storage is useful for storing important company data that can be changed and accessed again when needed. Backup is useful for making copies of files needed by the company if the main storage area is damaged or affected by a disaster
In general, some companies use three types of server storage, namely: Network Attached Storage (NAS), Direct Attached Storage (DAS), and Network Place Storage (SAN). Each storage server has its own advantages:
This type of server is often referred to as a hybrid option. Servers generally use dedicated servers or special equipment that can provide services for storage arrays. In most cases, storage will generally be split between multiple clients simultaneously across all existing Ethernet networks. These NAS servers generally use enhanced file transfer power. Compared to DAS servers, the start-up cost of NAS storage is generally lower.
Of course, this makes NAS storage a perfect fit for small and medium-sized enterprises. You can share files using various procedures, such as UNIX, CIF, and NFS. Typically, a NAS uses a target ISCI storage array that can be split between all existing networks. Networks can be configured to increase network throughput.
Direct-Attached Storage (DAS) refers to a digital storage mechanism that is connected directly to a server or workstation without a storage network as a mediator. In other words, it is storage that is directly connected or point-to-point to a server or computer.
DAS storage can only be reached directly from the host that installed the DAS. DAS excludes network hardware and associated operating environments to promote resource sharing independently of storage. If you use external storage connected directly to an external stream, it falls under the “direct-attached storage” group and now uses a SCSI card.
This technology is suitable for various situations that require fast access to the disk mechanism because the DAS transfer speed between the server and the hard disk is very fast. Therefore, many programs are usually really compatible with this technology. DAS is also suitable for small networks. In terms of costs and the ability to store media or hard drives, this technology is still cheaper than other technologies.
Storage with this type of SAN is the most suitable solution for medium to large businesses. Some of the infrastructure required by a SAN are a SAN Switch, HBA, fiber cable, and disk controller. One of the advantages of this storage is its ability to share server storage to several existing servers. This allows you to compose the capabilities of the storage you need.
But the performance is better than the 2 servers described above, this SAN server has a more expensive price. In addition, these SANs are inherently more complex to administer. But everything will be worth it and fit, plus indeed this server or storage is prioritized for businesses or businesses with the upper-middle class.
