Dell’s $67 billion acquisition of EMC is the biggest technology deal ever. This will prove to be an added advantage to Dell sales force, known for their ability to "sell ice to Eskimos”. EMC can see this as an opportunity to tap mid-market customers. As a private entity, the combined result will face a freedom from market pressures that their competitors can only dream of. The way I see this deal is, that Dell wanted a sharper set of enterprise capabilities which EMC brought to the table. Dell also gets control of VMware which is a big asset in enterprise datacenters. If all goes well and they manage it properly, Dell will become a far more credible player alongside Cisco, and HP in the enterprise space. If you look at this acquisition from another angle this looks to be a consolidation play which also makes total sense considering the overall market inactivity within the classic client-server datacenter environments.

In today’s world where massive data is created, it is important for enterprises to back- up their data else major business intelligence can be lost with no damage control in place. Change Block Tracking (CBT) is an incremental backup technology for VMware virtual machines (VMs). An incremental backup refers to the type of backup that only copies files that have changed since the previous backup. This is an interesting feature as lot of time and resources are saved by just backing up the blocks that have changed rather than every block of every VM in the infrastructure. CBT requires ESX/ESXi hosts at version 4.0 or newer, VMs at virtual hardware version 7 or newer, and that I/O operations go through the ESX/ESXi storage stack. Administrators can easily enable this feature and if any block had been changed since the last backup, CBT will tag them in a CTK file along with all its information. It provides the intelligence to the vSphere or third party backup tool to copy the changed ...
