What is an Isilon cluster?
An Isilon cluster consists of three or more hardware nodes, up to 144. Each node runs the Isilon OneFS operating system, the distributed file-system software that unites the nodes into a cluster. A cluster’s storage capacity ranges from a minimum of 18 TB to a maximum of 15.5 PB.
What protocols does Isilon support?
OneFS provides integrated support for a wide range of industry-standard protocols, including Internet Protocols IPv4 and IPv6, network file system (NFS), Server Message Block (SMB), Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), REST- based Object access for your cloud initiatives and Hadoop …
Is PowerScale and Isilon same?
Dell updates Isilon with PowerScale label, fresh hardware and other tweaks. Dell has updated its Isilon scale-out filers with new PowerScale branding and products as well as S3 object access and a DataIQ data analytics feature. It has two unstructured data storage products: Isilon for files and ECS for object storage.
What is the difference between PowerScale and Isilon?
It has two unstructured data storage products: Isilon for files and ECS for object storage. 0 of the PowerScale OneFS operating system, the way is paved for a unified Isilon/ECS product line. However, ECS and Isilon are not coming together yet, with ECS meant for purpose-built object stores.
Can A deduplicated file be replicated to another Isilon cluster?
When deduplicated files are replicated to another Isilon cluster or backed up to a tape device, the deduplicated files no longer share blocks on the target Isilon cluster or backup device. However, although you can deduplicate data on a target Isilon cluster, you cannot deduplicate data on an NDMP backup device.
How does smartdedupe find duplicate blocks in Isilon cluster?
SmartDedupe deduplicates data by scanning an Isilon cluster for identical data blocks. Each block is 8 KB. If SmartDedupe finds duplicate blocks, SmartDedupe moves a single copy of the blocks to a hidden file called a shadow store.
What happens when deduplication is run at low priority?
By default, the deduplication job is configured to run at a low priority. When deduplicated files are replicated to another Isilon cluster or backed up to a tape device, the deduplicated files no longer share blocks on the target Isilon cluster or backup device.
What are the features of a Isilon cluster?
A single Isilon cluster consists of multiple nodes, which are rack-mountable enterprise appliances containing: memory, CPU, networking, Ethernet or low-latency Infiniband interconnects, disk controllers and storage media. As such, each node in the distributed cluster has compute as well as storage or capacity capabilities.
