Top ten factors to consider when migrating DAS and

Ten factors should be considered when migrating DAS and NAS to San

storage area networks are essentially related to large enterprises, but they are also becoming more and more popular in small and medium-sized enterprises if the rated voltage of the equipment does not meet the voltage standard. Despite their high cost and complexity, a large number of small and medium-sized enterprises have found that San can meet their storage needs. But the storage area network is not suitable for every small and medium-sized enterprise

there are 10 factors that need to be considered when using storage area networks in the company, or when migrating from direct attached storage (DAS) or network attached storage (NAS) to San

file access speed decreases

if your LAN cannot meet the requirements of the system, the speed of file access will decrease. San can not only reduce the burden of LAN, but also reduce power noise to process storage operations faster, because San is optimized for storage

NAS devices are becoming more and more difficult to manage

Simple NAS devices are a fast, easy and cheap way to expand storage. But they are designed as independent equipment and cannot be well scaled up. If you have a lot of NAS, you will find storage management more and more difficult. Some of their increasingly difficult performances include that you need to do the same management work 23 times on different NAS systems, and you need to manually migrate files to different network attached storage (NAS) devices to balance the load

the growth of storage demand exceeds the expectation

storage will grow, but if the growth of storage is very fast and exceeds your plan, you need storage similar to San to ensure that storage is under control. San not only has a management company that can handle a large amount of storage, its load balancing function can also allow increased storage usage

network blocking affects the overall system, so its material requirements are very high performance

the main factor affecting the accuracy of moving on the network is the system error. The obvious impact of a large number of files is the reduction of file access speed. The less obvious consequence is that everything on the network, not only file access, will be reduced, and in worse cases, the network will become unstable

storage management takes up too much time

with the increase of storage devices on the LAN, the management time is also increasing. In addition to managing a single storage device, it also needs to be adjusted to balance the load, make the best use of it, and get the best performance. As the name suggests, San can give you a centralized point to manage storage, thus saving time and energy

centralized it

re architecting it is the best time to consider migrating to a storage area network (SAN). Using it consolidation, server and storage virtualization, enterprises can redesign their information architecture to reflect changes in business strategies, take advantage of new technologies, reduce costs, or gain competitive advantage. Re architecting the data architecture, carefully consider the best time to migrate to the storage area network. San is a natural partner of virtualized servers, virtualized storage and other modern storage technologies

the growth of data backup exceeds the space limit

san technology can expand the backup space by accelerating the file transfer in backup. In fact, a well-designed storage area network can significantly reduce the backup space, which can be backed up by allowing you to use LAN heavily with little impact on performance

there are a lot of large documents on the network

large documents need faster network, especially for work such as video editing and arresting. It is no coincidence that video editing is one of the first places to use San. You can adjust the storage area network (SAN) according to the size of documents that need to be processed and stored, and use LAN for daily use such as mail

need to expand the network

san naturally has better scalability than other methods. You can start small, and then add switches and storage arrays to expand the San to a higher scale than the needs of small and medium-sized enterprises. A well-designed San can scale to any size that small and medium-sized enterprises may need

a large amount of data needs to be quickly migrated to different locations.

a multi-source, multi-target topology can benefit from the switch oriented architecture of San. According to the way information flows into the business, you can segment the system so that users are close to the transmission server in the topology, or you can structure the network to maximize the access between the server and users on the whole network. And if you find that the initial settings are not optimized enough, you can redesign the network without adding additional devices

you don't need to show all these signs. If one of them has appeared, then other cheap repair measures should be used for storage. (for example, if the file access speed decreases, the first step is to analyze the file operation, check the bottleneck, and adjust the file system according to the problems you find.) If several of these signs appear on your system, you should seriously consider purchasing a storage area network (SAN). (end)
