Microsoft Demonstrates Windows to Go

Windows 8 supports installation to removable flash media via a feature called Windows to Go. Your apps, settings, and OS can all be installed to a USB stick and you can easily move that between platforms. Microsoft demonstrated Windows to Go by booting a USB stick with Windows 8 on a desktop PC that had Windows 7 preloaded on it. After the demo, Microsoft removed the Win 8 USB stick and booted a laptop using the same drive.

Although it won't be the most performant solution, Windows to Go can be an interesting solution to quickly deploying on new hardware on enterprise clients.

Wilocity Demonstrates 60 GHz WiGig (Draft 802.11ad) Chipset at CES

At CES, I visited Wilocity to learn more about their WiGig chipset and see how close they were to being production-ready. A number of news articles covering Wilocity at CES have already been posted on various sites (PCMag, ArsTechnica). So, in this piece, I will be presenting analysis of details which haven't already been covered in the articles linked above.

Wilocity is part of the WiGig (Wireless Gigabit) alliance which promises systems capable of delivering upto 7 Gbps of bandwidth in the 60 GHz spectrum. The issue with the 60 GHz spectrum is the short range, which restricts it to being an in-room technology. The WiGig specifications are being developed under the auspices of the IEEE 802.11ad standards association, and expected to be ratified early next year. However, Wilocity believes that its current chipset adheres to the draft specifications, and it should not be difficult to make it compliant with the final specifications when it gets ratified.

Every technology needs to be in the right place at the right time, and the rise of tablets and the marketing push behind Ultrabooks might just be what WiGig needs. At CES, Wilocity (in association with AzureWave) demonstrated working prototypes of their chipset in action showing how it could solve the connectivity issue for Ultrabooks (and, by extension, tablets). AzureWave demonstrated the technology at Computex 2011, but the marketing push behind Ultrabooks was yet to take off at that time. The small and slim form factor of the Ultrabooks makes it very difficult to integrate I/O ports such as eSATA, USB 3.0, RJ-45 etc. which are taken for granted by many notebook users.

The DockingZone solution from AzureWave is meant to be a stationary dock in the room where the Ultrabook is usually used. It provides all the necessary I/Os like eSATA, RJ-45, USB ports (2.0 and 3.0), HDMI, VGA, DisplayPort etc. On the Ultrabook side, the Wi-Fi mini-PCI-E connector is replaced by a similar module which integrates Wilocity's chip as well as a Wi-Fi fallback option using a Qualcomm Atheros WLAN chipset. This enables the Ultrabook manufacturer to just replace the Wi-Fi module with the WiGig / Wi-Fi combo module without any loss of original functionality (essentially creating a tri-band wireless chipset). Since WiGig is media agnostic, it can be used to transfer data, I/O or video.

Wilocity's advertised usecase is the usage of the dock as a seamless extension of the Ultrabook itself. All the devices connected to the dock appear as if they are connected to the computer directly in the Windows Device Manager.

The speeds made possible with the Wilocity chipset make sure that even simultaneous data transfer and video output over HDMI don't cause system hiccups. Data transfers easily reached speeds of 1 Gbps and, on the whole, it was quite an impressive demo. Power consumption will apparently be on par with (or slightly better) than 802.11n based systems because of the possibility of the system going to sleep within a shorter timeframe because the data gets transferred faster.

Though the 60 GHz spectrum limits the range of the systems, the technology can take advantage of beamforming and also bounce off objects to not be necessarily a line-of-sight technology. Wilocity's technology has been part of the AzureWave system and has been demonstrated in various tradeshows over the last year or so. As I mentioned earlier, any technology needs to be in the right place at the right time. Wilocity's WiGig chipset adhering to the draft 802.11ad specifications is impressive enough to have a bright future ahead if Ultrabooks take off and tablets start to get used more within a single room in the household.

AppliedMicro Demonstrates Catalina Based Platforms

The launch of the AppliedMicro's Catalina SoC for the NAS market was covered here. In a follow up to the initial coverage, we visited AMCC at CES to look at the various reference platforms in action.

The Catalina SoC (APM86491) packs a single core Power 465 processor and has a bunch of offload features for accelerated network processing. A host of high speed interfaces (including USB 3.0 host/device, Gigabit Ethernet, SATA and PCI-E Gen 2.0 ports) makes it suitable for consumer NAS systems and wireless access points.

At CES, AppliedMicro had three different reference designs (two using the APM86491, and one using the APM82181). The first one, Riviera, was a standard NAS / Media Server design. Malibu, the second reference design, was for a wireless router. PhiPhi, based on the APM82181, was for a media server with inbuilt transcoding.

Riviera

The Riviera reference design demonstrated was a 4-bay RAID5 NAS. Two drives are connected directly to the two SATA ports on the APM86491. The other two drives are connected to the PCI-E Gen 2.0 ports using a SATA to PCI-E bridge chip. One of the USB 3.0 host ports was connected to an external SSD. There were two GbE ports in the reference design, but only one of them was connected to the PC.

A simple robocopy benchmark was run to test the read and write speeds. Over one GbE port, read speeds of around 110 MBps and write speeds of around 74 MBps were observed. The USB 3.0 bandwidth seemed to be limited only by the SSD and mechanical access speeds. This sort of performance seems to be better than what I observed with the last generation platform in the WD My Book Live. It appears that
designs based on Riviera may give Marvell's NAS platform based designs a run for their money.

Another interesting aspect of Riviera was the unconnected USB 3.0 host / device port on the APM86491. A vendor could easily tweak Riviera to expose this as a device port. In that case, the unit would be a NAS / DAS (Direct Attached Storage) combo. The demo also involved accessing the files on the NAS through an iOS / Android app, but it was nothing that I hadn't already seen in action on the My Book Live.

Malibu

The Malibu reference design demonstrated was a wireless access point with two 3x3 802.11n Atheros Qualcomm radios connected to the APM86491's two PCI-E 2.0 ports.

Since the APM86491 includes hardware accelerated network processing, AppliedMicro claimed speeds of upto 650 Mbps in the above configuration (thereby implying that it could scale upto 802.11ac speeds, if necessary).The USB 3.0 host port in the design can be used to attach storage to the router. I haven't seen any router in the market currently based on an AppliedMicro SoC. So, it will be interesting to see if the Malibu platform gets converted into a shipping product.

PhiPhi

As a media enthusiast, the most interesting reference design was the APM82181 based PhiPhi. It was a home media server with transcoding inbuilt. We had already looked at the details of the APM82181 in the My Book Live review.

The reference design was a simple 1-bay NAS. It was connected to a network on which a WDTV Live SMP was also connected. The media server program running on the Phi-Phi exposed various files on the NAS to the streamer. When played back, the PhiPhi transcoded the stream to a pre-determined format and sent it to the streamer. A home media server with transcoding inbuilt could enable the device to support
DLNA renderers which don't implement support for a lot of codecs. In hindsight, the demo could have been more impressive if a mobile device capable of only playing a lower resolution stream was used instead of the WDTV Live SMP.

AppliedMicro indicated that one of the PCI-E ports on the SoC was connected to a Zenverge ZN200 chip. Before CES, we saw a joint press release by Zenverge and PacketVideo (developers of the TwonkyServer), indicating that the ZN200 could transcode videos to further expand DLNA support even in the case of very finicky renderers. Another press release by Zenverge suggested that the ZN200 could transcode upto 4 HD streams simultaneously. The only supported formats seem to be MPEG-2 and H.264 on the source side, which could limit usefulness in situations other than those involving just changes in resolution / modification of encode characteristics of MPEG-2 / H.264 videos.

The addition of a hardware transcoder to a media server is an interesting development, but the success of such a product heavily depends on performance and price. Of the three platforms demonstrated, this is the one which intrigues me the most. I am looking forward to the market debut of this interesting reference design.

Computex 2011: Intel Demonstrates Fanless 95W TDP Sandy Bridge All-in-One System

That's right, what you're looking at is a 95W TDP Sandy Bridge All-in-One system that is cooled only via large heatsinks and no fan. Heat rises upwards and is vented out of the top of the machine but Intel says it doesn't need a fan. Apparently Intel holds some patents on the design and is willing to share it with its partners.
