Processors, graphics cards, solid state drives and much more is all in this section of the site!
Work is coming along nicely with the Server Room, we’ve now removed the last Cisco switch from our infrastructure and the HP 5400R series switch is deployed replacing the 2530 that was in its place; over time we’ll be bringing more fibre from our edge switches into this room as well hence the number of SFP+ ports on the 5400R. The entire front of the cabinet is now populated with hardware or a blanking panel as well (panels available from Comms Express) to keep things looking tidy. I wish there were a little more that I could do with the cables coming into the 5400R however with a very narrow rack there’s not much that can be done.
Some interesting things have come out of both Rucks and PaloAlto recently in that they offer Hyper-V compatible VMs for their services which could free up a further 3U of space and remove a further 4-6 cables out of the picture.
Looking for some fun ways to get more out of your your Smart Card deployment? If so have you tried……?
- Use Smart Cards to login to your Servers via Remote Desktop
- Use Smart Cards with the PowerShell Get-Credential Commandlet
- Use Smart Cards with your Firewall for single sign on
- Use Smart Cards to login to IIS Web Applications (just a box to tick and a radio option to select)
- Store multiple identities on your Smart Card and assign different (and perhaps more complex) PINs to the identities
Have a look at the screen shots below for some more details…
If you are looking for a free tool to manage some of the more intricate features of the Gemalto IDPrime .NET and MD cards then the Mini-Driver Manager (downloadable from http://www.gemalto.com/products/dotnet_card/resources/development.html) may well fit the bill. However it has one small downfall in that out of the box it only allows you to manage cards with the Admin Key set to 48 0s or 48 Fs with neither option being much use to anyone once they have changed the Admin PIN.
Luckily these values are only set in a INI file so its pretty easy to change them to anything else.
Please note that this guide uses a feature in Notepad++ to elevate an application to have local Admin access, you can download Notepad++ from https://notepad-plus-plus.org however you could also use plain old Notepad you’ll just need to launch it as an Administrator and browse to the INI file within Notepad.
On with the guide!!
So after meaning to play with Smart Cards in greater detail for some time we’ve just received a set of cards and accessories from Smartcard Focus (http://www.smartcardfocus.com/) including….
- Gemalto GemPC Shell Token V2 (IDBridge K30) (a USB dongle style Smart Card reader which you can see in the screen shot sequence below)
- Gemalto IDPrime .NET smartcard – SIM cut (to go in the IDBridge K30)
- Gemalto IDPrime .NET card – just your standard Smart Card
- Omnikey 3121 – just your standard Smart Card reader
One of the first things I wanted to do was get PIN complexity and policy defined; the chaps over at Gemalto provide a number of tools which can be used to manage the cards which can be downloaded from the links below…
So time to get on with the guide (which also shows you which downloads are needed from the links)!
48 0s typed out… 🙂
Is the desktop dead yet? Well with the 4th Gen Lenovo X1 Carbon (i5-6300U/8GB/256GB) and the ThinkPad OneLink+ Dock it might as well be! This powerful little dock has just a single cable to plug into your laptop which provides power and connectivity to the dock.
For connectivity the dock includes
- On the front…
- Stereo/microphone audio combo port on the front
- 2x USB 3.0 ports on the front one of which is ‘always on’ powered – great for charging up your phone
- On the back…
- 2x USB 2.0 ports (or as I now call them ‘Keyboard and Mouse ports’)
- 2x USB 3.0 ports
- 1x Gig Ethernet port
- 1x VGA port
- 2x (full sized) Display Port 1.2 ports
- Cable to your laptop
- On the side…
- Kensington cable lock
Going by the Lenovo website (Super long Lenovo link) this dock will work with the ThinkPad X1 Tablet, ThinkPad P40 Yoga, ThinkPad Yoga 14, ThinkPad Yoga 260, ThinkPad Yoga 460, X1 Carbon (4th gen), X1 Yoga.
Some super awesome little features that have really helped
- Power on button for the laptop on the dock – even with the screen closed it’ll power on your laptop (just too bad with the screen closed I can’t get to the fingerprint reader!)
- With the Ethernet cable plugged into the docking station the laptop will turn off its WiFi
- The docking station comes with a power cable (thus you don’t have to sacrifice your laptops power cable or buy an additional one!)
- Even though only one of the front ports is ‘always on’ powered the second port has no issues in powering up and running a 500GB Freecom USB Hard Disk Drive.
So as you will have seen from the photos this screen has no issue in running 3x screens; but what about 3x screens while running a video on each screen, hammering the USB 3.0 port on the front running Crystal Disk Mark to a USB HDD, with audio streaming and my phone on charge? I certainly couldn’t notice any issue and the CPU on the X1 stayed below 22% through the test.
In the past I’ve seen docks like these kick out a fair amount of heat (when under load in particular) and while you can feel some heat from the OneLink+ dock it really isn’t much at all (only a few more degrees Celsius above its ‘off state’). In addition some laptops seem to ramp up their internal fan when attached to a dock – in this case the X1 Carbon behaves and under ‘productivity tasks’ I couldn’t notice the fan noise at all.
I would prefer to see the VGA port replaced with a further display port (on high resolution screens VGA really does not work well) the Lenovo ThinkPad OneLink+ Dock really is an excellent bit of kit; not once have I looked back on my desktop and having extra desk space is just an added bonus.
Having recently purchased a Dell T430 tower server which we will be using for backup and Hyper-V replica I thought I’d share some photos of what the castors (an option in place of either the rack mounting kit or the floor stand feet) look like!
The castor assembly comes in a separate box to the server and only takes a minute or two to install; I perhaps was expecting slightly larger wheels however they do a good job all the same on hard floors.
The screenshot above shows a portion of the sensor in its default form; in this post I’m going to show how to…
- Remove the red ‘downtime’ line from the bottom of the chart
- Set maximum and minimum values of the graph to display 0 to 100%
- Set the gauge to display its value in GByte instead of MByte
Red Downtime line
Pure aesthetics with this tweak – the memory sensor isn’t something that I would expect to ever encounter downtime (if there server were offline then the PING sensor would pause the memory sensor automatically). The only real application for the downtime sensor would be if WMI wasn’t responding.
Max and Min
PRTG will automatically set the scale for your graphs but I prefer to see the full range of 0 – 100%; this tweak makes that possible.
GByte instead of MByte
When working with servers with small amounts of RAM (lets say 4GB and less) it is typically going to work out best to view free RAM as MBytes but when working with Hyper-V hosts (48GB and 96GB in my case) GBytes are a much better value to work with.
The end result…
Its been a day or so since buying a Microsoft Band 2 (took a while to find a high street shop that had one to try on in the first place!) and its proving rather useful to me as a person who rarely has his phone turned on loud and really never notices the little vibrations from it. My most recent application of Band 2 has been using it to receive push notifications from PRTG via my Windows Phone.
In all truth if you already have push notifications setup then you are probably already getting the notifications however if you are not keep reading to find out where to check for the right settings…
On the Microsoft Health App/Band Tiles
On the PRTG App
On your PRTG Console
On your Notification Settings
With the front to back patch panel installed and T430s rack mounted the server room is coming along quite nicely. Next up will be a tidy up of the cables at the back of the rack bringing all of the power cables to one side and the network cables to the other. Stay tuned for more in the coming weeks!
As part of an ongoing project to improve the room today we’ve been installing a set of rails for a pair of Dell PowerEdge T430 servers. You may have noticed the ‘T’ in the T430 to indicate they are tower servers but Dell provides a 5U rack conversion kit which is pretty easy to install.
One small question came up while putting the rails in – ‘Where do I mount the rails in relation to the 5U of space in the rack?’ to answer that question the bottom of the rails go at the bottom of the 5Us of space. Hopefully the image to the right illustrates this better!
