Microsoft Storage Disk Pools and Spaces vDisk explained

This will explain Storage Pools and Spaces (vDisk) introduced in Windows Server 2012 and now better with Tiering and Cache.

This example will create a Pool with 4 HDDS and a Mirror vDisk based on these 4 disks. When the Pool is created and you start over to the vDisk the System will automatically creates two columns for the vDisk.

Each HDD will be tagged with a reserved Reservation of 256 MB. Information about the Pool and the Spaces will be placed there. The Stripe Size is 256 KB per default. The stripe width is in a two columns envrionment 2 x 256 KB = 512 KB

A Mirror is based on a minimum nuber of disks 2 and a Column to disk correlation 1 : 2 = 2 Disk per Colum = 2 Colums = 4 Disks

To check the columns settings ... please use PowerShell

Get-VirtualDisk | fl *

The expansion of a vDisk =

Add the same number of disk you started your vDisk. We started with 4 Disk that results in 2 columns means you need for every expansion 4 new disk in your pool and then you can expand the vDisk and then the LUN.

For best performance use the half the number of disks in your pool as columns size.

Do NOT use parity. It is very slow. Mirror will rock the performance tool !

Storage Pools and Spaces are built on LRC Erasure Code.

Epic Solution Fails in Project planning

During the support and implementation of many IT projects, I found the recurrent epic fails in IT projects. You should never do the following things in or before a project.

1) Plan on beta or not supported Hard / Software Features or the magic firmware that will bring the redeeming solution. This feature will never be ready when your project has to be ready. NEVER

2) Please, CIO out there, never never plan the success of your IT project on 1.0 Software or Hardware Releases. They are and will be full of unplanned behavior and bugs. Let the other guys fix the first bugs

3) Believe Marketing

4) Complex Solutions, the devil is in the detail, and will cause failures. So concentrate on "Keep it simple" (KIS) solutions. They will look simple but are mostly rock solide solutions.

5) Test phase smaller than 1 Month. No hasty reactions in IT Project they are too complex for this kind of acting. TEST TEST TEST and by the way, create a kind documentation during testing.

6) This is really old school but...you still need a test environment for your productive world where you can do Domain Controller Fire Drills and test the patch behavior from MS or your loved vendor.

7) Missing education. Imagine the following situation. The IT project will update only 2 main applications. Exchange (upgrade) and new Lync integration. This are worlds of new features, administration tasks and problems. How can you manage to learn this whole super complex new stuff ? So plan a lot of eduction during testing phase !

during searching for a small issue to network performance with my new DELL Venue Pro 8 I read some articles about this issue and my solution is:

Restart
Install KB2883200
