There’s a dark horse coming up on the outside
Isn’t Sun – and Solaris – almost dead? No and they’re showing quite a bit of life in the storage arena. It is amazing what a $12 billion company can do with a unique strategy and deep engineering smarts.
One big change: after winning the 1.6 billion dollar anti-trust settlement against Microsoft, including a 10 year cooperation agreement, the 2 companies have embraced each other in ways – like storage – unthinkable 10 years ago.
CIFS support in the Solaris kernal
Sun’s steadily falling attach rate led me to give up on Sun as a storage vendor. But the new CEO, Jonathan Schwartz, has a new storage strategy: move storage functionality into the operating system. And there is a VP of Solaris storage software, Bob Porras.
The latest piece: CIFS. For years I’ve listened to engineers moan about the pain of implementing CIFS on non-Windows systems. Now I know why.
In a blog post Sun engineer Alan Wright explains:
There is a common misconception that Windows interoperability is just a case of implementing file transfer using the CIFS protocol. Unfortunately, that doesn’t get you very far. Windows interoperability also requires that a server support various Windows services, typically MSRPC services, and it is very sensitive to the way that those services behave: Windows interoperability requires that a CIFS server convince a Windows client or server that it “is Windows”. This is really only possible if the operating system supports those services at a fundamental level.
Solving those issues required 180,000 lines of new code in Solaris.
It gets better
They also made changes to ZFS (see my ZFS: Threat or Menace?) to support CIFS:
- Support for DOS attributes (archive, hidden, read-only and system)
- Case-insensitive file name operations.
- Support for ubiquitous cross-protocol – NFS and CIFS – file sharing.

The StorageMojo take
OpenSolaris is becoming the finest storage platform out there. Adding CIFS support to the kernal is a Big Deal: OpenSolaris will be industry’s first OSS universal storage platform.
Only a company with nothing to lose in the traditional big iron storage business could be so bold. My hat is off to Jonathan and Bob.

Comments welcome, as always. Yes, I know the Samba guys aren’t happy. One of these days I’m going to tackle the GPL vs CDDL thing and see if I can make any sense of it. I’m also wondering where all the givebacks are from the storage companies using OSS in their products.
