Dell Inspiron 11 3162 Review

I bought this little 11" laptop off Dell's site after poking around and thinking it would be nice to have a little laptop again. I really missed my MacBook Air after I sold it - silly move that - so I thought why not consider this one? It's specs are underwhelming:

  • Celeron N3050 processor
  • 4GB of RAM
  • 32GB eMMC HDD
  • Bluetooth version 4
  • WiFi - 802.11ac+
For what it is, it performs quite well. It's crippled though. In fact - so crippled I couldn't get the thing to start a week ago. It would try to boot into Windows 10 and just hang and hang and hang - you get the drift. I let the power completely drain then tried again. Repair windows install was the next question.... grr. After completing this it booted. That's the only problem I've had with it.

I have had the chance to use it for a couple of presentations. The built in HDMI interface is amazingly handy and the Dell drivers work well for the system, allowing for quick and painless swaps between things. It also gets 8 hours out of the battery which is very impressive indeed. I've tested this twice, and after a full day of work it still had some go in it. 

The ergonomics aren't too bad - I find the keyboard a tad small. But to give you perspective, I'm typing this on a wireless Mac keyboard and I find that a tad small too. I'm most comfortable on an ergonomic keyboard, the Microsoft Sculpt is the current choice of weapons for that. The mousepad is responsive and I find it to work quite well.

All up, this little laptop was about $275 - this model was $300+ at JB HiFi. It's worth checking the manufacturer's site for these better deals. For the equivalent money at JB I'd have only gotten 2GB of RAM. That extra RAM can make an enormous difference! Can't remember if the disk was bigger was or not, but there is an SD card slot so I've already slammed a 64GB disk into that. Combined with network storage and the high speed wifi, I'm set to go.

I think this machine is pretty good. I've got a real dislike for Windows 10 and the way privacy and updates are being handled, but I'll leave that for another post. I'm going to investigate putting Linux on this machine. I think it'll go really well with it.

For a cheap laptop, it's got some solid specs and it's reasonably good to use.

Dell T110 Server - older tech still doing the yards

The last time I was out in Coober Pedy, I saw a lot of Toyotas running around. Landcruisers mostly - a great vehicle and out in the Red Centre with some pretty harsh conditions, they were the vehicle of choice. Solid, reliable, amazingly well built. It's a bit like the older Dell servers still kicking around.

To my case in point - the Dell T110 Server. These servers, brand new, with a Xeon Processor, 4GB of RAM and a 250GB HDD were around $1400. We got several cheap, added RAM, disk and an OS and sold them to customers. The basic spec was pretty sound:
  • Intel(R) Xeon(R) CPU X3430 @ 2.40GHz 
  • 4GB of RAM (maximum 16)
  • Dell PERC S100 onboard RAID (fake RAID but still OK)
  • space for 4 disks
  • tower configuration
 About 18 months ago I was given one of these servers by a grateful client after a particularly painful weekend migrating one server to another. After thinking about it for a bit, and knowing the S100 RAID card is Windows only (Linux won't see the arrays, just the disks - use AHCP if you're using Linux), I decided to pop Windows 2012 Server on and run a bit of the Hyper-V action for shits and giggles. In order to do this and to solve a tricky customer problem, I upgraded the server a little bit.

I added two 250GB SSD disks and made them the primary array, with the two 250GB HDDs as a data array. I installed Windows 2012, set up Hyper-V and then built a 2008R2 server as a VM. I also added more RAM to max it out at 16GB. Now, the 2008R2 server boots up in under 20 seconds! It is so quick and as I was using it to try to repair a broken SharePoint (see my previous post on this) I was very happy to have a machine that would restart in the blink (almost) of an eye.

Fast forward to about 3 months ago, I ditch the 250GB HDDs out of it and upgrade them to 2TB drives giving me a data array of 1.8TB for stuff. I've used the machine to create (and destroy) about 20 different VMs for testing and it has been reliable and solid for all the time. Suffice to say I'm very happy with it.

I was puttering around on eBay about 3 weeks ago and saw one of these for sale for $150! I grabbed it, as quick as possible. It turned up with the base spec. Using some old stuff lying around I've upgraded it to be a 2012 server, with 16GB of RAM, a 1TB HDD based primary array and a 1.8TB HDD based secondary array. This one is as solid as the other! I've since moved the bulk of the family data to it, configured some nice backups and off it goes. I've even put Hyper-V on it and run up a 2016 test server - it goes quite well.

All in all, I've spent under $1000 for these two servers and they comfortably handle everything I'm throwing at them. The original server, at one point, was running 2008R2 with SharePoint live for a client with 20 people using it, several Linux servers and a Windows 2012 based file server - all on hardware that is 5 years old. The SSDs really make the machine fly - a worthwhile upgrade indeed. In fact, as they get cheaper I can see myself upgrading the data array to SSD... it'll be pretty good!

The next gen in the T110 - the T110 II has a better Xeon processor in it, with double the RAM capability and they also came out with hardware based arrays. I'm keeping an eye out for one even as I write this.

If you're looking for a server to play with, or to manage a small workforce, then it's hard to go past something like this. Need redundancy? Buy two instead of one and set up live migrations (next on my to-do list).

I love this older tech - I can still get brand new replacement parts (like PSU's) and the original gear is running happily. It's cheap and it works - get around it!
