Storage Area Network (SAN) may be a technology that permits information storage within the network. All the files and applications are kept domestically inside the drives in order that data transfer takes place between servers and storage devices.
What are the layers of SAN?
Supporting the storage of various components, there are 3 layers in storage area networks. Those are the host layer, material layer and storage layer. The storage devices utilized in this network aren’t connected to the servers directly. Instead a switch is used. The network includes devices corresponding to fiber optic cables, servers and switches.
Though San Storage has become a pretty choice for companies, it isn’t flawless. Unlike different information storage solutions, SAN comes with sure limitations. Before deploying SAN, organizations should fastidiously weigh the execs and cons.
During this article, i’m planning to tell you concerning five blessings and drawbacks of SAN | Drawbacks & edges of SAN.
The pros and cons of exploitation SAN Storage:
Advantages of SAN Storage:
1. Speed:
As SAN includes fiber optics technology, it offers an amazing quantity of speed transfer rates. it’s attainable to realize a speed of over 5Gbps exploitation SAN. notwithstanding your device or the network tends to perform slow, the speed may be simply augmented with the utilization of SAN.
2. Security:
Numerous varieties of security measures are out there on SAN that ensures that your information is secure. On default, the algorithms of SAN are written in a thanks to shield each piece of knowledge kept in it. For example, sure restrictions may be placed on storage such that solely licensed users will be ready to access it. there’s very less likelihood of data thievery happening in SAN.
3. Responsibility:
SAN comes with integral redundancy that creates sure of continuous network operations. Even just in case a server or a switch fails, the traffic will be rerouted to avoid failures.
4. Quantifiability:
SAN additionally offers abundant larger scalability in step with the business needs. If there’s additional storage needs, the users will increase the drives accordingly. This suggests that SAN permits upgrading their infrastructure whenever necessary while not interruptions.
5. Information Backup:
For the method of backing up data, SAN follows a centralized approach. As a result, it needs terribly less time for backing up. exploitation this kind of approach, users will simply backup information mechanically yet as instantly. And notwithstanding there’s a necessity to backup data from multiple locations it’s created attainable employing a single server.
Disadvantages of SAN:
1. Price:
Getting and maintaining an enclosure Network requires a vital quantity of cost. This is often primarily because of the actual fact that fiber technology is being used. Hence, it is particularly popular among organizations of large scale. And SAN takes it slow to point out their impact. Therefore, organizations should be willing to the initial cost.
2. Maintenance:
Not all the time SAN are going to be a helpful option. SAN is intended to manage a great deal of high-priced servers. Maintaining a few servers with the utilization of SAN is a supernumerary expense. During this case, the users may take into account different code solutions. Or else, simply manage the servers themselves.
3. Privacy:
Though SAN implements right security measures, still there’s a break of knowledge leakage. An enclosure Network is employed in a very shared environment. Meaning, a typical device and servers are utilized by the connected computers. If a knowledge happens to leak from one in every of the computers, it may impact the others.
4. Effectiveness:
Notwithstanding organizations are able to settle for the high initial prices of SAN, still it takes it slow to point out its effectiveness. It takes a longer amount of your time to impact a business. Particularly, for services corresponding to period and disaster recovery. Therefore, SAN may be a poor choice, if your business must expertise immediate results.
5. Quality:
SAN is complicated in nature for numerous reasons. One such is the usage of refined storage devices. Hence, it desires maintenance and support to be done by the IT professionals that may additional increase the expenditure of the enclosure Network. This is often one of the explanations why organizations refrain from using SAN.
