When I/O latency is presented as a visual heat map, some intriguing and beautiful patterns can emerge. These patterns provide insight into how a system is actually performing and what kinds of latency end-user applications experience. Many characteristics seen in these patterns are still not understood, but so far their analysis is revealing systemic behaviors that were previously unknown.

Here are some of the folks who blog actively about storage at Oracle, listed roughly in order of popularity.
(If I'm missing someone, please let me know in the comments - more sources are always welcome!)
Jeff Bonwick - the big daddy of ZFS
BigAdmin - Rick Ramsey's funny and very useful blog about what's going on in the world of admins, which includes, of course, storage - BIG storage
Adam Leventhal - Fishworks
Oracle Solaris Video - many, many technical videos about all aspects of Solaris storage
Bizarre ! Vous avez dit Bizarre ? - Roch (rhymes with Spock) Bourbonnais : Kernel Performance Engineering. What to know how to get the best performance out of ZFS? Roch's your man.
The Observation Deck - Bryan Cantrill, one of the daddies of DTrace
Fishworks - what it says
Erick Schrock - "Musings about Fishworks, Operating Systems, and the software that runs on them"
On the Edge of the Open Storage Frontier - Tom Haynes brings 'em back alive
Dominic Kay - beneath that self-effacing British exterior lurks a man who really knows file systems
Internal Affairs - Dave Pacheco on Fishworks
Starting July 15th at 9 am (local time in Brisbane, Australia - GMT +10), we'll be streaming the Kernel Conference Australia. Go to our UStream page for the live stream and to participate and ask questions via chat.
Of particular interest to the storage crowd: Jeff Bonwick and Bill Moore on ZFS Deduplication! 9:15 am tomorrow.
Test Center: Sun's stellar NAS in a can - "...after only a few minutes of use, I was smitten. It's very attractive and very accessible. In fact, it may be the most complete filer interface I've ever seen, blowing the doors off Network Appliance's Web-based manager..." - Paul Venezia, InfoWorld Test Center
ACLs on Shares - "With build 109 of Open Solaris, a new feature has been added to the CIFS server - ACLs on Shares..." - Doug McCallum
Countdown to the OpenSolaris Storage Summit - "We're wrapping up the final details for next Monday's OpenSolaris Storage Summit and hope to see you there! We have some great talks lined up (SmugMug, GoGrid, SETI along with the latest information on Sun's Open Storage efforts) and a Community Marketplace where you can chat with companies who are part of the OpenSolaris Storage community..." - Lynn Rohrer
Not the Bandwidth... It's the Latency That Gets You - "Data needs to be stored or retrieved for devices that span from the small mp3 player to that large cloud that you provide and/or utilize. Specific to the storage of your data, performance fundamentally comes down to how you manage your reads and writes." - Bob Porras
ZFS Mandates - "While making ZFS required for court and police NAS/SAN devices it would be nice if people would use ZFS because it is so obviously better, not because its use is mandated." - Mark Musante
OpenSolaris Community Lending Project on Kiva - "...This is exactly why
global communities are valuable: people who are passionate embrace
opportunities to solve problems in new ways. If people are empowered
and able to connect, they self organize and get things done. They just
do it. So, want to help change someone`s life? Just jump right in." - Jim Grisanzio
Playing with 'sec=none' and using AUTH_NONE - "AUTH_NONE is one of the least understood security flavors you can use
with NFS (see nfssec(5) for more details). When you share a resource,
you can specify the security flavors with 'sec'. You can also specify
an anonymous uid with 'anon'. I mention that because the two interact..." - Tom Haynes
and... if you'll be in the Bay Area on Monday, February 23rd, please join us at the Open Storage Summit!
Follow the Ships in Singapore... - "Flying into Singapore, one of the worlds largest ports, I noticed something odd. There seemed to be too many ships anchored in the waters..." - Bob Porras
L2ARC Screenshots - "Back before the Fishworks project went public, I posted an entry to explain how the ZFS L2ARC worked (Level 2 Cache) - which is a flash memory based cache currently intended for random read workloads. I was itching to show screenshots from Analytics, which I'm now able to do. From these screenshots, I'll be able to describe in detail how the L2ARC performs..." - Brendan Gregg (that sexy cub)
What have L2ARC and a furniture shop in common .... - "In the last week i´ve got some questions how the L2ARC works. I thought a moment about it and came up with the following description. The whole model of caching with two layers is similar to IKEA..." - Joerg Moellenkamp
Well it jumped in priority from a P4 to a P2 and was impacting other engineers. So I thought it might be easy to dust off and finish. I was wrong..." - Tom Haynes
Sun Storage 7000 for Oracle- "Jeffrey T. Wright and Sridhar Ranganathan wrote an excellent whitepaper about the Sun Storage 7000 series for Oracle. It´s really worth a read for everybody thinking about databases on NAS: Sun Blueprint - Configuring Sun Storage 7000 Systems for Oracle Databases." - thanks, Joerg!
Sun Storage 7110 Unified Storage System - "The 7110 delivers a complete network storage solution with no hidden catches. Both NAS and IP SAN are supported, performance is very good, and Sun won't be beaten on value..." - PC Pro magazine
Sun's Open Storage play: Do unto others... - "Sun Microsystems spent a decade getting pummeled by lower-cost, commodity Linux servers. It wants to spend the next decade doing the same to its storage rivals..." - Matt Asay (thanks, Joerg!)
The OpenSolaris Bible: Hop on over to Jim Grisanzio for a full list of related links. Warmest congrats to Nick, Jerry, and Dave!
How To Build A Home ZFS File Server - ZFS Setup - Mark Musante points us to an excellent article by Jermaine Maree: "After getting the fancy new file server put together it is time to
install the operating system. There are several options, but I decided
to keep it simple and install OpenSolaris 2008.11.
The other version (there are several) that many seem to download is
OpenSolaris Express Community Edition, but it included extra
applications that I did not want. For my needs I wanted a basic OS and
planned to install the extra stuff as needed. So, what do you need to
