Mellanox Trims Down To Reach For A Profitable $1 Billion

If Mellanox Technologies had not begun investing in the Ethernet switching as it came out of the Great Recession, it would be a much different company than it is today. It might have even been long since acquired by Oracle or some other company, for instance.

To be sure, Mellanox might have been able to capture some business at the cloud builders, hyperscalers, and clustered storage makers with InfiniBand. But it would not have been the one to capitalize on moving InfiniBand-style technologies such as remote direct memory access (RDMA) to Ethernet, and it would not have been able to …

Flattening Networks – And Budgets – With 400G Ethernet

If it were not for the insatiable bandwidth needs of the twenty major hyperscalers and cloud builders, it is safe to say that the innovation necessary to get Ethernet switching and routing up to 200 Gb/sec or 400 Gb/sec might not have been done at the fast pace that the industry as been able to pull off.

Knowing that there are 100 million ports of switching up for grabs among these companies from 2017 through 2021 – worth tens of billions of dollars per year in revenues – is a strong motivator to get clever.

And that is precisely what …

IBM Gets Machines Back Into International Business

Designing and manufacturing processors – or paying a third party foundry to do some of the work – and then manufacturing systems and updating and modernizing operating systems and middleware is tough work. And it is work that few IT vendors and about the same number of hyperscalers do these days. Despite all of the gut-wrenching changes in the datacenter over the past six decades, International Business Machines is still in the game that it largely defined so long ago.

In the fourth quarter of 2017, the company’s System z mainframes had the highest shipment level, as gauged by aggregate …

Datacenters Brace For Spectre And Meltdown Impact

The Spectre and Meltdown speculative execution security vulnerabilities fall into the category of “low probability, but very high impact” potential exploits. The holes that Spectre and Meltdown open up into systems might enable any application to read the data of any other app, when running on the same server in the same pool of system memory – bypassing any and all security permissions. These potential exploits apply to every IT shop, from single-tenant servers potentially exposed to malware to apps running in a virtual machine (VM) framework in an enterprise datacenter to apps running in a multi-tenant public cloud instance. …

NOAA Weather Forecasts Stick With CPUs, Keep An Eye On GPUs

When it comes to supercomputing, more is almost always better. More data and more compute – and more bandwidth to link the two – almost always result in a better set of models, whether they are descriptive or predictive. This has certainly been the case in weather forecasting, where the appetite for capacity to support more complex models of the atmosphere and the oceans and the integration of models running across different (and always increasing) resolutions never abates.

This is certainly the case with the National Oceanic and Atmospheric Administration, which does weather and climate forecasting on a regional, national, …

Quantum Computing Enters 2018 Like It Is 1968

The quantum computing competitive landscape continues to heat up in early 2018. But today’s quantum computing landscape looks a lot like the semiconductor landscape 50 years ago.

The silicon-based integrated circuit (IC) entered its “medium-scale” integration phase in 1968. Transistor counts ballooned from ten transistors on a chip to hundreds of transistors on a chip within a few short years. After a while, there were thousands of transistors on a chip, then tens of thousands, and now we have, fifty years later, tens of billions.

Quantum computing is a practical application of quantum physics using individual subatomic particles chilled to …

The Spectre And Meltdown Server Tax Bill

The new year in the IT sector got off to a roaring start with the revelation of the Meltdown and Spectre security threats, the latter of which affects most of the processors used in consumer and commercial computing gear made on the last decade or so.

Much has been written about the nature of the Meltdown and Spectre threats, which leverage the speculative execution features of modern processors to give user-level applications access to operating system kernel memory, which is a very big problem. Chip suppliers and operating system and hypervisor makers have known about these exploits since last June, …

NVLink Shines On Power9 For AI And HPC Tests

The differences between peak theoretical computing capacity of a system and the actual performance it delivers can be stark. This is the case with any symmetric or asymmetric processing complex, where the interconnect and the method of dispatching work across the computing elements is crucial, and in modern hybrid systems that might tightly couple CPUs, GPUs, FPGAs, and memory class storage on various interconnects, the links could end up being as important as the compute.

As we have discussed previously, IBM’s new “Witherspoon” AC922 hybrid system, which was launched recently and which starts shipping next week, is designed from …

Two Hyperscalers Down For AMD’s Epyc, Six To Go

You can’t call them the Super 8 because the discount hotel chain already has that name. But that is what they – with the they being Google, Amazon, Microsoft, and Facebook in the United States and Baidu, Alibaba, Tencent, and China Mobile in China – are. They are the biggest spenders, the hardest negotiators, and the most demanding customers in the IT sector.

Any component supplier that gets them buying their stuff gets kudos for their design wins and is assured, at least for a generation of products, a very steady and large demand, even if they might not bring …

Building An Enterprise Blockchain

The word has come down from the top: Your company is going blockchain, and you will be implementing it. You have heard the buzz and are aware there is a difference between blockchain – the distributed, peer-to-peer ledger system – and its digital currency cousin, Bitcoin, which has been in the headlines. But how do you build an enterprise-class blockchain?

Let’s start with the basic premise, as that will inform the architectural and technical choices you make. Organizations are jumping on the blockchain bandwagon as a means of making transactions that span multiple parties simpler, more efficient and available at …

Battle For Datacenter Compute: Qualcomm Centriq Versus Intel Xeon

Putting more and more cores on a single CPU and then having two CPUs in a standard workhorse server is something that yields the best price/performance for certain kinds of compute-hungry workloads, and these days, particularly those who want top bin Xeon parts and the cost of the processor is no object because it saves on the total number of server nodes that has to be deployed.

But this is not the only way to pack the most compute density into a rack. A case can be made for middle bin parts, particularly for workloads that scale well across many …

Renting The Cleanest HPC On Earth

One of the most interesting and strategically located datacenters in the world has taken a shining to HPC, and not just because it is a great business opportunity. Rather, Verne Global is firing up an HPC system rental service in its Icelandic datacenter because its commercial customers are looking for supercomputer-style systems that they can rent rather than buy to augment their existing HPC jobs.

Verne Global, which took over a former NATO airbase and an Allied strategic forces command center outside of Keflavik, Iceland back in 2012 and converted it into a super-secure datacenter, is this week taking the …

Deep Dive Into Qualcomm’s Centriq Arm Server Ecosystem

Qualcomm launched its Centriq server system-on-chip (SoC) a few weeks ago. The event filled in Centriq’s tech specs and pricing, and disclosed a wide range of ecosystem partners and customers. I wrote about Samsung’s process and customer testimonials for Centriq elsewhere.

Although Qualcomm was launching its Centriq 2400 processor, instead of focusing on a bunch of reference design driven hardware partners, Qualcomm chose to focus its Centriq launch event on ecosystem development, with a strong emphasis on software workloads and partnerships. Because so much of today’s cloud workload mix is based on runtime environments – using containers, interpretive languages, …

Power9 To The People

The server race is really afoot now that IBM has finally gotten off the starting blocks with its first Power9 system, based on its “Nimbus” variant of that processor and turbocharged with the latest “Volta” Tesla GPU accelerators from Nvidia and EDR InfiniBand networks from Mellanox Technologies.

The machine launched today, known variously as by the code-name “Witherspoon” or “Newell,” is the building block of the CORAL systems being deployed by the US Department of Energy – “Summit” at Oak Ridge National Laboratory and “Sierra” at Lawrence Livermore National Laboratory. But more importantly, the Witherspoon system represents a new …

Disaggregated Or Hyperconverged, What Storage Will Win The Enterprise?

It has been a long time coming, but hyperconverged storage pioneer Nutanix is finally letting go of hardware, shifting from being an a server-storage hybrid appliance maker to a company that sells software that provides hyperconverged functionality on whatever hardware large enterprises typically buy.

The move away from selling appliances was something that The Next Platform has been encouraging Nutanix to do to broaden its market appeal, but until the company reached a certain level of demand from customers, Nutanix had to restrict its hardware support matrix so it could affordably put a server-storage stack in the field and not …

The Booming Server Market In The Wake Of Skylake

The slowdown in server sales ahead of Intel’s July launch of the “Skylake” Xeon SP was real, and if the figures from the third quarter of this year are any guide, then it looks like that slump is over. Plenty of customers wanted the shiny new Skylake gear, and we think a fair number of them also wanted to buy older-generation “Broadwell” Xeons and the “Grantley” server platform given the premium that Intel is charging for Skylake processors and their “Purley” platform.

Server makers with older Broadwell machinery in the barn were no doubt happy to oblige customers and clear …

Generally speaking, the world’s largest chip makers have been pretty secretive about the giant supercomputers they use to design and test their devices, although occasionally, Intel and AMD have provided some insight into their clusters.

We have no idea what kind of resources Nvidia has for its EDA systems – we are trying to get some insight into that – but we do know that it has just upgraded a very powerful supercomputer to advance the state of the art in artificial intelligence that is also doing double duty on some aspects of its chip design business.

The Redemption Of NFS

If thinking of NFS v4 puts a bad taste in your mouth, you are not alone. Or wrong. NFS v4.0 and v4.1 have had some valid, well-documented growing pains that include limited bandwidth and scalability. These issues were a result of a failure to properly address performance issues in the v4.0 release.

File systems are the framework upon which the entire house is built, so these performance issues were not trivial problems for us in IT. Thanks to the dedication of the NFS developer community, NFS v4.2 solves the problems of v4.0 and v4.1 and also introduces a host of …

The Battle Of The InfiniBands

When it comes to HPC, compute is like the singers in a rock band, making all of the noise and soaking up most of the attention. But the network that lashes the compute together is literally the beat of the drums and the thump of the bass that keeps everything in synch and allows for the harmonies of the singers to come together at all.

In this analogy, it is not clear what HPC storage is. It might be the van that moves the instruments from town to town, plus the roadies who live in the van that set up …

The Ecosystem Expands For AMD Epyc Servers

The “Naples” Epyc server processors do not exactly present a new architecture from a new processor maker, but given the difficulties that AMD had at the tail end of the Opteron line a decade ago and its long dormancy in the server space, it is almost like AMD had to start back at the beginning to gain the trust of potential server buyers.
