Server room air conditioning choices

Written by MovinCool.com

There is no perfect choice when it comes to air conditioning for a server room. The two primary determinants are the size of the server room and the thermal load of the equipment (the demand in BTU). Here are a few of the choices available for data center cooling:

Window air conditions

Although listed here, this is not really an option. The problem with window units is a lack of reliability and the inability for technicians to service the units easily. It might be the cheapest option, but it does not belong in the data center. It does not fit any of the requirements of industrial cooling.

Wall mounted split types

These are the most common types used for smaller server rooms or areas with the limited thermal load. These are meant for public spaces and not really designed for server rooms. As a result, they lack a humidifier.

Ceiling mounted air conditioners

These are designed for server rooms. However, they are limited to thermal capacity and can handle loads of up to 40Kw. Placement of these units is critical for servicing and to avoid any chance of liquid dripping onto equipment.

In-row cooling

These units, used in conjunction with hot aisle containment are purpose-built for server room rack units. These are extremely efficient and do not require raised floors or any other special data center setup. They can even be purchased in ready made sets.

Setting up a wireless network

For home and small offices, getting specialist engineers to do a site survey is both expensive and excessive. If you want to follow a similar process as the professionals, follow the four-step process below to assess, test and adjust your wireless network for optimum performance:

Investigate

In this step determine the type of connection you have, if can you use third party routers, and if you can move the location of the router. Also, note if it’s possible to run a cable from the router to any other equipment, if not wireless extenders are the only option. Make a note of the requirements, such as the number of people who will use the network and from where in the building.

Plan

Use a rough floor plan along with the data from step one to map out where you need to install additional access points. When looking at the radius of the coverage from each router/access point, look at the specifications of the device and assume half that number. That number will account for obstruction and walls on the strength of the signal.

Test

For this step, you will need at least a single access point in addition to the router. Place the access point according to the plan in step two. Test the speed from each location against a baseline from the router or close to it.

Adjust

Based on the results from Step three, move the access point and router around for the best coverage. Be prepared for some compromises or the need for more access points for certain areas.

How to detect malware or suspicious software on your computer

The software we install on our computers is one of the biggest potential security risks. Even known software can be altered to transmit our data in the background. There are reports of hackers inserting malware into legitimate software downloads available online. Often, even the vendor does not realize that the legitimate download is spreading malware. Here are a few ways to detect any suspicious activity:

Almost every application on a modern computer will make outbound connections to the internet. Most of these connections are for updates, licensing etc. However, using applications like NetLimiter on Windows and Little Snitch on OS X, you can keep an eye on what connections are made from which apps.

Another common activity of suspicious software is to set itself to run on startup after the installation is complete. Malware does the same thing, except hidden in some obscure corner of the hard drive. Applications like BlockBlock on OS X will block and alert you when an application attempts to set itself to run on startup.

Do not plug in any unknown devices to your USB port. If a file transfer is required from an unknown USB key, ask them to email it instead. Do not allow anyone to charge devices on a laptop, even e-cigarettes have been known to carry Malware that installs when charging on a computer. Any charging should be done directly off a wall charger. The easiest way is to tell people that there is something wrong with the USB ports.

The opportunity benefits of EDI

Written by Act Data Services, Inc. 1-800-ACT-DATA

Going ahead with an EDI implementation has many benefits. There are the strategic benefits such being able to adopt new business processes. Then there are the operational benefits such as cost reduction, elimination of human error and improved cash flow. One aspect that is often not given prominence are the opportunity benefits that EDI services can provide.

There are two primary opportunity benefits: Enhanced image and competitive edge.

Most organizations have to deal with customers one way or another. These customers can be end users and consumers or other businesses. Often customer service affects how the business is seen. The product can be robust, but if the customer service is sub-par then the company image suffers. This is where using an EDI provider comes in. It provides customer service agents or staff the ability, in real-time, to see the current state of an order. This allows them to provide the customer with an accurate estimation of completion.

Competitive edge follows a similar concept. Both the strategic and operational benefits of EDI directly affect the ability of the company to respond to market changes. Potential customers can be won over with the lower costs, accurate delivery estimates, and faster order completion. This competitive edge extends to all parts of the company: customer service, sales, marketing, and management.

How APUs Play a Significant Role in Airport Emissions

APUs are being used in a dysfunctional fashion, and the environment is being ignored.

airport-terminalThe use of Auxiliary Power Units (APU) in airports is becoming excessive, environmentally harming, and costly. Furthermore, the amount of time that the plane’s jet engines are idling is adding more fuel to the fire. The push to replace the use of these APUs for ground power units (GPU) instead could effectively improve a variety of areas.

Breaking Down the Issue with APUs

The APU is designed to perform three essential functions: starting the airplane’s main engines, providing adequate power to the plane when the main engines aren’t running, and providing compressed air to the plane’s air conditioning unit. Now, if you break it down, the ground power and air conditioning unit can be easily replaced by the use of electrical equipment, which in turn will reduce emission levels. Now, this isn’t the only concern that many airports are facing today. There are also numerous issues that revolve around economics, ramp congestion, and fuel savings. There are problems that a ground power unit can fix, if utilized in conjunction with an APU correctly.

Understanding Ground Power Units

These ground power units come in a variety of electrical power levels. For instance, many smaller airports have 28 volt power supplies attached to a cart that drives out to the airplane when it is taxied. However, due to financial constraints, the push to switch to electrical power has left many ground power units operating solely on diesel. This just adds to the environmental issues that airports are currently facing.

Now, let’s move on to the problems created by APUs. The overall issue of emissions at airports are becoming a serious concern all across the country. And, APUs are playing a significant role in adding to this problem. APU usage generates three sources of emission: carbon monoxide, hydrocarbons, and nitrogen oxide. Consider the amount of flights that go on in one day – that’s one huge cluster of gas being pumped out every second. You can see why red flags are being raised all over the place.

The solution itself isn’t an easy one. There are numerous factors and limitations that must be considered. However, with the right push, and funding, there could potentially be a substantial change coming in the future. These current problems can be fixed, and hopefully there will be significant changes with the development of new technologies.

The benefits of using VANS for EDI

Written by Act Data Services, Inc. 1-800-ACT-DATA

EDI is electronically communicating with business or trading partners. The most important component of that is the actual communication between the two parties. There were times when this was done by exchanging physical discs. Unsurprisingly this was found to be inefficient and communicating via data links was adopted.

There are two ways to use communication links to transfer the EDI data. The first is to use in-house links. The other is to use an EDI provider of a VAN, also known as a Value Added Network. There are some major benefits of using VANS over in-house links:

Connectivity

When using VANS, the only concern is the link between the organization and the VAN. Any compatibility issues with other partners is not a concern. It is also much easier to manage than individual links to multiple partners. The links between the VAN and the partner is their concern. The organization need only be concerned about the EDI services.

Security

Most of the information that occurs between business partners is confidential. VANS provide a high level of security. Not only is the communication password protected, but the actual arrangements to send and receive packets has to be set up in advance on both ends.

Audit

There are complete audit trails available for all transactions. Due to the electronic nature of the system, everything is just a click away. However, not all service providers have audit trails enabled. It should be one of the requirements when selecting VANS.

What is cloud computing and cloud hosting

Written by Rack Alley

The latest buzz word in hosting and LA data center circles is cloud computing. The initial misconception was that any service that was stored or hosted on the cloud was considered cloud computing. When in reality, it is far more than that. For example, services like Google Drive and Dropbox are all online services, but can hardly be considered cloud computing or cloud services. They are just online services.

Cloud computing is more than just about the service that is provided. In fact, it is more about how the service is delivered. The main difference between online service and cloud services is that cloud services are scalable.

It is also what makes it so important. The ability to start with a server that has a certain amount computing resource (like processor and memory) and be able to increase and decrease in real-time is what sets it apart. In addition, the billing is by the hour which makes a short burst of usage possible.

This applies to all aspects of cloud services. Granular, scalable services are available for storage, databases business intelligence, AI and so much more. Without the advent of cloud computing, most of the today’s startups would not exist. It gives very small companies the ability to buy the resources they need when they need it.

It should be noted that larger organizations still run in-house and hybrid deployments but focus on LA colocation and private cloud implementations as opposed to using public clouds.

Basic devices in a computer network

A computer network is made of multiple devices that are connected physically and logically to enable communication between each other and devices outside the network. When designing a network for a workplace or for a home it is important to understand the basics of designing a network and the various components. Here is a basic rundown of the various devices.

Router

This is the device that provides a connection to an external network like the internet. Every home and office with an internet connection will connect their network to a router.

Firewall

This device sits between the router and the rest of the internal network. It provides several levels of protection for the devices and is also used to control access to certain resources. For example, a router could allow certain users to use certain services and bar others from doing so. In addition, some higher-level firewall will detect malware and other problematic traffic and block them.

Switches

Any network that requires access to physical network ports will also need a switch. A switch routes traffic internally between computers and to other devices like the firewall. A gateway is defined on each of the computers (that is usually the firewall) and that is the destination for traffic that is considered to be external to the network.

Access point

Wireless network access has become a necessity in any environment. Some organizations no longer have a physical network and access only using Wi-Fi. Access points are the physical devices that provide that access to the network.

What Makes a Digital Wallet Quality?

A digital wallet is a piece of software that helps users move money using the Internet. Modern digital wallets utilize layers of encryption in order to ensure every transaction is private. This process is called “tokenization”, and it is used to make data anonymous and create a disposable session where the transaction can take place.

All that is useful, but it doesn’t help us understand how to shop for a great digital wallet. What qualities should you look for when you’re deciding where to store your money online? Here are some thoughts on what makes a quality digital wallet.

Basics

Stanford has some helpful ideas on what basics you should be looking for as a consumer. The best digital wallets are extensible, meaning they can handle any of the payment methods you may choose to use at a given moment. Vendors also shouldn’t be able to initiate transactions without your explicit say-so, thus making security extremely important.

Low fees are another great quality to look for, and those are achieved by re-using the same technology. You’ll never get a behind-the-scenes peak at this portion, so shop around for the lowest fees you can find.

And finally, Stanford concludes that digital wallets should be able to run on any device. You shouldn’t need your PC to complete a transaction, especially since smartphone adoption rates are rising.

Other Qualities

Other qualities to look for include discounts and special offers. More digital wallets are working directly with retailers to make sure they offer personalized discounts to customers using these payment methods.

Hi-tech kitchen gadgets coming soon

Silicon Valley disruption has affected so many parts of our lives. There are startups like Uber and Airbnb that have become the catalysts for large levels of change in their respective industries. Although these can’t be classified as disruption, tech-driven change is starting to make its way to home appliances. Here are some of the changes to expect in standard home appliances in the near future:

Ovens

Recently an oven was released that can be controlled by a smartphone and has a camera built-in. The user can monitor the level of cooking through the video and control various parameters of the cooking process. Expect this to become a feature of ovens and ranges in the near future.

Washing machines

Connected washing machines will let us control the washing machine and provide notifications when cycles are complete. Put the clothes and detergent in and then start the cycle from the smartphone. Expect to be able to queue wash, spin, and dry cycles.

Air conditioners

Another appliance that will benefit from remote-control is the air conditioner. Current models have only one method of programming and it is limited to a single one and the trigger. Aside from control using a smart home hub, individual units can be controlled with vendor apps.

The future is looking good for hub driven automation as well as by vendor apps. The only danger is that some vendors might require lock-in to benefit from a connected ecosystem of appliances.
