Lenovo aims at toppling rivals in the server market

Following its IBM x86 server business acquisition, Lenovo plans on attacking the enterprise hardware arena with low-cost products to undercut the competition.“We can give a better cost solution to enterprise companies,” said Lenovo Executive Vice President Gerry Smith in a press briefing in Beijing Thursday.The Chinese vendor is preparing to offer a wide range of products, targeting markets including supercomputing and hyperscale servers for data centers. “We’re going to play in every segment,” Smith said.Lenovo last year bought IBM’s x86 server business as a way to drive company growth. The deal helped make the Chinese vendor the world’s fourth largest server vendor in this year’s first quarter, with a 7.5 percent share, according to research firm IDC. A year ago, Lenovo had only a 1.1 percent share.To read this article in full or to leave a comment, please click here

Design Considerations for North/South Flows in the Data Center

Traditional data centers have been built by using standard switches and running Spanning Tree (STP). STP blocks redundant links and builds a loop-free tree which is rooted at the STP root. This kind of topology wastes a lot of links which means that there is a decrease in bisectional bandwidth in the network. A traditional design may look like below where the blocking links have been marked with red color.

If we then remove the blocked links, the tree topology becomes very clear and you can see that there is only a single path between the servers. This wastes a lot of bandwidth and does not provide enough bisectional bandwidth. Bisectional bandwidth is the bandwidth that is available from the left half of the network to the right half of the network.

The traffic flow is highlighted below.

Technologies like FabricPath (FP) or TRILL can overcome these limitations by running ISIS and building loop-free topologies but not blocking any links. They can also take advantage of Equal Cost Multi Path (ECMP) paths to provide load sharing without doing any complex VLAN manipulations like with STP. A leaf and spine design is most commonly used to provide for a high amount Continue reading

Cellphone use involved in more than 1 in 4 car crashes

Cellphone-related car crashes were up for the third straight year in the United States and now account for more than one in four crashes, according to the National Safety Council.The nonprofit council created by Congress in 1913, a few years before cellphones came onto the scene, has based its latest report on crash stats from 2013. Its numbers involve crashes involving drivers who are texting or talking on either handheld or hands-free phones.  The Council estimates texting-related crashes rose from 5% to 6% while those involving talking on phones stayed at 21%, for a total of 27% of the 5.7 million crashes in 2013.To read this article in full or to leave a comment, please click here

PQ 50 – Network Service Header (NSH) Deep Dive & Use Cases

On this Packet Pushers Priority Queue episode, we chat with Cisco's Jim Guichard & Paul Quinn about the topic of Network Service Header (NSH). What is NSH meant to be? What might we use NSH for? What will it take to make NSH a widely adopted reality? This is a follow up to Show 238, where Greg was not feeling the NSH magic. The plan was to show Greg the light. Did Jim & Paul succeed?

New ‘Internet of Animals’ actually seems useful for pet owners

And now for something completely different, courtesy of the country that definitely does things differently. Japan is rolling out Anicall (site is in Japanese), a social network for dogs and cats that it refers to as "The Internet of Animals."Anicall first rolled out in January at the first ever Wearable Expo in Japan, but more details were shared on the show "Great Gear" on NHK World, the English-language version of Japan's biggest broadcast network.Anicall works with your smartphone and a plastic collar for the pet. Instead of using GPS and Wi-Fi, the collar uses Bluetooth to communicate, giving it a much longer battery life.To read this article in full or to leave a comment, please click here

Not even an Apple Watch can save shirtless dad bod

Maybe I don't get out enough, but I haven't seen too many Apple Watches in the wild yet. The first 2 I saw belonged to fellow IDG Enterprise editors, who were wielding them at our recent offsite editorial meeting. Both gave "so far, so good" reviews to the devices. The third one I spotted in the wild was at a big concert in Boston this past weekend and the wearer made quite an impression on those in the vicinity. Aside from sunglasses, the only apparel he wore above his waist was the Apple Watch with blue wristband. He was the only shirtless guyI remember seeing at the event, which attracted a mainly college/20-something demographic that I sense this gent was not a member of.To read this article in full or to leave a comment, please click here

How now IoT cow? Sensors can track Elsie’s temperature

The Internet of Things is many things to many people - we’re seeing things like Internet-connected basketballs to vending machines and other devices that connect to the cloud to provide valuable data.One thing I didn’t expect in the IoT world was a device that could measure a cow’s temperature.But that’s exactly what Brad Walters, CEO of Monnit, showed me recently at Interop 2015. Walters’ company makes more than 40 different types of sensors that fit into the world of IoT. Most of the things are dry (or wet) devices that measure temperature, water sensing or gas leaks - important things that can mean the difference between a small problem or a major disaster, whether inside your home or at your remote data center.To read this article in full or to leave a comment, please click here

Review: The New IT

The New IT
Jill Dyche

Research has found that almost half of the CEOs described CIOs as being out of touch with the business and unable to understand how to apply IT in new ways. Over half also considered IT “a commodity service purchased as needed.”

So begins Jill Dyche in her examination of the relationship between IT and business. This statement sums up the entire point of this book: IT needs to find a way to be more engaged in the business world. Rather than just selling IT as a “commodity to be purchased,” IT leaders need to learn to show how IT can drive business value.

The author breaks the topic into three major parts — What’s Wrong with IT, Your IT Transformation Toolkit, and Leadership in the New IT. The first section, of course, outlines the litany of problems with IT in the business world today, from not having a seat at the table to being more about process and tools than actually driving business value. The second section contains a set of exercises that might (or might not — as in my case) apply to you and your role in IT leadership. These exercises involve Continue reading

Server sales bolstered by cloud expansions

Server vendors recorded the strongest shipment growth in over four years for the first quarter, mainly driven by continued investments in the hyperscale server infrastructures that power public and private clouds.It was a great start to the year, with the largest shipment growth since the third quarter of 2010, when the market was recovering from the economic downturn. First-quarter server shipments grew by 13 percent year on year to 2.7 million units, while revenue grew by almost 18 percent to US$13.4 billion, Gartner said on Thursday.This growth was driven by particularly strong demand from the so-called hyperscale area in the U.S. Hyperscale is a term used to describe distributed systems that use thousands of servers to power cloud and big data infrastructures, according to Gartner. Growth came from all form factors, including rack-optimized, blade, density-optimized, and tower servers, according to IDC, which reported similar server numbers on Thursday. Consolidation and virtualization in the enterprise boosted server vendors’ revenue, IDC said.To read this article in full or to leave a comment, please click here

What is OAM – Operation, Administration, Maintenance ?

OAM is a set of tools that have been used to provide network fault indication, performance information, fault localization, data and diagnosis functions. In different standard bodies usage of OAM is slightly different thus it creates a confusion among the engineers. IETF published a best practice RFC to clarify the OAM acronym. RFC 6291 ” Guidelines… Read More »
