Last week, I presented IBM's strategic initiative, the IBM Information Infrastructure, which is part of IBM's New Enterprise Data Center vision. This week, I will try to get around to talking about some of theproducts that support those solutions.
I was going to set the record straight on a variety of misunderstandings, rumors or speculations, but I think most have been taken care of already. IBM blogger BarryW covered the fact that SVC now supports XIV storage systems, in his post[SVC and XIV],and addressed some of the FUD already. Here was my list:
Now that IBM has an IBM-branded model of XIV, IBM will discontinue (insert another product here)
I had seen speculation that XIV meant the demise of the N series, the DS8000 or IBM's partnership with LSI.However, the launch reminded people that IBM announced a new release of DS8000 features, new models of N series N6000,and the new DS5000 disk, so that squashes those rumors.
IBM XIV is a (insert tier level here) product
While there seems to be no industry-standard or agreement for what a tier-1, tier-2 or tier-3 disk system is, there seemed to be a lot of argument over what pigeon-hole category to put IBM XIV in. No question many people want tier-1 performance and functionality at tier-2 prices, and perhaps IBM XIV is a good step at giving them this. In some circles, tier-1 means support for System z mainframes. The XIV does not have traditional z/OS CKD volume support, but Linux on System z partitions or guests can attach to XIV via SAN Volume Controller (SVC), or through NFS protocol as part of the Scale-Out File Services (SoFS) implementation.
Whenever any radicalgame-changing technology comes along, competitors with last century's products and architectures want to frame the discussion that it is just yet another storage system. IBM plans to update its Disk Magic and otherplanning/modeling tools to help people determine which workloads would be a good fit with XIV.
IBM XIV lacks (insert missing feature here) in the current release
I am glad to see that the accusations that XIV had unprotected, unmirrored cache were retracted. XIV mirrors all writes in the cache of two separate modules, with ECC protection. XIV allows concurrent code loadfor bug fixes to the software. XIV offers many of the features that people enjoy in other disksystems, such as thin provisioning, writeable snapshots, remote disk mirroring, and so on.IBM XIV can be part of a bigger solution, either through SVC, SoFS or GMAS that provide thebusiness value customers are looking for.
IBM XIV uses (insert block mirroring here) and is not as efficient for capacity utilization
It is interesting that this came from a competitor that still recommends RAID-1 or RAID-10 for itsCLARiiON and DMX products.On the IBM XIV, each 1MB chunk is written on two different disks in different modules. When disks wereexpensive, how much usable space for a given set of HDD was worthy of argument. Today, we sell you abig black box, with 79TB usable, for (insert dollar figure here). For those who feel 79TB istoo big to swallow all at once, IBM offers "capacity on demand" pricing, where you can pay initially for as littleas 22TB, but get all the performance, usability, functionality and advanced availability of the full box.
IBM XIV consumes (insert number of Watts here) of energy
For every disk system, a portion of the energy is consumed by the number of hard disk drives (HDD) andthe remainder to UPS, power conversion, processors and cache memory consumption. Again, the XIV is a bigblack box, and you can compare the 8.4 KW of this high-performance, low-cost storage one-frame system with thewattage consumed by competitive two-frame (sometimes called two-bay) systems, if you are willing to take some trade-offs. To getcomparable performance and hot-spot avoidance, competitors may need to over-provision or use faster, energy-consuming FC drives, and offer additional software to monitor and re-balance workloads across RAID ranks.To get comparable availability, competitors may need to drop from RAID-5 down to either RAID-1 or RAID-6.To get comparable usability, competitors may need more storage infrastructure management software to hide theinherent complexity of their multi-RAID design.
Of course, if energy consumption is a major concern for you, XIV can be part of IBM's many blended disk-and-tapesolutions. When it comes to being green, you can't get any greener storage than tape! Blended disk-and-tapesolutions help get the best of both worlds.
Well, I am glad I could help set the record straight. Let me know what other products people you would like me to focus on next.
Continuing this week's theme about new products that were mentioned in last week's launch, today I willcover the new [S24 and S54 frames].
Before these new frames, customers had two choices for their tape cartridges: keep them in an automatedtape library, or on an external shelf. Most of the critics of tape focus almost entirely on the problemsrelated to the latter. When tapes are placed outside of automation, you need human intervention to findand fetch the tapes, tapes can be misplaced or misfiled, tapes can be dropped, tapes can get liquids spilledon them, and so on. These problems just don't happen when stored in automated tape libraries.
Until now, the number of cartridges were limited to the surface area of the wall accessible by the roboticpicker. Whether the robot rotates in a circle picking from dodecagon walls, or back and forth from longrectangular walls, the problem was the same.
But what about tapes that may not need to be readily accessible, but still automated? With the newhigh density frames, you can now stack tapes several cartridges deep, spring loaded deep shelves thatpush the tape cartridges up to the front one at a time. The high-density frame design might have been inspired by thefamous [Pez] candy dispenser, but at 70.9 inches, does not beat the[World's Tallest Pez Dispenser].
(Note: PEZ® is a registered trademark of Pez Candy, Inc.)
In a regular cartridge-only frame, like the D23, you have slots for 200 cartridges on the left, and 200 cartridges on the right, and the robotic picker can pull out and push back cartridges into any of theseslot positions. In the new S24, there are still 200 slots on the left, now referred to as "tier 0",but up to 800 cartridges on the right. In each slot there are up to four 3592 cartridges, the positionimmediately reachable to the picker is referred to as "tier 1", and the ones tucked behindare "tier 2", "tier 3" and "tier 4".
<- - - S24 frame - - - >
We have fun slow-motion videos we show customers on how these work. For example, in the diagram above, let'ssuppose you want to fetch Tape E in the "tier 4" position. The following sequence happens:
Robotic picker pulls "tier 1" tape cartridge B, and pushes it into another shelf slot. Tapes C, D and E get pushed up to be Tiers 1, 2 and 3 now.
Robotic picker pulls "tier 1" tape cartridge C, and puts it in another shelf slot. Tapes D and E get pushed up to be Tiers 1 and 2 now.
Robotic picker pulls "tier 1" tape cartridge D, and puts it in another shelf slot. Tape E gets pushed up to be Tier 1 now.
Robotic picker pulls "tier 1" tape cartridge E, this is the tape we wanted, and can move it to the drive.
The other three cartridges (B, C and D) are then pulled out of the temporary slot, and pushed back into their original order.
In this manner, the most recently referenced tape cartridges will be immediately accessible, and the ones leastreferenced will eventually migrate to the deeper tiers. The 3592 cartridges can be used with either TS1120 orTS1130 drives. Each cartridge can hold up to 3TB of data (1TB raw, at 3:1 compression), so the entire framecould hold 3PB in just 10 square feet of floor space. Five D23 frames could be consolidated down to two S24 frames.The S24 frame comes in "Capacity on Demand" pricing options. The base model of the S24 has just tiers 0, 1 and 2, for a total capacity of 600 cartridges. You can then later license tiers 3 and 4 when needed.
The S54 is basically similar in operation, but for LTO cartridges. It works with any mix of LTO-1, LTO-2, LTO-3 andLTO-4 cartridges.The left side holds tier 0 as before, but the right side has up to five LTO cartridges deep. For Capacity on Demand pricing,the base model supports 660 cartridges (tiers 0,1,2), with options to upgrade for the additional 660 cartridges.The total 1320 cartridges could hold up to 2.1 PB of data (at 2:1 compression). One S54 frame could replacethree traditional S53 frames that held only 440 LTO cartridges each.
If you have both TS1100 series and LTO drives in your TS3500 tape library, then you can haveboth S24 and S54 frames side by side.
Well, it's Tuesday again, which means IBM announcement day. With our [big launches] we had this year, there might be some confusion on IBM terminology on how announcements are handled.Basically, there are three levels:
Technology demonstrations show IBM's leadership, innovation and investment direction, without having to detail a specificproduct offering.Last month's[Project Quicksilver], for example, demonstrated the ability to handle over 1 million IOPS with Solid State Disk.IBM is committed to develop solid state storage to create real-world uses across a broad range of applications, middleware, and systems offerings.
A preview announcement does entail a specific product offering, but may not necessarily include pricing, packagingor specific availability dates.
An announcement also entails a specific product offering, and does include pricing, packaging and specific availability dates.
With our September 8 launch of the IBM Information Infrastructure strategic initiative, there were a mix of all three of these. Many of the preview announcements will be followed up with full announcements later this year. Today, the IBM Tivoli Advanced Backup andRecovery for z/OS v2.1 was announced.
Note: If you don't use z/OS on a System z mainframe, you can stop reading now.
As many of my loyal readers know, I was lead architect for DFSMS until 2001, and so functions related to DFSMS and z/OS are very near and dear to my heart. For Business Continuity, IBM created Aggregate Backup andRecovery Support (ABARS) as part of the DFSMShsm component. This feature created a self-contained backupimage from data that could be either on disk or tape, including migrated data. In the event of a disaster,an ABARS backup image can be used to bring back just the exact programs and data needed for a specific application, speeding up the recovery process, and allowing BC/DR plans to prioritize what is most important.
To help manage ABARS, IBM has partnered with [Mainstar Software Corporation]to offer a product that helps before, during and after the ABARS processing.
ABARS requires the storage admin to have a "selection list" of data sets to process as an aggregate.IBM Tivoli Advanced Backup and Recovery for z/OS includes Mainstar® ASAP™ to help identify the appropriatedata sets for specific applications, using information from job schedulers, JCL, and SMF records.
ABARS has two simple commands: ABACKUP to produce the backup image, and ARECOVER to recover it. However, ifyou have hundreds of aggregates, and each aggregate has several backups, you may need some help identifyingwhich image to recover from.IBM Tivoli Advanced Backup and Recovery for z/OS includes Mainstar® ABARS Manager™ to present a list ofinformation, making it easy to choose from. To help prep the ICF Catalogs, there is a CATSCRUB feature for either"empty" or "full" catalog recovery at the recovery site.
The fact that storage admins may not be intimately familiar with the applications they are backing up is a commonsource of human error. IBM Tivoli Advanced Backup and Recovery for z/OS includes Mainstar® All/Star™ to help validate that the data setsprocessed by ABACKUP are complete, to support any regulatory audit or application team verification.This critical data tracking/inventory reporting not only identifies what isn't backed up, so you can ensure that you are not missing critical data, but also can identify which data sets are being backed up multiple times by more than one utility, so you can reduce the occurrence of redundant backups.
With v2.1 of Tivoli Advanced Backup and Recovery for z/OS, IBM has integrated Tivoli Enterprise Portal (TEP)support. This allows you to access these functions through IBM Tivoli Monitor v6 GUI on a Linux, UNIX or Windowsworkstation. IBM Tivoli Monitor has full support to integrate Web 2.0, multi-media and frames. This meansthat any other product that can be rendered in a browser can be embedded and supported with launch-in-contextcapability.
(If you have not separately purchased a license to IBM Tivoli Monitoring V6.2, don't worry, you can obtainthe TEP-based function by acquiring a no-charge, limited use license to IBM Tivoli MonitoringServices on z/OS, V6.2.)
In addition to supporting IBM's many DFSMS backup methods, from ABARS to IDCAMS to IEBGENER, IBM Tivoli Advanced Backup and Recovery v2.1 can also support third-party products from Innovation Data Processing and Computer Associates.
As many people re-discover the mainframe as the cost-effective platform that it has always been, migratingapplications back to the mainframe to reduce costs, they need solutions that work across both mainframe anddistributed systems during this transition. IBM Tivoli Advanced Backup and Recovery for z/OS can help.
Continuing this week's theme on customer references of IBM's solutions, today I will discussthe success at Kantana Animation Studios.
Here is a 3-minute video from the good folks at Kantana Animation Studios,part of the [Kantana Group].They produced the animated movie [Khan Kluay]using IBM Scale-out File Services (SoFS), a product IBM announced last November 2007.
As a film-maker myself (see this sample [Highlights clip])and active member of the Tucson Film Society,I am pleased to see IBM so greatly involved in the film industry. I've had the pleasure to visit some of theseanimation studios myself and meet with other film-makers at various conferences.
For more details on Kantana's implementation, see the [Case Study]
Earlier this year, IBM launched its[New Enterprise Data Center vision]. The average data center was built 10-15 years ago,at a time when the World Wide Web was still in its infancy, some companies were deploying their first storage areanetwork (SAN) and email system, and if you asked anyone what "Google" was, they might tell you it was ["a one followed by a hundred zeros"]!
Full disclosure: Google, the company, justcelebrated its [10th anniversary] yesterday, and IBM has partnered with Google on a varietyof exciting projects. I am employed by IBM, and own stock in both companies.
In just the last five years, we saw a rapid growth in information, fueled by Web 2.0 social media, email, mobile hand-held devices, and the convergenceof digital technologies that blurs the lines between communications, entertainment and business information. This explosion in information is not just "more of the same", but rather a dramatic shift from predominantly databases for online transaction processing to mostly unstructured content. IT departments are no longer just the"back office" recording financial transactions for accountants, but now also take on a more active "front office" role. For a growing number of industries, information technology plays a pivotal role in generating revenue, making smarter business decisions, and providing better customer service.
IBM felt a new IT model was needed to address this changing landscape, so IBM's New Enterprise Data Center vision has these five key strategic initiatives:
Highly virtualized resources
Business-driven Service Management
Green, Efficient, Optimized facilities
In February, IBM announced new products and features to support the first two initiatives, including the highlyvirtualized capability of the IBM z10 EC mainframe, and and related business resiliency features of the [IBM System Storage DS8000 Turbo] disk system.
In May, IBM launched its Service Management strategic initiative at the Pulse 2008 conference. I was there in Orlando, Florida at the Swan and Dolphin resort to present to clients. You can read my three posts:[Day 1; Day 2 Main Tent; Day 2 Breakout sessions].
In June, IBM launched its fourth strategic initiative "Green, Efficient and Optimized Facilities" with [Project BigGreen 2.0], which included the Space-Efficient Volume (SEV) and Space-Efficient FlashCopy (SEFC) capabilitiesof the IBM System Storage SAN Volume Controller (SVC) 4.3 release. Fellow blogger and IBM master inventor Barry Whyte (BarryW) has three posts on his blog about this:[SVC 4.3.0Overview; SEV and SEFCdetail; Virtual Disk Mirroring and More]
Some have speculated that the IBM System Storage team seemed to be on vacation the past two months, with few pressreleases and little or no fanfare about our July and August announcements, and not responding directly to critics and FUD in the blogosphere.It was because we were holding them all for today's launch, taking our cue from a famous perfume commercial:
"If you want to capture someone's attention -- whisper."
My team and I were actually quite busy at the [IBM Tucson Executive Briefing Center]. In between doing our regular job talking to excited prospects and clients,we trained sales reps and IBM Business Partners, wrote certification exams, and updated marketing collateral. Fortunately, competitors stopped promotingtheir own products to discuss and demonstrate why they are so scared of what IBM is planning.The fear was well justified. Even a few journalists helped raise the word-of-mouth buzz and excitement level. A big kiss to Beth Pariseau for her article in [SearchStorage.com]!
(Last week we broke radio silence to promote our technology demonstration of 1 million IOPS using Solid StateDisk, just to get the huge IBM marketing machine oiled up and ready for today)
Today, IBM General Manager Andy Monshaw launchedthe fifth strategic initiative, [IBM Information Infrastructure], at the[IBM Storage and Storage Networking Symposium] in Montpellier, France. Montpellier is one of the six locations of our New Enterprise Data Center Leadership Centers launched today. The other five are Poughkeepsie, Gaithersburg, Dallas, Mainz and Boebligen, with more planned for 2009.
Although IBM has been using the term "information infrastructure" for more than 30 years, it might be helpful to define it for you readers:
“An information infrastructure comprises the storage, networks, software, and servers integrated and optimized to securely deliver information to the business.”
In other words, it's all the "stuff" that delivers information from the magnetic surface recording of the disk ortape media to the eyes and ears of the end user. Everybody has an information infrastructure already, some are just more effective than others. For those of you not happy with yours, IBM hasthe products, services and expertise to help with your data center transformation.
IBM wants to help its clients deliver the right information to theright people at the right time, to get the most benefits of information, while controlling costs and mitigatingrisks. There might be more than a dozen ways to address the challenges involved, but IBM's Information Infrastructure strategic initiative focuses on four key solution areas:
Last, but not least, I would like to welcome to the blogosphere IBM's newest blogger, Moshe Yanai, formerly the father of the EMC Symmetrix and now leading the IBM XIV team. Already from his first poston his new [ThinkStorage blog], I can tell he is not going to pullany punches either.
Continuing my quest to "set the record straight" about [IBM XIV Storage System] and IBM's other products, I find myself amused at some of the FUD out there. Some are almost as absurd as the following analogy:
Humans share over 50 percent of DNA with bananas. [source]
If you peel a banana, and put the slippery skin down on the sidewalk outside your office building, it couldpose a risk to your employees
If you peel a human, the human skin placed on the sidewalk in a similar manner might also pose similar risks.
Mr. Jones, who applied for the opening in your storage administration team, is a human being.
You wouldn't hire a banana to manage your storage, would you? This might be too risky!
The conclusion we are led to believe is that hiring Mr. Jones, a human being, is as risky as puttinga banana peel down on the sidewalk. Some bloggers argue that they are merely making a series of factual observations,and letting their readers form their own conclusions. For example, the IBM XIV storage system has ECC-protected mirrored cache writes. Some false claims about this were [properly retracted]using strike out font to show the correction made, other times the same statement appears in another post from the same blogger that[have not yet beenretracted] (Update: has now been corrected). Other bloggers borrow the false statement [for their own blog], perhaps not realizing theretractions were made elsewhere. Newspapers are unable to fix a previous edition, so are forced to publishretractions in future papers. With blogs, you can edit the original and post the changed version, annotated accordingly, so mistakes can be corrected quickly.
While it is possible to compare bananas and humans on a variety of metrics--weight, height, and dare I say it,caloric value--it misses the finer differences of what makes them different. Humans might share 98 percent withchimpanzees, but having an opposable thumb allows humans to do things that chimpanzeesother animals cannot.
Full Disclosure: I am neither vegetarian nor cannibal, and harbor no ill will toward bananas nor chimpanzees.No bananas or chimpanzees were harmed in the writing of this blog post. Any similarity between the fictitiousMr. Jones in the above analogy and actual persons, living or dead, is purely coincidental.
So let's take a look at some of IBM XIV Storage System's "opposable thumbs".
The IBM XIV system comes pre-formatted and ready to use. You don't have to spend weeks in meetings deciding betweendifferent RAID levels and then formatting different RAID ranks to match those decisions. Instead, you can start using the storage on the IBM XIV Storage System right away.
The IBM XIV offers consistent performance, balancing I/O evenly across all disk drive modules, even when performing SnapShot processing, or recovering from component failure. You don't have to try to separate data to prevent one workload from stealing bandwidth from another. You don't have to purchase extra software to determine where the "hot spots" are on the disk. You don't have to buy othersoftware to help re-locate and re-separate the data to re-balance the I/Os. Instead, you just enjoy consistentperformance.
The IBM XIV offers thin provisioning, allowing LUNs to grow as needed to accommodate business needs. You don'thave to estimate or over-allocate space for planned future projects. You don't have to monitor if a LUN is reaching80 or 90 percent full. You don't have to carve larger and larger LUNs and schedule time on the weekends to move thedata over to these new bigger spaces. Instead, you just write to the disk, monitoring the box as a whole, ratherthan individual LUNs.
The IBM XIV Storage System's innovative RAID-X design allows drives to be replaced with drives of any larger or smaller capacity. You don't have to find the exact same 73GB 10K RPM drive to match the existing 73GB 10K RPM drive that failed. Some RAID systems allow "larger than original" substitutions, for example a 146GB drive to replace a 73GB drive, but the added capacity is wasted, because of the way most RAID levels work. The problemis that many failures happen 3-5 years out, and disk manufacturers move on to bigger capacities and differentform factors, making it sometimes difficult to find an exact replacement or forcing customers to keep their own stockof spare drives. Instead, with the IBM XIV architecture, you sleep well at night, knowing it allows future drive capacities to act as replacements, and getting the full value and usage of that capacity.
In the case of IBM XIV Storage System, it is not clear whether
"Vendors" are those from IBM and IBM Business Partners, including bloggers like me employed by IBM,and "everybody else" includes IBM's immediate competitors, including bloggers employed by them.
-- or --
"Vendors" includes IBM and its competitors including any bloggers, so that "everybody else" refers instead to anyone not selling storage systems, but opinionated enough to not qualify as "objective third-party sources".
-- or --
"Vendors" includes official statements from IBM and its competitors, and "everybody else" refers to bloggerspresenting their own personal or professional opinions, that may or may not correspond to their employers.
That said, feel free to comment below on which of these you think the last two points of Steinhardt's rule istrying to capture. Certainly, I can't argue with the top two: a customer's own experience and the experiencesof other customers, which I mentioned previously in my post[Deceptively Delicious].
In that light, here is a 5-minute video on IBM TV with a customer testimonial from the good folksat [NaviSite], one of our manycustomer references for the IBM XIV Storage System.
"IBM announced that Northwest Radiology Network has gone live with a new virtualized enterprise of IBM servers and storage to support its growing medical imaging needs, giving its four locations an enterprise-class infrastructure which enables its doctors to recover medical image reports faster for analysis and enables remote 24x7 access to its medical image report system.
Founded in 1967, Northwest Radiology (NWR) is ranked as one of the largest physician groups in the Indianapolis, Indiana area. With 180 employees who offer the Central Indiana community comprehensive inpatient and outpatient imaging services such as mammography, ultrasonography, CT scans, PET-CT scans, bone density scans and MRIs – the Network had a dramatic need to develop a centralized infrastructure where large amounts of data could be stored and shared. A new data center would benefit the company’s clientele; which includes area hospitals and doctor’s offices serving thousands of patients each year.
Storing more than ten thousand medical imaging reports and radiographic images each month for doctors to analyze, the Network realized it had single points of failure and at one point a critical report server failed. Northwest Radiology turned to IBM and IBM Business Partner Software Information Systems (SIS) for a more efficient solution to prevent any possible downtime in the future.
SIS recommended and installed a virtualized infrastructure with IBM servers and storage as the heart of Northwest Radiology’s Indianapolis data center. By April 2007, Northwest Radiology replaced eight servers and direct attached storage with just two IBM System x3650 servers connected to an IBM System Storage DS3400. Today, the new servers run 15 virtual servers to ensure the availability of their services 24x7. When the business needs it, a new server can be provisioned in just minutes. With a Fibre Channel on the SAN Disk, the DS3400 not only increased performance but also met NWR’s requirement to not have one single point of failure. With three TB of storage capacity, they can meet the demands of increased business well into the future. The systems are also now easily managed from a remote site."
“Uptime is paramount in our business. We selected IBM based on the reliability and flexibility of IBM System x servers and the IBM System Storage DS3400,” said Marty Buening, IT Director, Northwest Radiology Network. “The virtualized infrastructure and the SAN storage array that SIS and IBM brought to the table is improving our service and giving our doctors and staff piece of mind knowing each patient’s medical imaging reports are always available.”
Second, we have [Iowa Health System], a large enterprise with over 19,000 employees, managing four million patients and hundreds of TBs of data.
Here is a 4-minute video on IBM TV from the good folks at Iowa Health System discussing theIBM Grid Medical Archive Solution (GMAS) as part of their information infrastructure for theirPicture Archiving and Communication Systems (PACS) application.
In both cases, IBM technology was able to provide remote access to medical information, making images and patient records available to more doctors, specialists and radiologists. Last January, in my post[Five in Five], IBM had predicted that remote access to healthcare would have an impact over the next five years.
Whether you are a small company or a large one, IBM probably has the right solution for you.
Well, this has been an interesting two weeks. On week 1, I focused on IBM's strategy and four keysolutions areas: Information Availability, Information Security, Information Retention, and InformationCompliance. On week 2, I focused on individual products, their attributes, features and functions.Which week drew more blog traffic? You guessed it--week 1. Apparently, people want to know more aboutsolutions to their challenges and problems, and not just see what piece part components are available.
While IBM had switched over to solution-selling a while ago, some of our competitors are still inproduct-selling mode, and try to frame all competitive comparisons on a product-by-product basis.In my post[Supermarkets and Specialty Shops], I drew the analogy that the IT supermarkets (IBM, HP, Sun and Dell) are focusedon selling solutions, but the IT specialty shops (HDS, EMC, and others) are still focused on products.
Certainly, the transition from product-focused to solution-focused is not an easy one. As the IT industry matures, more and more clients are looking to buy solutions from theirvendors. What does it take to change behaviour of newly acquired employees, recently hired sales reps, and business partners, many of whom come from product-centric cultures, to match this dramatic shift in the marketplace? Let's take a look at change in other areas of the world.
On the[Freakonomics blog], Stephen Dubner discusses how clever people in Israel have figured out a way to get people to clean up after their pets in public places. This is a problem in many countries. Here we see an old idea, the [carrot-and-stick] approach, combined with newinformation technology. Here's an excerpt:
"In order to keep a city’s streets clean of dog poop, require dog owners to submit DNA samples from their pets when they get licenses; then use that DNA database to trace any left-behind poop and send the dogs’ owners stiff fines.
Well, it took three years but the Israeli city of Petah Tikva has actually put this plan to work:
The city will use the DNA database it is building to match feces to a registered dog and identify its owner.
Owners who scoop up their dogs’ droppings and place them in specially marked bins on Petah Tikva’s streets will be eligible for rewards of pet food coupons and dog toys.
But droppings found underfoot in the street and matched through the DNA database to a registered pet could earn its owner a municipal fine."
Sometimes, if enough people change, then changing behaviours of the few remaining becomes much easier. DanLockton on his Architectures of Control blog posts about the[London Design Festival - Greengaged]. This year, the festival focused on behavior changes for a greener environment, ecodesign and sustainable issues in design.Here's an excerpt and corresponding 5-minute YouTube video:
Lea argued three important points relevant to behaviour change:
Behaviour change requires behaviour (i.e. the behaviour of others: social effects are critical, as we respond to others’ behaviour which in turn affects our own; targeting the ‘right’ people allows behaviour to spread)
Behaviour and motivation are two different things: To change behaviour, you need to understand and work with people’s motivations - which may be very different for different people.
Desire is not enough: lots of people desire to behave differently, but it needs to be very easy for them to do it before it actually happens."
Of course, tax and government regulations can heavily influence behaviour and decisions. Since today is[International Talk Like a Pirate Day], I thought I would finish this post off with this interesting piece on Google barges. Some companies, like IBM and Google, seem more adaptable to changing behaviour and trying out fresh new ideas.Will Runyon over on the Raised Floor blog, has a post about Google's patent for[Data center barges on the sea]:"The idea is to use waves to power the data centers, ocean water to cool them, and a moored distance of seven miles or more to avoid paying taxes."
Arrr! Now that's what I call a new way of looking at things!
Continuing this week's theme on products that were part of last week'sIBM Information Infrastructure launch, today I'll cover the TS2900.
IBM System Storage TS2900 Tape Autoloader
This little baby is SWEET! At 1U high, it holds a single drive and up to 9 cartridges,up to a total of 14.4 TB at 2:1 compression. Thedrive can be a Half-Height (HH) LTO-3 or LTO-4 drive. (It is called an autoloader because there isonly a single drive. Automation with multiple drives are called libraries).
This can be rack-mounted, or sit on your desktop. There is an I/O station for insertingor removing individual cartridges, as well as a removable tape magazine to populate orremove the tapes in a more efficient manner.
Both LTO3 and LTO4 support a mix of regular and "Write Once, Read Many" (WORM) media tohelp comply with regulations demanding "Non-erasable, Non-rewriteable" storage. TheLTO4 can also support on-drive encryption, managed by the IBM Encryption Key Manager (EKM).
To learn more, see the IBM System Storage[TS2900 page].
In Monday's post, [IBM Information Infrastructure launches today], I explained how this strategic initiative fit into IBM's New EnterpriseData Center vision. The launch was presented at the IBM Storage and Storage Networking Symposium to over 400 attendeesin Montpelier, France, with corresponding standing-room-only crowds in New York and Tokyo.
This post will focus on Information Retention, the third of the four-part series this week.
Here's another short 2-minute video, on Information Retention
Let's start with some interesting statistics.Fellow blogger Robin Harris on his StorageMojo blog has an interesting post:[Our changing file workloads],which discusses the findings of study titled"Measurement and Analysis of Large-Scale Network File System Workloads"[14-page PDF]. This paper was a collaborationbetween researchers from University of California Santa Cruz and our friends at NetApp.Here's an excerpt from the study:
Compared to Previous Studies:
Both of our workloads are more write-oriented. Read to write byte ratios have significantly decreased.
Read-write access patterns have increased 30-fold relative to read-only and write-only access patterns.
Most bytes are transferred in longer sequential runs. These runs are an order of magnitude larger.
Most bytes transferred are from larger files. File sizes are up to an order of magnitude larger.
Files live an order of magnitude longer. Fewer than 50 percent are deleted within a day of creation.
Files are rarely re-opened. Over 66 percent are re-opened once and 95% fewer than five times.
Files re-opens are temporally related. Over 60 percent of re-opens occur within a minute of the first.
A small fraction of clients account for a large fraction of file activity. Fewer than 1 percent of clients account for50 percent of file requests.
Files are infrequently shared by more than one client. Over 76 percent of files are never opened by more than one client.
File sharing is rarely concurrent and sharing is usually read-only. Only 5 percent of files opened by multiple clients are concurrent and 90 percent of sharing is read-only.
Most file types do not have a common access pattern.
Why are files being kept ten times longer than before? Because the information still has value:
Provide historical context
Gain insight to specific situations, market segment demographics, or trends in the greater marketplace
Help innovate new ideas for products and services
Make better, smarter decisions
National Public Radio (NPR) had an interesting piece the other day. By analyzing old photos, a researcher for Cold War Analysis was able to identify an interesting [pattern for Russian presidents]. (Be sure to listen to the 3-minute audio to hear a hilarious song about the results!)
Which brings me to my own collection of "old photos". I bought my first digital camera in the year 2000,and have taken over 15,000 pictures since then. Before that,I used 35mm film camera, getting the negatives developed and prints made. Some of these date back to my years in High School and College. I have a mix of sizes, from 3x5, 4x6 and 5x7 inches,and sometimes I got double prints.Only a small portion are organized intoscrapbooks. The rest are in envelopes, prints and negatives, in boxes taking up half of my linen closet in my house.Following the success of the [Library of Congress using flickr],I decided the best way to organize these was to have them digitized first. There are several ways to do this.
This method is just too time consuming. Lift the lid place 1 or a few prints face down on the glass, close the lid,press the button, and then repeat. I estimate 70 percent of my photos are in [landscape orientation], and 30 percent in [portrait mode]. I can either spend extra time toorient each photo correctly on the glass, or rotate the digital image later.
I was pleased to learn that my Fujitsu ScanSnap S510 sheet-feed scanner can take in a short stack (dozen or so) photos, and generate JPEG format files for each. I can select 150, 300 or 600dpi, and five levels of JPEG compression.All the photos feed in portrait mode, which I can then rotate later on the computer once digitized.A command line tool called [ImageMagick] can help automate the rotations.While I highly recommend the ScanSnap scanner, this is still a time-consuming process for thousands of photos.
"The best way to save your valuable photos may be by eliminating the paper altogether. Consider making digital images of all your photos."
Here's how it works:You ship your prints (or slides, or negatives) totheir facility in Irvine, California. They have a huge machine that scans them all at 300dpi, no compression, andthey send back your photos and a DVD containing digitized versions in JPEG format, all for only 50 US dollars plusshipping and handling, per thousand photos. I don't think I could even hire someone locally to run my scanner for that!
The deal got better when I contacted them. For people like me with accounts on Facebook, flickr, MySpace or Blogger,they will [scan your first 1000 photos for free] (plus shipping and handling). I selected a thousand 4x6" photos from my vast collection, organized them into eight stacks with rubber bands,and sent them off in a shoe box. The photos get scanned in landscape mode, so I had spent about four hours in preparing what I sent them, making sure they were all face up, with the top of the picture oriented either to the top or left edge.For the envelopes that had double prints, I "deduplicated" them so that only one set got scanned.
The box weighed seven pounds, and cost about 10 US dollars to send from Tucson to Irvinevia UPS on Tuesday. They came back the following Monday, all my photos plus the DVD, for 20 US dollars shipping and handling. Each digital image is about 1.5MB in size, roughly 1800x1200 pixels in size, so easily fit on a single DVD. The quality is the sameas if I scanned them at 300dpi on my own scanner, and comparable to a 2-megapixel camera on most cell phones.Certainly not the high-res photos I take with my Canon PowerShot, but suitable enough for email or Web sites. So, for about 30 US dollars, I got my first batch of 1000 photos scanned.
ScanMyPhotos.com offers a variety of extra priced options, like rotating each file to the correct landscape or portrait orientation, color correction, exact sequence order, hosting them on their Web site online for 30 days to share with friends and family, and extra copies of the DVD.All of these represent a trade-off between having them do it for me for an additional fee, or me spending time doing it myself--either before in the preparation, or afterwards managing the digital files--so I can appreciate that.
Perhaps the weirdest option was to have your original box returned for an extra $9.95? If you don't have a hugecollection of empty shoe boxes in your garage, you can buy a similarly sized cardboard box for only $3.49 at the local office supply store, so I don't understand this one. The box they return all your photos in can easily be used for the next batch.
I opted not to get any of these extras. The one option I think they should add would be to have them just discardthe prints, and send back only the DVD itself. Or better yet, discard the prints, and email me an ISO file of the DVD that I can burn myself on my own computer.Why pay extra shipping to send back to me the entire box of prints, just so that I can dump the prints in the trash myself? I will keep the negatives, in case I ever need to re-print with high resolution.
Overall, I am thoroughlydelighted with the service, and will now pursue sending the rest of my photos in for processing, and reclaim my linen closet for more important things. Now that I know that a thousand 4x6 prints weighs 7 pounds, I can now estimate how many photos I have left to do, and decide on which discount bulk option to choose from.
With my photos digitized, I will be able to do all the things that IBM talks about with Information Retention:
Place them on an appropriate storage tier. I can keep them on disk, tape or optical media.
Easily move them from one storage tier to another. Copying digital files in bulk is straightforward, and as new techhologies develop, I can refresh the bits onto new media, to avoid the "obsolescence of CDs and DVDs" as discussed in this article in[PC World].
Share them with friends and family, either through email, on my Tivo (yes, my Tivo is networked to my Mac and PC and has the option to do this!), or upload themto a photo-oriented service like [Kodak Gallery or flickr].
Keep multiple copies in separate locations. I could easily burn another copy of the DVD myself and store in my safe deposit box or my desk at work.With all of the regional disasters like hurricanes, an alternative might be to backup all your files, including your digitized photos, with an online backup service like [IBM Information Protection Services] from last year's acquisition of Arsenal Digital.
If the prospect of preserving my high school and college memories for the next few decades seems extreme,consider the [Long Now Foundation] is focused on retaining information for centuries.They areeven suggesting that we start representing years with five digits, e.g., 02008, to handle the deca-millennium bug which will come into effect 8,000 years from now. IBM researchers are also working on [long-term preservation technologies and open standards] to help in this area.
For those who only read the first and last paragraphs of each post, here is my recap:Information Retention is about managing [information throughout its lifecycle], using policy-based automation to help with the placement, movement and expiration. An "active archive" of information serves to helpgain insight, innovate, and make better decisions. Disk, tape, and blended disk-and-tape solutions can all play a part in a tiered information infrastructure for long-term retention of information.
