What will be Future Technologies?

The following technologies can be future technologies, just a prediction:

1. Virtualization
2. Cloud Computing
3. GIS

Virtualization:
Considering current economic turmoil, many of organization no more willing to invest money for their IT infrastructure. CTO/CIOs would consider more ROI than TCOs of their IT infrastructure. By virtualizing their IT environment, they can make more ROI.Currently, IT companies are doing research projects and grooming up their human resources to compete in the post-recession periods.Therefore, they would prefer to virtualize their systems to cut down cost for Desktops/servers. When a research project needs around 40 systemsfor the entire organization, they can simply go ahead with one higher class server such as DELL PE 2950/R905 and load the VMWare/XenServerfree Hypervisor and have 40 systems. Now, the ratio became 1:40. They really going to cutdown additional 39 physical servers and HVAC costs.

Cloud Computing:
Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports themThe concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent technology trends which have the common theme of reliance on the Internet for satisfying the computing needs of the users. Examples of SaaS vendors include Salesforce.com and Google Apps which provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers.

GIS:
Any developing nation needs GIS related projects soon. Govt. of India, having some million dollar worth of projects for GIS.One question remains that who is going to wake up the government for those GIS related projects. State goverment can manage their land/facility management using some GIS software. Any nation's Border force also can have GIS to survilleance their Border, restricted zones such as Atomic Center/Power Station. Also, there are lot of opensource GIS products which can facilate the requirment. In India, stree level map is not that much accruate/sublevels. Some areas of GIS such as LandParcelling,GeoIntelligence and Image processing will have tremendous growth in near future.

vCenter Reinstallation after 60-Days trial expires without losing Database Contents

Many of us still evaluating the vSphere and vCenter in our test environments. Sometimes, it takes more than 60 days to evaluate where trial edition expires.
We can't extend the trial edition in ESX host, either we have to reinstall it or license it. vCenter also have to follow the same way as ESX does. But, here we can keep old database contents as it is when you reinstall the vCenter software.

This document using vCenter 4.0 and SQLEXPRESS 2005 (built in) database. At the time of installation of vCenter 4.0, it installs SQLEXPRESS 2005 by default unless any other Database specified. Mostly, we are using built-in database is SQLEXPRESS 2005 for testing environment.
When you install vCenter 4.0, it installs SQLEXPRESS 2005 and creates a database called "SQLEXP_VIM". You can view this thru SQL Server Configuration Manager console.

Set VLAN ID to IPMI Address in Nutanix

The IPMI is remote management interface like as HP iLO, DELL DRAC. During the Nutanix cluster deployment, it is not possible to mention the VLAN ID of the IPMI's IP Address. This need to be entered thru command line via ESXi host or Windows Hyper-V. This article talks about ESXi host only.

Login to ESXi thru SSH client. Run the following command to enter the VLAN ID (we assume that you already configured IP Address)

~ # /ipmitool lan set 1 vlan id 333

~ # /ipmitool lan print1
Set in Progress         : Set Complete Auth Type Support       : NONE MD2 MD5 PASSWORD  Auth Type Enable        : Callback : MD2 MD5 PASSWORD                          : User     : MD2 MD5 PASSWORD                          : Operator : MD2 MD5 PASSWORD                          : Admin    : MD2 MD5 PASSWORD                          : OEM      : MD2 MD5 PASSWORD  IP Address Source       : Static Address IP Address              : xx.xx.xx.xx Subnet Mask             : 255.255.254.0 MAC Address             : xx:xx:xx…

Changing Thin to Thick disk and vice-versa

You can change the existing Virtual Hard disks (VMware based) from Thick to thin and vice-versa. This can be achieved by either using VMotion/SVMotion or command line tool called "vmkfstools". Using VMotion/SVMotion is required a valid license. Select “Migrate” and choose “Change Datastore” and select the Disk format.

If you don’t have a VMotion/SVMotion license, use the following command to achieve the same.

From Thick to Thin:

vmkfstools –i "Thickdisk.vmdk" -d thin "Thindisk.vmdk"

It will start to clone to virtual hard disk in Thin Provision method. After completed, you can attach this disk with VM and power it on. If all looks good, you can delete the original thick disk from the data store.

Use the following command to see real-time usage of thin disk:

du –h "Thindisk.vmdk"

You can notice the big difference of disk usage between of Thin and Thick format disks.

From Thin to Thick:

vmkfstools –i "Thindisk.vmdk" -d zeroedthick "Thindisk…
