Microsoft has made Microsoft Office SharePoint Server 2010 BETA release available mid this month. Stay tuned for feedback and reviews of the new SharePoint Server version as we get it set up in the coming weeks.

Microsoft has opened public beta releases of Microsoft Office 2010, Microsoft SharePoint 2010, Microsoft Project 2010, and Microsoft Visio 2010. This is an important milestone as it provides system administrators with an opportunity to gain valuable hands-on experience before the products are released to manufacture later in the first half of calendar year 2010.
You can join the beta test for any of these products on Microsoft’s web site here.
If you have been testing Windows 7 for possible deployment in your environment, now is a great time to consider upgrading to Office 2010 as well. While you are at it, take a look at VMware View 4 or Citrix XenDesktop running on vSphere 4. Deploying your next new corporate desktop OS and applications on virtual desktops running in the datacenter is a non-disruptive way to roll out the latest technologies to your end-users without the need to upgrade or replace your corporate desktops.
In ESX 4, many improvements have been introduced in CPU scheduler. This includes further relaxed co-scheduling, lower lock-contention, and multi-core aware load balancing. Co-scheduling overhead has been further reduced by the accurate measurement of the co-scheduling skew, and by allowing more scheduling choices. Lower lock-contention is achieved by replacing scheduler cell-lock with finer-grained locks. By eliminating the scheduler-cell, a virtual machine can get higher aggregated cache capacity and memory bandwidth. Lastly, multi-core aware load balancing achieves high CPU utilization while minimizing the cost of migrations.
