The acronyms are mirrored, and every shares two words - network and storage. Nevertheless, NAS and SAN differ significantly in style and implementation, and for that reason represent distinct solutions when it comes to what Intel® data storage product is suitable for certain business applications.
Safe and efficient data handling is really a necessary measure for any business that really wants to implement an effective storage and backup plan. Intel® is promoting several storage solutions knowing that. The first is certainly not much better than another; the most well-liked storage method simply depends upon a company's requirements and existing infrastructure. Today the functionality of the NAS and SAN are extremely similar; nevertheless, there are specific technical differences. The main technical differences from a NAS along with a SAN are:
A NAS identifies data by file name and byte offsets, transfers file data or file meta-data (file's owner, permissions, creation data, etc. ), and handles security, user authentication, file locking.
A SAN addressesidentifies data by disk block number and transfers raw disk blocks typically via SCSI calls.
When exploring the two Intel® storage networking solutions, the advantages of both NAS and SAN show marked distinctions.
First, a NAS includes a storage device or mixture of multiple storage devices attached to the existing local-area network (LAN). A NAS serves to offload the business's valuable data to some dedicated storage location that's still readily accessible by file and application servers through the corporate LAN. An average NAS answer includes a server focused on file sharing within the network having a TCP/IP connection. Intel's SSR212MA NAS Storage Answer device enables more hard disk drive space for storage to become put into a network that already utilizes main servers for other applications. The Intel® device delivers the information towards the user within the existing LAN. It's not essential for the Intel® device to become located inside a particular server. It may exist anywhere on the LAN together with multiple NAS devices.
In contrast, a SAN includes storage devices that are networked together (historically using a high-speed fiber backbone) separately in the existing corporate LAN. Intel's SSR212MA SAN Storage Server's primary approach to affix to the storage is iSCSI. This can be a more interoperable and cost-effective answer. In a nutshell, a SAN is really a high-speed sub-network of shared storage devices (machines which contain only disks for storing data) that may be accessed by users through file and application servers. The SSR212MA could make all storage devices open to all servers with an LAN or wide-area network (WAN). When storage products are put into the Intel® SAN server, they may be accessed from any server on the network. Additionally, storage capacity could be put into the SAN storage system when needed without intrusion on the corporate network. The Intel® server is really a bridge between your stored data and also the consumer.
Therefore, the differences from a NAS along with a SAN could be highlighted within their main benefits.
A primary advantage of Intel's SSR212MA SAN Storage Server is it has an effective disaster recovery plan. A SAN can replicate data owned by many servers to some secondary storage array, which may be accessed locally or remotely. Although more costly NAS devices have data replication functionality the SS4000-E NAS doesn't. Sharing storage adds flexibility because cables and storage devices don't have to be physically moved for data storage to visit in one server to a different. Furthermore, the Intel® SAN Storage Server features industry-standard hardware architectures and management tools to help lower the price of SAN systems. Due to this, IP (Ip address ) SANs similar to this Intel® server are actually at your fingertips on most companies.
The advantages of Intel's SS4000-E NAS Storage Answer include techniques to protect, manage, and share information. The unit allows clients to gain access to exactly the same group of files within the common corporate network. Data sharing is performed quickly while keeping the safety of getting another storage device. The price of NAS devices, such as the SS4000-E, has dropped recently as well as their growing storage sizes are attractive to small company as part of their data backup plans. Being an added benefit, since the SS4000-E NAS Storage Option would be always available on the web, supported information is readily available for restores at LAN speeds with no need to locate the right tape. Complete and advanced data protection is provided through support for RAID Levels 10, 5 and 1.
In summary, for any business to implement an operable storage and backup style, it has to focus on safely and efficiently handling its data. Although 1 Intel® storage networking option would be certainly not much better than another, every possesses obvious distinctions. The way the SS4000-E NAS Storage Answer or even the SSR212MA SAN Storage Server may be used depends on the requirements from the company and it is network style.
