The Planet Blog

This is my first blog post, so I thought I’d share a funny story about my first few days at The Planet. Coming from a predominantly networking background in the Internet service provider (ISP) world, I was thrown for a loop the first time I looked at our server descriptions.

As I browsed through, I noticed the labels for “bandwidth” and “uplink port speed” as two separate items. As I said, coming from the ISP side of the technology industry we defined “bandwidth” in a completely different fashion than the hosting industry. To me, bandwidth has always been defined as how big the pipe is that will transmit or carry data. So when I saw the “Bandwidth” and “Uplink Port Speed” labels, it really threw me for a loop (nothing like a routing loop to really screw up your day – HA!).

In the ISP world and more to the actual definition, bandwidth has meant the width or depth of allocated bands of frequencies in a transmission channel. It’s the width of the spectrum a signal occupies. Think of it in terms of tubes or pipes – a two-inch pipe or tube has less width or depth to carry or transmit things than say an 18-inch pipe or tube. In this example, the two-inch pipe would be an ADSL line vs. a DS-3 line.

“Bandwidth” always seems to be confused with data rate or capacity – otherwise known as how much “stuff” can I send at a given speed (usually measured in a per second time unit). This would be closely related to what we label as “uplink port speed” and “bandwidth,” respectively and as we define it, more than the definition of “bandwidth” as I have technically defined it.

So that brings me to the next thing that may come across your mind – what do “bandwidth” and “uplink port speed” mean with The Planet and the hosting industry?

Let’s hit “bandwidth” first. Most, if not all, of our listings show them in some thousands of GB (GigaBytes). Our Conroe’s come with a default of 2500 GB of “bandwidth” per month. From our definition, that means you can transfer 2500 GigaBytes of data in one month – it’s an aggregate of both inbound and outbound data to and from the Conroe server. But still, what does that mean?

We’ll, let’s say that you had a database that was 2500GB in size (massive database!). If you started transferring it from this server to say another server, outside of The Planet, and you wanted to do it over 30 days (approximately, one month), then using a nice little conversion formula (2500GB/month * 1 month/30days * 1 day/24 hours * 1 hour/60 minutes * 1 minute/60 seconds * 8 bits/1 Byte) we see that the minimum “uplink port speed” should be a 7.72 Mbps connection – a slower than 10Mbps link connection, which was the old de-facto standard that we used to use for connecting PCs and servers to LANs. But this gives you an idea of how your decision in “uplink port speed” can be directly proportional to how quickly you need to do business.

Now we all know that we have a faster connection than 7.72Mbps, especially when the Conroe is defaulted with a 100Mbps “uplink port speed.” So what does this mean when we run the formula this way? Let’s say that we use all of the “pipe” allocated to the 100Mbps “uplink port speed” for the entire month (to remain consistent with the above example). Plugging our numbers into the formula, but in reverse (100Mb/second * 1 Byte/8 bits * 60 seconds/1 minute * 60 minutes/1 hour * 24 hours/1 day * 30 days/1 month) we see that we can transmit inbound and outbound about 32,400GB or 32.4TB per month of data! WAY beyond the specified 2500GB or 2.5TB per month that we default to the Conroe server.

They are related, but do not necessarily equal one another in relation to their monthly ability. What’s important to see is that you know what both are capable of. One tells you how fast you can transmit data given the bandwidth (this is the “uplink port speed”) while the other caps or limits the amount of data that can be transmitted in a given month to and from that server (“bandwidth”).

This month, The Planet has launched its Cogent “unmetered bandwidth” offering and this is where customers can quickly learn how valuable even 10Mbps of “unmetered bandwidth” can be! A 10Mbps, unmetered “uplink port speed” would yield 3,240GB or 3.24TB of “bandwidth” per month! A very nice savings at $200/month!
