. One of the functions of a hard link is to allow a file to have multiple valid pathname (multiple portals) so that users can establish a hard link to important files to prevent "accidental deletion" of the source data (many hardware storage, such as NetApp) in the storage of the snapshot feature applied this principle, add a snapshot more than a hard link). Why does a file create a hard link that prevents the data from being mistakenly deleted?Becaus

1 Hard Link conceptsA hard link is a link through an index node (inode) in a Linux (EXT2,EXT3) file system in which a file saved in a disk partition is assigned a number, which is called the Index node number (inode index) or inode. That is, the number of the file in the system.In a Linux file system, it is normal and permissible for multiple filenames to point to the same index node (Inode). A file of this kind is called a hard link, one of the functions of a hard link is to allow a file to hav

cloned databases for development or testing (some clone databases are still writable). Windocks is an extensible system that supports the management process involved in creating snapshots and cloning processes. Support for increased snapshots and clones is provided by the Administrator, who can choose to enable the Privilege command in the Windocks node.cfg file. In the example below we use a simple "copy" command to show the process. Dockerfile can define a SQL Ser

2003, the whole system in the construction and planning has done quite a lot of attempts and exploration. The picture below is Taobao 2007 before the image storage system. Taobao has been using the commercial storage system before, applying NetApp's file storage System. With Taobao's picture files growing at a rate of twice times a year (3 times times the size of the original), Taobao's back-end NetApp storage systems migrated from low-end to high-en

Primary file System storage optimization (that is, to cram more data into the same space) continues to grow in popularity. The challenge here is that duplicate data deletion from primary storage is not without rules. You can't delete this duplicate data, and you can't delete the duplicate data, you have to recognize the impact of the removal of duplicate data on the performance of the device. EMC has announced the ability to remove duplicate data on its own Celerra platform.

is that there is a lot of development value in this area. Government agencies have been the main investors in storage it vendors, and many industry reports have shown that the trend towards architecture optimization, content security, and Web 2.0 network development is proving that future government storage needs will become stronger. 6th place: Medical filing.

mirrored 146GB 10K to SAS drives, and shared storage is NetApp fas3020c, with software iSCSI connectivity, The MPIO is used in the design of the storage network. The VMFS LUNs for shared storage are experiment-specific, with no other load on it, and the blade server is only an experimental VM, with no additional load. The reason why such a specific description of experimental equipment, is to express a clear meaning: server, network, storage performa

VMware connects to shared storage in three different ways, San,ip sans (that is, iSCSI) and Nas (NFS). This article is not about the difference between the 3 and the SAN and NAS, please go to Google. Second, this article does not look at FC Sans, if your environment already has a SAN that supports MPIO and has enough storage space, try to make the most of it. Because many articles point out that Nas/nfs is an ideal medium for low I/O demand workloads, fiber optics is ideal for high demand workl

NFS storage for ESX typically configures backup links. Automatically switch to the backup link when the primary link fails, which is called failover. Q: When will the failover be launched? A: When a storage link fails to be found. Q: How can I tell if a storage link is interrupted? A: I can't find my heartbeat. Q: What happened to the heartbeat? How can I find a heartbeat? A: Normally the ESX host initiates a heartbeat to the store at regular intervals (heartbeatfrequency), and each heartbea

The concept of linksin Linux systems, links can be divided into two types: one called hard link, and the other is called soft link or symbolic link (symbolic link ). With the default without parameters, the link created by the Execute ln command is a hard link. Hard Linksa hard link is a link through an index node. in a Linux file system, files saved in a disk partition will be assigned a number regardless of the type, which is called the Index node number (Inode index) or index . in the In a
