    DrivePool and Scanner in a separate box connected with SAS cables

    in Hardware

    Posted

    I used this adapter cable for years & never had a problem. Before I bought my server case I had a regular old case. I had (3) 4 in 3 hot swap cages next to the server. I ran the sata cables out the back of my old case. I had a power supply sitting on the shelf by the cages which powered them.

    The cool thing was that I ran the power cables that usually go to the motherboard inside of the case from the second power supply. I had a adapter that would plug into the motherboard and the main power supply that the computer would plug into. The adapter had a couple of wires coming from it to a female connection. You would plug your second power supply into it. 

    What would happen is that when you turn on your main computer the second power supply would come on. That way your computer will see all of your hard drives at once. Of course when you turned off your server both of the power supplies would turn off.

    Here is a link to that adapter. Let me know what you think.

    Recomendations for SAS internal storage controller and configuration

    For these two cards, you want the 9207-8i.  It's PCIe 3.0, whereas the 9211-8i is PCIe 2.0.  That means more bandwidth.  Not that it actually matters, since the 2.0 version can get 15-20 disks at max speeds before bottlenecking. 

    They're meant to be run in a server chassis, where the fan setup in the case takes care of that.   So if you're not doing that, then yes, you want to add some cooling, too. 

    This are wrong.  I can dig up the links, but there are a number of flawed assumptions that these articles are making that undermine their entire argument. 

    You can go that route too.  But there are also SAS Expanders (like the Intel RES2SV240) which hook up to one of the SAS ports, and let you hook up 20 more drives.   

    This is basically what I do, and have about 30 drives hooked up to a M1115 (flashed with the 9211-8i firmware). 

     

    I can attest that the above works. I purchased a Norco RPC-4216. This is a 16 bay case a year ago. I purchased the LSI SAS 9207-8i card. I have it hooked up to the Intel RES2SV240 Expander card. All 16 hard drives run at full speed with this setup. It is a little slow to boot, the card takes a few minutes to initialize. But once the machines boots up it is a screamer.

    New Scanner Will Not Read NVME PBX Smart

    It was actually easy to upgrade. I downloaded the Media Creation Tool from Microsoft.

    I opted to save the files as a ISO. I extracted the files from the ISO into a install directory on my NVMe drive. Then typed setup.

    It installed Windows 10 Pro since I was upgrading from Windows 8.1 Pro. Once the upgrade was completed Windows activated itself. I wasn't prompted for a product key or anything. So it looks like you can still get the upgrade for FREE! I'm not complaining.

    I hope this info can help someone else get a free copy of Windows 10.

    Drivepool will not balance

    in General

    Posted

    I've been having a problem with my Pool not balancing. I am running version 2.2.0.903.

    Each time I try to manually balance I get the following error code in my service log:

    0:09:59.6: Warning: 0 : [Rebalance] Error balancing. The system cannot find the path specified

    Any help would be appreciated in this manner.

    Thanks

    Phil
