Percona Server with TokuDB: Packing 15TB into local SSDs

Two weeks ago we released an Alpha release of Percona Server with TokuDB. Right now I am on a final stage of evaluation of TokuDB for using in our project Percona Cloud Tools and it looks promising.

Inexpensive SSDs for Database Workloads

The cost of SSDs has been dropping rapidly, and at the time of this writing, 2.5-drives have reached the 1TB capacity mark.  You can actually get inexpensive drives for as little as 60 cents per GB. Even inexpensive SSDs can perform tens of thousands of IOPs and come with 1.5M – 2M hous MTBF and […]

Testing Intel, Samsung & SanDisk SATA SSD

While working on the service architecture for one of our projects, I considered several SATA SSD options as the possible main storage for the data. The system will be quite write intensive, so the main interest is the write performance on capacities close to full-size storage. After some research I picked several candidates (I show […]

On SSDs – Lifespans, Health Measurement and RAID

Solid State Drive (SSD) have made it big and have made their way not only in desktop computing but also in mission-critical servers. SSDs have proved to be a break-through in IO performance and leave HDD far far behind in terms of Random IO performance. Random IO is what most of the database administrators would […]

MySQL and SSD | Percona XtraDB Cluster talks

On Percona Live New York I’ll be giving two talks “Percona XtraDB Cluster: HA solution for MySQL”. I will give introduction in MySQL clustering and show how Percona XtraDB Cluster solves HA and scalability problems. MySQL and SSD: usage and tuning. If you follow this blog, you know that I do quite a bit experiments […]

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.percona.com/blog/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 Intel® SSD 910

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 […]

Intel 520 SSD in MySQL sysbench oltp benchmark

In my raw IO benchmark of Intel 520 SSD we saw that the drive does not provide uniform throughput and response time, but it is interesting how does it affect workload if it comes from MySQL. I prepared benchmarks results for Sysbench OLTP workload with MySQL running on Intel 520. You can download it there.

Webinar: MySQL and SSD

Just as a reminder – tomorrow, May-9, 2012, at 11am PDT I will be giving a free webinar “MySQL and SSD”. This is the same talk I gave on Percona Live MySQL Conference, so if you were there – you probably will find nothing new. Otherwise, you are welcome to join!
