Cloudian a récemment lancé une version dense de ses appliances de stockage objet prêtes à l’emploi. After you have written an enormous amount of data, one of those bytes might not be correct. Find out more about object storage or locate a sales rep or channel partner in your area. Replication is used when people require faster access and also for cross region replication. Referred to as polynomial interpolation or oversampling, this is the key concept behind erasure codes. Synchronous replication takes place in real time, and is preferred for applications with low or zero recovery point objectives (RPO) that mean that data must be able to be restored to the point in time of failure. Les données ingérées par HyperStore sont protégées par distribution entre plusieurs nœuds serveurs via un mécanisme d’erasure Coding — activable à la demande — ou via un mécanisme de réplication, ce qui permet d’assurer des performances optimales tant avec de petits fichiers qu’avec des fichiers volumineux. Erasure coding (EC) is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces and stored across a set of different locations or storage media.. Cloudian’s HyperStore object storage system brings all the data protection benefits inherent in object storage, plus additional benefits that make it a particularly strong candidate for backup applications: Cloudian HyperStore is flexible, permitting organizations to design their storage protection with erasure coding and /or replication. The powerful, petabyte-scale solution for unstructured data. Cloudian HyperStore is software-defined and delivered as a turnkey, integrated appliance or software-only and runs on commodity hardware. Erasure coding works best with larger files. With RS (6,3), each block group can hold up to (128 MB * 6) = 768 MB of data. Read more about object storage. It is mandatory to procure user consent prior to running these cookies on your website. Replication supports all data processing engines that CDP supports. Larger nodes can be used if capacity is the major concern. Cloudera recommends at least a 10 GB network connection if PostFinance’s Cloudian deployment uses 8+2 erasure coding, which sees data split into six fragments with two sets of parity data. Not so long ago, if you asked a business executive, “What is the most irreplaceable part of your business?” they might have pointed at their building or their employees. The potential risks to your data can be as subtle as the malfunction of tiny areas on a disk drive or as enormous as the failure of an entire data center. FEATURES & BENEFITS. size. In mathematical terms, the protection offered by erasure coding can … The Cloudian HyperStore is a fully distributed architecture that provides no single point of failure, data protection options (replication or erasure coding), data recovery upon a node failure, dynamic re-balancing on node addition, multi-data center and multi-region support. Cloudian HyperStore ... Erasure coding enables deep archive efficiency and flexible redundancy, giving you robust data protection without consuming precious disk space. size (in case of RS(6, 3) it is (6 * 1) MB), the number of actual data blocks is less Asynchronous replication is typically time-delayed.

Automated version creation adds a level of protection to the data and the system overall. Leverage the proven interoperability of the industry’s only 100% native S3 API. blocks and calculate parity blocks. 128 will generate more blocks than replication because of the parity blocks required. If 3x Similarly, when scaling the storage cluster or performing maintenance, changes in node availability are automatically detected without service interruption. blocks, each holding up to 128 MB, and 3 parity blocks. For very small files of sizes smaller than the value of data blocks * cell EC supports the following data processing engines: Hive, Proactive repair and auto correction features such as erasure coding, enable deep archive efficiency and flexible redundancy resulting in robust data protection. A parity block is generated when data is written, thus Replication may be synchronous or asynchronous. Cloudian HyperStore offers greater and more cost-efficient control over data protection and enables its users to do what’s best for their organizations’ data, today and for the future, with the same architecture. It also includes write-once, read-many capabilities to enable immutable … Enables data replication to public cloud, Encryption Data Availability: Data availability describes the rate at which data continues to be available at a required level of performance to end users and applications in situations ranging from normal through “disastrous.” It defines the degree or extent to which data is readily usable along with the necessary IT and management procedures, tools and technologies required to enable, manage and continue to make data available. Please note that on our website we use cookies necessary for the functioning of our website, cookies that optimize the performance. Erasure Coding Erasure coding (EC) is an alternative method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces, and stored across a set of different locations or storage media. As an example, data durability will be much lower when object data is hosted in a single node in a single data center as compared with hosting the same object data and copies on multiple nodes, each in multiple data centers, which enables much higher data durability and protection. However, erasure-coding techniques are not limited to object storage. This replication approach is typically more expensive to implement as the network infrastructure between sites becomes a limiting factor and money needs to be spent on minimizing latency to avoid application performance impact. Cloudian supports geographic erasure coding, performing erasure coding within a data center, but using replication between data centers is often the best capacity/performance tradeoff. For example, in the case of RS(6,3) with a cell size of 1 MB, Data Durability: Durability refers to data-level redundancy and protection with an aim to ensure data is never lost or compromised. block to three DataNodes; EC, on the other hand, still needs to stripe the data to data Replication may be a better choice for some clusters or locations, with EC or even different levels of EC for other parts of their storage. 10/7 configuration, improves data protection rates at a much lower cost than object copies. Cloudian stores file and object data in the native format of the public cloud, so cloud-based applications can directly access the data in the cloud without having to go through the HyperStore 7 platform. Lose that and you really are out of business. This configuration requires a minimum 6 nodes across a single Data Centers (DC). This method of data protection provides a more resilient system vs. hardware failures and makes running on a standard x86 server acceptable, which leads to lower costs. Product Features. Provides control of replication techniques (synchronous vs. asynchronous), Access Permissions Cloudian HyperStore Metered-by-Use . Erasure coding has come to prominence with its use in object storage and, by extension, in the cloud. For example, in an EC 10/6 configuration, the 10 refers to the original amount of data and the 6 refers to amount of extra data added to protect from failure. Easily meet your IT requirements for data protection and data availability with SDS policies. Not so long ago, if you asked a business executive, “What is the most irreplaceable part of your business?” they might have pointed at their building or their employees. A 1MB file would therefore require four block objects in total. The HyperStore architecture allows managers to adjust the level of data consistency across the system.

Erasure Coding; Multi-tenancy; 100% Native S3; Compression Cloudian's HyperStore Operating Environment software provides enterprise object storage. Erasure coding works best with larger files. If erasure coding (EC) is in used, it’s also important that erasure coded data be regularly evaluated and repaired to ensure that for each object, the right number of fragments exist across the cluster and that all fragments are up-to-date. Because there is a delay in the copy time, the two data copies may not always be identical and therefore inconsistent. This configuration requires a minimum 6 nodes across a single Data Centers (DC). A disk failure or node failure is not a cause for worry since there are always at least two other copies of the object available within the cluster. two or more replicas. • CAPEX savings: Leverage Cloudian data policies (replication or erasure coding) with vSAN Direct Configuration to lower costs and improve storage efficiency. Many enterprises may be happy to have their storage design match Amazon Web Services’ 11 9s, without the need for more. But the reality is that businesses have insurance to deal with the loss of a building; they can hire new employees; and they can acquire new customers. Thanks to server redundancy and erasure coding, object storage systems are quite resilient against hardware and site outages. Cloudian’s bucket-level policy setting provides highly precise granularity for SLA and management control through a number of parameters: Data Protection Control This is done primarily to create up-to-date copies of data so that in the event of a disaster data may be restored. This Provides variable storage location of data based upon the data object size, Lifecycle Policies None of the disks need to use RAID protection; the RAID approach used to be the go-to technology for data protection, but the architecture of RAID arrays imposes a time penalty that today is considered unacceptable. larger files. Its distributed architecture with automatic replication and erasure coding makes it highly resilient to network and node failures without data loss. With unique features like object streaming and … Cloudian provides 100% Native S3 object storage in your datacenter. Get started with object storage and pay nothing upfront.

Cloudian’s HyperStore allows an organization to select the appropriate data protection policy for each data set within a cluster according to the specific business and technical requirements for the protection of that data. HyperStore applies storage policies at the user bucket level. Protect data using replication, erasure coding, or both; Grow to multiple data centers or regions; Professional services and 24×7 support . If data becomes corrupted at some point in the disk storage process, it can be reconstructed using information about the data that’s stored elsewhere in the array. An object storage system extends this concept to the cluster node level, whereby data copies are placed across different servers rather than drives, providing greater protection and availability against other server component failures as well as the disk drives. replication were used, the same file would require only three block objects. Cloudian has made the investment in FIPs, Common Criteria, and DoD APL certifications. For a chunk of data less than the block size, replication writes one data Managers can set policies to control the frequency of consistency checks to match the need for system performance. For large backup and archive workloads, erasure coding is commonly used. With RS (6,3), each block group can hold up to (128 MB * The cluster replicates the data and can manage its recovery automatically. Manage SLAs with Cloudian’s unique QoS capability. Varying the number of nodes, drives per node, and number of data centers hosting the object data (and extra data copies) directly impacts the level of data durability and ability to tolerate the risk of a failure and losing an object. Some of the key parameters used in calculating durability levels for a data-protected system include usable storage capacity, number of unique locations, number of storage nodes and drives in each node, drive capacities, bit-error rate, annual failure rate of drives, average time to repair a failed drive and rebuild associated data, and the number of nodes and the number of sites that can be lost without impacting data availability.

Storage as a service Enterprises can offer storage as a service by combining on-site storage with Google Cloud services for effectively limitless storage capacity and a superior cost structure. • OPEX savings: Consolidate both traditional workloads and modern, cloud-native workloads on the same platform, eliminating infrastructure silos and capitalizing on common skills and training. CAPEX savings: Leverage Cloudian data policies (replication or erasure coding) with vSAN Direct Configuration to lower costs and improve storage efficiency. In our previous post, “How secure is object storage?”, we discussed a range of measures you can use to protect yourself against certain data-loss scenarios. This supports the minimum data and parity fragments of (4+2) where 2 is the parity. With Cloudian, you can efficiently store blocks of any size from 4 KB to multiple TB, and you can reduce storage footprint with integrated erasure coding and compression. 128 MB is the default block size. Not so long ago, if you asked a business executive, “What is the most irreplaceable part of your business?” they might have pointed at their building or their employees. To protect against an entire site disaster, data replication is used to make copies of data distributed across multiple sites. MapReduce, and Spark. HyperStore est aussi capable de gérer le concept de tiering … EFFORTLESS DATA MOVEMENT Cloudian HyperStore affords you the flexibility to put your data where you want it and easily retrieve it when you want it. The system constantly runs a background scan to verify the integrity of each object; if it detects any damage or missing data, the system will automatically build a new copy of the object. The most complete feature set in its class. Another advantage with Cloudian is that when additional capacity is needed, customers can simply add additional nodes without having to employ the same EC configuration, as others can require. The HyperStore cluster automatically balances loads across the nodes with the express intention of not overtaxing individual nodes and disk drives, thus saving on hardware maintenance expenses. you want to use EC. Erasure coding is used instead of traditional RAID because of it provides ability to scale across cluster nodes rather than being restricted to only managing disk devices within a single server as well as providing the flexibility on the number of parity fragments. Erasure coding creates a mathematical function to describe a set of numbers so they can be checked for accuracy and recovered if one is lost. Cloudian HyperStore Features and Benefits 1. NAS and … The internal Cassandra database disk records recent activity and also serves as a record of all recent actions within the cluster. This is crucial for certain regulated industries and for those organizations that have high-value data. All data is valuable — so whether only for a small amount of data or with very large volumes of data, the concern is for failures or errors in the underlying storage media, particularly in the form of uncorrectable bit errors. a 1MB file consists of one data block, rather than six, but it still has three parity As with AWS S3, it only replicates new objects. HyperStore employs a unique algorithm that detects data corruption, bit-rot and other issues and then automatically cures them. It stores metadata with objects, but also in a distributed NoSQL Cassandra database for speed. Although mirroring is the simplest implementation of data protection and delivers better performance, the cost of storage is greater due to the high storage capacity overhead. ERASURE CODING: Efficient data protection with the level of redundancy you choose. Advanced system and data management features put you in control. The basic method of protecting data is to make multiple copies of the data object and ensure the copies are located on different physical devices. Cloudian stores file and object data in the native format of the public cloud, so cloud-based applications can directly access the data in the cloud without having to go through the HyperStore 7 platform.
