    jewelry wholesalers uk The disk array can be divided into three categories: SAN, DAS, NAS. Their common feature RAID.
    Tan is more common in data centers. It uses a large number of disks and high -speed cache disk arrays to provide large -capacity storage space for data center servers.
    DAS, providing storage space expansion for a server (less disk tank with a server has fewer disk slots).
    nas, no server, the client in the office area can be accessed directly. NAS of different brands has different functions, and there are also differences between desktop and data center -level.
    The server is a device accessed by the client, which can build different systems, such as building an email server called an email system. Web server, application server, etc. Of course, there are file storage server you need.
    It you can choose: 1. Large -capacity NAS device,
    2. You can also select the capacity of the server height SAN/DAS (80TB after RAID) to establish a storage file server.
    raid, it means array. It is divided into multiple levels, common is RAID0, 1,5,10,50,60 and so on.
    . Example 1: We can use 4 10TB of hard disks to do RAID1 and get a virtual disk with a capacity of 20TB. Among them, 2 hard disk hard disks work normally. The virtual disk of virtual 20TB capacity has no effect.
    Example 2: We can use 4 10TB of hard disks to make RAID0 and get a virtual disk with a 40TB capacity. 4 hard disks are connected together. But it should not be a hard disk. The whole virtual disk is lost.
    The on the same reason, there are RAID10, there are mirror backup, and the speed doubles. Capacity 20TB. Other RAID levels are checked by themselves.
