These disk capacities can have up to 25x times their effective capacity with IBM's HyperFactorin-line deduplication capability. So the smallest 7TB model could be as effective as 175TB of traditionaldisk storage.
IBM Tivoli Storage Manager (TSM) v6
After years and years in development, IBM announces[TSM v6]. Here's a quick summary of the key features:
DB2 instead of an internal database
For years, people have complained that IBM used its own internal relational database. This was becausewhen TSM was first launched back in 1993, the DB2 did not have all the features on all of the various server platforms that TSM needed. Today, DB2is the leading relational database on all the key platforms that TSM server runs on, and therefore good enough for use within Tivoli Storage Manager. If you don't already have DB2, it is included for use with TSM v6.1 at no additional charge. Do you have to become a DB2 expert to use TSM? No! The TSM administration commands have been updated to hide all the complexity of DB2 away, behind the scenes. You now just use TSM commands to administer the database,as you did before. IBM will provide conversion utilities to help existing TSM customers migrate to thisnew database environment.
Better Operational Reporting
Another big complaint was that TSM had fixed reporting, and administrators that wanted customized reportsoften had to resort to purchasing third party products. With the change over to DB2, TSM now enables youto create your own reports using Eclipse's Business Intelligence and Reporting Tools[BIRT]! If you haven't used BIRT, you can downloada free open source copy and start playing around with its capabilities. This is combined with a revamped GUI that provides a customizable dashboard using IBM's Integrated Solutions Console (ISC)infrastructure.
Lastly, IBM has incorporated deduplication capability within the TSM v6.1 software for its own diskstorage pools. This is done in a post-process manner so as to dedupe all of your legacy backup dataas well, not just the new stuff, without impacting the current TSM server performance.
At this point, you might be thinking "Wait, what about IBM TS7650 ProtecTIER deduplication?" which is really two questions.
Can I use TSM v6.1 with IBM TS7650 ProtecTIER?
Yes, however since TSM progressive incremental method is vastly more efficientthan other backup products like Veritas NetBackup or EMC Legato NetWorker, the TS7650 may only get 10x reductionof TSM backups, versus up to 25x with full-backups-every-night backup schemes. TSM only dedupes itsdisk storage pools, so it won't dedupe data directed at tape systems like the TS7650 or othertape libraries. This avoids the "double dedupe" concern.
When should I use TSM's software version versus TS7650's hardware deduplication?
This is a positioning question. For now, the cut-over point is about 10TB per night backup processing. If youbackup more than 10TB per night, TS7650 hardware may be the better approach. If you are a smaller customer nowhere near that volume of data, then using TSM v6.1 software deduplication may be a morecost-effective solution. If you start small, and grow beyond 10TB per night, it is easy to bring ina TS7650 into an existing TSM environment and migrate the data over.
If you run TSM server on a logical partition (LPAR) or virtual guest OS under VMware ESX, Xen or Microsoft'sHyper-V environment, why should you have to license it for the whole box? With TSM v6.1, you nowcan pay for only the amount of processors you use, down to a single core even.If you currently run TSM v5 on z/OS, you can migrate over to TSM v6.1 server for Linux on System z totake advantage of cost savings using IFL engines.
IBM Tivoli Key Lifecycle Manager (TKLM) v1.0
Don't let the "v1.0" scare you, this is the successor to IBM's Encryption Key Manager (EKM) that hasthousands of clients using today with IBM encrypting tape drives. The new TKLM adds support for full disk encryption (FDE) drives--like those for the DS8000 I mentioned in [yesterday's post]--as well as new features to support key rotation for compliance and business controls.
IBM Tivoli Storage Productivity Center
Last, but not least, we have IBM Tivoli Storage Productivity Center [TSPC]. No, that is not a typo. IBM is renaming IBM TotalStorage Productivity Center to Tivoli Storage Productivity Center toavoid trademark conflicts with the [Professional Golfer's Association].
This is not just renaming existing product. Here some key improvements:
TSPC brings back together Productivity Center Standard Edition (Disk, Tape, SAN and Data) with Productivity Center for Replication, which were separate at birth a few years ago.
TSPC adds support for IBM's Storage Enterprise Resource Planner[SERP] from theNovusCG acquisition.
End-to-end view for EMC storage devices connected to supported servers via EMC Powerpath multipathing driver. As customers switch away from EMC Control Center over to IBM's Productivity Center, IBM can continue to provide support for existing EMC gear.
Of course, IBM will still offer IBM System Storage Productivity Center[SSPC] which is a piece of hardware pre-installed with Productivity Center software.
Hopefully, you can now see why I had to split up all these announcements into separate posts acrossmultiple days!
Wrapping up my week's discussion on Business Continuity, I've had lots of interest in myopinion stated earlier this week that it is good to separate programs from data, and thatthis simplifies the recovery process, and that the Windows operating system can fit in a partition as small asthe 15.8GB solid state drive we just announced for BladeCenter. It worked for me, and I will use this post to show you how to get it done.
Disclaimer: This is based entirely on what I know and have experienced with my IBM Thinkpad T60 running Windows XP, and is meant as a guide. If you are running with different hardware or different operating system software, some steps may vary.
(Warning: Windows Vista apparently handles data, Dual Boot, andPartitions differently. These steps may not work for Vista)
For this project, I have a DVD/CD burner in my Ultra-Bay, a stack of black CDs and DVDs, and a USB-attached 320GB external disk drive.
I like to backup the master boot record to one file, and then the rest of the C: drive to a series of 690MB compressed chunks. These can be directed to the USB-attached drive, and then later burned onto CDrom, or pack 6 files per DVD.Most USB-attached drives are formatted to FAT32 file system, which doesn't support any chunks greater than 2GB, so splitting these up into 690MB is well below that limit.
You can learn more about these commands here and here.
Step 1 - Defrag your C: drive
From Windows, right-click on your Recycle Bin and select "Empty Recycle Bin".
Click Start->Programs->Accessories->System Tools->Disk Defragmenter. Select C: drive and push the Analyze button. You will see a bunch of red, blue and white vertical bars. If there are any greenbars, we need to fix that. The following worked for me:
Right-click "My Computer" and select Properties. Select Advanced, then press "Settings" buttonunder Performance. Select Advanced tab and press the "Change" button under Virtual Memory.Select "No Paging File" and press the "Set" button. Virtual memory lets you have many programs open, moving memory back and forth between your RAM and hard disk.
Click Start->Control Panel->Performance and Maintenance->Power Options. On the Hibernate tab,make sure the "Enable Hibernation" box is un-checked. I don't use Hibernate, as it seems likeit takes just as long to come back from Hibernation as it does to just boot Windows normally.
Reboot your system to Windows.
If all went well, Windows will have deleted both pagefile.sys and hiberfil.sys, the twomost common unmovable files, and free up 2GB of space. You can run just fine without either of these features, but if you want them back, we will put them back on Step 6 below.
Go back to Disk Defragmenter, verify there are no green bars, andproceed by pressing the "Defragment" button. If there are still some green bars,you can proceed cautiously (you can always restore from your backup right?), or seek professional help.
Step 2 - Resize your C: drive
When the defrag is done, we are ready to re-size your file system. This can be done with commercial software like Partition Magic.If you don't have this, you can use open source software. Burn yourself the Gparted LiveCD.This is another Linux LiveCD, and is similar to Partition Magic.
Either way, re-size the C: drive smaller. In theory, you can shrink it down to 15GB if this is a fresh install of Windows, and there is no data on it. If you have lots of data, and the drive wasnearly full, only resize the C: drive smaller by 2GB. That is how much we freed upfrom the unmovable files, so that should be safe.
You could do steps 2 and 3 while you are here, but I don't recommend it. Just re-size C:press the "Apply" button, reboot into Windows, and verify everything starts correctly before going to the next step.
Step 3 - Create Extended Paritition and Logical D: drive
You can only have FOUR partitions, either Primary for programs, or Extended for data. However, theExtended partition can act as a container of one or more logical partitions.
Get back into Partition Magic or Gparted program, and in the unused space freed up from re-sizing inthe last step, create a new extended/logical partition. For now, just have one logical inside theextended, but I have co-workers who have two logical partitions, D: for data, and E: for their e-mailfrom Lotus Notes. You can always add more logical partitions later.
I selected "NTFS" type for the D: drive. In years past, people chose the older FAT32 type, but this has some limitations, but allowed read/write capability from DOS, OS/2, and Linux.Windows XP can only format up to 32GB partitions of FAT32, and each file cannot be bigger than 2GB.I have files bigger than that. Linux can now read/write NTFS file systems directly, using the new NTFS-3Gdriver, so that is no longer an issue.
Step 4 - Format drive D: as NTFS
Just because you have told your partitioning program that D: was NTFS type, you stillhave to put a file system on it.
Click Start->Control Panel->Performance and Maintenance->Computer Management. Under Storage, select Disk Management. Right-click your D: drive and choose format.Make sure the "Perform Quick Format" box is un-checked, so that it peforms slowly.
Step 5 - Move data from C: to D: drive
Create two directories, "D:\documents" and "D:\notes\data", either through explorer, or in a commandline window with "MKDIR documents notes\data" command.
Move files from c:\notes\data to d:\notes\data, and any folder in your "My Documents" over to d:\documents.
(If you have more data than the size of the D: drive, copy over what you can, run another defrag, resize your C: drive even smaller with Partition Magic or Gparted, Reboot, verify Windows is still working,resize your D: bigger, and repeat the process until you have all of your data moved over.)
To inform Lotus Notes that all of your data is now on the D: drive, use NOTEPAD to edit notes.ini and change the Directory line to "Directory=D:\notes\data". If you have a special signature file, leave it in C:\notes directory.
Once all of your data is moved over to D:\documents, right-click on "My Documents" and select Properties. Change the target to "D:\documents" and press "Move" button. Now, whenever you select "My Documents", youwill be on your D: drive instead.
Step 6 - Take A Fresh Backup
If you use IBM Tivoli Storage Manager, now would be a good time to re-evaluate your "dsm.opt" file that listswhat drives and sub-directories to backup. Take a backup, and verify your data is being backed up correctly.
With the USB-attached, backup both C: and D: drives. I leave my USB drive back in Tucson. For a backup copywhile traveling, go to IBM Rescue and Recovery and take a C:-only backup to DVD. Make sure D: drive box is un-checked. Now, if I ever need to reinstall Windows, because of file system corruption or virus, I can do this from my one bootable CD plus 2 DVDs, which I can easily carry with me in my laptop bag, leaving all my data on the D: drive in tact.
In the worst case, if I had to re-format the whole drive or get a replacement disk, I can restore C: and thenrestore the few individual data files I need from IBM Tivoli Storage Manager, or small USB key/thumbdrive,delaying a full recovery until I return to Tucson.
Lastly, if you want, reactivate "Virtual Memory" and "Hibernation" features that we disabled in Step 1.
As with Business Continuity in the data center, planning in this manner can help you get back "up and running"quickly in the event of a disaster.
Chris Evans over at Storage Architect posts aboutHardware Replacement Lifecycle Update, on how storage virtualization can helpwith storage hardware replacemement. He makes two points that I would like to comment on.
... indeed products such as USP, SVC and Invista can help in this regard. However at some stage even the virtualisation tools need replacing and the problem remains, although in a different place.
Knowing that replacement of technologies at all levels are inevitable, IBM System Storage SAN Volume Controlleris actually designed to allow cluster non-disruptive upgrade, which we announcedMay 2006.
The process is quite elegant. The SVC consists of one or more node-pairs, and can be upgraded while the systemis up and running by replacing nodes one at a time in a sequence of suspend and resume. All of the mapping tablesare loaded onto the new nodes from the rest of the still active nodes.
I was hoping as part of the USP-V announcement HDS would indicate how they intend to help customers migrate from an existing USP which is virtualising storage, but alas it didn't happen.
Unlike the SVC, once cannot just upgrade the USP in place and make it into a USP-V. While it might be possible tounplug external disk from the old USP, and re-plug into the new USP-V, what do you do about the internal disk data?I doubt you can just move drawers and trays of disk from the old to the new. The data has to be moved some other way.
Some have asked why not just put an SVC in front of both the old USP and the new USP-V and transfer the data that way.While SVC does support virtualizing the old USP device, IBM is still testing the new USP-V as a managed device, and so this solution is not yet available, and would only apply to the LUNs in the USP-V, not the volumes specifically formatted for System i or System z.
An alternative is to take advantage of IBM's Data Mobility Services, the result of our recentacquisition of SofTek. IBM can help you both mainframe and distributed systems data from any device, to any device.
In a typical four year lifecycle of storage arrays, it might take six months or so to fill up the box, and might takeas much as a year at the end to move the data out to other equipment. SVC can greatly reduce both of these, so that you can take immediate advantage of new equipment as soon as possible, and keep using it for close to the full four years,migrating weeks or days before your lease expires.
Continuing my week's theme on Innovations that matter, I thought I would tackle energy efficiency and the recent excitement over the Smart car.
USA Today had an article [America crazy about breadbox on wheels called Smart car]. This car weighs only 2400 pounds, gets a respectable 33 MPG City,and 40 MPG Highway, with a list price of $11,590 US dollars. These have been in Europe for some time now.The "Smart" name comes from combining the S from Swatch, the M from Mercedes and ART. The car was designed byNicholas Hayek, founder of the SWATCH wristwatch line, and manufactured by Daimler, who also makes Mercedes cars.
We have many communities here in Tucson that people drive street-legal golf carts. People don't realize but bothelectric and electric/gas hybrid golf carts have been around for a long time. Some of the nicer golf carts run forabout $7,000 US dollars, with a shelf on the back that can hold two sets of golf clubs, or groceries.Of course, you would never take a golf cart on the highway, so that is where the Smart car comes in, with a 10gallon tank, could easily get you from one major city to another.
Like golf carts, the Smart-for-Two model being sold in the US will hold only two people, which is perfect for manyAmerican families. The standard 4-person or 5-person sedan is too big for most DINKS (Dual Income, No Kids), and other families with kids often opt for the 7-person SUV instead.
It is good to see that energy consumption is finally getting the attention it deserves. IBM recently announced some exciting offerings to help data centers manage their energy consumption:
IBM Systems Director Active Energy Manager V3.1 [AEM]:
A new, key component of IBM's [Cool Blue portfolio] offering, AEM helps clients manage and even potentially lower energy costs. According to Gartner, insufficient power and excessive heat remain the greatest challenges in the data center. With AEM, IT managers can understand exact power/cooling costs, manage the efficiency of the current environment and reduce energy costs. AEM is the only energy management software tool that can provide clients with a single view of the actual power usage across multiple IBM platforms, including x86, blades, Power and storage systems, with plans to extend support to the mainframe.
IBM Usage and Accounting Manager Virtualization Edition V7.1 [UAV]for System p and System x:
UAV gives IT managers more information to manage data center costs. These powerful usage management tools are designed to accurately measure, analyze, and report resource utilization of virtualized/consolidated/shared resources. With UAV, IT managers can better manage costs and justify new systems by determining who is using how much of which resource; assessing the cost of an IT service or application; and accurately charging each user or department. Working with AEM capabilities, it will also allow tracking of energy consumption costs by server and by user. This level of reporting eliminates a key inhibitor to the adoption of virtualization and consolidation and further differentiates IBM systems.
This solution -- ideal for heterogenous IT shops -- serves as an accurate measurement tool underlying billing processes and SLA compliance. UAM provides usage-based accounting and charging for virtually any IT resources across the enterprise -- ranging from mainframes to virtualized servers to storage networks and more. The Usage and Accounting Manager Virtualization offerings seamlessly integrate into it.
Whether you are trying to reduce energy consumption in your data center, or in your transportation around town, these innovations can help you stay "green".
My how time flies! The month is almost over, and people are asking if I plan to discuss my [New Years' Resolutions]. For those readers new to my blog, you can review the [resolutions I made in prior years]. I started blogging about my New Year's resolutions back in 2007 because IBM has a "black-out" period before it announces its year-end financial results, and I can't talk about IBM itself during that time.
"Tests done since 1933 show that people who talk about their intentions are less likely to make them happen.
Announcing your plans to others satisfies your self-identity just enough that you're less motivated to do the hard work needed.
In 1933, W. Mahler found that if a person announced the solution to a problem, and was acknowledged by others, it was now in the brain as a 'social reality', even if the solution hadn't actually been achieved."
The solution for this? Spread out your resolutions throughout the year. That is the advice from Jonah Lehrer in his Wall Street Journal article [Blame it on the Brain]. Here is an excerpt:
"Willpower, like a bicep, can only exert itself so long before it gives out; it's an extremely limited mental resource.
Given its limitations, New Year's resolutions are exactly the wrong way to change our behavior. It makes no sense to try to quit smoking and lose weight at the same time, or to clean the apartment and give up wine in the same month. Instead, we should respect the feebleness of self-control, and spread our resolutions out over the entire year. Human routines are stubborn things, which helps explain why 88% of all resolutions end in failure, according to a 2007 survey of over 3,000 people conducted by the British psychologist Richard Wiseman. Bad habits are hard to break—and they're impossible to break if we try to break them all at once."
Based on those two articles, I focused last year on a single resolution, to lose weight. It worked, I lost some weight, not as much as I wanted, and certainly not for the usual eat-less/exercise-more reasons.
First, I tried Tim Ferris' [Four Hour Body] diet, and I had every intention to post about my progress throughout the year, but that didn't happen. The diet involved eating a restricted diet for six days--including beans, green vegetables, and lean meats--then having one cheat day where you eat a whole bunch of the bad foods you weren't allowed the prior week. The problem I had was that I got so used to eating the same way six days a week, that I forgot to cheat! On this diet, cheating is not optional, it is mandatory. Mo, on the other hand, had no problem with the cheat days, and even extended this to cheat afternoons and cheat evenings!
Mid-year, I saw the movie [Forks Over Knives]. I consulted with my doctor, and switched over to a plant-based, whole-foods diet with his approval. This is basically [dietary veganism]: no eggs, no dairy, no meat, no fish, no poultry. What's left? Lots of slow carbs like beans, spinach and quinoa, that I had already learned to cook and eat earlier on Tim Ferriss' diet, without the stress of remembering to cheat on the weekend.
The nice thing about this diet is that you can eat a lot more than usual, so you are never hungry. The bad news is that I developed a vitamin deficiency, and so my doctor asked me to switch to a relaxed mostly-vegetarian diet, with some eggs, some fish, some meat, and lots of vitamin supplements.
I thought I would start 2012 with a bunch of funny resolutions, like the ones in [Chuck & Beans], but I decided to keep things on a serious level. If you've made resolutions, do not tell anyone what they are, and try focusing on a single one at a time.
For all of you who had a bad year in 2011, I hope you have a much better one in 2012!
(Note: I am neither a medical doctor nor registered dietician. I can share with you ideas that have worked for me, that might help you achieve your goals. I strongly suggest you read books and consult with medical experts as necessary.)
Here are key attributes of my ideal diet:
It is an ongoing "life-style" diet. I want a diet that will help me maintain my desired weight for the rest of my life. I don't want one diet to lose weight, and another diet to gain it all back.
Easy to follow at home, at work, at friend's houses, and at restaurants. By easy, I mean that I can enjoy the food, and eat it in front of co-workers and clients without drawing ridicule.
Does not merely involve substituting each one food with a "healthier" imitation. The controversy over [WhoNu? Cookies] is a good example. These cookies are delicious, look and taste like [Oreo cookies], but claim to be healthier. According to the box, a serving size of three WhoNu cookies have the fiber equivalent of a bowl of oatmeal, the calcium of a glass of milk, and the Vitamin C of a cup of bluepberries. Several bloggers have [compared the ingredients and nutrition facts].
Provides my body enough essential amino acids, fats, vitamins and calories. The diet can include any vitamins or other supplements that are needed to make it a complete.
Over the years, I have tried out the following diets. Here is my experience with each one:
The Zone Diet
Dr. Barry Sears created [the Zone diet] to help diabetics, and it turned out to be good for lots of other people. The "zone" refers to a balance of hormones in your bloodstream that can be achieved if you eat the right ratio of carbs, proteins and fats in every meal. The plan is based on a "block" consisting of 9g of carb, 7g of protein, and 1.5g of fat.
Meals on this plan are merely combining the same number of blocks from each category. Four ounces of beef steak, a cup of kidney beans, and two tbsp of sour cream represents a 4-block meal. The number of blocks per day you are allowed to eat is based on the amount of lean body mass that determines your protein requirements. It was 14 blocks for me.
Pros: I liked this diet, it worked for me. In addition to three meals a day, you can snack between meals, so long as the snacks were also balanced.
Cons: Everything had to be weighed or measured. Difficult to choose meals at restaurants that meet the ratio requirements.
The Four-Hour Body Diet
Fellow blogger Tim Ferriss published the diet that has worked for him for the past seven years. Some call this a "slow-carb" diet. He has helped people [Lose 20 lbs of fat in 30 days without exercise]. The rules are fairly simple:
Rule 1: Do not eat any "white" starchy foods: rice, pasta, bread, cereal, potatoes. Non-white versions of these are also forbidden, so no brown rice, brown bread or green pasta!
Rule 2: All meals are a combination of leans, beans and greens. The leans are low-fat animal-based proteins like egg whites, fish and meat. Beans can be a variety of legumes. Greens can be a wide variety of fruits and vegetables that aren't in the "white" category above.
Rule 3: Eat the same meals over and over again, with breakfast within the first 30 minutes of waking up. The idea here is to eliminate the desire to eat by taking away variety. Once you realize that food is just fuel and building blocks for your body, you can get away from the emotional issues of food.
Rule 4: Don't drink your calories. Avoid any liquid with calories, including milk, fruit juice and soft drinks. Tim makes an exception for red wine, which is good for your health.
Rule 5: Take one day off per week, a "dieters gone wild" cheat day. Pick a day, say Saturday, and that day you can eat anything you want, pizza, tacos, fried Twinkies. It is not that cheating is allowed one day a week, but is required for its affect on metabolism, to avoid [ketosis].
This last rule was perhaps the strangest part of the diet. The intended side-benefit was that if you could look forward to a day in the near future to have something you crave, it would give you the willpower to pass it up today. The boost in carbs also resets your metabolism, so that your body doesn't think it is in starvation mode.
Mo and I got popcorn and large soft drinks at the movie theaters on those days. Stocking "cheat food" in your house just adds extra temptation. Trying to schedule our social life around our cheat days proved quite difficult. As a result, "cheat days" turned into cheat weekends and cheat evenings.
Pros: I liked this diet, it worked for me, but it didn't work for Mo.
Cons: Having gone to chef school, I like to prepare a wide variety of meals. I enjoy food, and variety is the spice of life. Also, I often eat breakfast with clients, which means that I will not be able to eat within 30 minutes of waking up (unless I eat breakfast twice!).
The Forks-over-Knives Diet
After watching the movie [Forks over Knives], I decided to try a plant-based, whole-food vegetarian diet. This is basically a vegetarian diet, but discourages dairy, bread, pasta and refined grains.
I was surprised to learn that you can get enough protein on such a diet. It can be done. Rice and beans are shelf-stable, so you can stock up with fewer trips to the grocery store, and eat very inexpensively.
Pros: I liked this diet, I was able to stick with it, and enjoy the meals. Many restaurants in Tucson accomodate vegetarians with substitutions.
Cons: I didn't lose any weight on this diet. I had difficult time trying to combine foods to make complete proteins. I had vitamin deficiency, and had to take multi-vitamin and other supplements to compensate.
The Paleo Diet
The [Paleo diet] reflects the fact that humans have been around for over 200,000 years, but grains, dairy and other processed foods have only been around for the past 10,000 years. Our genetic code is just not designed for these new foods.
Basically, if a hunter-gather could have "hunted it" or "gathered it", then it can be eaten. The diet consists of eggs, fish, fresh meats, poultry, vegetables, fruits, berries, nuts and seeds. It does not include dairy, bread, pasta, wheat, rye, barley, soy, oats, rice, corn, quinoa, beans, products made from processed meats or refined grains.
As for measurements and proportions, I try to eat at least 90g of Protein, and try to eat less than 150g of Carbs. The diet fits well with the foods that I eat in restaurants with clients, the food we are served at work, and the foods that I can prepare at home.
Pros: I like this diet, it is the one that I am currently on.
Cons: I missing putting half-and-half cream in my coffee! Occasionally, I crave some mac-and-cheese, beans-and-rice, a slice of apple pie, or simply a peanut butter and jelly sandwich.
If you have any experiences with these diets, or a different diet that worked for you, please post a comment below!
I’ve just returned from the IBM Tivoli Pulse conference in Las Vegas – a meeting of over 4000 customers, partners, and IBM employees. ... There was a lot to digest, but three of the major themes caught my attention, and my imagination. ... First, IBM put a huge push behind their Dynamic Infrastructure initiative. Sounds like so many other automation and autonomic initiatives of the past, right? Well, things are getting better, and “dynamic” is becoming more of a realistic possibility, especially with the emergence of cloud computing and cloud services models. ... Second, a lot of time was spent on IBM’s Service Management Industry Solutions. When I first heard of this, my thought was that IBM was creating solutions for the Service Management industry (i.e. food services, janitorial services, hospitality services). But this is much larger than that – much, much larger. IBM is taking their unique ability to pair business (non-IT) expertise with IT consulting, planning, and technology delivery, and constructing (careful – here comes the “f” word) frameworks for several vertical industry segments. ... IBM is perhaps the only organization in the world that can take this on fully and hope to deliver a meaningful result. But beyond that, this represents a huge opportunity for IT professionals to become the transformation agents within their own organizations, contributing at a whole new level. ... Lastly, I was really impressed by IBM’s Smarter Planet initiative. The primary thought here was that the key to a greener planet is to take inefficiencies out of just about every form of business through the intelligent application and deployment of technology. At first I was thinking this was just another marketing initiative, but in the course of this event, listening to the keynotes and talking to a number of IBM execs, it became apparent that this is a substantial cultural shift within IBM itself. Just think about that for a moment – when 400,000 employees all change their direction and focus, their sheer mass is going to make a noticeable difference. ... Magic (Johnson) gave an excellent talk, and reminded the audience that you should do two things no matter what your job or role. First, service starts with knowing your customers – not just who they are, but what they do and what is important to them. And second – always over-deliver. Go that extra step. Exceed expectations. The boost in loyalty, goodwill, and improved customer relationships will be well worth the effort. Good thoughts to keep with us….
If you missed Pulse 2009, perhaps because your company has put a clamp down on travel expenses, you are in luck! IBM is hosting the "Dynamic Infrastructure Forum" March 3-4, 2009, on your computer. This is an IBM Virtual event, no travel required! [Register Today!]
Continuing my business trip through Asia, I have left Chengdu, China, and am now in Kuala Lumpur, Malaysia.
On Sunday, a colleague and I went to the famous Petronas Twin Towers, which a few years ago were officially the tallestbuildings in the world. If you get there early enough in the day, and wait in line for a few hours, you can get a ticket permitting you to go up to the "Skybridge" on the 41st floor that connects the two buildings. The views are stunning, and I am glad to have done this.(If you are afraid of heights, get cured by facing your fears with skydiving)
You would think that a question as simple as "Which is the tallest building in the world?" could easily be answered, given that buildings remain fixed in one place and do not drastically shrink or get taller over time or weather conditions, and the unit of height, the "meter", is an officially accepted standard in all countries, defined as the distance traveled by light in absolute vacuum in 1/299,792,458 of a second.
The controversy stems around two key areas of dispute:
What constitutes a building?
A building is a structure intended for continuous human occupancy, as opposed to the dozens ofradio and television broadcasting towers which measure over 600 meters in height. The Petronas Twin Towers is occupied by a variety of business tenants and would qualify as a building. Radio and Television towers are not intended for occupation, and should not be considered.
Where do you start measuring, and where do you stop?
Since 1969, the height was generally based on a building's height from the sidewalk level of the main entrance to the architectural top of the building. The "architectural top" included towers, spires (but not antennas), masts or flagpoles. Should the measurements be only to the top to the highest inhabitable floor?
What if the building has many more floors below ground level? What if the building exists in a body of water, should sidewalk level equate to water level, and at low tide or high tide? (Laugh now, but this might happen sooner than you think!)
To bring some sanity to these comparisons, the Council on Tall Buildings and Urban Habitat has tried to standardize the terms and definitions to makecomparisons between buildings fair. Why does all this matter whose building is tallest? It matters in twoways:
People and companies are willing to pay more to be a tenant in tall towers, affording a luxurious bird's-eyeview to impress friends, partners and clients, and so the rankings can influence purchase or leasing prices of floorspace in these buildings.
Architects and engineers involved in building these structures want to list these on their resume.These buildings are an impressive feat of engineering, and the teams involved collaborate in a global mannerto accomplish them. If an architecture or engineeering company can build the world's tallest building, you can trust themto build one for you. The rankings can help drive revenues in generating demand for services and offerings.
What does any of this have to do with storage? Two weeks ago, IBM and the Storage Performance Councilanswered the question "Which is the fastest disk system?" with apress release. Customers thatcare about performance of their most mission critical applications are often willing to pay a premium to run theirapplications on the fastest disk system, and the IBM System Storage SAN Volume Controller, built through aglobal collaboration of architects and engineers across several countries, is (in my opinion at least) an impressive feat of storage engineering.
Today, fellow IBMer Ken Hannigan celebrated his 25th year anniversary with IBM, which inducts him into the IBM Quarter Century Club[QCC]. I was surprised to hear that there are over 900 QCC members currently residing in Arizona. In the past, QCC was shortly followed by retirement,but in these economic times, it marks a mid-point in one's career.
I met Ken back in 1988, I was working on DFHSM and he was part of theDFDSS team that moved from San Jose, California to Tucson, Arizona.Later, Ken and I would work in the same department as architects forthe DFSMS product that included DFSMShsm and DFSMSdss components.
Ken was then offered a chance to lead the effort to launch a new productfrom an internal project called Workstation Data Save Facility (WDSF) thatwas changed to Data Facility Distributed Storage Manager (DFDSM),then renamed to ADSTAR Distributed Storage Manager (ADSM), and finally tothe name it has today: [IBM Tivoli Storage Manager].
Over the years, Ken's had some interesting experiences. Two examples:
Saving the Democracy of Peru
During a hotly contested election in the Latin American country of Peru, there were technical problems with the ballot records. Management needed someone from Tucson to go, and my namewas floated around, since I spoke Spanish fluently. My schedule did not permit,so they sent Ken instead. Ken was able to recover the lost ballot information and avoid a revolution.
Assisted with the Technical team for a Major Motion Picture
Ken was part of the IBM technical team that helped [DreamWorks SKG] producethe movie [The Prince of Egypt],a major animated motion picture. IBM is heavily involved in the digital mediacommunity, and was instrumental in helping film-makers set up theirinformation infrastructure.
Ken has been one of my best friends over the past twenty years. I introduced him to hiswife, and was the best man at his wedding. It is quality people like Ken that makeworking at IBM so special.
Wrapping up this week's theme on why the System z10 EC mainframe can replace so many older, smaller,underutilized x86 boxes.This was all started to help fellow bloggers Jon Toigo of DrunkenData and Jeff Savit from Sun Microsystemsunderstand our IBM press release that we put out last February on this machine with my post[Yes, Jon, there is a mainframe that can help replace 1500 x86 servers] and my follow uppost [Virtualization, Carpools and Marathons"].The computations were based on running 1500 unique workloads as Linux guests under z/VM, and notrunning them as z/OS applications.
My colleagues in IBM Poughkeepsierecommended these books to provide more insight and in-depth understanding. Looks like some interesting summer reading. I put in quotes thesections I excerpted from the synopsis I found for each.
"From Microsoft to IBM, Compaq to Sun to DEC, virtually every large computer company now uses clustering as a key strategy for high-availability, high-performance computing. This book tells you why-and how. It cuts through the marketing hype and techno-religious wars surrounding parallel processing, delivering the practical information you need to purchase, market, plan or design servers and other high-performance computing systems.
Microsoft Cluster Services ("Wolfpack")
IBM Parallel Sysplex and SP systems
DEC OpenVMS Cluster and Memory Channel
Tandem ServerNet and Himalaya
Intel Virtual Interface Architecture
Symmetric Multiprocessors (SMPs) and NUMA systems"
Fellow IBM author Gregory Pfister worked in IBM Austin as a Senior Technical Staff Member focused on parallel processing issues, but I never met him in person. He points out that workloads fall into regions called parallel hell, parallel nirvana, and parallel purgatory. Careful examination of machine designs and benchmark definitions will show that the “industry standard benchmarks" fall largely in parallel nirvana and parallel purgatory. Large UNIX machines tend to be designed for these benchmarks and so are particularly well suited to parallel purgatory. Clusters of distributed systems do very well in parallel nirvana. The mainframe resides in parallel hell as do its primary workloads. The current confusion is where virtualization takes workloads, since there are no good benchmarks for it.
"In these days of shortened fiscal horizons and contracted time-to-market schedules, traditional approaches to capacity planning are often seen by management as tending to inflate their production schedules. Rather than giving up in the face of this kind of relentless pressure to get things done faster, Guerrilla Capacity Planning facilitates rapid forecasting of capacity requirements based on the opportunistic use of whatever performance data and tools are available in such a way that management insight is expanded but their schedules are not."
Neil Gunther points out that vendor claims of near linear scaling are not to be trusted and shows a method to “derate” scaling claims. His suggested scaling values for data base servers is closer IBM's LSPR-like scaling model, than TPC-C or SPEC scaling. I had mentioned that "While a 1-way z10 EC can handle 920 MIPS, the 64-way can only handle 30,657 MIPS."in my post, but still people felt I was using "linear scaling". Linear scaling would mean that if a 1Ghz single-core AMD Opteron can do four(4) MIPS, and an one-way z10 EC can do 920 MIPS, than one might assume that 1GHz dual-core AMD could do eight(8) MIPS, and the largest 64-way z10 EC can do theoretically 64 x 920 = 58,880 MIPS. The reality is closer to 6.866 and 30,657 MIPS, respectively.
This was never an IBM-vs-Sun debate. One could easily make the same argument that a large Sun or HP system could replace a bunch of small 2-way x86 servers from Dell. Both types of servers have their place and purpose, and IBMsells both to meet the different needs of our clients. The savings are in total cost of ownership, reducing powerand cooling costs, floorspace, software licenses, administration costs, and outages.
I hope we covered enough information so that Jeff can go back about talking about Sun products, and I can go backto talk about IBM storage products.
