This week, IBM launched the new [IBM Expert Network] that provides presentation materials from subject matter experts. I am honored to be one of the 20-plus experts selected for PRO accounts on SlideShare.Net to help seed this with initial materials.
I have a bit of behind-the-scenes history to share on this. Back in 2008, I first discovered SlideShare.net as an excellent resource to get ideas for presentations. Much like YouTube is for videos and FlickR is for photos, SlideShare.Net is for presentations. In my June 2008 post, [Summer Jobs and the Singularity], I embedded someone's presentation from SlideShare.
This latter one got me in a bit of trouble internally. Neither presentation had anything secret or controversial, so I didn't see the issue. Several other bloggers had asked how I got "permission" to use an external Software-as-a-Service (SaaS) like SlideShare.net for my blog. I never asked for permission! I explained that since IBM's internal Lotus Connections software we use for blogging did not have a feature to embed PowerPoint (PPT) or Open Document Format (ODP) presentations, I chose an external service instead. Yes, I guess I could have converted each page to a JPG or PNG graphic instead, or I could have put the PDF on an FTP download area of the "Files" feature of Lotus Connections, but I chose SlideShare.net instead.
The result? IBM communications decided to make an official list, it's actually three lists. A "white list" of services that we are allowed to use, a "grey list" of services under evaluation or negotiation, and a "black list" of services we are not allowed to use, and sadly Slideshare.Net was on the black list. I protested, argued that unless IBM offered something to replace it, to re-evaluate this external service. I got it back on the "grey list" and now, this week, it is officially on the "white list".
Of course, this probably involved negotiation on EULA terms and conditions, but I am not a lawyer and have no idea what went on behind closed doors to make this happen. I am just glad it did.
On Wikibon, David Floyer has an article titled [SAS Drives Tier 1 to New Levels of Green] that focuses on the energy efficiency benefits of newer Serial-Attach SCSI (SAS) drives over older Fibre Channel (FC) drives. This makes sense, as R&D budgets have been spent on making newer technologies more "green".
Of course, people might consider this an [apples-to-oranges] comparison. Not only are we changing from FC to SAS technology, we are also changing from 3.5-inch drives to small form factor (SFF) 2.5-inch drives. It seems odd to specify 2000 drives, when only two of the five scale up to that level. Few systems in production, from any vendor, have more than 1000 drives, so it would have seemed that would have been a fairer comparison.
However, Hu's conclusion that the combination of SAS and SFF provides better performance and energy efficiency for both IBM DS8800 and HDS VSP than FC-based alternatives from any vendor seems reasonably supported by the data.
Meanwhile, fellow blogger David Merrill (HDS) pokes fun at IBM DS8800 in Figure 2 in his post [Winner o’ the green]. This second comparison was for 4PB of raw capacity, which 4 of the 5 can handle easily using 2TB SATA drives, but the DS8800 is based on SAS technology and does not support 2TB SATA drives. A performance-oriented configuration with four distinct DS8800 boxes employing 600GB SAS drives is used instead, causing the data for the DS8800 to stick out like a sore thumb, or perhaps more intentionally as a middle finger.
The main take-away here is that IBM offers both the DS8700 for capacity-optimized workloads, and the DS8800 for performance-optimized workloads. Some competitors may have been spreading FUD that the DS8700 was withdrawn last month, it wasn't. As you can see from the data presented, there are times where a DS8700 might be more preferable than a DS8800, depending on the type of workloads you plan to deploy. IBM offers both, and will continue to support existing DS8700 and DS8800 units in the field for many years to come.
This year marks the 10 year anniversary of IBM's introduction of LTO tape technology. IBM is a member of the Linear Tape Open consortium which consists of IBM, HP and Quantum, referred to as "Technology Provider Companies" or TPCs. In an earlier job role, I was the "portfolio manager" for both LTO and Enterprise tape product lines.
Today, we held a celebration in Tucson, with cake and refreshments.
IBM Executives Doug Balog, IBM VP of Storage Platform, and Sanjay Tripathi, the new IBM Director and Business Line Executive for Tape, VTL and Archive systems, presented the successes of LTO tape over the past 10 years.
To date over 3.5 million LTO tape drives, and over 150 million LTO tape media cartridges have been shipped which is a testament to the remarkable marketplace acceptance of the technology.
In honor of this event, I decided to interview Bruce Master, IBM Senior Program Manager for Data Protection Systems, about this 10 year anniversary.
10 years of LTO technology is a great milestone. How is this especially significant to IBM and its clients?
According to IDC data, IBM has held the #1 leader position in market share for total world wide branded tape revenue for over 7 years and that IBM is still #1 in branded midrange tape revenue which includes the LTO tape technologies. IBM was the first drive manufacturer to deliver LTO-1 drives, back in September 2000, the first to deliver tape drive encryption to the marketplace on LTO-4 drives, and is shipping LTO generation 5 drives and libraries. IBM is the author of the new Linear Tape File System (LTFS) specification that has been adopted by the TPCs. This file system revolutionizes how tape can be used as if it were a giant 1.5 terabyte removable USB memory stick with the capability to be accessed with directory tree structures and drag and drop functionality. With LTO's built-in real-time compression, a single tape cartridge can hold up to 3TB of data.
The Linear Tape File System has been getting a lot of attention. Where can we learn more about it?
Why is tape still a critical part of a storage infrastructure?
Tape is low cost and provides critical off-line portable storage to help protect data from attacks that can occur with on-line data. For instance, on-line data is at risk of attack from a virus, hacker, system error, disgruntled employee, and more. Since tape is off-line, not accessible by the system, it protects against these forms of corruption. LTO technology also provides write-once read-many (WORM) tape media to help address compliance issues that specify non-erasable, non-rewriteable (NENR) storage, hardware encryption to secure data, as well as a low cost long term archive media. When data cools off, or becomes infrequently accessed, why keep it on spinning disk? Move it to tape where it is much greener and lower cost. A tape in a slot on a shelf consumes minimal energy.
So tape is not dead?
Ha! Far from it. Seems like disk-only "specialty shop" storage vendors that don’t have tape in their sales portfolio are the ones that propagate that myth. In reality, storage managers are tasked with meeting complex objectives for performance, compliance, security, data protection, archive and total cost of ownership. Optimally, a blend of disk and tape in a tiered infrastructure can best address these objectives. You can’t build a house with just a hammer. IBM has a rich tool kit of storage offerings including disk, tape, software, services and deduplication technologies to help clients address their needs.
Do you have an example of a client who was saved by tape?
Yes indeed. Estes Express, a large trucking firm, was hit by a hurricane that flooded their data center and destroyed all systems. Fortunately the company survived because the night before they had backed up all data on to IBM tape and moved the cartridges offsite! The company survived and has since implemented a best practices data protection strategy with a combination of disk-to-disk-to-tape (D2D2T) using LTO tape at the primary site, and a remote global mirrored site that is also backed up to LTO tape.
So tape saved the day. What is the outlook for tape innovation in the future?
The future is bright for tape. Earlier this year, IBM and Fujifilm were able to [demonstrate a tape density achievement] that could enable a native 35TB tape cartridge capacity! This shows a long roadmap ahead for tape and a continued good night’s sleep for storage managers knowing that their precious data will be safe.
Of course, LTO tape is just one of the many reasons IBM is a successful and profitable leader in the IT storage industry. Doug Balog talked about his experiences in London for the [October 7th launch] of IBM DS8800, Storwize V7000 and SAN Volume Controller 6.1. Sanjay Tripathi showed recent successes with IBM's ProtecTIER Data Deduplication Solution and Information Archive products.
I would like to thank Bruce Master for his time in completing this interview. To learn more about IBM tape and storage offerings, visit [ibm.com/storage].
Each quarter since 2006, the [IBM Migration Factory] team has tallied the number of clients who have moved to IBM severs and storage systems from competitive hardware. We'll I've just seen the latest numbers, for the third quarter of 2010, and it looks like we set a new quarterly record with nearly 400 total migrations to IBM from Oracle/Sun and HP.
It's clear that companies and governments worldwide are seeing greater value in IBM systems, while Oracle and HP watch their customer bases erode. In just this past 3Q 2010, nearly 400 clients have moved over to IBM -- almost all of them from Oracle/Sun and HP. Of these, 286 clients migrated to IBM Power Systems, running AIX, Linux and IBM i operating systems, from competitors alone -- nearly 175 from Oracle/Sun and nearly 100 from HP. The number of migrations to IBM Power Systems through the first three quarters of 2010 is nearly 800, already exceeding the total for all of last year by more than 200.
Let's do the math.... Since IBM established its Migration Factory program in 2006, more than 4,500 clients have switched to IBM. More than 1,000 from Oracle/Sun and HP joined the exodus this year alone. In less than five years, almost 3,000 of these clients -- including more than 1,500 from Oracle/Sun and more than 1,000 from HP -- have chosen to run their businesses on IBM's Power Systems. That's more than a client per day making the move to IBM!
And as the servers go, so goes the storage. Clients are re-discovering IBM as a server and storage powerhouse, offering a strong portfolio in servers, disk and tape systems, and how synergies between servers and storage can provide them real business benefits.
Adding it all up, it's clear that IBM's multi-billion dollar investment in helping to build a smarter planet with workload-optimized systems is paying off -- and that, more and more, clients are selecting IBM over the competition to help them meet their business needs.
This week I am in New York City to meet with clients, IBM Business Partners, Independent Software Vendors (ISV) and Industry Solution Resellers (ISR). I'll be at IBM's [Wall Street Center of Excellence]. IBM has over 120 client centers worldwide.
"How can I participate in IBM's Smarter Planet, specifically Smarter Cities?"
With a lot of college students graduating next month, I thought this would be a good question to answer.
Apply for a Job at IBM
The best way to participate in IBM Smarter Cities is to get a job within IBM, and then get assigned to one of the many IBM Smarter Cities projects. Visit IBM's [Employment Page] to learn why IBM is recognized as one of the top 50 most attractive employers in the world. Mention "Smarter Cities" on your Resume so it can be routed to the appropriate manager.
Join the Conversation
Another way to participate in Smarter Cities is to "join the conversation". Each of IBM's 25 different programs has folks that are focused on that area, with blogs, forums and case studies. Here is the conversations page for [Smarter Cities]. Watch the videos at ibm.com/theSmarterCity]. Play IBM's [City One], IBM's Smarter Planet for game for Smarter Cities. Provide IBM feedback on any ideas you might have to help make cities smarter.
You can also join in one of the many upcoming [IBM Jam events]. Jams are not restricted to generating business ideas. Their methods, tools and technology can also be applied to social issues. In 2005, over three days, the Government of Canada, UN-HABITAT and IBM hosted Habitat Jam. Tens of thousands of participants - from urban specialists, to government leaders, to residents from cities around the world - discussed issues of urban sustainability. Their ideas shaped the agenda for the UN World Urban Forum, held in June 2006. People from 158 countries registered for the jam and shared their ideas for action to improve the environment, health, safety and quality of life in the world's burgeoning cities.
Buy Products and/or Services from IBM
IBM has the resources to help the planet in so many ways that NGOs and non-profit agencies only dream of. With IBM's advocacy for causes like global public education, universal healthcare, and improved infrastructures, people often forget that IBM is not itself a non-profit organization. IBM has learned early on that creating value for the world can also be good business. The more people buy from IBM, the more skills and resources IBM will have to solve the world's toughest challenges.
It's Tuesday, and you know what that means... IBM Announcements!
IBM System Storage ProtecTIER
Today, IBM refreshed its IBM System Storage ProtecTIER data deduplication family with new hardware and software. On the hardware side, The [TS7650G gateway] now has 32 cores and 64GB RAM. The [TS7650 Appliance] now has 24 cores and 64GB of RAM, and the [TS7610 Appliance Express] has 4 cores and up to 16GB of RAM.
On the software side, all of these now support Symantec's proprietary "OpenStorage" OST API. This applies across the board, from the [Enterprise Edition], [Appliance Edition], and the [Entry Edition]. For those using Symantec NetBackup as their backup software, the OST API can provide advantages over the standard VTL interface.
IBM Systems Director Storage Control
The second announcement has an interesting twist. I could file this in my "I Told You So" folder. Offiically, it's called the [Cassandra Complex], where you accurately predict how something will turn out, but being unable to convince anyone else of what the future holds.
About ten years ago, I was asked to be lead architect of a new product to be called IBM TotalStorage Productivity Center, which was later renamed to IBM Tivoli Storage Productivity Center. This would combine three projects:
Tivoli Storage Resource Manager (TSRM)
Tivoli SAN Manager (TSANM)
Multiple Device Manager (MDM)
The first two were based on Tivoli's internal GUI platform, and the MDM was a plug-in for IBM Systems Director. I argued that administrators would want everything on a single pane of glass, and that we should bring all the components under a common GUI platform, such as IBM Systems Director. Unfortunately, management did not agree with me on that, and preferred instead to leave each interface alone to minimize development effort. The only "unification" was to give them all similar sounding names, four components packaged as single product:
Productivity Center for Data (formerly TSRM)
Productivity Center for Fabric (formerly TSANM)
Productivity Center for Disk (formerly MDM)
Productivity Center for Replication (formerly MDM)
While this management decision certainly allowed version 1 to hit the market sooner, this was not a good "first impression" of the product for many of our clients.
In 2002, IBM acquired Trellisoft, Inc. which replaced the internally-developed TSRM with a much better interface, but again, this was different GUI than the other components. A "launcher" was created that would launch the various disparate interfaces for each component for Version 2. At this point, we have different development teams scattered in five locations, with the first two components being developed by the Tivoli software team, and the other two components being developed by the System Storage hardware team.
Often times, when a technical lead architect and management do not agree, things do not end well. The lead architect has to leave the product, and management is forced to take alternative actions to keep the product going. In my case, management considered the idea of a common GUI as an expensive "nice-to-have" luxury we could not afford, but I considered this a "must-have". I moved on to a new job within IBM, and management, unable to continue without my leadership, gave up and handed the entire project over to the Tivoli Software team.
The Tivoli Software team took a whiff at the pile of code and agreed that it stunk. Dusting off my original design documents, they pretty much discarded most of the code and re-wrote much from scratch, with a common database, common app server, and common GUI platform. Unfortunately, Productivity Center for Replication was held up waiting for some hardware prerequisites, but the other three components would be packaged together as "Productivity Center v3 - Standard Edition" and was a big improvement over the prior versions.
In Version 4, TotalStorage Productivity Center was renamed to Tivoli Storage Productivity Center, and the Replication component was brought into the mix. A scaled-down version packaged as Productivity Center "Basic Edition" was made available as a hardware appliance named "System Storage Productivity Center" or SSPC. The idea was to provide a pre-installed 1U-high hardware console that had the basic functions of Productivity Center, with the option to upgrade to the full Tivoli Storage Productivity Center with just license keys.
So, now, years later, management recognizes that a common GUI platform is more than just a "nice-to-have". IBM now support three very specific use cases:
1. Administration for a single product
For small clients who might have only a single IBM product, IBM is now focused on making the GUI browser-based, specifically to work with the Mozilla Firefox browser, but any similar browser should work as well. The new IBM Storwize V7000 GUI is a good example of this.In this case, the browser serves as the common GUI platform.
2. Administration for both servers and storage devices
For mid-sized companies that have administrators managing both servers and storage, IBM announced this month the new [IBM Systems Director Storage Control v4.2.1] plug-in, which provides Tivoli Storage Productivity Center "Basic Edition" support. This allows admins already familiar with IBM Systems Director for managing their servers to also manage basic storage functions. This is the "I Told You So" moment, connecting server and storage administration under the IBM Systems Director management platform makes a lot of sense, it did when I came up with the idea 10 years ago! Hmmmm?
3. Administration for just the storage environment
For larger companies big enough to have separate server and storage admin teams, IBM continues to offer the full Tivoli Storage Productivity Center product for the storage admins. The most recent release enhanced the support for IBM DS8000, SVC, Storwize V7000 and XIV storage systems.
Today, analysts consider IBM's [Tivoli Storage Productivity Center] one of the leading products in its category. I am glad my original vision has finally come to life, even though it took a while longer than I expected.

To make true advances in any industry or field requires forward thinking—as well as industry insight and experience. It can't be done just by packaging a bag of piece parts and putting a new label on it. But forward thinkers are putting smarter, more powerful technology to uses that were once unimaginable -- either in scale or in progress.
The graphics developed for the IBM Smarter Planet vision are interesting. This one for Infrastructure includes images relating to public utilities, like gas, water and electricity, clouds representing cloud computing, green forests representing the need for energy efficiency and reducing carbon footprint to fight global warming, roads, representing the intricate transportation and traffic systems, highways and city streets that connect us all together, and a printed circuit board, representing the Information Technology that makes all of this possible.
Ironically, I didn't even know I made the final cut until I got three, yes three, separate requests for interviews about it. I already reached the "million hits" milestone. Other people track these things for me, so it will be interesting how much additional traffic my latest [15 minutes of fame] will generate.
Infrastructure is just one of the 25 different areas that IBM's vision for a Smarter Planet is trying to address, including the need for smarter buildings, smarter cities, smarter transportation systems, smarter energy grids, smarter healthcare and public safety, and smarter governments.
In his blog post, [The Lure of Kit-Cars], fellow blogger Chuck Hollis (EMC) uses an excellent analogy delineating the differences between kit-cars you build from parts, versus fully-integrated systems that you can drive off the car dealership showroom lot. The analogy holds relatively well, as IT departments can also build their infrastructure from parts, or you can get fully-integrated systems from a variety of vendors.
Is this what your data center looks like?
Certainly, this debate is not new. In my now infamous 2007 post [Supermarkets and Specialty Shops], I explained that there were clients that preferred to get their infrastructure from a single IT supermarket, like IBM or HP, while others were lured into thinking that buying separate parts from butchers, bakers and candlestick makers and other specialty shops was somehow a better idea.
Chuck correctly explains that in the early years of the automobile industry, before major car manufacturers had mass-production assembly lines, putting a car together from parts was the only way cars were made. Today, only the few most avid enthusiasts build cars this way. The majority get cars from a single seller and drive away. In my post [Resolving the Identity Crisis], I postulated that EMC appeared to be trying to shed itself of the "disk-only specialty shop" image and over to be more like IBM. Not quite a full IT Supermarket, but perhaps more like a [Trader Joe's] premium-priced retailer.
(If you find that EMC's focus on integrated systems appears to be a 180-degree about-face from their historical focus on selling individual best-of-breed products, see my previous discussion of Chuck's contradictions in my blog post: [Is Storage the Next Confusopoly].)
While companies like EMC might be making this transition, there is a lot of resistance and inertia from the customer marketplace. I agree with Chuck, companies should not be building kit-cars or IT infrastructures from parts, certainly not from parts sold from different vendors. In my post [Talking about Solutions not Products], I explained how difficult it was to change behavior. CIOs, IT directors and managers need to think differently about their infrastructure. Let's take a quick look at some choices:
Following Chuck's argument, it makes no sense to build a "kit-car" combining Oracle/Sun servers with EMC storage. Oracle would argue it makes more sense to run on integrated systems, business logic on their "Exalogic" system, and database processing on their "Exadata". Benchmark after benchmark, however, IBM is able to demonstrate that Oracle applications and databases run faster on IBM systems. Customers that want to run Oracle applications can run either on a full Oracle stack, or a full IBM stack, and both do better than a kit-car including EMC parts.
HP has been working hard to keep up with IBM in this area. With their their partnership with Microsoft, and acquisitions of EDS, 3Com and 3PAR, they can certainly make a case for getting a full HP stack rather than a kit-car mixing HP servers with EMC disk storage. The problem is that HP is focused on a converged infrastructure for private cloud computing, but Microsoft is focused on Azure and public cloud computing. It will be interesting when these two big companies sort this out. Definitely watch this space.
If you squint your eyes and focus on the part of the world that only has x86 machines, then Dell can be seen as an IT supermarket. In my post about [Entry-Level iSCSI Offerings], I discuss how Dell's acquisition of EqualLogic was a signal that it was trying to get away from selling EMC specialty shop products, and building up its own set of offerings internally.
Cisco is new on the server scene, but has already made quite a splash. Here, I have to agree with Chuck's logic: the only time it makes sense to buy EMC disk storage at all is when it is part of an integrated "V-block". This is not really an IT supermarket situation, instead you park your car at the "Acadia Mini-Mall" and get what you need from Trader Joe's, Cisco UCS, and VMware stores.
But wait, if what you want is running VMware on Cisco servers, you might be better off with IBM System Storage N series or NetApp storage. In his blog post about [Enhanced Secure Multi-Tenancy], fellow Blogger Val Bercovici (NetApp) provides a convincing argument of why Cisco and VMware run better on an "N-block" rather than a "V-block". IBM N series provides A-SIS deduplication, and IBM Real-time Compression can provide additional capacity and performance improvements. That might be true, but whether you get your storage from EMC, NetApp or IBM, to me, you are still working with three different vendors in any case.
Of course, following Chuck's logic, it makes more sense for people with IBM servers, whether they be mainframes, POWER systems or x86 machines, to integrate these with IBM storage, IBM software and IBM services. IBM is the leading reseller of VMware, but also has a lot of business with Microsoft Hyper-V, Citrix Xen, Linux KVM, PowerVM, PR/SM and z/VM. While IBM has market leading servers, disk and tape systems, to compete for those RFP bids that just ask for one component or another, it prefers to sell fully-integrated systems, which IBM has been doing successfully since the 1950s.
Back in 2007, I mentioned how IBM's fully-integrated InfoSphere Balanced Warehouse [Trounced HP and Sun]. For business analytics, IBM offers the fully-integrated [IBM Smart Analytics Systems]. Today, IBM expanded its line of fully-integrated private cloud service delivery platforms with the announcement of the [IBM CloudBurst for on Power Systems], which does for POWER7 what the IBM CloudBurst for System x, Oracle Exalogic, or Acadia's V-block, do for x86.
IBM estimates that private clouds built on Power systems can be up to 70 percent less expensive than stand alone x86 servers.
Before he earned his PhD in Mechanical Engineering, my father was a car mechanic. I spent much of my teenage years covered in grease, helping my father assembling cars, lifting engines, and rebuilding carburetors. Certainly this was good father-son time, and I certainly did learn something in the process. Like the automobile industry, the IT industry has matured, and it makes no financial sense to build your own IT infrastructure from parts from different vendors.

If you think this is the first time a company like IBM has pulled shenanigans with product names like this, think again. Here are a few posts that might refresh your memory:
In my September 2006 post, [A brand by any other name...] I explain that I started blogging specifically to promote the new "IBM System Storage" product line name, part of the "IBM Systems" brand resulting from merging the "eServer" and "TotalStorage' brands.
In my January 2007 post, [When Names Change], I explain our naming convention for our disk products, including our DS family, SAN Volume Controller and N series.
In my February 2008 post, [Getting Off the Island], I cover how the x/p/i/z designations came about for our various IBM server product lines.
But what about acquisitions? When [IBM acquired Lotus Development Corporation], it kept the "Lotus" brand. New products that fit the "collaboration" function were put under the Lotus brand. I think most people can accept this approach.
But have we ever seen an existing product renamed to an acquired name?
In my post January 2009 post
[Congratulations to Ken on your QCC Milestone], I mentioned that my colleague Ken Hannigan worked on an internal project initially called "Workstation Data Save Facility" (WDSF) which was changed to "Data Facility Distributed Storage Manager" (DFDSM), then renamed to "ADSTAR Distributed Storage Manager" (ADSM), and finally renamed to the name it has today: IBM Tivoli Storage Manager (TSM).
Readers reminded me that [IBM acquired Tivoli Systems, Inc.] in 1996, so TSM could not have been an internally developed product. Ha! Wrong! Let's take a quick history lesson on how this came about:
In the late 1980s, IBM Almaden research had developed a project to backup personal computers and workstations, which they called "Workstation Data Save Facility" or WDSF.
This was turned over to our development team, which immediately discarded the code, and wrote from scratch its replacmeent, called Data Facility Distributed Storage Manager (DFDSM), named similar to the Data Facility products on the mainframe (DFP, DFHSM, DFDSS). As a member of the Data Facility family, DFDSM didn't really fit. The rest processed mainframe data sets, but DFDSM processed Windows and UNIX files. That a version of DFDSM server was available to run on the mainframe was the only connection.
Then, in the early 1990s, there were discussions of possibly splitting IBM into a bunch of smaller "Baby Blues", similar to how [AT&T was split into "Baby Bells"], and how Forbes and Goldman Sachs now want to split Microsoft into [Baby Bills]. IBM considered naming the storage spin-off as ADSTAR, which stood for "Advanced Storage and Retrieval."
Pre-emptively, IBM renamed DFDSM to "ADSTAR Distributed Storage Manager" or ADSM.
Fortunately, in 1993, IBM brought a new sheriff to town, Lou Gerstner, who quickly squashed any plans to split up IBM. He quickly realized that IBM's core strength was building integrated stacks, combining systems, software and services to solve business problems.
In 1996, IBM acquired Tivoli Systems, Inc. to expand its "Systems Management" portfolio, and renamed ADSM over to IBM Tivoli Storage Manager, since "storage management" is an essential part of "systems management". Later, IBM TotalStorage Productivity Center would be renamed to "IBM Tivoli Storage Productivity Center."
I participated in five months of painful meetings to figure out what to name our new internally-developed midrange disk system. Since it ran SAN Volume Controller software, I pushed for keeping the SVC designation somehow. We considered DS naming convention, but the new midrange product would not fit between our existing DS5000 and DS6000 numbering scheme. A marketing agency we hired came up with nonsensical names, in the spirit of product names like Celerra, Centera and CLARiiON, using name generators like [Wordoid]. Luckily, in the nick of time, IBM acquired Storwize for its compression technology, and decided that Storwize as a name was way better fit than any of the names we came up with already.
However, the new IBM Storwize V7000 midrange product had nothing in common with the appliances acquired from Storwize, the company, so to avoid confusion, the latter products were renamed to [IBM Real-time Compression]. Fellow blogger Steven Kenniston, the Storage Alchemist from Storwize fame now part of IBM from the acquisition, gives his perspective on this in his post [Storwize – What is in a Name, Really?]. While I am often critical of the names and terms IBM uses, I have to say this last set of naming decisions makes a lot of sense to me and I support it wholeheartedly.
