Useful applications for VMware environments

Posted by Xaus Xavier Nadal 12th on May 2013

Today we are going to show several useful applications for VMware, these apps are free and do not require much knowledge to use.

Some of them are quite powerful and as you will see are continuing to substitute existing VMware environments in applications, but in some cases improved by the community. It's amazing what programmers can do with a good base of knowledge and with your imagination.

UBERAlign, IOMETER, and ESXI-customizer

UBERAlign

And finally, the best of 3, UBERAlign is a Windows application by or through an appliance (OVA) allows us to align Vmware vmdk disks of virtual machines with disk array which is mounted and the system vmfs windows for example.

 

2 consists of parts, the client and the virtual machine..

 

In the case of creating vmdk disks using the Virtual Center problem in the vmdk not exist, but instead of mounting windows 7 or Windows Server 2008 assemble an older operating system the vmfs system will not be properly aligned and have the possibility of increasing the disk performance if we use this tool.

 

They say that we can expect to earn between 9 13% and performance in virtual infrastructure.

 

With UBERAlign we can first diagnose whether we have a failure of alignment and then resolve it if you think fit.

 

But this tool goes further, also achieved if we needed reclaim space that we are not using in virtual machines and after transforming discs to thin to have this space on LUN to accommodate more machines, you can see in the following video .

Until you takes a snapshot of the virtual machine if there is a problem in the process.

 

If you want to see why it is important to explain the alignment you perfectly in the following link: http://www.blueshiftblog.com/?p=300

 

You can see more advanced information on the following link http://nickapedia.com/2011/11/07/for-advanced-users-uberalign-api-cli-powershell/

IOMETER

The first application we show is Iometer which you can download from the following link: http://www.iometer.org/doc/downloads.htmlThis application is open source and is not only useful for VMware environments, but for environments where we have a SAN, NAS, iSCSI, or even local disks back to store our data, computers or servers, this app serves as you said the word to measure disk IOPs we want, but we can also see the response times and MBs per second and other data.

 

When running the application will allow us to select the disks we want or even access to network drives by 5 top menu icon.

Update management agents on DELL servers

Posted by jl on January 16th 2012

Hello everyone

In this post we will see how to install / upgrade the management agent with DELL computers, called the Dell OpenManage Server Administrator Managed Node.

The first is to unburden the dell support page www.dell.com / support the appropriate file for your operating system. Specifically we've fallen for a W2003 VMWARE ESX server and 4.1:

  • For a machine W2003 the file is a exe file is decompressed and then we run the setup.exe file, located in c: \ OpenManage \ windows \ We see the following screen to see if we meet the software requirements and if not There is no error message click on the button Server administrator and we start the installation with the default settings.

As expand the disk size of a virtual machine

Posted by jl on November 9 2011th

Hello everyone

Following my last post where we talked about an appliance that allows us to manage the virtual infrastructure from a mobile device, today I will introduce a tool that IMHO is essential to know when managing virtual infrastructures. It's called EXPART and allows us to increase the size of the hard disks of virtual machines with Microsoft operating systems.

This is a tool that can Dell and downloaded from this link http://support.dell.com/support/downloads/download.aspx?c=us&cs=19&l=en&s=dhs&releaseid=R64398&formatcnt=2&fileid=83929

Let's get in position, imagine you have a virtual server, which initially will have assigned a virtual hard disk size, and for whatever situation we are too small and you need to raise your size. Let's see the different steps to do: Megacrack read »

Ajenti Installing Ubuntu Server LTS 10.04

Posted by drakkonian on September 19th 2011

I made an installation of the application Linux server management Ajenti in a Ubuntu LTS Server 10.04 and we summarize here the steps followed:

  • File Backup / Etc / apt / sources.list with the command: sudo cp / etc / apt / sources.list / etc / apt / sources.list.bak

Ajanti_1

  • We check for file existence / Etc / apt / sources.list.bak as a mere formality with the command: l / etc / apt , We know that Linux does not fail XD

Ajanti_2

  • Modify the file sources.list adding the entry deb http://repo.ajenti.org/debian main mainIn my case I used nano to make the change:

Ajanti_3

Check your best DNS server (Fast and nearby)

Posted by Xaus Xavier Nadal 28th on August 2011

Good,

Today I show an open source application extremely useful for improving code performance servers DNS Local and improve the performance of DNS queries to the internet by releasing internal DNS load and speeding the delivery of responses from the DNS to our computer, server or network.

The idea is to detect what is the fastest DNS, with better response time and closest possible through an application developed to make a series of performance tests to detect internet which is the best DNS for our teams.

At home it is very simple, run the program, collect data and modified your router or in your local area IP of the DNS assigned to your teams that indicates the program.

In a company you will have to run the program from all points with access to internet, ie if disponéis proxy server you should run the program from each delegation / site with direct access to the Internet and every ISP and geographical location has closest DNS servers and faster than others, so if a company has contracted an internet line with Telefónica and another is with Telmex, Axtel, at & t, etc ... should run the program in each of these outputs to the internet with a computer that has access via those networks.

The program can download it from the following link:
