Mark your calednars! If you live or work anywhere near Australia or New Zealand, I will be presenting in a 7-city series in both countries. Here is my schedule:
I am just one of the speakers. We will have at each location the local IBM team and IBM clients giving testimonials. All the speakers will be available afterward for Q&A. It's shaping up to be an exciting series of events!
Well, it's that Back-To-School time again! Mo's thirteen-year-old reluctantly enters the eight grade, still upset the summer ended so abruptly. Richard's nephew returns to the University of Arizona for another year. Natalie has chosen to move to Phoenix and pursue a post-grad degree at Arizona State University. They all have two things in common, they all want a new computer, and they are all on a budget.
Fellow blogger Bob Sutor (IBM) pointed me to an excellent article on [How to Build Your Own $200 PC], which reminded me of the [XS server I built] for my 2008 Google Summer of Code project with the One Laptop per Child organization. Now that the project is over, I have upgraded it to Ubuntu Desktop 10.04 LTS, known as Lucid Lynx. Building your own PC with your student is a great learning experience in itself. Of course, this is just the computer itself, you still need to buy the keyboard, mouse and video monitor separately, if you don't already have these.
If you are not interested in building a PC from scratch, consider taking an old Windows-based PC and installing Linux to bring it new life. Many of the older PCs don't have enough processor or memory to run Windows Vista or the latest Windows 7, but they will all run Linux.
(If you think your old system has resale value, try checking out the ["trade-in estimator"] at the BestBuy website to straighten out your misperception. However, if you do decide to sell your system, consider replacing the disk drive with a fresh empty one, or wipe the old drive clean with one of the many free Linux utilities. Jason Striegel on Engadget has a nice [HOWTO Erase your old hard disk drive] article. If you don't have your original manufacturer's Windows installation discs, installing Linux instead may help keep you out of legal hot water.)
Depending on what your school projects require, you want to make sure that you can use a printer or scanner with your Linux system. Don't buy a printer unless it is supported by Linux. The Linux Foundation maintains a [Printer Compatability database]. Printing was one of the first things I got working for my Linux-based OLPC laptop, which I documented in my December 2007 post [Printing on XO Laptop with CUPS and LPR] and got a surprising following over at [OLPC News].
To reduce paper, many schools are having students email their assignments, or use Cloud Computing services like Google Docs. Both the University of Arizona and Arizona State University use Google Docs, and the students I have talked with love the idea. Whether they use a Mac, Linux or Windows PC, all students can access Google Docs through their browser. An alternative to Google Docs is Windows Live Skydrive, which has the option to upload and edit the latest Office format documents from the Firefox browser on Linux. Both offer you the option to upload GBs of files, which could be helpful transferring data from an old PC to a new one.
Lastly, there are many free video games for Linux, for when you need to take a break from all that studying. Ever since IBM's [36-page Global Innovation Outlook 2.0] study showed that playing video games made you a better business leader, I have been encouraging all students that I tutor or mentor that playing games is a more valuable use of your time than watching television. IBM considers video games the [future of learning]. Even the [Violent Video Games are Good for Kids]. It is no wonder that IBM provides the technology that runs all the major game platforms, including Microsoft Xbox360, Nintendo Wii and Sony PlayStation.
(FTC disclosure: I work for IBM. IBM has working relationships with Apple, Google, Microsoft, Nintendo and Sony. I use both Google Docs and Microsoft Live Skydrive for personal use, and base my recommendations purely on my own experience. I own stock in IBM, Google and Apple. I have friends and family that work at Microsoft. I own an Apple Mac Mini and Sony PlayStation. I was a Linux developer earlier in my IBM career. IBM considers Linux a strategic operating system for both personal and professional use. IBM has selected Firefox as its standard browser internally for all employees. I run Linux both at home and at the office. I graduated from the University of Arizona, and have friends who either work or take classes there, as well as at Arizona State University.)
Linux skills are marketable and growing more in demand. Linux is used in everything from cellphones to mainframes, as well as many IBM storage devices such as the IBM SAN Volume Controller, XIV and ProtecTIER data deduplication solution. In addition to writing term papers, spreadsheets and presentations with OpenOffice, your Linux PC can help you learn programming skills, web design, and database administration.
To all the students in my life, I wish you all good things in the upcoming school year!

Wrapping up my coverage of the annual [2010 System Storage Technical University], I attended what might be perhaps the best session of the conference. Jim Nolting, IBM Semiconductor Manufacturing Engineer, presented the new IBM zEnterprise mainframe, "A New Dimension in Computing", under the Federal track.
The zEnterprises debunks the "one processor fits all" myth. For some I/O-intensive workloads, the mainframe continues to be the most cost-effective platform. However, there are other workloads where a memory-rich Intel or AMD x86 instance might be the best fit, and yet other workloads where the high number of parallel threads of reduced instruction set computing [RISC] such as IBM's POWER7 processor is more cost-effective. The IBM zEnterprise combines all three processor types into a single system, so that you can now run each workload on the processor that is optimized for that workload.
What does this all mean for the IT industry? First, the zEnterprise is perfectly positioned for [three-tier architecture] applications. A typical example could be a client-facing web-server on x86, talking to business logic running on POWER7, which in turn talks to database on z/OS in the z196 mainframe. Second, the zEnterprise is well-positioned for government agencies looking to modernize their operations and significantly reduce costs, corporations looking to consolidate data centers, and service providers looking to deploy public cloud offerings. Third, IBM storage is a great fit for the zEnterprise, with the IBM DS8000 series, XIV, SONAS and Information Archive accessible from both z196 and zBX servers.
To learn more, see the [12-page brochure] or review the collection of [IBM Redbooks]. Check out the [IBM Conferences schedule] for an event near you. Next year, the IBM Storage University will be held July 18-22, 2011 in Orlando, Flordia.
Continuing my coverage of the annual [2010 System Storage Technical University], I attended some sessions from the System x and Federal track side of this conference.
I find it amusing that server people limit themselves to server sessions, and storage people to storage sessions. Sometimes, you have to step "outside your comfort zone" and learn something new, something different. Open your eyes and look around a bit. You might just be surprised what you find.
(FTC note: I work for IBM. IBM considers Novell a strategic Linux partner. Novell did not provide me a copy of Platespin Recon, I have no experience using it, and I mention it only in context of the presentation made. IBM resells Avocent solutions, and we use LCM gear in the Tucson Executive Briefing Center.)
Continuing my coverage of the annual [2010 System Storage Technical University], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, they were called "Meet the Experts", one for mainframe storage, and the other for storage attached to distributed systems. This year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This post provides a recap of the Storage Hardware free-for-all.
The emcee for the event was Scott Drummond. The other experts on the panel included Dan Thompson, Carlos Pratt, Jack Arnold, Jim Blue, Scott Schroder, Ed Baker, Mike Wood, Steve Branch, Randy Arseneau, Tony Abete, Jim Fisher, Scott Wein, Rob Wilson, Jason Auvenshine, Dave Canan, Al Watson, and myself, yours truly, Tony Pearson.What can I do to improve performance on my DS8100 disk system? It is running a mix of sequential batch processing and my medical application (EPIC). I have 16GB of cache and everything is formatted as RAID-5.
We are familiar with EPIC. It does not "play well with others", so IBM recommends you consider dedicating resources for just the EPIC data. Also consider RAID-10 instead for the EPIC data.How do I evaluate IBM storage solutions in regards to [PCI-DSS] requirements.
Well, we are not lawyers, and some aspects of the PCI-DSS requirements are outside the storage realm. In March 2010, IBM was named ["Best Security Company"] by SC Magazine, and we have secure storage solutions for both disk and tape systems. IBM DS8000 and DS5000 series offer Full Disk Encryption (FDE) disk drives. IBM LTO-4/LTO-5 and TS1120/TS1130 tape drives meet FIPS requirements for encryption. We will provide you contact information on an encryption expert to address the other parts of your PCI-DSS specific concerns.My telco will only offer FCIP routing for long-distance disk replication, but my CIO wants to use Fibre Channel routing over CWDM, what do I do?
IBM XIV, DS8000 and DS5000 all support FC-based long distance replication across CWDM. However, if you don't have dark fiber, and your telco won't provide this option, you may need to re-negotiate your options.My DS4800 sometimes reboots repeatedly, what should I do.
This was a known problem with microcode level 760.28, it was detecting a failed drive. You need to replace the drive, and upgrade to the latest microcode.Should I use VMware snapshots or DS5000 FlashCopy?
VMware snapshots are not free, you need to upgrade to the appropriate level of VMware to get this function, and it would be limited to your VMware data only. The advantage of DS5000 FlashCopy is that it applies to all of your operating systems and hypervisors in use, and eliminates the consumption of VMware overhead. It provides crash-consistent copies of your data. If your DS5000 disk system is dedicated to VMware, then you may want to compare costs versus trade-offs.Any truth to the rumor that Fibre Channel protocol will be replaced by SAS?
SAS has some definite cost advantages, but is limited to 8 meters in length. Therefore, you will see more and more usage of SAS within storage devices, but outside the box, there will continue to be Fibre Channel, including FCP, FICON and FCoE. The Fibre Channel Industry Alliance [FCIA] has a healthy roadmap for 16 Gbps support and 20 Gbps interswitch link (ISL) connections.What about Fibre Channel drives, are these going away?
We need to differentiate the connector from the drive itself. Manufacturers are able to produce 10K and 15K RPM drives with SAS instead of FC connectors. While many have suggested that a "Flash-and-Stash" approach of SSD+SATA would eliminate the need for high-speed drives, IBM predicts that there just won't be enough SSD produced to meet the performance needs of our clients over the next five years, so 15K RPM drives, more likely with SAS instead of FC connectors, will continue to be deployed for the next five years.We'd like more advanced hands-on labs, and to have the certification exams be more product-specific rather than exams for midrange disk or enterprise disk that are too wide-ranging.
Ok, we will take that feedback to the conference organizers.IBM Tivoli Storage Manager is focused on disaster recovery from tape, how do I incorporate remote disk replication.
This is IBM's Unified Recovery Management, based on the seven tiers of disaster recovery established in 1983 at GUIDE conference. You can combine local recovery with FastBack, data center server recovery with TSM and FlashCopy manager, and combine that with IBM Tivoli Storage Productivity Center for Replication (TPC-R), GDOC and GDPS to manage disk replication across business continuity/disaster recovery (BC/DR) locations.IBM Tivoli Storage Productivity Center for Replication only manages the LUNs, what about server failover and mapping the new servers to the replicated LUNs?
There are seven tiers of disaster recovery. The sixth tier is to manage the storage replication only, as TPC-R does. The seventh tier adds full server and network failover. For that you need something like IBM GDPS or GDOC that adds this capability.All of my other vendor kit has bold advertising, prominent lettering, neon lights, bright colors, but our IBM kit is just black, often not even identifying the specific make or model, just "IBM" or "IBM System Storage".
IBM has opted for simplified packaging and our sleek, signature "raven black" color, and pass these savings on to you.Bring back the SHARK fins!
We will bring that feedback to our development team. ("Shark" was the codename for IBM's ESS 800 disk model. Fiberglass "fins" were made as promotional items and placed on top of ESS 800 disk systems to help "identify them" on the data center floor. Unfortunately, professional golfer [<a hrefWhere is Infiniband?
Like SAS, Infiniband had limited distance, about 10 to 15 meters, which proved unusable for server-to-storage network connections across data center floorspace. However, there are now 150 meter optical cables available, and you will find Infiniband used in server-to-server communications and inside storage systems. IBM SONAS uses Infiniband today internally. IBM DCS9900 offers Infiniband host-attachment for HPC customers.We need midrange storage for our mainframe please?
In addition to the IBM System Storage DS8000 series, the IBM SAN Volume Controller and IBM XIV are able to connect to Linux on System z mainframes.We need "Do's and Don'ts" on which software to run with which hardware.
IBM [Redbooks] are a good source for that, and we prioritize our efforts based on all those cards and letters you send the IBM Redbooks team.The new TPC v4 reporting tool requires a bit of a learning curve.
The new reporting tool, based on Eclipse's Business Intelligence Reporting Tool [BIRT], is now standardized across the most of the Tivoli portfolio. Check out the [Tivoli Common Reporting] community page for assistance.An unfortunate side-effect of using server virtualization like VMware is that it worsens management and backup issues. We now have many guests on each blade server.
IBM is the leading reseller of VMware, and understands that VMware adds an added layer of complexity. Thankfully, IBM Tivoli Storage Manager backups uses a lightweight agent. IBM [System Director VMcontrol] can help you manage a variety of hypervisor environments.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.
