The isi status CLI command output includes a Data Reduction field: In OneFS 8.2.1 and later, the OneFS WebUI cluster dashboard now displays a storage efficiency tile, which shows physical and logical space utilization histograms and reports the capacity saving from in-line data reduction as a storage efficiency ratio. Data Reduction pro c e d u r e s include Factor analysis, Correspondence Analysis and Optimal Scaling. Isilon SyncIQ replication copies block level changes within files, Golden Copy can only copy entire files. On top of the FPGA, the OneFS hardware off-load engine uses a proprietary implementation of DEFLATE with the highest level of compression, while incurring minimal to no performance penalty for highly compressible datasets. In-line dedupe also detects dedupe opportunities from the read path, and blocks are hashed as they are read into L1 cache and inserted into the index. When run in view mode, the command returns the compression ratio for both compressed and all writes, plus the percentage of incompressible writes, for a prior five-minute (300 seconds) interval. The new F900 features multi-processors, all-NVMe and NVIDIA GPUDirect compatibility to handle your customers most data intensive workloads. This paper focuses on OneFS, a modern file system that includes in-line data reduction, native real-time data compression and deduplication, SmartDedupe post-process deduplication, Cloning, Writable Snapshots, and Small File Storage Efficiency. Based on a write once, read many (WORM) locking capabilities. A partial block of zeroes being written to a sparse or prealloc block. Figure 16. When compression has occurred, the df CLI command will report a reduction in used disk space and an increase in available space. PowerScale OneFS 9.3.0.0 adds support for Dell Technologies APEX file storage services (File Services). For example: In OneFS 8.2.1 and later, OneFS SmartQuotas has been enhanced to report the capacity saving from in-line data reduction as a storage efficiency ratio. As such, it has the potential to reduce the amount of work that both in-line deduplication and compression need to perform. To help mitigate the performance impact, the hashing is performed out-of-band in the prefetch path, rather than in the latency-sensitive read path. A best practice is to run highly compressible datasets through the F810 nodes with compression enabled. Service choice availability may vary by product. WebThis paper focuses on OneFS, a modern file system that includes in-line data reduction, native real-time data compression and deduplication, SmartDedupe post-process We are further strengthening our data protection offerings for PowerScale with enhancements to our cyber protection offering with Superna and a new Dynamic NAS capability, enabled by our Dell EMC PowerProtect portfolio. As such, files on OneFS can contain both physical data and pointers, or references, to shared blocks in shadow stores. NAS assets are automatically discovered through communication with the NAS array. For example, consider the following 128KB chunk: Figure 6. Inline data reduction, now available across the entire PowerScale portfolio, provides additional opportunities to deliver up to 2.2x increase in storage efficiency. Take a 3D animated tour of our unique system. For instance, if SmartDedupe writes data to a shadow store, when those blocks are read, the read hashing component of inline dedupe will see those blocks and index them. When reading or writing to the cluster, a client is directed by SmartConnect to the desired protocol head on a particular node, or initiator. The server responded with {{status_text}} (code {{status_code}}). With APEX Flex on Demand (an APEX Custom Solution), our consumption-based offering is available for the Dell Technology Infrastructure Portfolio. It transforms the technology experience, delivering as-a-Service wherever it is needed so organizations can focus less on managing infrastructure and more on running their business. Under the hood, the F810 nodes use an FPGA-based hardware offload engine resident on the backend PCI-e network adapter to perform real-time data compression. Watch ESG Practice Director Scott Sinclair illustrate how IT departments can benefit from Dells offers, assurances, and guarantees. As such, it is possible to deduplicate a data set purely by reading it all. Every industry is going digital and seeking a better workflow that can be achieved with a simplified approach to managing their files. OneFS prefetch caching has also been enhanced to accommodate compressed data. Note: Because they reside on the same card, the data compression engine shares PCI-e bandwidth with the nodes backend Ethernet interfaces. In general, there is plenty of bandwidth available. Get guidance on IT solutions for your business. Once the SMB session is established and write request granted, the client begins to send the file data across the front-end network to the cluster where it is initially buffered in the coalescer, or OneFS write cache.

Archive nodes are well suited for active archive and safety and security workloads. 6 When comparing an increase in storage efficiency with the comparable Isilon nodes. Since both features use the same core components, the results are combined. Each of these blocks is then hashed and its cryptographic fingerprint compared against an in-memory index for a match. PowerScale Cyber Protection solution puts IT teams a step ahead of cyber attackers by detecting unusual data access patterns and suspicious behavior that are indicative of a ransomware attack. The logical overlay information is described under the protection groups output. And snapshots of shadow stores are not permitted because the data contained in shadow stores cannot be overwritten. Client ID trunking is the association of multiple sessions to the same client ID. WebIn-line data reduction efficiency | Dell PowerScale OneFS: Data Reduction and Storage Efficiency | Dell Technologies Info Hub In-line data reduction efficiency Compression Erasure coding can provide beyond 80% efficiency on raw disk with five nodes or more, and on large clusters can even do so while providing quadruple-level redundancy. Most Linux supports session trunking by using nconnect option which is included in the Linux kernel version higher than 5.3. This avoids the need to de-compress or recompress data to change protection levels, perform recovered writes, or otherwise shift protection-group boundaries. : The deduplication statistics do not include zero block removal savings. PowerScale OneFS and its many software features deliver enterprise-grade data protection and security including data snapshots; LAN and WAN data replication; intelligent client-failover; and Write-Once, Read-Many (WORM) data immutability. It combines that information and queues a request to an asynchronous dedupe worker thread. - Indexing Isilon snapshotsprovides users with version history and file recovery with full content searching. The purpose of the coalescer is to build up a large contiguous range of data that will make the write operation more efficient. Snapshots Granular Point in time immutable copy of data that can be retained for quick recovery as needed including from cyber attacks. A partial block of zeroes being written to a non-sparse, non-preallocated block will not be zero eliminated.

Applicable products include: all PowerStore models as well as PowerMax 2500 and 8500 models. OneFS 9.3.0.0 supports creating and managing modifiable copies of snapshots. The address space for the L1 cache is already split for data and FEC blocks, so a similar technique is used to divide it again. It also automatically balances and scales across resources, simplifying management while accelerating backups faster than ever before.. All-Inclusive Software: Includes select software needed to store and manage data. In the diagram below, an NFS client attaches to node 1 and issues a read request for a file. Since in-line dedupe and SmartDedupe use different hashing algorithms, the indexes for each are not shared directly. However, in OneFS 9.2 and later, the logical data and preprotected physical metrics are now tracked and reported accurately, rather than estimated. Abstract. Support for multi-cloud data access with maximum choice and flexibility. 4. Writable snapshots enable you to test data recovery scenarios without having to create a copy of an entire dataset. Effective to usable and raw relationships in various PowerScale configurations. 8, Everything you need to store and manage your critical data is included with your Dell storage, HCI, & networking purchase. As such, the isi dedupe stats output reflects the sum of both in-line dedupe and SmartDedupe efficiency. More than 2000 customers trust Superna Ransomware Defender for PowerScale. Both hardware and software compression implementations are DEFLATE compatible. If OneFS SmartDedupe is also licensed and running on the cluster, this data reduction savings value will reflect a combination of compression, in-line deduplication, and post-process deduplication savings. The efficiency ratio is a single, current-in time efficiency metric that is calculated per quota directory and includes the sum of in-line compression, zero block removal, in-line dedupe and SmartDedupe. Efficiency savings must be at least 8KB (one block) for compression to occur, otherwise that chunk or file will be passed over and remain in its original, uncompressed state. writes for which compression was not attempted: : If the incompressible data percentage is high in a mixed cluster, there is a strong likelihood that the majority of the writes are going to a non-compression pool.
