HP T200 vs Axel M80 WMS Client trial

We’ve recently installed some HP T200 zero clients with an HP Z210 acting as the host.

Axel were also kind enough to send me one of their M80 thin clients to test against as a comparison.

This is not a scientific test but my observations.

The T200’s work by encapsulating USB over Ethernet to communicate with the hosts and this is quite compute intensive which is going to limit the number of clients you can connect.

The M80 on the other hand is an RDP client and it will scale to larger numbers of client on the same hardware, Matthew Stones from Axel also sent me over the WMS firmware for the M80 which turns it into a dedicated WMS client and restricts it to only connecting to a multipoint server.

Installing the firmware on the M80 was a breeze basically consisting of installing the Axel management utility discovering the device and pushing the firmware to it. Matthew linked me to one of his youtube videos that demonstrated the process.

The biggest test for both these devices seems to be the playback of flash video and I tested each one with a windowed youtube clip of an F1 car, the thinking being that it’s fast moving video with sound and on board graphics that help check if everything is in sync.

Both devices played back the video well however I think that if connecting a lot of clients to a multipoint server that the M80 WMS is going to scale better and at the moment it’s what I would recommend.

The T200’s due to their lower cost however are ideal for smaller clusters but they are also a new product and their has been at least one driver/firmware update since their release and the updating process is a bit slow.

With 8 users connected via T200’s I was seeing a memory usage of 3.5GB and networking at around 99%

Dynamic Distribution Groups

Wouldn’t it be nice to have email distribution groups that automatically change themselves to reflect changes within your organisation?

With [email protected] ‘s Dynamic Distribution Groups, DDG, that is now possible.

The functionality for creating these is not exposed through the web interface so you do have to get stuck into PowerShell.

First of all you need to connect to your tenant:

Open a PowerShell command window and use the following code this will prompt you with a pop-up to enter the required credentials and then log you in.

$Cred = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $Cred -Authentication Basic –AllowRedirection
Import-PSSession $Session

Once you are connected issue the following command to create a DDG:

New-DynamicDistributionGroup -Name “All Foo Staff” -RecipientFilter {(RecipientType -eq ‘UserMailbox’) -and (Company -like ‘Foo Company’)}

Now when you send an email and the “To” field contains “All Foo Staff” and email will be sent to everyone who’s Company field is populated with “Foo Company”

If you want to display the current members who match this DDG use:

$AllFooStaffDDG = Get-DynamicDistributionGroup “All Foo Staff”
Get-Recipient -RecipientPreviewFilter $AllFooStaffDDG.RecipientFilter -OrganizationalUnit $AllFooStaffDDG.OrganizationalUnit

Disconnect from your tenant:

get-PSSession | remove-PSSession

Some websites to help you with this:

Due to the fact that the DDG is evaluated everytime it’s run any new member of staff that is added to the companies [email protected] tenant will be automatically included in the DDG if their attributes, in this case company field, matches.
