The company uses NetApp FS8020 R6 as a test environment for NFS storage. There's a chance to measure OpenStack's cinder and NetApp storage integration.Description1.OpenStack using NetApp Storage to mount NFS files directly without any problems, production has been using a more stable test iops in 160-220m/s.2. Cinder with OpenStack cannot be used directly like a

The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile

Here are some specific changes:* MySQL server uses the specified user account, not the root MySQL admin account. This account and password will be exposed to every cloud node, even with certificate-based authentication, so all nodes need access to the database server.* In the MySQL configuration file, restrict access to the server,
