Editor's Notes
- Dell’s data protection mission is to protect all of a company’s data assets and applications, Simply put: Everything; Every Time; On Time. This means our products are designed to protect all types of information assets, from unstructured data residing on networked storage devices; to mission critical applications that are essential to daily operations regardless of the environment- physical, virtual or in the cloud. With many companies running 24 by 7 operations; our products help administrators reduce or even eliminate their backup windows. In addition the ability to restore data quickly by providing access to that data in under a minute is often a requirement, especially for mission critical applications. What this means to administrators is that Dell’s data protection solutions can help them reduce the costs associated with application downtime by providing the tools needed to manage their service level agreements in accordance with the company’s business objectives. Dell data protection solutions also help control the IT budget by optimizing storage utilization as a businesses storage capacity needs grow. In IT- time is everything!
- Purpose of this slide: Explore customer storage and data management pain points Talking points: The data profile in today’s organizations is changing. While small, random access file and transaction data was the key component of storage within the organization in the past, over the last decade, given the rise of the web and more sophisticated high-performance applications, unstructured data in the form of large files is overtaking structured data. Why is this important? Structured means small bits of data have been organized into rows and columns so they can be retrieved by a user based upon a question, or query, that the user presents. Unstructured data is presented as whole based upon the organization of a file system or application. Is your data an asset or a burden? With the explosion of data and the proliferation of devices that create, access, and store data, how do you find all of your data and how do you get control of it? Without knowing the importance of the data how do you decide what data to keep and where to keep it to meet your various needs? And, even assuming you can answer these questions, how do you provide data to key stakeholders so they can take decisive action? No wonder unstructured data growth was identified as a challenge for data storage in a recent IDC study (IDC – Structured Versus Unstructured Data: the Balance of Power Continues to Shift – Mary 2014). The explosion of data in organizations – and its continued exponential growth – make storage a critical element that organizations must not fail to address in their IT strategy, while on the path to Efficient IT.
- The growth of all data – both structured and unstructured creates multiple challenges for companies of all sizes – from Small-Medium Businesses to Large Enterprises and Public organizations: Backup – failing to meet backup windows or the inability to meet Recovery Point Objectives (desire to recover data to a specific point – i.e. last incremental update or change) will put businesses at risk. Slow backups that aren’t complete within allocated time periods also run the risk of depleting CPU resources needed to be at peak performance when production systems are active. And finally, the rise of virtualization has made backups of multiple VMs as well as physical servers a complex task. Tape management – for those firms still backing up to tape systems, the inability to maintain the media and recover data in a timely fashion is stressful. Also, although tape systems are cheaper than disk, the increase in data volumes finds continual spending for tape media to backup the same information over and over again an expensive proposition. Disk management - here simply put, growth adversely affects overall backup disk capacity and IT resources…. Companies are increasingly turning to technologies such as deduplication to help keep the growth of disk media in check with the rise in backup data volumes. In addition, companies don’t want to have to constantly monitor their backup environment to see application version levels are in synch and if backup jobs aren’t exceeding the capacities of their storage systems. Restore – backup is no good without the ability to restore data within the time period expected by the business. However, all too often data isn’t recoverable quickly enough to meet the demands of business. And often, IT staff don’t have the proper time to test data recoverability until disaster strikes. For a disaster recovery plan to succeed their needs to be enough bandwidth to replicate data back to the central site from the recovery site. But bandwidth is expensive so it makes sense to keep the amount of data replicated to a DR site to a minimum. In addition, protecting data at remote or branch offices becomes an expensive burden as data volumes grow.
- Based on the Enterprise Server Group report “Deduplicated Backup for the Enterprise” published December 2008. Actual results will vary with data type, change rates, retention period and back-up methodologies. What is de-duplication? As a technology de-duplication is about reducing and or eliminating redundant pieces of data. So let’s take a look at the three different key types that we mentioned, source, server and target based deduplication.
- One way to do deduplication can be through single instancing – Single Instance Storage. An example of single instance de-duplication is when you have an email,– that might go to 50 people and it might has a PowerPoint attachment. A single instance dedupe engine can maintain only one copy of that attachment or one of that instance. These are typically done at the source or the application level of de-duplication. You can also do de-duplication at a backup server. Many backup applications that we support have the ability to do this file level type de-duplication. This has the advantage of reducing the data that flows from the backup server and its backup appliance, however this is very CPU intensive. What the DR Series does is it deduplicates data at the target. We believe this is the most efficient place to process the data because it does not put a workload either on the application server or on the backup server. It allows for the deduplication to happen inline as the data is flowing directly into the DR appliance. Additionally this tremendously affects replication by reducing the chunks of data that you’re transmitting across a LAN or a WAN for a Disaster Recovery solution.. This can truly reduce the bandwidth requirements by up to 98 percent without having to send the same thing over and over as may occur for multiple servers and multiple types of backup.
- Performing backup’s of a companies file and application servers represents the ideal set of use cases for a Dell DR data deduplication appliance. This is true for two reasons: First the DR appliance has been optimized for large sequential write operations such as those performed during routine backups, and: Secondly, backup data consists of a lot of repetitive sets of data. If you think about it the operating system and application system files do not change very often. And as the amount of data you protect continues the grow there are always sets of static files that while they need to be protected, just do not get changed frequently or even at all. For these reasons, the more often you back up the same set of machines and the longer you retain the data from those backups, the better your storage savings will be when using the DR appliance as a backup to disk target. Now let’s look at a few of the most common data protection use cases.
- The legacy environments of many customers are beginning to change. Relying upon outdated tape systems to backup data isn’t sufficient these days considering the growth of data.
- During this training we’ll cover why and how the use of the Dell DR series can help alleviate these data protection challenges. Many of Dell’s DR customers continue to use tape – just now they’re using it as an archive for long-term retention of data. And disk to disk to tape type environments can certainly utilize the DR Appliance as a disk staging area also. You can store recent backups – typically 2 or 3 months on the DR Appliance so that you have the advantage of rapid restores and the increased protection of the deduplicated and compressed environment. Whenever you need to backup to tape, you simply use the backup server to read the data from the DR6000 and write out to tape to meet long-term data retention requirements.
- Data protection is more than just backups. It involves all aspects of information technology working together to deliver the right service levels that account for system availability, recovery point and recovery time objectives, as well as disaster recovery plans. A “one size fits all” approach will result in some applications being over-protected while others are under-protected. This is not efficient and could even lead to data loss. Dell has a complete portfolio of data protection solutions including primary storage, backup servers, tape and disk backup targets, software and services that can help our customers balance the cost of protection with the risk of data loss and service interruption. Specifically, the growth rate of data and the need to recover data quickly has meant that most companies must use more than one set of products to protect information. After taking the time to classify data based on its criticality to the organization including recovery time and point objectives, IT administrators can match the technology required to meet the data protection and budget objectives with different tiers of data at different stages of the data lifecycle. For example, to meet the need to protect mission critical applications where recovery times are measured in seconds, the replication and snapshots features of Dell’s EqualLogic and Compellent storage product families maintain continuous access to data. And although host-based snapshots are useful, they don’t provide a long-term disaster recovery solution. Therefore, Dell offers solutions to balance cost with availability that include AppAssure software and DL4000 backup appliance that use a variety of recovery techniques and continuous image-level snapshots to provide near Continuous Data Protection (CDP). The Dell data protection portfolio also includes software solutions, NetVault Backup and vRanger, protecting physical and virtual servers, PowerVault MD1200 expansion shelves for backup storage capacity, the DR Series of Purpose Built Backup Appliances and the PowerVault tape systems used to protect data for long-term retention. In this presentation we’ll cover the DR series in depth and explain how it fits into the larger set of products offered by Dell to protect and recover data as well as how the deduplication functionality of the DR series is one of the cornerstones of our strategy to help our customers manage their information.
- In light of the factors mentioned in the previous slide, it’s no wonder that increasingly companies are turning to data deduplication target appliances and software-based deduplication to help cut down on the volume of data backed up and replicated as seen in this set of responses to an Information Week 2013 Backup survey of 502 technology professionals.
- The growth of deduplication purpose built backup devices is reflected in this forecast from IDC’s March 2014 Market Tracker report. In fact in just the last quarter of 2013 more than 500K TB of PBBA capacity was shipped worldwide – a 8.0% Compound Annual Growth Rate.
- Data Integrity Features Backups are typically used when all available means to recover data on the production systems have failed or are not feasible. Backups are not verified by users on a daily basis, so it is essential that backup systems treat data protection as the most important task. The DR Series has several hardware and software features that together deliver unsurpassed levels of data protection. These features are: Software o Continuous data verification: Existing data is read back periodically and checksums compared to verify data integrity. Hardware o NVRAM (non-volatile RAM): Ensures data is protected in case of power loss. o Surface Scans: These are triggered in the event of hardware faults to report and/or correct data inconsistencies. o RAID6: All data on the DR series is protected by disks using RAID6 with a hot spare disk. This RAID level protects data against as many as two simultaneous drive failures. Continuous data verification and surface scans are performed in the background so as to not disrupt core backup and deduplication activities.
- When backing up physical and virtual servers, the data flows from the database or application servers or their SAN or NAS storage, to the backup server and then to the DR6000 Appliance. The DR appliance deduplicates the data as it’s ingested into the appliance and further compresses the unique data as it reaches its final resting place. The data is retained in the DR appliance until it is expired or archived off to tape.
- Here’s a summary of the hardware and software highlights of the DR4100 appliance. Note the configuration size range – 2.7TB – to 27TB. The DR4100 supports two expansion shelves – PowerVault MD1200.
- In this slide we’re showing how the DR4100 can be expanded using PowerVault MD1200 expansion shelves. The Global Hot Spare means 1 drive per shelf waits to jump in for a rebuild in the event o drive failure. In this picture... this equates to three hot spare drives
- Market research found that, of respondents currently using data deduplication technology, around 30% said they have experienced a less than 10 X reduction in capacity requirements; around 50% report a 10 X to 20 X reduction, and around 20% report reductions ranging from 21 X to 90X. Factors affecting dedupe ratio are – Data type, Change rate, Backup schedule (Full vs Incremental), and Retention period A question that comes up quite frequently from customers is “what will be my data deduplication savings”? The simple answer is, it depends on a variety of factors. The most important considerations being: The data type, for example databases, Microsoft Office files, image based graphic files or entire virtual machines. Each type of data typically dedupes differently than the others, backups of machines with databases or unstructured data like MS Office files will deduplicate better than backups containing scientific data or a patient’s x-ray images. The rate of change in the environment in addition to the type and frequency of each backup is another important consideration. For example, a full backup often contains more duplicate data than an incremental that only backs up data that has been changed since a prior backup was taken. The frequency of the backup runs also influences the effective ratio especially with full backup jobs. Depending on the rate of data change, a full backup will contain a high percentage of redundant data as the same information is backed up over and over again such as the operating system’s files which do not get updated all that frequently. The retention periods used for each backup operation is one of the greatest factors influencing the deduplication ratio observed by a customer. In general dedupe ratios improve over time as illustrated in this graphic. Note how the estimated deduplication ratio increases month over month. This is because as old backup data is retained and the source machines are backed up over and over again, the chances of finding duplicate data segments on the target DR appliance increases. To get the best possible rate of data reduction, it’s important that customers retain backup data for at least one month, preferably longer, and use the same DR appliance target for each client when running multiple backup jobs and more than one DR device target is available. The ability to store backup data on disk for longer periods of time is a key benefit of DR appliances because longer retention periods increase the chance of a faster recovery when needed if the data is being restored from disk instead of tape.
- Global View – is a new feature for the DR series added with the Operating System 3.0 release. It lets customers manage multiple DRs with single GUI instance. It’s important to note that: Maximum number of nodes that can be part of global view is 64 It only works with DR appliances connected to Active Directory The browsers supported are: Internet Explorer 9.0 and 10.0 Firefox 23 or higher Chrome 29 or higher Here is a screen shot from a Global View dashboard that is being used to manage multiple DR appliances. The left hand side navigation bar now includes a selection for Global View in addition to the normal individual unit specific management options. There is a Global View Summary across the top that provides key metrics for all appliances added to this instance of the Global View. The main center window of the Global View dashboard will display rolled-up statistics for each participating member and will update them every 15 seconds using a fixed periodic refresh rate. From this dashboard is easy to check the status of every DR Appliance in the global view and then drill down into a specific appliance as needed to address critical alerts, check its configuration and add new work flows.
- For cost-effective data protection for small, remote or branch offices, the DR2000v is an attractive choice since no additional hardware investments are necessary. This pure software solution delivers all the same benefits of a physical DR appliance, including deduplication, compression, replication and advanced data protection. The DR2000v is implemented at the remote site for local data protection and recovery. For disaster recovery purposes, the DR2000v replicates deduplicated data remotely to a peer DR4000/41000/6000 appliance. The DR2000v is offered in 1, 2 or 4TB (with a maximum of 8 containers) capacity points and may be ordered in packs of one or ten licenses.
- Here are some of the key facts to remember about the new DR2000v and why it’s a great addition to a disaster recovery strategy: Data Protection: DR2000v supports the same wide variety of backup software applications as other products in the DR Series and offers the same deduplication guarantees global, in-line, variable block deduplication which reduces volumes of data from backups by a ratio of 15:1. Value: Lower the TCO for remote or branch office data protection by consolidating the backup target with your existing virtual infrastructure. Or integrate the DR2000v into your converged infrastructure deployments such as the Dell VRTX system. Uses the existing backup software application in use already at remote/branch office. Ease of deployment: The DR2000v is a non-disruptive addition to existing backup and recovery environments in remote or branch offices. Because it supports a variety of leading hypervisors you can install it on existing hypervisor servers in sites where deploying a physical appliance presents logistical challenges. Business Continuity: DR2000v licenses are tied to physical Dell DR Series appliances and offer all the same features including deduplication, compression and bidirectional replication to insure data is always available for recovery. Scalability – a physical DR Series appliance can act as the peer for multiple DR2000v appliances - Max DR2000v for DR4x00 is 32; Max DR2000v for DR6000 is 64
- Customers can now save time and bandwidth during initial installation by taking advantage of replication seeding which utilizes a CIFS share within the DR or an external device to load the initial backup data workload before mounting it on the DR appliance This function can be used to seed a DR primary target (and secondary target) with data from the source – this helps to limit the use of network bandwidth for initial data synchronization The process begins by seeding the target with the source’s data saved on a third party device, i.e a CIFS mounted share on the DR stored on a USB removable device. (Data is encrypted with AES128/AES256 by default AES256. Password will be used to generate the key and validate the key. The USB device can be attached to any windows server and a CIFs share needs to be created. If one device is not sufficient, alerts will be raised when space gets full. A new device can be added to continue the seeding process until the initial workload is complete. then giving the target access to the same device and thus seed the target with a copy of the data from the source. (After seed import, seed cleanup needs to be run so as to cleanup any residual data) Once the seeding at the target is complete, replication is enabled between the source and the target and a replication re-sync is started which will transfer any data ingested after the device was seeded. After the re-sync is completed, continuous replication can start which will only transfer modified or new data to the target.
