sensor analytics
Posted by Thang Le Toan on 20 February 2018 01:30 PM

Sensor analytics is the statistical analysis of data that is created by wired or wireless sensors.

A primary goal of sensor analytics is to detect anomalies. The insight that is gained by examining deviations from an established point of reference can have many uses, including predicting and proactively preventing equipment failure in a manufacturing plant, alerting a nurse in an electronic intensive care unit (eICU) when a patient’s blood pressure drops, or allowing a data center administrator to make data-driven decisions about heating, ventilating and air conditioning (HVAC).

Because sensors are often always on, it can be challenging to collect, store and interpret the tremendous amount of data they create. A sensor analytics system can help by integrating event-monitoring, storage and analytics software in a cohesive package that will provide a holistic view of sensor data. Such a system has three parts: the sensors that monitor events in real-time, a scalable data store and an analytics engine. Instead of analyzing all data as it is being created, many engines perform time-series or event-driven analytics, using algorithms to sample data and sophisticated data modeling techniques to predict outcomes. These approaches may change, however, as advancements in big data analytics, object storage and event stream processing technologies will make real-time analysis easier and less expensive to carry out.

Most sensor analytics systems analyze data at the source as well as in the cloud. Intermediate data analysis may also be carried out at a sensor hub that accepts inputs from multiple sensors, including accelerometers, gyroscopes, magnetometers and pressure sensors. The purpose of intermediate data analysis is to filter data locally and reduce the amount of data that needs to be transported to the cloud. This is often done for efficiency reasons, but it may also be carried out for security and compliance reasons.

The power of sensor analytics comes from not only quantifying data at a particular point in time, but by putting the data in context over time and examining how it correlates with other, related data. It is expected that as the Internet of Things (IoT) becomes a mainstream concern for many industries and wireless sensor networks become ubiquitous, the need for data scientists and other professionals who can work with the data that sensors create will grow -- as will the demand for data artists and software that helps analysts present data in a way that’s useful and easily understood.

Customize desktops with application virtualization tools
Posted by Thang Le Toan on 20 February 2018 08:16 AM

With application virtualization tools, IT can deliver some of the customization users desire, even in nonpersistent VDI deployments.

Nonpersistent VDI simplifies management by limiting the number of golden images IT has to keep track of and lowers storage costs and requirements. It also strips users of their ability to customize their desktops because the desktops reset each time users log out.

VDI shops have a few options to give users back some level of personalization in nonpersistent deployments, including app layering and roaming profiles. They can also turn to application virtualization tools to give users back some of the customizability they crave, while allowing IT to stay in control.

How does application virtualization help?

Application virtualization tools, such as VMware ThinApp and Citrix XenApp, uncouple an application from the desktop so IT can assign it to an individual or group.

The layers of app virtualization

Application virtualization separates the app from the OS.


IT professionals can designate who the app goes to based on group membership. They can also use Group Policy Objects to assign apps to users or groups of users. The apps are available to the users or groups as soon as they log in to their desktops. Because the apps are separate from the OS, every time a user logs off of his virtual desktop, the system can reset the underlying OS without touching the user's saved settings and data within the virtual application.

IT usually does not use application virtualization in isolation. Instead, it is common to pair it with a user environment management tool, such as AppSense from Ivanti or ProfileUnity from Liquidware. Teamed up, these tools provide a holistic management approach that effectively captures the user's uniqueness and stores it for the next logon.

Intel Xeon D-2100 with VMware ESXi and Ubuntu 16.04 on Supermicro X11SDV
Posted by Thang Le Toan on 18 February 2018 05:14 PM
VMware ESXi 6.5u1 And Intel Xeon D 2100 With Supermicro X11SDV

If you have been following our Intel Xeon D-2100 Series Launch Coverage Central you will have seen that we already published the expected Xeon D-2100 series OS compatibility list. Usually, VMware is one of the laggards in terms of hardware compatibility for bleeding-edge platforms. Conversely, Microsoft Windows and Linux tend to have leading compatibility of server parts. As a result, we wanted to take an opportunity to test the Intel Xeon D-2100 platform, based on a Supermicro X11SDV-4C-TLN2F, with VMware ESXi 6.5u1.

Intel Xeon D-2100 with VMware ESXi 6.5u1

We made a short, sub 2 minute, video of our results. In the video, you will see that indeed, this worked without an issue. We made the recording using an older ISO, from August 2017, just to ensure that there has not been an update since then. The VMware ESXi 6.5u1 was the first iteration to fully support Intel Xeon Scalable and AMD EPYC which is why it is becoming popular in data centers and labs.

At the start of the video, you can see the machine running Ubuntu 16.04.3 LTS prior to installation. In essence, while recording we realized that we covered Ubuntu compatibility inadvertently. Ubuntu was installed without a single additional driver needing to be added, and we have both GUI and server versions running on the Supermicro X11SDV generation platforms.

We wondered why we did not need to install an additional set of drivers, and the reason quickly became clear: Intel did something very smart with this generation. At the heart of the platform’s I/O is Lewisburg. If that sounds familiar, it is because the Lewisburg generation of PCH is what was introduced on the Intel Xeon Scalable series of mainstream server processors.

For those deploying these embedded platforms, it means that we expect broad out-of-box OS support for the Intel Xeon D-2100 series platforms out of the gate. That is not something we always see with new embedded platforms, such as the Intel Atom C3000 series.

Now, the question remains, if you are working with VMware ESXi virtualization solutions is the Intel Xeon D-2100 series the right platform. We think there is a place for it in highly space-constrained situations or those that require low power, low memory capacity, and high compute performance. You can check out our Platform Power Consumption and First Benchmarks of the Intel Xeon D-2100 Series and we will have lots more on STH in the near future.

Supermicro AOC-SLG3-2E4R and Supermicro AOC-SLG3-2E4 Differences
Posted by Thang Le Toan on 18 February 2018 05:07 PM
Supermicro AOC-SLG3-2E4R with Intel 750 400GB
Supermicro AOC-SLG3-2E4R with Intel 750 400GB

One question we have seen multiple times in e-mail and in the forums is: what is the difference between the Supermicro AOC-SLG3-2E4R and Supermicro AOC-SLG3-2E4 NVMe expansion cards. Users are looking for ways to efficiently use available PCIe resources to add NVMe capabilities. The 2.5″ SFF NVMe drives have the potential to add more drives to a system than their add-in-card (AIC) PCIe x4 counterparts. As a result, many users are looking to add NVMe expansion capabilities to their existing systems yet there are few currently available options. Two options we found as part of earlier research were the Supermicro AOC-SLG3-2E4R and Supermicro AOC-SLG3-2E4. Information was sparse on these so we did a bit of digging and have the differences.

The Supermicro AOC-SLG3-2E4

The Supermicro AOC-SLG3-2E4 has a PLX PEX 8718 chip to handle adding two PCIe x4 SSDs into a single PCIe x8 or x16 slot. PLX (now part of Avago) makes PCIe switch chips that help aggregate PCIe lanes when a CPU’s PCIe controller would otherwise be maxed out. The PEX 8718 is a 16 lane 5 port PCIe 3.0 switch (specs here.) That makes sense with two x4 lane sets going to the drives and x8 going to the host. This is certainly the more complex of the two and costs $100 more at $249 on Amazon or ebay.

The Supermicro AOC-SLG3-2E4R

The Supermicro AOC-SLG3-2E4R – $149 (Amazon or Ebay but I got from ebay) is a lower cost part with no PLX chip onboard. It also therefore consumes less power but has a much tighter compatibility matrix.

Results with the AOC-SLG-2E4R

In a quest to add 2.5″ SFF PCIe/ NVMe capabilities to existing systems we started working on an experiment with the lower cost AOC-SLG3-2E4R and an Intel 750 400GB SSD which comes with the required cable. We were cable limited, not drive limited but were able to test the card with a variety of single drives.

The overall results were mixed. Initially we had success with several motherboards which apparently had onboard PLX controllers and with a Xeon D test system, even when using non-Intel 750 SSDs. For example, here was a Supermicro Xeon D platform with a Dell branded Samsung XS1715 800GB drive which worked (although according to the slide above it should not have.)

We did see a few issues on motherboards without PCIe switch chips.

Bottom line

Right now we are thinking the AOC-SLG3-2E4 may be the better option from a compatibility standpoint. We should have a card by the second week in June to verify. Keep checking this thread in the STH forums for more updates.

One potentially interesting implication is that a 32 lane PLX PCIe switch chip could be used to build a PCIe x16 to 4x NVMe card or the technology could potentially allow over subscription of drives to PCIe lanes, greatly enhancing the ability of server vendors to add more PCIe SSDs.

app virtualization or vApp
Posted by Thang Le Toan on 17 February 2018 01:17 AM

App virtualization (application virtualization) is the separation of an installation of an application from the client computer accessing it.

From the user's perspective, the application works just like it would if it lived on the user's device. The user can move or resize the application window, as well as carry out keyboard and mouse operations. There might be subtle differences at times, but for the most part, the user should have a seamless experience.

How application virtualization works

Although there are multiple ways to virtualize applications, IT teams often take a server-based approach, delivering the applications without having to install them on individual desktops. Instead, administrators implement remote applications on a server in the company's data center or with a hosting service, and then deliver them to the users' desktops.

To make this possible, IT must use an application virtualization product. Application virtualization vendors and their products include Microsoft App-V, Citrix XenApp, Parallels Remote Application Server, and VMware ThinApp or App Volumes -- both of which are included with VMware Horizon View. VMware also offers Horizon Apps to further support app virtualization.

The virtualization software essentially transmits the application as individual pixels from the hosting server to the desktops using a remote display protocol such as Microsoft RemoteFX, Citrix HDX, or VMware View PCoIP or Blast Extreme. The user can then access and use the app as though it were installed locally. Any user actions are transmitted back to the server, which carries them out.

Benefits of app virtualization

App virtualization can be an effective way for organizations to implement and maintain their desktop applications. One of the benefits of application virtualization is that administrators only need to install an application once to a centralized server rather than to multiple desktops. This also makes it simpler to update applications and roll out patches.

In addition, administrators have an easier time controlling application access. For example, if a user should no longer be able to access an application, the administrator can deny access permissions to the application without having to uninstall it from the user's desktop.

Quick overview video on Microsoft
Application Virtualization (App-V)

App virtualization makes it possible to run applications that might conflict with a user's desktop applications or with other virtualized applications.

Users can also access virtualized applications from thin clients or non-Windows computers. The applications are immediately available, without having to wait for long install or load operations. If a computer is lost or stolen, sensitive application data stays on the server and does not get compromised.

Drawbacks of app virtualization

Application virtualization does have its challenges, however. Not all applications are suited to virtualization. Graphics-intensive applications, for example, can get bogged down in the rendering process. In addition, users require a steady and reliable connection to the server to use the applications.

The use of peripheral devices can get more complicated with app virtualization, especially when it comes to printing. System monitoring products can also have trouble with virtualized applications, making it difficult to troubleshoot and isolate performance issues.

What about streaming applications?

With streaming applications, the virtualized application runs on the end user's local computer. When a user requests an application, the local computer downloads its components on demand. Only certain parts of an application are required to launch the app; the remainder download in the background as needed.

What is the biggest benefit of application virtualization?

Once completely downloaded, a streamed application can function without a network connection. Various models and degrees of isolation ensure that streaming applications do not interfere with other applications, and that they can be cleanly removed when the user closes the application.

Compare top tools for deploying virtualized applications
Posted by Thang Le Toan on 17 February 2018 01:10 AM

Take a look at some of the top tools for publishing, streaming and delivering virtualized applications, including App-V, XenApp and ThinApp. Find out how each tool works and what situations are the best fit for each one


Organizations looking to deliver virtualized applications have a lot of tools to pick through, but Citrix, Microsoft and VMware app virtualization, remoting and publishing offerings sit at the top of the market.

With these tools, admins can deploy and manage Windows applications and computing resources from the safety of the data center, and users can access those remote apps and data from multiple endpoints.

ThinApp is one of VMware's top application virtualization tools. An agentless tool available as part of the Horizon Suite or as its own product, ThinApp has been around since 2008, but VMware also added an app layering product, App Volumes, and Remote Desktop Session Host (RDSH) capabilities to the Horizon suite. Microsoft's tool is App-V, with a centralized management console and agent-based installation approach. Finally, Citrix brings XenApp to the table. This virtual app delivery tool notably allows more than one user to independently access a server at the same time.

Find out more about each of these app delivery tools and a few other options before making a decision about how you'll deploy virtualized applications.

Blockchain to give global LGBT community a louder economic voice
Posted by Thang Le Toan on 15 February 2018 11:24 AM

Blockchain will underpin a global platform that aims to give the LGBT community a more powerful economic voice

A global lesbian, gay, bisexual and transgender (LGBT) community organisation is using blockchain to create a global platform and digital currency to connect businesses and consumers in the trillion dollar Pink economy.

The initiative from the recently formed organisation known as LGBT Token will give the LGBT community a global economic identity and louder economic voice.


Blockchain technology is key. It will enable members of the LGBT community to register and self-manage their membership and their combined economic transactions to be secured and measured.

The power of the pink dollar economy is not well understood as much of the spending is not categorised. If merchants can better understand spending habits, they could better target the right products and services.

According to a whitepaper from LGBT Token, if the LGBT community were a country, it would be the world’s fourth-largest economy, with a GDP of $4.6tn.

“However, the power of the Pink Economy is often underestimated. LGBT Token will make this global economic muscle tangible and visible – by establishing a LGBT-centric digital asset to allow borderless transactions and exchange among an already global community, while safeguarding its members’ identities,” said the whitepaper. By understanding the group economic power, the community can exert more influence on businesses and even governments.

The project is the brainchild of Christof Wittig, CEO at Hornet, a social network for gay men, which has 25 million members globally. He said the LGBT Foundation will be open to the entire LGBT community, which is between four and seven percent of the world population.

Wittig said LGTB Token will use blockchain to register and manage the identity of members of the LGBT community.

Blockchain can help members self-administrate the community with secure and tamper-proof records. An LGBT cryptocurrency will be created, which, through a digital wallet, members can spend on accredited products and services.

“LGBT community members are not accounted for by any government – and shouldn’t be – so it is difficult for them to organise. Blockchain solves this by allowing people to define their membership,” said Wittig.

Members can then buy as consumers or supply as merchants, with services designed for the preferences of the LGBT community. “Today many businesses derive a significant proportion of their revenue from the LGBT community which is sometimes called ‘the pink dollar’ but it is not tracked,” he said. The platform could introduce permission based marketing where merchants and brands understand what the consumers really want.

Wittig added there will also be funds allocated to charitable LGBT causes by the community. This already happens, but the platform will reinforce this. “With the LGBT community organising itself, we can do this on a large scale.”

The project will create the first global LGBT community. “At Hornet, we have a global community, but this is focused on gay men and their needs,” he said. “This is the first time the global LGBT community will be able to self-organise. Blockchain is a reflection of the transient nature of the community, as it is free of borders and there is not government or organisation controlling it.”

Hornet, which is driving the blockchain implementation at LGBT Token, is a large technology company with experience, and will also work alongside third-party suppliers.

Three VDI best practices you need to know
Posted by Thang Le Toan on 15 February 2018 11:21 AM

VDI comes with challenges around graphics support, user personalization and more. Administrators should keep in mind these tips for deployment success.

In the early days of the technology, storage capacity and network bandwidth posed major challenges. The rise of converged and hyper-converged infrastructure addressed many of those problems, but now, VDI administrators face new challenges.


At VMworld, a panel of end-user computing experts fielded questions from attendees about solving these problems and shared VDI best practices for achieving success.

Do I need GPUs for VDI?

"The answer is trending toward yes," said Sean Massey, senior technical architect at Ahead, an IT consultancy in Chicago.

Traditionally, there haven't been a lot of everyday use cases for GPUs on virtual desktops, and they were difficult to implement and manage. But now, with the advent of virtual GPUs and vMotion for GPUs in the works, that's changing, Massey said. And in Windows 10, even common applications, such as Microsoft Office and web browsers, take advantage of the GPU, and the user experience (UX) can suffer without it, he said.

With GPUs, the benefit is way more than the cost at this point.
Earl GayRoundTower Technologies

The cost of GPU technology can be a concern, but because delivering a strong UX is so important to VDI best practices, it's a worthwhile investment, said Earl Gay, practice manager at RoundTower Technologies, an IT solutions provider based in Cincinnati.

"VDI's not going to be super cheap anyways," he said. "With GPUs, the benefit is way more than the cost at this point.

What are the barriers to desktop as a service?

Despite its promise of cheaper virtual desktops, desktop as a service (DaaS) has hidden costs that can make implementation prohibitive, said Dane Young, virtualization practice manager at Entisys360, an IT consultancy based in Concord, Calif. Organizations must consider the total cost of ownership of DaaS and determine if it makes financial sense.

Some cloud providers offer basic desktop virtual machines and leave advanced tasks, such as image management, policy enforcement and patching, up to IT.

"You need to ask, 'How much of this is the provider taking on, and how much am I going to be responsible for?'" Young said.

Deploying specific applications and supporting users are other DaaS challenges, Gay said. A provider that offers those capabilities is more valuable, he said.

How do you maintain personalized application settings?

The key to user personalization is identifying where applications write their settings to on the desktop, Massey said.

It's usually easy to find these locations in professional, off-the-shelf applications, but "it's the homegrown ones that are a huge pain in the butt," Young said.

How does your company handle personalization in VDI deployments?

User environment management products can help VDI administrators deal with this issue, but it's still a complex task. Small and medium-sized businesses -- especially those in which one admin handles all VDI issues -- may not have the resources to take on this task.

"Sometimes, the operational burden is too heavy," Gay said.

It's also important to learn what users' expectations are regarding desktop personalization. The ability to set a custom wallpaper, for example, can go a long way, said Matt Heldstab, enterprise systems engineer for the Minnesota State Colleges and Universities system.

"They feel it's a successful VDI project if their kitty shows up on their desktop," he said.

Journey to the center of a successful VDI project plan
Posted by Thang Le Toan on 25 January 2018 11:05 AM

Once IT has evaluated DaaS and on-premises VDI, the next choice is nonpersistent or persistent VDI. The differences in user experience, endpoint devices and licensing make nonpersistent and persistent VDI a definitive decision for an organization. IT must determine the use case of the virtual desktops, the clients available to the organization and the overall cost of the deployment first.

Organizations that have multiple users operating on a shared device should turn to nonpersistent desktops. This setup uses a golden image as a universal virtual desktop template and refreshes the virtual desktop for each login.

Users cannot customize their settings or desktops with nonpersistent VDI. As a result, nonpersistent desktops require less storage and, therefore, cost less. Nonpersistent VDI works on thin clients, which also saves money for organizations. Licensing a nonpersistent deployment is per device, with costs ranging depending on the vendor IT uses.

A persistent VDI deployment is a great option for organizations that have users working with multiple devices. Each desktop is virtualized on a separate disk image that is unique to each user, so he can save settings, files and applications. These settings are always on the desktop unless the user chooses to make changes. This level of personalization requires significant room for storage, so organizations must have logical drives on which to store disk images before they are integrated back onto the virtual machine.

With persistent VDI, the endpoint devices must perform the rest of the virtual desktop computing, so thin clients are not the best option. Licensing a persistent VDI deployment is per user, and it varies in price depending on the vendor.

Large organizations that have a use case for both nonpersistent and persistent VDI can deploy both types. IT has to be meticulous on the user device policies, the type of licensing it uses and the storage architecture. Organizations such as hospitals may choose one large group, such as nurses, to share one main computer per workstation, while the hospital administrators use persistent VDI to access desktops from their laptops, desktops and mobile devices.


Battle it out between DaaS vs. VDI

As IT sets out on its desktop virtualization quest, it must consider desktop as a service (DaaS) vs. VDI. The two options differ when it comes to cost, user experience and scaling. There are specific factors IT can look at to determine which approach is best, such as the virtual desktop use cases and where it will store the data -- or if the organization would benefit from a combination of the two.

When it comes to DaaS vs. VDI, DaaS has more flexibility for costs and scalability. DaaS offers subscription-based pricing for cloud-based desktops that are hosted by a third-party provider, which cuts upfront infrastructure costs and helps open up more room for data storage.

Typically, the DaaS vendor handles infrastructure and software issues, while IT still maintains management over user accounts. Organizations invested in DaaS also have the opportunity to scale with greater ease, thanks to the subscription option and data storage elasticity from the cloud.

Don't count VDI out when it's in the DaaS vs. VDI ring. When deploying VDI, the virtual desktops live in an on-premises data center that IT manages. The on-premises back end gives IT complete control to develop and customize virtual desktops, control and manage updates and data traffic, and provide personalization unique to the organization's needs. The additional control of IT over virtual desktops can tighten security because IT has a direct look into how everything runs.
