Although Intel’s Atom CPUs have made a splash in the mini ITX space, many users prefer the small form factor yet want more computing power than the Atom can muster. In response to this need, motherboard manufacturers have started to build standard socket motherboards in small form factors such as mITX.

Over the past decade, features such as video, audio, and network interfaces have moved from occupying expansion slots to being integrated directly on the motherboards. For many users onboard video, audio, and LAN obviate the need for add-on cards in a system. With all of this basic functionality onboard, smaller motherboards have become possible, such as mini ITX.

As one would gather from my previous Intel Atom D510 and NM10 post, I am not the biggest fan of the current D510 Atom platform with NM10 chipset. ZOTAC, to its credit, did take a rather mediocre platform and build a solid board around it. The most probable use case is a streaming media HTPC (non h.264) to a legacy 720p display. The nice thing about the ZOTAC offering is that it has quite a few expansion options for a D510/ NM10 based system, and it is ready to go out of the box. Unlike other Intel and AMD platforms, the Atom D510 and accompanying heatsink do not need to be installed by the user. One can literally plug in a display, mouse, keyboard, RAM, storage drive(s), and 20-pin power source and start using the system. As a preview, my end conclusion is that the ZOTAC board is a great choice given the platform, but the Intel platform leaves a lot to be desired. Continue Reading

After the Intel Xeon X3440 review, I wanted to see the difference between the X3440 and the Intel Core i7-860. Of course, I could have just purchased a Core i7-860, but instead I decided to get an Intel Xeon X3460 because it is essentially the same CPU, just with ECC support. For all intents and purposes, the Intel Xeon X3460′s performance should be identical to the Core i7-860.

The major difference between the Intel Xeon X3460 and the previously reviewed Xeon X3440 is clock speed. The X3460 runs at 2.8ghz while the X3440 runs at 2.53GHz. Price wise the 0.27ghz will cost another $120 or about 50% more depending on street price fluctuation.

To keep this comparable, I wanted to see a performance of the X3460 versus the other CPU’s I have tested for video encoding and transcoding on a Windows Home Server platform. Second, I wanted to have a server running Microsoft Hyper-V Server with Windows Home Server and Ubuntu 10.04 as guest operating systems running in Hyper-V virtual machines. In the end, I found that the Xeon X3460 was slightly faster than I had anticipated.

Intel’s 3400 chipset for its socket 1156 platform accepts CPU’s from the cheap Intel Pentium G6950 and Core i3-530 to the higher end Xeon X3430 to X3470 CPUs. Both Clarkdale and Lynnfield based CPU’s offer outstanding power consumption (for early 2010) at relatively low costs. After reviewing the Supermicro X8SIL-F, I purchased a competing (price wise) Intel motherboard to review, the Intel S3420GPLC. As I soon found, Intel also makes a good board, however it lacks some of the Supermicro’s features.

My main server, the Big WHS now houses over 60TB of storage, runs multiple VM’s, and has over 10 Gigabit NICs. At the heart of this server, is a Supermicro X8ST3-F. It was not the first motherboard I tried in the server, as I originally tried using an ASUS P6T7 WS Supercomputer in the Big WHS, but it has been running solidly since its first installation. Aside from its stability, it also comes with many PCIe slots, an onboard LSI 1068e based 8 port SATA/ SAS controller, dual Intel Gigabit NICs, onboard video, and IPMI 2.0 with KVM over IP.

As a follow-on to the Supermicro X8SIL-F review, I had some interest in seeing power consumption figures for the CPU’s involved. I have already discussed the Intel Core i3-530′s low idle power consumption and relatively low maximum power consumption extensively. As I have a habit of doing, I decided to use an Intel Xeon X3340 in the new server for two reasons. First, I wanted to see a performance of the X3440 versus the other CPU’s I have tested for video encoding and transcoding on a Windows Home Server platform. Second, I wanted to have a server running Microsoft Hyper-V Server with Windows Home Server and Ubuntu 10.04 as guest operating systems running in Hyper-V virtual machines. In the end, I found that the Xeon X3440 provides a great feature set, relatively low power consumption, and performance all at a reasonable cost.

After completing the first DAS/ SAS Expander JBOD enclosure project I realized that there was a major area of improvement. Using less than 30% of a large 4U case’s volume for useful purposes seemed like the key area to improve upon. As I was completing that build I soon realized that I wanted a secondary server to be able to access some of the drives for EXSi or Hyper-V virtual machines. Further, NAS operating systems that run poorly in virtual machines, such as unRaid require dedicated server for testing. I could have built another server in another enclosure, but I decided that I could improve upon the original design and access drives that are housed in the Big WHS ecosystem through a simple cable swap. This eliminates the need to physically move drives from enclosure to enclosure. The following is a slightly (approximately $20) more expensive version of the original Build Your Own JBOD DAS Enclosure with a HP SAS Expander iteration.

The Supermicro X8SIL-F motherboard is an excellent board for home and small business servers. When building a file server built upon Windows Home Server (V1 or V2 Vail) or another open source NAS project such as FreeNAS, Openfiler, EON ZFS storage, the Supermicro has a feature set that differentiates itself from both AMD and Intel based consumer-level motherboards. Compatibility with those operating systems and virtualization platforms such as Microsoft’s Hyper-V make the X8SIL-F a strong contender for a DIY storage or virtual machine server.

The Supermicro X8SIL-F mATX motherboard is becoming a favorite for home servers, especially those built upon Core i3′s and Core i5′s because it provides lots of expandability in a small form factor, and has IPMI 2.0. The Supermicro X8SIL-F’s supported processors can easily handle a network attached storage (NAS) virtual machine as well as additional virtual machines for other purposes. As I eluded to in my previous post, the major difference between the revision v1.01 and v1.02 boards, at least as far as I have seen, is the support for the Intel Core i3 and i5 CPU’s as well as the Intel Pentium G6950 in the v1.02 X8SIL-F versus support only for Intel   CPU’s in v1.01. With the virtualization support and hyperthreading in the Intel Core i3 and i5′s as well as the low power consumption of Intel’s 32nm process, it is a great, low cost and low power combination.

As I mentioned in the previous post on the compatibility issue, I had to RMA my Supermicro X8SIL-F (mATX LGA 1156 server board with IPMI 2.0 and dual Intel gigabit NICs) last week because it was version 1.01 PCB instead of v1.02. The difference being support for Clarkdale CPU’s.

Just to give an idea of why Supermicro’s support is so good here is the timeline:

1. Sunday (day 0) - Sent a note to Supermicro tech support explaining my problem.
2. Monday morning (day 1) - Received a confirmation that I needed v1.02 PCB of the X8SIL-F to use with my Intel Core i3-530.
3. Monday afternoon – submitted my RMA request online
4. Tuesday mid-day (day 2) - was contacted by Supermicro RMA support, I gave the requried information for advanced RMA. Later that day I got a follow-up e-mail saying that the advance RMA request had to be approved and that it may take until the next day.
5. Wednesday (day 3) – confirmed that I accepted the Supermicro advance RMA policy, and that ground shipping would be fine (I live only a few miles from a Supermicro facility).
6. Thursday (day 4) – New X8SIL-F shipped.
7. Friday (day 5) – X8SIL-F was at my doorstep. I was not home to sign for the delivery, so made arrangements to pick up at the UPS facility. Bottom line is that Supermicro had the replacement board at my doorstep within 96 hours of submitting my RMA request.

Overall great service from Supermicro! I have also decided that I will house this in the Norco RPC-4220 that serves as the DAS box for the Big WHS. That way I can use it to add drives for the test environments. Odds are I will either run ESXi with a few Linux/ FreeBSD/ OpenSolaris virtual machines or just run OSes directly on the PC. I am also planning to power this system independently of the rest of the enclosure and drives so that I can power cycle the server without taking the drives off of the Areca array.
