Linux ServerWatch writes about the slow but sure death of UNIX by the onslaught of Linux and customers moving from older proprietary UNIX systems to commercially supported open source enterprise Linux distributions. "Linux does have one killer feature that is driving the switch: lower cost. Many companies are discovering Linux to be extremely attractive from a cost perspective. Take the experience of Sabre, a travel company that replaced Solaris with Red Hat Enterprise Linux (RHEL) running on x86 machines, resulting in lowering costs 90 percent (with a three-fold speed gain to boot). These potential cost savings, which include hardware maintenance costs savings, are not to sniffed at."

No FC or multi-pathing support? Are you sure? Then how are all my Linux boxes on a fully meshed FC network going to a EMC storage array right now? It must be a miracle!

Miracle?! Linux's FC support is a nightmare: closed source drivers, binary incompatibility between minor kernel versions, vendor dependent tools, etc.

Linux needs a stable kernel ABI to be "Enterprise ready" and compete with UNIX.

No it doesn't. Vendors need to stop pushing binary blobs.

Sure I'm sure! Linux is fully dependant on FC vendor's drivers and tools, which lack performancea and are not as tightly integrated with the system. They can't compete with the support Unices have, e.g. Leadville FC stack and MPxIO in Solaris 10 which are present by default. Solaris also installs with FC drivers. (Qlogic and Emulex at least)

Running on QLogic cards with in-tree kernel drivers fine here. Multi-pathing was introduced into the stock kernel via device-mapper around 2004 IIRC.

So, it seems like you're trolling or the last time you used Linux on a SAN was pre-2004.
