Microsoft is calling: You’re computer is having problems! (Phone scam)

Marco DrostComments Off on Microsoft is calling: You’re computer is having problems! (Phone scam)

Last week my wife got a call from from a person claiming to be working for Microsoft, and apparently they are receiving reports that there is something wrong with my computer! She told them that she does not need any help because she is married to an IT guy! But today I got the call and it seems it is the same guy because of his Indian accent!  Their phone number is blocked and the person is very pushy! But I thought lets play along!

“Microsoft Guy”: are you working on your computer now?
My answer :Yes.
“Microsoft Guy”: I can see you a running Windows now!
My answer:  Yes (but this is what I was running at the moment:)

Who needs cookies (Internet privacy)

Marco DrostComments Off on Who needs cookies (Internet privacy)

Yesterday I was in discussion with a friend about internet and privacy. He has a background in software development and told me about browser fingerprints as a very good alternative to cookies.

What is browser fingerprint? Browser fingerprint is a type of tracking that may identify you far more accurately than any type of cookie and you may never know it was there!

Back-up for virtual environments (TSMVE) is still underestimated by IBM!

Marco DrostComments Off on Back-up for virtual environments (TSMVE) is still underestimated by IBM!

When you are using IBM equipment there is a big chance that you will use IBM related software to manage the environment. In a large  environment you can use IBM Tivoli Storage Manager (TSM) for Virtual Environments to make back-ups of your virtual machines. IBM says that:

Tivoli® Storage Manager software provides a wide range of storage management capabilities from a single point of control, helping companies ride the information tidal wave.

Early this year they’ve added a new product to the Tivoli Storage Manager, IBM storage management software called IBM Tivoli Storage Manager for Virtual Environments (TSMVE). This is their product for making back-ups and to recover virtual machines.

You would think that a big company like IBM jumped on the train of virtualisation when it was leaving the train station but in my opinion that’s not what they have done!

On premises DropBox

Introduction

In our private lives we are already accustomed to using cloud based file sharing. Who of us isn’t using or has tried Dropbox? Dropbox was my first cloud based file sharing solution. In the time between now and then there are many new players in town like BOX,PogoPlug and many more. Where Box stores the files in the cloud, other store the files on premise like Pogoplug (for private use).

Now a days users are using solutions like Dropbox to store company data. Who thinks this is not happening, please get out of your cave. My customers, mostly in the top fortune or government, must be aware of the risks users are taking “without” knowing what risk they are taking. Even when a user knows the risk, they are willing to take it because of the flexibility it gives them! My advice: Think like a user! In some company’s the IT departments are still saying NO to the wish of the end user. But let’s be honest, the rules within the IT department are less restricted. And the end users (especially from generation Y) are consuming IT: they are demanding this flexibility. In my opinion these days IT is controlled by our users .Don’t try to control them, work with them. Watch and learn how they like to work, this is the only way you’ll be in control.

The sky is not the limit if you cannot fly!

Marco DrostComments Off on The sky is not the limit if you cannot fly!

Often I  hear management make promises that can not be met!

Management thinks that he or she can make decisions about the service that is bean delivered without consulting the SLA or the architectural principles! Is it possible in an existing environment to set a new (higher) target without changing  the environment? If not or not necessary than we make the assumption that all mistakes are caused by people or the environment is not build against the current architectural principles!

I don’t think that it is possible to make this kind of decision without consulting the SLA or the architectural principles!

Here is a case that I see often lately!

Auto draw Visio drawing by importing Excel data

Marco DrostComments Off on Auto draw Visio drawing by importing Excel data

I was ask to make a overview to see which servers are responsible for which application. This overview is for management and must be in a drawing format and they want to have this available when they want to. This is task that can cost a lot of time just for a quick overview. So how can I make it without buying an application and with the least amount of effort? So a went looking around and found out that you can import Excel data in Visio and that Visio can make a drawing of it if you choice the right options.

In most IT environment they will keep track of servers and possible there function in some kind of format. In my case i had two options make a extraction of the vCenter data or export the SharePoint data in to Excel. The first way is pretty strait forward select the view and make a extraction by making a export. In this blog I will go and do it the ”hard” way because of the extra steps you will have to make. Some screenshots are with Dutch sorry for that!

Back-up and Recovery of Exchange 2010 with Veeam Backup & Replication version 6

Marco DrostComments Off on Back-up and Recovery of Exchange 2010 with Veeam Backup & Replication version 6

Veeam Backup & replication version 6 I finally found some time to install version 6 of Veeam Back-up and replication and I was wondering if the back-up strategy that I used for Exchange 2010 in version 5 ( see part one, part two and part three for backup and recovery )  will change in the new version. Because in the What’s new guide it says that there is a 1 click file restore but there is noting mentioned about exchange! In this post I will describe the settings for exchange 2010 within version 6 of Veeam Back-up and recovery if they are different comparing to version 5.

When Opening the new version I noticed the fist difference: The pull down menu on the left side has changed there is no restore menu this has made placed for History menu. Also the SureBackup part is gone.

Pull down menu Veeam back-up version 5                                            Pull down menu Veeam back-up version 56
Pull down menu Veeam back-up version 5          Pull down menu Veeam back-up version 6

Latency of an SQL server iSCSI vs. FC SAN?

Marco DrostComments Off on Latency of an SQL server iSCSI vs. FC SAN?

For a customer I placed a  SQL server, which has a disk size of about 900 MB, on “cheap” iSCSI SAN with a dual 10 GB link. This was not the only Virtual Machine on the iSCSI hardware there where about 13 LUN defined with each about 6 virtual machines. I “doubted” if”  this machine was a candidate for this particular iSCSI solution but measurements of the environment showed me that it was possible.

It seems to went well but after a few days I got complaining users and i saw this graph (see below) ! It seems that something has changed on January the 17th. From that day the SQL server is bean heavily loaded with import jobs that will run every night. Because the customer want to have the latest production data for testing and training the virtual machine characteristic changed dramatically du to this adjustment! Veeam monitor write latency
