Wimpie Posted December 1, 2017 Share Posted December 1, 2017 (edited) This MB has everything I want (not necessarily need ). - 10 G SFP+ - enough horsepower to run some dockers - enough PCIe slots for a 24+ drive array (build in LSI2116 helps) - max speed for parity check/rebuild (I hope) - IPMI But I have some questions about it. Hopefully someone else has one and can help me... Is the onboard LSI2116 in IT mode, or do I have to reflash it? Is it possible to reflash this controller to IT mode? Has someone got one of these in use with a large array? Does the parity get slowed down (by an internal bus-limit)? I have some A1SAM-2550F MB's, but those are clearly limited by an internal bus. I get only 50 Mb/s per drive with a full array (24 drives). Would the X10SDV-2C-7TP4F also be quick enough to have full parity check speeds? This is a pentium CPU. Does it have the same internal DMI2 bus like the D1518 has? It would be the above motherboard or this: - X11SSH-CTF (but I like SFP+ more than 10GBase-T, also not much 'spare' PCIe capacity, LSI3008 just 8 drives compared to the other MB) - Xeon E3-1230V6 (50% quicker than the Xeon D-1518, internal DMI3 bus) Can someone help me decide?

Gico Posted December 7, 2017 Share Posted December 7, 2017 I have this (X10SDV-4C-7TP4F) board with a 10 disks array, not including cache. You can get descent speeds: Following is my parity checks history. I don't know why the speed vary, but I guess the maximum reading is the minimum limit this board might have. 2017-10-24, 14:24:17 1 day, 12 hr, 54 min, 12 sec 75.3 MB/s OK 2 2017-05-27, 00:50:51 15 hr, 13 min, 14 sec 182.5 MB/s OK 0 2017-04-04, 16:36:18 22 hr, 18 min, 11 sec 124.6 MB/s OK 0 2017-02-20, 05:24:08 18 hr, 41 min, 21 sec 89.2 MB/s OK 0 2017-01-03, 06:24:40 15 hr, 1 min, 23 sec 111.0 MB/s OK 2016-12-06, 11:03:25 15 hr, 26 min, 56 sec 107.9 MB/s OK 2016-11-13, 20:35:01 14 hr, 52 min, 27 sec 112.1 MB/s OK Aug, 03, 17:34:46 14 hr, 44 min, 26 sec 113.1 MB/s OK Jun, 04, 21:18:19 9 hr, 49 min, 39 sec 169.6 MB/s OK Quote Link to comment
Wimpie Posted December 16, 2017 Author Share Posted December 16, 2017 Thanks for the history, Gico. It doesn't seem to have hit an internal bus limit with 10 drives, hoping it's also not visible with 24 drives. I'll be ordering one in januari... Quote Link to comment
