to detect exceptional VM in time and recover the VM through resetting; supports local self-healing and remote rebirth of VM, so that VM can automatically recover from its own failure or physical node failure; supports multipath storage, to guarantee storage reliability; supports inspection and recovery of cloud disk read-only, preventing storage link broken from leading to cloud disk read-only; Supports inspecting the physical network and carrying out VM rebirth according to failure state, guaranteeing VM operation; supports disaster recovery server which can recover VM quickly when most of hosts power down.
    2. Multiple Kinds of Backup Recovery Mechanisms: Provides multiple kinds of backup mechanisms such as VM backup recovery based on snapshot/file system and local/remote backup recovery based on disk array storage, meeting various requirements of different scenarios.
    3. Disaster Recovery System: Supports distributed disaster recovery management system in 1+1/N+1 mode, and provides disaster recovery function of infrastructure layer, to improve system-level reliability.
  • High Security

    1. OS Security: Implements simplification and security enforcement on the OS layer.
    2. Data Security: Supports image signature and storage encryption; Supports cleaning contents of VM memory and cloud disk when deleting the VM and cloud disk; Supports data encryption of NTP and database.
    3. Account Security: VM supports SeLinux and VNC login password protection; Supports unified account management, authentication management and network access management, achieving unified secure access portal (https); Supports SSO single point login.
    4. Fully meets security requirements of GDPR and DPA.
