Dual Power supplies and Dual Power in the Data Center

If you are colocating in a data center you can only use 80% of your power circuits capacity. For example you can only use 16 amps out of a 20 amp circuit. So if you are running servers with dual power supplies most server brands will split the load across both power supplies. In this scenario you can only load down both circuits to 40% so if you do have a failover the live circuit will only be at 80% capacity and you will not have to worry about popping the circuit breaker.

The going price at most data centers for a 110v 20amp is $300 with ups and generator backup. For 208v 20amp the price would be $600. For a redundant B circuit 110v 20amp is going to be half $150 and $300 for 208. I highly recommend switchable PDU's. This will allow you to power cycle you equipment remotely and most of the better models will meter the power so you can know what your usage is. You can find a good quality remote manageable PDU for $350 to $800.

There is not a single Tier 4 data center in North America that offers public colocation

Watch out for data operator claims of Tier 4. Has the facility actually gone through the certification process? If they are a facility worthy of certification then they would not mind spending the extra $30,000 for the blessing of their design. Tier 4 certification for a data center or having a Tier 4 design is not easy to achieve. The link above is a list of Tier certified facilites globally.
Data centers are incorporating this certification into their marketing even though even though the Uptime Institute has not certified them. All the facilities that are Tier 4 certified are corporate data centers not open to public colocation. There is only one facility that is tiered certified (Tier 3) that offers public colocation in North America.
Another point to consider is that Tier certification only pertains to the four walls of the data center outside factors are not taken into consideration, like weather , earthquakes ect....
How does the power, coper and fiber come into the facility? Aerials? Encased in concrete?
How many Generators? Diesel or Natural Gas?
Flood Plains?

The future of Search - Local Search?

I was quite surprised to see that Google had a SuperBowl ad. It was interesting that they used local search three times in the commercial. I noticed that just about any regional or local search will trigger local results. The problem I see is that Google show's local results based on location and if you are located in the center of the city you have a big advantage. Even if you are in the top three organic results you are still pushed down the page by the map and the local results. Your seo efforts are very easy if you have a downtown city center relevant business.
