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 […]

Percona Live MySQL Conference Sessions Announced

I’m very pleased to announce that the breakout session and tutorial schedules for the third annual Percona Live MySQL Conference and Expo 2014 are now online. The conference will be at The Hyatt Regency Santa Clara and Santa Clara Convention Center, April 1-4, 2014. I wish to personally thank our dedicated Conference Committee members who […]

More on MySQL transaction descriptors optimization

Since my first post on MySQL transaction descriptors optimization introduced in Percona Server 5.5.30-30.2 and a followup by Dimitri Kravchuk, we have received a large number of questions on why the benchmark results in both posts look rather different. We were curious as well, so we tried to answer that question by retrying benchmarks on […]

Percona Server tree with support of Fusion-io atomic writes and DirectFS

Not so long ago Fusion-io announced an SDK which provides direct API access to Fusion ioMemory(tm) in addition to providing a native filesystem (directFS) with a goal to avoid overhead from kernel and regular Linux filesystems: ext4 and xfs. This requires a support from application, it should use special calls for IO. With help from […]

Intel SSD 910 vs HDD RAID in tpcc-mysql benchmark

I continue my benchmarks of Intel SSD 910, previous time I compared it with Fusion-io ioDrive http://www.mysqlperformanceblog.com/2012/09/07/intel-ssd-910-in-tpcc-mysql-benchmark/. Now I want to test this card against RAID over spinning disks.

Intel SSD 910 in tpcc-mysql benchmark

I continue my benchmarks of Intel SSD 910, the raw IO results are available in my previous experiment. Now I want to test this card under MySQL workload to see if the card is suitable to use with MySQL. Benchmark date: Sep-2012 Benchmark goal: Test Intel SSD 910 under tpcc-mysql workload and compare with baseline […]

Testing Fusion-io ioDrive2 Duo

I was lucky enough to get my hands on new Fusion-io ioDrive2 Duo card. So I decided to run the same series of tests I did for other Flash devices. This is ioDrive2 Duo 2.4TB card and it is visible to OS as two devices (1.2TB each), which can be connected together via software RAID. […]

Testing Fusion-io ioDrive

Following my series of posts on testing different SSD, in my last post I mentioned that SATA SSD performance is getting closer to PCIe cards. It really makes sense to test it under MySQL workload, but before getting to that, let me review the same workload on Fusion-io ioDrive PCIe card. This is yet previous […]
