Selecting a Network for Turbo CFS

Last updated: 2024-01-22 22:15:48
    CFS Turbo is Tencent Cloud's high-performance parallel file system. Compared with traditional ‍general CFS, it supports CCN and VPC networks ‍(with respective pros and cons) on the client and server. This document describes the two network types to help you select a more suitable one for your business. If you use CCN, we recommend you create Turbo file systems based on CCN; otherwise, you can select VPC for easier use, if applicable.



    Specified CIDR blocks are assigned to Turbo file systems, and CCN capabilities are leveraged to connect the VPC and storage server network, implementing the interaction between compute instances and storage.
    CIDR block planning is separately conducted for storage systems for more efficient and convenient management of security groups.
    Turbo CFS has its own CIDR block to reserve sufficient IPs for future scaling without limits.
    Turbo CFS can be accessed more easily across VPCs.
    IPs of the existing VPC are not occupied.
    CCN is required for network connection. If CCN is not used, a new component needs to be introduced, which is quite complicated.

    Best practices

    You can select 10/11/30/172/192 CIDR blocks to create a CCN instance. It is recommended that Turbo CFS be assigned 11/30 blocks, which are server-side blocks and do not occupy business IPs.



    IPs are mapped to the existing VPC on the storage server for mount and access.
    It is the easiest to use and is similar to general CFS.
    No new components need to be introduced in this simple solution.
    During large scaling, subnet IPs may be insufficient.
    VPC IPs will be occupied, and the storage is bound to the VPC, which hinders network isolation.
