Manage an HP Smart Array directly from VMware ESXi

In my lab I’m using a Proliant DL380 G5 filled with disk as a storage server, running some VSA on top of the volume I created  and formatted with a vmfs filesystem. From here, let the fun begin! There are many commands you can run on the raid controller by running /opt/hp/hpacucli/bin/hpacucli, I’m going to show you some of them: First, I identified the controller. Remember is in slot 3, this will be needed in the next commands. As I said, my problem seemed to be related to the cache battery, so I went to check its status: The status seems to be ok, but I went to enable anyway the cache, the command is: 1ctrl slot=3 modify dwc=enable

PXE boost SCCM 2012

PXE booting during a OS Deployment with ConfigMgr 2012 can be a bit slow on a Windows 2008 R2 / 2012 server. This is because Microsoft has set values that will suite most network environments. But I want SPEED. Now what? Good news. You can tweak your PXE-enabled Distribution Point! Add a registry key: HLKM\SOFTWARE\Microsoft\SMS\DP\RamDiskTFTPBlockSize With a REG_DWORD value of MAX 4000 Hex!! Then restart the WDS Service. I set this value to 2000 Hex and speed is blazing fast!
Remember the higher value the more risk of packet loss if you have a bad network connection.
Try this out carefully in your network environment.
If you experience problems, lower the value.
