For anyone who lives and dies by MySQL and InnoDB, things are finally starting to heat up and get interesting. I’ve been banging the “MySQL/InnoDB scales poorly” drums for years now, and despite having paid Enterprise licenses, I haven’t been able to get anywhere. I was pretty excited when Sun …[Read more]
We bang the heck out of our IO systems here at Spinn3r so having more options is always welcome.
Bryan Cantrill, one of the original DTrace developers, worked on this bad boy so there’s obviously going to be an emphasis on performance analysis.
This is one of the main competitive advantages of the 7000 series.
Out of the box you have a full admin console for performance tuning. It doesn’t stop at just raw IOs because they’ve instrumented it with a bunch of dtrace scripts.
You can view IOPS per file, CPU, make runtime tuning and configuration changes. Basically, the entire …[Read more]
I had a very interesting conversation on the phone with
Oreland today (he also blogged about it on his blog at
There is a lot of interesting features coming up in MySQL Cluster
version 6.4. Online Add Node is one of those, which can be done
without any downtime and even with almost no additional memory
needed other than the memory in the new machines added into the
cluster. This is a feature I started thinking almost 10 years ago
so it's nice to see the fourth version of the solution actually be
implemented and it's a really neat solution to the problem,
definitely fitting the word innovative.
The next interesting feature is to use a more efficient protocol
for handling large operations towards the data nodes. This makes it
use less bits …
A compilation of today's news of interest:
Any Best poll is always subjective in one way or another, so here are two more :-) First What's the Best AppServer - with several references to GlassFish. The second is a question from a prospective GF user that elicited a Very Nice Testimonial... which is a good time for a call for Adoption Stories; if you have any, drop us a mail at stories at sun dot com.
I just bumped into the Sun BluePrints Wiki and I think it is worth a visit. It is a companion to the BluePrints Blog and part of the move towards Self-Published Content at Sun, which increases agility and responsiveness to user's needs.
The Recent Content page lists chronologically the latest changes. The more recent entries are created in Wiki format, while the earlier ones are PDF attachments.
Some of the documents that caught my attention include:
There are only two kinds of storage devices - those that have failed, and those that are about to fail. That's the view most datacenters have about the traditionally mechanical devices pejoratively referred to as "spinning rust." All disk drives fail, cheap drives fail faster.
If the average time to fail is five years, you and your laptop
can make do with the occasional backup. But when an average
enterprise has 100, or 1,000, or increasingly 10,000 or 100,000
individual disk drives, failure is a daily, if not hourly
occurrence. Mechanical devices fail.
And with failure comes the potential for losing data - using commodity disks to save your boss $500,000 does her no good if she's fined $50,000,000 for violating data retention regulations. Stock transactions, medical images or feature length movies - take your pick, some data has to be perfect. Not a decimal point or pixel out of place.
That's exactly why, years …[Read more]
Just a quick note: Kickfire is not based on SSD (solid-state device) hard drives. Their old website says “SQL goes solid state” but that just means SQL in hardware, not SSD.
When I was a child, we had a Sears Lady Kenmore clothes washing machine that boasted “solid-state circuits” on the panel, in flowery script writing. It was not based on SSD, either.
Finally, I am not on the Kickfire payroll. I’m not getting anything from working with them, except perhaps the fun of being in their labs while they’re still in stealth mode. It’s a harder balance than you might think, writing about a product that I don’t know about and am excited to learn about, and sounding objective. If I’m sounding like a fanboy, I don’t mean to. Trust me, if it’s vaporware you’ll hear it here first.
