【TiDB Environment】Production
【TiDB Version】6.1.0
【Encountered Issue】

The issues are as follows:

  1. Currently, my TiDB cluster is deployed using SAS disks (configured with RAID10). Should I adjust the IO scheduler strategy?
  2. I have created an installation plan myself. Please review it to see if it is reasonable.
    1. pd + tidb Virtual Machine 16 cores, 32GB memory, 800GB-SAS disk, ext4 file system 3 units
    1. tikv Physical Machine 40 cores, 64GB memory, 1TB-SAS disk, ext4 file system 3 units
    1. tiflash Physical Machine 40 cores, 64GB memory, 1TB-SAS disk, ext4 file system 2 units

【Reproduction Path】What operations were performed that led to the issue
【Issue Phenomenon and Impact】

For PD and TiDB, you can use smaller disks but increase the CPU and memory.

Testing or going to production?

Getting ready for production.

What type of business is it, and how much concurrency is expected? The disk performance is too poor. For production, at least a regular SSD is needed. Additionally, version 6.1.1 is the latest and fixes some bugs.

:wink: The plan is still missing a central control machine and a backup machine.

For mixed-type workloads, including both TP and AP tasks, the concurrency is in the hundreds.

Is there any expert who can clarify question 1?

The expert upstairs already gave a suggestion, right? I recommend switching to an SSD.

Can’t get the SSD approved.

Another question, can I use the XFS file system for my PD+TiDB machines?

Support for XFS is available, and it can be deployed and used normally. However, for production environments, safety should be the priority, so it is recommended to use ext4.
