Well, there's little to no chance we'll get snow in Tucson the rest of this year, so I built a snowman out in Second Life. That's my avatar on the right, andI am an eightbar specialist. Eightbar refers to our logo.
This was part of an IBM "Holiday Party" where dozens of IBMers met "in the virtual world" to participate in 3D competitions,I entered the "Build a Snowman" competition, since I am still a beginner at this. This was whatI was able to come up with in 20 minutes that we had to get it done. Why I made mine out of woodwith different colors was so that I could stand out from the crowd. Everyone else used traditionalwhite snowy textures.
Others had a more challenging "Build a Snow Globe" where you have to write scripts to get thelittle snow flakes to move around. This for the advanced builders of our group.
This is still new, emerging technology, but eventually, Second Life and other MMOs could be used to market products,that people can view from all three dimensions, talk to a technical specialist, and get all questions answered.It could be used for education, shopping around, and collaborating with others.
Anyways, I haven't heard the results, but I had fun anyways.

Our industry is full of acronyms, and sometimes spelling out what words an acronym stands for is not enough to explain it fully.
It reminds me of an old story within IBM. A customer engineer (or "CE" for short) was repairing an air-cooled server, and found the failing part being a "FAN". Not knowing what this stood for, he looked up the acronym in the offical "IBM list of acronyms" and found that it stood for "Forced Air Network". Apparently, so many people did not realize that a FAN was just a "fan" that they needed to add an entry to remind people what this little motorized propeller was for.
This brings me to Tony Asaro's Fun with FAN blog entry which mentions yet another definition for FAN, that of "File Area Network". The concept is not new, but some developments this year help make it more a reality.
To join the rest of the world, new types of data set were created for the z/OS operating system, known as HFS and zFS. These held file systems in the sense we know them today, comparable in hierarchical organization of files on Windows, Linux and UNIX platforms. These could be linked and mounted together in larger hierarchical structures across the sysplex.
The concept of files and file systems is a fairly new concept. Prior to this, applications read and wrote directly in terms of blocks, typically fixed length multiples of 512 bytes. For a while, database management systems offered a choice, direct block access or file level access. The former may have offered slightly better performance, but the latter was easier to administer. Without file system, specialized tools were often required to diagnose and fix problems on block-oriented "raw logical" volumes.
This launched a "my file system is better than yours" war which continues today. The official standard is POSIX, but every file system tries to give some proprietary advantage by offering unique features. Sun's file system offers support for "sparse" files, which is ideal for certain mathematical processing of tables. Microsoft's NTFS offers biult-in compression, designed for the laptop user. IBM's JFS2 and Linux's EXT3 file systems support journaling, which tracks updates to file system structures in a separate journal to minimize data corruption in the event of a power outage, and thus speed up the re-boot process. Anyone who has ever waited for a "Scan Disk" or "fsck" process to finish knows what I'm talking about. Of course, if an application deviates from POSIX standards, and exploits some unique feature of a file system, it then limits its portability and market appeal.
The two competing NAS file systems are also different. Common Internet File System (CIFS) was developed initially by IBM and Microsoft to provide interoperability between DOS, Windows and OS/2. Meanwhile, Network File System (NFS) was the darling of nearly every UNIX and Linux distribution, and even has clients on operating platforms as diverse as MacOS, i5/OS, and z/OS. Today, nearly every platform supports one or both of these standards.
Bottom line, file systems are here to stay. Any slight advantages to use raw logical volumes for databases and applications are losing out to the robust set of file system utilities that can be used across a broad set of platforms and applications.Read More]

For those of you worried about my mysterious absence on the blogosphere, I am getting better. Sorry for not posting much lately, I have had more serious issues to worry about. I am awaiting results on whether I have Dengue fever from Brazil, Avian flu from Thailand, Malaria from Kenya, or perhaps it is just food poisoning from the otherwise fabulous French cuisine I ate last week in the South Pacific. Well, I am back in town for a while, and hopefully will recover to full health, and have some time to reflect my thoughts on storage topics.
Speaking of which, a lot has happened while I was out. Let's take a quick look.

Hello Everyone! I am back from my safari vacation in Kenya.
One of the interesting parts of the journey was to visit a village of the Samburu tribe. Each village is a circle of huts surrounded by thorned branches to keep the wild lions out. In the center is another ring of thorned branches to keep all the cattle, sheep and goats.
One of the tribewomen invited us to show us her home. Each hut is made of sticks, stuck into the ground and then woven with other sticks, then covered in cow dung along the walls, and scraps of cardboard and newspaper as the roof.
Although the hut looks small from the outside, it was surprisingly roomy inside; it was divided into four rooms or partitions. The first was for the adults, the second for children, and the third for newborn animals and sometimes relatives visiting from other villages.
I asked what was the fourth room used for, and of course, her answer was: Storage.[Read More]

Well,This is completely off-topic, but now that I have a bluetooth-enabled Thinkpad T60, I have been interested in this new wireless technology. I have a bluetooth cell phone, a bluetooth wireless headset, and my thinkpad, and they all work together seemlessly. I am able to speak on my cell phone through my headset, listen to music and videos on my laptop through my headset, and even dial in to the IBM network through my cell phone, all without any cables!
A variation of the Wi-Fi soup-cantenna has emerged to intercepting bluetooth signals. Check out this coolBlueSniper Rifle
Now that's innovation.[Read More]

For those who missed it, IBM announced last Tuesday encryption capability for the TS1120 drive, our enterprise tape drive that read and write 3592 cartridges. Do you need special cartridges for this? No! Use the sames ones you have already been using!
You can read more about it www.

Well, it's Tuesday again, and you know what that means? IBM Announcements!
It has been 71 days since my last post, and people were beginning to worry. Did Tony with the lottery? Was Tony hit by a bus? Did Tony get abducted by aliens from another planet? No, none of these things happened.
I got a new job! I am still working with IBM Systems, but now am one of the Event Content Managers for the [IBM Systems Technical University] events, or TechU for short. For those who have attended these events, I have taken over for Glenn Anderson, who retired December 31, 2018.
Last year, the IBM TechU team asked me to present eight topics at an event in Johannesburg, South Africa, as a last-minute replacement for other speakers. While there, Glenn Anderson mentioned to me that he was planning to retire. "Do you know anyone interested in taking over for me?" he asked.
I jumped at the chance to apply for the job! There was stiff competition, but after three rounds of interviews and background checks, I was offered the position! This all happened after the zTechU event in Hollywood, Florida last October, so if this is the first you have heard of it, you are not alone.
For those wondering "What about the IBM Tucson Client Experience Center?" you have good reason to ask. I had worked at the center for the past 12 years, the last six as the chief subject matter expert (SME) for all things IBM System Storage. Who is going to replace me? The job posting is still open, and the new manager, John Zupetz, has been reviewing resumes.
As time permits, I will continue to do storage briefings to help out during this transition, both here in Tucson, Arizona, as well as outbound to various client and IBM locations. I have also offered to help train whomever gets hired for the job.
In my new role, I will be managing TechU events, selecting topics, accepting speakers, scheduling sessions, and even presenting sessions at the events themselves. I will be focused on IBM Z and LinuxONE mainframe servers and related Storage solutions, but will also manage sessions on soft skills for IT Leadership and Professional Development.
We plan to have about 18 events this year, spanning countries across six continents! I just finished smaller 3-day events in Istanbul, Turkey and Cairo, Egypt, and am now working on larger events to be held in Dubai, Atlanta, and Berlin!
Shameless plug! Registration is open for these TechU events. I plan to be at all three, if you want to meet me in person!
In the meantime, I have decided to take on two extra co-authors for this blog. Let me introduce them to you:
I have spent the last 10 weeks working with the IBM developerWorks team converting from a single-author blog to a multi-author blog. I had no idea it would be so complicated to re-work the HTML templates, acquire all the legal and managerial approvals, and then authorize additional contributors!
I look forward to working with my new co-authors!
