Top 5 Small Business Wireless Routers

Many businesses want WiFi in the office – it’s convenient, fast, and it enables your employees to be productive on the go. No matter if they’re in their office or sharing desk space with a colleague down the hall, the ability to hook up to the network and get going without having to remember to lug an Ethernet cable around and hunt for a jack is always welcome. For many small businesses, however, the luxury of buying a wireless router with all the bells and whistles isn’t always an option due to budgetary concerns.

NetApp Certification Options

In the world of certifications, there are generally a few that are common knowledge among the general IT networking world: Cisco’s CCNA and CCSP certifications, for example, are known to the majority of the IT world, as are certifications like Microsoft’s MCP program or the A+ certification for desktop support specialists. There are, however, other certifications out there that are definitely worth looking at; certifications that, while not as well-known as some of the above, are great certifications that will help you specialize in a field or niche that you’re interested in: One of these, for example, is NetApp; they specialize… View full post »

Cisco vs. Juniper For Your Network

To a network administrator planning out his first enterprise-level network, hardware is crucial: you need hardware that can run for years without downtime, almost never fail, and have an OS and features that will let you perform the most complex and convoluted networking hoops that unforeseen problems and/or management will inevitably make you run through. For many years, and for many experts, there has always been only one provider that can accomplish all of the above without fail: Cisco Systems. Though Cisco has been entrenched as the networking king for many years, another name has appeared in the running for… View full post »

Brand Name Switches: Worth the Cost?

The vast majority of network administrators have their preferred networking vendor. Whether it’s Cisco, Juniper, or HP, you’ll often hear the same old chestnuts come down from the server room. Very often, the search for a good switch is drowned out by two sides – those who insist you have to pay dearly for quality, and those who insist a switch is a switch, and the 48-port gigabit offering from anywhere is going to suit you just fine. In today’s IT world, the answer matters quite a bit. There is a very understandable need, especially in the recent years, of saving… View full post »

Google Public DNS - Performance and Security

DNS is necessary for the Internet to function properly. Unfortunately, poor network performance from DNS servers can slow down the browsing experience. While performance problems are serious, DNS is also vulnerable to even more serious security threats such as cache poisoning. Typically, the DNS servers used for browsing the Internet are either the ones run by your Internet provider or servers that you run which forward requests to the root servers (i.e. a caching-only nameserver). Fortunately for your performance and your security, there is another option. Google runs a public DNS system where you can… View full post »

Out-of-Band Management of Data Center Infrastructure

Out-of-Band Management of Data Center Infrastructure

We recently had a client who asked us to implement the simple and cost effective solution for Out-of-band management for their production data centers. The goal of Out-of-band management is to have a network access to the critical data center infrastructure when company’s network is melted, preventing you to access any devices for troubleshooting purposes. In other words this is meant to be company’s alternative way of accessing data center critical devices. The simplest solution, that we actually ended up implementing, was a static DSL line from a local ISP provider, terminated on Cisco 2611 router, using PPPoE protocol. Cisco 2611… View full post »

In-Band and Out-of-Band Network Management

One of the best practices managing your production network devices is to have both, an in-band and out-of-band system management in place. An in-band management involves managing devices through the common protocols such as telnet or SSH, using the network itself as a media. It is a common way that provides identity based access controls for better security. By doing so, it is also a good practice to segregate your management traffic from your production customer traffic. If your network is for example congested due to the real user traffic – you will at least be able to login… View full post »

Internet Service Provider Reliability

If you are in the business where your services are heavily dependent on your network, your business could be as strong as or as weak as your Internet Service Provider, or ISP for short. Shopping for your ISP service, whether it is a dedicated circuit between your offices or an internet access could be quite a journey. The most important factor to consider when trying to sign up for an ISP service is service reliability.
