Virident vCache vs. FlashCache: Part 2
+1 Vote Up -0Vote Down

This is the second part in a two-part series comparing Virident’s vCache to FlashCache. The first part was focused on usability and feature comparison; in this post, we’ll look at some sysbench test results.

Disclosure: The research and testing conducted for this post were sponsored by Virident.

First, some background information. All tests were conducted on Percona’s Cisco UCS C250 test machine, and both the vCache and FlashCache tests used the same 2.2TB Virident FlashMAX II as the cache storage device. EXT4 is the …

Virident vCache vs. FlashCache: Part 1
+0 Vote Up -0Vote Down

(This is part one of a two part series) Over the past few weeks I have been looking at a preview release of Virident’s vCache software, which is a kernel module and set of utilities designed to provide functionality similar to that of FlashCache. In particular, Virident engaged Percona to do a usability and feature-set comparison between vCache and FlashCache and also to conduct some benchmarks for the use case where the MySQL working set is significantly larger than the InnoDB buffer pool (thus leading to a lot of buffer pool …

I actually was not aware about any real names at that time, it was just a guess, as PCI-E market is really attractive so FusionIO can't stay alone for long time. So I am not surprised to see new card provided by …

The EC is mostly, but not entirely, wrong about Oracle/MySQL
+2 Vote Up -0Vote Down

By now you are probably aware that the European Commission has decided to launch an extended investigation into Oracle’s acquisition of Sun based on concerns over MySQL.

The new has prompted a lot of criticism of the EC, much of it suggesting that the delay will do considerable harm to Sun (and therefore Oracle). This argument is valid - Sun’s already declining revenue has been in freefall since the deal was announced and one wonders how far it will fall in another 90 days of stasis.

The commercialisation of Memcached
+0 Vote Up -0Vote Down

There has been a significant increase in interest in the Memcached, the open source distributed memory object-caching system, in recent months, as a number of vendors look to exploit its popularity in Web 2.0 and social networking environments.

Like Hadoop, which has become the focus of a number of commercial plays, it would appear that the time is right for commercialization of Memcached. But what is it, here did it come from, and what are the chances for vendors to rake in serious cash? Here are the details.

What is it?
Pronounced mem-cash-dee, Memcached was originally created by Danga Interactive (the …
