  3. 3. Message from the PresidentKen Martin, President of Diversified Technology, Inc.At Diversified Technology, Inc. we have always strived to provide a quality product that not only fills the current needs of our customersbut also those of their future advancements. This requires forward thinking about the challenges that DTI will face, as well as theend-customers program. Trying to predict what market changes various industries will face while ensuring your current deliverables arecompleted on time, proves oftentimes to be a complicated task.Some of the future changes DTI is focusing on are covered in this issue of our custom publication. Two of the articles coverAdvancedTCA and the transitional challenges facing the move from 1G and 10G to 40G. As with most things, our product line onlydictates a very minor part of the global changes that are needed to make 40G implementations both practical and functional in Telecomand other industries. How these challenges are addressed shows the level at which DTI strives to understand and implement the needsof its customers into a design, and demonstrates that we dont just pass on hardware built to spec to them. We actually put many hoursof consideration into developing a real solution for their application—not just hardware and software.A second development mentioned is within our On-Board Vehicle Power (OBVP) program. The 10kW system is currently beingmodified through EMI (electromagnetic interference) testing as well as having numerous hardware and software changes to allowincreased output of 30kW mobile power to our soldiers. Being an embedded computer provider, DTI knows first-hand that with increasedprocessing and computing performance comes the need for even more raw power. Thats why we had a plan in place from day one tomove this product line on to 30kW and beyond.I also want to point out a new product line that is growing at a rapid pace for us at Diversified Technology: our Gale Series of Wind PowerInverters. These inverters were developed for a single customer through the knowledge we acquired dealing with the OBVPinverters, and our efforts have since grown to multiple customers throughout numerous countries. The first unit is a 12kW inverter thatperforms in a NEMA 1 enclosure. The second is a smaller 6kW inverter that performs in a NEMA 3R enclosure, and is designed tohandle a smaller class of wind turbines. Both of these systems are firsts for us in the growing wind power and alternative energymarket. We are having great successes and, through these successes we are learning many things that we feel could enhance ourproduct line even further. Through customer feedback on these products and market studies, DTI is now in development of a thirdsystem that will offer more functionality and features than our current generation of inverters.All of our embedded computing products and power inverters can be enclosed in chassis that are designed and manufactured in-house.DTI is constantly updating our systems approach to provide our customers with not only subcomponents, but with a fully integratedsolution that gets them ahead of their competition.Throughout its 39 year existence, Diversified Technology, Inc. has designed everything from industrial control boards, Ethernet switches,hex-core processing blades, and integrated suitcase laptops to ruggedized mobile power systems, UHF and VHF antennas, and nowwind inverters. As a company we aim to use all of these engineering experiences in serving our customers and to truly offer themdiversified product solutions.Ken MartinPage 4DTI Wired : Get Connected with Diversified Technology, Inc.
  4. 4. Providing a Cohesive Approach to Embedded Computing and Power SolutionsLossless EthernetAdvancements in Next Generation NetworksThe Ethernet technology family has grown and evolved Rbridgessignificantly over its 35 year history. Every few years a set of Today’s L2 Ethernet networks use Spanning Tree Protocol (STP)changes comes along that revolutionizes the way Ethernet for loop prevention. STP blocks links that create loops, and itnetworks are used. Bandwidth increases are the most noticeable takes several seconds to recover from topology changes.changes, but they are not always the most important. Even with Rbridges address these shortcomings of STP.40G (and 100G) Ethernet at our door step, there are otherimportant changes coming to Ethernet in next generation Rbridges are Routing bridges. Rbridges bring some routingdevices. For the first time a group of new technologies can be functionality to bridges (switches), as the name suggests.combined to make Ethernet lossless, which greatly extends the Rbridges use the IETF TRILL (Transparent Interconnect of Lotsnumber of applications suitable for Ethernet. of Links) protocol to discover the network topology and provide optimal pair-wise forwarding paths.

TRILLdifferences between two devices, they can loose frames due to supports any arbitrary network - from a simple tree to aa topology changes in the network, and finally, they can lose complex mesh and all links in the network can be active.

All of these reasons for AdvancedTCA networks and high availability networks indropped frames need to be addressed in order for Ethernet to be general, rbridges allow for much better utilization of resourceslossless. Luckily for us, all of these problems have been solved because all redundant links can be active at the same time.with the technologies outlined below. Rbridges with TRILL have several advantages over traditional switches with STP, including instant recovery from topologyTiming changes, shorter paths, greater bandwidth, and lower latency.Ethernet devices are required to have local clocks with anaccuracy of 100 parts per million or better.

  8. 8. Providing a Cohesive Approach to Embedded Computing and Power SolutionsAdvancedTCA SwitchingLayer 2 Failover Feature R AdvancedTCAToday’s data center environments demand performance andreliability at much greater levels than even 5 years ago. Uptimefor application and network resources reaching 99.999%availability is becoming a more common requirement and notjust the rare case.Application and web server redundancy can be achieved by theuse of high performance load balancers, server clustering andvirtual host control applications. Resiliency in the network isprovided by routing protocols such as OSPF and BGP forrouting at layer 3 in conjunction with non-stop forwarding andredundant hardware features. Protocols such as VRRP providefor host IP gateway redundancy.Layer 2 Network RedundancyIn the past, multiple paths within the VLAN or broadcastdomains were also needed in the case of link or device failures. With multiple paths to the same points in these networks, loopsare formed which left unchecked create broadcast storms thatcan bring networks to a standstill. The spanning-tree protocol(IEEE 802.1D) is implemented in layer 2 networks to automat-ically block these loops so only one path exists eliminating loopsin the topology. As a result of link failures, spanning-tree will With just one connection to the host, path redundancy can onlyun-block previously blocked ports to provide for path be achieved by installing the link between switch C & D.

These operations can take as long as 30 seconds than one physical connection can be configured to the host butand can impact traffic in other parts of the network and not just traditionally host IP stacks had no way of automaticallylocal to the device on which the failure occurred.

Page 9 DTI Wired : Get Connected with Diversified Technology, Inc.
  9. 9. IPMP Operation ExampleIPMP can be configured to monitor failures in 3 different ways. To monitor remote path failures, the IP gateway can be pinged atspecified intervals or ARP requests for the IP gateway can also be sent. The link state of the host NIC itself can also be monitored. Inthe event of a failure condition, IPMP will move the owner of the IP address to the secondary NIC card and generate a gratuitous ARPrequest from that NIC to enable MAC address learning on the new path to the IP gateway. When using IPMP, the redundant link betweenswitch C and D can now be removed eliminating the spanning-tree blocked port from the topology.Page 10DTI Wired : Get Connected with Diversified Technology, Inc.

Providing a Cohesive Approach to Embedded Computing and Power SolutionsWind Farms Big Wind versus Small WindWind Farms are groups of turbines that are interconnected via a The overall wind turbine market can be divided in to 3 classes:power collection system and communications network used in 1. Small Wind Turbinesaggregate to generate power. Wind farms may be located in These turbines have power ratings of 100kW and belowopen farmland or on off-shore platforms that take advantage of and are generally for residential and small businesses.coastal winds. 2. Community Wind Turbines These turbines have power ratings between 200kW and 1MW. 3. Large Wind Turbines These turbines have power ratings above 1MW. DTI’s Focus on the Small Wind Turbine Market Small Wind Turbines are turbines whose production capability is roughly 100kW or less. Typically used to power homes, businesses, farms, and other single-site units, these turbines may be set up as stand-alone systems or interconnected to the grid. The Small Wind Market has drastically increased growth, in part due to lower installation costs. There were an estimated 19,000 Small Wind turbines installed during 2009, amounting to a 78% increase in total kW power output and adding 17.3MW of installed energy capacity. The total Small Wind capacity for theLarge scale wind farms may be directly connected to the power United States is estimated to be 80MW.grid in order to supplement traditional energy production forms.Smaller turbine applications are typically used to provideelectricity to isolated or remote locations or to provide powergeneration for a small facility. Electric utility companies will“buy back” energy surpluses produced by smaller domesticturbines, which is a process known as “Net Metering.” Thevalue of the energy surplus produced by a small-scale, grid-tiedturbine is credited to the turbine’s owner. Net metering and theclean, renewable, and sustainable aspects of wind make it anattractive primary or secondary energy source for manyapplications.The amount of energy generated by a wind turbine is a functionof the frequency and speed of wind a given location receivesover time.

DTI designed its Gale Series to comply with standards set for grid-tied operation, safety and electromagnetic compatibility including: UL 1741 and CSA C22.2 No. 107.1-01. The Gale series also accepts a wide range of input voltages from 85 to 400VAC. Once the 85VAC input is reached and the inverter initializes, the input voltage can then drop to 50VAC input before the inverter can no longer produce power. This allows the inverter to produce power even during light wind velocities. NEMA 1 (12kW) and NEMA 3R (6kW) enclosures provide operation in controlled elements that protect the internal components of the inverter. The inverter also includes built-in disconnect for utility grid interaction which is isolates the inverter from the grid during any faults. The unit also has built- in thermal sensing, and will reduce output power or shutdown automatically if temperatures exceed safe operating conditions.

For example, having access to120 vac, 60 Hz in a remote location to power up communica-tions, computers, and other specialized equipment is needed.Mobile power must also be provided for the vast array ofcomputer and communication equipment assembled in aTactical Operating Center (TOC). Mobile power can also beused to run advanced laser weapons. Why can’t someone develop a means to provide AC power by utilizing the vehicles engine as the primary source? Thats exactly what the concept of On-Board Vehicle Power (OBVP) addresses. However, the laws of physics apply and to develop a 10kW OBVP system for installation on a vehicle, such as a HMMWV with a 28 VDC alternator, that alternator must put out 400 to 450 amps. The fact is that these alternators are already in the Armys inventory today. While the military has aggressive programs in place to move toward Hybrid Electric HMMWVs there is a sizeable base of existing vehicles that are candidates to be retrofitted with 10kWThe examples above will require different levels of power.

The modular design method of the inverters main components and the method of connecting the peripheral components means that the OBVP system can easily be removed from one HMMWV, returning the vehicle to its original configuration, and quickly and readily installed on other vehicle platforms as needed.

  24. 24. Providing a Cohesive Approach to Embedded Computing and Power SolutionsThe Challenges in Gaining 30kW of Mobile Power Realizing Tactical Goals with OBVP SystemsAs mentioned previously, the laws of physics apply and As advances in battlefield technology force the requirements ofgenerating 30 kilowatts of AC power from the engine and higher and more mobile power solutions, On-Board Vehicleelectrical system of a HMMWV is not an easy task. Power units will find their way into many deployments. The military’s focus on faster, lighter, and stronger requires the use of new technology to power the next the generation of computer and communication systems. These systems and where they will be deployed will all require new mobile, rugged, power solutions. Trailer-towed and Skid-mounted power generators fail in these regards, as they add bulk, reduce mobility, and require external fuel (diesel) to operate, which further reduces the cargo capability of a military vehicle. Mobile Vehicle Power systems, like Diversified Technology’s VPS10K, that draw power directly from the alternator and do not impede much-needed cargo space will be the go-to solution for the deployment of on-battlefield systems in the 21st centuryThere are three main challenges to address in designing military.a 30kW On-Board Vehicle Power system: Article written by:1) The transfer of power from the prime mover, which is the HMMWVs engine, to the alternator that develops the voltage necessary for input to the inverter. All of the mechanical losses must be taken into account, as well as the needs of the vehicle itself and the power needed to be supplied to the inverter. To this end, the design of the system to transfer power from the engine to the alternator is very rigorous. Various systems have been examined and Rich Prescott the most efficient method will be adapted. Power Applications Engineer2) +28VDC is not enough to generate 30kW of AC power. A new alternator is needed that converts the engines power to a voltage high enough to allow the inverter to output 30kW of AC power. This new alternator has been designed and tested and has shown that it is possible to generated 30kW of power with an OBVP system as opposed to pulling a heavy diesel behind the HMMWV.3) The electronics necessary for such a high power level generates a lot of heat. Clever packaging techniques must be used to make the inverter fit in the allotted space and to function well under all conditions. Cooling the electronics cannot be accomplished with convection cooling due to size and weight constraints. This task is possible with liquid cooling and that creates it own set of challenges to the OBVP system designer. Among them are primary heat transfer, circulating the coolant and the critical heat exchanger interface with the inverters electronics.

  26. 26. Providing a Cohesive Approach to Embedded Computing and Power SolutionsCTO Cornerby Joe McDevitt, Chief Technology Officer I like to joke that at times the position of CTO requires predicting the future, so let’s see how accurate I am at this. The Economy There will be no overnight turn around, but more of a slow gain akin to the long recovery seen in 1990s Japan. We have not seen the price declines and deflation that Japan saw, but everything about this economy, from an Engineer’s view, looks as though there is a similarity between now and Japan’s economic problems of the 1990s. I am naturally a technology bigot, believing that it can heal everything. Technology developed for World War I helped the boom of the 1920s. I consider the boom of the 1980s fueled by personal computers. We now need a technology shift to recover, and the best bet I have is switching to a hydrogen/natural gas economy instead of an oil-dependent one, and technology would be needed to make that shift. Solar, biomass and wind will help, but we need something revolutionary like the airplane. My dark horse pick for that technologyis Artificial Intelligence, but not your father’s AI. I am thinking of the AI of Jeff Hawkins “On Intelligence.” I believe we will see a deployment ofthat in the 1st half of this decade on a system that will be “taught” more than “programmed”.AdvancedTCAThe jump from 10G to 40G Ethernet will likely see a 4x increase in AdvancedTCA usage. With nearly all of the interoperability problems solved,AdvancedTCA will also become a “Best-In-Breed” shop for users. Those users need not choose stovepipe and vendor locked-in models from someplayers. AdvancedTCA is already entrenched in Telecom and will not be replaced, but AdvancedTCA’s growth will come via the Military, and it willsee more success in that market than its original Telecom market – making it the Tang of the 2010s.PICMG 2.30 and PICMG 1.3CPU performance via many cores and multithreading is growing quickly. The PCI-Express bus is well supported in both current and future chipsets.This will drive some users away from 1U/2U motherboard systems and back to systems with larger slot count chassis. Use of large slot count chassiswas a mainstay of the late 1990s, but much of that was lost to the 1U/2U systems of the world in the 2000s. Some will come back in the 2010s, andthis positions PICMG 2.30 and PICMG 1.3 very well.Now that my predictions have been made, we just have to sit back and see how accurate I am.The Employees are DTI’s Most Important AssetEmployee Spotlight - Marcelo DeSouza Marcelo works in DTI’s Network Division as a Software Engineer, and is responsible for designing new features for DTI’s Ethernet switching software.
