[TiDB Usage Environment] Production Environment, Testing

[TiDB Version] v5.1.0

[Encountered Problem: Phenomenon and Impact] Currently, the server hard disk configuration purchased by the company is relatively low, with IOPS testing only in the thousands (see detailed images below). To provide better IOPS, we plan to standardize the disk model. We often see that the IOPS test of server disks purchased by enterprises can reach 100k~200k. We hope to collect relevant server configuration information (disk information such as interface and protocol) for procurement reference. I have also searched for relevant disk interface protocol information, but there is no actual environment to test and verify. Therefore, I would like to see the server configuration and IOPS test results in other industries.

Reference Value 1: Non-NVMe SSD fdatasync/s is about 5~8K/s

Reference Value 2: Early NVMe fdatasync/s is about 20~50K/s

Reference Value 3: Current mature PCIe 3 NVMe fdatasync/s is about 200~500K/s

Refer to this, it’s easy to judge with parameters.

I have these reference values. Now, the main task is to set the procurement standards for hard drives. Our purchase order is very simple, and I need to specify detailed parameters, such as M2 NVMe SSD, etc.

Just compare the brands and choose accordingly. Each company has its own scenarios. Some are hyper-converged, some are virtualized SAN, and some directly interface with physical disks. It’s hard to make a recommendation :rofl:

The simplest way is to ask your company’s supplier to provide you with alternative products based on these parameters.
