schoondoggy 895 Posted March 26, 2013 Share Posted March 26, 2013 Sometime ago in another thread we were chatting about builds and performance. My N40L has the stock BIOS and; 8GB of memory. HP410 RAID controller with 512MB cache. Two mirrored WD VR 250GB 10K SATA II drives for WHS2011. Four 2TB 5400rpm SATA II drives in a RAID 5 for data. USB 3.0 available via WD card IcyDock for the two mirrored drives and a BD drive. Here is the system; Performance of the mirrored pair of VR; Performance of the RAID 5 set; Very stable and functioning fine. Link to post Share on other sites
cskenney 155 Posted March 26, 2013 Share Posted March 26, 2013 Curious on thoughts why the numbers look better for the SEQ read/write in the RAID 5 vs the 2 VR mirror? Link to post Share on other sites
schoondoggy 895 Posted March 26, 2013 Author Share Posted March 26, 2013 The numbers for the mirrored pair are about the same as a single drive which is what I would expect. RAID 5 performance gets better as the number of drives increase, to a point. The RAID controller is reading and writing data from multiple drives, so sequential is easier to perform well. I will run ATTO and HD tune and see how they look. Link to post Share on other sites
schoondoggy 895 Posted March 26, 2013 Author Share Posted March 26, 2013 (edited) More benchmark data, each tool seems to represent performance differently; Mirrored pair; RAID 5: In the end, I think file transfer measurements are perhaps more meaningful. I have to wonder if the cache on the RAID controller confuses ATTO. Edited March 26, 2013 by schoondoggy Link to post Share on other sites
Joe_Miner 254 Posted March 26, 2013 Share Posted March 26, 2013 Nice looking Machine Schoondoggy! Did you have any issues with the WD card installed with the P410? With a RR2720 the WD card is not working in my N54L and when I switch out the WD USB3 Card for the Intel NIC the N54L doesn't see the RR2720 at Post. Link to post Share on other sites
ikon 439 Posted March 26, 2013 Share Posted March 26, 2013 It's a shame JM, isn't it. PCIe was supposed to resolve all these conflict issues. The cards are supposed to negotiate with the bus controller and wind up using settings that don't conflict Link to post Share on other sites
schoondoggy 895 Posted March 27, 2013 Author Share Posted March 27, 2013 I had no issues with the WD USB 3.0 card and the HP P410. The only problem I have with MicroServers is accessing the pre-boot configuration settings on LSI and Adaptec RAID cards. Seems to be a memory space issue. 1 Link to post Share on other sites
schoondoggy 895 Posted April 4, 2013 Author Share Posted April 4, 2013 (edited) The one concern with the HP P410 is that it only support SATA speeds up to 3GB, but it will do SAS up to 6GB. After some 'creative' trading my N40L now has; two Seagate Savvio 300GB 10K SAS drives mirrored for the OS and four Seagate Constellation 2TB 7200 SAS drives in a RAID 5. Performance of the mirrored SAS 10k's; Performance of the RAID 5 7200 SAS; I will be moving this storage over to the N54L when it is ready.

cskenney 155 Posted April 4, 2013 Share Posted April 4, 2013 The pictures don't show up...and links to appear to work. Edit: Appears this issue was my corporate network firewall Link to post Share on other sites
schoondoggy 895 Posted April 5, 2013 Author Share Posted April 5, 2013 The pictures don't show up...and links to appear to work. That's odd they show up for me, even when I sign out? Can anyone else see the graphics in my last post in this thread? Thanks. Link to post Share on other sites
