Duplicate data deletion (De-duplication, DDD) is one of the advanced features of networked storage devices, which can effectively reduce the storage space occupied by duplicate data and increase the space utilization of storage devices.
The data de-duplication feature for NetApp filer is called a-sis. When applying the command line in the following example, replace the/vol/vol1 with your own volume name.

Without knowing it, cloud computing has been around for so many years. For the cloud, people are excited from the beginning of their contact with each other, continue to debate, and then fight for public cloud, private cloud, and hybrid cloud, now it's time to pull the cloud and witness "turning the cloud into rain.
From the blind pursuit of the cloud at the beginning to the present, users began to become rational. If they could bring direct benefits, they would be useless. Based on different a

DirectShow is a member of DirectX, it is used for audio and video data collection, multimedia file playback, and other applications. The most basic functional module in DirectShow is filter (each rectangle block in Figure 6 represents a filter). Each filter has at least one pin for receiving or outputting data; filter always provides certain functions (in figure 6, the first

2 queues in the queue Manager can be specified as Cluster shared queues, visible to all queue managers in Cluster, and Cluster shared queues defined in different queue managers automatically implement load balancing for the queue;
3 a master-slave relationship can be specified between broker agents of different queue managers, so that tree-like pub/sub structures can be conveniently implemented in Cluster.

With future upgrades to file system protocols, such as NFS (including concurrent NFS, or PNFS), will NFS potentially replace many of the existing proprietary file systems?
Let's take digitalfilm tree for example, a company in Hollywood that provides post-processing and virtual effects services for the entertainment industry. The company employs products that include Apple Xsan, HP storageworks arrays, QLogic switches, and other storage vendors. They also use a hybrid operating system environmen
The file modification time on the NFS file system displays the problem of Solaris + NetApp storage. the user's home directory is placed on NetApp and mounted to the local through autofs. You can use ls-l to view the touch file in your home directory. the mtime (modifytime) column only displays the year, month, and day ,... the file modification time on the NFS file system displays the problem of Solaris +
Next we will mainly explain the content of NFSv4. What are the features of the fourth NFS version? Let's take a look at it. NFS is composed of server software-for example, software running on NetApp storage-client software requiring access to network storage and running on the host. proper operations require that the two ends of the connection, that is, the client and the server are mature and have been correctly implemented. although
