DOL refreshes server switch hardware

March 31st, 2010

The Department of Labour has issued two tenders for the supply of server and switch hardware.

The servers will be replacing existing devices within DOL’s office computing environment and will be distributed and deployed locally. It prefers to purchase the server hardware via a direct purchase.
DOL currently uses IBM Blade technology with Cisco blade switches and some of the required servers will utilise this investment.

The switch devices will be replacing existing Cisco devices within DOL’s office computing environment. They will be deployed within its 20 local offices and 15 overseas locations.

The deadline for the server replacement is Tuesday, April 13 while the switch tender closes on Friday, April 16.

Aruba rolls the cloud into virtual branch 2.0

March 31st, 2010

Aruba Networks has introduced an update to last year’s Virtual Branch Networking (VBN) product launch. VBN 2.0 combines Aruba’s wireless hardware platform with a unique set of cloud services to secure and improve performance connecting to remote sites. By pulling together a set of partners and leveraging the capabilities of its mobility hardware, Aruba is offering an alternate vision of branch office connectivity and trying to dispel the notion that the only way to deliver app acceleration and security is with dedicated hardware.

To speed up the WAN links between the branch office and corporate, VBN 2.0 now includes Aruba’s Application Acceleration Service (AAS) and Content Delivery Network (CDN). The solution on a server in the data center, as well as its remote access points (RAP) at the endpoints. The endpoints, basically hybrid wireless access points with additional processing capabilities, will do basic network protocol optimization and compression for the common protocols, including web browsing, Windows file staring and Microsoft Exchange. The CDN solution joins in the acceleration by pushing shared data closer to end users, creating a world-wide cache for branch offices to tap into, instead of constantly traveling the WAN links back to the home office.

Similarly, Aruba is approaching content security at branch locations without back-hauling the traffic back to the data center. Traditional web-filtering solutions form a choke point at the enterprise data center, funneling all of a company’s Internet traffic through a single point, then applying corporate policies against it. The downside of this approach, of course, is that web access from a branch location requires that traffic run up and down the site’s WAN or VPN links, adding lag time in the process. Aruba’s Content Security Service (CSS) puts this traffic management, content filtering and antivirus/anti-spam protection in the cloud, sparing the end-user from the multiple hops to reach their web destination.

Lastly, Aruba is offering an alternative to their RAP hardware for remote connectivity. Like its the hardware equivalent, the new Virtual Intranet Access (VIA) client offers users an automatic connection back to the corporate office, but comes in the form of a Windows client, instead of the small hardware RAP solution. While the RAP solution is designed for sharing a common connection with multiple devices, the VIA product is focused on delivering dedicated connectivity for the laptop user.

While it is interesting that these new services are coming from a company typically known for its WLAN products, the approach that Aruba Networks is taking with its new services is far more compelling. With VBN 2.0, Aruba is taking the old “one neck to choke” adage to new heights. Notably, while Aruba will acknowledge that it is working with best-of-breed cloud partners to deliver these services, the company at no point identifies these partners, noting that Aruba will be the single point of contact for these services, an approach that will likely appeal to many enterprise customers. While enterprise IT staff could certainly stitch these services together through a myriad of vendors, the fact that Aruba is bringing these together for them, with guaranteed integration, on existing hardware, and only one support line to call, will be an attraction option.

Diet animation iPad goes kinda flash

March 31st, 2010

Uncle Steve still hates Flash code on any and all Apple hardware. In other news, America has a black president.

Stating the obvious aside, that hasn’t stopped at least one mobile advertising network from bringing a Flash ad-like experience to the iPad. Greystripe now offers an “iFlash” technology which basically transcribes Flash code into iPhone/iPad-friendly content, which they claim have a higher click-through rates than the Flash originals. Currently, Greystripe customers include HP, Burger King, Axe, Dunlop and LeapFrog.

Coupled with Brightcove’s recent HTML5-based streaming video player, it seems that Flash-free necessity really is the “Mother of iNvention

Red hat injects RHEL with new iron love

March 31st, 2010

Red Hat has pushed out another rev of its Linux variant. With Enterprise Linux 5.5, support for the latest processors from Advanced Micro Devices, Intel, and IBM has been back-ported to the Linux 2.6.18 at the heart of the RHEL 5 stack.

According to Tm Burke, vice president of platform engineering at Red Hat, the kernel in RHEL 5.5 has been improved, and it now includes features from more current Linux kernels, so it’s not particularly fair to call it Linux 2.6.18. The point is that any application that was certified to run on Linux 2.6.18 or later, possibly many years ago, will work on RHEL 5.5 and still have support for new hardware like the Power7 processors from IBM that debuted back in February, the “Westmere-EP” Xeon 5600s from Intel that came out two weeks ago, the “Magny-Cours” Opteron 6100s from AMD that launched earlier this week, and the “Nehalem-EX” Xeon 7500s that were announced yesterday.

Because machines based on the Opteron 6100s, Xeon 7500, and Power7 processors all use a form of non-uniform memory access (NUMA) memory sharing across multiple processor sockets and also have multiple cores and caches inside sockets, RHEL 5.5 includes a lot of work that makes the operating system very aware of the system topology so memory allocation and job scheduling is done such that instruction streams and their data are placed as close together as possible. The kernel also has tweaks that try to cram as much work on as few cores as possible, allowing for servers to conserve power as they dial down or quiesce cores in the systems.

The updated RHEL also has a lot of I/O optimizations to take advantage of virtual I/O hardware features in the most current x64 and Power processors, which cuts down on I/O overhead in virtualized environments. In I/O-heavy virtualized workloads where the I/O was virtualized in software, rather than on the chip, the I/O overhead could be as high as 30 per cent, which is unacceptable.

Burke says that with these tweaks for I/O virtualization, which include a feature called Single Root I/O Virtualization (SR-IOV), a guest operating system running inside either a Xen or KVM hypervisor embedded in RHEL 5.5 can drive a 10 Gigabit Ethernet adapter card to its saturation point, and Burke claims this is the only hypervisor environment today that can do this. (That won’t last for long, with RHEL being open source).

While the freestanding KVM hypervisor at the heart of the Red Hat Enterprise Virtualization, or RHEV, product was updated with a beta of its own 2.2 release using the RHEL 5.5 kernel earlier this week, RHEL 5.5 is available today and supports fatter guest virtual machines. The RHEV 2.2 beta can support 16 virtual CPUs and up to 256 GB of memory per guest, but RHEL 5.5 can support 32 physical processor cores and up to 512 GB of memory on either a Xen or KVM guest.

The bare-metal RHEL 5.5 kernel can support up to 1 TB of physical memory and can support well beyond the current top-end 64 sockets delivered today in eight-way Xeon 7500 systems. The open source community has already figured out how to do 512-core NUMA systems for the Itanium chips and is leveraging this work as x64 architectures get fatter. The RHEL 5 kernel has a stunning theoretical maximum of 32,000 threads that it can support, which is well beyond anything any server maker can put into the field in a single system image. Later this year, IBM’s top-end Power 795 systems will have 32 sockets with a total of 256 cores and 1,024 threads.

The largest general-purpose Xeon 7500 machines will have maybe 64-sockets, which means 512 cores and 1,024 threads, and it looks like Itanium 9300 machines will probably top out at 64 sockets as well, but those quad-core chips only have eight threads, so that’s a maximum of 512 threads. AMD is topped out at 40 threads in four-socket boxes with the Opteron 6100s. That will barely tickle the limits of RHEL 5.5.

By the way, RHEL 4 is not getting support for all this new iron, since Red Hat stopped doing major backporting to this early RHEL version six months ago. At some point, says Burke, the changes that would be necessary make new hardware work on the older versions without breaking application compatibility would involve way too much work or not be possible at all.

In general, a RHEL version gets three years of cutting-edge hardware support (roughly updated every six months), one year of transitional support where major hardware enablement and driver work is done, but perhaps not the greatest amount of tuning, and then three years where the version is in maintenance mode, with bug fixes and security patches. The expectation is that RHEL 5 will have a couple more years of hardware maintenance, but it really depends on how radical the hardware changes are in the future. If the changes are too radical, RHEL 5 gets sent to pasture sooner.

In addition to the updated hardware support, RHEL 5.5 has pulled in OpenOffice 3.1, which has better compatibility with Microsoft’s Office 2007 formats, and the Samba print and file server has been updated to work with Windows 7. The SystemTap dynamic tracing tool that is part of the development stack in RHEL has also been enhanced so it can probe and poke C++ applications, rather than just C apps. The GDB debugger also has better support for C++ applications in that it allows developers to debug one thread at a time instead of having to suspend all threads in C++ code at the same time.

From hardware To wetware a potential manufacturing paradigm shift

March 31st, 2010

With the most recent race to find oil in the Falkands, the energy crisis stay top of mind. Some question our ability to adapt to such an impending issue. However, one possible solution might take on a multi-disciplinary approach to the materiality of the biosciences. World Changing recently interviewed interaction designer Alexandra Daisy Ginsberg on her collaboration with the iGEM 2009 team as well as her residency at Synthetic Aesthetics, an exchange program between designers and scientists.

Where this interview is pertinent to the energy crisis is Ginsberg’s design for Growth Assembly, whereby plant life models may offer a different form of manufacturing, moving from hardware to wetware if you will:

We were thinking about manufacturing post oil crisis and what synthetic biology might offer this future. Jim Haseloff at Cambridge University works with plants, not bacteria, researching morphology – the way plants grow – with the aim of one day controlling it. He suggested that, “one day we may be able to grow products inside plants.

Bringing internet to far-flung areas of India

March 31st, 2010

There are more than 80 million internet users in India, who use the World Wide Web for a number of activities, including writing emails, looking for jobs, online banking, trading stocks and even searching for love on countless matrimonial sites.

But so far only about five million people access the internet via broadband, and many Indians are keen to get a faster connection.

Scientists from India’s universities and electricity companies are working to create access via power lines that will allow high-speed connections that are faster than 256Kbps. This will make it much easier for internet users to download movies or music, as well as to watch sport on television and other programs via live streaming.

Young professionals are excited

Samik Moitra, a young IT professional, is looking forward to the development. “It is very difficult to access live streaming of matches because of the low speed and connectivity problems, but it seems this system will solve speed problems.”

Broadband over Power Lines works by transmitting high frequency signals through the same power cables that are used to provide electricity to households.

P.K. Roy from the Bengal Engineering and Science University explains that “the signal comes right from the point of injection into a household socket. A particular gadget called the Customer Premise Equipment is put into the back of a computer so that the Internet can be browsed.”

He adds that the Customer Premise Equipment is a portable device that can be plugged into any socket, thus providing a “Plug and Play” broadband at home.

User-friendly system given the thumbs up by testers

Dilip Sen, the Executive Director of the Calcutta Electric Supply Corporation, lists the advantages: “It doesn’t consume airwaves so it preserves the frequency band, which is a national resource. Secondly, you don’t require any hardware or other infrastructure as it is the same power cable that you have at home.”

90 percent of those who have tested the system in pilot projects rate it as being “excellent” compared to other broadband services that are currently available in India.

Scientists are currently working on international standards for BPL technology. It has already been implemented in parts of Spain and Russia and experts say it stands good chances of taking over the global market.

Revolutionary applications?

Excited engineers are already thinking about the way the system might develop in the future. Some think it will enable people to program household appliances and command them from a distance.

Manju Mukherjee, a working mother, has great expectations: “The system will help me very much as I will be able to use a microwave to warm up food while sitting in my office when my kid comes home.”

However, such applications are only in their pilot stage right now and it might take some time before they become part of everyday life.

Get management buy-in with the windows 7 upgrade project kit

March 31st, 2010

Here’s a scenario that is surely being played out in many IT departments right now:

Back in the early 2000s you successively managed the upgrade of the client side of your IT infrastructure to Windows XP. Sure there were a few bumps in the road, but once you got through those, your company enjoyed increased efficiency due to the new features and vast improvements built into the Windows XP operating system.

Of course, the IT department was happy, but more importantly, upper management was happy with the return on their investment. Based on your recommendations they opened up the purse strings, gave you the funding you needed, and IT infrastructure was allowing the business to run smoothly and efficiently.

When Vista came out you saw the writing on the wall. The operating system had a very troubled development cycle, Windows XP was still performing admirably and meeting all your business expectations, so you felt comfortable taking a wait and see approach. As the problems with Vista unfolded, the IT department was happy that you decided to stay with XP, but more importantly, upper management was happy. They hadn’t wasted money on new hardware and software and the IT infrastructure based on Windows XP clients still met the needs of the business.

Now, Windows 7 is on the scene and Service Pack 1 is right around the corner. Over the past five months you’ve spent a lot of time investigating and testing Windows 7 in your test bed and you’re confident that the new operating system is ready to take your IT infrastructure to the next level. However, you’re not sure how open upper management will be to the idea.

The economy is still a bit shaky, the budget is tight, the stigma of the Vista failure is still fresh, and from their perspective, the current IT infrastructure is still satisfactory. As such, the task of selling an upgrade to Windows 7 won’t be the same as it was for Windows XP.

If you’re going to successfully make a business case to upper management to relinquish the funding and resources that you need for a successful Windows 7 upgrade, you are going to have to lay out your plan using goals and outcomes that make sense to the business-oriented mentality of the folks in upper management.

With these thoughts in mind, I’ve spent the last couple of months looking around for information on how to pull all of this together. And while I have found lots of great resources for putting together such a plan, most of it has been piecemeal.

Recently, I discovered the Windows 7 Upgrade Project Kit from ToolkitCafe and found a complete set of tools for creating a comprehensive Windows 7 upgrade plan that will not only help you get buy-in from upper management but will also help you to orchestrate a very well planned out and successful Windows 7 upgrade. In addition to being a comprehensive package, the kit is well written, very organized, easy to use and understand, and sprinkled with humor in such a way that it takes the edge off, and makes you feel comfortable with, the task at hand.

In this edition of the Windows Vista and Windows 7 Report, I’ll take a look at the Windows 7 Upgrade Project Kit.
An overview

As I explored the Windows 7 Upgrade Project Kit, which is essentially a series of Word and Excel templates, I discovered that a lot of time and effort was put into providing an IT Guy with a set of preplanned, business oriented, documentation and planning tools designed to facilitate the creation of the type of detailed information that the folks in upper management need to see in order to make them feel compelled to buy-in to such a considerable endeavor. (However, it is important to keep in mind that this kit is not a simple fill in the blank sort of tool; it will require time and thoughtful planning to take full advantage of the structure that the templates in this package provide.)

In addition to the goal of getting management buy-in, I discovered that the tools in this kit are designed to help you to quickly get up to speed using new planning and implementation ideas drawn from rapid development methodology, knowledge formation, and problem management techniques. Because these new ideas are imbedded in a real world project rather than being presented in a general fashion, you’ll immediately put them to use as you go. As you recognize your successes along the way, you’ll slowly, but surely, begin to incorporate this new way of thinking into your everyday tasks.

So, what exactly, is in the Windows 7 Upgrade Project Kit? Let’s take a closer look.
The kit

The Windows 7 Upgrade Project Kit consists of 17 templates or tools. More specifically, there are seven standalone Word documents, two standalone Excel spreadsheets, and eight tools that come as both Word documents and Excel spreadsheets. These tools are organized into five categories that will allow you to progressively develop and implement your Windows 7 upgrade plan.

The kit’s home page describes each of the categories in detail and provides links to the set of tools that apply to that category. There is also a document titled General Instructions that provides you with an overview and explains how each of the tools fits into the plan you are developing. Furthermore, each tool in the kit provides very focused and detailed instructions as well as examples and suggestions. As you read through the instructions for each tool, it’s almost as if a trusted mentor is standing right with you every step of the way.
Business Narrative

You know how Windows 7 will transform your aging IT infrastructure into a thing of technological beauty, but to sell it to upper management; you have to sell it in their terms. To help you get to that point, the first three tools in the kit: the Vision Statement Builder, the Business Case Builder, and the Architectural Principles Tool, will provide you with a solid framework on which to organize your ideas and goals from an IT perspective and present them in a business perspective while maintaining a tone that is accessible to both technical and non-technical people.
Project Organization

To help further your pitch, you need to show that not only do you have a good idea, but that you also have a good plan in place to make that idea a reality. That’s where the Project Organization Tool and the Simple Project Planning Tool come into play. Together, these tools will provide you the ability to easily organize your project plan, establish the way the work will be administered, and describe the project team members and their responsibilities.
Implementation Framework

Once you have your project organization in place, you’ll use the Features Checklist, As Built Template, and the Testing Plan tools to begin developing the framework of your Windows 7 upgrade including specific details about the prototypes, pilots, and deployments. In other words, these tools are designed to make it easy to translate the business vision into a solid upgrade path.
Communications

All the hard work in planning means nothing if the lines of communication aren’t clearly laid out for all involved – including senior management, department managers, and your IT staff. Using the Communications Plan, Checkpoint Report, Highlight Report, and Exception Report tools will allow you to lay out a methodology and ensure that clear and effective communications are easily maintained throughout the entire process.
Wisdom Building

Throughout the entire upgrade process you are going to hit bumps in the road – that’s a given. However, the way in which you navigate those bumps can make a big difference in the degree of your overall success. In order to help you make the best of those difficulties and learn from them as you go, you can use any or all of the following tools: The Risk Matrix Template, the Issues Template, the Request for Change Template, the Risk Issue Change Log, and the Support FAQ.
Get the Windows 7 Upgrade Project Kit

With its set of 17 specific tools, the Windows 7 Upgrade Project Kit from ToolkitCafe is one of the most comprehensive packages that I’ve found. To learn more about this kit, which sells for $199, just point your browser to the Windows 7 Upgrade Project Kit page on the ToolkitCafe Web site.
