Yesterday's announcement that IBM had acquired XIV to offer storage for Web 2.0 applicationsprompted a lot of discussion in both the media and the blogosphere. Several indicated thatit was about time that one of the major vendors stepped forward to provide this, and it madesense that IBM, the leader in storage hardware marketshare, would be the first. Others were perhaps confused on what is unique with Web 2.0 applications. What has changed?
I'll use this graphic to help explain how we have transitioned through three eras of storage.
The first era: Server-centric
In the 1950s, IBM introduced both tape and disk systems into a very server-centric environment.Dumb terminals and dumb storage devices were managed entirely by the brains inside the server.These machines were designed for Online Transaction Processing (OLTP), everywhere from bookingflights on airlines to handling financial transfers.
The second era: Network-centric
In the 1980s and 1990s, dumb terminals were replaced with smarter workstations and personalcomputers; and dumb storage were replaced with smarter storage controllers. Local Area Networks (LANs)and Storage Area Networks (SANs) allowed more cooperative processing between users, servers andstorage. However, servers maintained their role as gatekeepers. Users had to go through aspecific server or server cluster to access the storage they had access to. These servers continuedtheir role in OLTP, but also manage informational databases, file sharing and web serving.
The third era: Information-centric
Today, we are entering a third era. Servers are no longer the gatekeepers. Smart workstationsand personal computers are now supplemented with even more intelligent handheld devices, Blackberryand iPhones, for example. Storage is more intelligent too, with some being able to offer file sharingand web serving directly, without the need of an intervening server. The roles of servers have changed,from gatekeepers, to ones that focuses on crunching the numbers, and making information presentableand useful.
Here is where Web 2.0 applications, digital media and archives fits in. These are focused on unstructured data that don't require relational database management systems. So long as the useris authorized, subscribed and/or has made the appropriate payment, she can access the information. With the appropriate schemes in place, information can now be mashed-up in a variety of ways, combined with other information that can render insights and help drive new innovations.
Of course, we will still have databases and online transaction processing to book our flights andtransfer our funds, but this new era brings in new requirements for information storage, and newarchitectures that help optimize this new approach.
Stephen Colbert, of The Colbert Report, explains the name changes in recent mergers of the Telecommunications industry. A discussion on "changing names" and how that impacts storage seems like a good way to wrap up the week's theme on naming conventions.
Name changes are sometimes painful, but often times done for a purpose, such as to promote a family. In the US, when a man and woman marries, the woman often changes her family name to match her husband, and the kids all adopt the father's family name. I say "often" because there are times where the woman keeps her name, or adds to it in a hyphenated way. ABC News reported that a Man Fights to Take Wife's Name in Marriage. KipEsquire, a lawyer, writes about it in his blogA stitch in haste.
IT industry changes the names of products that people knew as something else. Other times, they re-use an existing name, when really it is or should be different from the original. Last year, I took on the job of helping transition from our brand "TotalStorage" to the "System Storage" product line under the new "IBM Systems" brand. I help decide what stays the same name or what changes, when it should change, and how to announce that change.
On the disk side, IBM renamed Fibre Array Storage Technology, or FAStT, which was pronounced exactly like "fast", to DS4000 series. This was a big improvement, as people couldn't seem to spell it properly, with variations like "FastT". Nor could people pronounce it properly, saying "fast-tee" instead. The advantage of "DS" is that it is both easy to spell, and easy to pronounce. The DS4000 series continues to be "fast", providing excellent performance for its midrange price category.
IBM's Enterprise Storage Server (ESS) line went from model E10, to F20, to 750 and 800. When IBM came out with its replacement, the IBM TotalStorage DS8000, some people asked why it wasn't named the ESS 900, for example. The DS8000 is quite different internally, new hardware design and implementation, but is highly compatible with the ESS line, and shares much of the same functionality from microcode. Last year, it was replaced by the IBM System Storage DS8000 Turbo. Again, newer hardware, so it was easy to justify the new name change from "TotalStorage" to "System Storage".
Renaming a product risks losing its certifications and awards. For example, IBM spent a lot of time and money getting the OS/390 operating system certified as a "UNIX" platform. When it was renamed to z/OS, IBM had to do it all over again. Learning from this experience, IBM decided not to rename the SAN Volume Controllerto a new designation like "DS5750", as it enjoys the "number one" spot on both the SPC-1 and SPC-2 performance benchmarks, and is recognized as the leader in the disk storage virtualization marketplace. Renaming this product would mean losing that collateral.
IBM's "other disk systems" the N series posed another set of challenges. The current DS line already has entry-level (DS3000), midrange (DS4000) and enterprise-class (DS6000 and DS8000) products. The OEM agreement that IBM has with Network Appliance (NetApp) resulted in a new set of entry-level, midrange, and enterprise-class products. But these didn't fit nicely into the DS3000-to-DS8000 continuum. Instead, IBM decided to go with N series, using N3000 for entry-level, N5000 for midrange, and N7000 for enterprise-class. These are different than the numbers used by NetApp for their comparable, but not identical, offerings.
On the tape side, IBM decided to name the tape drives TS1000 and TS2000 range, tape libraries and automation with a TS3000 range, and tape virtualization to the TS7000 range. A lot of tape products already had 3000 numbering that had to change to fit this new scheme. This is why IBM's popular 3592 tape drive was renamed to the TS1120. The replacement to the 3494 Virtual Tape Server was named TS7700 Virtualization Engine.
Obviously, you can't change the names of products that are currently in the field, but what about existing software with minor updates? IBM decided to leave "TotalStorage Produtivity Center" under the "TotalStorage" brand until it has a significant version upgrade. Many people say "TPC" as a convenient acronym when referring to this product, but TPC is a registered trademark of the Professional Golfers Association (PGA) to refer to its "Tournament Players Club".
How can anyone confuse "managing storage" with "playing golf"? One activity is full of frustration that takes years or decades to master, involving the need to understand a variety of equipment and techniques to use each properly to accomplish your goals; and the other is an enjoyable activity, immediately productive in front of a single pane of glass managing all of your DAS, SAN and NAS storage, from reporting on your files and databases to managing storage networks and tape libraries.
Yesterday's post [Software Programmers as Bees]was not meant as "career advice", but certainly I got some interesting email as if it was.Orson Scott Card was poking fun at the culture clash between software programmers andmanagement/marketers, and I gave my perspective, having worked both types of jobs.
This is June. Many students are graduating from high school or college and lookingfor jobs. Some of these might be jobs just for the summer to make some spending money,and others mights be jobs like internships to explore different career paths. I found both programming and marketing are rewarding and interesting work, but each person is different.
There are a variety of ways to find out what your personality traits are,and then focus on those jobs or career paths that are best for those strengths. Hereis an online [Typology Test] based onthe work of psychologists Carl Jung and Isabel Myers-Briggs. The result is a four-letterscore that represents 16 possible personalities. For example, mine is "ENTP",which stands for "Extroverted, Intuitive, Thinking, Perceiving". You can find out otherfamous people that match your personality type. For ENTP, I am lumped together withfellow master inventor Thomas Edison, fellow author Lewis Carrol (Alice in Wonderland), Cooking great Julia Child, Comedians George Carlin and Rodney Dangerfield (I get no respect!),movie director Alfred Hitchcock, and actor Tom Hanks.
USA Today had an article ["CEOsvalue lessons from teen jobs"] which offers some career advice from successful business people.Of course, what worked for them may not work for you, all based on different personality types. Hereis an excerpt of the advice I thought the most useful:
"If you are committed, you will be successful." (unfortunately, the reverse is also true: if you are successful,you will be asked to move to a different job)
"Tackle offbeat jobs. Challenge conventional wisdom within reason. Come into contact with people from all walks of life."
"Show an interest, demonstrate you want to be on the job."
"Never limit yourself. Look beyond to what needs to be done, or should be done. Then do it. Stretch. Go beyond what others expect."
"Find a job that forces you to work effectively with people. No matter what you end up doing, dealing with others will be critical."
"Bring your best to the table every day. Learn professional responsibility and how to handle difficult situations."
"Listen carefully to what customers want."
Before IBM, I ran my own business. If you are thinking, "Maybe I will start my own business instead?" you might want to see this advice from Venture Capitalist [Guy Kawasaki on Innovation].While running your own business has advantages, like avoiding issues "working for the man", it has somedisadvantages as well. It is certainly not as easy as some people make it seem to be.
Of course, things are a lot different nowadays than they were when these CEOs were teenagers. And the pace ofchange does not seem to be slowing down any either. Here is a presentation on [SlideShare.net] that helps bring to focus the realities of globalization:
BladeCenterservers come in many flavors, including blades with Intel, AMD and POWER chipsets, and can be configured in Grid and SuperComputer configurations. Up to 14 blade servers can fit intoa single 7U-high chassis, making this twice as dense as standard 1U-high rack-mounted servers.
System x, the new "IBM Systems" name for our popular xSeries product line, support Intel and AMD chipsets. These come in both rack-mountedand tower configurations. These also are idea for clustered and SuperComputer configurations.[Read More]
It's Thursday here at the [Data Center Conference] here in Las Vegas. Trying to keep up with all the sessions and activities has been quite challenging. As is often the case, there are more sessions that I want to attend than I physically am able to, so have to pick and choose.
Making the Green Data Center a Reality
The sixth and final keynote was an expert panel session, with Mark Bramfitt from Pacific Gas and Electric [PG&E], and Mark Thiele from VMware.
Mark explained PG&E's incentive program to help data centers be more energyefficient. They have spent $7 million US dollars so far on this, and he has requested another$50 million US dollars over the next three years. One idea was to put "shells" aroundeach pod of 28 or so cabinets to funnel the hot air up to the ceiling, rather than havingthe hot air warm up the rest of the cold air supply.
The fundamental disconnect for a "green" data center is that the Facilities team pay for the electricity, but it is the IT department that makes decisions that impact its use. The PG&E rebates reward IT departments for making better decisions. The best metric available is"Power Usage Effectiveness" or [PUE], which is calculated by dividing total energy consumed in the data center, divided by energy consumed by the IT equipment itself.Typical PUE runs around 3.0 which means for every Watt used for servers, storage or network switches, another 2 Watts are used for power, cooling, and facilities. Companies are tryingto reduce their PUE down to 1.6 or so. The lower the better, and 1.0 is the ideal.The problem is that changing the data center infrastructure is as difficult as replacingthe phone system or your primary ERP application.
While California has [Title 24], stating energy efficiency standards for both residential and commercial buildings, it does notapply to data centers. PG&E is working to add data center standards into this legislation.
The two speakers also covered Data Center [bogeymans], unsubstantiated myths that prevent IT departments fromdoing the right thing. Here are a few examples:
Power cycles - some people believe that x86 servers can typically only handle up to 3000 shutdowns, and so equipment is often left running 24 hours a day to minimize these. Most equipment is kept less than 5 years (1826 days), so turning off non-essential equipment at night, and powering it back on the next morning, is well below this 3000 limit and can greatly reduce kWh.
Dust - many are so concerned about dust that they run extra air-filters which impactsthe efficiency of cooling systems air flow. New IT equipment tolerates dust much betterthan older equipment.
Humidity - Mark had a great story on this one. He said their "de-humidifier" broke,and they never got around to fixing it, and they went years without it, realizing they didn't need to de-humidify.
The session wrapped up with some "low hanging fruit", items that can provide immediate benefit with little effort:
Cold-aisle containment--Why are so few data centers doing this?
Colocation providers need to meter individual clients' energy usage -- IBM offers the instrumentation and software to make this possible
Air flow management--Simply organizing cables under the floor tiles could help this.
Virtualization and Consolidation.
High-efficiency power supplies
Managing IT from a Business Service Perspective
The "other" future of the data center is to manage it as a set of integrated IT services,rather than a collection of servers, storage and switches.IT Infrastructure Library (ITIL) is widely-accepted as a set of best practices to accomplish this "service management" approach. The presenter from ASG Software Solutions presented their Configuration Management Data Base (CMDB) and application dependency dashboard. Theyhave some customers with as many as 200,000 configuration items (CIs) in their CMDB.
The solution looked similar to the IBM Tivoli software stack presented earlier this yearat the [Pulse conference].Both ASG and IBM "eat their own dog food", or perhaps more accurately "drink their own champagne", using these software products to run their own internal IT operations.
For many, the future of a "green" data center managed as a set of integrated service are years away, but the technologies and products are available today, and there is no reasonto postpone these projects any longer than necessary. For more about IBM's approach togreen data center, see [Energy EfficiencySolutions]. You can also take IBM's[IT Service Management self-assessment] to help determine whichIBM tools you need for your situation.
IBM is hosting a webcast about storage for SAP Environments. Learn how integrated IBM infrastructure solutions, specifically, customized for your SAP environments, can help lower your business costs, increases productivity in SAP development and test tasks, and improve resource utilization. This will include discussion of archive solutions with WebDAV, ArchiveLink and DR550;IBM Business Intelligence (BI) Accelerator; IBM support for SAP [Adaptive Computing]; and performance benchmark results. The session is intended for SAP and storage administrators, IT directorsand managers.

It has always been the case in fast pace technology areas that you can't tell the players without a program card, andthis is especially true for storage.
When analyzing each acquistion move, you need to think of what is driving it. What are the motives?Having been in the storage business 20 years now, and seen my share of acquisitions, both from within IBM,as well as competition, I have come up with the following list of motives.
Although slavery was abolished in the US back in the 1800's, and centuries earlier everywhere else, many acquisitionsseem to be focused on acquiring the people themselves, rather than the products or client list. I have seen statistics such as "We retained 98% of the people!" In reality, these retentions usually involve costly incentives,sign-in bonuses, stock options, and the like. Desptie this, people leave after a few years, often because ofpersonality or "corporate culture" clash. For example, many former STK employees seem to be leaving after their company was acquired by Sun Microsystems.
If you can't beat them, join them. Acquisitions can often be used by one company to raise its ranking in marketshare, eliminating smaller competitors. And now that you have acquired their client list, perhaps you can sellthem more of your original set of products!
Symantec had acquired Veritas, which in turn had acquired a variety of other smaller players, and the end result is that they are now #1 backup software provider, even though none of theirproducts holds a candle to IBM's Tivoli Storage Manager. Meanwhile, EMC acquired Avamar to try to get more into the backup/recovery game, but most analysts still find EMC down in the #4 or #5 place in this category.
Next month,Brocade's acquisition of McData should take effect, furthering its marketshare in SAN switch equipment.
Prior to my current role as "brand market strategist" for System Storage, I was a "portfolio manager" where wetried to make sure that our storage product line investments were balanced. This was a tough job, as the investmentshad to balance the right development investments into different technologies, including patent portfolios.Despite IBM's huge research budget, I am not surprised that some clever inventions of new technologies comefrom smaller companies, that then get acquired once their results appear viable.
The last motive is value shift. This is where companies try to re-invent themselves, or find that they are stuck in acommodity market rut, and wish to expand into more profitable areas.
LSI Logic acquisition of StoreAge is a good exampleof this. Most of the major storage vendors have already shifted to software and services to provide customer value,as predicted in 1990's by Clayton Christensen in his book "The Innovator's Dilemma". The rest are still strugglingto develop the right strategy, but leaning in this general direction.
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.
This week, I have been presenting how to do important things without travel. Of course, there are times where you need some boots on the ground, while your support team remains remote.
Last month, fellow co-worker Liz Goodman reached out to me. She was part of a ten-person team that went to Tanzania as part of IBM's[Corporate Service Corps]. Other teams went to Brazil, China, Ghana, Romania, South Africa, The Philippines, Turkey and Vietnam.(I've been to half these other countries, but the closest I have ever been toTanzania was a safari I took in Kenya that included the Masai Mara national park which runsalong the border with Tanzania's Serengheti national park).
Liz was one of the lucky[200 candidates chosen among over 5000 applications] IBM reviews each year for this program. IBM does business in over170 countries, so learning to work in or with emerging growth markets requires a bit of "cultural intelligence".Liz and three others worked with the University of Dudoma [UDOM] to lead some students in adopting a [Moodle] infrastructure based on Linux, Apache, PHP and MySQL [LAMP] platform. She noticed that I had experience with both Moodle and LAMP from [my work with OLPC], and reached out to me for help.I was able to provide some insight, things to watch out for, and how to tackle not just the technical challenges, but a few that many don't consider:
Educational content. Digitizing materials already available in hardcopy, or obtaining digital rights to existing content.
Business Process. Getting the teachers and students to adopt new process and procedures enabled by these new capabilities.
Project Management. Fortunately, Liz is already [PMP-certified], and knows well the importance of managing even a small 4-person, 4-week project like this.
How well did her team do? Liz blogged before, during and after her trip. Read all about iton her blog [Liz Goes To Tanzania]!
Seth Godin has an interesting post titled Times a Million.He recounts how many people determine the fuel savings of higher-mileage cars to be only $300-$900 per year,and that this is not enough to motivate the purchase of a more-efficient vehicle, such as a hybrid orelectric car. Of course, if everyone drove more efficient vehicles, the benefits "times a million" wouldbenefit everyone and the world's ecology.
When I discuss storage-related concepts, many executives mistakenly relate them to the one area of information technologythey know best: their laptop. Let's take a look at some examples:
Information Lifecycle Management
Information Lifecycle Management (ILM) includes classifying data by business value, and then using this to determineplacement, movement or deletion. If you think about the amount of time and effort to review the files on yourindividual laptop, and to manually select and move or delete data, versus the benefits for the individual laptopowner, you would dismiss the concept. Most administrative tasks are done manually on laptops, because automatedsoftware is either unavailable or too expensive to justify for a single owner.
In medium and large size enterprises, automated software to help classify, move and delete data makes a lot of sense.Executives who decide that ILM is not for their data center, based on their experiences with their laptop, are losingout on the "times a million" effect.
Laptops have various controls to minimize the use of battery, and these controls are equally available when pluggedin. Many users don't bother turning off the features and functions they don't need when plugged in, because theyfeel the cost savings would only amount to pennies per day.
Times a million, energy savings do add up, and options to reduce the amount used per server, per TB of data stored, not only save millions of dollars per year, but can also postpone the need to build a new data center, or upgrade the electrical systems in your existing data center.
Backup and Disaster Recovery planning
I am not surprised how many laptops do not have adequate backup and disaster recovery plans. When executives thinkin terms of the time and effort to backup their data, often crudely copying key files to CDrom or USB key, and worryingabout the management of those copies, which copies are the latest, and when those copies can be destroyed, theymight reject deploying appropriate backup policies for others.
Times a million, the collected data stored on laptops could easily be half of your companies emails and intellectual property. Products like IBM Tivoli Storage Manager can manage a large number of clients with a few administrators,keeping track of how many copies to keep, and how long to keep them.
So, next time you are looking at technology or solutions for your data center, don't suffer from "Laptop Mentality". Focus instead on the data center as a whole.

Some people find it surprising that it is often more cost-effective, and power-efficient, to run workloads on mainframe logical partitions (LPARs) than a stack of x86 servers running VMware.
Perhaps they won't be surprised any more. Here is an article in eWeek that explains how IBM isreducing energy costs 80% by consolidating 3,900 rack-optimized servers to 33 IBM System z mainframe servers, running Linux, in its own data centers. Since 1997, IBM has consolidated its 155 strategic worldwide data center locations down to just seven.
I am very pleased that IBM has invested heavily into Linux, with support across servers, storage, software andservices. Linux is allowing IBM to deliver clever, innovative solutions that may not be possible with other operating systems. If you are in storage, you should consider becoming more knowledgeable in Linux.
The older systems won't just end up in a landfill somewhere. Instead, the details are spelled out inthe IBM Press Release:
As part of the effort to protect the environment, IBM Global Asset Recovery Services, the refurbishment and recycling unit of IBM, will process and properly dispose of the 3,900 reclaimed systems. Newer units will be refurbished and resold through IBM's sales force and partner network, while older systems will be harvested for parts or sold for scrap. Prior to disposition, the machines will be scrubbed of all sensitive data. Any unusable e-waste will be properly disposed following environmentally compliant processes perfected over 20 years of leading environmental skill and experience in the area of IT asset disposition.
Whereas other vendors might think that some operational improvements will be enough, such as switching to higher-capacity SATA drives, or virtualizing x86 servers, IBM recognizes that sometimes more fundamental changes are required to effect real changes and real results.
Continuing this week's coverage of the 27th annual [Data Center Conference] I attended some break-out sessions on the "storage" track.
Effectively Deploying Disruptive Storage Architectures and Technologies
Two analysts co-presented this session. In this case, the speakers are using the term "disruptive" in the [positive sense] of the word, as originally used by Clayton Christensen in hisbook[The Innovator's Dilemma], andnot in the negative sense of IT system outages. By a show of hands,they asked if anyone had more storage than they needed. No hands went up.
The session focused on the benefits versus risks of new storage architectures, and which vendors they felt would succeed in this new marketplace around the years 2012-2013.
By electronic survey, here were the number of storage vendors deployed by members of the audience:
14 percent - one vendor
33 percent - two vendors, often called a "dual vendor" strategy
24 percent - three vendors
29 percent - four or more storage vendors
For those who have deployed a storage area network (SAN), 84 percent also have NAS, 61 percent also have some form or archive storage such as IBM System Storage DR550, and 18 percent also have a virtual tape library (VTL).
The speaker credited IBM's leadership in the now popular "storage server" movement to the IBM Versatile Storage Server [VSS] from the 1990s, the predecessor to IBM's popular Enterprise Storage Server (ESS). A "storage server" is merely a disk or tape system built using off-the-shelf server technology, rather than customized [ASIC] chips, lowering thebarriers of entry to a slew of small start-up firms entering the IT storage market, and leading to newinnovation.
How can a system designed for now single point of failure (SPOF) actually then fail? The speaker convenientlyignored the two most obvious answers (multiple failures, microcode error) and focused instead on mis-configuration. She felt part of the blame falls on IT staff not having adequate skills to deal with the complexities of today's storage devices, and the other part of the blame falls on storage vendors for making such complicated devices in the first place.
Scale-out architectures, such as IBM XIV and EMC Atmos, represent a departure from traditional "Scale-up" monolithic equipment. Whereas scale-up machines are traditionally limited in scalability from their packaging, scale-out are limited only by the software architecture and back-end interconnect.
To go with cloud computing, the analyst categorized storage into four groups: Outsourced, Hosted, Cloud, and Sky Drive. The difference depended on where servers, storage and support personnel were located.
How long are you willing to wait for your preferred storage vendor to provide a new feature before switching to another vendor? A shocking 51 percent said at most 12 months! 34 percent would be willing to wait up to 24 months, and only 7 percent were unwilling to change vendors. The results indicate more confidence in being able to change vendors, rather than pressures from upper management to meet budget or functional requirements.
Beyond the seven major storage vendors, there are now dozens of smaller emerging or privately-held start-ups now offering new storage devices. How willing were the members of the audience to do business with these? 21 percent already have devices installed from them, 16 percent plan to in the next 12-24 months, and 63 percent have no plans at all.
The key value proposition from the new storage architectures were ease-of-use and lower total cost of ownership.The speaker recommended developing a strategy or "road map" for deploying new storage architectures, with focus on quantifying the benefits and savings. Ask the new vendor for references, local support, and an acceptance test or "proof-of-concept" to try out the new system. Also, consider the impact to existing Disaster Recovery or other IT processes that this new storage architecture may impact.
Tame the Information Explosion with IBM Information Infrastructure
Susan Blocher, IBM VP of marketing for System Storage, presented this vendor-sponsored session, covering theIBM Information Infrastructure part of IBM's New Enterprise Data Center vision. This was followed by BradHeaton, Senior Systems Admin from ProQuest, who gave his "User Experience" of the IBM TS7650G ProtecTIER virtual tape library and its state-of-the-art inline data deduplication capability.
Best Practices for Managing Data Growth and Reducing Storage Costs
The analyst explained why everyone should be looking at deploying a formal "data archiving" scheme. Not just for "mandatory preservation" resulting from government or industry regulations, but also the benefits of "optional preservation" to help corporations and individual employees be more productive and effective.
Before there were only two tiers of storage, expensive disk and inexpensive tape. Now, with the advent of slower less-expensive SATA disks, including storage systems that emulate virtual tape libraries, and others that offer Non-Erasable, Non-Rewriteable (NENR) protection, IT administrators now have a middle ground to keep their archive data.
New software innovation supports better data management. The speaker recalled when "storage management" was equated to "backup" only, and now includes all aspects of management, including HSM migration, compliance archive, and long term data preservation. I had a smile on my face--IBM has used "storage management" to refer to these other aspects of storage since the 1980s!
The analyst felt the best tool to control growth is the "Delete" the data no longer needed, but felt that nobody uses Storage Resource Management (SRM) tools needed to make this viable. Until then, people willchose instead to archive emails and user files to less expensive media.The speaker also recommended looking into highly-scalable NAS offerings--such as IBM's Scale-Out File Services (SoFS), Exanet, Permabit, IBRIX, Isilon, and others--when fast access to files is worth the premium price over tape media.The speaker also made the distinction between "stub-based" archiving--such as IBM TSM Space Manager, Sun's SAM-FS, and EMC DiskXtender--from "stub-less" archive accomplished through file virtualization that employes a global namespace--such as IBM Virtual File Manager (VFM), EMC RAINfinity or F5's ARX.
She made the distinction between archives and backups. If you are keeping backups longer than four weeks, they are not really backups, are they? These are really archives, but not as effective. Recent legal precedent no longer considers long-term backup tapes as valid archive tapes.
To deploy a new archive strategy, create a formal position of "e-archivist", chose the applications that will be archived and focus on requirements first, rather than going out and buying compliance storage devices. Try to get users to pool their project data into one location, to make archiving easier. Try to have the storage admins offer a "menu" of options to Line-of-Business/Legal/Compliance teams that may not be familiar with subtle differences in storage technologies.
While I am familiar with many of these best practices already, I found it useful to see which competitiveproducts line up with those we have already within IBM, and which new storage architectures others find mostpromising.
Ideally, every airline would use the most experienced seasoned professional airline pilots money could buy, but some airlines, in an effort to compete on ticket price, may elect instead to have less experienced pilots.Here's a great excerpt:
Airline history lesson 101: It used to be, up until the mid 1980’s, that a young pilot would be hired on at a major carrier, become a flight engineer (FE), and then spend a few years managing the systems of the older-generation airplanes. But he or she was learning all the while. These new “pilots” sat in the FE seat and did their job, all the while observing the “pilots” doing the flying, day in and day out.
The FE’s learned from the seasoned pilots about the real world of flying into the Chicago O’Hares and New York LaGuardias. They learned decision making, delegation, and the reality of “captain’s final authority” as confirmed in the law. When they got the chance to upgrade, they became a copilot. The copilot’s duty was to assist the captain in flying; but even during their time as the new copilot, they had the luxury of the FE looking over their shoulders — i.e., more learning. This three-man-crew concept, now a fond memory in the domestic markets but used predominately in international flying, was considered one more layer of protection. But it’s gone.
To become the public speaker I am today, IBM put me through a variety of speaking classes. I taught high school and college classes to practice in front of groups. But most importantly, I traveled with seasoned colleagues and watched them in action from the front row.I learned how to handle tough questions, how to react to hecklers causing trouble, and how to deal with the unexpected before, during and after each presentation. In addition to speaking skills, I ended up having to learn travel skills, foreign language skills, and a variety of cultural social skills. All part of the job in my line of work.
Likewise, being a storage administrator is an important job, and for some data centers, not something to give lightly to a fresh college graduate. Unless they have had format IT Infrastructure Library [ITIL] certification coursework, I doubt they would understand the processes and disciplines demanded by the typical data center. I have been to accounts where new hires are not allowed to touch production systems for the first two years. Instead they watch the seasoned professionals do their jobs, and are given only access to "sand box" systems that are used for application testing or Quality Assurance (QA). Sadly, I have also been to other accounts where people with no storage experience whatsoever were tossed into the admin pool and let loose with superuser passwords, all in an effort to save money during times of exponential data growth rates, only to pay the price later with outages or lost data.
The parallels between the airline industry and the IT industry are eerie.
