FusionIO 320GB MLC random write performance

I was advised that new drivers and new firmware for FusionIO cards improve performance and stability and it is recommended to review results I’ve got about year ago. Using the same methodology and the same box as for Intel 320 SSD, I run random writes benchmarks for FusionIO 320GB MLC card (I do not have […]

FlashCache: tpcc workload with FusionIO card as cache

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 […]

RAID throughput on FusionIO

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 […]

fsyncs on software raid on FusionIO

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 […]

How many fsync / sec FusionIO can handle

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:

So that’s 9229.35 req/sec, which is pretty impressive. For comparison the same […]

FusionIO 320GB MLC benchmarks

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, […]

Redis Benchmarks on FusionIO (Round 1)

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.

FusionIO – time for benchmarks

I posted about FusionIO couple times RAID vs SSD vs FusionIO and Testing FusionIO: strict_sync is too strict…. 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 […]

Testing FusionIO: strict_sync is too strict…

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 […]

RAID vs SSD vs FusionIO

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 […]
