  • Melbourne Health consolidates 1000 DAT tapes into a single database
    data into one single database and to convert the images from proprietary MRI to DICOM files After initially looking at using the Oracle Database 10g Naomi Rafael senior database administrator at BioGrid was encouraged to beta test version 11g as its more advanced ability to manage DICOM images had the potential to better handle the store of images Rafael s team has since been testing DICOM image storage metadata extraction and DICOM image retrieval with satisfactory results The DICOM datatype as part of the offerings in Oracle 11g were extremely advantageous to the advancement of this project Rafael says The datatype has built in functions such as extraction of the object metadata anonymise function and ability to create views on the DICOM object itself In particular the project team while facing huge data growth in the coming months and years has welcomed the image compression aspects of the new release The database currently represents 45 000 examinations comprising over seven million individual MRI images The compression functionality has yielded 42 compression of the data content Rafael says Furthermore the team is happy with the security features of the solution As Rafael points out they allow the grouping and sharing of multiple patient MRI images between systems without divulging confidential details such as a patient s name or private details The security and compliance elements of Oracle 11g improve on the strict role based regime from the previous version It ensures only the right personnel can access sensitive data Additionally options exist to enable the hospital to audit access history to ensure privacy standards are maintained and that breaches are easily identifiable Dig Deeper on Tape backup All News Problem Solve Family Court of Australia seeks new tape drives sticks with LTO 4 Victoria seeks storage for 25 000 tapes LTO 5 Fast vast but still the past Virtual tape libraries grow up speed up up the ante Load More View All Family Court of Australia seeks new tape drives sticks with LTO 4 Victoria seeks storage for 25 000 tapes LTO 5 Fast vast but still the past Virtual tape libraries grow up speed up up the ante Load More View All News Tape encryption purchases Part Two LTO 4 considerations What you need to know about LTO 4 tape Seven ways to minimise tape failure Calculating MTTF mean time to failure for tape libraries View All Problem solve ADS BY GOOGLE Latest TechTarget resources CIO AU Security AU Data Backup Disaster Recovery SMB Storage Storage Channel Search CIO com au Internet of Things Food safety apps set to emerge Food safety could emerge as a key application for the Internet of Things in the coming months providing real time visibility in Cloud security culture a building block for today s businesses As organizations today move more data to the cloud it s important to cultivate a cloud security culture and enlist a CISO a new How to do an advanced data analytics project on the cheap Delivering an advanced

  • Tape encryption purchases Part One: Essential issues
    Decide where to encrypt Encryption can be implemented through a specific application when data is actually saved such as Oracle though that will only encrypt data for that specific application The broader form of source encryption takes place at the backup server through the backup software such as EMC s Legato Symantec s Veritas NetBackup and IBM s Tivoli Storage Manager Both types of source encryption can impair its server s performance since encryption is CPU intensive Data can also be encrypted at the media itself For example LTO 4 tape drives incorporate AES 256 bit encryption This eases any performance impact on backup jobs and provides protected tapes that can be sent offsite Finally data can be encrypted in flight using a dedicated security appliance such as Decru s DataFort the StrongBox SecurDB from Crossroads Systems or the CryptoStor family from NeoScale Systems While dedicated appliances can be more expensive than software only solutions they typically offer superior performance by encrypting decrypting data at line speed imposing little if any performance penalty Determine the impact of encryption on compression Compression works by removing redundant elements of information from a data stream Encryption however effectively randomises the data stream and removes all redundancy If you implement encryption prior to compression you will lose the compression feature in your drives or backup software You then need more media to complete the backup or time to transfer across the wire Increased media requirements will raise the cost and maintenance burden of any backup processes Reducing the amount of compressed data e g encrypting only selected data can mitigate this issue but implementing encryption after the compression process can also help Remember that encryption can affect performance Encryption is a mathematical process and when implemented in software can demand significant processing power from the host server This in turn can affect performance Experts suggest that the penalty for software based encryption products can reach 40 50 depending on the type of encryption and the files being protected By comparison a dedicated hardware encryption box might only impair performance by 10 or less This means that encryption will take longer to process backups or conduct remote data transfers posing a dilemma for storage administrators who already struggle with bloated backup windows and WAN bandwidth limitations Most storage professionals resolve this quandary by encrypting only the most sensitive data Consider the implications of encryption key management All encryption requires the use of a unique key which seeds the encryption algorithm The key is also needed to decrypt the data later on when files are read from tapes or disks encrypted data is effectively unreadable without the key Companies must impose strict controls and policies such as key quorums to ensure that only responsible storage professionals have access to the key NEXT Specific LTO 4 tape issues Dig Deeper on Tape backup All News Problem Solve Family Court of Australia seeks new tape drives sticks with LTO 4 Victoria seeks storage for 25 000 tapes LTO

  • Tape and disk encryption product roundup
    could potentially be accessed by an unauthorized person says W Curtis Preston vice president of data protection at GlassHouse Technologies I wouldn t use it where the cost significantly outweighs the risk Once you identify the data that needs encryption it s important to define where the encryption will be implemented Encryption can be used to protect data in flight across a network and at rest on a hard drive or tape in the data center Protecting data in flight is particularly important when corporate data must be transmitted over open or unsecured networks such as the Internet Protecting data at rest is a more recent consideration and is typically applied to tape backups that are sent off site However an increasing number of corporations will also opt to encrypt data on disk in the data center to guard against data loss from hackers or employee theft Although encryption works the same way on any target media including hard drives optical disc and tape it s important to consider the implications of encryption on tape compression Encrypted data by its nature cannot be compressed Preston says For example if you receive an average of 2 1 compression on a 10 gigabytes GB tape you can fit up to 20 GB of data on the tape If the data is encrypted first and is uncompressible you ll need to use two 10 GB tapes doubling your tape media costs To avoid this potential problem implement encryption after compression Encryption is a mathematically intensive process and can have a negative impact on the performance of your network depending on the type of encryption the way it is implemented and the amount of files being protected Strong encryption such as AES 256 is more intensive than other weaker forms of encryption More data takes more time to encrypt And of course software encryption products also take much more of a performance hit than hardware based products Analysts note that software encryption can impose a 40 50 performance hit on your network By comparison a hardware encryption box might only impair performance by 10 or less The trick is to find a product that meets your needs with a minimum performance penalty For example suppose you only need to encrypt a single database A software encryption tool might only cost about 500 while the extra few minutes needed to encrypt the database and the extra storage space for that uncompressed file on tape might barely be noticeable When encrypting the entire data center however it probably makes more sense to use encryption hardware to minimize the performance penalty across a huge volume of data even though you will have to spend about 30 000 per box Finally any move to encryption must involve a close examination of key management Lost keys can render corporate data inaccessible so a potential adopter must learn how encryption keys are held or maintained and understand the risk involved The risk is that you lose your key Preston says

  • The importance of data migration in storage tiering
    to think about what to optimize Look at understanding your data and figuring out how you want to work with the data set optimize it and tier it It s not that hard of a question but it s pretty challenging to look at that data and figure out what s there You can look at a number of file classification tools to understand file storage or even just performance for different sets of data Make some decisions about where you want to put that data based on different parameters with this idea of optimizing storage efficiency in mind There might be some other reasons to optimize storage too so this is more than just an IT exercise When you get into this with a big company you need to look at collaborative names that can represent some of the different business data owners in the enterprise and look at aligning tiering processes for each type of data with some of the service levels that you plan on delivering back to those business owners So you may have low performance requirements with a critical data set but they might require the level of protection that you re going to apply only to your top tier of storage This is a pretty complex web and there needs to be a collaborative team process The efficiencies you can get from tiering your storage are pretty tremendous and can be justified at cross disciplinary cross business owner exercises at most companies It is really a matter of getting the right people at the table so you can understand your data beyond what just a classification tool would give you So there are two dimensions to understanding what they are understanding what the data actually is and who owns it and then understanding what it is from the business owners as well Tiered storage allows an organization to optimize its data storage infrastructure to lower costs increase performance and address capacity issues However an organization should look to optimize its data migration strategy as it will play an important role in the end result of a tiered storage strategy In this interview Jeff Boles senior analyst and director validation services at analyst firm Taneja Group examines some of the business drivers behind storage tiering He also explores some of the challenges associated with tiered storage such as data migration and how effectively addressing these challenges can be the key to tiered storage success SearchStorage What are the possibilities for getting into tiered storage and why would an organization want to Boles The concept of tiered storage has been around for awhile going back to the days of HSM Hierarchical Storage Management But around file storage today with the runaway capacity requirements and escalating performance demands most of us are facing it makes a lot of sense to tier storage for efficiency reasons If you can get the right storage in the right place you can tweak the way you manage your storage between tiers and optimize your management resources For data backup you might be able to if you take fairly stale data and park it off to the side where you have to manage it less often optimize your backup processes for primary storage and trim the time and effort you re spending on managing backups That goes for every dimension of storage management whether it s capacity or performance management Tiered storage can increase your overall efficiency and optimize operational expenditures but it s also a capital expenditure exercise If you tier your storage you can buy lower cost higher capacity stuff to handle archival data for nearline storage with your lesser used data You want to get into tiering to optimize your storage especially in the face of runaway capacity because there s too much to keep up with if you re not looking for a better approach than just adding more NAS units SearchStorage What are some of the challenges associated with tiered storage Boles There are a whole bunch of challenges out there when you re first moving into tiered storage and some of them are architectural how you want to go about implementing tiered storage in your infrastructure Thinning out different tiers of storage is simple but figuring out how you re going to migrate data and keep it there for the long term is pretty challenging because there are a bunch of options on the market You can apply inline appliances like F5 Networks Inc s Acopia switches You can apply out of band solutions that migrate data in the off hours or with an engine that s out of band from your storage You can choose to use a solution that integrates with vendor specific APIs like file policies and redirects from primary storage to nearline or archival storage Or you can use things like stub files There are a bunch of choices on the market and a lot of them are architectural Moreover those choices involve emerging technologies like cloud storage or solid state drives SSDs that might be able to cache and offset some of the performance requirements But it s really a matter of choosing how you re going to get data there how you re going to access data when it s there and how you re going to manage it for the long term how you re going to migrate this storage after you ve tiered it Data migration comes down to looking at engines with the right features whether you want to have an inline solution that sits on your NAS infrastructure and moves data for you or you want the engine off to the side Whether you want the engine to be constantly or periodically operating or whether you want to administrate your involvement with it or use a set of policies to always manage data migration The second dimension is how you re going to access the data Do you want to access it through stub files There

  • Document management softwares stake a claim for tiering duties
    or MP3 files as likely escapees from such applications Document management systems are also incapable of addressing documents they do not manage and do not concern themselves with other data management tasks like backup and maintenance of archives He therefore advocates storage management software as the most logical tool with which to tier as they not only offer greater coverage but also offer more efficient and secure means of data storage by leveraging technologies such as compression deduplication single instance storage and encryption McClure concludes that The best approach is to select an archiving vendor that provides integration with document management systems allowing for the data in the archive to be available on demand searchable and if relevant declared as a record into a document management system Paul Lancaster Director of Systems Engineering Symantec also has issues with document management driven tiering which he says may claim to do some tiering but ultimately this requires an organisation to make changes to business processes which can be difficult to implement However if we look at the management side from an application owner document management may be able to put in place prerequisites that are purely limited to the document management applications If document management is in charge of tiering organisations will probably have to redesign the associated applications and there would also then be a need for associated changes in the methods of data protection Lancaster instead advocates tiering at file level because the interrogation files it requires creates metadata that allows tiering to be applied to data beyond the document management system He also points out that Symantec can tier data at the moment of its creation saving the need for later classification and movement Co existence is possible But hardware vendors are also happy to co exist with other tiering players Adrian De Luca Hitachi Data Systems Director Pre Sales Solutions for Australia and New Zealand says there can be synergies doing it in both layers of the stack The advantage of implementing tiering at the software or application level means the policies for moving the data between tiers can be very sophisticated since it based on rich metadata associated with the content This is great if you want to implement an archiving policy for retention purposes However the downside is that you will need to create policies for each application which can become complex and end up being a management nightmare Storage vendors on the other hand can implement tiering at the volume block or file level which can address solve a number of other problems For example if a critical application requires more performance promoting the data volumes from tier 3 to tier 1 non disruptively can provide immediate relief Some storage technologies can move individual blocks from a volume this is particularly useful if you have any hot areas being accessed frequently to improve transaction times File servers are a perfect candidate for tiering due to the rich nature and value of the files they hold
