Today was a special day! IBM launched the world's first "Global Archive Solutions Center" in Guadalajara, Mexico.We had a formal "ribbon cutting", shown here were the following dignitaries (from left to right):
Eugenio Godard, IBM Guadalajara site level executive
Andy Monshaw, IBM General Manager of IBM System Storage
Cindy Grossman, IBM VP of Tape and Archive solutions
Luis Guillermo Martinez Mora, Secretary of economic development for the state of Jalisco, Mexico
José Décurnex, IBM General Manager for the country of Mexico
In the morning, we had a series of speeches from Cindy Grossman, Andy Monshaw, Eugenio Godard, and Federico Lepe (technology advisor for the governor for the state of Jalisco, Mexico).
While the hordes of press journalists, analysts and clients were taking the lab tour, we took a snap of thefront entrance. The day was packed with activity.
After the lab tour, IBMers Clod Barrera and Craig Butler presented to the analysts.
Cindy Grossman explained why IBM created a solutions center specific to archive solutions, and why wechose Guadalajara for its location.
I presented the pains and challenges companies are facing, and why they should partner with IBM forarchive solutions to address those requirements
Harley Puckett and I split the group. Harley is my colleague at the IBM Tucson ExecutiveBriefing Center who was the focal point for the various aspects of launching for the past eight months.He presented and moderated the presentations and demos to a collection of prospective clients.
That's me on the left, with Harley on the right.
I moderated a series of speakers to press and analysts. These included:
Mark LaBelle, Spectrum Health server and storage manager, and Steve Lawrence, Spectrum Health image solutions architect, presented their success story using IBM Grid Medical Archive Solution (GMAS). [Spectrum Health] manages seven hospitals and 130 service locations in Michigan, USA.
Mark Uren, ABSA technical architect, presented their success story working with IBM in deploying their Information Lifecycle Management (ILM) which includes Enterprise Content Management and archiving. Mark flew in all the way from Johannesburg, South Africa. [ABSA] is the financial services subsidiary of Barclay's serving theAfrican continent.
Jeffrey Beallor, president of [Global Data Vaulting], presented his success story as both a client and IBM Business Partner, offering backup and archiving solutions through "Software as a Service" (SaaS) business model. GlobalData Vaulting has its data centers in Canada, but provides services to clients worldwide.
We had a Q&A panel with the company representatives from Spectrum Health, ABSA, and Global Data Vaulting; followed by a Q&A panel with the collection of IBM executives to take questions from the press and analysts.Special thanks to Cyntia, Daniela, Carlos, Raul and Salvador for their help in making this a successful event!

Continuing my summary of Pulse 2008, the premiere service managementconference focusing on IBM Tivoli solutions, I attended and presentedbreakout sessions on Monday afternoon.
Tivoli Storage "State-of-the-Subgroup" update
Kelly Beavers, IBM director of Tivoli Storage, presented the first breakout for all of the Tivoli Storage subgroup.Tivoli has several subgroups, but Tivoli Storage leads with revenuesand profits over all the others.Tivoli storage has top performing business partner channel of anysubgroup in IBM's Software Group division.IBM is world's #1 provider of storage vendor (hardware, softwareand services), so this came to no surprise to most of the audience.
Looking at just the Storage Software segment, it is estimatedthat customers will spend $3.5 billion US dollars more in the year 2011 than they did last year in 2007. IBM is #2 or #3 in eachof the four major categories: Data Protection, Replication, Infrastructure management, and Resource management. In eachcategory, IBM is growing market share, often taking away share fromthe established leaders.
There was a lot of excitement over the FilesX acquisition.I am still trying to learn more about this, but what I have gathered so far is that it can:
Like turning a "knob", you can adjust the level of backupprotection from traditional discrete scheduled backups, to morefrequent snapshots, to continuous data protection (CDP). Inthe past, you often used separate products or features to dothese three.
Perform "instantaneous restore" by performing a virtualmount of the backup copy. This gives the appearance that therestore is complete.
This year marks the 15th anniversary of IBM Tivoli StorageManager (TSM), with over 20,000 customers. Also, this yearmarks the 6th year for IBM SAN Volume Controller, having soldover 12,000 SVC engines to over 4,000 customers.
Data Protection Strategies
Greg Tevis, IBM software architect for Tivoli Technical Strategy,and I presented this overview of data protection. We coveredthree key areas:
Protecting against unethical tampering with Non-erasable, Non-rewriteable (NENR) storage solutions
Protecting against unauthorized access with encryption ondisk and tape
Protecting against unexpected loss or corruption with theseven "Business Continuity" tiers
There was so much interest in the first two topics that weonly had about 9 minutes left to cover the third! Fortunately,Business Continuity will be covered in more detail throughoutthe week.
Henk de Ruiter from ABN Amro bank presented his success storyimplementing Information Lifecycle Management (ILM) across hisvarious data centers using IBM systems, software and services.
Making your Disk Systems more Efficient and Flexible
I did not come up with the titles of these presentations. Theteam that did specifically chose to focus on the "business value"rather than the "products and services" being presented. Inthis session, Dave Merbach, IBM software architect, and I presentedhow SAN Volume Controller (SVC), TotalStorage Productivity Center,System Storage Productivity Center, Tivoli Provisioning Managerand Tivoli Storage Process Manager work to make your disk storagemore efficient and flexible.
I attended the main tent sessions on Day 2 (Monday). The focuswas on Visibility, Control and Automation.
Steve is IBM senior VP and Group Executive of the IBM Software Group, and presented someinsightful statistics from the IBM Global Technology Outlookstudy, some recent IBM wins, and other nuggets of IT trivia:
In 2001, there were about 60 million transistors per humanbeing. By 2010, this is estimated to increase to one billion per human
In 2005, there were about 1.3 billion RFID tags, by 2010this is estimated to grow to over 30 billion
IBM helped the City of Stockholm, Sweden, reduce traffic congestion 20-25% using computer technology
Only about 25% data is original, the remaining75% is replicated
In 2007, there were approximately 281 Exabytes (EB), expected to increase to 1800 EB by the year 2011
70 percent of unstructured data is user-created content, but 85 percent of this will be managed by enterprises
Only 20% of data is subject to compliance rules and standards, and about 30% subject to security applications
Human error is the primary reason for breaches, with34% of organizations experiencing a major breach in 2006
10% of IT budget is energy costs (power and cooling), and thiscould rise to 50% in the next decade
30 to 60 percent of energy is wasted. During the next 5 years, people will spend as much on energy as they will on new hardware purchases.
Al Zollar is the General Manager of IBM Tivoli. He discussedthe 20 some recent software acquisitions, including Encentuate and FilesX earlier this year.
"The time has come to fully industrialize operations" -- Al Zollar
What did Al mean about "industrizalize"? This is theclosed-loop approach of continuous improvement, including design, delivery and management.
Al used several examples from other industries:
Henry Ford used standardized parts and processautomation. Assembly of an automatobile went from 12 hours by master craftsmen, to delivering a new model T every 23 seconds off anassembly line.
Power generation was developed by Thomas Edison. A satellite picture showed the extent of the [Blackout of 2003 in Northeast US and Canada]. The time for "smart grid" has arrived, making sensors andmeters more intelligent. This allows non-essential IP-enabled appliances in our home or office to be turned off to reduce energy consumption.
[McCarran International Airport] integrated the management of 13,000 assets with IBM Tivoli Maximo Enterprise Asset Management (EAM) software, and was able to increase revenues through more accurate charge-back. Unlike traditional EnterpriseResource Planning (ERP) applications, EAM offers the deep management of four areas: production equipment, facilities, transportation, and IT.
When compared to these other industries, management of IT is in itsinfancy. The expansion of [Web 2.0] and Service-Oriented Architecture [SOA] is driving this need.What people need is a "new enterprise data center" that IBM Tivoli software can help you manage across operational boundaries. IBM can integrate through open standards with management software from Cisco, Sun, OracleMicrosoft, CA, HP, BMC Software, Alcatel Lucent, and SAP.Together with our ecosystems of technology partners, IBM ismeeting these challenges.
IBM clients have achieved return on investment from gettingbetter control of their environment. This week there are client experience presentations Sandia National Labs, Spirit AeroSystems, Bank of America, and BT Converged communication services.
Chris O'Connor used some of his staff as "actors" to show an incredible live demo of various Tivoli and Maximo products for the mythical launch of "Project Vitalize", thenew online web store for a new "Aero Z bike" from the mythical VCA Bike and Motorcycle company.
Shoel Perelman played the role of "CIO".The CIO locked down all spending, and asked the IT staff to make the shift from bricks-and-mortar to web salesof this new product on in 15 months. While the company andsituation were mythical, all the products that were part of thelive demo are all readily available.The CIO had three goals:
What do we have? where is it? what's connected to what?Traditionally, these would be answered from lists in spreadsheets.The CIO had a goal to deploy IBM Tivoli Application DependenceDiscover Manager (TADDM) which discovered all hardware and software,with an easy to understand view, and how each piece serves the business applications.
Each of the teams have processes, and needed them consistent andrepeatable, tightly linked together. Time is often wasted on thephone coordinating IT changes. For this, the CIO had a goalto deploy Tivoli Change and Configuration Management Database (CCMDB) for "strict change control".The process dashboard is accessible for all teams, to see how all projects are progressing. There is also aCompliance dashboard, which identifies all changes by role, clearly spelling out who can do what.
There is a lot of computerized machinery, Manufacturing assets and robotics. The CIO set a goal to "do more with existing people", and needed to automate key processes.Sales rep wanted to add a new distributor to key web portal.This was all done through their "service catalog", When they needed to deploy a new application, they were able to find servers with available capacity and adjust using automatic provisioning. Thanks to IBM, the IT staff no longer get paged at 3am in the morning, and fewer days are spent in the "war room". They now have confidence that thelaunch will be successful.
Ritika Gunnar played the role of "Operations manager". She highlightedfive areas:
"Service viewer" dashboard with green/yellow/red indicators forall of their edge, application and datbase servers. This allowsher to get data 4-5 times faster and more accurate.
Tivoli Enterprise Portal eliminates bouncingaround various products.
Tivoli Common Reporting for CPU utilization of all systems, helps find excess capacity usingIBM Tivoli Monitor
On average, 85 percent of problems are caused by IT changes to the environment. IBM can help find dependencies, so that changes in one area do not impact other areas unexpectedly
Process Automation will Show changes that have been completed, in progress, or overdue.She can see all steps in a task or change request. A"workflow" automates all the key steps that need to be taken.
Laura Knapp played the role of "Facilities manager". She wanted to See all processes that apply to her work using a role-based process dashboard. The advantage of using IBM is that it changes work habits, reduces overtimeby 42 percent, improves morale. The IT staff now works as team,collaborates more, and jobs get done faster with fewer mistakes.Employees are online, accessing, monitoring and managing dataquicker. In days not weeks.
IBM Tivoli Enterprise Console (TEP) served as a common vehicle.She was able to pull up floor plan online, displaying all of the managed assets and mapped features. With the temperature overlay from Maximo Spatial, she was able to review hot spots on data center floor. Heat can cause servers to fail or shut down.
Power utilization chart at peak loadsCan now anticipate, predict and watch power consumption,and were able to justify replacement with newer, more energy-efficient equipment.
The CIO got back on stage, and explained the great success of thelaunch. They use Webstore usage tracking, security tools tracking all new registrations, and trackingserver and storage load.It now only takes hours, not weeks, to add new business partners and distributors.Tivoli Service Quality Assurance toolstrack all orders placed, processed, and shipped.Faster responsiveness is competitive advantage. TheirIT department is no longer seen as stodgy group, but as a world classorganization.
The live demo showed how IBM can help clients with rapid decisionmaking, speed and accuracy of change processes, and automation to take actions quickly. The result is a strong return on investment (ROI).
Liz Smith, IBM General Manager of Infrastructure Services, presented the results of an IBM survey to CEOs and CIOs asking questions like: What is the next big impact? Where are you investing?What will new datacenter look like?
The five key traits they found for companies of the future:
They were hungry for change
Innovative beyond customer imagination
Disruptive by nature
Genuine, not just generous
The IT infrastructure must be secure, reliable, and flexible.Taking care of environment is a corporate responsibility, notjust a way to reduce costs.
The five entry points for IBM Service Management: Integrate, Industrialize,Discover,Monitor and Protect.IBM Service management and compliance are critical for theGlobally Integrated Enterprise, with repeatable, scalable and consistent processes that enablechange to an automated workflow. This reduces errors, risks and costs, and improves productivity.IBM has talent, assets and experience to help any client get there.
Lance lives in Austin, TX, where IBM Tivoli is headquartered,so this made a good choice as a keynote speaker.He is best known for winning seven "Tour de France" bicycle races in a row, but he spoke instead gave an inspirational talk about how he survived cancer.
In 1996, Lance was diagnosed with cancer. Surprisingly, He said it was thegreatest thing that happened to him, and gave him new perspective on his life, family and the sport ofbicycling.Back then, there wasn't a webMD, Google or other Web 2.0 socialnetworking sites for Lance to better understand what he wasgoing through, learn more about treatment options, or find othersgoing through the same ordeal.
After his treatment, he was considered "damaged goods" by manyof the leading European bicycle teams. So, he joined the US Postal Serviceteam, not known for their wins, but often invited to sell TVrights to American audiences. Collaborating with his coachesand other members of his team, he revolutionized the bicycling sport, analyzed everything about the race, and built up morale.He won the first "yellow jersey" in 1999, and did so each yearfor a total of seven wins.
Lance formed the [Livestrong foundation] to help other cancer survivors. Nike came to him and proposed donating 5 million "rubber bracelets"colored yellow to match his seven yellow jerseys, with the name "Livestrong" embossed on them, that his foundation couldthen sell for one dollar apiece to raise funds. What some thought was a silly idea at first has started amovement.At the 2004 Olympics, many athletes from all nations and religious backgrounds, wore these yellow braceletsto show solidarity with this cause.To date, the foundation has sold over 72 million yellow bracelets, and these have served to provide a symbol,a brand, a color identity, to his cause.
He explained that doctor's have a standard speech to cancer survivors.As a patient, you can go out this doorway and never tell anyone,keep the situation private. Or you can go out this other doorway, you tell everybody your story. Lance chose the latter, and he felt it was the best decision he ever made.He wrote a book titled [It's Not About the Bike: My Journey Back to Life].
His call to action for the audience: find out what can you do to make a difference.A million non-governmental organizations[NGO] have started in the past 10 years. Don't just give cash, also give your time and passion.
It seems like I just get out of one conference, and into another. This week I am at Pulse 2008, which combines the best of IBM Tivoli and Maximo into one conference.Like many conferences, this one starts on Sunday, and ends on Thursday.
We're at the Swan and Dolphin hotels at [Walt Disney World] in Orlando, Florida. I've been to several conferences in Orlando, but this is my first time at the Swanand Dolphin. (When I walked into the main lobby, I had a bout of "deja vu". IBM LotusSphere was here last year, and they had a complete replica made in SecondLife!)
If you haven't been to Walt Disney World resorts, whether for a conference or vacation,there are two things you need to know:
Nothing is within a short "walking distance", you need to take a bus or boat to get anywhere
Despite this, you will be doing a lot of walking, so wear comfortable shoes!
Pulse encouraged everyone to blog and take pictures posted onto FlickR, here are a few from Sunday:
Lou and Elizabeth from [Syclo], an IBM Business Partner
Mike and Megha from [Birlasoft] show off their accreditation
Greg Tevis explains FilesX, recently acquired by IBM
I'm glad this is the final day of the IBM Systems Technical Conference (STC08) here in Los Angeles.While I enjoyed the conference, one quickly reaches saturation point with all the information presented.
XIV Architecture Overview
Before this conference, many of the attendees didn't understandIBM's strategy, didn't understand Web 2.0 and Digital archive workloads,and didn't understand why IBM acquired XIV to offer "yet another disk systemthat servers LUNs to distributed server platforms." Brian Shermanchanged all that!
Brian Sherman, IBM Advanced Technical Support (ATS), is part of the exclusive dedicated XIVtechnical team to install these boxes at client locations, so he is very knowledgeable with the technical aspects of the architecture. He presented what the current XIV-branded model that clients can purchase now in select countries, and what the IBM-branded model will change when available worldwide.
Those who missed my earlier series on XIV can find them here:
Beyond this, Brian gave additional information on how thin provisioning, storage pools, disk mirroring, consistency groups, management consoles, and microcode updates are implemented.
N series and VMware Deep Dive
Norm Bogard, IBM Advanced Technical Support, presented why the IBM N series makes such great disk storage for VMware
deployments. This wasclearly labeled as a "deep dive", so anyone who got lost in all of theacronyms could not blame Norm for misrepresentation.
IBM has been doing server virtualization for over 40 years, so it makes sense thatit happens to be the number one reseller of VMware offerings.VMware ESX server is a hypervisor that runs on x86 host, and provides an emulationlayer for "guest Operating Systems". Each guest can hvae one or more virtualdisks, which are represented by VMware as VMDK files. VMware ESX server acceptsread/write requests from the guests, and forwards them on to physical storage.Many of VMware's most exciting features requires storage to be external to thehost machine. [VMotion]allows guests to move from one host to another, [Distributed Resource Scheduler (DRS)]allows a set of hosts to load-balance the guestsacross the hosts, and [High Availability (HA)] allows the guests on a failed hostto be resurrected on a surviving host. All of these require external disk storage.
ESX server allows up to 256 LUNs, attached via FCP and/or iSCSI, and up to 32 NFS mount points. Across LUNs, ESX server uses VMFS file system, which is a clusteredfile system like IBM GPFS that allows multiple hosts to access the same LUNs.ESX server has its own built-in native multipathing driver, and even provides FCP-iSCSIand iSCSI multipathing. In other words, you can have a LUN on an IBM System Storage N series thatis attached over both FCP and iSCSI, so if the SAN switch or HBA fails, ESX servercan failover to the iSCSI connection.
ESX server can use NFS protocol to access the VMDK files instead. While the default is only 8 NFS mount points, you can increase this to 32 mount points. NAS can takeadvantage of Link Aggregate Control Protocol [LACP] groups, what some call "trunking" or "EtherChannel". This is the ability to consolidate multiple streams onto fewer inter-switch Ethernet links, similar to what happens on SAN switches.For the IBM N series, IBM recommends a "fixed" path policy, rather than "most recently used".
IBM recommends disabling SnapShot schedules, and setting the Snap reserve to 0 percent.Why? A snapshot of an ESX server datastore has the VMDK files of many guests, all of which would have had to quiesce or stop to make the data "crash consistent" for theSnapshot of the datastore to even make any sense. So, if you want to take Snapshots, itshould be something you coordinate with the ESX server and its guest OS images, and notscheduled by the N series itself.
If you are running NFS protocol to N series, you can turn off the "accesstime" updates. In normal file systems, when you read a file, it updates the"access time" in the file directory. This can be useful if you are looking forfiles that haven't been read in a while, such as software that migrates infrequentlyaccessed files to tape. Assuming you are not doing that on your N series, you might as well turnoff this feature, and reduce the unnecessary write activity to the IBM N series box.
ESX server can also support "thin provisioning" on the IBM N series. There isa checkbox for "space reserved". Checked means "thick provisioning" and uncheckedmeans "thin provisioning". If you decide to use "thin provisioning" with VMware,you should consider setting AutoSize to automatically increase your datastorewhen needed, and to auto-delete-snap your oldest snapshots first.
The key advantage of using NFS rather than FCP or iSCSI is that it eliminates theuse of the VMFS file system. IBM N series has the WAFL file system instead, andso you don't have to worry about VMFS partition alignment issue. Most VMDK aremisaligned, so the performance is sub-optimal. If you can align each VMDK to a32KB or 64KB boundary (depending on guest OS), then you can get better performance.WAFL does this for you automatically, but VMFS does not. For Windows guests, use "Windows PE" to configurecorrectly-aligned disks. For UNIX or Linux guests, use "fdisk" utility.
What Industry Analysts are saying about IBM
Vic Peltz gave a presentation highlighting the accolades from securities analysts, IT analysts, and newsagencies about IBM and IBM storage products. For example, analysts like that IBM offersmany of the exciting new technologies their clients are demanding, like "thin provisioning", RAID-6 double-drive protection,SATA and Solid State Disk (SSD) drive technology.Analysts also like that IBM is open to non-IBM heterogeneous environments. Whereas EMC Celerra gateways supportonly EMC disk, IBM N series gateways and IBM SAN Volume Controller support a mix of IBM and non-IBM equipment.
Analysts also like IBM's "datacenter-wide" approach to issues like security and "Green IT". Rather than focusingon these issues with individual point solutions, IBM attacks these challenges with a complete"end-to-end" solution approach. A typical 25,000 square foot data center consumes $2.6 million dollars USD in power andcooling today, and IBM has proven technologies to reduce this cost in half. IBM's DS8000 on average consume26.5 to 27.8 percent less electricity than a comparable EMC DMX-4 disk system. IBM's tape systemsconsume less energy than comparable Sun or HP models.
IBM iDataPlex product technical presentation
Vallard Benincosa, IBM Technical Sales Specialist, presented the recently-announced [IBM System x iDataPlex].This is designed for our clients that have thousands of x86 servers, that buy servers "racks at a time", tosupport Web 2.0 and digital archive workloads. The iDataPlex is designed for efficient power and cooling,rapid scalability, and usable server density.
iDataPlex is such a radical design departure, that it might be difficult to describe in words.Most racks take up two floor tiles, each tile is 2 foot by 2 foot square. In that space, a traditionalrack would have servers that were 19 inches wide slide in horizontally, with flashing lights and hot-swappabledisks in the front, and all the power supply, fans and networking connections in the back. Even with IBM BladeCenter,you have chassis in these racks, and then servers slide in vertically in the front, and all of the power supply, fanand networking connections in the back. To access these racks, you have to be able to open the door on boththe front and back. And the cooling has to go through at least 26.5 inches from the front of the equipment to the back.
iDataPlex turns the rack sideways. Instead of two feet wide, and four feet deep, it is four feet wide, and two feet deep.This gives you two 19 inch columns to slide equipment into, and the air only has to travel 15 inches from frontto back. Less distance makes cooling more efficient.
Next, iDataPlex makes only thing in the back the power cord, controlled by an intelligent power distribution unit (iPDU) so you can turnthe power off without having to physically pull the plug. Everything else is serviced from the front door.This means that the back door can now be an optional "Rear Door Heat Exchanger" [RDHX] that is filled with running water to makecooling the rack extremely efficient. Water from a cooler distirubtion unit (CDU) can power about threeto four RDHX doors.
Let's say you wanted to compare traditional racks with iDataPlex for 84 servers. You can put 42 "1U" serversin two racks each, each rack requires 10 kVA (kilo-volt-amps) so you give it two 8.6 kVA feeds each, that is fourfeeds, and at $1500-2000 dollars USD per month, will cost you $6000-8000. The iDataPlex you can fit 84 serversin one 20 kVA rack, with only three 8.6 kVA feeds, saving you $1500-2000 dollars USD per month.
Fans are also improved. Fan efficiency is based on their diameter, so small fans in 1U servers aren't as effective as iDataPlex's 2U fans, saving about 12-49W per server. Whereas typical 1U server racks spend 10-20percent of their energy on the fans, the iDataPlex spends only about 1 percent, saving 8 to 36 kWH per year per rack.
Each 2U chassis snaps into a single power supply and a bank of 2U fans. A "Y"power cord allows you to have one cord for two power supplies. A chassis can hold either two small server "flexnodes"or one big "flexnode". An iDataPlex rack can hold up to 84 small servers or 42 big servers. Since each "Y" cord can power up to four "flexnode" servers, you greatly reduce the number of PDU sockets taken,leaving some sockets available for traditional 1U switches.
The small "flexnode" server can have one 3.5 inch HDD, or two 2.5 inch HDD, either SAS or SATA, and the big "flexnode" can have twice these.If you need more storage, there is a 2U chassis that holds five 3.5 inch HDD or eight 2.5 inch HDD. These areall "simple-swappable" (servers must be powered down to pull out the drives). For hot-swappable drives, a 3Uchassis with twelve 3.5 inch SAS or SATA drives.
The small "flexnode" server has one [PCI Express] slot, the big servers have two. Thesecould be used for [Myrinet] clustering. With only 25W power,the PCI Express slots cannot support graphics cards.
The iDataPlex is managed using the "Extreme Cluster Administration Toolkit" [XCAT]. This is an open source project under Eclipse that IBM contributes to.
Finally was the concept of "pitch". This is the distance from the center of one "cold aisle" to the next "cold aisle".On typical data centers, a pitch is 9 to 11 tiles. With the iDataPlex it is only three tiles when using the RDHX doors, or six tiles without. Most data centers run out of power and cooling before they run out of floor space, so having more dense equipmentdoesn't help if it doesn't also use less electricity.Since the iDataPlex uses 40 percent less power and cooling, you can pack more racks persquare foot of an existing data center floor with the existing power and cooling available. That is what IBM calls "usable density"!
What Did You Say? Effective Questioning and Listening Techniques
Maria L. Anderson, IBM Human Resources Learning, gave this "professional development" talk. I deal with different clients every week, so I fully understand that there is a mix of art and science incrafting the right questions and listening to the responses.The focus was on howto ask better questions and improve the understanding and communication during consultative engagements. Thisinvolves the appropriate mix of closed and open-ended questions, exchanging or prefacing as needed. This wasa good overview of the ERIC technique (Explore, Refine, Influence, and Confirm).
Well, that wraps up my week here in Los Angeles.Special thanks to my two colleagues, Jack Arnold and Glenn Hechler, both from the Tucson Executive Briefing Center,who helped me prepare and review my presentations!
