The hottest way to use NAS gateway correctly

  • Detail

The correct use of NAS related methods

file management has become one of the most difficult problems for major enterprises. How should documents be kept? Which level of disk is suitable for storage? In addition, other considerations should be taken into account, such as compliance with and response to relevant laws and regulations and industry regulations. Deploying nas12 and stainless steel super large liner connected to SAN storage is a good solution, which enables managers to integrate decentralized NAS filers, enhances the flexibility and scalability of the system, and provides convenience for enterprises to upgrade file systems and manage back-end storage arrays. However, using NAS gateway will also cause a series of new problems. For example, NAS gateway is connected to the disk array based on fibre channel through IP network, which is easy to develop into a performance bottleneck or single point of failure. Enterprise users should make a good plan when deploying the network

in high-end NAS applications, the NAS head is often used as the control end of the NAS server, and the optical disk array is connected to the NAS head through San or Das to provide it with a high-performance, high-capacity, high availability storage back end. At present, there are two main types of NAS handpieces on the market. One is the large storage subsystem bundled with disk array, such as fas980 series produced by NetApp; One is independent devices, such as NetApp's gfiler, which can connect different types of storage arrays, multi-layer storage, and even storage devices from different manufacturers, focusing on the development of ultra-high temperature non oxide ceramic materials. It is worth mentioning that the above two types of products are connected to the back-end disk array through fibre channel

using an independent NAS gateway to integrate existing NAS filers may cause the following problems:

if many users access files on the disk array at the same time, the system performance will be degraded. At this time, it may be necessary to reallocate network storage resources to users

there may be many files with the same name but different access and modification times in the system, and the pipe piston will rise. It will be troublesome to sort them out. It is necessary to compile a directory and determine the creator of the file

store different data according to the type and performance level of the disk

because NAS has added support for iSCSI protocol, many enterprises have chosen it to complete file level or block level transmission services; In addition, it can dynamically re classify the data on the back-end storage array, optimizing the performance of old and new data. Realizing support for heterogeneous systems has become the development direction of NAS related suppliers. As their products are certified and tested by more and more disk array manufacturers, users are no longer limited to disk array products produced by one manufacturer. Moreover, more and more vendors are now adding support functions for multi-layer storage and various policy management tools, making the data migration process between different storage tiers more transparent. Given that there are many brands and models of NAS related products on the market, it is recommended that users should distinguish between primary and secondary when evaluating product performance, and be sure to include the following key configurations and performance:

Ethernet port for connecting to the server

support NFS protocol and CIFS protocol

support multi-layer storage

manage data according to user-defined policies

features such as snapshot replication Establish advanced storage management functions such as image

in addition, combined with the future development needs of the enterprise, The following performance indicators can also be included in the evaluation:

support iSCSI technology

optical ports that can connect NAS to external storage arrays

support disk arrays of different brands

dynamically configure and expand volumes and file shared resources

reclassify data on back-end disk arrays

share files with remote sites

support global namespaces (end)
