Each technology came with the promise that by implementing the new capability, IT would save money. Storage is one area within IT where costs are rising, driven by 50% year-over-year data growth, and where deploying the right innovation can save more than 50% of the IT budget. This section is a technology deep dive into the dilemma created by the 20% annual growth of traditional disk drives in data centers combined with only 10% growth in the rate that data can take data off a disk is only growing by about 10%. The concept behind the Flape architecture is to place the most active data as well as the metadata (the data about the data) on flash and the rest of the (cold) data on tape. The first issue is with the HDD disk manufacturers themselves and the second is the disruption to the HDD business caused by flash.
Disk bandwidth is improving at the CGR of disk linear density = v Areal Density CGR of 20% = 9.6%. This formula tells us that as HDDs grow in capacity, getting data off them becomes more difficult. Of course, not all data should be stored on SSD since it is too expensive especially given the value of data over time. Enterprise Tape is 100,000 times more reliable than consumer disk (see Table 1 in Footnotes) with greater longevity. This tells us that the ability to get data off tape is getting faster, relatively, given the tape growth rates. Figure 5 shows application spaces as a function of "time-to-first-byte" and "time-to-last-byte". By leveraging LTFS and integrating it as a part of the data lifecycle, businesses have the ability to make sure they are achieving one core metric: storing data of lower business value on the lowest cost storage medium possible.
LTFS is typically implemented where data tapes are written in the LTFS format and can be used independently of any external database or storage system, allowing direct access to file content data and file metadata. Another important aspect of LTFS is that it has a very simple and smart pricing model (implemented by most vendors). One way IT is solving the “time to first byte” challenge is by leveraging flash to manage the metadata of the data that is on tape, making tape even more effective. Figure 5 above shows examples of how to leverage flash, disk and tape technologies to meet specific business requirements.
The concept of flape is very real, and a number of customers have deployed the combination of flash and tape in their environments today.
The other thing to keep in mind about a flape infrastructure is that a lot of the common “storage services” that are available today for storage arrays just aren’t available for tape. The overall architecture lends itself to a few characteristics that support these use cases very well.
Lastly, tape file systems based on industry standards allow ISVs to write to these platforms, making it much easier to utilize new capabilities where there is no standard for deduplication. Some of the objections to tape and flape come from a misunderstanding and misapplication of the technology. There is a huge difference between the optimal structure for backups and the optimal structure for long-term retention. The "missing links" in designing flape systems are the file and meta-data systems that will support this environment. Some companies that Wikibon interviewed have developed their own "flape" solutions to this problem, such as in the media library area. Wikibon recommends that CIOs and CTOs seriously consider flape architectures to reduce the cost of long-term retention of data and as a fundamental way to enable the business to turn unmanageable data into a true business asset. David, I do love "flape", and you make strong arguments for greatly increased use of integrated "live" tape storage (as opposed to off-site data archiving).

Only the years up until your state pension age will count - even if you defer getting your pension.3. You can pay voluntary National Insurance Contributions in order to bring you up to 10 years - or to the maximum of 35.
If you have been in a contracted out final salary scheme, you will have paid lower NI contributions. Team Group's all new SD 4.0 microSDXC UHS-II U3 is continuing adopting Color Card's advanced heat transfer color inkjet printing technology.
Less than 90 day reservations for peak season (January-March) can call for short term availability starting September 15th. Deposits of $500.00 or more may be carried over to your next reservation, if cancelled 90 days prior of your arrival date, but must be used within a year.
This changes the dynamics of storage for long-term data retention and so-called big data lakes. In particular, the tape industry has been slow to capitalize on technology progressions and its marketing has been weak.
The issue is that a large percentage of the overall IT budget is consumed in order to maintain the status quo with little to no dollars being spent on innovation or new capabilities that drive business growth and shareholder value. In many instances, these technologies did help a specific segment of the infrastructure but may have hurt others.
Several new storage technologies have come on the market with the promise of saving IT money.
The combination of flash and tape provides IT with the right balance of performance and cost for a number of use cases. However, because of flash technologies driven by the consumer market, the market for disk drives on PCs has gone to hell in a hand-basket.
Today's maximum rotation is 15,000 RPM, but the most cost-effective speed for capacity is 7,200 RPM, with little prospect of increasing.
The reality is that HDDs cannot spin any faster, no more heads can be put on an HDD, nor can more platters be added to an HDD (at least under current design constraints).
It is portable, its areal density is growing faster, and vendors are making significant investment it tape today, more than into HDDs.
And the areal density is growing at approximately 30% versus disk, which is growing at only 9.6%.
This is an important concept and makes a difference when architecting a Flape infrastructure to meet performance requirements.
Today, LTFS is an open, self-describing tape format that allows tape to look like a file system. LTFS sits beside a disk-based file system and, based on the policies of the data, typically when usage becomes low, the data is migrated to LTFS. While a company works on files that are a part of a movie, this data lives on active storage (HDD or SSD). The bandwidth comes from increased linear density and increased number of heads across the tape - hence 30% improvement in tape bandwidth.
The strong investment by consumer technologies in flash is driving density, and therefore also bandwidth, improvement at 43%.
Over time, we believe a variety of different ISVs, vendors or even partners will develop software and tools that live on top of the flape (with LTFS) solution, enabling users to get at the data faster. Wikibon believes that as the software-led data center and software-led storage become more commonplace, these storage service capabilities will be available to all devices in the infrastructure and offered in a common way that provides seamless data management across the enterprise. By taking advantage of the tape layer, use cases like archiving, long-term retention and tiered storage (where 70+% of the data is stale) can live on a low-cost storage medium like tape. Deduplication arrays make adoption of those capabilities more difficult and introduces inflexibility into the environment. For example, disk-based de-duplication systems such as Data Domain from EMC and StoreOnce from HP have been very successful in solving the problems of rapid recovery from backup. Both may include compression and de-duplication, but the fundamental access methods, access requirements and metadata to support (for example) compliance and provenance are completely different.
Oracle is investing in this area, with a long history of innovation in tape and tape libraries. I have a question about HDDs vs LTOs: why is the HDD bandwidth speed shown in Figure 4 so low? However, as with everything in the world of pensions, if you're going to really understand what it means for you, you need to go past the simple headline to the slightly more complex truth. If you have fewer than ten years of contributions then you won't get any state pension at all.
You'll need to defer for a minimum of nine weeks, and in return for each nine week period you will get another 1%. You need to do this before you retire, and you need to make sure you are credited with your contributions for the years when you were caring for children, unemployed or sick.5. If you contracted out and saved into a personal pension, your NI contributions will have gone into a private pension. You will get a letter three months before your state pension age letting you know how to claim. Once it has equalised with men, the state pension age for men and women will rise together.

With the latest technology in ecofriendly inks, carbon emissions can be greatly reduced and completely fulfill the concept of "memory last forever".
The key to this approach will be surfacing metadata, currently buried on tape cartridges, to a flash layer that can signal the location of desired data on the tape.
Tape vendors must seize this opportunity by creating flash-based systems, positioning them for long-term data retention and making tape relevant to the future of enterprise IT. New technologies and capabilities are unveiled every year that tout their economic value in order to get CIOs to pick their heads up from their smart phones to make a purchasing decision. At the end of the day, very few of these new capabilities actually put IT departments in a position to change their investment strategy to focus on innovation. Feel free to skip ahead to the next section if you already understand the fundamentals of this problem. Before we get into details, let’s discuss why Wikibon believes this combination of technologies can have a profound impact on storage budgets, and on the overall storage market. Smaller disks could spin faster, but no one is investing in new disk technologies to accomplish this. Low cost HDD isn't the answer - we just stated that capacity utilization, environmentals and operational costs, especially for large data sets, are extremely high considering how this data will be used. The next question is whether tape can achieve the performance required to meet the business objectives.
The advent of LTFS has added the benefit of simplicity to tape, making it easier to use and leverage and making it more ubiquitous and accessible for a broader audience. As the movie is produced and released, the data that makes up the movie is then migrated to lower cost storage, tape, via LTFS. The software is not licensed by the terabyte, which tends to be a big challenge for customers.
It not only meets the performance needs of today, but will grow and scale into the future, saving the business money in the long term.
At the end of the day, flash is getting faster and less expensive, tape is getting faster and is inexpensive and HDDs are not getting that much faster and based on how they need to be used in order to store data effectively, with RAID etc., are very costly. First, while a number of ISVs have worked with various vendors to integrate their software to work more seamlessly with LTFS, more work needs to be done.
With advancements to LTFS need to grow by supplying RESTful APIs such that these new middleware layers can have better access to the data.
For many organizations, backup has been used as a type of archive and method of last resort for recovering data. Using a backup structure for long-term retention is not a strategic option for allowing access to and mining of long-term data that is infrequently accessed.
Other areas such as storing very large problem datasets in simulation and oil exploration already have tape solutions well established. Magnetic media will continue to be the low cost method for holding data for the foreseeable future. As shown in Figure 1 above, flape solutions can enable IT to turn unmanageable, infrequently accessed "big data" into a true business asset. However, this is far less generous than the old bonus for deferring, so consider carefully if it's worth it to you.4. With the included free SD 4.0 UHS-II SD card adapter, consumers are allowed to freely use on digital cameras, dashboard cameras, cell phones and various other devices, and offers the perfect balance in performance and usefulness. It is the best storage medium which offers higher resolution, higher frames per second and higher data streaming rates for Full HD or even breathtaking Ultra HD 4K quality.
Combined with linear tape file system technology, we believe this approach will deliver better business value for the right use cases. A few examples are server virtualization, data deduplication, and now converged infrastructure solutions.
In theory you could increase the number of heads by having more arms - but there is no investment there either. The formulas above prove that getting data off tape is faster than getting it off disk, with one caveat.
For straight file system data moves based on simple policies, such as age of a file or last touched data, the standard LTFS implementation fits most needs. Deduplication arrays do a good job for solutions with a great deal of redundant data being added day-after-day such as operational backup, but for the longer term storage and scale, tape is unmatched. The argument goes that backup appliances should be the model for long term retention, as the data is already stored in the backup and therefore will not take any more space if the backup system is expanded to include long-term retention. Future designers of Server SAN software as part of software-led infrastructure should include tape and tape libraries as media alternatives. Disk will continue to be an important part of a storage hierarchy, especially for legacy systems and new systems where small objects are needed infrequently but quickly.
I assume that it is because you talk of sustainable bandwidth, is it because you assume a fully fragmented disk? In addition, new rules mean you cannot inherit your partner's state pension entitlement any more - except in very limited circumstances.7. You just pay your first two month's rental payments, which are based on the price of the model and size you select.
Once you “get to” the first byte of data, tape is faster, but getting to that first byte is the trick.
So when “part 2” of the movie is being worked on, video editors can easily and quickly grab data from the first movie that they may want to use in the second, perhaps for a flashback.
A unit price for the software ensures that software and maintenance costs don’t grow, which helps to keep long-term data retention costs low over time. In each case, both solutions are simple and easy to manage, provide much higher utilization capabilities, and much lower environmental costs, all which save money and free up time for IT to work on project that drive innovation. However, if there are other parameters then a flape environment may be trickier to implement. Deduplication arrays are more expensive since the software to drive the deduplication costs a premium and data migration and the multiple systems required due to scale issues end up costing even more. Future developers of archive, backup and Big Data systems should allow for higher performance and lower cost systems by utilizing flape. Vendors who claim that either tape or disk is dead are doing a disservice to their customers.
If getting to that first byte means you need to go get the tape, mount the tape into the library and index the tape before you can begin looking for the data, then yes, disk is faster because the time to the first byte is faster. As a tape environment grows, the only real growth challenges are the number of tapes for capacity purposes and perhaps the number of libraries, which allow control over the “time to first” byte characteristic by keeping more tapes in the library. One example is a media company whose value-added is in managing the metadata to perform life cycle management of its customers' media data.
The location you select must be accessible at all times by a truck and trailer for delivery, and during your Rental Contract. However, if the tape is in the library, mounted and indexed, then the time to first byte is greatly reduced.
LTFS changes the dynamic from application or device performance to true work performance which, in this case, has real business value. It has a cloud-based solution to support a majority of its customers who want to monetize their video assets or otherwise preserve those assets for foreseeable or unforeseeable purposes. So the new active day say from the company ERP system will reside in flash and inactive data on tape, but what then happens when you want to move more data from flash to tape? After 36 on time payments, you will own your unit and will receive a Certificate of Ownership.
The media company is required to always have two copies of the content and provide this data over the cloud. Its tool provides the content owner with the ability to identify and pull out subsections of a 20TB movie file in order to create a 30 sec promo. It ended up building its own metadata manager that lived on top of LTFS that allowed it to find data inside millions of movie files. You are not required to keep the building if your building becomes a financial burden, or for any reason you no longer need the building. There must be clear access to the delivery location, and the lot should be no more than 30" out of level.
