Over the years I have worked in hundreds of data centers. The number is probably closer to 1,000 than 100. Each data center has its own nuances and policies. This varies by company but can vary by data center within the same company. It can be quite the tangled mess to keep track of. As I was sitting here not able to sleep I wanted to come up with a list of some things Data Centers should do to make tenant life easier. Some of these you can do yourself, and I do for many sites. Some of these overlap, but are important to mention a few times So let’s get into it
Don’t assume your customers know what is going on
Some of us don’t visit these sites very often. Many times it’s late at night when no one is around except security. Much of this list revolves around the things we don’t know which may be common knowledge for those at the data center everyday.
Do I need to open a ticket to access my equipment? Some facilities I have to. Others I don’t.
Have a published facilites and helpline
I ran into a situation today. I was visiting a site today and had to go through a turnstyle. Come to find out I was on the wrong floor, but I did not realize that until someone came to help. My cell phone was at 5% and I had to end up calling the business development guy to get ahold of someone. Those Sales guys know everyone!
Where to Park
This may be obvious if you work at the building every day, but to the occasional visitor, this can be confusing, and potentially costly. Data centers in downtown areas really need some sort of updated information on a website outlining this. Facilities near sporting arenas are the worst. It seems you need a decoder wheel on when and where you can park before and after games. Some cities are better at marking this than others. I once had to walk 10 blocks lugging a switch because I could not park near the data center due to a football game.
What doors are open at what times
If your building has multiple entrances keep an updated list of the hours of each door. Nothing like unloading 10 switches onto a cart and finding out you are on the wrong side of the building. Can I bring carts and equipment only in a certain door or loading dock?
What to do when you enter the building
This is another obvious thing to those who use the building on a regular basis. Do you check in with the security desk first? Do you need to sign in if you have a badge? In order to help understand some of the issues, I will take you through getting to equipment at two data centers in different cities owned by different companies.
Dats Center 1
Upon entering I pass security but do not have to check in with them. I use my badge on the gates, but not the top sensor, the one on the angle facing me. Both accept badges, but my badge only works on one. After my elevator ride to the floor my equipment is on I badge in through a door. Next up is the man-trap (sorry people trap sounds dumb). I am presented with a reader with a pin pad, This pin pad is the same as many other of the data centers I visit. However, at this particular one I just swipe my card and do not enter a pin. The light on the reader flashes between red and green rapidly. I have to remember this is not an error message, but normal for this data center. I nervously open the door hoping I don’t set off any alarms. Once inside the man-trap I have another similar keypad to let me into the data center room. Swiping my badge results in the same rapidly flashing red and green and I am in the data center and can proceed to my rack.
Data Center 2
In order to gain access to the building I swipe my card at the exact same pin pad, I mentioned in the above Data Center. I have to remember at this data center I need a pin. I enter my pin and the reader beeps the light turns green. it’s important to note it does not flash like the previous pinpad at the other data center, even though it’s the same model. I can hear the door mechanism unlock. Once inside it is a similar procedure in order to get through each door until I get to my equipment. On the way out, I just swipe my badge and do not have to enter the pin. The pin is only for going through the door on the way in. The system knows you have been through that door and just is looking for your card swipe to let you out. At this data center, you do have to remember to swipe your card before you leave a door. The door will open without a card swipe but will set off alarms. This can be easy to do if you are distracted.
Other data centers make you check in with security and sign in before using your badge to go onward into the depths of the facility. Others, the building security personnel have little to do with the data center.
Also, train the building security folks to realize there are many of us who don’t visit the facility on a regular basis. I have had many a security guard ticked off about my questions on procedures.
Maps to my equipment
If each data center provided me a map of the floor where my equipment is I would probably love them forever, at least send them a Christmas card. If I could take that map and draw an “x marks the spot” type of map that would help me remember where my stuff is. If the data center provided this as part of a welcome package they might get upgraded to cookies for Christmas.
The things you don’t need to know until you need to know
Do your badges expire after so many days/weeks/months of inactivity? I have some facilities where my badge expires after 30 days of inactivity. Just about every visit to the facility involves getting my badge reactivated. It seems this procedure changes each time.
If I have equipment shipped is it only available to get out of storage at certain times?
Are there crash carts on site for keyboard, mouse, monitor? What is the procedure for getting access to those?
Go through what a customer would have to at 3am on a Tuesday night
If you are a data center, especially one that says customers have access to their equipment 24/7/365, go through some mental exercises as if you were a customer. It’s okay if you can’t do certain things during business hours only, knowing ahead of time can solve a ton of issues. Just some things a customer may go through
-It’s 3am and my server crashed. Is there a crash cart? How do I get access to that cart?
-Where do I put my cardboard and such when I am done? Do I have to carry it out with me or is there a specific place I can put it to be recycled/trashed?
-Is there wifi? If you want me to fill out a ticket to get stuff done and I have no internet due to being inside a structure that doesn’t help. Going out in the hall or even outside is not productive.
Knowing what the capabilities of the facility during different hours can really help. If a noc technician needs to escort me to the meet-me room and I can only do that during normal business hours that is something very handy to know. I am fine with that if I know ahead of time and can plan. Don’t say you are 24/7/365 and I can’t add a new device to my meet-me-room rack at 7am on a Sunday because no one is available.
e-mail lists are your friend
I have a few data centers which keep a pretty active list of what is going on at the facility. things like break room closures, parking restrictions due to construction, etc.
In other words, make it easy for your customer to follow your rules and procedures.

I am excited to reveal that my quarterly interconnection update has
transformed into the Interconnection Quarterly, a hand-tailored,
independent briefing on the interconnection industry. Right now, my plans
are to publish the Interconnection Quarterly shortly after the last public
companies report earnings, as I’ve done with the previous updates. This
may change in the future, but for now, this is the plan.
In this inaugural issue, you’ll find the latest financial and business metrics
for select data center operators and interconnection platforms, as well as
insights into key developments and newsworthy events that occurred
within the fourth quarter of 2020.
We’re at an important juncture for interconnection, and while it still may
be seen by some as just a basic service that a data center or colocation
provider must offer, the truth is, that interconnection is much more
From cross-connects to cloud networks, the constant here is in the
connection. How that connection is established and what you can do
with it is what’s changing as we adapt to a world powered by software in
My friends over at FMC products have a good article on airflow in racks
Fiber Store now has bulk ethernet cable in several varieties. Both Cat5, Cat6, and even Cat7.
Mikrotik CCR1072 for an ISP network running BGP.
Preseem now supports IPv6 for all use cases. This includes the ability to assign subscribers a prefix of arbitrary length.
IPv4 with Prefixes of Arbitrary Length
Previously Preseem modelled subnet assignments to customers as a number of /32 assignments. For example a subscriber who was assigned a /30 would result in four internal /32 mappings. Preseem now supports assigning any prefix length to a subscriber without expanding these into /32 entries internally.
Some quick notes and screenshots from the OpenGear Resilience Gateway https://opengear.com/products/acm7000-resilience-gateway . The model I am working with is the ACM7004-2-L. It has 4 serial Cisco Straight pinout, Dual 1 GbE Ethernet, Global 4G LTE-A Pro cellular, 2 DIO, and 2 output ports.
So what does this thing do and what can it do for you as an ISP? At the basic level, this is a console server with multi wan capability. What this means is when the crap hits the fan you should be able to login to this device across the internet and see what your switches and routers are doing across a console connection. In most ISP scenarios they are bringing in their internet connections from another provider and landing it on a switch or a router. As most followers of this blog know I am a fan of switch-centric based setups. this means your transport and internet connections are landed on a switch or switches and then a router on a stick attaches to these switches.
So why would you need this setup? Not every POP site justifies, or has available multiple transport or internet connections. Imagine you have a switch plugged in and that switch doesn’t come back from a reboot or power event? Without a console server such as this you are driving to the site and plugging in a console cable to see what is going on. With this you can access the device over on of the multiple wan connections, including a cellular connection to gain console access.
Even in redundant setups, a console server can give you insight into what is going on with a router or switch. You can access the console port without ever having to drive. Is the switch booting? Is it getting stuck on a bootloader somewhere? This is all information you can gain from the console port.
Some Screenshots of the Gui. One of the things I like is the dashboard. I am a sucker for dashboards. One reason I am is on any new piece of gear I am reviewing or learning a well thought out dashboard will give me much of the information I need to know. Are my interfaces up? Have VPN connections established? These can help me learn as well as save time troubleshooting
Some interesting notes about the features of this device. It does have environmental status indicators. If you have a device that you can plug into one of the console ports either via USB or rj45 console you can use the gateway to monitor this. Couple this with the Nagios and/or SNMP integration you now have a temperature, door alarm, or other sensors for your remote sites.
Other notable features include Digital Input and output, remote syslog monitoring, IPSec and OpenVPN, and many other features. If you are deploying lots of these Opengear has a Lighthouse Server for centralized management.
One of the best things I like about this is you are able to access the console server via the web interface. And the best thing? No Java required. This saves from remembering complicated port numbers, for when you ssh and want to access a specific device.
So how am I using this in a network? this device is going at a data center. The client has two cisco switches and two mikrotik routers which will plug into this. It will have an in-band wan connection on a management vlan directly into both routers. If both of these routers are down the gateway has a cellular backup with a IPSEC VPN to a router in a remote data center. You could always switch this up by connecting your second ethernet port into a secondary ISP in the data center. Some networks have a management router where management devices such as this plug into. I have done this with Mikrotik 4011s and it works just fine. I can plug an in-band connection into the mikrotik and a secondary ISP such as a cable or other ISP in the data center.
The cost may discourage some folks. On Amazon, these are just under a thousand dollars. If you need more console ports the price goes up from there. To them, I say what are the costs of downtime and your time. For this client, the closest tech is an hour away. I am two hours away. If a simple firmware or bootloader command fixes a switch not booting and turns 2 hours of minimum downtime into 5 minutes that is a huge win.
Look for a video overview soon.
