I have posted results for FusionIO 320GB MLC on our ssdperformanceblog.com blog. To not duplicate content, there is link on original post:http://www.ssdperformanceblog.com/2011/06/fusionio-320gb-mlc-random-write-performance/ Follow my twitter Follow @VadimTk for further results.
This run is very similar what I had on Intel SSD X25-M card, but now I use FusionIO 80GB SLC card. I chose this card as smallest available card (and therefore cheapest. On Dell.com you can see it for about $3K). There is also FusionIO IO-Xtreme 80GB card, which is however MLC based and it […]
Along with maximal possible fsync/sec it is interesting how different software RAID modes affects throughput on FusionIO cards. In short conclusion, RAID10 modes really disappoint me, the detailed numbers to follow. To get numbers I run
test with 16KB page size, random read and writes, 1 and 16 threads, O_DIRECT mode. FusionIO cards are […]
As soon as we get couple FusionIO cards, there is question how to join them in single space for database. FusionIO does not provide any mirroring/stripping solutions and totally relies on OS tools there. So for Linux we have software RAID and LVM, I tried to followup on my post How many fsync / sec […]
I recently was asked how many fsync / sec ( and therefore durable transactions / sec) we can get on FusionIO card. It should be easy to test, let’s take sysbench fileio benchmark and run, the next command should make it:
./sysbench --test=fileio --file-num=1 --file-total-size=50G --file-fsync-all=on --file-test-mode=seqrewr --max-time=100 --file-block-size=4096 --max-requests=0 run
Operations performed: 0 Read, 922938 Write, 922938 Other = 1845876 Total
Read 0b Written 3.5207Gb Total transferred 3.5207Gb (36.052Mb/sec)
9229.35 Requests/sec executed
So that’s 9229.35 req/sec, which is pretty impressive. For comparison the same […]
After my previous benchmarks of FusionIO 160GB SLC card, FusionIO team sent me for the tests another card, FusionIO 320GB MLC. I should say I really appreciate an opportunity to play with this card and with combination of two cards. This card is also not cheap, the price I can find on dell.com is $6,829.99, […]
Peter took a look at Redis some time ago; and now, with the impending 1.2 release and a slew of new features, I thought it time to look again.
I posted about FusionIO couple times RAID vs SSD vs FusionIO and Testing FusionIO: strict_sync is too strictâ€¦. The problem was that FusionIO did not provide durability or results were too bad in strict mode, so I lost interest FusionIO for couple month. But I should express respect to FusionIO team, they did not ignore […]
With new updates of FusionIO drivers I was able to test it on our Dell R900 with Ubuntu 8.10 without pain of compiling drives myself and downgrading to older kernel, so I was decided to test it in strict_sync mode. As I understand FusionIO in default mode, like Intel SSD, is “lying” to application, and […]
In benchmarks passion (see my two previous posts) I managed to setup all three devices (RAID was on board; Intel X25-E SSD connected to HighPoint controller, FusionIO card) on our working horse Dell PowerEdge R900 (btw, to do that I had to switch from CentOS 5.2 to Ubuntu 8.10, as CentOS was not able to […]
