One of the hottest technology trends among businesses and IT departments has been server virtualization. The common reason for server virtualization is to get better utilization of your servers, high availability and possibly cost savings.
Here are a few tips on server virtualization for small to medium businesses:
You do not need to virtualize everything at once – It is tempting to virtualize everything at one time, a better approach might be to pick a server that might need an upgrade such as an aging file server or email server and start to develop a plan.
Make sure your application is compatible– Not all applications are compatible or supported with virtualization. You do not want to move an application that is not compatible or supported, It could cause you to lose support from your vendor and could cause downtime
Make sure you Pick a Good SAN – Storage has come down in price, but you still need a SAN that is supported by your virtualization vendor and also has support for SNAPSHOT’s. SNAPSHOT’s allow you to make a copy of your data and store it on the SAN. SAN’s with newer technology can keep up to 900 snapshots.
Make sure you work with Virtualization Specialist – You want to make sure that pick someone who has competed this work before. A temptation exists to attempt to do this sort of project by yourself, but a big risk exists where you could mess up
Make sure you have backups – Some people think that with virtualization, you do not need backups. You do, make sure that your existing backup solution will support backing up the virtual servers.
Microsoft has released Exchange 2013, but before you rush to upgrade you have a few things to consider.
The first thing to consider is as of this date in March, Exchange 2013 is not backwards compatible to Exchange 2007 or Exchange 2010. That means it can only be installed in brand new environment. A service release upgrade is coming that will allow for migrations.
The second item that you need to consider is native RPC is gone. The only way to connect to Exchange 2013 is over http. They did this to allow for Exchange to better keep track of connections and for a better experience with load balancers. You also do not have to worry about a using a fully qualified domain name as its endpoint. Exchange 2013 uses a mailbox GUID and a UPN suffix for its endpoint.
The other change you need to consider is connecting programs such as Good and also Blackberry enterprise. They typically use what is called MAPI CDO. With exchange 2013 you will need a MAPI CDO that supports the RPC over http, which is currently not released. This is also the last release that will support a MAPI/CDO.
Finally, the roles have changed once again. You have only two roles. A Client access (CAS) role and a mailbox role. The CAS role is just a proxy to the mailbox server for both client requests and also for SMTP.
Before jumping into Exchange 2013, make sure that you consider the changes.

Final Thoughts – Wireless Networks
With the number of devices that are becoming WIFI enabled, wireless is going to become more important in the coming years. The question is: have you planned for an explosion of wireless devices? Everything from tablets to TV’s are WIFI enabled these days and are requiring more bandwidth. If you are planning for BYOD, you will need to ensure that you are covering your needs.
The first item is to review is your existing wireless solution and see if it will be compatible with some of the newer devices. Your wireless network should be at least 802.11 G capable. You should also make sure that if you are using a controller based environment, your controller will support an upgrade to the most current version.
If you have clients that are configured with WEP or with 802.11b, you need to get rid of the 802.11 b clients and also disable WEP. Why, because both will affect the performance of your wireless networks.
These just a few of the many things to consider. If you are going to experience a device explosion, feel free to contact me at email@example.com or at 262-373-9070
