ZFS & MySQL/InnoDB Compression Update
+0 Vote Up -0Vote Down

Network.com setup in Vegas, Thumper disk bay, green by Shawn Ferry

As I expected it would, the fact that I used ZFS compression on our MySQL volume in my little OpenSolaris experiment struck a chord in the comments. I chose gzip-9 for our first pass for a few reasons:

  • I wanted to see what the “best case” compression ratio was for our dataset (InnoDB tables)
  • I wanted to see what the “worst case” CPU usage was for our workload
  • I don’t have a lot of time. I need to try something quick & dirty.
  • I got both

    ... Syslogd and GlassFish, REST for OpenSSO, JAX-RS is final, China, SmugMug and ZFS and MySQL
    Employee_Team +0 Vote Up -0Vote Down

    A compilation of today's news of interest:

    Marco had a small expedition tracking a bug in GlassFish v2 interacting with Syslogd. He found a solution and has Posted his Story and Patches. Still working on how the fix will migrate back to the main repository.

    OpenSSO now has a set of RESTful Web Services to access its functionality to do things like authenticate, authorize, validate, etc.

    And, on the same topic, the JCP just formally announced that JAX-RS 1.0 is now final. The final specification

    Success with OpenSolaris + ZFS + MySQL in production!

    Pimp My Drive by Richard and Barb

    There’s remarkably little information online about using MySQL on ZFS, successfully or not, so I did what any enterprising geek would do: Built a box, threw some data on it, and tossed it into production to see if it would sink or swim.

    I’m a Linux geek, have been since 1993 (Slackware!). All of SmugMug’s datacenters (and

    Innovation Loves a Crisis

    I thought I'd share a note I sent earlier in the week to Sun's leaders - about the turmoil we're seeing in the markets, and how I want our team focusing their efforts.

    Saving a Fortune in Data Warehousing
    Employee +0 Vote Up -0Vote Down
    UPDATE at bottom.

    I just wanted to extend my congratulations to the team at Greenplum, and our joint customers at Fox Interactive Media - the folks behind MySpace, Photobucket, IGN, FOXSports.com, and a whole series of web properties that together represent one of the single largest audiences on the web.

    All three of us announced today that Fox is running a massive production data warehouse built atop Greenplum's data warehousing software on Sun's Solaris/ZFS based OpenStorage platforms (a sea of Thumpers, to be specific). That is to say, open source software

    ZFS with Cloud Storage or Faraway Storage
    Employee +0 Vote Up -0Vote Down

    Recently I am been testing few pieces of Storage projects of OpenSolaris with PostgreSQL. One of tests involves using an iSCSI disk  with PostgreSQL.  Unfortunately the storage that's available is  in Colorado  while my PostgreSQL server is  located in Massachusetts. Latency will definitely be one of my top problems since storage  is halfway across the country (in Colorado). Plus the fact that I will be running a database server on my end  doesn't really sound like a good idea. Come to think about it, this could be a more common problem nowadays since Cloud Storage (for example Amazon S3 Webservice ) could be  optimistically  half way across the country and pessimistically be on the other side of the world.

     So what are my options to solve such

    Fanning the Winds of Change in Storage
    Employee +0 Vote Up -0Vote Down
    It's been over a month (and three hurricanes in America) since I've posted a blog. More than a few of you've noticed - thanks for the prodding...

    It's been a busy summer, on nearly every front. Customer activity hasn't slowed down, and the good news surrounding the (otherwise unfortunate) economic crisis embroiling many customers (especially those in the financial services industry, a heavy concentration for Sun) is that it's whipping up the winds of change. Customers facing spending pressure, or tiring of vendor price increases have new options, and there's a new appetite to explore those options (nothing like mandates from the CEO to reduce spending by 50%).

    One of my more interesting recent meetings wasn't with a customer, though, it was with an equity analyst from a global financial institution. Equity

    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.

    Talking with Zmanda's CEO, Chander Kant

    At the Red Hat Summit I was able to grab sometime with Chander Kant, CEO of open source back-up provider, Zmanda.

    I had previously met Chander at the MySQL conference where they were named a partner of the year, but we didn't get a chance to talk much.  It was pretty cool to hear about how he originally identified the opportunity for Zmanda and then built a business around it.

    Snow Leopard to have ZFS
    +0 Vote Up -0Vote Down

    The next release of Mac OS X, Snow Leopard, will have ZFS enabled by default. There’s a good article for the masses, at ZDNet on ZFS on Snow Leopard - do read it.

    We all know running any form of server using HFS+ tends to be a bit of a joke. So, Snow Leopard Server will be where ZFS makes its debut. It won’t be long before regular users will want it in their Mac Pro’s and so on…

    OS X as a deployment platform for production MySQL servers? This is not far off, I’m sure.

    Anything But a Flash in the Pan
    Employee +0 Vote Up -0Vote Down

    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

    OpenSolaris, Amazon, MySQL and Glassfish... Clouds Parting
    Employee +0 Vote Up -0Vote Down
    We made some big announcements this week at our annual developer forums, CommunityOne and JavaOne. I thought I'd highlight a couple in particular.

    We announced the first commercial release of OpenSolaris - targeting high speed developers and development teams (not consumers...). OpenSolaris focuses on developers wanting to be freed from proprietary software models, who see innovation and automation in operating systems as a source of competitive advantage.

    If Solaris 10, OpenSolaris's older brother, is for IT departments prioritizing carrier grade stability over rapid innovation, OpenSolaris targets the exact opposite - developers, from high performance computing to social networking, that prioritize a constantly refreshing repository filled with community innovations (and ZFS-based automated

    Sun's exciting technologies
    +0 Vote Up -0Vote Down
    It's exciting to see how many technologies Sun is working on.

    On May 1, I took a few members of our operations and database team to meet with Vasu Prakash who is an Engagement Architect with Global Systems Engineering division of Sun Microsystems. Vasu generously let us pick his brain regarding a wide range of exciting technologies Sun is working on and to see how they may potentially address our needs and challenges.

    The following notes are my personal notes expanded with some articles from my bookmark collection.

    - Thumper (X4500) offers 48TB (SATA HDD) in a 4U at around $1.30/GB, runs Solaris OS and ZFS and supports RAID 0, 1, 0+1, 5, 6 enabled by RAID-Z and Raid Z2. X4500 supports 16GB RAM and needs 200-220 V AC for power. For non-Solaris users, other operating

    ZFS Puts Net App Viability at Risk?
    Employee +0 Vote Up -0Vote Down
    About a month ago, Network Appliance sued Sun to try to stop the competitive impact of ZFS on their business.

    I can understand why they're upset - when Linux first came on the scene in Sun's core market, there were some here who responded the same way, asking "who can we sue?" But seeing the future, we didn't file an injunction to stop competition - instead, we joined the free software community and innovated.

    One of the ways we innovated was to create a magical file system called ZFS - which enables expensive, proprietary storage to be replaced with commodity disks and general purpose servers. Customers save a ton of money - and administrators save a ton of time. The economic impact is staggering - and understandably threatening to Net App and other proprietary companies. As is all free innovation, at some level.
