Fusion plays its card: The Ten of Terabytes • The Register

Fusion-io has crammed eight ioDrive flash modules on one PCIe card to give servers 10TB of app-accelerating flash.

This follows on from its second generation ioDrives: PCIe-connected flash cards using single level cell and multi-level cell flash to provide from 400GB to 2.4TB of flash memory, which can be used by applications to get stored data many times faster than from disk. By putting eight 1.28TB multi-level cell ioDrive 2 modules on a single wide ioDrive Octal PCIe card Fusion reaches a 10TB capacity level.

This is some big news in the fight to be king of the PCIe SSD market. I declare: Advantage Fusion-io. They now have the lead in terms of not just speed but also overall capacity at the price point they have targeted.  As densities increase and prices more or less stay flat, the value add is more data can stay resident on the PCIe card and not be swapped out to Fibre-Channel array storage on the Storage Area Network (SAN). Performance is likely to be wicked cool and early adopters will now doubt reap big benefits from transaction processing and online analytic processing as well.

CMOS sensor inventor Eric Fossum discusses digital image sensors: Digital Photography Review

CMOS sensor inventor Eric Fossum discusses digital image sensors: Digital Photography Review.

Check out the video of the Lecture. Dr. Fossum attempts to address the societal and privacy implications of his invention the CMOS sensor. You don’t find too many scientists willing to engage in this type of presentation. And he brings the thorny issues early in the presentation so that he doesn’t run out of time to cover them by sticking them at the end.

Also interesting in this video is Dr. Fossum’s story about how he was assigned the task of improving the reliability of CCDs (charged coupled devices) that were being sent into space. Defects in the sensor could occur when a highly energetic particle entered the sensor and created a defect in the sensor itself (ruing the ability to read out data accurately from the chip). The CCD works by collecting a sample than moving it one step at a time out to the edge of the chip, where it then gets amplified and read, and recorded. So if a defect occurs, the buckets moving a particular row or column of pixels will hit the defect and alter the reading or stop it from reading altogether.

Dr. Fossum was able to get around this by building an amplifier into each pixel. This was achieved, hanks to the scaling down of micro-electronics available in silicon semi-conductors and Moore’s Law. A double-benefit of using CMOS semiconductors for the sensor is you can add all kinds of OTHER electronic circuits on the same chip as the sensor, so things get really interesting because you can integrate them on the silicon (bring up performance, bringing down costs). As Dr. Fossum says, “basically we can integrate so many things, we can create a full camera on a chip. All you do is add power, and out comes an image,…”

Also liked this quote, “The force of marketing is greater than the force of engineering…”

Lastly, he covers his research of quanta-image sensor (QIS) which sounds pretty interesting too.

Intel Responds to Calxeda/HP ARM Server News (Wired.com)

Now, you’re probably thinking, isn’t Xeon the exact opposite of the kind of extreme low-power computing envisioned by HP with Project Moonshot? Surely this is just crazy talk from Intel? Maybe, but Walcyzk raised some valid points that are worth airing.via Cloudline | Blog | Intel Responds to Calxeda/HP ARM Server News: Xeon Still Wins for Big Data.

So Intel gets an interview with a Conde-Nast writer for a sub-blog of Wired.com. I doubt too many purchasers or data center architects consult Cloudline@Wired.com. But all the same, I saw through many thinly veiled bits of handwaving and old saws from Intel saying, “Yes, this exists but we’re already addressing it with our exiting product lines,. . .” So, I wrote in a comment to this very article. Especially regarding a throw-away line mentioning the ‘future’ of the data center and the direction the Data Center and Cloud Computing market was headed. However the moderator never published the comment. In effect, I raised the Question: Whither Tilera? And the Quanta SM-2 server based on the Tilera Chip?

Aren’t they exactly what is described by the author John Stokes as a network of cores on a chip? And given the scale of Tilera’s own product plans going into the future and the fact they are not just concentrating on Network gear but actual Compute Clouds too, I’d say both Stokes and Walcyzk are asking the wrong questions and directing our attention in the wrong direction. This is not a PR battle but a flat out technology battle. You cannot win this with words and white papers but in fact it requires benchmarks and deployments and Case Histories. Technical merit and superior technology will differentiate the players in the  Cloud in a Box race. And this hasn’t been the case in the past as Intel has battled AMD in the desktop consumer market. In the data center Intel Fear Uncertainty and Doubt is the only weapon they have.

And I’ll quote directly from John Stokes’s article here describing EXACTLY the kind of product that Tilera has been shipping already:

“Instead of Xeon with virtualization, I could easily see a many-core Atom or ARM cluster-on-a-chip emerging as the best way to tackle batch-oriented Big Data workloads. Until then, though, it’s clear that Intel isn’t going to roll over and let ARM just take over one of the hottest emerging markets for compute power.”

The key phrase here is cluster on a chip, in essence exactly what Tilera has strived to achieve with its Tilera64 based architecture. To review from previous blog entries of this website following the announcements and timelines published by Tilera:

ARM specs out first 64-bit RISC chips • The Register

The ARM RISC processor is getting true 64-bit processing and memory addressing – removing the last practical barrier to seeing an army of ARM chips take a run at the desktops and servers that give Intel and AMD their moolah.

via ARM specs out first 64-bit RISC chips • The Register.

The downside to this announcement is the timeline ARM lays out for the first generation chips to use the new Vers. 8 architecture. Due to limited demand, as ARM defines it, chips will not be shipping until 2013 or as late as 2014. However according to this Register article the existing IT Data center infrastructure will not adopt ANY ARM-based chips until they are designed as a 64-bit clean architecture. Sounds like a potential for a chicken and egg scenario except ARM will get that Egg out the door on schedule with TMSC as it’s test chip partner. Some other details that come from the article include that the top end ARM-15 chip just announced already addresses more than 32-bits of Memory through a workaround that allows enterprising programmers to address as many as 40bits of memory if they need it. The best argument made for the real market need of 64-bit Memory addressing is for programmers currently on different chip architectures who might want to port their apps to ARM. THEY are are the real target market for the Vers. 8 architecture, and will have a much easier time porting over to another chip architecture that has the same level of memory addressing capability (64-bits all around).

As for companies like Calxeda who are adopting the ARM-15 architecture and the current ARM-8 Cortex chips (both of which fall under the previous gen. vers. 7 architecture), 32-bits of memory (4Gbytes in total) is enough to get by depending on the application being run. Highly parallel apps or simple things like single threaded webservers will perform well under these circumstances, according to The Register. And I am inclined to believe this based on current practices of Data Center giants like Facebook and Google (virtualization is sacrificed for massively parallel architectures). Also given the plans folks like Calxeda have for hardware interconnects, the ability off all those low power 32-bit chips all communicating with one another holds a lot of promise too.  I’m still curious to see if Calxeda can come up with a unique product utilizing the 64-bit ARM vers. 8 architecture when the chip finally is taped out and test chips are shipped out my TMSC.

HP hooks up with Calxeda to form server ARMy • The Register

Calxeda is producing 4-core, 32-bit, ARM-based system-on-chip SOC designs, developed from ARMs Cortex A9. It says it can deliver a server node with a thermal envelope of less than 5 watts. In the summer it was designing an interconnect to link thousands of these things together. A 2U rack enclosure could hold 120 server nodes: thats 480 cores.

EnergyCore prototype card

The first attempt at making an OEM compute node from Calxeda

HP signing on as a OEM for Calxeda designed equipment is going to push ARM based massively parallel server designs into a lot more data centers. Add to this the announcement of the new ARM-15 cpu and it’s timeline for addressing 64-bit memory and you have a battle royale going up against Intel. Currently the Intel Xeon is the preferred choice for applications requiring large amounts of DRAM to hold whole databases and Memcached webpages for lightning quick fetches. On the other end of the scale is the low per watt 4 core ARM chips dissipating a mere 5 watts. Intel is trying to drive down the Thermal Design Point for their chips even resorting to 64bit Atom chips to keep the Memory Addressing advantage. But the timeline for decreasing the Thermal Design Point doesn’t quite match up to the ARM x64 timeline. So I suspect ARM will have the advantage as will Calxeda for quite some time to come.

While I had hoped the recen ARM-15 announcement was also going to usher in a fully 64-bit capable cpu, it will at least be able to fake larger size memory access. The datapath I remember being quoted was 40-bits wide and that can be further extended using software. And it doesn’t seem to have discouraged HP at all who are testing the Calxeda designed prototype EnergyCore evaluation board. This is all new territory for both Calxeda and HP so a fully engineered and designed prototype is absolutely necessary to get this project off the ground. My hope is HP can do a large scale test and figure out some of the software configuration optimization that needs to occur to gain an advantage in power savings, density and speed over an Intel Atom server (like SeaMicro).

carpetbomberz:

Always nice to get an update on the elmcity project from Jon Udell. It is the ‘calendar’ of calendars and a great project showing how one can leverage open data, but at the same time confront some technological challenges too.

Originally posted on Jon Udell:

As I review and improve the elmcity hubs in selected cities, I am again reminded of William Gibson’s wonderful aphorism: “The future is already here, it’s just not evenly distributed.” Yesterday we saw that the future of community calendars hasn’t yet arrived at the University of Michigan. But today I was delighted to see that it has arrived, in a big way, for the Ann Arbor public schools. Almost all of them, it turns out, are making good use of Google Calendar to publish machine-readable calendar information. This morning I rounded up thirty of those calendars and added them to Ann Arbor’s elmcity hub, bringing the total number of feeds from 194 to 224.

Here’s the breakdown of the 309 events from the grade schools:

Abbot Elementary 8
Allen Elementary 13
Angell Elementary 7
Bryant Elementary 29
Dicken Elementary 118
Eberwhite Elementary 19
Haisley Elementary 25
Mitchell Elementary 23
