IBM to assault users with virtualization technology

Hit over head by abstraction


IBM this week created a product out of a marketing term, announcing plans to roll out a suite of goods to link servers and software from various vendors called the IBM Virtualization Engine.

Sadly, the Virtualization Engine appears to have some nasty marketing elements still swirling about it. IBM bills the product set as "advanced cross-platform technology meant to vastly improve the economics and industrial-strength operations of IT." Loosely translated, this means IBM will begin planting pieces of Virtualization Engine in various software and hardware products, hoping to improve overall data center management. High priorities with the technology include managing hardware from different vendors with IBM software and being able to run more applications on single servers.

The Virtualization Engine is just an extension of what IBM has been doing on the storage side of the house with its SAN Volume Controller and SAN File System products and what the industry has been doing as a whole.

Companies are trying to develop management software that can tap into any kind of hardware from any vendor and chop that hardware up like never before. This generally entails creating software that divides servers and storage systems into fine partitions and then layering management software on top of the boxes that automates typically manual configuration tasks.

Despite what vendors claim, we're still at the very early stages of this process. Big boys such as IBM, HP, Sun Microsystems and EMC are racing against smaller firms to pump out actual products that work as billed.

Concrete example

At present, IBM is only previewing the Virtualization Engine technology. The technology will appear first in a new set of iSeries servers due out in the next two months. Then, later this year, IBM will include the technology with a new line of pSeries Unix servers and later with xSeries servers, storage systems and software products.

The most concrete example of the Virtualization Engine technology being provided by IBM is a new class of partitioning technology for the upcoming Power5-based servers.

At present, customers can only create one partition per processor on Power4-based pSeries and iSeries boxes. When the Power5 systems rollout, however, customers will be able to create up to 10 partitions per processor. Customers will also be able to divvy up bandwidth between partitions.

This type of technology is somewhat of a mainframe copy. IBM's zSeries systems can run almost countless partitions and share networking resources.

The technology is also similar to what Sun has rolled out with its N1 Grid Containers - another virtualization play. Not only can Sun customers create limitless numbers of partitions, they can do so with one image of the operating system.

"IBM's are primarily firmware-based partitions, each of which runs its own copy of an OS," said Gordon Haff, an analyst at Illuminata. "Solaris 10's N1 Grid Containers, on the other hand, are essentially a hardened form of a resource group, many of which run atop a single OS copy."

Sun can offer a cost-savings over IBM, but analysts say the company must show its technology is as reliable as IBM's proven code to be successful.

"Sun clearly has to prove itself," Haff said. "There are potential efficiency advantages (i.e. lower cost), but it's a new and quite different approach."

Marketing term

Another part of the Virtualization Engine plan is IBM's decision to merge its server management products into a single product called IBM Director Multiplatform. Customers will be able use the same software to control IBM and non-IBM gear, clusters and grids. In addition, Unix, Linux and Windows boxes can all be controlled via the same console. HP last year made a similar move, first reported here, with the Systems Insight Manager product.

IBM also plans to include parts of its Tivoli Provisioning Manager software with the Virtualization Engine line. This software controls application provisioning and performance monitoring.

In addition, IBM will ship a package called the Grid Toolbox for Multiplatforms, which is designed to create grid computing systems with hardware from various vendors.

While IBM bills these products as being aimed at all vendors' gear, it does appear to have a preference for certain vendors. Customers will need at least some IBM servers to run the code - as most of it requires AIX - and IBM storage is preferred. The operating systems supported are AIX, SuSE, Red, Windows and Solaris. HP customers be gone.

We'd provide more concrete details, if they were available. At present, IBM has provided no pricing for the Virtualization Engine package. In fact, it will only say the products outline above "may" be part of the total software suite.

IBM garnered a fair amount of press for this announcement, but given these shaky terms, we fear it's still more marketing that actual product. IBM has basically laid out the bits and pieces of its technology arsenal that fall under the virtualization header. ®

    End of another era as former DEC facility faces demolition

    As Intel gets ready to build fabs in Arizona and Ohio, the x86 giant is planning to offload a 149-acre historic research and development site in Massachusetts that was once home to the company's only chip manufacturing plant in New England.

    An Intel spokesperson confirmed on Wednesday to The Register it plans to sell the property. The company expects to transfer the site to a new owner, a real-estate developer, next summer, whereupon it'll be torn down completely.

    The site is located at 75 Reed Rd in Hudson, Massachusetts, between Boston and Worcester. It has been home to more than 800 R&D employees, according to Intel. The spokesperson told us the US giant will move its Hudson employees to a facility it's leasing in Harvard, Massachusetts, about 13 miles away.

  • Start using Modern Auth now for Exchange Online
    Before Microsoft shutters basic logins in a few months

    The US government is pushing federal agencies and private corporations to adopt the Modern Authentication method in Exchange Online before Microsoft starts shutting down Basic Authentication from the first day of October.

    In an advisory [PDF] this week, Uncle Sam's Cybersecurity and Infrastructure Security Agency (CISA) noted that while federal executive civilian branch (FCEB) agencies – which includes such organizations as the Federal Communications Commission, Federal Trade Commission, and such departments as Homeland Security, Justice, Treasury, and State – are required to make the change, all organizations should make the switch from Basic Authentication.

    "Federal agencies should determine their use of Basic Auth and migrate users and applications to Modern Auth," CISA wrote. "After completing the migration to Modern Auth, agencies should block Basic Auth."

  • Arrogant, subtle, entitled: 'Toxic' open source GitHub discussions examined
    Developer interactions sometimes contain their own kind of poison

    Analysis Toxic discussions on open-source GitHub projects tend to involve entitlement, subtle insults, and arrogance, according to an academic study. That contrasts with the toxic behavior – typically bad language, hate speech, and harassment – found on other corners of the web.

    Whether that seems obvious or not, it's an interesting point to consider because, for one thing, it means technical and non-technical methods to detect and curb toxic behavior on one part of the internet may not therefore work well on GitHub, and if you're involved in communities on the code-hosting giant, you may find this research useful in combating trolls and unacceptable conduct.

    It may also mean systems intended to automatically detect and report toxicity in open-source projects, or at least ones on GitHub, may need to be developed specifically for that task due to their unique nature.

  • Why Wi-Fi 6 and 6E will connect factories of the future
    Tech body pushes reliability, cost savings of next-gen wireless comms for IIoT – not a typo

    Wi-Fi 6 and 6E are being promoted as technologies for enabling industrial automation and the Industrial Internet of Things (IIoT) thanks to features that provide more reliable communications and reduced costs compared with wired network alternatives, at least according to the Wireless Broadband Alliance (WBA).

    The WBA’s Wi-Fi 6/6E for IIoT working group, led by Cisco, Deutsche Telekom, and Intel, has pulled together ideas on the future of networked devices in factories and written it all up in a “Wi-Fi 6/6E for Industrial IoT: Enabling Wi-Fi Determinism in an IoT World” manifesto.

    The detailed whitepaper makes the case that wireless communications has become the preferred way to network sensors as part of IIoT deployments because it's faster and cheaper than fiber or copper infrastructure. The alliance is a collection of technology companies and service providers that work together on developing standards, coming up with certifications and guidelines, advocating for stuff that they want, and so on.

  • Infor to stop developing on-prem software for IBM iSeries
    ERP vendor had promised containerized options, but looks set to focus on the cloud

    ERP vendor Infor is to end development of on-premises and containerized versions of its core product for customers running on IBM iSeries mid-range systems.

    Born from a cross-breeding of ERP stalwarts Baan and Lawson, Infor was developing an on-premises containerized version of M3, dubbed CM3, to help ease migration for IBM hardware customers and offer them options other than lifting and shifting to the cloud.

    Infor said it would continue to run the database component on IBM i (Power and I operating system, formerly known as iSeries) while supporting the application component of the product in a Linux or Windows container on Kubernetes.
