i've used only NFS and as many already found out, it can be or rather i should say, it is very unreliable.
NFS is very reliable - it just wasn't made to replace locally mounted filesystems. NFS is great, for instance, if you export a share with some files, mount it on a remote system, install the files there and then unmount the share again. If you use it to mount 200 GB in 20 filesystems to a remote system and start a database from there you are simply using the wrong tool for the wrong purpose.

Based on your experience, can you tell me what the best method of transportation is? Cars? Bikes? Aeroplanes? Rockets?
I'd say that depends: a car might get you comfortably from home to work and back, but if you want to get to the moon it is probably advisable to use a rocket instead. But if you "only" want to go transcontinental you might be more comfortable using an Airbus A340 instead of a Saturn V, etc..
Each of your mentioned methods have pros and cons and which one is the most fit for your purpose depends heavily upon what purpose that is.
How much data are talking about? Gigabytes? Some TBs? Several hundred TB, up to 1 PB?
How much bandwidth are we talking? Several high-performance real-time-processing OLTP platforms? Cloud computing?
How is this bandwidth used? Many small transactions, like a OLTP? Streams like in a streaming server? Large continuous blocksize reads/writes like a ftp-server? Small blocksize random access like the typical DB/2-LUW?
How much interoperation/data transfer is needed between the different hosts? If the answer is "very much" the answer might be "GPFS", regardless of what storae you use.
What about backup?
What about data replication?
What about snapshots?
I am sure that - off the top of my head - i didn't even ask half of the necessary questions, as others will surely point out. The list above is merely meant to show you how much questions you will first have to ask and answer before you can expect us to give you any competent advice.
I am having some NFS directory consistency problems with the below setup on a local (192.) network:
1. Different permissions (chmod) for the same NFS dir are reflected on different clients.
2. (more serious) an NFS dir created on client1 cannot be accessed on client2; this applies to some... (10 Replies)
The UPS connected to the Disk Array portion of my Windows 2003 NAS burned up over the weekend. Reconnected it to a new UPS and re-booted the NAS box. Since then I have not been able to get my HPUX 10.2 box to mount the shared drives on the NAS. At boot, the NFS client & server subsystems do a... (0 Replies)
My servers run Solaris 10. I have to move data from my NFS mount drives into the NAS storage area with all the same permissions ( for the users and programs and everything else).
Can any one help me please ??

I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)
