NameNode. Cloudian HyperStore offers more capabilities that boost interoperability, data durability, and operational efficiency. Erasure coding saves capacity, but impacts performance, especially if erasure coding is performed across geographically dispersed nodes. Because a failure of this node during a restore could cause significant problems, all activities written to the Cassandra disk are mirrored. Ask any IT manager how much data they are prepared to lose, and the answer is always the same — zero. The possibility of loss always exists, but companies can take steps to reduce that possibility, and do so in an economically responsible way. Cloudian HyperStore ... Erasure coding enables deep archive efficiency and flexible redundancy, giving you robust data protection without consuming precious disk space. HyperStore est aussi capable de gérer le concept de tiering … This is why EC works … This is done primarily to create up-to-date copies of data so that in the event of a disaster data may be restored. The following two figures show how replication (with a replication Cloudian's HyperStore Operating Environment software provides enterprise object storage. block to three DataNodes; EC, on the other hand, still needs to stripe the data to data With RS (6,3), each block group can hold up to (128 MB * 6) = 768 MB of data. That means it’s not enough just to protect your data — you must also select the best way to protect it. Available as either ... Data Protection Replication and erasure coding via storage policies Redundancy Hot-swappable disk drives 4x hot swappable power supplies No single point of failure Non-disruptive online software upgrades CPU 4x E5-2620 v4, 8 core (2 per node) Memory 256GB (128GB per node) Network Interfaces 4x 10GbE (10BaseT or SFP+, 2 per node); … 128 MB is the default block size. size (in case of RS(6, 3) it is (6 * 1) MB), the number of actual data blocks is less As shown in the following figure, the RS(6,3) EC policy ensures that the number Thanks to server redundancy and erasure coding, object storage systems are quite resilient against hardware and site outages. bytes/blocks ratio is worse for small files which increases the memory usage of the Thanks to server redundancy and erasure coding, object storage systems are quite resilient against hardware and site outages. Read more about object storage. 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. However, the best protection against accidental or … The cluster replicates the data and can manage its recovery automatically. 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. 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. 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. Protect data using replication, erasure coding, or both; Grow to multiple data centers or regions; Professional services and 24×7 support . As with AWS S3, it only replicates new objects. After you have written an enormous amount of data, one of those bytes might not be correct. process requires CPU and network resources. The metadata engine is a critical part of the HyperStore architecture; it helps maintain the integrity of the global namespace while at the same time ensuring the searchability of the data being stored. The most complete feature set in its class. Erasure coding works best with larger files. Manage SLAs with Cloudian’s unique QoS capability.

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. HyperStore employs a unique algorithm that detects data corruption, bit-rot and other issues and then automatically cures them. Deciding on what level of data protection your data requires is a matter of understanding your company’s needs, but also understanding the variables involved. 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. This 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. 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. The Cloudian partner ecosystem delivers proven solutions for enterprises biggest capacity challenges, such as data protection, file management, and media archiving. Inside each block group, there will be 9 total blocks, 6 data In mathematical terms, the protection offered by erasure coding can … Cloudian also offers architectural benefits that preserve data integrity and also limit wear on hardware to extend its lifecycle. With unique features like object streaming and … For example, in the case of RS(6,3) with a cell size of 1 MB, 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. A key HyperStore benefit is that policies may be set across buckets or across the entire system, providing extensive management flexibility. larger files. But opting out of some of these cookies may have an effect on your browsing experience. 128 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. 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. 128 MB is the default block size. It stores metadata with objects, but also in a distributed NoSQL Cassandra database for speed. and writing data comes at a higher network cost. Users can choose which preconfigured storage policy to effect in order to protect the data. Offers data at rest protection for security compliance, Compression Table 3 lists the default EC configuration … 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. La dernière machine de Cloudian vient compléter l’actuelle appliance Hyperstore 1500 au format 1U. 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. 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. Cloudian HyperStore also adds support for flexible erasure coding schemes for data protection and disaster recovery across sites. • 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. when the replication factor is one but is faster than writing We also use third-party cookies that help us analyze and understand how you use this website. It is turned on by default. Data Protection Supports Replication and Erasure Coding Create logical storage policies for groups or users with either replication or erasure coding storage policies or combination. EC. Object replicas are employed for frequently used data. size when comparing replication and erasure coding. Higher rates of durability are available, but, typically, the more 9s you add, the more you pay for your storage infrastructure. 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. ERASURE CODING: Efficient data protection with the level of redundancy you choose. than the data blocks defined by the erasure coding policy, though the number of parity Allows you to select replication or erasure coding of data, plus single or multi-site data distribution, Consistency Level Facteur de Réplication et Erasure Coding régis par des politiques de stockage: Redondance: Disques durs échangeables à chaud 4x alimentations échangeables à chaud Aucun point de défaillance unique Mises à niveau logicielles en ligne sans perturbation: Processeurs: 4x E5-2620 v4, 8 cœurs (2 par nœud) Mémoire: 256 Go (128 Go par nœud) Inside each block group, there will be 9 total blocks, 6 data blocks, each holding up to 128 MB, and 3 parity blocks. 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. FEATURES & BENEFITS. Adding additional recovery points by increasing the number of parity fragments within a EC set, e.g. Cloudian a récemment lancé une version dense de ses appliances de stockage objet prêtes à l’emploi. This supports the minimum data and parity fragments of (4+2) where 2 is the parity. For large backup and archive workloads, erasure coding is commonly used. • CAPEX savings: Leverage Cloudian data policies (replication or erasure coding) with vSAN Direct Configuration to lower costs and improve storage efficiency. However, erasure-coding techniques are not limited to object storage. 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. Modern Enterprise Data Protection with Cloudian. size. 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.. With RS (6,3), each block group can hold up to (128 MB * 6) = 768 MB of data. To fully understand the strategies underpinning modern data protection, you need to know the terms used to describe the concepts that make up that strategy. CLOUDIAN HYPERSTORE FEATURES Cloudian HyperStore object solution combines robust availability with system management control, monitoring capabilities and reporting. PostFinance’s Cloudian deployment uses 8+2 erasure coding, which sees data split into six fragments with two sets of parity data. Erasure coding provides an answer, for very large datasets and for applications such as object and software-defined storage. 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. 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. 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 really forward-thinking execs may have chosen their customers. factor of 3) compares to EC based on the number of blocks relative to file 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. This can be slower than writing to a file Erasure Coding; Multi-tenancy; 100% Native S3; Compression Reduces the effective raw storage used to store data objects, Data Size Threshold The system compares replicated data to ensure that copies are identical. Cloudian provides 100% Native S3 object storage in your datacenter. Provides control of replication techniques (synchronous vs. asynchronous), Access Permissions To learn more about our cookies, how we use them, and their benefits. 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 enables deep archive efficiency and flexible redundancy, giving you robust data protection without consuming precious disk space. Schedule-based automatic transition (Cloudian’s term for auto-tiering) is available from HyperStore storage to Amazon S3 storage, Amazon Glacier storage, a remote HyperStore deployment, or a third-party HyperStore service. Cloudian is the industry’s only 100% S3 compatible cloud storage software. The powerful, petabyte-scale solution for unstructured data. 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. CAPEX savings: Leverage Cloudian data policies (replication or erasure coding) with vSAN Direct Configuration to lower costs and improve storage efficiency. Cloudian allows you to manage the variables around data protection — and do so on a granular level, using different policies for different buckets. 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. EC supports the following data processing engines: Hive, Mirroring avoids the rare but extremely damaging event of a Cassandra disk failure during a restore. Many enterprises may be happy to have their storage design match Amazon Web Services’ 11 9s, without the need for more. Replication supports all data processing engines that CDP supports. The list of features, including hybrid cloud streaming, virtual nodes, configurable erasure coding, and data compression as well as encryption helps set Cloudian 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. ... highly secure erasure coding, encryption for data at rest, and consolidated object and file level data backup and archiving. Six drives, nodes or geographic locations could be lost or unavailable, and the original file would still be recoverable. Cloudian ® HyperStore . Also, built-in to the Cloudian HyperStore storage system is Smart Support. Cloudian, Inc. is a US enterprise data storage company headquartered in San Mateo, California, ... HyperStore supports logical storage policies that can be configured with replication or erasure coding. Erasure coding saves capacity, but impacts performance, especially if erasure coding is performed across geographically dispersed nodes. Replication is used when people require faster access and also for cross region replication. For some organizations, however, having more than 11 9s is important. This added flexibility keeps the data protection cost-effective and affordable. 70% savings on storage costs. Because there is a delay in the copy time, the two data copies may not always be identical and therefore inconsistent. The one thing that is truly irreplaceable is their data. Similarly, when scaling the storage cluster or performing maintenance, changes in node availability are automatically detected without service interruption. Cloudian HyperStore provides storage policies (administrator selectable) for implementing data protection based on the value of the data. Cloudian HyperStore Features and Benefits 1.
