Tied Down Cabinet in Public Colocation Data Center Facility

Had to do some late night work at the Houston Data Center. While I had the chance I took some ok shots of a beautifully tied down cabinet. It is very hard to get the wiring right in a public colocation facility. This is at Internap where they use a slightly larger cabinet and you can do some wire management. The cabinets are Mid Atlantic and you can put in larger servers and SANS. I hate how at a lot of public colocation facilities the door almost slams the back or front of my servers. Notice the use of Panduit stress relief bars. The wire management that comes will Dell equipment usually does not work well in a public colocation facility. I never use it on 1u servers as this creates a microwave in your cabinet. I also recommend using 208 power where possible less circuits to manage.

Clear Wimax in Houston so far so good Fast Speeds

Clear let me have a few USB cards and the Motorola home modem to play with. I really like what I see so far. The USB has been quicker than I expected and the home modem is good I just wish it could be bridged so I can pass the public IP address to my firewall. I think the modem is a very economical redundant connection most firewall support multiple isp's and this is easy to add.
As for speeds I'm seeing max 12megs down and 2 megs up in some areas. The modems tend to work best the higher you go in your building or house. You will also notice that the signal strength will vary greatly. The nice thing about the Motorola home modem is that you can move it to get a better signal on the laptop this is not so convenient. In the Woodlands I got 8 megs 1 meg up. In Cypress I'm seing 12 down and 2 up on both usb and the modem. In the energy corridor I was having trouble getting a good signal 3 megs down and half a meg up. Downtown in an office building was tricky, but I was able to pull 5 megs down and 1 meg up. If you go deeper into a building you will slow down on your upload, downloads slow but not nearly as much as the upload.
