When people refer to security network applications, most of them think of network surveillance cameras. In fact, the composition of the monitoring system is not limited to front-end products. If there is no back-end storage device, the huge image data can only become "clouds." There are 10 technologies related to network storage:
NAS system:
Network-attached storage systems, file storage, and access all need to go through the local area network and also support the addition of extra storage over Fibre Channel or SCSI-based switches.
NAS Gateway:
That is, no disk file server, it uses a SAN storage array to provide extended storage capacity.
SAN architecture:
Multiple servers in the network are connected to a central disk repository consisting of one or more storage arrays, greatly improving system management and data backup.
Cloud storage:
Through the functions of cluster applications, grid technologies, or distributed file systems, a large number of different types of storage devices in the network are brought together through application software and work together to provide external data storage and service access functions.
HBA:
A pluggable card that connects a host computer to a network/storage device and supports multiple storage network protocols.
IP storage:
Using the IP protocol to connect a remote SAN, in a Fibre Channel SAN, the IP protocol is used to send FC frames in IP packets. For non-fibre Channel SANs, the iSCSI protocol is used to convert SCSI data to IP packets.
RAID:
Independent redundant disk arrays require multiple disks to improve performance and fault redundancy.
LANfree backup:
Back up data to a storage array, tape library, or other storage device without going through a LAN or WAN network.
Fibre Channel:
Data requests are transferred from the server to the disk array, and Fibre Channel switches in the SAN are used to connect servers and storage arrays.
Block-level storage:
Block-level access ensures that network users do not have to manage data when reading/copying files from disk, allowing network administrators to specify where data is stored to address performance issues.
