April 26, 201610 yr Hello, Was wondering if anyone is running SPF+ Ethernet Adapter cards in there unraid server? I have a switch with the ports and was looking at getting card to hopefully use to get a nice 10g connection. I am new to using these type of network adapters so any advice would be welcome. Here is the card & cable I was thinking of getting: http://www.ebay.com/itm/131635130770 Thanks
April 29, 201610 yr I've been running Connectx-2 EN cards for a while. The drivers are already in unraid and they are dirt cheap on ebay.
November 30, 20169 yr Author Sorry for the delay kids and the holidays take up alot of time. So I have the network setup and it looks like both Unraid servers are seeing the hardware just fine. All the other computers are seeing the server to. The problem I am now having is that if I am moving files from one server to the other (SMB mounted share) with MC I am only getting about 40MB/s. Am I missing something? Shouldn't it be faster then that?
November 30, 20169 yr Author Sorry its going Unraid to Unraid and from array share to array share. All HDD and I do not have cache drive setup right now.
November 30, 20169 yr That's typical speed for parity writes. Writing to the parity array requires reading parity and reading the data to be written, calculating the parity change from the data change, then writing data and writing parity. There is also a "turbo" (reconstruct) write mode that calculates parity by reading all other drives then writing data and writing parity. See here.
November 30, 20169 yr Sorry its going Unraid to Unraid and from array share to array share. All HDD and I do not have cache drive setup right now. Like trurl mentioned that is the normal writing speed to the protected array in non turbo mode, gigabit is enough for that. 10GbE is good especially for SSD transfers and for read speeds from the array, as modern disks can do ~200MB/s on the outer cylinders. Make sure you enable direct_io (settings -> global share settings), makes a big difference for user shares read/write speed.
November 30, 20169 yr Author Wonderful, I just wanted to make sure I wasn't missing. I will look into the direct_io when I leave work Thank you
