File Server Benchies

[lcdguy]

as some may have seen i recently built a new file server. these are the results on running on 8 drives.

here are the benchmarks i ran on my 8 disk raid 10 array in HDtach, Hdtune, and iometer.

First up for hd tach and hdtune is my boot drive. it's a quick little sucker (it's a laptop HDD) These tests were performed with the following settings.

HD Tach - Long 32MB test
HD Tune - Size 8MB, Accuracy around 75%
IO Meter - Queue Depth was set to 8 with one test set to 4, 256KB since that's my stripe size. with varying rations as indicated below.





Next up is the Raid array. Also the iometer tests were only run on the raid array.





IOMETER RESULTS

QD - 4
Sequential/Random - 95/5
Read/Write - 50/50
256KB


QD - 8
Sequential/Random - 95/5
Read/Write - 50/50
256KB


QD - 8
Random/Sequential - 100/0
Read/Write - 100/0
256KB


QD - 8
Random/Sequential - 100/0
Read/Write - 0/100
256KB


QD - 8
Random/Sequential - 0/100
Read/Write - 100/0
256KB


QD - 8
Random/Sequential - 0/100
Read/Write - 0/100
256KB


And that's only running on 8 disks/spindles. I can't wait to run this test again later in the year when i have all 24 bays populated.

whats up with access times? :)

you must mean the spikes. well you do realize that i was testing with a queue depth of 8 right. that's not too bad. some are worse than others but that's mostly because i am firstly using consumer grade drives not true SAS drives and secondly my raid card is an entry level card.

[lcdguy]

ok then take your raid. install iometer and run the same tests as me with a queue depth of atleast 8 and well see how it holds up.

oh.. must be a HD Tach (free version) bug... it's actually much bigger than 2TB
