Clean-up Tool (FindFile)

       Management of information stored on our network drives is important for many reasons but a major reason is cost control. By nature, our storage continues to grow and many users acknowledge that some stored information is old or has little value. These unneeded files can be either deleted or archived, resulting in significant reductions in business unit expense. A complete storage review can be time consuming but even a cursory review could easily result in significant annual savings. Below are three search methods that can use to reduce your network storage.

• Size - largest files first. You can significantly reduce your storage by identifying and eliminating only a few files.
• Date - oldest files. These files may no longer be needed.
• Type - Certain file types are known to be large in size such as BMP, JPG and MP3 files.

       FileFind is a tool that can help you with all three of these search methods. FileFind is an Excel spreadsheet with macros that assists in managing your disk storage. Below are instructions for using this tool. Should you have problems, please contact your local IT group.
Note: Secure and efficient storage of data is critical to our business. The data belongs to Company and, as a steward of portions of that data, the storage space on the servers is there for your use. However, it is expected that each user be accountable for their own data storage or that of their group.

       Company highly recommends that you not store business data on your C: drive. Data stored in this manner is not secure, is not backed up, is difficult to share, and in many cases conflicts with company information protection guidelines.

Server Room Temperature Recommendation

       Server Room Temperature: Computer and networking equipment is designed to operate within a fairly narrow temperature range. To ensure reliable operation and the longest possible life from components you need to ensure that the temperature stays within that band.


       Even a few degrees too hot can blow a server chip.
       The cost of a catastrophic server failure can be considerable. Think how much money you would lose if your servers went down. There is the cost of replacement, but think also of lost e-commerce business, lost customer details, wasted staff time, and all the other associated costs.

What temperature is right?
       General recommendations suggest that you should not go below 10°C (50°F) or above

28°C (82°F). Although this seems a wide range these are the extremes and it is far more common to keep the ambient temperature around 20-21°C (68-71°F). For a variety of reasons this can sometimes be a tall order.
How do you maintain the right temperature?
       Purpose built server rooms are well insulated for fire precaution reasons and air conditioning is essential. In many companies however the maintenance of the air conditioning is separate from the running of the servers. If the air conditioning fails you might not be the first to know. You may even be the last.

       Even if everything is working the temperature may fluctuate during the day, from season to season, and there is always the possibility of localized hot-spots around equipment giving off lots of heat.

       Don’t be tempted to think that just because you have an air conditioning unit that is up to the job that you are safe. People working in the server room sometimes switch the air conditioning off and forget to turn it on again. Sometimes they leave doors open. Servers run hotter at some times of the day than at others, air conditioning systems sometimes run at lower power at night etc.

       What if it’s night time, your air conditioning is running at low power, and your webserver suddenly starts to work hard because the west coast has woken up? Now your machine heats up and your air conditioning can’t cool it enough. Exactly this scenario has been know to happen. Many intermittent faults and slow downs can be traced to overheating.

        Replacing old equipment can introduce a new set of problems. Newer machines run faster and often run hotter as well, increasing the burden on the air conditioning systems even more. If you’ve recently introduced new servers or modern switches, it might be time to examining your air conditioning unit to make sure it can still keep up.

       Another thing to look out for is the scenario where you turn up the air conditioning unit during the day, in order to ensure the right environment in your server room, but then don’t switch it down during the night or weekends. During the day there might be a lot of activity into and out of the server room. The server room door being opened all of the time lets warmer air into the server room thus necessitating the air conditioning system to be turned up high. At night and at the weekend, without the same level of activity, you may be running up large energy bills for no reason.

How are you going to monitor the temperature?
       You need to monitor the temperature in your server room all of the time, especially at night and weekends when nobody is around. A number of systems are available for this purpose, the Temperature Monitor range from OPENXTRA offer good products at reasonable prices. You need to measure temperatures at different points in the room to get an idea of where the hot spots might be. You need temperature measurement to be automated and reliable, so a network attached device is ideal. The device must support alarms, via a number of different methods like email or SMS. You should be able to set the system up and then be alerted when something is wrong.

Benefits of Server Virtualization

       Server individualization is the concept of treating a physical server as multiple logical servers. How does that help? Let’s have a look.

       Virtual servers reduce your costs. Virtualization causes you to buy less hardware thereby saving you money. Also the operating costs are reduced with virtualization.

       Virtualization makes the servers stable and reduces downtimes considerably thereby making servers and the websites hosted on them available at all times. It ensures high availability and delivers prompt disaster recovery thereby offering you business continuity.

       Virtualization of servers lets you utilize the resources to the fullest. With automation and better utilization of available resources, virtualization increases the efficiency of the server. 

       In virtualization, a physical server is partitioned into multiple logicals and these logicals are independent of one another. As they don’t interfere with others, they promise increased security. This is the reason virtual private servers are often used as sandboxes or honeypots. 

       Another benefit of server virtualization is that it helps save space in your data centers as the number of physical servers is much less than the number of servers that are being used. 

      If we had to list them, what are the top benefits of server virtualization? Here's devided by categories: 

Financial benefits of server virtualization

• Reduction of HW maintenance costs 
• Reduction of LAN/SAN costs
• Reduction of floor spaces costs
• Reduction of power consumption costs

Intangible benefits of server virtualization

• Increased flexibility
• Increased availability
• Increased uptime
• Green IT
• Improved test processes
• Virtual labs
• Allow us to move to the cloud

       Have you experienced virtual servers yet? How has the experience been? Share us when and how you have used virtual servers.

Benefits of Network Diagram

       A network diagram is essentially a flow chart that includes all of the project elements and how they relate to one another. It is widely used because it is easy to read and not only depicts the sequence of activities in the project, but also shows parallel activities and the links between each activity. Network logic is the collection of activity dependencies that make up a network diagram for a particular project. In other words, certain tasks are dependent on one another to complete the project. This creates a logical stream of events that will lead to completion of the project.


The network diagram lets know the following:

• It is easy to identify the problem that come from the workstation, LAN, WAN, server or application server.
• A network diagram gives a bird-eyes view of a system without having to go into technical details. If well done it will also show who is responsible for which parts.
• Helps us find our critical / non-critical activities. So if we know our critical activities we would like to allocate our critical people on the critical task and medium performing people on the non-critical activities. 
• This also helps us to identify which activities we can run in parallel, thus reducing the total project time.
• Finally, it gives the Project Manager and the team a point of contact; the person capable of creating the network diagram surely has a thorough understating of the system.

The following diagram shown the physical connectivity between the device:
