Here at Percona we’ve spent a lot of time improving our development and testing practices. Why? Because constant innovation keeps us ahead and more productive. We want to work smarter, not harder. One of the tools we use is the Jenkins Continuous Integration server. We use Jenkins pretty heavily to help with out development processes […]
Intel came on PCI-e SSD market with their Intel SSD 910 card. With a slogan “The ultimate data center SSD” I assume Intel targets rather a server grade hardware, not consumer level. I’ve got one of this card into our lab. I should say it is very price competitive, comparing with other enterprise level PCIe […]
I just posted this to the MySQL Internals mailing list: Hi all, Like many of you, I’m disappointed that the bzr trees for MySQL are out of sync with the tarball source and binary releases from Oracle. Since Oracle has been silent on this, and this is a recurring problem, I’ve decided to attempt to […]
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. […]
In my previous post with results for Fusion-io ioDrive we saw some instability in results, I was pointed that it may be fixed in new drivers VSL 3.1.1. I am not sure if this driver is available for everyone – if you are interested, please contact your Fusion-io support representative. I installed new drivers and […]
I still continue to run benchmarks of different SSD cards. This time I show numbers for Virident FlashMAX 1400. This is a MLC PCIe SSD device. There are couple notes on these results. First, this time I use a different server. For this benchmark it is Cisco UCS C250, while for previous results I used […]
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 […]
Following my previous benchmarks of SATA SSD cards I got Intel SSD 520 240GB into my hands. In this post I show the results of raw IO performance of this card.
Following my previous benchmark of Samsung 830, today I want to show results for STEC MACH16 SATA card, 200GB size, this card is based on SLC, and regarding STEC website, it is an enterprise grade storage.
I personally like PCIe based Flash, but from a pricing point our customers are looking for cheaper alternatives. SATA SSD is an options. There is many products based on MLC technology, and Intel 320 I would say is the most popular. I do not particularly like its write performance – I wrote about it before, […]
