If you have some archive data that you would like to copy onto a win 2012 server, but dont know how to estimate the end volume size (if VM etc). Start small - about 1/2 of the total capacity of the drive. Robocopy the data onto the drive until nearly full, manually run dedupe, wait until complete, continue robocopy, repeat and rinse. There will be occasions where you will run out of disk space at that point its time to extend your disk.

I use angry IP scanner in windows, linux has a good util for port scanning an ip range called nmap;
Grab nmap from usual repositories
sudo nmap -sP 192.168.9.0/24 (will show hosts up and resolve mac addresses to vendors)
sudo nmap -v -sT 192.168.9.0/24 (will show hosts up and the various open ports)
sudo nmap -v -sT 192.168.9.104 (will show particular host and the various open ports)

I’ve tried using a share for time machine before, but due to the nature of how time machine works it eventually consumed all the spare space that is available on that particular share.
bring on zfs quotas… (my drive on my mini mac is 100GB, so 200GB should be enough for a few variations)
zfs set quota=200G unprotected/timemachine
This adds a artificial limit to your zfs filesystem, making sure that time machine does not consume more than 200 gigabytes of space.
I’ve played with many storage technologies at home, ZFS being one of my favs when it comes to performance. But i’ve been looking for something that suits a typical home environment where power usage and capacity is usually more important than performance. Thats where UNRAID has come in…
UNRAID give me these advantages;
Sometimes you might want to run a hypervisor on a hypervisor for testing purposes…. this is how you pass through the required CPU extensions in ESXi 5.1
Remember you will also need to enable promiscuous mode on the networking side also.
http://www.virtuallyghetto.com/2012/08/how-to-enable-nested-esxi-other.html
There are some changes with Nested Virtualization in vSphere 5.1 also officially known as VHV (Virtual Hardware-Assisted Virtualization). If you are using vSphere 5.0 to run Nested ESXi or other nested Hypervisors, then please take a look at the instructions in this article. With vSphere 5.1, there have been a few minor changes to enable VHV.
- The new Virtual Hardware 9 compatibility will be required when creating your nested ESXi VM, Virtual Hardware 8 will not work if you are running ESXi 5.1 on your physical host. You will still need to enable promiscuous mode on the portgroup that will be used for your nested ESXi VM for network connectivity.
- vhv.allow = “true” is no longer valid for ESXi 5.1 to enable VHV. A new parameter has been introduced called vhv.enable = “true” that is now defined on a per VM basis to provide finer granularity of VHV support. This also allows for better portability between VMware’s hosted products such as VMware Fusion and Workstation as they also support the vhv.enable parameter.
- You can now enable VHV on a per VM basis and using the new vSphere Web Client which basically adds the vhv.enable = “true” parameter to the VM’s .VMX configuration file.
Neccesary commands to get vmware vsphere power cli scripts runnign in power cli;

There is a bug in the tg3 driver on the ESXi hosts (1gbit broadcom cards in the new hosts). If the network card is put under load and netqueue is enabled it will sometimes decide to drop all traffic. Essentially i’ve disabled netqueue and the problems have gone away…. as per this vm kb :

You might be able to do this via “host profiles” but if you do not have the licensing for it, this is the alternative. Very handy if you have over 50 or so port groups. It can be re-run to add to additional hosts as needed.
Install powercli, run the following to obtain your current list of virtual port groups off existing host;
Get-VirtualPortGroup -VirtualSwitch vSwitch0 -VMHost esx-01
Grab the output and place into CSV file or copy straght into Excel…
Very good article here - http://networkingnerd.net/2011/02/02/when-is-a-trunk-not-a-trunk/
Particuly like setting of Native vLAN and tagged networks over an HP trunk;
So, if HP refers to an uplink carrying multiple VLANs are a tagged port, then does HP have a “trunk”? In fact they do. In HPvania, a trunk is a logical construct that aggregates multiple ports into one logical link. For those of you that might be out there scratching your heads about this one, this means that when you “trunk” a group of ports on an HP switch, you are creating one LACP link from up to four individual ports. This kind of configuration should look like this:
The directory for that purpose is hidden directly in your user folder, e.g. /home/tc/.X.d Create a file in there called rdesktop and put in it a command like
while x=0 do sleep 5 /usr/local/bin/rdesktop -f 192.168.1.100 done
Remember to make file executable with chmod

Getting the KMS count up over the initial threshold is a pain when you only have one server or one workstation to start with. Typically you need at least 5 servers or 25 client machine requesting activation before it will work.
This guy here as created a nice .exe that will trick KMS into thinking it has received all the required requests…
If DNS is failing you…. You can run the following powercil script to list all IP’s to virtual machines within vmware….
$IPaddresses = @()
foreach($vm in Get-VM){ $vm.Guest.VmName | %{ $IPaddresses += $_ } $vm.Guest.IPAddress | %{ $IPaddresses += $_ } }
$IPaddresses

You’ll need these two packages installed;
SUNWdhcs, SUNWdhcm
First ensure that the DHCP service is running. Go into the “services” gui and tick the box to enable the DHCP server.
now from commandline run…
