Falconstor CDP in the Disaster recovery backup topology, what role does the database play ...

Previously did not understand the role of Falconstor CDP, always understand the same image database. When you see the following support topology it is only beginning to doubt the relationship between the Falconstor CDP and the database. So, holding the tangled thought of the day, and finally to help my teacher, he gave me the following explanations:

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/4A/07/wKiom1QhcdWg8LnRACO70leYi_0830.jpg "title=" Img_ 20140923_205350.jpg "alt=" Wkiom1qhcdwg8lnraco70leyi_0830.jpg "/>

One, such as Falconstor CDP (Fei Kang), EMC, NetApp, etc. can be understood as disk cabinets + data protection,

1, it mainly solves the host's reliability, the performance, the cluster Chi Pan creates the storage pool.

2. Creating storage virtualization through Falconstor CDP is the integration of multi-physical devices (such as RAIDS, Jobds) running under different interface protocols (such as SCSI, ISCSI, Fibre Channel, or InfiniBand) into the storage pool.

3. The app running on the host is connected to the enclosure via FC, FCOE and iSCSI channels to ensure the reliability, performance and cluster storage of the host data.

4, about the cluster, you can see that CDP plays a role in the coordination of disk, database, host. Multiple hosts access a common disk.

Second, the Linux dynamic Disk (LVM) can be put together to understand, in the Linux system to create a different disk partition, and then, through pvcreate to create dynamic disks, vgcreate and lvcreate create dynamic partitions, Assign these vg to the user or create the mount point.

Third, now can not put Falconstor CDP and database on a level to understand, the database is the application software, is the data to organize, to ensure the order of data, and Falconstor CDP is about the disk cabinet data storage base, to ensure that the data in the physical layer and the region, Offsite data security.

After some of the teacher's explanation I do not regard the function of Falconstor and database as the same, here, also put their own understanding record down.
