IBM has announced a brand new top-of-the-line DS8870 storage equipment which the enterprise says performs three times quicker than the outdated desirable performer in its DS8000 storage household. along with the brand new DS8870, IBM has announced plenty of new applied sciences to improve security, take skills of cloud computing, and manage massive datasets.
IBM Power7+ Processor
IBM’s new choices encompass vigor 770 and energy 780 servers that includes the POWER7+ microprocessor. in line with IBM, POWER7+ provides a performance enhance of as much as forty % on Java workloads and as plenty as 30 percent with OLTP and ERP environments compared to the general POWER7. POWER7+ additionally expands the POWER7’s L3 cache through 2.5x and keeps the same energy usage as POWER7 processors.
The IBM gadget Storage DS8870 is the most up-to-date member of the DS8000 family of excessive-density business storage systems. With superior POWER7 processors and up to 1TB of device cache, the DS8870 promises as much as thrice more performance for transaction processing functions than the DS8800. The DS8870 has completed the maximum ranking within the Storage performance Council’s SPC-2 benchmark.

you possibly can should search excessive and low, throughout time and lower back again, to find a extra pure software equipment than the software device/four hundred and its forebears in the device/3X line and its great-grandchild, the vigour techniques platform working IBM i. but oddly ample, as IBM introduced the power edition of its PureApplication converged methods ultimate week, the one thing it did not do is announce a variant of the stack that may help the IBM i working equipment.
it's like blade servers in every single place once again, with OS/four hundred getting such late and kludge aid that the one client set that might naturally pay a top rate for the combination merits of a BladeCenter chassis aiding a mix of energy and X86 blade servers and built-in management have been alienated from the market after which invited late to the celebration. You doubtless understand what i'm thinking that big Blue need to do earlier than I even write this story. but let’s go through it simply to get the considering obviously outlined and on paper. neatly, pixels.
First things first. there's nothing incorrect with the brand new PureApplication W1700 hardware and software stack introduced on February 12 when you are an AIX customer operating the DB2 database. Or an Oracle or Hewlett-Pakard shop eager to flow off their respective Sparc/Solaris or Itanium/HP-UX platforms. and even Wintel and Lintel shops wanting to flow up or over (depending on how you view the relative platforms) to vigor-AIX. the rest that makes vigor more suitable makes IBM i are living longer.
the new PureSystems W1700 appliances are similar to the Xeon E5-based W1500 home equipment that IBM announced again in April 2012 when the Flex device modular servers, which merge servers, networks, and storage right into a blade-like and rack-like hybrid. The change is that the W1500 appliances are in response to two-socket, half-width Flex x240 server nodes that use Intel Xeon E5 processors and, at the least in response to the inner IBM documentation I actually have viewed, the W1700 is based on a 4-socket, full-width server node it's based on the Power7+ processor from IBM.
but wait, you say? IBM has now not announced a four-socket Power7+ server node for the Flex system chassis. appropriate. no longer as a standalone product, and not in anything that you may study concerning the W1700 appliances in announcement letter 213-091 or on IBM’s internet web page. And let me say some thing right here in regards to the first rate americans of software group, which might be managing the PureSystems launches. facts sheets are presupposed to have information in them. Feeds, speeds, slots, and watts. this is a hardware and a gadget announcement in spite of everything. americans need to be aware of what the server node is, what switches you are the usage of to link them together, how the storage is integrated, and all of the facets within the rack that contain the PureApplication system. announcing it has this many cores, that a whole lot reminiscence and disk, and not giving a price is not adequate.
What i do know for bound about the hardware within the new W1700 stacks is that Steve Sibley, director of international product administration for IBM’s vigor programs division, told me all through a Power7+ briefing relating to the vigor programs iron two weeks in the past that huge Blue changed into expecting the Power7+ processor to launch the vigor-based mostly variant of the PureApplication stacks as opposed to do a Power7 edition ultimate 12 months. This probably has to do with the performance, extra cache memory on chip, and elevated leading memory (both actual and thru lots-better reminiscence compression, which now has its algorithms achieved on special accelerators on the Power7+ chips as opposed to with the aid of the CPUs) that the Power7+ chips present. This stands to motive, of route. in addition, IBM needed to lead towards Oracle’s Exadata database clusters and Exalogic middleware clusters, which can be in response to Xeons, with its own Xeon iron. Or at least somebody believed that. If energy is so a whole lot more advantageous, and if I were IBM, i might all the time lead with energy and have X86 iron as an option.
Anyway, the announcement letter tells you the way a great deal a W1700 equipment weighs and the way loud it is, however it doesn’t let you know what the processor nodes are, what number of cores are on the processor, how a lot leading reminiscence can also be added to the node, and it says nothing concerning the networking that links nodes to storage. One document I even have considered confirms that it's a full-width node, and that skill it is a four-socket field and it just about actually has to be the impending Flex p460+ server node I predict any day now as a standalone product. The setups include from 96 to 608 cores, with reminiscence scaling together with cores. The machines have built-in arrays with a group mixture of flash and disk that has data insurance policy across assorted RAID units (with spare drives) so that you can improve from storage error. again, the documents don’t say precisely what variety of RAID, and incidentally, it concerns what form for each efficiency and availability reasons. Anyway, the equipment has arrays with 48 TB of disk and 6.4 TB of flash storage, presumably with hierarchical storage administration. (again, IBM doesn’t say and it will.) listed below are their 4 sizes, and the fees of the thoroughly configured W1700 software appliances:
The techniques run AIX 7.1 and can't be deployed with Linux or IBM i, however technically there is not any reason behind it. The machinery is licensed to place the PowerVM hypervisor on each node if you need, and you'll also put DB2 commercial enterprise Server version 9.7 on the entire nodes. Ditto for the V7.0, V8.0, and V8.5 versions of WebSphere application Server Hypervisor version.
i used to be guessing that the small configuration is 4 four-socket p460+ server nodes the usage of six-core Power7+ chips, after which medium doubles it up, and large doubles it once again. The exact-end computer has to be the use of eight-core Power7+ chips for the numbers to work, and it has to have 19 server nodes for the processor core count to work. this is just a bet within the absence of statistics. An IBM spokesman told me that the W1700s use eight-core Power7+ processors working at three.61GHz. here's the midrange half within the p260+ node introduced closing November, incidentally, and to get the core counts to work, you might have six half-width nodes in its place of four full-width nodes the use of six-core chips to get there. IBM may even be deactivating cores to have them as skill on demand. once again, IBM became no longer clear.
The W1700 machines above may additionally sound pricey, but bear in mind that an Exadata X2-2 database cluster would cost $4.47 million at list expense with 96 cores. (I don’t have Exadata X2-3 pricing convenient.) None of these machines are low-budget, and as a lot as IBM talks about it, they aren't really aimed toward small corporations and even most midrange stores. identical to Exadatas are not. The PureApplications latitude in price from $30,938 to $27,911 per core, utterly careworn, if you do the math. that's less high priced per core than purchasing simply AIX plus DB2 or simply IBM i (which includes DB2 for i) for a huge bad vigor 780 or 795 SMP equipment–devoid of the fee of the iron even accounted for in the SMP machines. So the message is obvious, and one that Oracle has been hammering on for years: if you can run your apps on a virtualized cluster as an alternative of on a big SMP laptop, you should definitely.
I even have been saying this so lengthy that i'm blue within the face, however i'll say it again. IBM must create a child PureApplication gadget that runs IBM i and makes use of the DB2 Multisystem clustering that has been around continually to attach together nodes into a single database picture as the PureScale extensions to DB2 and AIX do in the PureData transaction processing home equipment. And IBM should also make these beefier PureApplication techniques purchasable working IBM i with the identical relative pricing to huge SMP boxes that AIX/DB2. Any method it is decent to are trying to steal Oracle and HP consumers and develop the AIX/DB2 base is also good to keep and growth the current IBM i base.
The ordinary knowledge is that it takes 10 times as a great deal money and effort to profit one consumer than it does to preserve one. We’re down anything on the order of 125,000 valued clientele–virtually half of the top OS/400 base in 1999. conserving the one hundred fifty,000 we've happy, and giving IBM i stores all of the identical candies and advantages, won’t make headlines like taking on Oracle. however it bound would make the lives of Oracle, HP, Dell, and now Cisco systems a hell of lots more durable after they are attempting to poach IBM i shops.

At the end of July, Oak Ridge National Laboratories started receiving the first racks of servers that will eventually be expanded to become the “Summit” supercomputer, the long-awaited replacement to the “Titan” hybrid CPU-GPU system that was built by Cray and installed back in the fall of 2012. So, technically speaking, IBM has begun shipping its Power9-based “Witherspoon” system, the kicker to the Power8-based “Minksy” machine that Big Blue unveiled in September 2016 as a precursor and a testbed for the Power9 iron.
Given that IBM is shipping Summit nodes to Oak Ridge and has also started shipping similar (but different) nodes to Lawrence Livermore National Laboratory for the companion “Sierra” supercomputer, we would have expected some sort of announcement of Power9 servers by now. Such an announcement hasn’t happened, but we are hearing rumblings that announcements could be imminent, perhaps in late September or sometime in October.
With Intel getting its “Skylake” Xeon SP processors out the door formally in July but shipping them since late last year, and AMD pushing both its “Naples” Epyc X86 server processors and companion Radeon Instinct GPU accelerators in a one-two punch that Intel cannot do, it would be good for IBM’s Cognitive Systems business for the Power9 systems to launch sooner rather than later. We know for sure that Power9 systems supporting IBM’s own AIX Unix and IBM i (formerly OS/400) proprietary OS/database platform will not be coming until early 2018, maybe March or April. But that does not mean IBM can’t launch Linux-only Power9 systems, most likely aimed at the lucrative HPC and AI markets, before the end of the year.
There are two flavors of Power9 chips, the “Nimbus” Power9 scale out processor for machines with one and two sockets and the “Cumulus” Power9 scale up processor for machines with four, eight, or sixteen sockets. We detailed all of the feeds and speeds, and the underlying architecture of the Power9 chips, back in August 2016, and we talked about how the hybrid approach embodied in Power9 would bring competition to datacenter compute and, more specifically, how NVLink and OpenCAPI (which are very closely related) and coherency across CPUs and GPUs inside of nodes would be transformative. While the Minsky servers had native NVLink 1.0 ports, which ran at 16 Gb/sec per lane, this coherency support was not ready for the Power8+ chips (we know IBM doesn’t call it that, but that is what it is) and the NVLink 2.0 ports will run at the much faster 25 Gb/sec signaling per lane and will support hardware-assisted coherency across the memory spaces between the Power9 chip and the Volta (and maybe the Pascal) GPU accelerators. This coherency is a key part of IBM’s computing strategy, and support for it is in the early stages for Linux right now and will be more generally available early in 2018, as IBM explained to us at the ISC17 supercomputing event.
IBM has said since the middle of 2016, when it unfolded Power chip roadmaps out past 2020, that we should expect Power9 systems to ship in the second half of this year, and the presumption was not just for the Summit and Sierra machines, which are being paid for by the US Department of Energy, to get them, but for other organizations that want to deploy Power9 CPUs tightly coupled to Nvidia Tesla V100 GPU coprocessors through the NVLink interconnect, to also have them. This tight coupling is not possible with Intel Xeon or AMD Epyc processors because, thus far, neither has native NVLink ports on the CPU like the Power9 chip does.
IBM has a bunch of different machines using the Power8 and Power8+ processors, and we suspect that Big Blue and its motherboard and system partners, including a number of members of the OpenPower consortium, will have a slew of machines tricked out for the Power9 chips, too. IBM will no doubt roll out a bunch of Power9 machinery over the course of 2018, and possibly starting here in late 2017, but the exact feeds and speeds of this iron and the timing of its delivery under the Cognitive Systems brand (formerly known as Power Systems) has not yet been revealed. We are hearing things, however.
The Minksy system, which was also was known under the code-name of “Garrison” when it was being developed, is sold as the Power S822LC for HPC by IBM and is actually made by Wistron, one of the big ODMs, and rebadged and resold by Big Blue. It has two Power8+ chips, with two NVLink 1.0 ports and four “Pascal” Tesla P100 accelerators in the SXM2 form factor mounted on the motherboard. Two of the Pascals link directly to each Power8+ chip through NVLink ports, and then the remaining NVLink ports are used to cross couple the GPUs in the system so they can share data at 80 GB/sec rates. This design, like a few other Power8 systems from the OpenPower camp, put main memory on a riser card and the “Centaur” memory buffer chip and its integrated L4 cache memory onto that riser rather than on the memory DIMMs themselves, as IBM does for its own designs.
Spiritually, it looks like the Minsky/Garrison system is more linked to Sierra than to Summit. Lawrence Livermore has been less vocal about its Power9 server deliveries, but sources at the lab tell The Next Platform that it has received its first machines and that they do, as rumors have suggested, pair two Power9 processors with four Volta accelerators in each node. Lawrence Livermore has been quiet about the precise feeds and speeds of the machine, but has said that Sierra will deliver somewhere around 120 petaflops to 150 petaflops with total memory on the order of 2 PB to 2.4 PB and at around 11 megawatts of power consumption. That makes it about five times as energy efficient as the “Sequoia” BlueGene/Q system it replaces to help steward the nuclear weapons stockpile of the United States, with 5X to 7X the application performance of Sequoia. At 7.5 teraflops at double precision for each Volta coprocessor, and assuming that the Power9 chip has negligible math skills compared to the GPUs, that works out to 4,000 to 5,000 nodes for Sierra, and that also works out to a clean 512 GB of main memory per node if you do the math.
That memory capacity does not include the 16 GB of HBM2 memory on each Volta coprocessor. That HBM2 memory, which has a bandwidth of 900 GB/sec, is as far as applications are concerned, the important thing. Programmatically speaking, that main memory on the Power9 processor is more like a L3 cache for the GPU, once the coherency is turned on, and all of the other caches in the Power9 complex, including the L4 cache in the Centaur buffer chips, are really just staging for the GPUs except for the parts where they are doing serial work in C or Fortran.
As we have previously reported, the Summit supercomputer at Oak Ridge will pair two Power9 chips with six Volta GPU accelerators. Oak Ridge said that it would build Summit from around 4,600 nodes, up a bit from its previous estimate a few years back, and that each node would have 512 GB of main memory and 800 GB of flash memory. That’s 2.24 PB of main memory, 3.5 PB of flash memory, and nearly 72 GB of HBM2 memory across the cluster, which will be linked with 100 Gb/sec EDR InfiniBand. (The 200 Gb/sec HDR InfiniBand from Mellanox Technologies was not quite ready in time for the initial installations in July.) Those extra GPUs push the power envelope of the Summit machine up to around 13 megawatts, and they should deliver around 207 petaflops of peak theoretical performance (absent the Power9 floating point) at double precision. Oak Ridge had been planning for around 40 petaflops of performance per node, and it looks like it is getting 45 petaflops.
What we are hearing on the street is that IBM’s Witherspoon kicker to the Minksy/Garrison system will support either four or six Volta GPU accelerators and is being used in both the Summit and Sierra boxes, which makes sense if you want to amortize the $325 million cost of the two systems across a single architecture. If this is true, that means, in theory, that Lawrence Livermore will be able to boost its per node performance by 33 percent just by adding GPU accelerators to empty slots.
If we had to guess, we would say that IBM will use a consistent naming convention, and replace the 8s in the Power Systems line with 9s in the Cognitive Systems line, and so this machine should be called the Cognitive Systems 922LC for HPC. And we are willing to bet that this will be the first machine IBM formally launches for other customers, and it will probably be sooner rather than later. It cannot let Intel and AMD breathe up all the processor oxygen, and it has to lay the groundwork for the Power9 rollout that will no doubt happen throughout 2018, including servers aimed at its core enterprise customers. This naming, and the very nature of the IBM product line, implied the Cognitive Systems S914, S922, S924 with some L and LC variants and the Cognitive Systems E850C, E870C, and E880C.
We expect that the Cognitive Systems 922LC for HPC will employ a chip with high core count and low threading, and make use of industry standard memory with no Centaur buffer chips to reduce cost. The Power9 chip is designed with 24 cores, and it will depend on yields at Globalfoundries using its 14 nanometer processes to see if the Summit and Sierra nodes, as well as the ones sold to others, get 20, 22, or 24 cores with SMT4 threading. This machine will no doubt come with a water cooled option, as did the Minksky/Garrison box, and it will be a Linux only machine with the open OPAL microcode that has been created under the auspices of the OpenPower consortium with search engine giant Google. We have a strong suspicion that the InfiniBand networking in this system will be a snapable mezzanine card, allowing for the two labs and any other customer using this machine to upgrade the network without having to change the servers; this mezzanine card approach is becoming more common in systems for this very reason.
We suspect that there will be other variants of the entry Cognitive Systems line that have one or two sockets and that may or may not include the SXM2 socket for Volta GPU coprocessors. We suspect that the other members of the future Cognitive Systems line will use the PCI-Express versions of the Volta accelerators and have expansion for other kinds of PCI-Express cards and even NVM-Express storage, which is becoming increasingly important in the datacenter. IBM is first out the door among its server peers to support the PCI-Express 4.0 protocol, has twice the bandwidth of PCI-Express 3.0 and delivers a total bandwidth of 64 GB/sec across a sixteen lane adapter slot. We are curious, too, if IBM is going to be reselling the “Zaius” motherboard created by Google and Rackspace Hosting, and if Supermicro is going to be revamping with follow-ups to the “Briggs” and “Stratton” systems it launched with Power8 chips last year.
The past rollouts of the Power7, Power7+, and Power8 systems are not necessarily an indicator of how IBM will roll out the Power9 systems. But in general, IBM does not launch all of its machines at once and there is no reason to believe it will do so this time. Sometimes, as with the Power7, it starts in the middle and then works its way down the line and then up the line. Power8 started with entry machines, then big NUMA boxes, and then the midrange. A lot will depend on where IBM thinks demand is, and what yields Globalfoundries gets on the Power9 Nimbus and Cumulus chips.
The good news is that IBM can tune a chip to have 24 cores with SMT4 threading (four threads per core) or 12 cores with SMT8 threading (eight threads per core) pretty much on the fly, and so it can balance between threading and core count as needed. The SMT4 cores are aimed at Linux workloads, and the SMT8 cores are aimed mostly at AIX and IBM i. It can also dial in buffered or unbuffered memory, with different bandwidths and capacities, as needed across these two different kinds of platforms.

Do you remember the Flex System modular servers launched seven years ago this month? These were the innovative machines that Big Blue sold off to Lenovo about two and a half years after they were launched and they were ramping? Do you remember the PurePower follow-ons to these that came out in May 2015? Or did we all just imagine that happened?
These modular machines, which were somewhere halfway between a rack server and a blade server, were put into preconfigured stacks and as the PureFlex system had cloud automation software to create a private cloud and then had PureApplication variants that took it one step further, creating scripting tools DevOps-style, called patterns, to automate the provisioning of virtual compute, storage, and networking for and the automagic deployment of applications. After the System x division was sold to Lenovo in early 2015 and IBM wanted to focus on its Power-based iron, it created a similar stack of hardware and software – what is variously called converged systems or integrated systems – called PurePower and based on Power S822 and Power S822L nodes using (as the names suggest) Power9 processors. In October of that year, IBM i was added as a supported operating system on the Power S822 nodes in the PurePower clusters, allowing for a private cloud to provision IBM i, AIX, and Linux on the same hardware substrate.
An announcement from IBM last week got me to thinking about all PurePower and predecessor effort to create a converged platform to peddle into the heterogeneous datacenters of the world. This particular announcement was not of huge consequence. In announcement letter 219-217, IBM promised that it would be updating the PureApplication W3500 and W3550 appliances, which are Xeon-based clusters to run the full-on PureApplication stack. IBM also said that it would allow the PureApplication automated systems to be able to deploy Red Hat OpenShift, its Kubernetes environment for Docker containers, as a pattern, and ditto for IBM’s homegrown Cloud Automation Manager Kubernetes/Docker stack.
The PureApplication W3700 appliances, which were based on Power7+ iron, have not been upgraded to Power8 or Power9 servers as far as we know, and presumably the PurePower cluster based on plain vanilla Power Systems rack servers has replaced them. As far as we can tell from IBM’s sales manual and announcement letters, these PurePower clusters have not been updated to Power9 iron, either. But with Red Hat being acquired by IBM for $34 billion, we could see a kind of stackable, rackable Power-Linux superstructure offering in the not too distant future, and one we hope that treats IBM i as a peer to Linux.
We spend a lot of time thinking about how to make the Power Systems business stronger, and there are two approaches and both are reasonable. One is to take a single Power server and run IBM i on the core partitions and then bring in Linux infrastructure workloads that replace Windows Server functions in the datacenter. The other is to create a hybrid rack that includes Power nodes and X86 nodes – and Arm nodes if there is a call for them – and put them all under the same management domain and literally run IBM i, AIX, Linux, and Windows Server on the machines that are best suited to the task. IBM tried this with BladeCenter blade servers starting in 2001 and again with the Flex System iron again in 2012. There were some successes in hybrid systems, and certainly some capital expense and operational expense saving on these converged platforms. But it is not like they took the market by storm.
The acquisition of Red Hat gives IBM a very good chance to start replacing Windows Server and bringing all kinds of applications onto Linux running natively on Power.
Certainly all of the major open source projects relating to data analytics and machine learning frameworks in the world are designed for Linux, and IBM can do a better job leveraging this by expanding the Red Hat portfolio to include all kinds of things, including Hadoop, Spark, Redis, Cassandra, and a litany of software all supported by IBM through the expanded Red Hat organization. Every important database and datastore – MySQL and MariaDB for straight up SQL serving; TimescaleDB and InfluxDB for time series databases; MongoDB and Couchbase for document databases; Tigergraph, GraphDB, and Neo4j for graph databases; and funky stuff like CockroachDB (inspired by Google Spanner) and FaunaDB (inspired by Twitter) that are distributed databases that are made to scale across multiple geographies. The point is, you can support Oracle. Db2, and Db2 for i for traditional transaction processing, but you need all this other stuff to help the Power Systems business grow. Anything that makes Power Systems stronger makes IBM i last longer, and these should all be supported atop RHEL and, I think, turned into distributions that are supported by the combined Red Hat/IBM organization.
IBM needs to be thinking on a much larger scale than Linux operating systems, JBoss middleware, and Kubernetes/Docker container infrastructure. The beauty is that all of these projects are open source, and any of them can offer an alternative provider of tech support. Or have their teams acquired to build out the software portfolio. Why not? IBM is not going to be able to sell mainframe middleware forever. IBM i might last forever, but it cannot alone support the investments required to create a Power processor and server platform. But the revenue streams from all of these kinds of projects, with the Big Blue and Red Hat dynamic duo, could make IBM formidable in open systems on OpenPower.
Stranger things have happened. Like IBM buying Red Hat, for instance.RELATED STORIES

The once ubiquitous 3.5mm headphone jack is quickly becoming a rarity in the consumer smartphone industry. Apple nixed the standard from the iPhone 7 and up, while the majority of Android manufacturers have followed suit. Many airline passengers have since transitioned from carrying wired headphones to Bluetooth only, leaving them in the lurch when attempting to use entertainment systems with their own preferred headphones while flying.
After years of various suppliers claiming that adding Bluetooth capabilities to their systems was impossible due to limited RF spectrum available in the cabin, the tone from Panasonic Avionics and Safran (formerly Zii) has changed dramatically.
Panasonic Avionics recently rolled out Bluetooth capabilities on its eX3 inflight entertainment platform on the China Eastern A350, but with some restrictions. Bluetooth is only available in the business class cabin, and only to airline-provided bluetooth headphones, not to passengers’ own bluetooth headphones.
Panasonic says full Bluetooth capability for personal devices will be available on the NEXT hardware platform.
Safran, however, says it has already cracked the code to roll out Bluetooth to all passengers, including their own headphones, as a part of its RAVE Ultra inflight entertainment system. The system will begin shipping to seat manufacturers in the third quarter of 2019.
“We have, through special software and special hardware that’s part of Ultra … that takes the Bluetooth emission from a circle down to a conical shape, and limiting the power back into a 3ft to 4ft conical shape,” senior director, sales and marketing Jared Siqueland said at the Aircraft Interiors Expo (AIX) in Hamburg. “And now you have a very controlled emission, in terms of who is sitting in front of the display.”Aside from the possible spectrum crunch on board, managing the long list of in range devices in pairing mode needs to be controlled. While traditional Bluetooth range is approximately 33ft, give or take, that would possibly include dozens of devices cluttering up the list. With these hardware and software limitations, passengers need to be physically close to the screen for pairing to be achieved.
“Airlines love it,” exclaimed Siqueland.
Safran explained that the cabin-wide Bluetooth deployment has been approved by both Boeing and Airbus. “We went to Airbus and we’re on an A321 … tested it and proved it out,” said the Safran executive. “At Boeing we went up to their test facility in Seattle and proved it out there. They already bought off on the technology.”
At a demonstration in Safron’s booth at AIX, pairing to a set of Apple AirPods occurred without issue. The audio cut out after taking a few steps back from the screen; a shorter distance than what would be expected with traditional Bluetooth.
The number of ways audio can be accessed from embedded systems has ballooned, from traditional 3.5mm headphone jacks to USB Type A to USB Type C and even magnetic contacts. Bluetooth capabilities, however, represents the first practical wireless method, which will lead to less clutter.
