Continuing my coverage of the Data Center 2010 conference, Monday I attended four keynote sessions.
The first keynote speaker started out with an [English proverb]: Turbulent waters make for skillful mariners.
He covered the state of the global economy and how CIOs should address the challenge. We are on the flat end of an "L-shaped" recovery in the United States. GDP growth is expected to be only 4.7 percent Latin America, 2.3 percent in North America, 1.5 percent Europe. Top growth areas include 8.0 percent India and 8.6 percent China, with an average of 4.7 growth for the entire Asia Pacific region.
On the technical side, the top technologies that CIOs are pursuing for 2011 are Cloud Computing, Virtualization, Mobility, and Business Intelligence/Analytics. He asked the audience if the "Stack Wars" for integrated systems are hurting or helping innovation in these areas.
Move over "conflict diamonds", companies now need to worry about [conflict minerals].
He proposed an alternative approach called Fabric-Based Infrastructure. In this new model, a shared pool of servers is connected to a shared pool of storage over an any-to-any network. In this approach, IT staff spend all of their time just stocking up the vending machine, allowing end-users to get the resources they need.
Crucial Trends You Need to Watch
The second speaker covered ten trends to watch, but these were not limited to just technology trends.
Virtualization is just beginning - even though IBM has had server virtualization since 1967 and storage virtualization since 1974, the speaker felt that adoption of virtualization is still in its infancy. Ten years ago, average CPU utilization for x86 servers of was only 5-7 percent. Thanks to server virtualization like VMware and Hyper-V, companies have increased this to 25 percent, but many projects to virtualized have stalled.
Big Data is the elephant in the room - storage growth is expected to grow 800 percent over the next 5 years.
Green IT - Datacenters consume 40 to 100 times more energy than the offices they support. Six months ago, Energy Star had announced [standards for datacenters] and energy efficiency initiatives.
Unified Communications - Voice over IP (VoIP) technologies, collaboration with email and instant messages, and focus on Mobile smartphones and other devices combines many overlapping areas of communication.
Staff retention and retraining - According to US Labor statistics, the average worker will have 10 to 14 different jobs by the time they reach 38 years of age. People need to broaden their scope and not be so vertically focused on specific areas.
Social Networks and Web 2.0 - the keynote speaker feels this is happening, and companies that try to restrict usage at work are fighting an uphill battle. Better to get ready for it and adopt appropriate policies.
Legacy Migrations - companies are stuck on old technology like Microsoft Windows XP, Internet Explorer 6, and older levels of Office applications. Time is running out, but migration to later releases or alternatives like Red Hat Linux with Firefox browser are not trivial tasks.
Compute Density - Moore's Law that says compute capability will double every 18 months is still going strong. We are now getting more cores per socket, forcing applications to re-write for parallel processing, or use virtualization technologies.
Cloud Computing - every session this week will mention Cloud Computing.
Converged Fabrics - some new approaches are taking shape for datacenter design. Fabric-based infrastructure would benefit from converging SAN and LAN fabrics to allow pools of servers to communicate freely to pools of storage.
He sprinkled fun factoids about our world to keep things entertaining.
50 percent of today's 21-year-olds have produced content for the web. 70 percent of four-year-olds have used a computer. The average teenager writes 2,282 text messages on their cell phone per month.
This year, Google averaged 31 billion searches per month, compared 2.6 billion searches per month in 2007.
More video has been uploaded to YouTube in the last two months than the three major US networks (ABC, NBC, CBS) have aired since 1948.
Wikipedia averages 4300 new articles per day, and now has over 13 million articles.
This year, Facebook reached 500 million users. If it were a country, it would be ranked third. Twitter would be ranked 7th, with 69% of their growth being from people 32-50 years old.
In 1997, a GB of flash memory cost nearly $8000 to manufacture, today it is only $1.25 instead.
The computer in today's cell phone is million times cheaper, and thousand times more powerful, than a single computer installed at MIT back in 1965. In 25 years, the compute capacity of today's cell phones could fit inside a blood cell.
See [interview of Ray Kurzweil] on the Singularity for more details.
The Virtualization Scenario: 2010 to 2015
The third keynote covered virtualization. While server virtualization has helped reduce server costs, as well as power and cooling energy consumption, it has had a negative effect on other areas. Companies that have adopted server virtualization have discovered increased costs for storage, software and test/development efforts.
The result is a gap between expectations and reality. Many virtualization projects have stalled because there is a lack of long-term planning. The analysts recommend deploying virtualization in stages, tackle the first third, so called "low hanging fruit", then proceed with the next third, and then wait and evaluate results before completing the last third, most difficult applications.
Virtualization of storage and desktop clients are completely different projects than server virtualization and should be handled accordingly.
Cloud Computing: Riding the Storm Out
The fourth keynote focus on the pros and cons of Cloud Computing. First they start by defining the five key attributes of Cloud: self-service, scalable elasticity, shared pool of resources, metered and paid per use, over open standard networking technologies.
In addition to IaaS, PaaS and SaaS classifications, the keynote speaker mentioned a fourth one: Business Process as a Service (BPaaS), such as processing Payroll or printing invoices.
While the debate rages over the benefits between private and public cloud approaches, the keynote speaker brings up the opportunites for hybrid and community clouds. In fact, he felt there is a business model for a "cloud broker" that acts as the go-between companies and cloud service providers.
A poll of the audience found the top concerns inhibiting cloud adoption were security, privacy, regulatory compliance and immaturity. Some 66 percent indicated they plan to spend more on private cloud in 2011, and 20 percent plan to spend more on public cloud options. He suggested six focus areas:
Test and Development
Prototyping / Proof-of-Concept efforts
Web Application serving
SaaS like email and business analytics
Select workloads that lend themselves to parallelization
The session wrapped up with some stunning results reported by companies. Server provisioning accomplished in 3-5 minutes instead of 7-12 weeks. Reduced cost of email by 70 percent. Four-hour batch jobs now completed in 20 minutes. 50 percent increase in compute capacity with flat IT budget. With these kind of results, the speaker suggests that CIOs should at least start experimenting with cloud technologies and start to profile their workloads and IT services to develop a strategy.
That was just Monday morning, this is going to be an interesting week!
Continuing my coverage of the Data Center 2010 conference, Monday I afternoon included presentations from IBM executives.
Blueprint for a Smart data center
Steve Sams, IBM Vice President, Global Site and Facilities Services, is well known at this conference. In charge of designing and building data center facilities for IBM and its clients, he has lots of experience in various datacenter configurations.
The presentation was an update from last year's [Data Center Cost Saving Actions Your CFO Will Love]. 70 cents of every IT dollar is spent on just keeping the existing systems running, leaving only 30 percent to handle growth and business transformation. Over 70 percent of datacenters are more than seven years old, and may not be designed to handle today's density in IT equipment.
Many companies wanting to virtualize are stalled. IBM's Server Virtualization Analytics services can help cut this transformation time in half, with an ROI of only 6-18 months for complex Wintel environments. This is just one of the 17 end-to-end datacenter analytics tools IBM offers. The results have been 220 percent more VM instances per admin FTE than traditional deployments. IBM drinks its own champagne, having saved over $4 Billion USD in its own datacenter consolidation and virtualization projects.
Want to Cut the Cost of Storage in Half? Here’s How
The speaker of this session started out with a startling prediction: the amount of storage purchased in the five years 2010-2014 will be 25x what was purchased in 2009, on a PB basis. Most attempts to stem this capacity growth have failed. Therefore, the focus to cut storage costs need to be elsewhere.
The first concern is poor utilization. Utilization on DAS averages 10 percent, SANs 40-50 percent. Thin provisioning can raise this to 60-75 percent. Thin Provisioning was first introduced for the mainframe storage in the 1990s by StorageTek which IBM resold as the IBM RAMAC Virtual Array (RVA), but many credit 3PAR for porting this over to distributed operating systems in 2002. Other options include data deduplication and compression to reduce the cost of storing data on disk.
The second approach is use of storage tiering. In this case, the speaker felt SATA was 3x cheaper ($/GB) but can also be 3x lower performance. Moving data between faster FC/SAS 10K and 15K RPM drives to slower 7200 RPM drives can offer some cost reductions.
Implementing "quotas" in email, file systems or other applications is one of the worst financial decisions an IT department can make, as it merely shifts the storage management from experts (IT staff) to non-experts (end users).
The speaker recommended using archive instead. Keeping backup tapes for long-term is not archive, backups should not be older than eight weeks old.
Interactive polls of the audience gave some interesting insight:
When asked expected storage capacity "compound annual growth rate" (CAGR) for the next few years, 26 percent estimate 35-50 CAGR, 30 percent estimate 50-75 CAGR, and 15 estimate greater than 75 percent CAGR.
For thin provisioning, 43 percent of the audience already are using it, and 33 percent plan to next year.
Similarly , 41 percent of audience is using data deduplication for their primary data, and 30 percent plan to next year.
For automated tiering that moves portions of data automatically between fast and slow tiers of storage to optimize performance, like IBM's Easy Tier, 20 percent are already using it, and 44 percent plan to next year.
41 percent already have some archiving for file systems, 17 percent plan to next year.
Only 6 percent have an all-disk backup/replication environment, but 20 percent plan to adopt this next year.
The downsize of trying to squeeze out costs with these approaches and technologies is that there can be negative impact to performance. The speaker suggested a balanced approach of adding lower cost storage to existing fast storage to meet both capacity and performance requirements.
Smarter Infrastructures Deliver Better Economics
Elaine Lennox, IBM Vice President and Business Line Executive for System Software, presented the "3 D's" of a Smarter Infrastructure: design, data and delivery.
Design: new technologies and approaches are forcing people to reconsider the design of their applications, their infrastructure and their facilities.
Data: on average, companies store 17 copies of the same piece of production data. Data needs to be managed better in the future.
Delivery: new types of cloud computing are changing the way IT services can be delivered, and how they are consumed by end users.
Roadmap to Enterprise Cloud Computing
This was a combo vendor/customer presentation. Rex Wang from Oracle presented an overview of Oracle's service and product offerings, and then Jonathan Levine, COO of LinkShare, presented his experiences deploying Oracle ExaData.
Rex presented Oracle's "Cloud maturity model" that has its customers go through the following steps:
Silo: each application on its own stack of software, server and storage.
Grid: virtualization for shared infrastructure and platforms (internal IaaS and PaaS).
Private cloud: self-service, policy-based management, metered chargeback and capacity planning.
Hybrid Cloud: workloads portable between private and public clouds, offering federation, cloud bursting, and interoperability.
Rex felt the standard "Buy vs Rent" argument in the business world applies to IT as well, and that there could be break-even points over long-term TCO analysis that favors one over the other. He cited internal research that showed 28 percent of Oracle customers have internal or private cloud, and 14 percent use public cloud. 25 percent use Application PaaS, 21 percent database PaaS, 5 percent Identity management PaaS, 10 percent Compute IaaS, 18 percent storage IaaS, and 15 percent Test/Dev IaaS.
Rex felt that in all the hype around taking a single host and dividing it into multiple VMs, people have forgotten that the opposite approach of taking multiple instances into clusters is also important. He also felt you have to look at the entire "Application Lifecycle" that goes from:
IT sets up the equipment as an internal PaaS or IaaS
Developers write the application
End users are trained and use the application
Application owners manage and monitor the application
IT meters the usage and does chargeback to each application owner
Oracle's ExaData and ExaLogic compete directly against IBM's Smart Analytics System, IBM CloudBurst, and IBM Smart Business Storage Cloud.
Next up was Jonathan Levine, COO of [LinkShare], a subsidiary of Rakutan in Japan. This is an [Affiliated Marketing] company. Instead of pay-per-view or pay-per-click web advertising, this company only gets paid when the "end user" actually buys something when clicking on web advertising.
The business runs on an 8TB data warehouse and 1 TB OLTP database, ingesting 50GB daily, with 400 million transactions per day with 8.5 GB/sec throughput.
They discovered that the Oracle ExaData did not work right out of the box. In fact, it took them about a year to get it working for them, roughly the same amount of months it took them on their last Oracle 10 to Oracle 11 conversion.
Part of their business allows advertisers and web content publishers to generate reports on activity. Jonathan indicates that if the response is longer than 5 seconds, it might as well be an hour. He called this the "Excel" rule, that results need to be as fast as local PC Microsoft Excel pivot table processing.
With the new Exadata, they met this requirement. Over 84 percent of their transactions happen under 2 seconds, 9 percent take 2-4 seconds, and another 4 percent in the 4-8 second range. They hope that as they approach the winter holiday season that they can handle 2-3x more traffic without negatively impacting this response time.
This week I am blogging from beautiful Caesars Palace hotel in Las Vegas, Nevada to report on what I see and hear at the
28th annual Data Center Conference. Today was simply registration, which opened at 4pm, and I was able to get my conference backpack, badge, and details of the week.
Already, I can tell there will be more people here, and it looks like the economy is on the rebound versus last year. Here are my
posts from 12 months ago when I attended this conference in 2008:
This year, we will have the IBM Portable Modular Data Center (PMDC) with XIV and iDataPlex inside, as well as several subject matter experts joining me at the solution center. Look for us in the "Hunter Green" shirts.
This week I am in beautiful Las Vegas for the Data Center 2010 Conference. While the conference officially starts Monday, I arrived on Sunday to help set up the IBM Booth (Booth "Z").
(Note: This is my third year attending this conference. IBM is a platinum sponsor for this event. The analyst company that runs this event has kindly asked me not to mention their name on this blog, display any of their logos, mention the names of any of their employees, include photos of any of their analysts, include slides from their presentations, or quote verbatim any of their speech at this conference. This is all done to protect and respect their intellectual property that their members pay for. This is all documented in a lengthy document in case I forget. So, if the picture of the conference backpack appears lopped off at the top, this was done intentionally to comply with their request. The list of sponsors at this event represents a "who's who" of the IT industry.)
The pre-conference orientation is for people who are first-timers, or for those who have not attended this conference in a while. The conference includes 7 keynote presentations and 68 sessions organized into seven "tracks" plus one "virtual track" which crosses the other seven:
Servers and Operating Systems
Cost Optimization "Virtual Track"
Each session is further classified as foundational versus advanced, business versus technical, and practical versus strategic.
The speaker also presented some unique methodologies that will be used this week, including "Magic Quadrant", "MarketScope", "Hype Cycle" and "IT Market Clock" which provide graphical representation to help attendees better understand the conference materials.
The Welcome Reception was sponsored by VCE, formerly known as Acadia, the coalition comprised of VMware, Intel, Cisco and EMC. I joked that this should be "VICE" so that Intel does not feel left out.
While we enjoyed drinks and snacks, we listened to live music from the all-violin band [Phat Strad].
The CEO of VCE, Michael Capellas, recognized me from across the room and came over to ask me how IBM was doing. We had a nice friendly chat about the IT industry and the economy.
My IBM colleague Marissa Benekos brought her hand-held video camera to [Storage Networking World] conference in Orlando, Florida.I am not there, as I had a conflict with another conference going on here in Tucson, so am relyingon Marissa to feed me information to blog about.
In this segment, she interviews "booth babe" David Bricker. I've known David a long time,and if you are there at the conference, tell him I sent you to visit him at the IBM booth.
David Bricker shows off some of the IBM System Storage product line at SNWin this YouTube video (2 minutes)
Sadly, I can't be in two places at once. SNW is a great conference to attend!
Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that many people make for their own personal lives: staying on a budget.
Often, when faced with a tightening budgets, we try to make more use of what we already have. Tell someone they are only using 10 percent of their brain, and they immediatelybelieve you; but tell them they are only using 30 percent of their storage, and they ask for a whitepaper,magazine article, or clarification on how that percentage is calculated. I actually visiteda customer that was only using6 percent of the storage attached to their Windows servers!
So, to help those of you making data center resolutions to stay on budget, the terms to remember are "Reduce", "Reuse" and "Recycle".
When people come to request storage, are they being reasonable about what they need today, or are they asking for what they might need over the next three years? They might need 50GB, but they ask for 100GB, in case they grow, and a year later, you find they have only 15GB of data on it. On the flipside, the person asks for what they need but some storage admins give out more, just so they don't have to be bothered so often when growth happens. Finally, I have seen this formalized into fixed size LUNs, all the disk is carved into big huge 100GB pieces, so if you need 20GB, here's one big enough with plenty of room to grow.
If you are going to keep on a budget, remember that storage today is 30% more expensive than storage next year. That is the average drop in both disk and tape on a dollar-per-MB basis. If there is any way to postpone giving out storage until it is actually needed, you can save a bundle of money. Timing is everything! In the event of a disaster, getting immediate replacement for disk can be very expensive, but if you can wait just two weeks, you can negotiate a better deal. I thought of this while going to the movie theatre yesterday. A "hot dog" and a bottle of water was $8.00, but if you are able to wait two hours and eat after the movie, you can get a much better meal for less.
A lot of companies buy new storage because their existing storage isn't fast enough, or doesn't have the latest copy services. This can easily be solved with an IBM SAN Volume Controller (SVC). The SVC can virtualize slower, functionless storage, and present to your application hosts virtual disks that are faster, and with all the latest disk-to-disk copy services like FlashCopy, Metro Mirror, and Global Mirror.
Chances are, you have unused disk capacity spread across all your storage today, but perhaps they are formatted into small LUNs. The SVC can combine the capacity, and let you carve up big LUNs at the sizes you need.This is like taking all those tiny pieces of soap in your shower and forming a new bar of soap, or taking all the crumbs at the bottom of your bread box, and making a new slice of bread. And, the virtual LUNs are dynamically expandable,so give out only the amount they need today, as it is simple to expand them to larger sizes later.
Of my 13 patents, the first will always be my favorite, on a function called "RECYCLE" for the Data Facility Storage Management Subsystem Hierarchical Storage Manager (DFSMShsm) product, which is now a component of the IBM z/OS operating system. Basically, tapes could contain hundreds or thousands of files, such as backup versions or archive copies, and these expired on different dates. As a result, a tape would be written100 percent full, and then over time, decrease in valid data to 80, 60, 40, 20 until it hit 0 percent. In some cases, a single filecould hold an entire tape hostage. RECYCLE was able to read the valid data off tapes that were perhaps less than 20 percent full, and consolidate them onto fewer tapes. As a result, a whole bunch of tapes could be returned to the scratch pool, and reused immediately for other workloads. This also helps in moving to newer, higher capacity cartridges, such as the new 700GB cartridge that IBM co-developed with FujiFilm.(This RECYCLE function exists in our IBM Tivoli Storage Manager software, as well as our Virtual Tape Server, but is called "reclamation" instead, to avoid confusion on searches.)
When evaluating your use of tape, determine if you are making best use of the tapes you have now, and perhaps a RECYCLE (or reclamation) scheme may be in order. Fewer tapes can save money in many ways, such as reduced storage costs, and reduced courier costs to send the tapes offsite. Tape media can still be 10-20 times less expensive than disk, based on full capacity.
Wrapping up this week's theme of New Year's Resolutions for the data center, the New York Times argues we should go easy on the resolutions, so I'll conclude with reducing stress. Lighten up! Relax, and try not to take your job so seriously.
(I know you're probably thinking, "That's easy for you to say, Mr. paid-to-play-golf-with-clients big-shot executive, but what about the rest of us?" or perhaps "I can't do that! My job is so important that if I didn't take it so seriously, my company would go bankrupt, my industry would falter, and global economies will collapse!" I can understand. Over 70 percent of all of the world's business transactions travels through, or sits on, IBM equipment, so you can imagine how stressful my past 20 years have been. Bear with me, read on, and hopefully you might benefit from my past experiences.)
Laugh out loud
Everytime someone laughs out loud at the office here in Tucson, everyone else within earshot stops what they are doing and rushes over to see what is so funny. Likewise, everytime it rains during normal working hours, people stop what they are doing, and run to the windows to see what water coming out of the sky looks like. Do you work in a "dry" climate, where laughter, like rain, is a rare occurrence?
Recognizing the benefits of laughter on reducing stress and improving health, my friends and I started theTucson Laughter Club back in 2004. There are hundreds of laughter clubs across the United States and the rest of the world, sometimes referred to as "Laughter Yoga" groups. Those of you readers in Tucson are welcome to join us, our next meeting is January 13.
Look to see if there is one near you, or start your own. Until then, laugh while you watch this funny storage-related video from the folks over at Sun StorageTek, or this one from Kodak.
Every laughter club meeting starts out with some breathing exercises. If you feel stressed, try this simple2-minute relaxation technique.
I'm not just talking about stretching our muscles here.
The next time you tell the story, stretch the truth a little, aim for 70 percent truth, 30 percent embellishment.
The next time you are making plans for lunch or dinner, stretch yourself out of your comfort zone and try something new and different, new restaurant, or different type of cuisine.
The next time you get called by a phone solicitor or telemarket, stretch out the conversation, have fun with it, ask them what they are wearing, and share with them all the successes and problems you have at work, until THEY hang up first.
The next time you are throwing a party, stretch your invite list to include someone you normally wouldn't invite, perhaps a neighbor or co-worker.
The next time someone insists you make a list,stretch the process out, to give you more time to drink their expensive wine.
Peace on earth starts one relationship at a time.I found this amusing article on Wired, discussion the Top Blogfights of 2006.Can't we all get along? I stopped two blog-fights in 2006, just by pointing to the facts, and setting the record straight.
If there is someone you are not getting along with at work, fix it. Sooner, rather than later. Here are tips to be more assertive.
Listen to Music
Can you listen to music where you work? Listening to music has been shownto help reduce stress.I've got my Thinkpad T60 laptop connected to my wireless bluetooth headset, so I can listen to relaxing music without disturbing anyone else, and not be "tethered" to my system with traditional headphone wires.
In her book, "Life Hacker: 88 tech tricks to turbocharge your day", Gina Trapani suggestsPink noise. I prefer"The Quiet Earth", an internet radio station on Live365.
So, relax and enjoy your weekend. And remember, when you get back to the office on Monday, its only ones and zeros.
Continuing this week's theme of New Year's Resolutions for the data center, today we'll talk about one that people don't always think about on a personal level, that is to hone your tools and skills.
A long time ago, I used to be a regular speaker at the SHARE user group conference. One of the most attended sessions was Sam Golob presenting the latest CBT Tape set of tools. Over time, this large collection of "mainframe shareware" was handed out on 3480 tape cartridges, then on CDs, and finally made downloadable off the web.Sam's main point, which I remember to this day, was that everyone who has a job should figure out what tools they use, keep those tools functioning properly, and learn to use them well.
Later, I took some cooking classes at a culinary school. Among other things, we learned:
A sharp knife is safer and easier to use than a dull one, resulting in fewer accidents
Knowing what you are doing is the difference between food that is "simply awful" to that which is "awfully simple" to prepare.
A well trained chef can prepare most meals with just a sharp knife and wooden spoon.
The same could be said about software tools. What tools do you use in your job? Do you feel you know how to take full advantage of their power and capabilities?If you develop software, do you know all the features for your debugging tools? If you develop advertising or marketing materials, do you know all the features of your photo or video editing software? If you manage storage in a data center, do you know all the tools for managing your storage area network (SAN), disk systems, tape libraries, and reporting tools to identify all of your files and databases across your entire IT environment?I would not be surprised if you could replace a whole mess of tools with just one, such as the IBM TotalStorage Productivity Center.
This year I resolve to be more consistent in my blogging, and my goal is to give you one to five entries per week, every week, based on the advice from Glenn Wolsey, Jennette Banks, and others.On some weeks, I will have a running theme, so rather than super-long entries to cover everything I can think of on a topic, make the entries short and readable. This week is a good time to review last year's "New Year's Resolutions" and to make new ones for 2007. I will discuss actions that companies can adopt for their data centers.
A common resolution is to lose weight, as in this Dilbert comic. Last year, I resolved to lose weight in 2006, and am delighted with myself that I lost eight pounds. When people ask for the secret of my success, I whisper in their ear "Eat less, exercise more." In general, people (and companies) know what to do, but just don't do it, which Pfeffer and Sutton document in their book The Knowing-Doing Gap. In my case, it involved lifestyle change: I exercised at a gym three times per week in Tucson, with a personal trainer, and revamped my diet.
Not everyone subscribes to the "eat less exercise more" philosophy. For example, Ric Watson argues in his blog that you can eat fewer calories, but eat more in actual volume, by choosing the right foods. This brings up the issues of "metrics" that most data centers are familiar with. Last year, I read the book "You: On a Diet" which explains that it is better to focus on "waist reduction" as measured in inches around your mid-section at the belly button, than "weight reduction" as measured in pounds. This year, I resolve to get down to 35 inches by the end of 2007.
The problem with measuring "weight" is that you are weighing bones, muscle and fat. A person can gain ten pounds of muscle, lose ten pounds of fat, and the scale would indicate no progress. The same problem occurs in data centers. How many TB of data do you have? Storage admins can easily tell you, but can they tell how much of this is bone (data needed for operating infrastructure), muscle (data used in daily operations that generates revenue) or fat (obsolete or orphaned data)?
We at IBM often state that "Information Lifecycle Management (ILM)" is more lifestyle change than a "fad diet". Figuring out what data you should capture in the first place, where to place it, when to move it, and when to get rid of it, is more important that just buying different tiers of storage hardware. So, for those looking to make new data center resolutions, I suggest the following actions:
Re-evaluate the metrics you now use, and determine if they are helpful in making decisions and taking action.
Come up with new ones that are more focused to solve the issues you face.
Consider storage infrastructure software, such as IBM TotalStorage Productivity Center, to help you gather the information about your SAN, disk and tape systems, calculate the metrics, and automate the appropriate actions.
Well, I'm back from my vacation from Bali and Singapore, and am glad to seethat my fellow blogger BarryB [aka Storage Anarchist] also had a chance to take a break to exotic locations.
Next Thursday, in the USA, is [Thanksgiving holiday], so this will give me a chance to catch up on my email and read everyone's blog posts and product announcements.
The following week, December 2-5, I'll be attending the 27th annual [Data Center Conference] at the MGM Grand hotel and casino in Las Vegas, Nevada. IBM is a Premier and Platinum sponsor for this event.Look for me in one of the many break-out sessions, one-on-oneexecutive meetings, or IBM's "booth 20" at the solution center. Our team will be showingoff IBM's XIV, SVC and TotalStorage Productivity Center offerings, aswell as explaining IBM Information Infrastructure and the rest of theNew Enterprise Data Center strategy.
I had attended this conference the past four years, but sadly will not be attending the one this year. If you are attending this conference for the first time, perhaps a quick look at my blog posts from last year will help you get oriented:
For those in the US, last friday, the day after Thanksgiving, marks the official start of the Holiday shopping season. This has been called [Black Friday] as some stores open as early as 4am in the morning, when it is still dark outside, to offer special discount prices. Some shoppers camp out in sleeping bags and lawn chairs in front of stores overnight to be the first to get in.
Not surprisingly, some folks don't care for this approach to shopping, and prefer instead shopping online. Since 2005, the Monday after Thanksgiving (yesterday) has been called [Cyber Monday].USA Today newspaper reports [Cyber Monday really clicks with customers]. Many of the major online shopping websites indicated a 37 percent increase in sales yesterday over last year's Cyber Monday.
On Deadline dispels the hype on both counts:[Cyber Monday: Don't Believe the Hype?"], indicating that Black Friday is not the peak shopping for bricks-and-mortar shops, andthat Cyber Monday is not the busiest online shopping day of the year, either.
A flood of new video and other Web content could overwhelm the Internet by 2010 unless backbone providers invest up to US$137 billion in new capacity, more than double what service providers plan to invest, according to the study, by Nemertes Research Group, an independent analysis firm. In North America alone, backbone investments of $42 billion to $55 billion will be needed in the next three to five years to keep up with demand, Nemertes said.
Internet users will create 161 exabytes of new data this year, and this exaflood is a positive development for Internet users and businesses, IIA says.
If the "161 Exabytes" figure sounds familiar, it is probably from the IDC Whitepaper [The Expanding Digital Universe] that estimated the 161 Exabytes created, captured or replicated in 2006 will increase six-fold to 988 Exabytes by the year 2010. This is not just video captured for YouTube by internet users, but also corporate data captured by employees, and all of the many replicated copies. The IDC whitepaper was based on an earlier University of California Berkeley's often-cited 2003[How Much Info?] study, which not only looked at magnetic storage (disk and tape), but also optical, film, print, and transmissions over the air like TV and Radio.
A key difference was that while UC Berkeley focused on newly created information, the IDC study focused on digitized versions of this information, and included theadded impact of replication.It is not unusual for a large corporate databases to be replicated many times over. This is done for business continuity, disaster recovery, decision support systems, data mining, application testing, and IT administrator training. Companies often also make two or three copies of backups or archives on tape or optical media, to storethem in separate locations.
Likewise, it should be no surprise that internet companies maintain multiple copies of data to improve performance.How fast a search engine can deliver a list of matches can be a competitive advantage. Content providers may offer the same information translated into several languages.Many people replicate their personal and corporate email onto their local hard drives, to improve access performance, as well as to work offline.
The big question is whether we can assume that an increased amount of information created, captured and replicated will have a direct linear relation to the growth of what is transmitted over the internet. Three fourths of the U.S. internet users watched an average of 158 minutes of online video in May 2007, is this also expected to grow six-fold by 2010? That would be fifteen hours a month, at current video densities, or more likely it would be the same 158 minutes but of much higher quality video.
On the other hand, much of what is transmitted is never stored, or stored for only very short periods of time.Some of these transmissions are live broadcasts, you are either their to watch and listen to them when they happen, or you are not. Online video games are a good example. The internet can be used to allow multiple players to participate in real time, but much of this is never stored long-term. An interesting feature of the Xbox 360 is to allow you to replay "highlight" videos of the game just played, but I do not know if these can be stored away or transferred to longer term storage.
Of course, there will always be people who will save whatever they can get their hands on. Wired Magazine has anarticle [Downloading Is a Packrat's Dream], explaining that many [traditional packrats] are now also "digital packrats", and this might account for some of this growth. If you think you might be a digital packrat,Zen Habits offers a [3-step Cure].
In any case, the trends for both increased storage demand, and increased transmission bandwidth requirements, are definitely being felt. Hopefully, the infrastructure required will be there when needed.
This week, SHARE conference is being held at the Colorado Convention Center in Denver, Colorado. I covered this conference for 10 years earlier in my career. Now, my colleague Curtis Neal covers these on a regular basis, and is giving the following presentations this week:
IBM Virtual Tape Products: DILIGENT ProtecTIER and TS7700 Update
Wednesday (1:30-2:30pm), Curtis will present IBM's premier virtual tape libraries. The TS7650G ProtecTIER Data Deduplication solution supports distributed systems like Windows, UNIX and Windows. The TS7700 supports the IBM System z mainframe.
SAN Volume Controller Update
Thursday (8:00-9:00am), Curtis will cover the latest features of the IBM System Storage SAN Volume Controller (SVC). SVC has features like thin provisioning, vDisk mirroring, and cascaded FlashCopy support.
IBM System Storage DS5000 Update
Friday (8:00-9:00am), Curtis will cover the DS5100 and DS5300, and probably the new DS5020 model. These are midrange disk systems that provide excellent performance for distributed systems, full disk encryption, and intermix of FC and SATA drives.
Unlike other conferences where people just go once and are never seen again, SHARE brings back the same people back year after year, so that you can maintain relationships across organizations, and can carry on forward-looking strategic discussions.
HDP brings the performance benefits of automated wide striping and HDT automatically keeps the hot pages of data on the highest performance tier of storage for mainframes, just as it does for open systems. There are differences between open systems and mainframe implementation due to mainframe CKD and CCHHR formats for instance, the page size is optimized for mainframe storage formats and storage reclamation must be host initiate. For more information check out our website: http://www.hds.com/assets/pdf/how-to-apply-latest-advances-in-hitachi-mainframe-storage.pdf
There are also additional performance efficiencies specific for mainframes.
Mainframe HDP is the foundation for Extended Addressable Volumes, which increases the size of 3390 volumes from 65,520 cylinders to 262,668 cylinders. This, along with HyperPAV--which facilitates multiple accesses to a volume, addressing the problem of queuing on a very large volume with a single UCB--enhances throughput with many more concurrent I/O operations.
The thin provisioning of HDP also increases the performance of mainframe functions that move, copy, or replicate these thin volumes like Concurrent Copy, FlashCopy V02, and HUR, since the actual volumes are smaller.
If you have mainframes, check out the capacity and performance efficiency of VSP with HDP and HDT.
At this point, you might be wondering: "If Hu Yoshida deleted his blog post, how did Tony get a copy of it? Did Tony save a copy of the HTML source before Hu deleted it?" No. I should have, in retrospect, in case lawyers got involved. It turns out that deleting a blog post does not clear the various copies in various RSS Feed Reader caches. I was able to dig out the previous version from the vast Google repository. (Many thanks to my friends at Google!!!).
(Lesson to all bloggers: If you write a blog post, and later decide to remove it for whatever legal, ethical, moral reasons, it is better to edit the post to remove offending content, and add a comment that the post was edited, and why. Shrinking a 700-word article down to 'Sorry Folks - I decided to remove this blog post because...' would do the trick. This new edited version will then slowly propagate across to all of the RSS Feed Reader caches, eliminating most traces to the original. Of course, the original may have been saved by any number of your readers, but at least if you have an edited version, it can serve as the official or canonical version.)
Perhaps there was a reason why HDS did not want to make public the FUD its sales team use in private meetings with IBM mainframe clients. Whatever it was, this appears to be another case where the cover-up is worse than the original crime!
I am in Toronto, Canada. It is a lot cold and rainy here, worse than last week in Seoul, Korea.This looks like a slow news week, so slow that the only news here in Canada is the possibility of anew 5-dollar coin. I thought I would make this week's theme about enterprise applications.
IBM doesn't make these applications anymore, we have decided to focus on our core strength, to be the best IT platform to run other people's applications. This means being the best IT systems, software and services company. However, many of the companies that make enterprise applications are both cooperate and compete against parts of IBM, what we call "coopetition".
Let's take a look at some acronyms in this space:
"Enterprise Resource Planning" represents all the basic applications that business need to run theirbusiness, including: finance, accounting, human resources, and manufacturing. The focus here is to streamline operations and make the workforce more productive. Before IBM, I ran my ownsoftware development company, Pearson Kurath Systems, and we developed ERP applications for clients oneby one, customized to their industry requirements.
"Customer Relationship Management" or sometimes "Client Relationship Management" help companies identifyand retain their customer base. Focus here is to increase customer satisfaction and loyalty.
"Supply Chain Management" help track supply and just-in-time inventory demand, sharing the information withkey suppliers and distributors. The focus is to manage inventories down to nothing, and improve speed to get products out to market.
"Business to Business" refer to procurement, purchase orders, and collecting payments over the internet.One of my pet peeves are acronyms that use "2" to mean "to" and "4" to mean "for".
"Human Capital Management" deals with managing costs of Human Resources (HR) and coordinating servicesfrom outside organizations.
"Knowledge Management" refers to sharing and collaborating information. This is not just email and instant messaging, but also online calendaring, experience repositories, client case studies, and anecdotes.
This week I will cover applications that address these, and how they relate to storage.
Wrapping up my week in China, I read an article by Li Xing in the local "China Daily" about energy efficiency in buildings. She argues that it is not enough for a building to be energy-efficient on its own, but you have to consider the impact of the other buildings around. Does it reflect the sun so harshly into neighboring windows that people are forced to put up blinds and use artificial light? Does it block the sun, so that rooms that previously could be used with natural sunlight must now be artificially lit?
A similar effect happens with power and cooling in the data center. Servers and storage systems generate heat, and that heat affects all the other equipment in the data center. IBM has the most power-efficient and heat-efficient servers and storage, but that is not enough. You have to consider the heat generated by all systems that might raise overall temperature.
Research has indicated that water can remove far more heat per volume unit than air. For example, in order to disperse 1,000 watts, with 10 degree temperature difference, only 24 gallons of water per hour is needed, while the same space would require nearly 11,475 cubic feet of air. IBM's Rear Door Heat eXchanger helps keep growing datacenters at safe temperatures, without adding AC units. The unobtrusive solution brings more cooling capacity to areas where heat is the greatest -- around racks of servers with more powerful and multiple processors.
The CoolBlue portfolio of IBM innovations includes comprehensive hardware and systems-management tools for computing environments, enabling clients to better optimize the power consumption, management and cooling of infrastructure at the system, rack and datacenter levels. The CoolBlue portfolio includes IBM PowerConfigurator, PowerExecutive, and Rear Door Heat eXchanger.
The eXchanger works on standard 42U racks, and can help clients deal with the rapid growth of rack-mounted servers and storage on their raised floor. How cool is that!
Continuing my week in Auckland, New Zealand, I presented my last three topics for the week.
Selling IBM System Storage against competition - Part 1. You would think that since IBM's storage products are, in general, easier to use, faster, at a lower cost of ownership than the offerings from our competitors, there would not need to be a presentation like this. Since there are so many reasons why IBM is better, I split the session into two parts.
Selling IBM System Storage against competition - Part 2. With so much material, I needed to provide some structure. In the past, some Top Gun instructors organized by category, Enterprise Class, Midrange, and Entry level. I chose, instead, to organize by the different competitors themselves.
Selling IBM PureSystems. IBM PureSystems feature the Storwize V7000 and Flex System V7000 disk systems inside, and support all of IBM's disk and tape offerings outside the frame. I covered Flex Systems, PureFlex, PureApplication and PureData, including the newly announced PureData System for Hadoop.
We often joke that I.B.M. stands for "Information Between Meals"! Here we are at a restaurant in the [Britomart] area. I am on [the Paleo diet], which is low-carb, high-protein, dairy-free and gluten-free, and am trying to stick with it even when on the road traveling. Sometimes it can be challenging. Tonight, I opted for a light dinner, just roasted vegetables and grape-flavored beverage.
The folks in New Zealand love sheep. There are nine sheep for every person in this country. Here are some metal sculpture lawn ornaments.
Hyein and I needed new "desktop wallpaper" photos for our laptops. For those who want to dress up their laptops, here's one for each of us. (Click on each photo to see full size). Hyein kept getting her hair in the way. I didn't have that problem, but was worried my cap would fly off my head. This cap was a gift from my clients at [James Cook University in Brisbane, Australia].
In Top Gun classes, the top students are given "Top Gun" caps and their picture is published on the official website for all to see their success. Overall, the entire class did very well, and these three outstanding students had the top scores.
I am now in Sydney, Australia -- to teach Top Gun class again!
The BP oil spill in the Gulf of Mexico is a good reminder that all organizations should consider practice and execution of their contingency plans. In this most recent case, the [Deepwater Horizon] oil platform had an explosion on April 20, resulting in oil spewing out at an estimated 19,000 barrels per day. While some bloggers have argued that BP failed to plan, and therefore planned to fail, I found that hard to believe. How can a billion-dollar multinational company not have contingency plans?
The truth is, BP did have plans. Karen Dalton Beninato of New Orleans' City Voices discusses BP's Gulf of Mexico Regional Oil Spill Response Plan (OSRP) in her article [BP's Spill Plan: What they knew and when they knew it]. A
[redacted 90-page version of the OSRP] is available on their website.
The plan indicates that it may be 30 days from the time a deep offshore leak reaches the shoreline, giving OSRP participants plenty of time to take action.
(Having former politicians [blame environmentalists] for this crisis does not help much either. At least the deep shore rigs give you 30 days to react to a leak before the oil gets to the shoreline. Having oil rigs closer to shore will just shorten this time to react. Allowing onshore oil rigs does not mean oil companies would discontinue their deep offshore operations. There are thousands of oil rigs in the Gulf of Mexico. Extracting oil in the beautiful Alaska National Wildlife Reserve [ANWR] might be safer, it does not eliminate the threat entirely, and any leak there would be damaging to the local plant and animals in the same manner.)
So perhaps the current crisis was not the result of a lack of planning, but inadequate practice and execution. The same is true for IT Business Continuity / Disaster Recovery (BC/DR) plans. In all cases, there are four critical parts:
The planning team needs to anticipate every possible incident, determine the risks involved and the likelihood of impact, and either accept them, or decide to mitigate them. This can include natural disasters (hurricanes, fires, floods) and technical issues (computer viruses, power outages, network disruption).
Mitigation can involve taking backups, having replicated copies at a remote location, creating bootable media, training all of the appropriate employees, and having written documented procedures. IBM's Unified Recovery Management approach can protect your entire IT operations, from laptops of mobile employees, to remote office/branch office (ROBO) locations, to regional and central data centers.
When was the last time you practiced your Business Continuity / Disaster Recovery plan? I have seen this done at a variety of levels. At the lowest level, it is all done on paper, in a conference room, with all participants talking through their respective actions. These are often called "walk-throughs". At the highest level, you turn off power to your data center --on a holiday weekend to minimize impact to operating revenues-- and have the team bring up applications at the alternate site.
As many as 80 percent of these BC/DR exercises are considered failures, in that if a real disaster would have occurred, the participants are convinced they would not have achieved their target goals of Recovery Time Objective (RTO). However, they are not complete failures if they can help improve the plans, help identify new incidents that were not previously considered, and help train the participants in recovery procedures.
The last part is execution. In my career, I have been onsite for many Disaster Recovery exercises as well as after real disasters have occured. I am not surprised how many people assume that if they have plans in place, have made preparations, and have one to three practice drills per year, that the actual "execution" would directly follow. While the book [Execution] by Bossidy and Charan is not focused on IT BC/DR plans per se, it is a great read on how to manage the actual execution of any kind of business plan. I have read this book and recommend it.
If you have not tested out your IT department's BC/DR plans. Perhaps its time to dust off your copy, review it, and schedule some time for practice.
ESG Analyst, Tony Asaro, talks about the many small storage startups having aBillion Dollar Impact on the storage system industry. Tony has counted over50 storage system vendors that are now in the marketplace. Is it really that many?Most of the time, the media only focus on the top seven major players, but I agree that big players like IBM should take trends about small startups like this seriously.
EMC Blogger Chuck Hollis suggests that this trend might be the start of a squeeze play, where top players and new upstarts squeeze out the middle playerslike Sun and HDS, in his postDesperate Times In Storage Land?
(His statement that IDC and Gartner have listed EMC as number one in "almost all"market segments is perhaps a bit misleading. IBM is number one in overall storage hardware, as wellas leading in tape drives, tape libraries, tape virtualization, and for that matter,disk virtualization. I don't know if IDC or Gartner count EMC Disk Library in the "tape virtualization" category, or if either analyst distinguishes between "cache-based" versus "switch-based" disk virtualization as separate categories.Perhaps Chuck should have qualified this to say "almost all of themarket segments that EMC does business in," which of course is better than the othervendors in the middle.)
The results are finally in. IBMer Wolfgang Singer was awarded "Top Speaker" award for his NAS and iSCSI tutorial at last year's Orlando 2006 conference. Here he is receiving the awardfrom SNIA Executive Director Leo Leger.
Of course, NAS and iSCSI technologies have been around for a while, but they are still new formany customers, which is why tutorials like this are so important.
