Disk enclosures and temperatures

leave a comment »

As noted in some recent posts, I’ve recently swapped the disks in a couple of servers for SSDs.

After a few weeks of 24×7 operation it was apparent that the SSD in one server was consistently running around 4-5 degrees C hotter than the other despite the fact that these are identical servers with a similar workload. The only difference between the two was that when I installed the first SSD I bought a bare drive and fitted it into a 2.5″-3.5″ adapter enclosure but when I bought the second SSD I bought it as an upgrade kit that included a pair of rails to allow it to be fitted in a 3.5″ drive bay.

The adapter enclosure is manufactured by Kingston and has several vents to allow air to pass through it. It seemed unlikely that heat could build up inside it but, nevertheless, it seemed to be the most likely explanation as to why one SSD was running hotter than the other. I bought another pair of adapter rails and replaced the enclosure.

And, yes, the server with the disk that was running slightly hot is now running at exactly the same temperature as the other.

Where have the 17″ 1920×1200 laptops gone ?

leave a comment »

The last four laptops that I’ve owned have all been Dells: a couple of Inspirons, a Vostro, and a Precision. Each has a 17″ screen with a native resolution of 1920×1200 pixels. Although this makes text appear fairly small, it’s a great for running Visual Studio when you want several tool windows open as well as the main text editor window.

With Windows 7 and Visual Studio 2010 now available I’m tempted to buy a new laptop just for VS2010 running on W7. The last laptop I bought was an Inspiron 1710 which despite being aimed at the home and small business markets and costing a relatively modest £700 has proved to be a capable and powerful machine for development. So, I thought I’d order another one with, if it was an option, an i5 or i7 processor but something weird has happened to Dell’s laptop range – 1920×1200 screens are no longer available. There seem to be fewer 17″ screen models and the few that there are all have a 1600×900 resolution. The only laptops with a 1920×1200 resolution that I could find on Dell’s UK web site were Precision models with a 15″ screen costing around £2000.

What’s going on ? Where have all the 17″ 1920×1200 screens gone ?
