This week, I am attending the [InterConnect Conference] in Las Vegas, Feb 21-25, 2016. This is IBM's premier Cloud & Mobile conference for the year.
4955A IBM and Box: Delivering Hybrid Solutions for Enterprise Content Management
Rich Howarth, IBM VP of Enterprise Content Management, and Rand Wacker, Vice President at Box, co-presented this session on the [IBM-and-Box partnership], integrating content management, social and analytics products with the Box cloud content management offering to enable enterprise customers to deploy hybrid solutions leveraging the best of their existing on-premise technologies along with new cloud technologies.
IBM and Box are partnering to re-imagine content management, case management and governance in the cloud. For example, IBM StoredIQ that scans various data sources to find documents and evidence needed to defend yourself against lawsuits can be run against files uploaded to Box.
On a personal note, the IBM Tucson Executive Briefing Center where I work now uses Box to upload presentation files that are then sent to the client attendees.
6524A The Role of Tape in a Cloud-Based World for Economical and Secure Data Retention
This was a 50/50 session. The first half was presented by Shawn Brume, IBM, that covered Linear Tape File System (LTFS) and IBM Spectrum Archive.
Like the cloud, tape has made great strides -- evolving independently in capacity, durability and data access capability while maintaining its economic benefits. As a result, today's tape is just as well suited to cloud service providers as it is to the enterprises and midsize organizations that rely on it to support their production and data protection strategies.
If a cloud service provider does not use tape, the provider and its customers are almost guaranteed to experience a long-term cost outlay that is higher than necessary, and will be putting their oldest and most compliance-sensitive data at risk, thanks to a disk-only based MSP model. See how incorporating tape into your storage strategy can reduce costs and improve MSP margins.
How does tape compare to disk for Cloud providers? A [Zettabyte] of data would cost $41 billion USD per year on disk, but only 8 billion USD per year on tape. Electricity for a Zettabyte of data requires 1.2 Gigawatt for disk, but only 300 Megawatt for tape.
For access to files that require a tape mount, an access time to first byte averages 45 seconds, with a worst case around 75 seconds. After that, tape can stream data as fast as the Internet can deliver it, so performance is not an issue beyond first byte access.
The second half was presented by Michael Piltoff, from value-added reseller Champion Solutions Group, covering their latest product called EchoLeaf. This can run on Windows or Linux that attaches to any IBM tape library, and exports the files on those cartridges as NFS or CIFS/SMB.
In other words, the entire library appears as a single mount point or drive letter, and each tape cartridge appears as a sub-directory. This uses IBM Spectrum Archive Library Edition under the covers.
4759A Cloud Storage Success: MSPs and Enterprises Reveal their Secrets
How do you distinguish fact from fiction when it comes to claims made by vendors about storage for cloud? Eric Herzog, IBM Vice President Marketing for IBM Storage Systems, served as emcee for a panel of experts using IBM Storage solutions across different industries for their Hybrid Cloud deployments.
The panel shared their experiences in using various technologies to get the most out of their private and hybrid cloud, discussed how they are building out their next-gen data centers to cope with today's business needs, talked about how they are using flash and software defined storage to place them where they need to be to succeed in the future.
On the panel were:
Richard Spurlock, Cobalt Iron, using PB of storage on Spectrum Scale and Cleversafe
Paul Rafferty, IBM Silverpop, using Spectrum Accelerate with different Cloud providers
Johnny Oldenburg, Tieto Sweden AB, using SVC, Storwize V7000 and FlashSystem
Keith Dobbins, Time Warner Cable/Navisite, over 30 fully-populated XIV storage systems
Here were some of the nuggets of wisdom:
Eliminate the debate between private or public cloud. Consider everything to be a unique shade of Hybrid Cloud.
Get the network right, all data and management control is done through the network in the Cloud
Take an "Outside-In" approach, focusing on the business problems being solved, rather than trying to exploit specific technologies.
Workloads are unpredictable in the Cloud. Cloud can sometimes be unreliable in their response to workload changes. Partner with vendors like IBM to provide support and scalability to handle the unexpected.
Ensure that you comply with government and industry regulations. For example, Payment Card Industry Data Security Standard [PCI-DSS] for credit card transactions.
Use VMware Storage Vmotion and VVols to migrate data from one Cloud to another.
Software defined network (SDN) and Software Defined Storage (SDS) greatly automate the provisioning process, pushing many storage admin tasks down to NOC personnel.
Use tools like Spectrum Control to provide a single-pane-of-glass management of your entire environment.
Build abstraction layers at touch points to avoid being impacted by external changes, and use documented reference architectures to ensure success.
Educate your clients and end-users on what is possible, and what is probable, in the Cloud.
Use "Flash Cache" technologies, such as IBM XIV, Oracle, Spectrum Scale, and VMware.
Analytics can help with "data rationalization", which identifies the business value of the data.
Object Store is a first-class citizen and should seriously be considered for new projects.
5467A My Data is Out of Control! Managing the Lifecycle of Your Data with "Big Storage" Cloud Archive
Jeff Karmiol and Quaid Nasir, both from IBM, presented a technology preview of a deep archive to be launched later this year.
A staggering 80 percent of data is never touched after 90 days of capture or creation. However, the data may need be kept for business, compliance or regulatory reasons.
"Big Storage" offers cloud storage for customers who need to store large amounts of data and retrieve it on-demand at the lowest cost possible. This easy-to-use cloud service provides fast retrieval times with affordable, transparent pricing and retrieval rates.
This service uses standard OpenStack Swift and POSIX interfaces so you don't need to learn any new APIs. Files and objects remain visible while archived, making it easy and affordable to continue to extract business value from your archived data.
This deep archive is located in a secure, IBM-managed data center. How deep? The facility is 350 feet deep under a mountain, which allows that tape cartridges to be kept at constant humidity and 40 degree Fahrenheit temperature.
Multiple resiliency and data protection options will be available. The data can be part of a global namespace, with some data on premises, connected to data migrated to the archive. Data movement can be either manually-initiated or policy-managed.
7256: Blogging 301: The Art of Opinion
"Turbo" Todd Watson and I started blogging 10 years ago, and we have both been ranked in the top-10 bloggers for IBM. He presented a series covering the basics of blogging. This session was a deeper dive into best writing practices and structures for being confident, engaging, and convincing in their writing.
Here are some of his bits of wisdom:
Base your opinions on fact and well-research information.
Educate your readers, without being "preachy"
Generate interest and enthusiasm, and encourage readers to participate
Don't equivocate, pick a position or side of a debate and stick with it
Leave your reader with the next logical step, a call to action, or pointer to additional information
Forrester analysts kicked off the keynote sessions for Day 1 of the Forrester IT Forum 2009 event. The theme for this conference is "Redefining IT's value to the Enterprise."Rather than focusing on blue-sky futures that are decades away, Forrester wants to present instead a blend of pragmatic informationthat is actionable now in the next 90 days along with some forward-looking trends.
If you ask CEOs how well their IT operations are doing, 75 percent will saythey are doing great. However, if you dig down, and ask how their companies are leveraging IT to help generate revenues, reduce costs, improve employee morale, drive profits, improve customer service, or manage risks, then the percentage drops down to 30 to 35 percent.
What are the root causes of this "perception gap" in value between business and IT? Several ideas come to mind:
Some CEOs still consider IT departments as "cost centers". Rather than exploiting technology to help drive the rest of the business, they are seen as a necessary evil, an extension of the accounting department, for example.
Some CEOs consider IT's role as basically "keeping the lights on". They only notice IT when the lights go out, or other business outages caused by disruptions in IT.
IT departments measure themselves in technology terms, not business terms. CEOs and the rest of the senior management team may not be "tech savvy", and the CIO and IT directors may not be "business savvy", resulting in failure to communicate IT's role and value to the rest of the business.
This conference is focused on CIOs and IT professionals, and how they can bridge the tech/business gap. The first two executive keynote presentations emphasized this point.
Bob Moffat, Senior VP and Group Executive, IBM
Bob Moffat (my fifth-line manager, or if you prefer, my boss's boss's boss's boss's boss) is the Senior VP and Group Executive of IBM's Systems and Technology Group that manufactures storage and other hardware. He presented how IBM is helping our clients deploy smarter solutions. Globalization has changed world business markets, has changed the reach of information technology, and has changed our client's needs.To support that, IBM is focused on making the world a smarter planet, instrumented with appropriate sensors, interconnected over converging networks, and intelligent to provide visibility, control and automation.
It's time to rethink IT in light of these new developments, to think about IT in client terms, with business metrics. Bob gave several internal and customer examples, here's one from the City of Stockholm:
Covering nine square miles of Stockholm Sweden, IBM led [the largest project of its kind] for traffic congestion in Europe. To reduce congestion caused by 300,000 vehicles, the City of Stockhold enacted a "congestion fee" with real-time recognition of license plates and a Web infrastructure to collect payments. The analytics, metrics and incentives have paid off. Since August 2007, traffic is reduced 18 percent, a reduction of travel time on inner streets, and a 9 percent increase in "green" vehicles.
In addition to smarter traffic, IBM has initiatives for smarter water, smarter energy, smarterhealthcare, smarter supply chain, and smarter food supply.
Dave Barnes, Senior VP and CIO, United Postal Service (UPS)
Dave Barnes must act as the "trusted advisor" to the rest of the senior management team. UPS delivers packages worldwide. They put sensors on all of the vehicles, not just to know how fast they were driving,but also how often they drove in reverse gear, and sensors on the engines to determine maintenance schedules.Analytics found that driving in reverse was the most dangerous, and by providing this information to the drivers themselves, the drivers were able to come up with their own innovative ways to minimize accidents.This is one role of IT, to provide employees the information they need to enable them to be better at their own jobs.
Dave also mentioned the importance of collaborating across business units. Their "Information Technology Steering Committee (ITSC)" has 15 members, of which only three are from the IT department. This helped deploy social media initiatives within UPS. For example, Twitter has been adopted so that senior management can get unfiltered customer feedback. This is perhaps another key role of IT, to flatten an organization from cultural hierarchies that prevent top brass up in the ivory tower from hearing what is going wrong down on the street. Too often, a customer or client complains to the nearest employee, and this may or may not get passed up accurately along the chain of command. Twitter allowed executives to see what was going on for themselves.
Dave also covered the "Best Neighbor" approach. If you were going to build a deck in your back yard, you might ask your neighbors that have already done this, and learn from their experience. Sadly, this does not happen enough in IT. To address this, UPS has a "Tech Governance Group" that focused on business process across the organization. For example, they improved "package flow", reducing 100 million miles in the past few years.
Lastly, he mentioned that many technologists are "loners". They have a few like that, but try to hire techies who look to team across business units instead. Likewise, they try to hire business people who are somewhat tech savvy. For example, they have encouraged business employees to write their own reports, rather than requesting new reports to be developed by the IT department. The end result, the business people get exactly the reports they want, faster than waiting for IT to do it. Another role for IT is to provide end-users the tools to make their own reports.
(Dave didn't mention what tools these were, but it sounded like the Business Intelligence and Reporting Tools [BIRT] that IBM uses.)
These two sessions were a great one-two punch to the audience of 600 CIOs and IT professionals. First, IBM sets the groundwork for what needs to be done. Then, UPS shows how they did exactly that, adopting a dynamic infrastructure and got great results. This is going to be an interesting week!
Today we watched Barack Obama get inaugurated as the 44th President of the United States, and he reminded all Americans that the power and strength of this country comes through its diversity.To some extent, this is also what gives IBM its power and strength as well. While not quite the orator of President Obama, IBM's own CFO, Mark Loughridge, gave a rousing speech about IBM's 4Q08 and year-end financial results.
In 2008, IBM was not just successful because it had a wide diversity of servers and storage hardware products, but also a diversity of software, and a diversity of service offerings.And lastly, IBM sells to a diversity of clients in different industries, throughout a diversity of markets. While the current economic meltdown might have affected businesses focused on the US and other major markets, IBM did particularly well last year in growth markets, including the so-called BRIC countries (Brazil, Russia, India and China).
IBM's approach to invest in R&D and its nearly 400,000 employees for long-term success continues to pay off. Where "Cash is King", IBM can also afford all those acquisitions and strategic initiatives, positioning the company for a brighter future.
Where there are challenges, IBM finds opportunity.
Well,This is completely off-topic, but now that I have a bluetooth-enabled Thinkpad T60, I have been interested in this new wireless technology. I have a bluetooth cell phone, a bluetooth wireless headset, and my thinkpad, and they all work together seemlessly. I am able to speak on my cell phone through my headset, listen to music and videos on my laptop through my headset, and even dial in to the IBM network through my cell phone, all without any cables!
A variation of the Wi-Fi soup-cantenna has emerged to intercepting bluetooth signals. Check out this coolBlueSniper Rifle
I am saddened to learn that one of my favorite comedians, [George Carlin],passed away yesterday. He was famous for a skit about "seven words" you could not say on Television.A few of those came to mind in the response I got from my post[Yes, Jon,There is a mainframe that can help replace 1500 x86 servers, which attempted to provide an answerto a simple question about the IBM System z10 Enterprise Class (EC) mainframe.
Jon: So, where is the 1500 number coming from? Tony: I’ll investigate and get back to you.
My post tried to explain how IBM estimated that number. However, my fellow blogger from Sun, Jeff Savit, posted on his blog [No, there isn't a Santa Claus] in response. (If Sun'sshareholders are expecting anything other than a [lump of coal] under the tree this year, they should probablyread Sun's press release about their last [financial results].)A few others contacted me about this also, from a bunch of rather different angles, from reverse-engineering emulation of other company's chipsets to my use of internal codenames. (There are now MORE than seven words I can't type in this blog!) Jon is just trying to gather information, but his [head hurts] from all of this debate.
This week I will try to clarify some of the confusion.
It seems like [only yesterday] I was talking about IBM's strategic initiatives for the New Enterprise Data Center, including the launch of asset and service management at [Pulse 2008] in Orlando, Florida.
This week, my colleagues are at [Pulse 2009] in Las Vegas, Nevada. (I'm not there this time, so stop asking all my colleagues where I am!)Obviously, a lot has change in the last 12 months: the world's financial economy has collapsed, our delicate environment continues to unravel, and a new US President was elected to fix all that was broken by the former occupant. As a result, IBM's strategy has evolved beyond just data centers for large enterprises.
I can't think of a better time to emphasize the need for a more dynamic infrastructure. And this is not just focused on IT operations, but smarter business infrastructure as well, as the two now are very much intertwined. Everything from smarter healthcare, smarter telecom, smarter retail, smarter distribution, smarter transportation, and smarter financial services. IBM's [Dynamic Infrastructure@reg;] is one of four strategic initiatives to help build a smarter planet.
Let's take a quick look at the key benefits:
Do you remember back to the days that the IT department was like the accounting department in the back office, merely recording what happened in a series of transactions? Not anymore! Today, IT is front and center of most businesses, helping to generate revenue, drive innovation, and provide better customer service. We are finding a convergence between the physical world of running business with the digital world of IT. Intelligence is everywhere, embedded in systems and operations throughout, not just in a data center.
Imagine only 10-15 years ago the primary concern for IT operations was the cost of hardware. Now, thanks to[Moore's law], hardware is cheaper, but other IT budget costs like labor, management software, power and cooling costs are growing faster and becoming more predominant factors. IBM recognizes that you must consider thetotal cost of ownership, not just the acquisition cost of new hardware. But again, this isn't just reducing the costs of IT, but making more effective use of IT resources to reduce costs everywhere else, in schedulingtransportation, in managing manufacturing assets, and so on.
While the world feels much safer now that Barack Obama has taken over, there are still risks and threats out there, and businesses large and small have to manage them. Economic swings like we have experienced lately help weed out those companies that had fixed costs and static infrastructures, in favor of those with more variable costs and dynamic infrastructures. When the marketplace slows down, can your business "dial down" its operations to match? And when the recession is over and business is booming again, can your business "ramp up" fast enough to take on new opportunity? With IBM's Cloud Computing, companies can minimize their fixed investments and use a variable amount of computing as business needs change dynamically.
To learn more about Dynamic Infrastructure, read the IBM [Press Release].
The IBM Storage and Storage Networking Symposium continues ...
DS8300 Benchmark for Global Mirror
Phil Allison of Fidelity National Information Services presented his success switching from competition over to IBM DS8300 disk systems for use with Global Mirror. They had usedPerformance Associates famous PAIO driver to help to the benchmarktesting. They ran the benchmars at 2x and 3x their current workloads to see how well the DS8000 performed,measuring IOPS, MB/sec, and millisecond response time (msec). They were very impressed with their results,staying below their target 0.8 msec for most of their runs.
For the Global Mirror, the did a performance "bake-off" between Ciena CN2000 versus Cisco 9216i. These areimplemented differently. Ciena uses a Layer-2 approach, encapsulating the Fibre Channel packets directlyto transport as SDH/SONET or Gigabit Ethernet (GigE), which required dedicated circuits between JacksonvilleFlorida and Little Rock, Arkansas. By contrast, Cisco uses a Layer-3 approach, encapsulating Fibre Channelpackets within an IP packet, which can leverage existing datacenter-to-datacenter backbone.
To add stress to the benchmarks, they used a "Network Impairment" emulator. These artificially inject errors,lose packets, and other signal loss conditions. Running both Cisco and Ciena under these tests help them decide which to purchase, but also enforced that idea that they made the right choice choosing IBM for theirremote distance mirroring solution.
Comparison of Bare Machine Recovery Techniques
"Bare machine recovery" is the phrase used to restore a machine that has no operating system installed (or thewrong operating system). Dave Canan from IBM Advanced Technical Support did a great job reviewing the variousproducts and techniques available, and the pros and cons of each approach. The ones he covered were:
Tivoli Storage Manager - install fresh Windows Operating System, TSM client, and then follow certain steps
Automated System Recovery(ASR) - a new feature of Windows XP and Windows 2003 works with TSM client
Symantec Ghost - formerly callled PowerQuest Drive Image, there are now two versions: Ghost Home Edition and Ghost Corporate Solution Suite
Cristie Bare Machine Recovery(CBMR) - This is an IBM partner that provides both Linux and Windows PE versions. Cristie includes a license for Windows PE, so no need to use the alternative Bart PE method.
SAN Volume Controller - Customer Experience
Bill Giles of Catholic Medical Center, a hospital in New Hampshire, presented his experienceswith IBM System Storage SAN Volume Controller. They have a mix of IBM System x, System p, andSystem i servers, as well as machines from HP, Sun, and Dell. For applications, they havePicture Archiving and Communicatiion System (PACS) for cardiology and radiology, HL7 Interface engine, Clinical Information System, TSM for backup, and Microsoft Exchange fore-mail.
They deployed SVC on AIX, Solaris, Windows 2000 and 2003. They were very delightedwith the results:
Centralized Storage Provisioning
Consolidating disparate storage into a universal platform
Enables non-disruptive data migration
Increased utilization of existing disk resources
Improved disaster recovery with FlashCopy and Metro Mirror
Birds of a Feather (BOF) sessions
We had two BOFs, one for storage attached to System z operating systems, and another for storage attached to Linux, UNIX and Windows systems. This distinctionmade sense when mainframes could only attach to CKD disks and ESCON/FICON tape,and distributed systems could only do FCP/SCSI, but these days, there are all kindsof convergence going on.
Linux on System z can now attach via FCP to LTO tape and SAN Volume Controller, allowing now a wide range of storage options for that platform. z/OS, z/VM, z/VSEand Linux on System z can all access IBM System Storage N series via NFS.
The format was traditional Q&A panel, we had experts at the front of the room,handling the questions and discussion topics brought up by the audience. I'll spareyou the individual questions and answers.
IBM announced the industry's first corporate-led initiative to enable clients to earn energy efficiency certificates for reducing the energy needed to run their data centers.For the first time, this provides a way for businesses to attain a certified measurement of their energy use reduction, a key, emerging business metric. The certificates can be traded for cash on the growing energy efficiency certificate market or otherwise retained to demonstrate reductions in energy use and associated CO2 emissions. The Efficiency Certificates initiative engages Neuwing Energy Ventures, a leading verifier of energy efficiency projects and marketer of energy efficiency certificates.
How it works:
The Neuwing Energy assessments are a two-part evaluation to 1) determine the initial energy draw from the data center or IT equipment identified for consolidation based on industry accepted energy estimates for the servers in use and the power and cooling profiles of the data center, and 2) a second review of energy draw after steps are taken that are designed to reduce energy consumption.
Neuwing Energy will issue customers an Efficiency Certificate for the total megawatt-hours of energy no longer needed to power and cool their data center or operate IT equipment. Neuwing Energy will keep a portion of each customer's earned certificates or charge a per MWH saved fee in exchange for the assessment.
Customers can trade earned Efficiency Certificates on the energy efficiency certificate market or they can retain their certificates, using them to demonstrate reductions in energy use and associated CO2 emissions.
IBM intends to make the Efficiency Certificates program available across its entire line of server and storage offerings.
Continuing my week in Tokyo, Japan, I was going to title this post "Chunks, Extents and Grains", but decidedinstead to use the fairy tale above.
Fellow blogger BarryB from EMC, on his The Storage Anarchist blog, once again shows off his [PhotoShop talents], in his post [the laurel and hardy of thin provisioning]. This time, BarryB depicts fellow blogger and IBM master inventor, Barry Whyte, as Stan Laurel and fellow blogger Hu Yoshida from HDS as Oliver Hardy.
At stake is the comparison in various implementations of thin provisioning among the major storage vendors.On the "thick end", Hu presents his case for 42MB chunks on his post [When is Thin Provisioning Too Thin]. On the "thin end", IBMer BarryW presents the "fine-grained" details of Space-efficient Volumes (SEV), made available with the IBM System Storage SAN Volume Controller (SVC) v4.3, in his series of posts:
BarryB paints both implementations as "extremes" in inefficiency. Some excerpts from his post:
"... Hitachi's "chubby" provisioning is probably more performance efficient with external storage than is the SVC's "thin" approach. But it is still horribly inefficient in context of capacity utilization.
... the "thin extent" size used by Symmetrix Virtual Provisioning is both larger than the largest that SVC uses, and (significantly) smaller than what Hitachi uses."
"free" may be the most expensive solution you can buy...
Before you rush off to put a bunch of SVCs running (free) SEV in front of your storage arrays, you might want to consider the performance implications of that choice. Likewise, for Hitachi's DP, you probably want to understand the impact on capacity utilization that DP will have. DP isn't free, and it isn't very space efficient, either."
BarryB would like you to think that since EMC has chosen an "extent" size between 257KB and 41MB it must therefore be the optimal setting, not too hot, and not too cold. As I mentioned last January in my post[DoesSize Really Matter for Performance?], EMC engineers had not yet decided what that extent size should be, andBarryB is noticeably vague on the current value.According to this [VMware whitepaper],the thin extent size is currently 768 KBin size. Future versions of the EMC Enginuity operating environment may change the thin extent size. (I am sure theEMC engineers are smarter and more decisive than BarryB would lead us to believe!)
BarryB is correct that any thin provisioning implementation is not "free", even though IBM's implementation is offeredat no additional charge. Some writes may be slowed downwaiting for additional storage to be allocated to satisfy the request, and some amount of storage must be set asideto hold the metadata directory to point to all these chunks, extents or grains. For the convenience of not havingto dynamically expand LUNs manually as more space is needed, you will pay both a performance and capacity "price".
However, as they say, the [proof of the pudding is in the eating], or perhaps I should say porridge in this case.Given that the DMX4 is slower than both HDS USP-V and IBM SVC, you won't see EMC publishing industry-standard[SPC benchmarks] using their"thin extent" implementation anytime soon. IBM allows a choice of grain size, from 32KB to 256KB, in an elegantdesign that keeps the metadata directory less than 0.1 to 0.5 percent overhead. I would be surprised if EMC canmake a case to be more efficient than that! The performance tests are stillbeing run, but what I have seen so far, people will be very pleased with the minimal impact from IBM SEV, an acceptable trade-off for improved utilization and reduced out-of-space conditions.
So if you are a client waiting for your EMC equipment to be fully depreciated so you can replace it for faster equipment from IBM or HDS, you can at least improveits performance and capacity utilization today by virtualizing it with IBM SAN Volume Controller.
Did you miss your chance to attend Storage Networking World last week? IBM has some upcoming conferences that might be of interest to you.
IBM Systems Conference 2009
In this inaugural event, IBM executives, developers and industry experts reveal the latest innovations, trends and directions. In the span of three full days, you will hear and see technologies demonstrated that are needed to transform and respond effectively in these economic times.
There will be three tracks:
IBM Systems -- Including storage, mainframe, POWER and x86 systems
Solutions for a Dynamic Infrastructure
Professional Development -- including negotiation skills, project management and TCO analysis
IBM System Storage and Storage Networking Symposium
If the above conference is too broad, we have a more storage-specificconference. The [IBM System Storage and Storage Networking Symposium] brings IBM storage developers, architects, technical experts, solution providers and customer speakers together in one place to show you how to address the growing challenge of managing and securing retention managed data. You'll also learn about the latest IBM System Storage™ portfolio product announcements.
I have spoken at these perhaps 12 of the last 14 years. The list of presenters has not yet finalized, so I do not yet know if I will actually be there this year.
Two exciting things are new this year. First, instead of being in San Diego or Las Vegas, it will be held in Chicago, Illinois instead!Secondly, you get a two-for-one with the [IBM System x and BladeCenter Technical Conference]. That's right, they are co-located there in Chicago so that you can attend sessions from both! Perhaps you spend 80 percent of your time on storage, and 20 percent on x86 servers, or 80 percent servers and 20 percent storage, now you can register for one price, and decide when you get there.
If you act soon, you can save money with the early-registration discount by May 31.
Hopefully, this will give you enough time to plan and make travel arrangements!
