isilon raid type

OneFS monitors every node in a cluster. Hello, I have a question on isilon Data Protection level. This file system enables the placement of data anywhere on the cluster to accommodate a variety of levels of performance and protection. With all our data in one place, we don't have to manage different types of storage systems. Heck – there’s no traditional RAID model – there is file-level RAID which makes for crazy awesome rebuild characteristics. Powered by the OneFS operating system, a cluster delivers a scalable pool of storage with a global namespace. Splitting and merging. A customer plans to deploy N+2:1 protection on a 5-node Isilon cluster. Using the five-disk RAID 5 example shown above, the system would create the pool with a single RAID 5 (4+1) RAID group. On the backend, the Isilon Cluster communicates with each node using a high speed infiniband network. Isilon has a well-integrated RAID, Volume Manger and Filesystem for Simplicity In contrast, Isilon has a well thought through concept of an integrated RAID-level, Volume Manger and Filesystem. There is no need to deal with any of the above concepts as there are no RAID arrays or Volumes/vdisks in Isilon. Every Isilon OneFS installation comes with a cluster. Dell EMC XC Series – the best path for Nutanix customers gets better! In addition to the Gen6 modular architecture, such as the Isilon F800, where four nodes reside in a 4RU chassis, OneFS 9.0 also introduces support for the new 1RU all-flash PowerScale F600 NVMe and PowerScale F200 nodes. Pop a node in, connect it up to the network, power it on and in the console you have the option to join it to an existing cluster. I am very excited about this - Isilon has always been amazing to work with and the scale out capability the way Isilon does it is very unique. This is partially due to the devices’ clustered approach to data storage, and Isilon’s special, proprietary OneFS operating system, which corrects errors in clusters as they’re presented. Nice job to the engineers at EMC!”), If only EMC had some killer encapsulation intellectual property that would help us, over time, bring Isilon tech into other packages, other form factors, and more completely into the family :-). is why you get Isilon customers noting: “as I add more nodes, my VMware environment on NFS just gets faster!”. Also, Isilon runs it’s own little DNS-Like server in the backend that takes client requests using DNS forwarding. Isilon has been one of the most innovative companies producing NAS appliances, and its products are some of the best in the industry. As much as we work to be innovative (as any company must), if you limit your rate of innovation to what you can do organically, you will be in trouble. They. Required fields are marked *, …helping to speed data through your pipes. Tweet This! Of course they also ship with different type of drive combinations: all Flash, SAS, SSD and SATA. You can decide as an administrator how the data is protected, choosing to keep as many copies of data as you want (at the expense of total available storage). I’m sure someone is working on this because, once again you don’t want to be trying to figure out how to fallback 15PB’s of data at 4am by using a command line. You select disk types and RAID configurations (RAID types and stripe widths) for a storage pool. et pourquoi pas faire un NAS pour partager des fichiers avec tous les devices. If a node is unreachable over the internal network, OneFS separates the node from the cluster, an action referred to as splitting. The connector type depends on the network design; could be SFP+ or Twinax. EMC Storage Setup and creating a CIFS enabled shared folder Main The mirrored disks are combined into a stripe. Isilon’s OneFS® does not rely on hardware-based RAID for data protection. So – this limits scale-out NAS in VMware use cases in the sense that all the traffic for a given datastore hits a single “head”, a single set of cache, a single ethernet interface, no matter how you slice it. Type. The X200 can accommodate 1 TB, 2 TB or 3 TB 3.5-inch HDDs, and up to six 200, 400 or 800 GB SSDs. Isilon does not use a standard RAID model at all, it distributes data across the disks based on how much protection you decide you need. For what it’s worth – I’ve been a big supporter of Isilon in the EMC family through the M&A dance. Very exciting days! Isilon is a scale-out NAS solution with Big Data in mind and simplicity at its core. Even my MP3 collection isn’t that large but just imagine the implications. Jason Morris | Isilon supports NFS/CIFS/iSCSI/FTP/WebDAV. For example, assume there is one storage tier in the pool. This is my blog, it is not an Dell Technologies blog. This model makes for killer, simple scale-out NAS. This means that in vSphere 4.1, only one node will service the NFS queries – but all the nodes will service the IO itself. Volume Read Protection Answer: A Question #:37 You set up a meeting to If you have a single subnet to hook things up into it works as designed and from the factory it is pretty much wide open to NFS and CIFS sharing to the whole filesystem. December 21, 2010 at 09:50 PM. If RAID 10 consists of 4 disks, the data can be protected in a case of any single disk failure. Dell EMC XC Series the best path for Nutanix customers gets better! The system then creates one or more RAID groups for the pool, based on the specified configuration. What about going forward? Oh yes. Supported distributed array types are RAID 5 and RAID 6. Anything that adds complexity, cost unnecessarily can throw the “storage brains/ports/cache vs. IOps/GB” ratios out of whack. EMC Corporation announced support for 4TB drives for Isilon‘s scale-out NAS solutions. The EMC Isilon scale-out NAS storage platform combines modular hardware with unified software to harness unstructured data. It has 6 GB of system memory per single node, which can be upgraded to 12 GB, 24 GB or 48 GB. Using the five-disk RAID 5 example shown above, the system would create the pool with a single RAID 5 (4+1) RAID group. Cela amène aussi à étudier les différents montages et à connaître les outils de manipulation de ces mêmes montages. For example, assume there is one storage tier in the pool. No worries, this is normal. These sample questions will make you very familiar with both the type and the difficulty level of the questions on the E20-555 certification test. You’ll want to probably setup quotas, hard quotas, soft quotas, etc…yep Isilon does that. Type: of data location table: Data location table: Address of or actual table: Reference count # of metadata structures referencing this one : What most arrays perform globally – hot spares, RAID levels, mirroring, recovery data – may be done on a per file basis with Isilon. Supporting a performance envelope of many GBps of bandwidth and from thousands to hundreds of thousands of IOps. a) 8 b) 96 c) 256 d) 1024 05. With the Isilon hardware (‘Gen6’), a single chassis of 4 nodes in a 4RU (rack units) form factor is required to create a cluster, which scales up to 252 nodes in OneFS 8.2 and later. Similar (but not the same) requirements exist in scale-out block and object models. Looking forward to 2018Part 1: Buy to Buy and HCI (and more), Looking back on 2017: A turbulent year but also a year of IT pragmatism. I highly recommend locking that down before putting it into production. Rapidly changing or growing demands on IT services, a proliferation of storage volumes or RAID LUNs, delays in application deployments or response to failure events are signs you should look at a Scale-out storage solution from Isilon. Splitting and merging optimize the use of nodes without your intervention. We currently have a 13 Node isilon with OneFS 7.1 and 130 TB of "physical' storage space with a Data Protection Level of +2. Integrated RAID: no. Good thing is it accepts most standard authentication protocols (Active Directory, LDAP, NIS, etc). If only…, If only EMC had a extensible modern FLEX-based Unified UI (look at this partner feedback from twitter: @veverything “customer decided to go with the EMC storage solution based solely on Unisphere. Isilon capte BCE RTL Pour mutualiser la diffusion de 15 chaînes TV This is a Press Release edited by StorageNewsletter.com on May 3, 2010 at 2:55 pm . The advantages of these both array types are used, thus the result is a fault tolerant array with higher performance. XtremIO and AIX Jam Session – Journey into ODM and Powerpath, EMCWorld 2015 – VMAX3 Replication and SRDF Updates, EMCWorld 2015 – EMC Elect Session with John Roese – EMC CTO. Each node will have X amount of drive slots depending on the type. Unlike other designs in this space, there aren’t dedicated metadata nodes, lock management nodes, caching nodes. type of workload(s) The Solution design must be application aware Eliminate the architectural compromises e.g. One feature of Isilon that we’ll talk more about later is that it doesn’t use RAID protection. The green in the diagram below are “elements in a 3 node cluster which are actively servicing a given VMware NFS datastore”: That diagram (thanks John!) But, there’s also something that could happen and would be an easier thing. Dynamic pools provide numerous benefits over traditional pools. 0000010038 00000 n 0000002438 00000 n After a 3 hour Webex session, the engineer pointed to KB 334043. Dell EMC PowerScale (Isilon) is ranked 4th in NAS with 3 reviews while Sonexion Scale-out Lustre Storage System is ranked 16th in NAS. I’m going to stay silent until the Isilon deal closes – as people have seen/learnt over the last year, these things aren’t done until they are done, so this will be my only post on it for a while. Content published here is not read or approved in advance by Dell Technologies and does not necessarily reflect the views and opinions of Dell Technologies or any part of Dell Technologies. Isilon is a cluster-based storage array that is based off of industry standard hardware, highly modified FreeBSD, and can scale to a massive 15PB’s in a single filesystem using it’s OneFS filesystem. If you are into educational research, and need to have someplace to put everything, Isilon excels at that. We do have different nodes, but they all get administered the same way, so we don't have to relearn different things, such as how to manage the RAIDs, RAID groups, and different protocols. It is kinda a poor-man’s load balancer of sorts but it is very smart and can load balance clients across multiple network links. We do have different nodes, but they all get administered the same way, so we don't have to relearn different things, such as how to manage the RAIDs, RAID … 11x WD+seagate NAS/ENT drives (raidz3) [varying sizes over 3TB] 24x 2.5" (pools for SSD boot, jails, system, vms) Show : freenas-boot. Isilon offers a variety of node types that fit just as easily into smaller IT shops with hundreds of users as it does for larger enterprise datacenters supporting thousands of users. Ensure continuity of service on server resets. Isilon also offers a choice of enterprise data backup and disaster recovery options. Question #:36 Which type of data is stored in Endurant Cache of an Isilon node? While replication is pretty cool (kinda snapshot based, etc). WHITE PAPER: One of the most important decisions that you have to make when deploying a new storage solution is what RAID type(s) to use. For example, a three node cluster could sustain the loss of one entire node and keep on keepin’ on. Using Isilon SnapshotIQ, how many snapshots can be created at the directory level? Un système de stockagegénéralement équipé de deux contrôleurs et de tiroirs de disques (Enclosures) Un SAN doit être résiliant à la panne, ainsi les composants sont redondés: 1. deux commutateurs FC ou iSCSI 2. deux … Data Protection is formed using mathematical algorithms instead of using traditional RAID … December 22, 2010 at 11:28 AM. ISILON SYSTEMS 3 types of applications require a single fast data connection (across a single or multiple links). OneFS is a distributed clustered file system that runs on all nodes in the cluster. If you were to use RAID 5 (4+1) and you asked what the overhead for this protection is, it would be simple (1/5 - 20% of your disk capacity would be used for protection. Moreover, it offers users 1-disk redundancy to protect data during drive failures. The Isilon X200 has a maximum raw capacity of 36 TB per node, and fits up to 12 drives, of which six can be SSDs. For more information about the isi status command, see the Isilon OneFS Command Reference available on EMC Online Support. But for many, it’s… less than ideal. I have a Virtual Isilon Cluster setup in my home lab. N must be larger than M. For many N+M protection levels, there are no RAID equivalents. What is Isilon? Everything is just a single brand. Both the traditional Gen6 chassis and the PowerScale stand-alone nodes happily co-exist within the same cluster. Isilon Data Lake Array Isilon Node 4x Dell EMC Isilon X410 102TB HDD / 3.2TB SSD 256GB 2x10GE and 2x1GE Isilon Switch 2x QDR IB Switch - 8 Port, 1U, 1PS Table 3. From my experience, I have to agree, the more you scale out the faster your NFS datastore get's - the throughput on our cluster was unbelievable! You can follow this conversation by subscribing to the comment feed for this post. And yes, in case you are asking this is the same OS that another Storage appliance is using: NAS4Free! Heck – there’s no traditional RAID model – there is file-level RAID which makes for crazy awesome rebuild characteristics. N must be larger than M. For many N+M protection levels, there are no RAID equivalents. Individual node platforms need a minimum of three nodes and 3RU of rack space to form a cluster. Unlike a RAID system, an Isilon node can rejoin the cluster without being rebuilt and reconfigured. Storage Admin? Not only do those massive engineering investments in UI homogenization and encapsulation enable us to accelerate ourselves by making merge internal assets (I’ve already pointed out how it accelerated our EMC Unified Thin abilities, our FAST VP capabilities, our compression capabilities) , it also makes EMC able better leverage M&A as a strategic option. Isilon Storage Node Types Seems to be that EMC is changing from "Where Information lives" to "Where Companies Lives". It is because behind the scenes, the data is being rebalanced across all the nodes, adding more and more backend bandwidth and more IOps. Dell EMC PowerScale (Isilon) is rated 9.0, while Sonexion Scale-out Lustre Storage System is rated 0.0. Isilon scale-out NAS overview. But – all that doesn’t (naturally or immediately) translate into simple Unified storage model, or killer scale-out block capabilities. And they have 1400+ customers in every possible size, segment and vertical. You don’t want to show some rogue user on your network a fileshare that could potentially be as large as 15 Petabytes. A minimum of 4 disks is required to build this type of RAID. Dell EMC VxRail - now bigger, stronger, faster! How much capacity will be used to store a 1024 KiB file? | Happy Holiday Blog post Virtual Geek Out! | Je vous propose le découpage en trois parties pour ce petit tutoriel, conçu un peu comme un aide-mémoire à l’intention des administra… Reblog OneFS can use all the resources – IO, compute and memory – in every node in the scale-out storage cluster to efficiently stripe data over all available devices. This automated RAID management system allows users to create and expand storage volumes, and gives them the option to migrate RAID types without requiring details on the RAID setup. On an Isilon system this would not be so simple and we'd need more information for calculating the overhead and therefore the raw capacity needed; What is the protection type? This enterprise-ready solution combines scale-out NAS data storage and Hadoop analytics capabilities with services, training and certification, and customer support from a single vendor. Wrapping this up – I’ll restate what I said earlier…, But… EVERY EMC platform are all x86-based commodity hardware platforms. Dynamic pools use advanced RAID techniques and distributed sparing to offer better storage utilization and more simplified planning than traditional pools. Here is a Visio type diagram of the Isilon Architecture: Why Isilon is awesome. Home » Systems (RAID, NAS, SAN) » Isilon NAS Supporting 4TB HDDs. For more information about the isi status command, see the Isilon OneFS Command Reference available on EMC Online Support. Looking forward to 2018: Vertical Stack Wars are upon us. Il y a peu, nous avons vu comment exploiter les fonctionnalités d’une image initrd. For those that need scale-out enterprise block storage – EMC has a “tactical nuke” killer answer in VMAX. And I’ll say something I often say again…  Take a look at this slide I’ve been presenting since VMworld for ideas on the fun stuff going on – see the hint that has been in there for a while, highlighting so it’s obvious :-), So consider this blog a partial answer to “What I think it means…”, and also a “more to come” :-). This allows customers to granularly select an appropriate price, So… note – I wrote this on Nov 15th, right after the deal was public, but before it closed. Isilon RAID Data Recovery June 23, 2014. Connector Activation Criteria. OneFS monitors every node in a cluster. One of the most consistent was that the way that it scaled out was very simple. The Isilon nodes. ». Arguably a cluster is a group of nodes. Modular Infrastructure Configuration - Isilon Data Lake Array Networking Data Network Switches 2x Dell EMC Networking S4048-ON 10GbE Switches Management Network Switches Now they have more resources for engineering and go-to-market (, There is a VMware angle to scale-out, extreme performance – aka “Big Data NAS”. It’s time for change, and change = renewed invention, renewed vigor, renewed discovery. Isilon IQ Accelerator - NAS server overview and full product specs on CNET. 2. I’ve discussed this in detail here. These Isilon nodes contain a variety of storage media types and densities, including SAS and SATA hard disk drives (HDDs), solid-state drives (SSDs), and a configurable quantity of memory. This could easily make every ESX host access a datastore via a different IP, which means you would scale up everything up – CPU, ports, cache, and the backend all together. Which data protection does Isilon use? a) 1024 KiB b) 1280 KiB c) 1792 KiB d) 1920 KiB 04. In conclusion… Welcome Isilon – I’m very happy to have you part of the family! Splitting and merging optimize the use of nodes without your intervention. The system stores and manages data in the Isilon storage cluster by providing a single file system that operates outside the constraints of traditional scale-up constructs such as RAID groups. RAID 5 – Stripes data with parity – Striping for performance, and parity for data protection. The beauty of Isilon is there OneFS… and it means just what it says … there is only one file system that spans all nodes in the cluster, and it manages everything: the RAID, the volumes, and the file system. Explaining #4 (Unified vs. Scale-Out) a little more…  Before any acquisition (small or large) one of the most important things is talking to customers. Unlike a RAID system, an Isilon node can rejoin the cluster without being rebuilt and reconfigured. On an Isilon cluster you can enable N+1, N+2, N+3, or N+4 protection, which allows the cluster to sustain two, three, or four simultaneous failures without resulting in data loss. That angle falls into “some today, but even more over time” (more on this below). If you were to use RAID 5 (4+1) and you asked what the overhead for this protection is, it would be simple (1/5 - 20% of your disk capacity would be used for protection. Of course! The unified software platform provides centralized web-based and command-line administration to manage the following features: 0000002603 00000 n Some OneFS commands require root access, but if you do not have root access, you can … | Save to del.icio.us. Posted by: Area served. They even have the “Scale-Out NAS” equivalent of EMC FAST (fully automated tiering) – Isilon scale-out grids can be composed of different node types (IOps centered S-series nodes, bandwidth-centered X-series, or GB-centric NL nearline series), and their “smart pools” automatically move the dataset around as it’s needs and characteristics change. In these cases, the storage system must pool all resources to serve high-performance I/O to a single client. Storagecritic | 3 ISILON ECS >80% Storage Efficiency Primarily File: SMB, NFS, HDFS Scale-Out NAS Leader Scale-Out Object Leader Primarily Object: S3, Swift and Atmos 48% Lower TCO Than Public Cloud Undisputed Leader in File and … Just when the customers were thinking Celerra's were greatly improving and scaling up, EMC NAS gets rebooted. With this enhancement to its X-Series and NL-Series products, Isilon … Understand the need for survival but would like something great from EMC innovation team. (0) To allTHANK YOU for 2017, and lets dream of 2018! Your email address will not be published. | That’s not to say that Isilon’s scale-out approach isn’t good TODAY, just that when it comes to VMware, you only get half the “scale out” equation (remember, this is always for a single datastore – multiple datastores can be distributed). Obviously, over time the goal is always to further simplify (wherever possible – and embrace logical divergence where use cases are very divergent). This model makes for killer, simple scale-out NAS. Others just brute-force it with 10GbE. Show : NAS2 Backup - Baremetal. On an Isilon cluster you can enable N+1, N+2, N+3, or N+4 protection, which allows the cluster to sustain two, three, or four simultaneous failures without resulting in data loss. There’s a lot more, but that highlights what I’m talking about. Data Protection is formed using mathematical algorithms instead of using traditional RAID 5, etc etc. Show : data drives. For customers that need scale out NAS storage – EMC has a killer “tactical nuke” answer in Isilon. Show : controllers. Le réseau de commutateurs constitue une Fabric. Broadcast Center Europe (BCE) est un important prestataire technique membre du conglomérat audiovisuel européen RTL Group. Networking is kinda easy. Powered by the OneFS operating system, an EMC Isilon cluster delivers a scalable pool of storage with a global namespace. « Chads World World Debut. Traditional and distributed arrays can co-exist in the same pool. I think it’s an important category (very scalable scale-out NAS – categories where SONAS, Ibrix, Exanet and others play) – and one that Isilon are clearly very, very good at, and one that frankly, EMC and other NAS leaders on their own were not that good at. Rather it's a scale-out architecture. Holiday Gift Guide 2020. OneFS is a distributed clustered file system that runs on all nodes in the cluster. This model makes for killer, simple scale-out NAS. Replication it does…to another Isilon. VMAXHumpday, 12/17/2014 – VMAX3 Unisphere Overview, a First Look. You can have a big giant filesystem across all the nodes. You’ll probably want to setup snapshots, etc…yep Isilon does that (It even works with the previous versions tab on Windows shares so users can self-service restore their files if they need too). With Isilon you don't setup raid groups. extreme scale-out transactional behavior and designs. OneFS is built on FreeBSD 10. ISILON SYSTEMS 3 types of applications require a single fast data connection (across a single or multiple links). BTW – remember - when we’re talking about “scale-out”, you can have hundreds of Isilon nodes in a scale-out cluster. Or if you want to start out a little small and grow as your data grows without ever having to do another forklift upgrade…isilon is really cool too. For those that need internet-scale scale-out object storage – EMC has a “tactical nuke” killer answer in Atmos. Write Volume Read Protection Answer: A Question #:37 You set up a meeting to gather information on a new project with the IT manager and plan to use a workflow profile assessment (WPA) to document the requirements. The command below succeeds on the monitored host Command: if [ -f /usr/bin/isi ] ; then echo ms_hw_isi_found ; fi Output contains: ms_hw_isi_found (regex) The command below succeeds on the monitored host PDF | This paper describes performance test results for running Kafka with Dell EMC Isilon F800 All-Flash NAS Storage. Happy holidays all! The purpose of this Sample Question Set is to provide you with information about the Dell EMC Isilon Solutions and Design Specialist for Technology Architects exam.

Unified solution Ready for future requirements & challenges . The most common types are RAID 0 (striping), RAID 1 (mirroring) and its variants, RAID 5 (distributed parity), and RAID 6 (dual parity). You select disk types and RAID configurations (RAID types and stripe widths) for a storage pool. You could achieve a similar effect (admittedly much more manually) on an EMC unified platform by spreading a filesystem across more and more spindles. Provide the data network services At least 2 per server. Isilon now also claims compatibility with Kubernetes via its own Container Storage Interface (CSI) volume plugin. Congrats on getting Isilon. I’ve also done a handful of installations now and it really is good. Isilon NAS Supporting 4TB HDDs Isilon NAS Supporting 4TB HDDs This is a Press Release edited by StorageNewsletter.com on February 1, 2013 at 3:35 pm . Why not have one Unified array for all type of data from 1 TB to 100 PB that can support federation, cloud, backups and so on? Dynamic pools replace the previous pool technology, now referred to as traditional pools, as the default pool type for all-flash systems. You get very scaleable backend performance, but for a single datastore, are still limited to the bandwidth of a single node (hundreds of MBps). COVID-19. What does that mean to you Mr. So smart, that Isilon calls it “SmartConnect”. Happy Holiday Blog post Virtual Geek Out! Type: of data location table: Data location table: Address of or actual table: Reference count # of metadata structures referencing this one : What most arrays perform globally – hot spares, RAID levels, mirroring, recovery data – may be done on a per file basis with Isilon. Isilon has a well-integrated RAID, Volume Manger and Filesystem for Simplicity In contrast, Isilon has a well thought through concept of an integrated RAID-level, Volume Manger and Filesystem. Note: for Isilon OneFS v8. In these cases, the storage system must pool all resources to serve high-performance I/O to a single client. Future vSphere releases could also vary the NFS repository by not just referring to it by IP address and export, but by HOSTNAME, IP address and export. In NAS land we’re talking 10PB or more, many tens of GBps (or 100s of Gbps), 100+ nodes – all delivering extreme performance, balancing cache/metadata/data/ports across every node. Splitting and merging. ». This network connects storage CPU / DISK and backend networks causing the Isilon cluster to act as one unit. Shop By Price. The best athletes (and VxBlock 1000) = faster, higher, stronger! Now that I am a recent Isilon Certified Storage Professional I am frequently asked: “So what is it?”, “Is it easy?”, “What does it do?”, “Is it right for me?”. Isilon offers a variety of node types that fit just as easily into smaller IT shops with hundreds of users as it does for larger enterprise datacenters supporting thousands of users. Madness, VMAX’s and a year’s gone by. 0000010038 00000 n 0000002438 00000 n After a 3 hour Webex session, the engineer pointed to KB 334043. Degraded RAID array mode. Scale-out models require a different approach to resiliency – big failures can only partially affect overall system envelopes. If you are a big data shop that thrives on large media files, pictures, videos, etc…  Isilon excels at that. Others just balance across many datastores. You can decide as an administrator how the data is protected, choosing to keep as many copies of data as you want (at the expense of total available storage). In the next coming weeks I’ll be attempting to do a few videos of my demonstrating  the interface in the Lab. No re-configuring of disks, no busting out a floor tile rolling another array into production and more importantly no late-night migrations of data when you would rather be at home watching Qui-Gon Jinn battle with his mystical green lightsaber. RAID 10 is a combination of RAID 0 and RAID 1. Degraded RAID array mode. Need some real cool innovation like "Symmetrix" of the past from EMC. While we need to find ways to leverage TONS of CPU cores in the commodity hardware we use in EMC Unified platforms, it’s not. a) RAIN b) FEC c) RAID d) WAFL 03. Standard OS sizes - 300 1 TB drives. Hope I am right thinking something special may be cooking at EMC, Posted by: This means EMC has great portfolio answers for: Best in breed inline dedupe for backup (Data Domain), These capabilities that are second-to-none. Any file query can come into any node, and be serviced by all the others. The more duplicate copies of data you want to keep, the less total storage you have available … Everything is just a single brand. The key features of the EMC® Isilon® scale-out network-attached storage (NAS) make it an ideal independent storage solution that can be shared by the individual departmental PACS. The system then creates one or more RAID groups for the pool, based on the specified configuration. Internal HDDs . Well it means you are spending less time carving out luns and more time looking like a hero to your managers. When a file is written it is spread across all nodes using parity calculated by which level you set the whole or parts of the cluster to using a Reed Solomon error correction coding.
