Containerised Storage

In the process of checking out our datacentre expansion options I have been meeting with a number of vendors. Today I met Verari Systems who manufacture high density blade based storage solutions and sell datacentres in a container. Yes that’s the same type of container you see hauled around on the back of trucks world-wide. […]

IPv4 – the end is nigh?!

The IPv4 situation is already known to geeks everywhere. This is the protocol version that has been used by IP networks everywhere since the year dot (approximately). The number of IPv4 addresses the world can use is fixed because these addresses use 4 Bytes of data. The growth in IP networks everywhere is consuming IPv4 addresses at lightning speed. […]

Wi-Spy for troubleshooting Wireless LAN

Wi-Spy is an impressive gadget used by our Tech Support team when they troubleshoot a customer’s network. Wireless Local Area Networks are often to blame if someone is experiencing slow internet access. Hotspots operate as a hub which means they can easily get congested if they have too many users. It is easy for a corporate WLAN  […]

CCNA Bootcamp

A good way to finish the week. I discussed the importance of training last week. Well this week the lucky members of the team did the CCNA Bootcamp training provided by Global Knowledge. I have to say the quality of the training was top notch and we couldn’t have asked for a better tutor in Brad […]

Virtual Machines for Email Platform

We have stepped up our use of Virtual Machines at network level at Timico and recently rolled out a significant number of Xen based platforms. Xen (see Xen.org).  For those that don’t know a Virtual Machine is a virtual server that can run on multiple hardware devices simultaneously but can be seen as a single entity […]

Ubuntu – The Intrepid Ibex

Ubuntu, for those of you who don’t class yourselves as anoraks, is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need – a web browser, presentation, document and spreadsheet software, instant messaging and much more. The Ubuntu website’s own words. Basically a free alternative to […]

Network Monitoring Network Monitoring

So good they named it twice. Actually I was trying to think of a sexy title for network monitoring but I couldn’t. Network monitoring is the unsung hero of a communications business. A network has to have monitoring in place to allow staff to keep an eye its health but it isn’t what might be called […]

The buzz of the Network Operations Centre

It always gives me a great buzz to sit in our NOC. It’s because when we started Timico only 4 years ago there were only four of us sat in the room of Tim Radford’s parents’ stable block (it was cheap and there was no room at the inn anyway). Now on a normal working […]

Data centre power consumption

Power consumption is, as I’m sure you are all aware, a huge issue when building data centres today. The data centre giants such as Google and Microsoft build their facilities close to sources of hydroelectric power in order to minimise their operating costs. An ironic fact about data centres is that it takes almost as much power […]

Network Security

One subject that is dear to the heart of a major corporation is network security. One often hears anecdotal evidence of the huge steps companies take to protect their intellectual property. I even knew a company whose boardroom was “secure” and had regular scans for listening devices. Also there have been a number of high […]

Virtual Server Virtuosity

At Timico we recently installed a complete network solution for a customer in the UK. The requirement included installation of a domain controller, file and print server, Microsoft Exchange 2007, Microsoft SQL server various databases and for their document management system and a Citrix ZenApp for home workers to run the document management system remotely. […]
