[Earth Day] is celebrated in many countries on April 22, which marks the anniversary of the birth of the modern environmental movement in 1970. Others celebrate this on the March equinox.
IBM has finally aggregated everything that we are doing around "Green" initiatives onto a single[IBM Green] landing page. This has everything from IBM's own activities as well as what we sell to our clients.
Also, to mark this occasion, IBM held an internal contest for employees to make videos about Earth Day,the environment, and IT's role in making the situation better. The grand prize winner, and 10 secondprize winners, are available on this [IBM Green Contest - YouTube channel].Of these, I liked "New Life for Old Silicon" (shown here on the left).
IBM also developed [Power Up, the Game], which is theEarth Day Network's "official" game for today's festivities. It's a 3-D game created by IBM Research to help save a fictitious planet - the goal being to help students learn about ecology and climate change. This game is also hoped to motivate young students to get interested in math, scienceand technology.Eightbar has a great post [PowerUp - A serious game out inthe wild] discussing this.Here's also a 3-minute[the making of "Power Up, the game" video] to geta behind-the-scenes look.The game is a downloadable Windows client that then connects to the main servers to run.
In addition to creating the Dilbert cartoon, Scott Adams has a blog, which sometimes is quite serious,and other times quite funny. The anticipated 30x cost of "Flash Drives" for Enterprise disk systems reminded meof one of Scott's articles from November 2007 titled [Urge to Simplify].Here's an excerpt:
Now the casinos have people trained, like chickens hoping for pellets, to take money from one machine (the ATM), carry it across a room and deposit in another machine (the slot machine). I believe B.F. Skinner would agree with me that there is room for even more efficiency: The ATM and the slot machine need to be the same machine.
The casinos lose a lot of money waiting for the portly gamblers with respiratory issues to waddle from the ATM to the slot machines. A better solution would be for the losers, euphemistically called “players,” to stand at the ATM and watch their funds be transferred to the hotel, while hoping to somehow “win.” The ATM could be redesigned to blink and make exciting sounds, so it seems less like robbery.
I’m sure this is in the five-year plan. Longer term, people will be trained to set up automatic transfers from their banks to the casinos. People will just fly to Vegas, wander around on the tarmac while the casino drains their bank accounts, then board the plane and fly home. The airlines are already in on this concept, and stopped feeding you sandwiches a while ago.
Perhaps EMC can redesign its DMX-4 to "blink and make exciting sounds" as well. The Flash Drives were designedfor the financial services industry, so those disk systems could be directly connected to make transfers between the appropriate bank accounts.
Well, tomorrow is the Winter solstice, at least for those of us in the Northern hemisphere of the planet.As often happens, I have more vacation days left than I can physically take before they evaporateat the end of the year, so next week I will be off, going to see movies like the new["Golden Compass"]or perhaps read the latest book from [Richard Dawkins].
Next week, I suspect some of the kids on my block will be playing with radio-controlled cars orplanes. If you are not familiar with these, here's a [video on BoingBoing]that shows Carl Rankin's flying machines that he made out of household materials.
Which brings me to the thought of scalability. For the most part, the physics involvedwith cars, planes, trains or sailboats apply at the toy-size level as well as the real-world level. One human operator can drive/manage/sail one vehicle. While I have seen a chess master play seven opponents on seven chess boards concurrently, itwould be difficult for a single person to fly seven radio-controlled airplanes at the same time.
How can this concept be extended to IT administrators in the data center? They have to deal withhundreds of applications running on thousands of distributed servers.In a whitepaper titled [Single System Image (SSI)], the threeauthors write:
A single system image (SSI) is the property of a systemthat hides the heterogeneous and distributed nature of theavailable resources and presents them to users and applicationsas a single unified computing resource.
IBM has some offerings that can help towards this goal.
Even in the case where yourvehicle is being pulled by eight horses--(or eight reindeer?)--a single operator can manage it, holding the reins in both hands. In the same manner,IBM has spent a lot of investment and research into supercomputers, where hundreds of individualservers all work together towards a common task. The operator submits a math problem, for example,and the "system system image" takes care of the rest, dividing the work up into smaller chunksthat are executed on each machine.
When done with IBM mainframes, it is called a Parallel Sysplex. The world's largest business workloadsare processed by mainframes, and connecting several together and working in concert makes this possible.In this case, the tasks are typically just single transactions, no need to divide them up further, justbalance the workload across the various machines, with shared access to a common database and storageinfrastructure so they can all do the work equally.
Last August, in my post [Fundamental Changes for Green Data Centers], I mentioned that IBM consolidated 3900 Intel-based servers onto 33 mainframes. This not only saves lots of electricity, but makes it much easier for the IT administratorsto manage the environment.
Parallel Sysplex configurations often require thousands of disk volumes, which would have been quitea headache dealing with them individually. With DFSMS, IBM was able to create "storage groups" wherea few groups held the data. You might have reasons to separate some data from others, put them inseparate groups. An IT administrator could handle a handful of storage groups much easier than thousandsof disk volumes. As businesses grow, there would be more data in each storage group, but the numberof storage groups remains flat, so an IT administrator could manage the growth easily.
IBM System Storage SAN Volume Controller (SVC) is able to accomplish this for other distributed systems.All of the physical disk space assigned to an SVC cluster is placed into a handful of "managed diskgroups". As the system grows in capacity, more space is added to each managed disk group, but few IT administrators can continue to manage this easily.
The new IBM System Storage Virtual File Manager (VFM) is able to aggregate file systems into one globalname space, again simplifying heterogeneous resources into a single system image. End users have a singledrive letter or mount point to deal with, rather than many to connect to all the disparate systems.
Lastly we get to the actual management aspect of it all. Wouldn't it be nice if your entire data centercould be managed by a hand-held device with two joysticks and a couple of buttons? We're not quite there yet, but last October we announced the [IBM System Storage Productivity Center (SSPC)]. This is a master consolethat has a variety of software pre-installed to manage your IBM and non-IBM storage hardware, includingSAN fabric gear, disk arrays and even tape libraries. It lets the storage admin see the entire data centeras a single system image, displaying the topology in graphical view that can be drilled down using semanticzooming to look at or manage a particular device or component.
Customers are growing their storage capacity on average 60 percent per year. They could do this by havingmore and more things to deal with, and gripe about the complexity, or they can try to grow theirsingle system image bigger, with interfaces and technologies that allow the existing IT staff to manage.
The movie industry is slowly making the conversion to digital.
For about 25 years, movies were silent, actors acted, text was shown on the screen, and an organ or piano player added the musical score. My mother was a concert pianist, so I grew up listening to all kinds of piano music. Last weekend, while I was in Chicago for St. Patricks Day, we watched and listened to the dueling pianos at a bar called "Howl at the Moon". Those not familiar with this art form can watch this 1-minute video of Star Wars re-imagined as a Silent Movie.
About 80 years ago, "talkies" appeared. The sound was converted to a series of colors that were recorded as a separate strip on the film media itself, hence the name "soundtrack". When the movie ran, the colors would then be converted back to voice and music. While the live piano players were out of jobs, the move to sound created a whole new industry for foley artists, orchestras and composers.InformationWeek's Mitch Wagner explains in Something Will Be Lost thatgreat artists like Charlie Chaplin and Mary Pickford never completely made the transition to talkies.
Now the movie industry is changing again, this time from film to digital format. Thanks to digital, we can now see videos on the internet, such as this set of Impressive Palindromes parody of a Bob Dylan song.
While movies are digital when you rent them from the DVD store, download them on iTunes, or play them on YouTube, they are still mostly in analog format on 35mm or 70mm film stock when you see them on the big screen.
My first "digital projection" experience was the movie "Ice Age" shown in Denver, Colorado. The theatre owner came out to show us what film stock looks like, and then how small the DVD was that held the digital version. The theatre also showed previews of other movies first on film, then in digital, so that we could see the difference in quality.My second experience was "Star Wars: Attack of the Clones (episode II)", which I saw opening night at the Ziegfeld theatre in New York City. This was a huge theatre, and we had front row seats in the upper balcony.
Of course, the transition of film stock to digital projection is just one of the many trends resulting in the fast growth of computer IT storage. Documents transitioned from paper, to being scanned into digital format, to being created digitally using word processing software. Likewise, photographs went from film, to being scanned, to being captured with digital cameras.
As with talkies, history repeats itself; the transition to digital projection is not going smoothly.NPR's Laura Sydell reports thatDigital Projection in Theaters Slowed by Dispute. The dispute is between movie production companies and theatre owners. Currently, it is quite expensive to send out film stock to all the theatres, so the transition to digital will save the movie production companies lots of money. On the other hand, installing digital projection equipment will be costly for theatre owners. How the two groups will share the burdensome costs to convert this infrastructure is still under negotiation.
As a fan of going to the movies, I hope they resolve this dispute soon.
Before acquisition, Diligent offered only software. The task of putting this software on an appropriate x86 server with sufficientmemory and processor capability was left as an exercise for the storage admin. With the TS7650G, IBM installs theProtectTIER software on the fastest servers in the industry, the IBM System x3850 M2 and x3950 M2. This eliminateshaving the storage admins pretend that they have hardware engineering degrees.
Before acquisition, the software worked only on a single system. IBM was able to offer multiple configurations of the TS7650G, including a single-controller model as well as a clustered dual-controller model. The clustered dual-controller model can ingest data at an impressive 900 MB/sec, which is up to nine times faster than some of thecompetitive deduplication offerings.
Before acquisition, ProtecTIER emulated DLT tape technology. This limited its viability, as the market sharefor DLT has dropped dramatically, and continues to dwindle. Most of the major backup software support DLT as anoption, but going forward this may not be true much longer for new tape applications.IBM was able to extend support by adding LTO emulation on theTS7650G gateway, future-proofing this into the 21st Century.
At last week's launch, covering so many products with so few slides, this announcement was shrunken down to a single line "Store 25 TB of backups onto 1 TB of disk, in 8 hours" and perhaps a few people missed that this wasactually covering two key features.
With deduplication, the TS7650G might get up to 25 times reduction on disk. If you back up a 1 TB data basethat changes only slightly from one day to the next, once a day for 25 days, it might only take 1 TB, or so, of disk tohold all the unique versions, as most of the blocks would be identical, rather than 25 TB on traditional disk or tapestorage systems. The TS7650G can manage up to 1 PB of disk,which could represent in theory up to 25 PB of backup data.
With an ingest rate of 900 MB/sec, the TS7650G could ingest 25 TB of backups during a typical 8 hour backup window.
The 25 TB of the first may not necessarily be the 25 TB of the second, but the wording was convenient for marketingpurposes, and a comma was used to ensure no misunderstandings.Of course, depending on the type of application, the frequency of daily change, and the backup software employed, your mileage may vary.
This week I am off to Budapest, Hungary, for business meetings. It is the closest major city to IBM'smanufacturing plant in a small town called Vac (rhymes with "knots") where the IBM System Storage DS8000 seriesand SAN Volume Controller are assembled.
I have arrived safely to Istanbul, Turkey for the [Systems Technical University 2014] conference. The conference will feature experts from IBM Power Systems, IBM System x, IBM PureSystems, and IBM System Storage.
Here is the view from my hotel window. Up until the 19th century, this was open countryside. Around 1890, the Bomonti brothers from Switzerland set up a brewery, which was moved to this section of town in 1902, becoming the first Turkish brewery. In 1934, the brewery was nationalized and became the Istanbul Tekel Beer Factory. The Hilton Bomonti hotel where the conference is being held is named after these brothers.
Since this is my first time to Istanbul, and I did not have meetings until later in the afternoon for the conference, I decided to a bit of sightseeing.
(A special thanks to Gail Godbey of [Encounter Tours/Kaletours] who organized this entire tour of sightseeing for me on such short notice!)
The hippodrome was a stadium for horse and chariot racing, but now is just a square with a few obelisks. This one is the Thutmosis Obelisk from Egypt. The word hippodrome comes from the Greek hippos, meaning horse, and dromos, meaning path or way. Hippodromes were common features of Greek cities in the Hellenistic, Roman and Byzantine eras. My tour guide Erol Azor did a great job explaining everything.
My favorite stop of the day was the Blue Mosque, named after the blue tiles used on the dome. It is 43 meters high, making it one of the tallest mosques in the city. There are over 3,000 mosques here in Istanbul. In Turkish, this place is called Sultan Ahmet Camii after the Sultan Ahmet that had it built from 1609-1616. There are six minarets. The legend goes that the Sultan asked for a "gold" minaret, but the word for "gold" in Arabic sounds a lot the number six in Turkish, so that is why there are six of them.
Right next to the Blue Mosque is the Hagia Sofia, which was a Christian church first, then converted to a mosque, and now is a musuem. It was closed on Mondays, so all I could do was take pictures from the outside. Tulips are in full bloom throughout the city this month of April. If you notice, the minaret on the right is different color. Often, new sultans would add a minaret to an existing mosque, using whatever materials were available at the time. Kind of like adding a bedroom to an existing house.
Underneath the ground is the Basilica Cistern which held the drinking water for the city. The water came in on viaduct, and was kept underground. Today, it has a foot of water, and some fish, for people to admire the architecture employed.
Of course, no visit to Istanbul is complete without stopping at the Grand Bazaar. With over 4,000 tiny shops, it is a madhouse of gold and silver jewelry, blue jeans, leather goods, scarves, persian rugs, and antiques. Some places offered me free samples of Turkish delight, which are delicious cubes of flavored gelatin.
My day ended at the Topkapi palace. The word Topkapi is Turkish for "Cannon Gate", as this castle sits overlooking the peninsula and bosphorus strait that separates the Europe side from the Asian side of the city. Like the palace of Versaille in France, or Buckingham palace in England, the Topkapi palace was home to 36 sultans from 1299 to 1922.
You can spend hours here. There are beautiful gardens and various buildings surrounded by five kilometers of castle wall. Inside the buildings are displays of the family jewels, the clothes the sultans wore, their weapons, and religious relics.
It was good to get a flavor of the city, and a sense of the Turkish culture.
Over time, I have gotten many emails, comments and tweets related to this post. The instructions have been downloaded over 130,000 times!
The letter below was so inspiring that I felt I need to share it. (Published here with permission from the author, who goes by the screen name DaveAlex)
Thought you would like to know that I am working toward an AI Agent hopefully more advanced than "Watson Jr." although I will probably include the software behind it.
The hardware I have on hand is a System X3650M2 which I bought for $250 on eBay. It has four 2.66 GHz Xeons with 6 cores each, and 16 GB RAM. I have another 16 to install when I need it. I will shortly have 4 TB of HDD space on line, plus an addition 3 TB USB3 drive.
Ultimately, I hope to have some of the available knowledge bases on line, Freebase, CYC, etc which will handle specific information perhaps better than the Watson software by itself.
What the target (goal) that I am aiming for is a stationary version of Commander Data of Star Trek, Next generation.
I envision if having some form of self knowledge, being capable of processing graphical data, i.e., facial recognition, gesture interpretation, voice input/output, mathematical processing, with graphical output (display & hardcopy) and several additional features.
As I have studied this project, I am amazed at how much of the required software is already available. The biggest stumbling block is integrating the separate parts.
Back to Hardware. I just bought 2 Dell 2850 servers, each with dual Intel Xeons which can handle some of the tasks. If I need more processing power, I just happen to have about 10 other towers with Pentium IV or dual core processors sitting around, which can be pressed into service as needed. So far, my total cost is less than $1000 US Dollars, and my wife has not thrown me out yet. I continue to watch eBay for additional older used equipment for fractions of the original cost. My friends who follow my project keep telling me that I need to get on with the software, and add hardware as needed; they are absolutely correct, but I can't resist a bargain.
The power consumption is a potential problem, but I have a 4500 Watt solar array to use. The cooling could be a problem too, but my house sits into the side of hill, and can readily duct the air supply pass the sub-surface wall, perhaps with old Processor cooling fins glued to the wall.
I hope to get some hobby programmers involved in the project, it is a bit beyond my programming capabilities. I hope that I can live long enough to see it come to fruition; I am 78 now, and mentally in very good condition.
Wow! He is 78 years old! While others his age are playing shuffleboard at the nursing home, he is out there learning new things about the latest technology. I wish him the best of luck on this! If you would like to reach out to DaveAlex, send me a note or comment below, and I will forward them on to him.
I was in Raleigh this week, in business meetings, and had dinner last night at a Japanese Tepanyaki restaurant. The man next to me was dining alone, and said he worked for Cisco, a big company, "Had you heard of it?" he asked. Of course, I told him, I work for IBM, and IBM and Cisco have a strong working relationship, using each others products in both directions. He said he understood why they would use IBM, but why would IBM buy anything from them, and then he said, "Oh yes, your cafeteria".
At this point we realized he was talking about SYSCO, the food company, not Cisco, the storage networking technology partner. We both had a good laugh.
Which brings me to think of other "mis-heard" or "mis-interpreted" items that might have caught people off guard because they sounded similarly.
zFS versus ZFS
Some things are case-sensitive. Lower case zFS is the hierarchical file system for the z/OS mainframe environment, which was originally called "episode" file system that IBM acquired from TransArc. z/OS supports two file systems, HFS and zFS. Meanwhile, ZFS is one of the file systems available for Sun Solaris. Apple Mac OS is switching from its own HFS, different than the z/OS version, over the Sun's ZFS.
packs versus PACS
Older mainframers call disk volumes "packs". This started in the days where disks were "removable" and you can pack and unpack them into the drive unit.
PACS on the other hand refers to the "Picture Archive and Communication System" application environment used by hospitals and medical facilities to storage and share X-ray, Cardiology and Radiology images. Today, modern medical equipment are called "modalities" and directly connect to NAS storage via NFS or CIFS protocols. The images are immediately digitized and sent to disk, then tape, for long-term archive storage. IBM's Grid Medical Archive Solution (GMAS) is designed specifically for this environment.
rack versus RAC
Perhaps my favorite was when someone asked a high-level executive at a conference if their storage product supported Oracle RAC, and the response was that it supported anyone's rack, so long as it met the 19 inch standard. Everyone burst out laughing, and he probably had to be explained what was going on afterward.
Oracle RAC refers to Real Application Cluster, allowing multiple Oracle servers to work together as a system. A "rack" is just the powered shelf, typically 19" wide, and typically 25U or 42U tall, that allows modular servers, storage or network gear be placed together in a data center. A "U" is 1.75 inches, the thickness of a "two-by-four" piece of lumber. If you have ever used a 3.5 inch or 5.25 inch floppy diskette, then you already know the 2U and 3U sizes.
I am sure there are many other examples of similar sounding terms and phrases. If you have any to contribute, post a comment below!
I'm continuing my coverage of IBM Systems Journal's [fifteen articles about IBM Service Management].As storage hardware cost per GB declines 25 percent per year, the cost of labor has grown to nearly 70percent of the total IT budget. This brings new focus on how we do things, rather than what things siton the raised floor. Yesterday, my post summarized[the first five articles].Here is what I got out of the next five articles:
Integrated change and configuration management
IT Infrastructure Library (ITIL) best practice covers a variety of disciplines, including incident management,problem management, release management, service help desk, change management, and configuration management.IBM has combined the last two into a single database, and this paper provides insights gained fromimplementing these in practice. A special section talks about how service providers can support multipleclients that must be kept separate from each other.
The process of building a Process Manager: Architecture and design patterns
Business processes coordinate and sequence the work done by a collection of people.Most companies define their business process from scratch, and develop their own applicationsto support their implementation. Process Managers are "out of the box" applications that help customers integrateand automate more quickly than building from scratch. These Process Managers leverage and update informationabout configuration items (CIs) in the configuration management database (CMDB). One of the first developedby IBM was the IBM Tivoli Storage Process Manager.
Integration of domain-specific IT processes and tools in IBM Service Management
ITIL tells you what needs to get done, but it doesn't tell you exactly how to do it. Completing a simplechange request to the IT environment can have a drastic impact on service level agreements (SLAs), utilization of existing storage capacity, and business operations. Sometimes it is important to use multipleProcess Manager applications together. To accomplish this, it is important to launch and land in contextat the appropriate points for smooth transition.
Using a model-driven transformational approach and service-oriented architecture for service deliver management
Companies are considering outsourcing as a way to focus on core competencies. However, the trend is towardselective outsourcing, where the customer controls the IT solution architecture and retains their legacy tools.As a result, service providers inherit the business and IT processes from their clients. IBM Research has developed the model-driven business transformation (MDBT) method that choreographs workflow tools with humanactivities. A "balanced scorecard" allows both client and outsourcer monitor progress towards strategic goals.
Catalog-based service request management
Service providers (outsourcers) are able to bring the latest IT technology, best practices, and skilledservice delivery teams. Unfortunately, unique business processes from each client limits the ability to leveragethese resources effectively. A service delivery management platform (SDMP) catalog serves as a repositoryof atomic services and the delivery teams that can perform them. This allows outsourcers to leverage resourcesacross multiple clients, while still being able to tailor business compositions of these atomic services to an individual client's requirements.
Recently, IBM and the University of Texas Medical Branch (UTMB) [launched an effort] using IBM's World Community Grid "virtual supercomputer" to allow laboratory tests on drug candidates for drug-resistant influenza strains and new strains, such as H1N1 (aka "swineflu"), in less than a month.
Researchers at the University of Texas Medical Branch will use [World Community Grid] to identify the chemical compounds most likely to stop the spread of the influenza viruses and begin testing these under laboratory conditions. The computational work adds up to thousands of years of computer time which will be compressed into just months using World Community Grid. As many as 10 percent of the drug candidates identified by calculations on World Community Grid are likely to show antiviral activity in the laboratory and move to further testing.
According to the researchers, without access to World Community Grid's virtual super computing power, the search for drug candidates would take a prohibitive amount of time and laboratory testing.
This reminded me of an 18-minute video of Larry Brilliant at the 2006 Technology, Entertainment and Design [TED] conference. Back in 2006, Larry predicted a pandemic in the next three years, and here it is 2009 and we have the H1N1 virus.
His argument was to have "early detection" and "early response" to contain worldwide diseases like this.
A few months after Larry's "call to action" in 2006, IBM and over twenty major worldwide public health institutions, including the World Health Organization [WHO] and the Centers for Disease Control and Prevention [CDC], [announced the Global Pandemic Initiative], a collaborative effort to help stem the spread of infectious diseases.
One might think that with our proximity to Mexico that the first cases would have been the border states, such as Arizona, but instead there were cases as far away as New York and Florida. The NYT explains in an article [Predicting Flu With the Aid of (George) Washington] that two rival universities, Northwestern University and Indiana University, both predicted that there would be about 2500 cases in the United States, based on air traffic control flight patterns, and the tracking data from a Web site called ["Where's George"] which tracks the movement of US dollar bills stamped with the Web site URL.
The estimates were fairly close. According to the Centers for Disease Control and Prevention [H1N1 Flu virus tracking page], there are currently 3009 cases of H1N1 in 45 states, as of this writing.
This is just another example on how an information infrastructure, used properly to provide insight, make predictions, and analyze potential cures, can help the world be a smarter planet. Fortunately, IBM is leading the way.
This is an interesting development. To understand it better, we need to go back to the 1930s. Malcolm McLean invented the shipping container in the 1930s in New Jersey, and later founded Sea-Land corporation. Rather than unpacking products from a ship, load onto a truck, then move those products onto a train, his innovation was to create a container that could be packed full of products, carried from ship, to truck, to train, without loading and unloading individual products as transportation means change. He named the size of his container "TEU".
TEU = 20 ft x 8.5 ft x 8.5 ft (twenty-foot equivalent unit)
In 1966, the standard shape and size was adopted by International Organization for Standardization (ISO).Today, over 90% of freight containers are 1 or 2 TEU
Sun's announcement is that they have packed up to 240 UNIX servers into a single TEU container. This can be dropped off at your facility, hook up your power and cooling, and start running. An alternative version is a disk-farm-in-a-can, having the TEU container filled with up to 2 PB of disk storage capacity.
Rich Bourdeau has written a nice article on InfoStor titled [Software as a Service (SaaS) meets Storage]. Last year, IBM acquired Arsenal Digital, and he mentions both in this article.It is interesting how this has evolved over the years.
Rent warehouse space for tapes
I remember when various companies offered remote storage for tapes. These would be temperature and humidity-controlledrooms, with access lists on who could bring tapes in, who could take tapes out, and so on. In the event of thedisaster, someone would collect the appropriate tapes and take them to a recovery site location.
Rent online/nearline storage from a Storage Service Provider (SSP)
SSPs rented storage space on disk, or provided automated tape libraries that could be written to. With tapes being ejected and stored in temperature/humidity-controlled vaults. Electronic vaulting eliminates a lot of theissues with cartridge handling and transportation, is more secure, and faster. Rented disk space, based on a Gigabytes-per-month rate, could be used for whatever the customer wanted. If these were for backups or archive,then the customer has to have their own software, to do their own processing at their own location, sending the data to the remote storage as appropriate, and manage their own administration.
Backup-as-a-Service and Archive-as-a-Service
We are now seeing the SaaS model applied to mundane and routine storage management tasks. New providers can offerthe software to send backups, the disk to write them to, and as needed the tape libraries and cartridges to rollover when the disk space is full. Disk capacity can be sized so that the most recent backups are on immediately accessible for fast recovery.
The same concept can be applied to archives. The key difference between a backup and an archive is that backups areversion-based. You might keep three versions of a backup, the most recent, and two older copies, in case something is wrong with the most recent copy, you can go back to older copies. This could be from undetected corruption of the data itself, or problems with the disk or tape media. An archive, on the other hand, is time-based. You want this data to be kept for a specific period of time, based on an event or fixed period of years.
Since BaaS and AaaS providers know what the data is, have some idea of the policies and usage patterns will be, can then optimize a storage solution that best meets service level agreements.
The Magic Quadrant is copyrighted concept by Gartner, representing a two-by-two grid that ranks various offerings from different vendors. Ideally, vendors want their products in the upper right "Leaders" quadrant. Yahoo Finance reports:
According to Gartner, Inc., "Leaders have the highest combined measures of an ability to execute and a completeness of vision. They have the most comprehensive and scalable products. They have a proven track record of financial performance and an established market presence. In terms of vision, they are perceived as thought leaders, having well-articulated plans for ease of use, how to address scalability and product breadth. For vendors to have long-term success, they must plan to address the expanded market requirements for change management and root-cause and performance analysis. Leaders must not only deliver to the current market requirements, which continue to change, but they also need to anticipate and deliver on future requirements. A cornerstone for leaders is the ability to articulate how these requirements will be addressed as part of their vision for resource management. As a group, leaders can be considered a part of most new purchase proposals, and they have high success rates in winning new business."
IBM TotalStorage Productivity Center is a strategic part of IBM Service Management, and a foundational component of the IBM Systems Director family. IBM is making a concerted effort across servers, networks, software and storage to help manage the IT infrastructure in a coordinated way.
