I have experience with FAS 3050, each has single controller. We use two such filers, and configured them as active/active HA 2-nodes cluster. Now, as I understand, with FAS 3200 series, for instance, FAS 3250, each has 2controllers, and one filer itself can be configured  as active/active. Would you please tell me differences between these two situations and using 2 different  storages, one is using two Filers, the other is using one single filer and 2 controllers? Thanks a lot for your advice in advance! ... View more

I'd like to get a concensus advise on what the real network speed should be, in order to setup a snapmirror sync mode between two sites and in a real Oracle database production environment?   as i understand, sync mode requires low latency, and quick response from the remote site, otherwise, the performance on primary production will get effected. so, in your environment what is your network speed?   My additional question is, how Snapmirror can ensure the database consisitency? since when snapshot is being taken during the snapmirror, the database is still in write mode, not in a backup mode?   Thanks for your information! ...

We are comparing the disk performance between internal drives and NetApp luns on HPUX servers. Could anybody please let me know what commands or tools to make such comparison. I'd assume these tools/commands have to be running on HPUX. OnTap 7.3.7 HPUX 11iv3 Thanks! ... View more

we export a NFS VOLUME to a HP-UX and a Linux server. oracle uid and gid has different values on these two NFS clients. now, files are created on hpux by oracle have ownership of "oracle:dba", however, on the linux server, the ownership on the same file appears to be two values, for instance "1000:1001" for uid and gid on linux. i tried "-sec=sys,rw,anon=0,nosuid", and also a lot of other possible combinations. Is there anyway I can get this issue resolved, other than change uid and gid on one of clients? Thanks, ... View more

We are planning on writting large amount of data over HPUX nfs client, and then remount the NetApp NFS server over to a Linux client, using the same data. Can that be done? Can two different clients use the same data on NetApp? OnTap ver 7.3.2 Please advice. Thanks! ... View more
