Dell PowerEdge 13th Gen Fan Noise

I recently came across the opportunity to assist a client with installing their new Dell PowerEdge R730XD. Quite the beefy server config, 2x10core CPUs, 128GB of RAM, 12x4TB NL-SAS, you know, all the goodies. This machine is slated to replace an aging T610 that has seen better days performance-wise.

I went ahead and put an Intel 10GbE card in the server since all other hosts in the server room including both backup boxes are 10GbE enabled and are connected to our new Netgear 10GbE switch. Keep in mind this was an industry standard PCIe 10GbE card, a particularly good one, the Intel TX540-2. After installing VMware ESXi, and later, Windows Server 2012 R2, users were complaining about the loud “jet sounding” noise coming from the server room. After logging into the Dell iDRAC Enterprise card I immediately noticed that the fans were running around 92% which was roughly 15K RPM or thereabouts. This was regardless of operating system mind you, so I couldn’t even blame Windows OR VMware this time.

After looking around online at various forums I realized that the system was running the fans near max speed/volume due to the presence of a non-certified PCIe card installed into the system. For all intents and purposes, non-certified means you didn’t pay through the nose to acquire the identical hardware from Dell. Essentially, since the Intel card doesn’t carry the Dell specific code/firmware to report back that “all is well over here in PCIe/temperature land”, the system defaults to running the fans in jet engine mode. For posterity’s sake and to clarify, this will happen on pretty much any non-Dell card that is inserted. In researching the issue I found numerous folks that put actively cooled GPUs, old school 4x1Gbps network cards, you name it, high speed fan noise.

Well no big deal, all you have to do is go into the Dell BIOS and modify a setting or two so that the system doesn’t run the fans at full steam when a card inserted right? Wrong! That would be the logical assumption and design choice to make so you know they didn’t make it that easy. Read on below to understand how I finally got this system to quiet down. The info below is compiled from many sources and some of my own figuring out, just though it would be helpful to have it all in one place.

Step 1: Enable IPMI
For this step enter your Dell servers setup/config screen and get to the remote access configuration/iDRAC setup. In the iDRAC setup you need to do all of the standard stuff like assigning an IP and setting user credentials etc, but you MUST also turn set “Enable IPMI over LAN” to yes. This setting is crucial to completing the steps below successfully.

Step 2: Get IPMI tools
Linux users can use their preferred package/distribution method to obtain ipmitool while Windows users will need to grab the Dell OpenManage BMC Utility and get it installed.

Next, open up and command prompt and navigate to the directory the BMC utility installed to, on my system this was: C:\Program Files (x86)\Dell\SysMgt\bmc\

From there go you will see several files, the program that we are using here is ipmitool.exe. Go ahead and run ipmitools.exe without any switches/arguments just to make sure its installed and working.

Step 3:
The third and final step is essentially ‘the fix’. This is where you can check the status, and then disable or enable the systems cooling response to third party cards that are installed on the PCIe bus. This part was a little frustrating at first because I was working in the right direction and was just about there but the commands weren’t being sent or interpreted the way the should have been.

You must use the lanplus option instead of lan but it is important to note that lanplus does NOT work unless you’ve enabled the “Enable IPMI over LAN” setting that I mentioned back in step 1. The non-intuitive part about that was that although I was running the right command aside from lan vs lanplus, I really didn’t get any clear feedback as to why the command wouldn’t “take”.

Anyhow, here is the base command which you need to acquaint yourself with:

ipmitool -I lanplus -H ipaddress -U root -P password raw

Obviously you will need to substitute your own iDRAC ip, user, and password. After that, just tack on one of the three commands below.

Disable Third-Party PCIe Card Default Cooling Response:
ipmitool -I lanplus -H ipaddress -U root -P password raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00

Enable Third-Party PCIe Card Default Cooling Response:
ipmitool -I lanplus -H ipaddress -U root -P password raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x00 0x00 0x00

To check the current third party PCIe card default cooling setting:
ipmitool -I lanplus -H ipaddress -U root -P password raw 0x30 0xce 0x01 0x16 0x05 0x00 0x00 0x00

This response means disabed:
16 05 00 00 00 05 00 01 00 00

This response means enabled:
16 05 00 00 00 05 00 00 00 00

After disabling the third party cooling response my system went from the previously mentioned 15K RPM mark down to a user verified sane noise level/speed of around 6K RPM.

A key takeaway and disappointment for me is that in this day and age of widespread standards and simplicity, things are becoming increasingly proprietary and complex.

Product Review: EnGenius Access Point

Last week I ordered an EnGenius EAP300 access point from NewEgg (a vendor who deserves a review of it’s own) and it was waiting for me when I got home today. I have been having trouble with a NetGear WG103 and contact with support has been unsatisfactory.

The product design is very functional. It pretty much resembles a large smoke detector. I was looking for a small ceiling mountable device that supported PoE and this fits the bill. This device is advertised as a business-class, high power access point. Several standard security options are supported.

Configuration was fairly easy for anyone familiar with provisioning wireless devices. However, I do not like devices that come configured with a static IP. It is a minor hassle to reconfigure a laptop or other device to configure the access point. Once I got past that it was a simple matter of connecting to the device’s web GUI.

Initial tests included watching shows on NetFlix and Hulu Plus from an Apple TV. The streaming was flawless. The next test was streaming a .mkv movie to a PC. Again this worked flawlessly.

Next step will be to mount this device in its final spot and test out the PoE adapter. Stayed tuned for further info.

Desktop, Laptop, Tablet, Smartphone

In my household there are three MS Windows 7 desktop PCs, one MS Windows XP laptop, one Debian Squeeze laptop, one MS Windows 8 pen tablet, one MS Windows 8 slate, one Android smartphone, two iPhones and two iPads. Work provides another MS Windows XP (soon to be MS Windows 7) laptop. Strictly for media access, I have an AppleTV and a TiVo Premiere. Finally cancelled the DirecTv service this week. I am also in the process of rebuilding a FreeNAS box for media storage. Nowhere near the ridiculousness of some households, but enough to be annoying at times. One of the iPhones and most likely the pen table are on the way out.

All of this begs the question – what is this crap used for?

The real answer is that there are a lot of unused cycles on this equipment. Two of the desktop PCs, the AppleTV and the TiVo are strictly for media playback (Netflix, Hulu, Pandora, iTunes) and this averages less than four hours per day. I have been looking in to open source media players but have yet to use one.

I like using my Debian laptop but the battery doesn’t last very long. The iPad has the battery life but not the functionality of the laptop or the slate. I read and send the majority of my personal email on the Android phone. I maintain four non-work email addresses and do not use a mail client other than mobile. The slate device is very functional, but if you go the MS route, there is licensing to consider. I mostly use open source products to meet my personal needs.

What is your primary device? Discuss.

HP ProLiant MicroServer Flexibility

I’ve been meaning to put some of my thoughts on the HP MicroServer N40L for quite some time and just haven’t made the time to do it, so here goes.

Long ago I was searching for a reason to purchase and play with HP’s MicroServers and got my chance when a client asked for an affordable backup device. I jumped at the chance and ordered one of the N40L’s. These units are listed as part of the ProLiant family of servers which sounded promising, but being the skeptic that I am, I didn’t expect much for the seemingly measly $350 price tag.

The unit comes with an AMD dual core CPU, 2GB of RAM, 250GB HDD, and a 1Gbps NIC. The system has a mini-PCIe slot for a remote access/iLO/DRAC type card, and a second standard PCIe slot. Although the system ships with only a single drive, all four bays have “hot swap” trays/carriers, making adding additional disks no problem. I say “hot swap” because I am pretty sure that the backplane/controller do not allow actual hot swapping in its true sense, YMMV. Another note on the hardware; the motherboard can be easily removed from the system by disconnecting a few cables and backing out two thumb screws. The board is on a simple and quite brilliant tray assembly which makes removal, upgrade, and insertion simple. Do yourself a favor when you purchase the system by maxing out the RAM at 8GB(DDR3/ECC) and adding the optional iLO/remote access card. For basic NAS and low end Linux server duties the 2GB will work fine and you will have no regrets, but going to 8GB really opens the doors, more on that next.

Before I jump into exactly what it can do, it is worth mentioning what YOU should not do with it. For instance, don’t try and be a hero to your clients by touting this as an ultra affordable server solution. I have read of several people putting SBS on this box and then using it as the primary file and mail server for 20+ users. Don’t be a dummy, if you’re trying to service your clients properly get them a truly redundant system with hardware RAID, dual PSU’s and things of that nature. You are providing a disservice to your clients if you use this in a place it should not be used. Responsibility rant over…

With the remote access card, 8GB of RAM, and a couple of SATA drives, you are ready to play. This is the little server that could and it shows. The thing runs VMware ESXi5, Linux, Windows, FreeBSD(FreeNAS) and many other things. An important thing to remember is that the included disk controller uses fake RAID/driver assisted RAID so don’t expect RAID support outside of Windows. With that limitation in mind, this makes the ideal small business backup device, home virtualization lab, or any other number of roles you can through at it.

Fast forward to today and the device has served me and many others quite nicely. Although not a comprehensive list of installs, I can confirm successful installation on the following operating systems:

  • Debian Lenny (i386/AMD64)
  • Debian Squeeze (i386/AMD64) Currently Debian stable release
  • Debian Wheezy (i386/AMD64) Currently Debian testing release
  • Ubuntu 10.04 (i386/AMD64)
  • FreeNAS 0.7 (i386)
  • FreeNAS 8 (i386/AMD64)
  • VMware ESXi 4.1
  • VMware ESXi 5.0
  • Windows Server 2008 R2
  • Windows Small Business Server 2011
  • Whew! What a list and that just touches the surface of what you can run. Those just happen to be the configurations that I have tested with success. My current configuration consists of the base system running 8GB of RAM, iLO card, 1x64GB SSD and 4x1TB RAID edition drives. I’ve got Debian stable AMD64 running on / and have 4x1TB RE drives using Linux md RAID in level 5 mounted on /home. This acts as my internal NFS server and virtualization lab. The system runs vm guests well through KVM although you will have to watch the CPU. Being a dual core 1.5GHz, the system will usually run out of CPU before you hit any other bottlenecks.

    In conclusion, if you need a flexible and affordable storage device for most small business or home needs, a cheap virtualization lab in a box, or similar configuration, you will not be disappointed by this device.

    Product Review: Cowon O2PMP

    Note: to achieve the appropriate reverent tone, read this post in the same manner as a Catholic priest holding Mass in Latin

    There are many, many PMP (personal media player) devices on the market today and many are pretty decent and get the job done. Good or bad, the iPod seems to be the gold standard against which all others are compared. And to be honest, the interface is pretty easy to use one-handed while driving.

    That notwithstanding, there is another device that deserves serious consideration; the Cowon O2PMP.

    Cowon Systems (South Korea) was started in 1995 with a primary focus on software development. The company released their first audio player in 2000, the CW100. A key component of the Cowon PMP is the JetAudio software application. The Cowon O2PMP was first produced in. Device specifications include a 4.3″ screen, flash-based storage (8GB, 16GB, 32GB), USB 2.0, TV output, SD card slot (up to 16GB), voice recorder and several other features. The device comes preloaded with a very diverse support of audio and video codecs; FLAC, MKV, MP3 among the most common in use. Advertising claims battery life of 8 hours for video playback and 18 for audio playback.

    Unfortunately Cowon O2PMP production has been discontinued. This is a tragedy… However, there are still decides to be found on the used market for under $150. When you get a device, go to the Cowon website and make sure you load the latest firmware.
    I have owned two of the 32GB models. Still not sure what happened to the first unit, after flawless performance for over a year I had completely drained the battery on a long red-eye flight. I ran through all the troubleshooting steps and it has not worked since. Unit #2 has been working as I expected for about six months. I travel a bit for work and this makes the flights bearable. I watch movies, TV shows and listen to music and audiobooks. For anyone used to watching video on an iPod, the Cowon screen seems huge by comparison. Much closer to an iPhone display. Battery performance is as advertised and it easily charges completely overnight while you are sleeping. Media management is as easy as you please. Unlike Apple devices which require iTunes, the Cowon devices work with any OS (I have tested various Linux and Windows). Plug the included USB cable in to any available port and the OS recognizes the device as a removable storage device. You will quickly find folders for Music and Video, and a few others. Simply copy your media to the appropriate folder, wait for the file operation to complete and eject the device. You are ready to go. The built-in speaker is good for low noise environments, but a good set of headphones will make the experience that much better.
    As stated, there is amazing codec support. If you have never used the FLAC format, it is better quality that a typical MP3, by far. As for video, AVI and MKV work flawlessly. Note: resolutions above 720p will not render well and the video and audio will almost certainly be choppy and unviewable. Another big benefit over an Apple device is that you can load media from any source. No pesky messages about your library, computer not authorized, etc.
    The only issue I run into form time to time is navigating on the touch screen. While the layout is very intuitive, I occasionally have a hard time scrolling through the media lists. Certainly the pros outweigh this.

    Final thoughts, the device size, battery life, storage capacity, and available playback formats make this an excellent device for the frequent traveler as well as the casual home user.

    Product Review: Lenovo Mini Wireless Keyboard N5091

    I have a home project to replace the DirecTV satellite boxes with PCs. So far so good. To make it easy to use I needed a wireless keyboard and mouse. The first box ended up with a Gyration Media Center Remote. For the next box I found a Lenovo Mini Wireless Keyboard with trackball. I purchased it new from the local CompUSA for less than $40.

    Upon opening the box I was impressed with the product. It fits in the hand well and is easy to use. The keyboard includes basic media player controls, essential for pausing the movie to grab another drink. Installation was a joke, plug in the micro dongle to an available USB port, install the two (included) AAA batteries and switch on the keyboard. In less than 15 seconds Windows 7 recognized the device and it began working. I removed the wired keyboard and mouse and put em back in the parts locker.

    Holding the device in the palm of my right hand I can reach most of the keyboard with my thumb. The shape makes it very comforable to hold. The small power switch is located on the underside of the device and it out of the way so it will not be accidentally shut off. Turning the keyboard will save battery life considerably when not in use. Turn the switch back on and I reconnects immediately. My typical use is from about ten feet away and it works great. Being wireless instead of infrared makes operation painless. I did some testing and was able to use over 25 feet away from the PC in a different room. Good enough for me.

    Anyone used this before? Leave a comment.

    Update: 06212011
    A couple things about this device that are lacking; 1) no backlighting of the keypad 2) no trigger finger mouse buttons 3) current trackball/mouse button configuration makes it a little difficult to ‘click and scroll’

    12/3012

    Still using this little guy. Battery life is pretty respectable. Would love to hear of any similar (read that as better) devices.

    The Beauty of Being Hardware Agnostic

    We can all agree that virtualization has numerous benefits. One of the obvious benefits is that virtualization makes systems hardware agnostic. This is one of my favorite features of going virtual. I am responsible for the network operations of many businesses and being able to forget about hardware compatibilities on the OS level is a major advantage.

    We experienced the benefits of this ourselves today while upgrading one of our servers. We added additional RAM and changed CPUs. The memory was no surprise, it is rarely an issue. When it is, it is a hardware issue not an OS one. CPU swaps are generally more complex. I have seen many Windows systems become unstable after increasing or decreasing the number of processors/cores.

    So when we got the chance to upgrade one of our ESXi servers from two dual core processors over to two quad cores we had to test it. In true anticlimactic fashion everything worked perfectly. The VMware server booted flawlessly and now shows the additional cores and RAM.

    So if you can get your hands on upgrade parts or new servers all together, go for it!

    *Update* We have since bumped the server up to 32GB of RAM, great stuff. We plan to upgrade the CPU’s again in the near future. It just keeps getting better.
