Again, the purpose of this series of articles is to strengthen operational management capabilities, i.e. not deployment or general configuration, which requires some basic theoretical knowledge. If you have friends who need to understand the deployment of exchange or basic operations, you can refer to other resources, or see my previous Exchange series articles.This article will learn about the storage prin

Guide Most modern Unix-like operating systems provide a centralized package management mechanism to help users search, install, and manage software. Software is usually stored in the form of "package" in the warehouse "repository", the use and management of the package is called package management. The basic components of a Linux package typically include: S

migrated dynamically. The responsibility for metadata management is also distributed across different nodes. Most clustered file systems use centralized metadata management. Because centralized management is simple and easy to maintain, it can provide more satisfying performance in certain operation frequency. The disadvantage is a single failure point problem,

SCVMM R2 Operations Management eight: adding trusted Hyper-V hosts and clustersWhen SCVMM is created, we need to add the Hyper-V host to SCVMM to facilitate our management.In this experiment, we'll show you how to add an existing Hyper-V host and a Hyper-V host cluster to VMM:There are several main types of hosts that are added to the cluster:1. A Windows Server computer or a Windows Server failover cluster

The following articles mainly describe the Distributed Management of DB2 9. In this column, we will explain the actual operation steps for performing automatic maintenance, it also describes how to use the utility to throttle if maintenance operations need to be performed when the DB2 database is processing the workload. Preface The adaptive utility of DB2 9's throttling system enables maintenance during

File management is an important part of the operating system, and file manipulation is a means of file management for users when they write applications. There are currently many file systems. In the operating systems we've used from DOS, windows3.x, Windows95, WindowsNT, Windows2000, we've used file systems like fat, FAT32, and NTFS that we're very familiar with. These file systems are implemented in diff
