Kusnetzky Group: Maximizing the Benefits of Virtualization with Real-time Compression

  1. 1. !"#$%$&$()*+,)-,,.$*/)0.)1$2*3"4$&"*$0) 5$*+)6,"47*$%,)80%92,//$0) By Dan Kusnetzky, Distinguished Analyst E X E C U T IV E S U M M A R Y Organizations are using more and more data. Much of this growth can be attributed to the increasing collection of analytical data, documents, messages, presentations and other unstructured data. Data retention requirements and the need for both backup and disaster recovery plans is causing organizations to face the fact that backup and disaster recovery procedures are time consuming. As difficult as it is to address the need to maintain backups today, the introduction of virtual servers and virtualized environments is likely to only exacerbate the problem. The proliferation of virtual environments means that there are more sources of data to include in a company’s backup and archival storage plan. Decision makers must consider the rapid growth of the company’s information assets, the challenges of backing up this data and develop concrete plans to address this issue. A sound approach is reducing the size of the data that must be stored, starting with primary data. While sound, this approach can only be successfully used if proper attention is focused on not impacting performance and compatibility with current applications and processes. Real-time compression may be the best approach because it not only shrinks primary data in real-time, but it also reduces the requirements for new and existing storage throughout the data lifecycle without impacting application performance or forcing the company to change applications, processes, procedures, or re-train IT or business staff. W H A T IS T H E IS S U E ? Companies are facing an explosion in the need for and use of data. At the same time, these organizations are facing the need to reduce overall spending on IT. These divergent trends are at the foundation of one of the many issues IT management faces today. FACTORS CREATING THE DRAMATIC GROWTH IN STORAGE Let’s look at some of the factors that are creating this dramatic data growth. ! In order to reduce staff-related costs, companies are increasingly automating previously manual processes. The newly automated processes produce additional structured and unstructured data. In both cases, additional storage capacity is required.

  2. 2. ! In order to improve sales and marketing processes and reduce the cost of customer acquisition and retention, companies are turning to the use of business intelligence and real-time analytical processing software to uncover previously hidden customer requirements. This means gathering and storing large amounts of data from customer relationship management, marketing and sales systems.! Companies are seeing continued growth in the use of unstructured data in the form of messages, documents, presentations, spreadsheets and the like as part of its operations. Regardless of where this data is being used; whether it is on a PC, a smartphone or a tablet computer; this data must be backed up.! Virtual environments are increasing the amount of data being processed. As companies begin to encapsulate server workloads into virtual machines, there are more sources of data to include in a company’s backup and archival storage plan.This quick survey covers only part of the increasing amount of data theorganization’s staff and systems are creating. What is clear is that theamount of data companies need to backup is growing rapidly. It is alsoclear that it is increasingly difficult to backup everything. WHAT PAIN DOES THIS ISSUE CAUSE?Increased requirements for data storage causes a number of painfulproblems including increased costs, difficulty finding a window of time tosuccessfully backup data and being prepared for either a disaster or foran audit. INCREASED COST AT A TIME WHEN BUDGETS ARE BEING REDUCEDDramatic growth of both structured and unstructured data usually leadsto the acquisition of additional storage devices, storage networkingequipment, and storage software. This additional equipment requirespower and cooling which only add to the high price of purchasing andmaintaining storage. Furthermore, the requirement to backup all this datameans an increase in staff time as well. Overall, this leads to ever-increasing IT costs.Since organizations are seeking to reduce IT budgets, data growthpresents a serious problem. WHEN IS THERE TIME TO BACKUP IN A 24 X 7 X 365 WORLD?Some organizations find that they simply cannot backup all of the datatheir systems and processes are creating. Operational systems are nowaccessed from customers and staff worldwide. So, operational andsupport systems must be available 24 hours a day, 7 days a week, 365days a year.In the past, IT staff would backup systems after business hours in theirhome time zone. This no longer works because systems are always inuse. There is no longer a specific time that can be seen as a window ofopportunity to backup all of the data the company is using. VIRTUALIZATION IS EXACERBATING THE PROBLEMThis issue is compounded by the increasing use of virtualizedenvironments. The Kusnetzky Group © 2011 Page 2
  3. 3. ! Each virtual server consumes and produces data. As virtual servers increase in number, the amount of data increases as well. Each virtual server has its own copy of the operating system, application software, application support software as well as database software and data. As the company increasingly relies on hundreds or, perhaps, thousands of virtual servers, the amount of data being produced rises as well.! Internet eCommerce applications, which are often based upon application and processing virtualization technology, sharply increase the amount of data an organization must store. Furthermore, that data changes rapidly enough to overrun the capabilities of many storage systems.! Organizations are making more use of modeling applications to manage risk, do non-destructive testing, develop manufacturing processes, and, of course, as a part of architectural development. These models are often huge files.W H A T W O U L D A N ID E A L S O L U T IO N L O O KLIK E ?Let’s consider the characteristics of an ideal solution to these issues. Thesolution must have the following attributes to be successful:! The solution must get control of the explosive growth of data and reduce data center costs by reducing the floor space storage, power consumed and the heat produced by storage devices.! Rather than facing the constant installation of new storage devices, the solution must make it possible for the organization to get greater use out of its current storage systems. It must also reduce the ongoing need for additional storage devices.! The solution must drop right into the current IT infrastructure without causing a negative impact on application performance. Applications must, at minimum, perform as they did before.! The solution must reduce the amount of data that is stored and, thus, the time it takes to backup data and support disaster recovery plans. This change must be handled gracefully and not require extensive and expensive changes to storage configurations.! The solution must not force changes in the organization’s processes, procedures or staffing.! Applications and databases, regardless of whether they are supported by physical or virtual servers, should continue to work as before without being re-engineered or re-written.! The ideal solution must be a good neighbor and work with other storage efficiency technologies, such as deduplication.IBM Real-time Compression can address these issues quickly, easilyand without breaking the budget.W H A T IS R E A L -T IM E C O M P R E S S IO N A N D W H YC A N IT H E L P ?Data compression has been a tool IT developers have used to reducethe size of data objects. Traditionally this has been accomplished byencoding data so that it takes up less physical storage.Storage compression methods were based upon finding repeatingpatterns of the zeros and ones that make up a digital file and replacing The Kusnetzky Group © 2011 Page 3
  4. 4. them with a single copy of that pattern and the number of times thatpattern must be repeated when the file is expanded for use.Compression required a great deal of processing power in the past andso was not suitable for general-purpose use. IT developers hadrequirements for data integrity and availability that challenged previousapproaches to data compression. Even with those limitations, It foundstrong proponents in the networking and digital content creationcommunities.Recent improvements in microprocessor performance and datacompression algorithms (Lempel-Ziv) has meant that data compressioncould be accomplished quickly and at a level of reliability to make itpossible to use as a tool for primary storage optimization. IBM’s Real-time Compression Appliances are an example of today’s state-of-the-arttechnology.IBM Real-time Compression Appliances have been designed to improveNAS efficiency dramatically. Here are some of the benefits companiescan realize:! Reduce primary and backup NAS data in real-time by up to 80%, with no performance degradation. IBM’s Real-time Compression Appliances allow NAS data to be handled in compressed form, which leads to improvements in downstream storage system operations (i.e., backup and recovery, archiving, etc.). The less storage to backup and store means faster backup and recovery, increased data availability, better RPO/RTO, and reduced costs. The compression works with NAS data and storage systems and can gain up to 5x more storage efficiency.! Virtual machine files and data produced by virtual environments can also be dramatically reduced in size. In VMware environments, IBM Real-time Compression reduces primary storage by up to 72%.! IBM Real-time Compression enhances data deduplication to improve overall data reduction.! There is a cascading effect of efficiencies - IBM Real-time Compression enables significant reductions in storage CPU and disk utilization and less storage traffic going over the network.! A reduction in the data footprint means less storage equipment to power, cool and manage.! IBM Real-time Compression Appliances are non-disruptive to existing systems, applications, and processes.! IBM Real-time Compression Appliances are easy to install and use.! Improvements across the entire information life cycle can help further reduce management expenses.U S E R S T O R IE SLet’s examine an example of how an IT organization that deployed avirtualization environment found itself facing explosive data growth andthen benefited from the use of IBM’s Real-time Compression inmanaging that growth. BEN-GURION UNIVERSITYBen-Gurion University in Israel is a major center for teaching andresearch, with more than 19,000 students enrolled in the Faculties ofEngineering Sciences, Health Sciences, Natural Sciences, Humanities The Kusnetzky Group © 2011 Page 4

In addition to University programs, select outside researchgroups are permitted to utilize the high performance computingenvironments on campus.Ben-Gurion University uses VMware for server virtualization. CHALLENGEAll groups are added to the University’s main data cluster in order toprovide ongoing access to resources and the capability to utilizeavailable storage resources allocated to other groups at the University.By utilizing a “storage on demand” model that enables researchers, labsand whole departments to acquire managed disk space on an as-neededbasis, Ben-Gurion allows groups to grow over time while ensuring alldata is fully backed up to the University’s backup filer and then archivedto tape. Ben-Gurion was experiencing exponential data storage growthwith an expanding number of research groups, University administrationand academic departments demanding ever-larger amounts of storagecapacity.The department currently has a VMware server farm that runs over 50virtual servers with 1.5TB of disk space each from a centralized NetApp®file server. With data storage demands continuing to grow rapidly, the ITdepartment was looking for a new technology that would improve itsstorage efficiency. It needed a solution that would enable it to utilizeexisting disk capacity more efficiently without affecting performance orcreating an additional layer of management complexity. SOLUTIONBen-Gurion’s IT department deployed IBM Real-time CompressionAppliances to automatically compress Microsoft Office data, researchdata and Oracle databases that are stored on its virtual NAS and Sun®Solaris® solutions. The IT department was able to start compressingdata immediately. All of the data already stored on the University’ssystem was compressed, reducing each existing 300 GB volume to lessthan 50 GB. The reduced size of the volumes made it much moremanageable to perform functions such as mirroring and backup, and theentire storage environment now runs much faster than before.Ben-Gurion realized a 65% to 83% reduction across its Microsoft Officedata, research data and Oracle databases. By compressing homedirectories on-the-fly, IT administrators have been able to create newvolumes and copy over data quickly and easily. All data is seamlesslycompressed and does not require stopping the production environment,making it easier to copy data whenever needed as well as improveoverall system performance.With the ability to seamlessly compress data, without affectingproduction environment performance, the IT department at Ben-GurionUniversity is now able to offer end users additional storage capacity atthe same cost. It also empowers IT managers to better utilize theUniversity’s existing storage solutions.With the additional space savings, the University’s IT department hasbeen able to extend the life-cycle of the current infrastructure without The Kusnetzky Group © 2011 Page 5

The IT department is able to offer research labs and departments more storage capacity at the same cost and extend the lifespan of its current infrastructure despite growing storage requirements. S U M M A R Y Organizations are using more and more data. Much of this growth can be attributed to the increasing collection of analytical data, documents, messages, presentations and other unstructured data. Data retention requirements and the need for both backup and disaster recovery plans is causing organizations to face the fact that backup and disaster recovery procedures are time consuming. As difficult as it is to address the need to maintain backups today, the introduction of virtual servers and virtualized environments is likely to only exacerbate the problem. The proliferation of virtual environments means that there are more sources of data to include in a company’s backup and archival storage plan. Increased requirements for data storage causes a number of painful problems including increased costs, difficulty finding a window of time to successfully backup data, and being prepared for either a disaster or for an audit. Reducing primary NAS data enables companies to address storage efficiency issues at the source of the problem. Real-time compression’s benefits cascade throughout downstream storage operations such as backup, recovery and archiving, as well as optimize the efficiencies of other data reduction technologies such as deduplication. In virtualization environments, real-time compression complements system and storage reduction requirements and contributes to improving the overall cost of running the IT infrastructure by reducing the amount of storage equipment that needs to be powered, cooled and managed. IBM Real- time Compression Appliances are able to affect this high level of storage optimization by up to 5x without performance degradation or forcing the company to change applications, processes, or procedures.
