It just goes to show that there are a lot of different environments out there. :) You don't specify exactly what sort of environment you have, but it sounds like it's very low key. You obviously aren't concerned with heavy Internet traffic, multiuser loads, email delivery, database or CAD simulations, etc. Sure, I could see where if you just need a server to store user files, primarily documents and a small amount of email and the like, an ordinary Sun or NT server would be just fine. And since your space needs aren't as great either (generally) in such environments, you probably view disk storage very differently. >Price will probably dictate most which way we go in future and CIFS is >a big incentive but on alternate wednesdays I still favour Sun's. I'm surprised you mentioned price, since the impression I'm getting is that you wouldn't be adverse to paying more for a standard, good ol' Sun that you all know and love. But my previous guess as to your environment may be way off, so what do I know? :) >| In an odd way, since UNIX has generally done without ACLs for so long, >| most places that I know of who could use them don't, since it's not >| really necessary and it's not going to be interoperate well in a >| heterogeneous environment.

Will ACLs solve a particular problem with sharing files among users you're currently running into? Or do you plan to use it as a basis of a new file-sharing architecture? Do you anticipate any difficulty in getting users to use ACLs, and use them correctly? I haven't seen many UNIX environments heavily use ACLs, so I'm curious as to what people are envisioning. I'm familiar with how they are commonly used on the NT side, but the needs there are different. Bruce

Well, I suppose if you want access to "new" features, such as NFS v3 or ACLs, you're right - Sun tends to have them first before other vendors. However, most places I'm familiar with would rather have better performance and reliability and so on, and if that means not having NFS ACLs, so be it. In an odd way, since UNIX has generally done without ACLs for so long, most places that I know of who could use them don't, since it's not really necessary and it's not going to be interoperate well in a heterogeneous environment. So I don't know of many customers who would decide that they were going to rollout widespread ACL use and switch all of their servers over to Sun to accomodate this. Bruce

The last time the subject of ACLs came up, I sent out a message that said the following: I'd like to see them support all the different ACL types, Solaris, NT, Digital Unix, Irix, etc. (at least, I think the latter two have them) and have them all interoperate reasonably well. But that's no doubt a big undertaking for Netapp with very little return. It might make more sense is to wait on a standard ACL protocol (maybe as part of NFS v4) and then implement that and everyone will talk the same language. I hve reasons to believe the above statement is still an accurate reflection of NTAP's plans. Of course, ACLs for NT were necessary, and given the nature of the next NFS standard it may become important for them to implement Solaris ACLs as well. It will be interesting to see if they can make NT and NFS ACLs interoperate - if anyone can, I'm confident it will be Netapp. :) Bruce

ndmpc command reference
by Paul English 05 Oct '98

05 Oct '98

Can anyone point me to this? Or even how to get more than just a list of commands from within ndmpc? The documentation with the ndmpkit seems to be "specificational" in nature. The netapp website only has a couple of hints, and this list archive indicates that people use either ndmpcopy or Budtool for the most part. Specifically I need to restore some files from a library attached to the filer to an arbitrary location on a remote unix host (running ndmpd and ndmpc). This should be possible, but the example scripts and packaged documentation are not helpful at all.
