Installing PowerCLI from PowershellGallery

This is   part 3 of Installing PowershellGet on Windows 7. This time we are going to install PowerCLI latest version from the PowerShell Gallery.

Part 2:  http://shaulov.us/2018/01/13/upgrading-powershellget-1-0-0-1-to-the-latest-version
Part 1:  http://shaulov.us/2018/01/09/installing-powershellget-windows-7/

Let’s head to PowershellGallery website, and  find the latest stable version for PowerCLI https://www.powershellgallery.com. As of today, version “7736736” is still in beta. So we are going to use “-RequiredVersion” option to download and install the previous, stable, release.

Open the Powershell with elevated ( Administrator level) privileges:

PS C:\> Save-Module -Name VMware.PowerCLI -Path c:\PSRepo -RequiredVersion 6.5.4.7155375

PS C:\> install-module -name VMware.PowerCLI

Note:  you might need to press “A” to allow install to proceed, as PSGallery might not be in your trusted list of repositories  to download and install modules from:

Ideally, you should now be able to run  any PowerCLI  cmdlet and it would work as expected.

Note: You must uninstall older ( non-PovershellGallery one) versions of the PowerCLI manually from Programs and Features, and then re-install VMware.PowerCLI via PowershellGet,  otherwise they will conflict with the new version, and it will only work partially.

Please, see a nice write-up below in case if the VMware.PowerCLI don not load automatically.

Upgrading PowershellGet 1.0.0.1 to the latest version

This is a part 2 of the getting Powershell upgraded from v2 to v5.1, and PowerShellGet and PowerCLI installed and running on a Windows 7 Pro/Ent workstation.

The latest PowerShellGet version as of today, January 2018, in the PSGallery is v1.6.0. It needs to be downloaded to local repository first before installing it.

Something to note here, NuGet package is required before continuing further, and it will be installed automatically when PowerShellGet is upgraded or downloaded.

Let’s list the Powershell modules again, and confirm that PowerShellGet 1.6.0 is available to us.

PowershellGet 1.6 installed with old version

Oops, we have got the older versions of PackageManagement and PowershellGet still there. Naturally, we need to remove the older versions at this point.

Installing PowershellGet on Windows 7

Recently, I had to re-install OS on my primary workstation at home.  And of course, I had to get PowerShellGet  working again before I could install PowerCLI, or vDocumentation modules. Naturally, it took some time to hunt down the bits and pieces on getting PowerShellGet up and running. So, this time around I have decided to document getting PowerShellGet working on Windows 7, as well as making sure that I am using the latest version of it.
Windows 7 Pro/ENT  by default comes with PowerShell v2, and doesn’t contain PowerShellGet.

All the commands are run with elevated (a.k.a administrator’s) privileges under x64 bit Powershell console.

let’s start the PowerShell console  and see currently available modules:

Help my Windows Server 2012 (2016) deduplicated drive is gone crazy (not releasing space)

I make use of deduplication feature on Windows Server 2012, and Windows Server 2016 quite extensively. And, it does wonders. Its deduplication ranges from 10% (wsus content, backup server) to upwards of 55% ( File Share servers and SCCM Distribution Points with ISOs and .wim images, as well as packages and applications).

Recently, a case was brought to my attention where a  drive with wsusContent on freshly installed Windows 2016 server has started running out of space. Initial drive size was about 100GB, and after fe Continue reading →

WSUS server serving wsusContent; local vs remote.

Ah yes, you have had enough of it. Wsus content folder keeps growing in size day by day. You have tried feeding it 20 GB, then another 50, then 100 GB. No, it won’t stop growing and keeps demanding more and more space.

No worries, there is a solution for that… Maybe… in any case as gecko says ” 15 minutes could save you 15% or more on”  of your valuable disk space on your (v)SAN storage

 

Solution 1)  Have workstation download updates from MS directly

  1.  Downside; traffic, bandwidth, time, multiple unknown variables on how long, amount of bandwidth, cost of bandwidth
  2. To Do:
    1. Set your workstations to report statistics and  detect updates to your internal SUS Server:

      detect updates and report statistics wsus
      detect updates and report statistics wsus
    2. Choose an option to “Do not store update files locally; computers install from Microsoft Update”

 

 

Solution 2) Download to sus server, only what you need

  1. Don’t download the “Express installation files”; downside is it will take longer for workstations to get the necessary updates
  2. To Do:
    1. Check mark “Download update files to this server only when updates are approved”
    2. Uncheck the “Download express installation files”

Backing-up to AWS: Basics of Storage Gateways Types

AWS ‘s Storage Gateway solutions are designed to be used as a backup destinations for your infrastructure. There are 3 types of Storage Gateway solutions offered by AWS:  File, Volume, and Tape Gateway.

Overall process is, you either deploy a local on-premises VM ( Hyper-V/Vmware VM), or a cloud based one which is in turn of course runs on AWS EC2 instance. You need to add an additional virtual disk to the  Storage Gateway,  to cache the data before it uploads it. The disk size has to be a minimum of 150GB, and you can add several drives for a total of 16 TB in size across all drives. You can’t allocate the drive with 150GB to begin with, and then increase its size down the road, you will have to add a new disk, if you want to increase the cache size.

There is an additional requirement for Volume and Tape Storage gateways; you will need to have an “Upload Buffer” drive(s) along with caching drives.  Upload buffer drive has to be a minimum of  150GB and a maximum of 2TB in size.
As name suggests, Upload buffer’s purpose is straight forward; backup data from the cache drives are transferred to the  upload buffer drive, and afterwards it gets copied to AWS’s storage, then buffer gets re-filled from the cache drive with more data, and so on.
Cache drives purposes is on the other hand is twofold;  besides pumping more data into Upload Buffer, it keeps the  cache of your most recent backup data, depending on the cache drive size. It will check the cache drive to see if the data is still available on the cache drive, if that is the case,  then  you don’t have to  pull data down from AWS storage, and of course not incurring  data transfer (charged per GB of data retrieved) charges from  AWS.

Data Storage:Compression, de-duplication or deltas ?

File based Storage gateway (NFS) doesn’t make use of any compression or de-duplication mechanisms. But as per FAQ ” uses multipart uploads and copy put, so only changed data is uploaded to S3 which can reduce data transfer”. Basically, it will compare your current file with the one that was already uploaded, and upload only changed bits, which is still good, and should reduce Continue reading →

Migrating WSUS to a new Windows 2016 server, and 2014 standalone SQL server

Plan is to retain current WSUS data and configuration while moving the SUS service from old Windows 2016 TP 5 server to an new fully licensed Windows 2016 Standard server, and move database from WID to a standalone SQL 2014 server.

1)   Setup a new Windows 2016 Server, update. Patch, reboot. Install the WSUS role on it, choose the WID database during the install. Make sure to point to a drive\folder for wsusContent.
a. Copy the wsusContent folder from old server to the new one. Make sure you placing it to the proper drive\path, you identified during post-install configuration for new WSUS service.

Teradici APEX 2800: how can I quickly confirm if the offloading works or not.

I recently got my hands on teradici’s 2800-lp (low profile) offloading card for the a Horizon view 7 VDI PoC implementation. The one I am using is a PCI Express version of the card that can be installed on any server with PCIe gen2 x4/x8 or x16 slot.

There are also MXM Type A with Mezzanine Adapter and an Amulet Hotkey DXM-A versions. They are designed for HP’s Gen8 and 9 blade servers, and for Dell M Series blades respectively. In either case, standalone, mezzanine adapter, or an amulet hot key, you can install up to 2 of such cards per server.

There are plenty of choices on the market for a GPU offloading, some of which are Nvidia’s Grid K1/K2, Nvidia Tesla K40 /K80, and AMD’s FirePro S7150 (x2) GPU cards.
