Although skeptical about it going into the project, I've deployed a virtualized oracle rac environment over 10G NFS and with some tuning it was stable and performant. If it is good enough for rac, which has some of the most stringent latency / performance requirements that I've seen, I'd say that it is probably good enough for quite a few production use cases, although to be fair this was only an 8 node cluster.
- throwaway1979 12y agoSome naive questions if you don't mind... (I'm really curious about RAC .. my only DB experience has been small MySQL and MS SQL Server clusters). 1) I thought the really high end DBs like to manage their own block storage. Your NFS comment suggests that the database data files were running on an NFS mount, and you had a 10 gig Ethernet connection to the file server. 2) What would you say is the average size of a RAC cluster in (your opinion)? Is 8 considered a small cluster in this realm? 3) DBs have stringent requirements when it comes to operations like sync. Can you actually get ACID in an NFS backed DB? Thanks for satisfying my curiosity :)
- jsmeaton 12y agoJust to offer a little bit of information, we're currently running a 2 node RAC cluster. I'm not entirely sure about the storage mechanism though.
