Ghetto IT: ESXi 5.0 Virtualization server on a budget AMD laptop


Here is my weekend ghetto ESXi VM server. A $200 budget AMD laptop.


I have to convert a rather large physical server at home so I jury rig an unused laptop.

This laptop has no love whatsoever. It was a $200 special from Staples or Office depot that you find on Black Friday door buster sale. The household is pretty much a tablet household and we don't have much use for it and it has been sitting in the closet for well over a year.

The laptop is a HP DV6 Pavilion with an Athlon Turion P540 processor. I reckon it is a celeron speed based CPU. The thing it has going for it is 8GB RAM (ram is cheap) and an eSata port. Otherwise, it is a rather horrible (1366x768 resolution on a 15.4" screen, awful keyboard, and lousy trackpad).

I figure I can create a makeshift ESXI server to create a makeshift datastore that will eventually be migrated to a "real" server.

To my surprise, the laptop was perfect. I made a bootable ESXI usb stick that previously worked on another workstation and connected a SATA dock. To my surprise, everything works. With an ethernet crossover, I was able to make some backups and testing.



A cheap $5 USB USB stick was my boot OS. ESXi happily boots from flash storage.



(ESATA cables and a cross over ethernet makes this portable.)

I was able to dock an undock drives easily. The drives then showed up on my production server automatically. I managed the whole session with my macbook and a cross-over cable.

In Conclusion, those cheap Walmart/Staple/Best Buy budget AMD laptops can come in handy when you need to improvise. I like the fact AMD doesn't gimp their virtualization features in their CPU. Unlike the cheap Intel Celerons/Atoms/I3s, some of the AMD offerings are quite nice.

Thinkpad T420 Impressions


Right about now, manufactures are releasing a bunch of new Ivy Bridge laptop models. With that said, it is a great time to get major discounts on last generation Sandy Bridge models. Ivy Bridge promises to be 10-20% faster but is it worth the 40% premium when there are significant savings on the last gen core Sandy Bridge?

I recently took advantage of those major discounts during the Memorial Day close-outs and picked out a Thinkpad T420 with a corporate discount. I'm glad I got the T420 over waiting for the newer T430.
Most notable change in the newer models that will infuriate traditional Thinkpad loyalists, Lenovo is abandoning the traditional keyboard for the island chicklet style. With that change and the major discounts ($800 or so w/ tax and shipping), I could not resist.


I intend to run a Linux workstation with multiple virtual machines so I had the following requirements:

  • Higher than 1366x768 resolution screen. Check! The T420 comes with a 1600x900 display.
  • More than 8GB of RAM. Check! My T420 runs 16GB.
  • Processor support for advance virtualization. Check! i5-2540M has VT-D/VT-X support for hypervisors.
  • The ability to run WQHD (2560x1440) monitors or higher. Or the ability to run two FHD(1980x1080). Check! T420 has displayport and I wanted to avoid HDMI and its limitations.
  • Expansion, docking, and modular drive expansion bays. Check! The Thinkpad can use a docking station that has multiple video outs. The Ultrabay allows me to swap out drive caddies.I intend to run three SSD drives on the machine. 256GB SSD in the main drive bay for the OS, 32GB mSATA in the PCIe slot for swap/VM,  750GB Seagate Momentus Hybrid in the ultraboy.The 34mm express port will allow me to attached a eGPU (external GPU card via express-to-PCIe) to power even bigger and more monitors.


When you look at all my requirements, the Lenovo Thinkpads hit all the right notes. Ultrabooks were out of the question.

The beefier workstation class laptops like the W520 are nice all and with their FHD screens but I explicity wanted the easiest Linux laptop to run multiple 27" and higher displays.
The W520 can run 32GB of RAM in a quad-core configuration but the discreete optimus switching graphics is problematic with Linux and multi-monitor setups involving displayport/dual dvi.
Furthermore, the weight,enormous girth,and bricky 170 watt power supply, and short battery life of the W520 turned me back to the T420. And on a surprising note and unexpected advantage, the T420 is easily hackintoshable if that matters.

So, the T420 or the T520 seems to be the most ideal laptop for my usage. If you are a power user with similar requirements, look no further than the Thinkpads.

What can I say? In a nutshell, it is a "real" Thinkpad. You either like the looks or you don't. If you think the machine looks dated or old school, then this is not the laptop for you.
To me, it has an intangible elegance to it. The spartan, all black, matte professional appearance screams enterprise ready.
This is a professional workhorse and it makes no excuses for it. The only visual cues that separates this from a 10 year old Thinkpad are the video display port, e-sata jack, and the various inside Intel stickers.
So far, Lenovo has done a good job of not messing  up IBM's iconic design.

I'm currently working on various deadlines so I haven't had time to set it up and play with it. In the coming days/weeks, I will follow up on my experiences with it running Linux.
I have the mini dock 3 (433710U ThinkPad Mini Dock Series 3), various ultrabay caddies, monitors, and various drives ready to go. I'm most interested in seeing hack together an eGPU (external graphics card) to it.

It will be interesting to see how well it compares with the upcoming, revised quad core Ivy Bridge Retina Macbook Pro 15" that I will be getting from work.
Between 4/5 high res monitors and 2 powerful laptops on my desk, it will be computing nirvana this year.

Post blog notes:

I got it running the 30" Cinema Display using display-port from the laptop and the dock with the basic install of Ubuntu 12.04. No hassles, No xorg config files. It was able to play a 720p MKV on the 2560x1600 display while running a Virtual Machine, compiling, and cloning DD the Windows partition. Impressive and hassle free Linux experience.

Whatever happened to true Docking Stations

Today, I won an ebay bid for a brand new Lenovo Thinkpad mini dock 3 and it brought back some memories. I am thinking about the convenience of docking at work and having my stuff all ready to go. No hassles of cables and clutter.

Unfortunately, modern day docking stations  are simply port-replicators for convenience. In the past, they are way much more.


Long before the turn of the millennium, you could buy a true desktop replacement docking station filled with full slots and expansion capabilities. I clearly remembered spending over $4,000 for an IBM Thinkpad 600e setup up with a Selectadock III. Dell and HP had a competing line of products for their workstation laptops. Apple had, well, they had the mini duo or duo dock.

The docking station of yore had full PCI slots and on-board SCSI. That was truly a beast and exemplified IBM's build quality. I remember adding all sorts of PCI cards like a dedicated MPEG2 decoder that can't even compete with modern smartphones. And remember the Adaptec 2940 Ultra-wide SCSI card? Yep, I had one of those running off a Thinkpad. I had "Scuuuuuzeeeee " server class drives.  I forgot, I also had a floppy bay Iomega Zip Drive. I could literally host a ISP back then.





I can't really complain about my new setup. A Lenovo port-replicator it is! I wonder how the Thinkpad brand would have flourished if IBM kept it.



However,today's laptops will do so much more. The T and W series Thinkpads have Expresscard slots and they can power dual/triple monitors up to 2560x1600 through displayport. Expansion is handle by USB and firewire.

The new Macbook Pros have Thunderbolt and you can get expensive Thunderbolt-to-PCIE bridge box enclosures. I've seen them set up with RED rocket video cards for working with 4K video.

Still, I can't fathom the possibilities if manufactures made full docking stations instead of port replicators. I also wonder what it would be like to have a modern day 600E/600X Thinkpad. Those things were built like tanks. 

I will post a review of the Lenovo "port replicator" and how it works with Linux in the coming weeks.

Goodbye Thinkpad X120e. A Long term review.




I just recently unloaded a trusty X120e on Craigslist. It served me well for over a year and it is now time for a newer Linux machine. A Thinkpad T420/T430 is now calling my name.

This post is going to be  a long-term review of the Thinkpad X120e.

Released in March 2011, the X120e, along with the HP DM1, were the first wave of AMD based Fusion ATOM killers. Unlike a typical netbook, these had better performing GPU (AMD calls them APU) and larger screen size.  Before the "ultrabook" craze, there were cheap netbooks and the Macbook Air. Since I already have a Macbook Pro, it made no sense for me to get another one. With a project that required Windows 7 and Kinect,  this machine landed on my lap. Since, I've been using this as a secondary/third computer.

I've been through various netbooks starting from the original Asus EEEPC 701, Acer Aspire One to a Dell Mini 9. The typical netbook resolution at 1024x600 was a god awful. So this was an improvement at 11.6" and 1366x768 resolution. Furthermore, it didn't feel as crippled and dog slow as the Atom based CPUs.

A bit bulkier than normal, it still was very light weight at 3.4 lbs.  Some notable feature include an SD slot, 3 USB ports,  and HDMI. Very much like any typical netbook except this was a Thinkpad. Some people wouldn't call it a real Thinkpad but to me, it was close enough The red nubby trackpoint and black plastic is what makes it a Thinkpad for me. I am a big fan of the Thinkpad no-nonsense spartan black business look.  Plus, there was the legendary Thinkpad reputation of their keyboards. The chicklet keyboard is one of the best I've used with decent amount of travel.

Battery life under Linux is about 5 hours. I hardly ever use Windows 7 but when I checked, the indicator always indicated 6.5 hours with aggressive power management.

As for upgrades, I added 8GB RAM and a 120GB solid state drive SSD. Despite the low-end CPU, the machine was rather snappy for my occasional use (database queries, shell scripting, and connecting to overseas VPN for downloading large files). I didn't play any games or watch any movies on it so I can't comment on multimedia capabilities. With the SSD, Ubuntu boots into login in about 15-20 seconds.

I had no problems with Ubuntu 10.10 and 12.04. Everything pretty much installed without a hitch. The microphone works, SD mounts, it goes to sleep, WIFI connects, HDMI works.  In other words, none of the typical Linux laptop nightmares. The only major complaint is the inability to power 1080p resolution in a dual display setup. It does not have enough processing power to run 1366x768 built in display and an external 1920x1080p at the same time. I could run 1024x768 along with a HD monitor. The other solution is just to run an external monitor and power down the built in LCD.

If you are looking for something medium budget, this or the newer 130e may be worth some consideration.
