Ok we all know about virtualization at this stage and if you dont where have you been!! Smile

 

Lync 2010 is microsofts next generation voice platform with integration IM and Video Conferencing, combine this with exchange and you got your self a full phone system with voicemail and more so a unified approach (hence the unified communications piece! Smile with tongue out

now here is were it gets interesting in my view… traditionally when it comes to voice systems and especially the previous generation of the products and the current generation of exchange 2010 unified messaging they tend not to like to be virtualized. Not that they wont work in an environment that is virtualized just that the associated overhead that you naturally inherit when you virtualize a system starts to become an issue.

Also when you consider legacy PBX vendors were all hardware based, you have to stand and consider the approach of virtualizing what is considered the most important system in a company in many cases. if your phones go down it usually means bad for business, even more than if an email system goes down (there is a little tolerance for that as well but more than what is for if you phone system goes down!)

So you begin to ask yourself does it make sense and really do you want to do…..

First of all yes you can and here is a link to the best practice document from Microsoft around lync

http://www.microsoft.com/downloads/en/details.aspx?FamilyID=842F2426-AB3C-4510-9283-BFBF9D1B4438&displaylang=en

HOWEVER it should really only be considered in certain scenarios and ALWAYS ALWAYS make sure it is a very well spec’d host with plenty of overhead and very low latency components. This is simply to ensure the best user experience possible.

Now in my personal consideration it should only be used when it comes to Proof of Concept or even as a backup registrar which would make sense as if your main box goes down at least you can still work even if it is in a degraded capacity (obviously with this scenario i havent considered this to be a full enterprise deployment Smile )

if you do decide to virtualize, please ensure you perform follow all virtualization guidelines as listed in the document and review the general best practices around virtualizing SQL and Windows 2008 R2, as every point in the chain matters. Ensure your storage system is not bottle necked and that you have sufficient cpu and memory capacity to carry this load and any projected load when you design the system.

In short every company is different and some will want to ensure the system is virtualized, but ensure expectations are set, guidelines are followed and properly capacity planning is done…

As previous mentioned to numerous colleagues and various chats i have had with people, i am certainly an advocate of a virtualized world and if it can be done i generally will, but there are some workload’s out there you have to stand back from and just consider… is it really a good idea.

We all know user experience is key to adoption and provide bad user experience… well you know the answer… Open-mouthed smile

very interesting read i thnk Smile

here is the article….

Azure VM Role

this has got me really interested, after a good bit of research on how you would achieve the mechanisms to get it between on premise and the cloud, i know see this as an excellent reality. especially for the small companies who service it and want flexibility that would be outside the standard offering of office 365 (which btw does rock!)

i moved my own domain to office 365 last night and am loving it so far. just need to play with the sharepoint elements of the system….

 

but the vm role in azure has real possibilities especially as you use all the FREE tools from MS to do the provisioning (small extension pack is needed) needless to say as soon as i can get on to the relevant beta program / tap i will….. and off i go to dig Smile

 

ladies and gentlemen —> its more difficult to go against the grain and when the grain is this smooth in the this direction why bother!

the technology is here now, cloud is what our future is (until something else comes along…. Smile with tongue out)

i was pointed to this software which plugs into SCCM and allows you to manage your non windows mobile device estate from microsoft sccm 2007 r2 pretty damn cool if you ask me.

Lync

As we all know by now today was global lync launch day 🙂 and personally I think it’s such an amazing the technology has come on so much in just over the two years that I have played with it, it’s incredible.
Some of the things right out of the box that are very impressive for me are

The interface from a client and server perspective are completely different and for the better I think! Let’s just say silverlight

The second big thing for me is the virtualization standpoint. Virtualization equals less physical hardware which equals better chance of deploying lync 🙂 and let’s face it as excellent as it is lync still requires servers ( virtual/physical) one way or another and the more complex your design the more servers that are needed but I stress that it is for good reason but since you have now got good virtualization support it’s becomes easier to deploy! Just make sure you have the head room to virtualized and more so it makes sense for your deployment

The next part of lync that is just brilliant is the colocation of the mediation role on the front end server.

Media bypass, sip trunks, powershell etc… There is so much more that makes it worth looking at but the final thing I think is worth mentioning is the audio quality is at least 10 times better than OCs and with the right headsets / handsets better than traditional Pbx PERIOD

It that time again were a few of us sit down and start planning the next event… And yes this time it’s going to be bigger and even better than our last one! Multiple tracks covering many different topics…. 🙂 all will be revealed soon…

Moving Lync Eval to RTM

taken from nathans blog…. but yes it can be done…

http://nathanwinters.co.uk/2010/11/11/moving-from-lync-eval-to-real-rtm-volume-licensed/

 

Hi,

This has been coming up a few times in recent days on forums and distribution lists.

The question is can I install Lync Eval now, and then transfer to full Volume Licensed RTM code when it is available.

Well yes you can and it is supported.

Here’s how:

After you get access to volume bits  through a normal sources like the volume license site:

On every machine which has EVAL version of Server.MSI installed: 

1. run "msiexec.exe /fvomus server.msi EVALTOFULL=1 /qb (Note: the server.msi is from Volume media)

2. run PS cmdlet "enable-cscomputer"

Hope that helps

Cheers

Nathan
