Micro-soft, since 1975

Read Wired.com? Today their “this day in tech” is about Microsoft. Apparently Bill and Paul formed their partnership on the 4:th of April, 1975. I was one year old back then.

You’ll find the story here: http://www.wired.com/science/discoveries/news/2008/04/dayintech_0404

I can also recommend the book Accidental Empires, on the same subject Рhttp://www.amazon.com/Accidental-Empires-Silicon-Millions-Competition/dp/0887308554/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1207291860&sr=8-1

 

Server Core Cluster – How it's done

Having received a bunch of emails (what’s wrong with the comment-section?) about the failover-cluster construction, I’ve decided to explain it in a little bit more detail.

The basic network layout looks something like this


¬
After that setup in Hyper-V I installed Starwind from Rocketdivision which lets my Windows Server 2008 act as an iSCSI-target for the other machines. I created two disks and connected to these with the ISCSICLI on Server Core making the connections persistent. You’ll need to enable shared access for clustering to work.

The commands used are:

Starting the service:
sc config msiSCSI start= auto (note the space)
net start msiSCSI

Connecting the disks:
iSCSIcli QAddTargetPortal [Portal IP Address]
iSCSIcli ListTargets
iSCSIcli QloginTarget [Target Name]
iSCSIcli PersistentLoginTarget [Target Name] T * * * * * * * * * * * * * * * 0
iSCSIcli ListPersistentTargets
iSCSIcli ReportTargetMappings

If you know the names of the disks you can skip adding the target portal and listing the disks. You might need to add each server to the initiator list and if you’re adding authentication you’ll need to logon. (My example doesn’t use that yet, hence I haven’t tried it)

Once the disks are connected to one server you can either connect to the VDS with the MMC (just make sure the firewall is open on both servers for it to work) or configure the disk with diskpart from command-line.

And here’s the movie with the result:
