Plus kiest communicatieplatform Red Hat en Zarafa

29 maart 2012
By

Leverancier van open source software Red Hat en leverancier van open source groupware en collaboration software Zarafa hebben een gezamenlijke implementatie bij supermarktketen Plus gedaan. Zarafa levert een communicatie- en collaboration-platform dat draait op Red Hat’s besturingssysteem Enterprise Linux 6. De implementatie zal naar verwachting in de eerste helft van 2012 worden afgerond.


Plus heeft 269 winkellocaties in Nederland. De organisatie was op zoek naar een schaalbaar en stabiel collaboration- en communicatieplatform met een hoge beschikbaarheid en functionaliteiten als een agenda, continue toegang tot e-mails via remote access en via mobiele apparaten vanaf elke locatie, synchronisatie van en naar Active Directory, geautomatiseerd gebruikersbeheer en bovenal een systeem waarmee toekomstige uitbreidingen makkelijk te realiseren zijn. Dit was voorheen niet mogelijk vanwege een verouderd systeem dat in 1999 werd genstalleerd en het Outlook-platform dat op fat clients draaide en synchronisatie met mobiele apparaten niet mogelijk maakte.

Besparingen

Zarafa en Red Hat creerden een private cloudarchitectuur waarbinnen een hybride omgeving is gerealiseerd waarin de Zarafa Archiver de kosten van opslagcapaciteit optimaliseert door oude berichten in mailboxen te verplaatsen naar goedkopere opslag.Plus kan hierdoor volgens Zarafa en Red Hat tot wel 40 procent opkostenbesparen. Daarnaast worden door het automatiseren van administration tasks’ driehonderd manuren per jaar bespaard. Nu wordt 0,2 fte genvesteerd in het aanmaken van gebruikers voor supermartktwinkels. Door user generation te automatiseren kan ongeveertwaalfduizend euro per jaar worden bespaard.

Tot slot leveren de setup storage-besparingen met Zarafa Archiver meer dan 10 procent besparing op door oude data op goedkopere opslag en disks te zetten. In de multi tier-storageomgeving van Plus kan de kostenbesparing oplopen tot twintigduizend euro.

Amazon, Eucalyptus team on cloud compatibility

23 maart 2012
By

Amazon has made it pretty clear that it does not believe in private clouds except its own, on which it sells outsiders capacity through its Amazon Web Services. But if companies want private clouds, it has to do something. And that something is to give the nod to Eucalyptus Systems, a maker of a private cloud stack that clones Amazon’s EC2, through a partnership agreement.

Neither AWS nor Eucalyptus Systems, the commercial entity behind the open-core Eucalyptus cloud fabric, gave out much details about the nature of the partnership.

Don’t get too excited about an alliance between the two companies where they would cross-sell each other’s products and services, though. A spokesperson for Eucalyptus told El Reg that the agreement that AWS and Eucalyptus have inked has no such provisions. Rather, the partnership is about making it easier for customers to migrate back and forth between their existing data centers and the EC2 private cloud and its S3 storage service, among other services that AWS offers.

The financial terms of the partnership between the two were not disclosed, and it would be all too easy to be cavalier and guess that Eucalyptus has to shell out some cash to AWS to get its help with ensuring that its management APIs mesh with the ones used by the Eucalyptus fabric.

But it could turn out that with IT suppliers and their end-user companies getting increasingly behind the open source OpenStack cloud fabric that was started by NASA and Rackspace Hosting in July 2010, Amazon needs allies cloning its services on private clouds if it hopes to continue to grow its public cloud business as more and more OpenStack public clouds come to market. Seeing as though AWS and Eucalyptus need each other, it would also be reasonable to guess that no money

EMC-Isilon swallows software storage firm Likewise

21 maart 2012
By

EMC’s Isilon business unit has splashed out and bought a fast-growing startup, Likewise, whose software both EMC and other OEMs and enterprises use to NAS-enable Unix- and Linux-based storage devices.

VC-funded Likewise Storage Services (LSS) says it offers a consistent security model for file-based access and cross-platform, unified storage across physical, virtual and cloud environments. It has integrated identity and access management and secure access to data from Windows, Unix and Linux systems. Supported protocols include SMB/CIFS 1.0, 2.0, 2.1, NFS 3.0 and the RESTful API.

OEMs which use the product include NAS vendors like HP and EMC-Isilon. LSS built on the previous Likewise CIFS platform that has been licensed by EMC-DataDomain, HP, Isilon and others. The LSS product is available through OEMs including EMC-Isilon, HP and Microsoft, or via a commercial licence from Likewise Software.

Microsoft SMB 2.2 support for Linux and Unix is in development. Ken Cheney, Likewise VP for marketing and business development, said: “For many IT organisations, block storage has been the only option for provisioning Microsoft application workloads. Block storage is complex and costly to administer.

“With Windows Server 8, workloads running on Hyper-V, as well Microsoft applications such as IIS and SQL Server, will be able to take advantage of the SMB 2.2 protocol, which aims to provide significant performance, reliability and scalability improvements unattainable with prior versions of SMB. The new SMB 2.2 has the potential to reduce the complexity and costs associated with block storage by enabling both application and user workloads to access file-based storage using NAS devices.”

Other protocols in development include NFS 4.x, pNFS, HTTP/s, and WebDAV.

In December last year, Likewise announced its Data Analytics and Governance software to access, secure, manage and audit unstructured data such as financial files, medical records, office documents, media and big data files across multiple

In December last year, Likewise announced its Data Analytics and Governance software to access, secure, manage and audit unstructured data such as financial files, medical records, office documents, media and big data files across multiple platforms. It integrates with Likewise Storage Services and has adapters that support NetApp, EMC-Celerra and other NAS filers.

Prior to that, in June 2011, the company sold an Active Directory Bridge business unit, which had gained 100,000 users, to BeyondTrust, in order to gain an undisclosed amount of capital to concentrate on the core LSS product area.

Likewise closed a $10m C-round in April 2009, that took total funding to $27m. Let’s imagine the price paid equates to four times total funding price Isilon will have paid around $108m for Likewise.

It must be seeing great potential for expanding sales here or else it sees the technology as absolutely core to its own efforts. The cloud angle is possibly pertinent in this regard. For example, Atmos object storage in the cloud might be NAS-enabled. Possibly there is a NAS + Hadoop play going on as well.

Isilon has secured its own technology and inherited OEM deals with HP, Microsoft and Riverbed, plus partnerships with NetApp and others. The future of those remains to be seen. The new Data Analytics and Governance technology might have relevance to EMC’s initiatives in the GreenPlum and Documentum areas.

The news of the acquisition has been outed by Likewise CEO Barry Crist on the Likewise website. There is nothing on either the EMC or Isilon sites yet; an unexpected display of reticence.

Puppet, hot or not?

Puppet is hot. Ik hoor van veel organisaties dat ze bezig zijn met een implementatie van Puppet of die overwegen. Verschillende van onze klanten zijn bijvoorbeeld bezig met de voorbereiding ervan. Toch is het interessant dat het nu zo populair wordt. Mijn collega’s gebruiken het al jaren voor het beheer van onze systemen. Maar blijkbaar is de tijd er nu ‘rijp’ voor.


Maar wat is Puppet? Het is management software waarmee grote aantallen servers beheerd kunnen worden. Het gaat hierbij zowel om het beheer van configuratie files (zeg maar instellingen van de servers) als het beheer van de genstalleerde software (packages). Een typische use case voor Puppet is bijvoorbeeld het beheer van virtuele servers in een cloud. Het kan dan gebruikt worden om snel extra webservers te installeren. In Puppet worden recepten (classes) gemaakt waarin de server feitelijk beschreven is.

Deze recepten kunnen ook dynamisch zijn doordat ze scripts bevatten die situatie afhankelijk software installeren. Zo kan een script testen op welk type hardware de installatie plaats vindt en aan de hand daarvan bepalen welke specifieke software (t3n behoeve vanILO, DRAC et cetera) genstalleerd moet worden. Op iedere te beheren server draait een server proces (puppet.d) dat met de server communiceert. Deze communicatie is versleuteld en er kan ingesteld worden met welk interval de configuratie van de te beheren server vergeleken wordt met de Puppet server.

Ook kan gebruik gemaakt worden van Facter. Met Facter kan informatie van verschillende servers verzameld worden. Deze informatie kan eventueel samen met variabelen gebruikt worden in de recepten. De recepten zijn overigens te nesten zodat ze hergebruikt kunnen worden. Al met al een krachtig stuk gereedschap dat steeds krachtiger wordt naar mate

ClearStory uncloaks with big data visualization vision

20 maart 2012
By

Yet another big-data company has come out of stealth mode, and this one, called ClearStory Data, has its sights set on making it easier for companies to mash-up and visualize data sets rather than just focusing on data-munching itself.

The founders of ClearStory Sharmila Mulligan, John Cieslewicz, and Vaibhav Nivargi all worked together at Aster Data Systems, the columnar clustered database maker that was acquired by data warehousing pioneer Teradata for $263m a little more than a year ago. They are all well aware of the big data challenges facing companies in terms of the volume and types of data that they want to chew on and mix up to gain insight into their businesses and customers.

But rather than come up with cleverly named Hadoop distribution or yet another kind of data warehouse, ClearStory is taking on the data integration and visualization jobs with its forthcoming ClearStory Data Service. As the name suggests, it will be cloudy and offered as a service.

ClearStory founders John Cieslewicz,

Sharmila Mulligan, and Vaibhav Nivargi

The idea behind the ClearStory Data Service, CEO Mulligan explained to El Reg, is to create what she calls a “self-driven data exploration tool,” something that knows how to integrate with various public data sets such as DataSift, a partner of Twitter’s that gives data analysts access to the full Tweet feed, Microsoft’s Dallas data service for its Azure public clouds, or various government data repositories and that can also be used to merge information with multiple data sets generated by transaction processing and web-log systems.

The problem that ClearStory will attack first is the integration of these disparate data sources. “These services all expose their own data APIs, but they are not for your average user,” says Mulligan.

Each data set has its own

Global server sales shrivel as EMEA leads retreat

16 maart 2012
By

The global server market took a revenue dive in the fourth quarter, with the analysts at IDC figuring that sales revenues sunk 7.2 per cent to $14.2bn, although shipments rose by 2 per cent to 2.2 million units. Europe, the Middle East, and Africa did their part in keeping both sets of numbers down.

IDC did some dicing and slicing of the numbers, and reckons that EMEA server vendors pushed 640,636 pieces of iron out of warehouse loading docks in the final quarter of 2011, a decline of 2.1 per cent compared to the year-ago period. And thanks to a big revenue bump in IBM mainframes in the Q4 2010 and the ongoing decline in the Unix server racket, the comparisons with Q4 2011 were very tough indeed, with revenues down 6.7 per cent to $4.1bn.

Western Europe accounted for just over $2bn in x86-based server sales and just over $1bn in other types of machines. Central Europe, the Middle East, and Africa had $1.05bn in sales across all platform types. Sales in Russia were strong, but collapsed in Poland and the Czech Republic. In the Middle East and Africa, Israel was the only country with server revenue growth, with Saudi Arabia, Turkey, and the United Arab Emirates all down.

It looks like the uptake of density-optimized machines typically installed by hyperscale data centers are finally starting to change the dynamics of the EMEA server business, just as they have in the United States for the past two years.

Shipments of density-optimized machines, which are distinct from rack, blade, and tower machines, and which are being deployed by large web-app operators as well as supercomputing cluster customers (often with GPU coprocessors), shot up by 72.4 per cent to 18,285 units across EMEA, but revenues only grew by 16.6 per cent for these

IBM boasts of Power-AIX win at E-Trade Korea

16 maart 2012
By

Big Blue is bragging once again about its ability to unseat its Unix-racket competitors from customer accounts after a big win at online stock trading company E-Trade Korea.

E-Trade Korea is a big Sparc/Solaris shop, and was established a dozen years ago as a joint venture between the US-based online brokerage of the same name; Japanese telco, finance, and media conglomerate SoftBank; and South Korean LG Investment Securities. In 2008, the online brokerage was acquired by a private-equity group that includes LS Networks, another South Korean conglomerate.

The online brokerage, which is located in Seoul, has 200,000 customers, who use the Sparc/Solaris systems to look at account information, get stock quotes, access bulletin boards, and do other things that online traders like to do. Online trading is big in Korea, with about 40 per cent of the trades done on the Korea Stock Exchange (KSE, established in 1953) and the Korean Securities Dealers Automated Quotations (KOSDAQ, established in 1996) being done by shareholders online.

IBM was not at liberty to disclose how much and what kind of Sun iron was running at E-Trade Korea, but the platforms supporting its trading systems were last upgraded in 2005 and were based on Sun Enterprise machines of various makes and models running the Solaris Unix variant.

Whatever Sun iron was installed at E-Trade Korea, it must have been a lot of machinery, based on what IBM is replacing it with. Sources at IBM tell El Reg that the new E-Trade Korea trading system, which will be installed by July, is comprised of two Power 740s (two-socket machines) two Power 770s (eight-socket machines), and six Power 780s (which come with eight or sixteen sockets, depending on the model).

The new trading platform will run AIX and will be able to settle 970,000 financial transactions per hour

Shuttleworth: Ubuntu rockets up at enterprises

15 maart 2012
By

If data presented in a in a blog post by Ubuntu project founder and “benevolent dictator” Mark Shuttleworth is any indication, then Canonical’s Ubuntu variant of the Debian strain of Linux is waxing on public web services while Red Hat’s Enterprise Linux (RHEL) is waning.

“A remarkable thing happened this year: companies started adopting Ubuntu over RHEL for large-scale enterprise workloads, in droves,” Shuttleworth declared.

The Ubuntu project leader backed up this claim with data gathered by Austrian market researcher W3Techs, which polls the top 1 million Web sites in the world, based on their rankings with Amazon’s Alexa service, and cases the various software technologies powering those sites.

In his blog, he singled out Ubuntu versus RHEL and only for a subset of the data for sites using Linux on some aspect of their public web sites. Many Web sites have multiple operating systems running across their web infrastructure, so the percentages add up to more than 100 per cent. Here’s the trend lines for Ubuntu and RHEL over the past year. And yes, it was silly to have RHEL in black and Ubuntu in red, but there you have it:

Ubuntu on the rise, RHEL slipping a bit (click to enlarge)

“The trend is even starker if you look at what we know of new-style services, like clouds and big data, but since most of that happens behind the firewall it’s all anecdata [sic], while web services are a public affair,” Shuttleworth continued.

But don’t get the wrong idea. The web is not just about Ubuntu versus RHEL. Hardly, in fact.

W3Techs shakes out redirects like www.sun.com now jumping to www.oracle.com. So the number of sites in the data is actually a little lower than 1 million. And across those sites, Ubuntu distributions were in use on a

Oracle revs home-tweaked Linux kernel to 2.0

13 maart 2012
By

Software giant Oracle has gussied up the second iteration of its own kernel for Ellison’s Enterprise Linux distro, dissing Red Hat’s own tweak on the mainstream Linux 3.0 kernel.

Back in October 2011, Edward Screven, chief corporate architect at Oracle and the person responsible for the company’s Linux operating system and Xen hypervisor variants, gave a preview of the Unbreakable Enterprise Kernel Release 2, and today’s release makes good on all the promises.

As with the kernels embedded in the latest Red Hat and SUSE Linux releases, the Enterprise Kernel R2 from Oracle moves up to the Linux 3.0 version, which is not a huge generational shift like the name might imply but rather more a function of Linus Torvalds, the creator and maintainer of the Linux kernel, getting bored with saying Linux 2.6.3X.

That said, the new Oracle kernel has plenty of new features that warrant a look-see and perhaps an install if you are running Oracle Enterprise Linux 5 or 6. The new kernel, as you can see from the release notes, is not just supported on Oracle Linux 6, but has been backported to Oracle Linux 5.

Oracle Linux is, of course, a clone of Red Hat’s Enterprise Linux, but one in which Oracle creates its own rev of the open source Linux kernel and then tweaks and supports for its server customers. Oracle Linux is at the heart of its Exadata, Exalogic, Exalytics, and Big Data Appliance x86-based machines for database, Web application, analytics, and MapReduce workloads.

Oracle Linux is backed up by what the company calls Unbreakable Linux support and is offered with Oracle’s own kernel, tuned for specific workloads on Oracle’s engineered systems – as well as available to run on other popular machinery.

Unbreakable Enterprise Kernel R2 is based on the open source Linux
