Such a high level of redundancy is unparalleled by any other storage solution. If one of the servers goes down, the other devices within the same network pickup the slack. Better redundancy: Since the servers within the SAN function as one cluster, you aren’t necessarily accessing one particular device.This a major plus, because downtime is expensive. You can replicate rapidly and get your environment up and running quickly. Disaster recovery: Replicating data from your primary location to an offsite SAN is easy.As it is an entirely distinct network, SANs won’t cause bottlenecks like other storage solutions might. Even though the data from a SAN may travel, the SAN itself is transparent to the client OS, allowing the data to be stored quickly. Fast backup: The fact that client OSs see the SAN as attached storage allows for more rapid backups.With your servers using internal hard drives less (or not at all), they will naturally consume less power and run at a cooler temperature. High performance: A SAN means that other devices in your network won’t need to use local storage, allowing them to run more smoothly.A SAN is more than just one device, it is a networkof storage devices that work together as a single cluster. SANs are complex, interwoven systems most frequently used with mission-critical data and databases.Īs a separate network, a SAN moves resources off of the LAN (local area network), creating a separate, high-speed, more organized environment that can be accessed by each client OS as if it were directly attached storage. SAN is a dedicated network that enables servers to share a pool of storage resources. SAN-Storage area network SAN-Storage area network Its straightforward architecture and easy implementation make it great if you’re looking for a “quick fix,” but it leaves some storage needs unaddressed. In the end, a NAS is a great auxiliary storage device, but it is not going to solve all of your problems. Network dependent: Since files are typically shared with NAS devices over the LAN (local area network, also used for normal traffic), they can cause congestion or can be effected by other traffic on the LAN.Minimal speed: With low throughput and high latency, a NAS is not fast enough for high performance applications.However, too many NAS devices can lead to other issues like NAS sprawl. Limited scalability: A NAS is limited to its own resources, meaning you can only scale by adding another NAS.Since it can’t be used for things like internet searches (which might lead to viruses or malware) it is a more efficient storage device. Specialization: The very fact that a NAS does nothing but storage makes it more reliable.Inexpensive: Although prices naturally vary based on the size and quality of the NAS, as a general rule of thumb a NAS is an affordable storage solution.As you’ll see, this is a major difference between NAS and SAN. This also means that using a NAS does not require any changes to your existing network architecture-it’s a plug-and-play solution. Fewer moving parts equal fewer potential points of failure. A simpler architecture means simplified management.
Simplified architecture: NAS is built just like a desktop or server.Consolidated security: As a single system for file storage and distribution, a NAS consolidates and centralizes data protection.At its base, it is built with either SAS or SATA disks arranged in a RAID it is then attached to devices over ethernet.Įssentially, NAS is a highly specialized file server and because of its hardware, software, or specific configuration, NAS only does storage. NAS is a data storage device connected to a network providing data access to clients. NAS-Network attached storage NAS-Network attached storage But don’t let the re-arranged letters (also known as a “ semordnilap“) confuse you-there are major differences, pros, and cons to each solution.īelow, we compare the difference of SAN vs NAS to help you determine which solution would benefit your environment most. SAN and NAS are two of the leading storage solutions that are commonly compared and confused because of their similar acronyms. The importance of data storage grows daily, and this means 1) you have a lot of storage options to sift through and 2) making the right choice is more important than ever. Now, there are personal computers that come standard with a terabyte hard drive. Can you think back to 2001? The thought of using a terabyte of storage seemed like a grossly unnecessary amount of space.
