OpenSolaris gets CIFS

OpenSolaris, the open-source varient of Sun's Solaris, is getting an in-kernel CIFS (Common Internet File System) service. This will allow Microsoft users to store and retrieve files from an OpenSolaris system.

OpenSolaris, the open-source varient of Sun's Solaris, is getting an in-kernel CIFS (Common Internet File System) service. This will allow Microsoft users to store and retrieve files from an OpenSolaris system.

The in-kernel implementation of CIFS in Solaris will result in it gaining tight integration with NFS, ZFS and Active Directory. Why not just use Samba, you ask.

Sun's 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 inter- operability 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.

According to the Register:

Sun will incorporate CIFS Server in the 'Indiana' release of OpenSolaris, due out in the first half of 2008. It probably won't hit the commercial version of Solaris for a year or so...

So there you go. Sun is really serious about being king of the storage (and server) hill.

To my knowledge, all of the Sun systems my employer has purchased come with Solaris ( SunOS ). So where does OpenSolaris fit in? Is this an upgrade to Solaris? Thx.

. OpenSolaris is an open source operating system project based on Unix System V, sponsored by Sun, and an open source community. It is a development project, not an end-user OS product like Solaris OS or Ubuntu Linux for example. Solaris OS continues unaffected as Sun's fully supported OS product. Future versions of Solaris OS will be based on technology from the OpenSolaris project, but the two are separate operating systems. Your employer's Sun systems will continue running Solaris (unless s/he wants to enter the open source OS development business that is ;-) ). [b]More information[/b] Ultimately, Sun intends to contribute as much of the Solaris OS source code to OpenSolaris as legally possible. Some code is contributed in binary form only. Essentially, OpenSolaris is an open source development ground for Solaris that leverages the open source community model. About licensing: Most code in OpenSolaris is licensed under a Sun-authored open source license called the CDDL, a variant of the MPL (Mozilla Public License). Other code that is part of the OpenSolaris OS is licensed under other licenses (e.g. MIT, SGI Free B, FreeType). Note: The CDDL license is not legally compatible with code licensed under the GPL.
