Many of you may had experienced that the new vSphere vCenter client may not work properly on Microsoft Windows 7. To overcome this, some of you may require to install the vSphere client on a virtual machine which run on Windows XP.

Posted on May 25th, 2009 in Server, Storage, Tips, Virtualization, vSphere | 10 Comments »

With the recent experience I had on the deployment with vSphere 4 and PowerVault MD3000i, I found there are plenty of room you may able to further fine tune to improve the performance of the storage and virtual infrastructure. Before this, the initial deployment was done by default configuration without any fine tune yet, and I found that the storage performance looks  little bit slow. Therefore, I had decided to further research and fine tune everything we had to improve the performance.

Equipment List

  1. 2 x R710 with Intel 5530
  2. 2 x PowerConnect 5424
  3. MD3000i with 15 SATA Disks
  4. Software ISCSI initiator from vSphere 4

Posted on May 23rd, 2009 in Tips, vCenter, Virtualization, vSphere | 1 Comment »

Many of you may had noticed the changes in vSphere 4 if you had previously implemented or managed any of the virtual environment running vmware infrastructure. VMware had converted every license file we previously own to a new license key which allow us to apply to the vSphere hosts we had in our environment. If you had sign up the SNS previously, you will be entitled for an upgrade and under the license portal of your official log in ID that previously register with the license you bought, you will notice the new licenses key provided once you log on. Generally, the way of managing the CPU licenses will no longer be the previos method as we did in ESX 3.5.

If you are running RC now, you may not able to manage the official release vSphere 4 host by RC version of vCenter you had. I reinstall fresh for my vCenter 4 on Windows 2003. Since is a test lab, I do not build the DB on SQL Server as I did for production. I am using the default sql express as part of the installation.The installation process will not be much different compare to RC, but the resource utilization of the vCenter 4 will make the different.
