vStack HCP Architecture
Three traditionally disparate components are united into a single software-defined solution. The platform creates a single cluster space based on servers that perform 3 functions simultaneously:
SDS or Software Defined Storage
Data Storage Layer
SDN or Software Defined Networking
Network
SDC or Software Defined Computing
Computing resources
IT infrastructure is managed from a single control panel. This allows for quick response to incidents and simplifies the work of administrators.
Technology stack
A software-defined network layer in which the control layer is separated from the data devices and implemented programmatically. Its purpose is to separate the management and processing of network data to create a programmable infrastructure.
The vStack SDN has three ways to provision virtualized networks:
- VLAN;
- VXLAN;
- GENEVE.
Each virtual network instance is based on a distributed switch, has its own MTU and supports jumbo frames, TSO/GSO, TCP MSS clamping and path mtu discovery.
Benefits of vStack SDN:
- Flexible management;
- Customizable infrastructure;
- Security, the ability to
- Isolate compromised devices and create zones for buildings with different levels of security;
- Security, the ability
- High throughput from 22 Mps;
- Support for heterogeneous networks out-of-the-box
A computing layer consisting of dynamically pooled software-defined computing resources.
A virtual machine consists of vCPUs, RAM, virtual network ports, and disk devices. The lightweight nature of vStack reduces CPU Overhead (the performance of a virtualized server compared to a physical server) to minimal values. The vStack SDC is effective in CPU overcommit environments, with cost efficiency in the SDC layer as high as 900%.
Comfortable platform operation in the vStack SDC layer is supported:
- Autonomous CPU overcommit mechanism;
- Limit vCPU resources in real time;
- The ability to create VMs with flexible customization;
- Capability to customize guest OS;
- Limit real-time performance;
- Ability to create snapshots of the VM configuration;
A storage layer that provides data storage with redundancy and transactional integrity with automatic data recovery capabilities.
The vStack SDS is based on a file system. The layer consists of pools that include each node’s disks. At any given time, a pool is running on a specific node in the cluster. Redundancy allows for redundancy. If one node fails, it will be excluded from the cluster and the pools will lose one disk. The pool from the failed node and all VMs on it will be available on another node due to the emergency switchover procedure, which is performed automatically.
With SDS you can:
- Create storage pools with cluster redundancy;
- Provide VM disks to the SDC layer;
- Perform compression and reduplication;
- Maintain data integrity;
- Create clones and snapshots;
- Maintain data self-healing and transactional integrity;
HCI infrastructure layer management component. This is a service VM that contains software for storing and modifying system state, component performance information, and system state.
The task of vStack Management is to manage the infrastructure and its components using web interface and APIs, consistent storage of infrastructure object layer data and storage of component performance information.
Software and Hardware Interaction Layer. This is a set of interconnected software for managing hardware resources of the vStack platform. This layer can also be used to provide standardized primitives for application programs.
The vStack OS is required to enable software and hardware utilization.
