 My name is Fui Cheng, I'm from PingTab. And today I want to talk about the local volumesthetic provision. So this is the type of the local percentage volume, and it is the local storage resource, it's bound to the node like the SCC and SFC. It can provide the higher throughput and the HEIF. And it can only have the local access, and when there is a more function, it has no access. Because for the local storage, it has two types of scenarios, and one is TIDB and ETCB. Another is the local cache, and it can tolerate the data loss. The local storage in the Kubernetes, 1.14, it is already available, and you're welcome to use it. And you can use PVC to go to the access. And how to do the provision of the local PV. It has the static local volumes and the dynamic. And the dynamic is now on the development. So today I want to talk about the local volume provision. So this is the provisioner's address of this project, and you are most welcome to participate in the development. So you can have the local volume and the Kubernetes, and if it is not used, it will be recycled, and the other program can work on it automatically. And also, it has two steps. One is to have the local volumes on the nodes to be configured, and the second is to configure and deploy the local volume provisioner. And this is a simple flow chart. The configuration of the local PVs has several typical steps. And for the faster product, faster equipment, we can link it to the target, and the catalog is the provisioner connected to the local machines. And also, it can be shared with the local PVs, with the monocled catalog. And then you will have the block volumes to link the block devices into the discovery dictionary. And also, you can have the file system and the volumes and mount the entire file system into the discovery dictionary. And here in this project, we have the hem, and it is simple. It can have the digital clone and to have the manifest YAML files by using the hem with your customized values and edit the values file with your dictionary and storage class, and then do the deploy and follow this link to get more information. And here it is the best practices of the local PV. The path of the local PV is the unique identifier of the local storage on the node. It is recommended to utilize the UUID of the device to generate the path. And for the IO isolation, a whole disk per volume is recommended. It is very hard to schedule IOPS in the deterministic behavior to the memory and the CPU. So for the capacity isolation, a separate as a partition per volume is also recommended. And also you can go to the different divisions and to do the isolation on the file system, and this is a recommended way. Okay, thank you.
