    For all ECC skeptics

    I just found the following entry in my kernel log. First time I have seen such report across several systems. And I live at only 517 m above sea level. The error is in the IPMI log, too. [133651.455223] {1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1...

    MiniSAS reverse fan-out cables with sideband

    There are certain mainboards (like the new X10SL7-F) that have 4x SATA connectors and a SGPIO sideband header (SFF-8448). If I wanted to connect that to a MiniSAS backplane and still use the sideband signals to control the fail LEDs, I would need a reverse breakout cable with a sideband...

    New ZFS pool - some questions

    I'm currently in the process of converting my main storage pool to ZFSonLinux. I finally (almost) decided that I would like to have an 11 disk RAIDZ3 pool over a 10 disk RAIDZ2 and 2x6 disk RAIDZ2 pool. My question however is: wouldn't it be better to create the pool with ashift=13 (yes...

    10Gb direct link & routing

    Recently I got two Intel X540 for a direct connection between my fileserver (Linux) and my desktop (Windows 8). I would like to configure both computers in way that they transparently prefer the fast link over the normal gigabit links to the switch, but only for communication between those two...

    SRT cache on larger SSD & TRIM

    I currently use a 256 GB SSD for OS and applications and a 64 GB SSD as SRT cache for a 3 TB HDD. This enables TRIM for the primary SSD. Since I will not fill the 256 GB SSD anytime soon I was thinking about using the 64 GB SSD otherwise and just using the 256 GB with a small cache and the...

    SSDs and their write cache

    With vendors like LSI offering RAID solutions specifically for SSDs like FastPath, the question rises if it makes sense to combine a battery or flash backed RAID controller with an SSD with unreliable write cache. A lot of consumer drives seem to ignore the write cache settings and use it...

    Convert Windows 8 from UEFI to BIOS

    I tried several weeks to get my P8Z77 WS to boot per UEFI from a QLE2560 FC controller and an X540-T2 per iSCSI (both work with BIOS boot). It just does not work. It seems to be an incompatibility between the board's implementation and the UEFI option ROMs on the controllers. In the mean time I...

    LSI MegaRaid and write-back caching for passthrough devices

    I'd like to know if the LSI MegaRaid controllers, specifically the 9271-8i, can do write-back caching for passthrough devices. I read that JBOD mode has to be specifically enabled for the controllers and then for the specific devices. I fear that I would lose the write-back caching feature in...

    Tool for block/sector level copy of raid drive

    I need a tool that runs under Windows 2008 R2 and is able to do a 1:1 block level copy of a 3 disk RAID 5 on a Dell Perc 6/i controller. The controller dropped two disks (Seagate 7200.11) a few days apart. While the disks are basically scratch disks for numerical simulations some users did not...

    DDR3-1600 on GA-P67A-UD4-B3

    I currently try to get a 4x4GB Corsair Vengeance DDR3-1600 kit running at 1600 MHz with an i7-2600K on a Gigabyte P67A-UD4-B3 board. Sadly, it seems 1600 MHz is not Prime-stable, the test fails after minutes. The memory runs stable 1333 MHz, however. Are there some specific things I can try...

    Disable onboard buzzer on MSI H55M-E33

    Is there a known way to disable the onboard buzzer on the H55M-E33? I'd like to use that board for my HTPC and the power-on beep annoys me. There is no BIOS option and no comment about that in the manual. Maybe there is an undocumented jumper setting to diable it, because my next step would be...

    Scythe Mine 2 vs. Prolimatech Genesis

    I'd like to hear some opinions on which of those coolers I should use for my i7-2600K in a FT02 case. I already have both, it is just the question which goes into which case. While the Mine 2 would better fit into the airflow in this specific case, I cannot use two fans like for the Genesis as...

    Radeon stereoskopic 3D solution

    I plan to upgrade my HD 5850 setup and I'm considering either a GTX 580 or HD 6970. The GTX 580 is either extremely expensive here (500€+) or nearly impossible to get at the moment so I'm leaning towards the AMD card. Is there a viable 3D shutter solution available to use with AMD cards...

    Looking for some display suggestions

    I plan to replace my two SyncMaster 940BF 19" displays I used for around 8 years. While I planned to get a single 30" display I delayed that purchase because of several reports of sparkling ag coating issues. At first I thought that that would not be an issue for me, but I recently bought an...

    HDD or SSD for swap-heavy system

    I have a 16 GB UP Xeon workstation with Windows 2008 R2 server that constantly uses like 20-25 GB of overall memory and as a result is doing some heavy swapping. A RAM upgrade is out of question here. Currently the pagefile is on the same disk as the OS and the software running can generate...
