Everyone knows the benefits of using virtualized environments. However, as with using any new technology, there can be some growing pains and problems. This may require you to change your processes, or perhaps use some new tools. Whatever the case may be, using virtualization will prove beneficial once you are able to work the kinks out.
Performance Problems:
Switching to virtual network environments over traditional ones should be a straightforward process. Unfortunately, sometimes these changes can lead to network performance issues. This can be caused by virtual machines requiring more of your traffic utilization than expected. One way to avoid this problem is to leverage a network management solution so you can configure your system better. “
VM Sprawl
” VM Sprawl occurs when you are adding so many new virtual machines that perform very specific tasks you start to realize that you are quickly consuming all your IP addresses. As if managing IP addresses in a traditional system were not difficult enough, now you have virtual systems hogging up IP addresses. This makes the old fashioned way of address management in a spreadsheet obsolete. If you aren’t yet using an address management tool that actively helps your IP address space, you should start now.
Network Congestion
This is something that happens in every network, but when your VMs are dependent on having a certain degree of latency, you can start to have some problems until you can fix this. The best thing to do in this situation is to get on top of your NetFlow analysis. You may be surprised to find out that it is you’re VMs that are actually causing the problems.
Application Performance
is Lagging There are headaches that may occur when migrating over to VMs and that is no joke. You may discover that the application performance that you previously enjoyed somehow acts differently once it is put on a VM. This happens from time to time, and the best way to overcome this is to be using application performance monitoring to keep an eye on what is going on, as well as alerting you when things get really bad. Taking a proactive approach to this it the best way to get one top of whatever issues there may be.
Storage Allocation
When you move things to VMs, you have many environments that are taking resources from your SAN, more so than ever before. Because of this, your users may start to see some serious problems with storage. They’ll simply thing there is something wrong with the server when in reality the problem is that you’ve got dozens of VMs taking resources from your SAN. With this type of issue, it is best to go in and use some tools to allocate resources better for each environment, if you aren’t doing so already. Using the right tools for virtualization is key as VMs can save you on hardware costs, time and other benefits, but the reality is that you’ve got to stay on top of what is going on very closely to make everything seamless on your network in order to make virtualizing your system components successful.
