The annual voting for the top 50 virtualization blogs for 2014 is now open. Every year Eric Siebert takes a lot of time and puts this together over at vSphere-land.

I have contributed to the voting over the years and now this year for the first time my blog is part of this great list. I encourage each of you to head over here to cast your votes again this year or for your first time. Voting is only open until 03/17/2014 so hurry up.

Hyper-V 2012R2 vs. vSphere 5.5

admin

Now that both Microsoft and VMware have officially announced the new released of their virtualization products it’s possible make an homogenous comparison between Hyper-V 2012 R2 (the fourth generation of Hyper-V) and vSphere 5.5.

VMware vSphere 5.5 introduces several news and scalability improvements, on the other side Microsoft Hyper-V 2012 R2 consolidate its features and improve what was already existing in the 2012 version, with a limited (but significant) new features. For example now, finally, some VMware old date features are mainstream also in Hyper-V, like VM hot cloning, hot disk resize (in this case also with the possibility to reduce the size).

Compare VPN tunnel types in Windows

admin

I am sure you must have experienced VPN reconnect – a new IKEv2 based VPN tunnel that is added in Windows 7 that allows automatic and seamless switchover of an active VPN connection when the underlying Internet interface (connection) changes thus maintaining application persistence.

Isn’t that COOL – like VPN user moving from Wifi to WWAN and back –  giving a true mobile connectivity to corpnet ! Yes it is…

 This means, Windows7 in-built VPN client and Windows 2008 R2 in-built VPN server (aka RRAS) supports following VPN tunnels:

  • ·        PPTP
  • ·        L2TP/IPSec
  • ·        SSTP
  • ·        VPN Reconnect (or IKEv2)

SYSVOL Folder Structure

About each folder under the SYSVOL share in Domain Controller

SYSVOL folder used to store a copy of the domain’s public files like system policies, Group Policy settings and logon/logoff scripts, which are replicated to all other domain controllers in the Active Directory domain through File Replication Services (FRS), You can find many folders inside the SYSVOL share, I would like to explore and explain each folder by how it’s used in the process of SYSVOL replication.

domain trust

trusting domain and the trusted domain

trust1

For the diagram above, we have the following summary:

When you create a trust from the Account Domain (trusted), the type of trust will be “incoming trust”.

When you create a trust from the Resource Domain (Trusting), the type of trust will be “outgoing trust”.

Remember that Direction of Trust is the opposite to Direction of Access.

vSphere 5.5 new feutures

admin

Last night , I was looking for an article that i saw an article on virtualization .  I read this article . it will be useful for you and other friends

I ‘m going to run in this version soon. And the complete results will be announced . for the full list please take a look at VMware’s document.

1. vCenter Server appliance gets bigger

For a while now VMware has offered a Linux based appliance version of the Windows based, full blown vCenter Server, but in the past the appliance’s database pretty much limited its use to the SMB space. With 5.5 the vCenter Server Appliance can now handle up to 500 hosts and 5000 Virtual Machines. For my environment I’ll still hold out until it has the capability to at least host the application portion of Update Manager (as opposed to the patch repository), but I can definitely see its use in environments with multiple vCenter servers.   Continue reading “vSphere 5.5 new feutures” →

10 Things to Know About Server Virtualization

admin

This is a guest post from David Malmborg who is working with Dell. Here are the 10 things to know about server virtualization and why your company should think about it. Recently I have shared my personal working experience on advantages of server virtualization.  The below points are similar to earlier article but with different view and explanation.  [source article]

1. Server Virtualization Closes the Gap Seen in Traditional Server Model

Traditional server model uses one piece of hardware for each server. So it will require 75 physical servers to create 75 database, application, and web servers. With server virtualization, it will only require one server and a Network Attached Storage (NAS) device to create 75 or more servers. The power of virtualization technology is enormous and theoretically it can create an endless number of virtual servers. Virtual server technology continues to improve in both functionality and scalability.   Continue reading “10 Things to Know About Server Virtualization” →

7 Advantages of Cloud Computing

admin

“Cloud computing has changed the rules of the game between the companies expanding their services using cloud computing.”

 In recent years cloud computing services has growing continuously. Google has been one of the strongest company have providing a large range of cloud services, spearheaded Gmail, and a long list of solutions around covering virtually all areas (Maps, Reader, News, storage etc.).

Microsoft , the other large consumer market, has also invested heavily in the full range of services and providing cloud computing services. Using Windows Azure, you can rapidly configure, organize and can manage applications very easily, you can run your sites, virtual machines, mobile services and other cloud services using Windows Azure.    Continue reading “7 Advantages of Cloud Computing” →
