This is inspired by a post on my Google+ stream from Pasi Ääpälä.  I just wanted to create a quick demonstration video on how to save/redirect command output to the clipboard in Windows.

There is an article outlining how to help increase stability of your Chrome browser by making plugins Click to Play. This is good and dandy but what I’ve seen is that even after you allow a plugin (flash player in this case) to run, it remains loaded after you navigate away from the page or close the tab.

Here is a video demonstration of the process I use to enable Click to Play and show what is happening.

SFTP Net Drive lets you create a virtual drive on your local computer that will expose the remote file system accessible via SFTP protocol.

I have found this tool invaluable. It comes in handy when you want to work on development remotely and don’t want the hassle of setting up SAMBA between your mixed Linux/Windows environment.  Oh, and it’s FREE.  =)

SFTP Net Drive for:

  • Windows XP
  • 2003 Server
  • Vista
  • 2008 Server
  • Windows 7
  • 2008 Server R2

32-bit and 64-bit platforms are supported.

[stextbox id=info]Note:
Remote Server Administration Tools for Windows 7 with SP1 can be installed ONLY on computers that are running the Enterprise, Professional, or Ultimate editions of Windows 7 or Windows 7 with SP1.[/stextbox]

I like to manage as much as possible from my workstation.  One thing I am constantly working with is ActiveDirectory.  Windows 7 does not have this feature natively, so you must download and install it then enable the feature.

Download RSAT for Windows 7

Step 1: Download Remote Server Administration Tools for Windows 7 with Service Pack 1 (SP1)

Install RSAT (Download from Step 1)

Please install RSAT from Step 1

Enable Feature AD DS and AD LDS Tools

Here you will enable specific features of AD DS and AD LDS tools.

After features installed, look in Start -> Programs -> Administrative Tools for the newly installed RSAT tools.

I’m working on an Excel spreadsheet (cheatsheet) that will allow for user input to calculate some of the following:

  • Calculate IOPS, Usable Space, MB/s  based on Number of Disks, Spindle Speed, RAID type and Read/Write Percentages.
  • Calculate Number of Disks required for IOPs
  • Calculate/Convert MB/s to IOPS
  • Calculate/Convert IOPS to MB/s

It also contains some basic information and formulas:

  • Formula for Total Raw IOPS
  • Formula for Functional IOPS
  • Formula for MB/s from IOPS
  • Formula for IOPS from MB/s
  • Formula to determine number disks required for IOPs based on RAID type and spindle speed.

Here’s a screenshot:

RAID/IOPS Calculator Cheat Sheet
RAID/IOPS Calculator Cheat Sheet

Here are some of the formulas used:

  • Total Raw IOPS = Disk Speed IOPS * Number of Disks
  • Functional IOPS = (((Total Raw IOPS*Write%))/(RAID Penalty))+(Total Raw IOPS*Read%)
  • MB/s = (IOPS * KB per IO) / 1024
  • IOPS=(MBps Throughput / KB per IO) * 1024
  • Formula to determine disks required for IOPs (total required IOPS * read%) + (total required IOPS * write% * RAID penalty) = total IOPS required take that and divide by IOPS provided by disk type (15k=175, 10k=125, etc.)
