On SSDs – Lifespans, Health Measurement and RAID
+4 Vote Up -0Vote Down
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 be concerned about as that is 90% of the IO pattern visible on database servers like MySQL. I have found Intel 520-series and Intel 910-series to be quite popular and they do give very good numbers in terms of Random IOPS. However, its not just performance that you should be concerned about, failure predictions and health gauges are also very important, as loss of data is a big NO-NO. There is a great deal of misconception about the endurance level of SSD, as its mostly compared to rotating disks even when measuring endurance levels, however, there is a big difference in how both SSD and HDD work, and that has a direct impact on the endurance level of SSD.

On July 15th and 16th I will be in San Francisco for a few meetings, and it will be my pleasure to meet the San Francisco MySQL User Group, where I will talk about MySQL Sandbox.
From there, I will continue to Portland, to attend the Community Leadership Forum and, of course OSCON, where I will have three talks: two in the main event, and one at the Intel booth.

A Spring in its step
SpringSource boasted of rapid revenue growth while CEO Rod Johnson claimed that Red Hat’s Open Choice initiative is defensive response to SpringSource, a suggestion that was denied by Rich Sharples.

Freeloaders, leeches and hermits

I already provided my views earlier this week on Infoworld’s report about open source ‘leeches’ and corporate contributions. The debate continued as Dave Rosenberg clarified his position, and Tarus Balog gave his

Cloudera shows signs of progress

GigaOM reported that Cloudera raised $6m Series B funding from Accel and Greylock and is now looking beyond web applications to wider enterprise adoption of Hadoop. Cloudera also announced its first certification program for Hadoop.

HP Joins Solaris Community (Live Free or Die)
Employee +0 Vote Up -0Vote Down

In 1809, a hero in America's Revolutionary War, General John Stark, was forced to decline an invitation to a military reunion due to ill health. He sent a toast to be read in his absence that began, "Live Free or Die." That phrase is now the official motto of the American state of New Hampshire (where Stark lived), known for a fierce sense of independence (and no income taxes).

Hold that thought for a moment.

IT giants in open source for competition, cash

I spent part of yesterday attending the Open Source Summit at Portland’s Innotech Business and Technology Conference, and moderating a panel on ‘IT Giants and Open Source.’ We had a great discussion about the reasons, roles, responsibilities and rewards for big vendors to be acutely and adequately participating in open source software development and commercialization. Our fabulous panelists were Danese Cooper, open source diva, knitting machine and present to give perspective from Intel, Stuart Cohen of OSDL fame and current leader of startup CSI and

Servers are too fast!
+0 Vote Up -0Vote Down

We got a couple of new servers at Solfo recently which showed me one of the reasons virtualization is so popular now: Servers are too fast!

The "standard issue" CPU is now a quad-2.5GHz CPU, so in each server we have 20 GHZ CPU and 32GB ram (at less than $50 per gigabyte it's too cheap to not just fill it up and be done upgrading). Just a few years ago the CPUs we were getting were "only" dual 2GHz, for ~8GHz CPU per box. That's a big increase!

In each "tier" of the application (app servers, db servers, search servers) our main reason for having more than one or two servers is redundancy / high availability - never lack of CPU and rarely because we need more memory.

Here's from one of our webservers (virtualized with Xen with 6 of the 8 CPUs on the "real" hardware).
