So Guys, all you guys know them, Netapp and EMC both of them are giant in the storage industry. Now EMC release its new OS name OneFS a One File system according to them this OS make them the only best in the industry of storage but once again there is one more sophisticated, user friendly and decent OS named Ontapp lies under the tree of NetApp. I have read both of them just get the main difference between them i.e. Architecture vise, volume vise and performance vise. The Main similarity between Ontap and OneFs is both of them can support tens of petabyte without any problem and hinderence in their performance.
The picture itself can tell you the whole story but still I am going to elaborate about Ontap and OS. so let start:
NetApp® Data ONTAP® 8.x software delivers a unified storage platform that enables unrestricted, secure data movement across multiple cloud environments and paves the way for Software-Defined Data Centers, offering advanced performance, availability, and efficiency. Data ONTAP clustering capabilities can keep your business running nonstop.
More organizations use Data ONTAP than any other storage operating system*. In a single, feature-rich platform, clustered Data ONTAP lets you scale your infrastructure without increasing IT staff. Benefits include:
- Perform storage maintenance, hardware lifecycle operations, and software upgrades without interrupting your business.
- Eliminate planned and unplanned downtime.
- Reduce storage costs by using the most comprehensive storage efficiency offering in the industry.
- Consolidate and share the same infrastructure for workloads or tenants with different performance, capacity, and security requirements.
- Scale capacity, performance, and operations without compromise, regardless of application.
- Scale SAN and NAS from terabytes to tens of petabytes without reconfiguring running applications.
In traditional NAS systems the file system, volume manager, and the implementation of RAID are all separate entities. Each entity is abstracted from the other. The file system is responsible for the higher level functions of authentication, authorization. The volume manager controls the layout of the data while RAID controls the protection of the data. The functions of each are clearly defined and separate. OneFS creates a single file system for the cluster that also performs the duties of the volume manager and applies protection to the cluster as a whole. There is no partitioning, and no need for volume creation. Because all information is shared among nodes, the entire file system is accessible by clients connecting to any node in the cluster. Because all nodes in the cluster are peers, the Isilon clustered storage system also does not have any master or slave nodes. All data is striped across all nodes in the cluster. As nodes are added, the file system grows dynamically and content is redistributed. Each Isilon storage node contains globally coherent RAM, meaning that, as a cluster becomes larger, it also becomes faster. Each time a node is added, the cluster's concurrent performance scales linearly.
OneFS, which is a distributed cluster, file system. This means that a single file system spans across every node in a storage cluster and, as nodes are added, that file system automatically redistributes content across the entire node. Data redundancy is accomplished by striping data across the nodes instead of the disks so that redundancy and performance are increased. For the purposes of data striping, you can consider each node as an individual device.
There is no single master device that controls the cluster. Each node is a peer that shares the workload and acts as a controller for incoming data requests independently, preventing bottlenecks caused by multiple simultaneous requests. This also prevents outages caused by hardware failures since there is no single controlling interface to the cluster.
