JGPSH - Looking through in ZExplore I don't find anything in the DFM 5.2 or 6.0 APIs to do this. I haven't looked at 6.x, but the auto discovery option in earlier versions of OCUM allowed for periodic re-scan of the network for new storage systems. I hope this response has been helpful to you.

Joe - Given the compression on the NetApp there isn't much room for the Riverbeds to do further optimization. You may save some CPU on the filers by turning off the compression and let the Riverbeds do the work. Snapmirror over multiple connections may be configured as single or multi mode. Multi gives increased bandwidth using both connections. Single gives failover in the event of primary path failure. I hope this response has been helpful to you. At your service, Eugene E.

Joyce - Given that I'm teaching MetroCluster for a client in India this week this post realy caught my attention ! Best guess is that there was an unkown failure of the cluster, and the systems weren't sure of the state before the failure. It was probably a check to prevent a bad resync if there was a split brain scenario. I'd want to check the logs on both sides of the cluster to see what happened before the break. I probably would have isolated the down system and done this before proceeding with bringing the failed node back online. Thank you for this timely question. I'll probably use it as a teaching example in the morning. I hope this response has been helpful to you. At your service, Eugene E.

Gmillazzoitag - I'm sorry you felt it was 'advertising' for FastLane, it wasn't meant to be. I promote NetApp training from all NetApp U vendors. You may notice I teach for several of them worldwide. A point I didn't make in my previous response was that the Oracle on NetApp course has been re-written recently for ONTAP Cluster-Mode. It includes extensive labs using Cluster Mode simulators. There's no marketing to the Web Based Training at learningcenter.netapp.com I mentioned. These courses are mostly free of charge these days to customers and partners. In most transition cases my advice is to do in Cluster Mode as you did with your 7-Mode implementation. Create the SVM with the same provisioning as you had in 7-Mode. The disadvantage of this strategy is that you may not be taking advantage of the best provisioning practices already in your current 7-Mode environ. The questions on provisioning you had in your original post aren't quick and easy ones to answer. We take an entire module in our Oracle on NetApp course to discuss provisioning strategies. These strategies vary by size, performance, and count of how many databases need to be provisioned. I'm a big fan of NetApp Technical Reports myself. There's 541 of them I found just now in a search of the NetApp library - http://www.netapp.com/us/library/ I noted that you're using SnapCreator framework. There's some excellent information that would apply to SC as well as SnapProtect in a new TR, TR-4432 'Best Practices for SnapProtect Backup for Oracle RAC Solution'. You may also want to look at some of the performance TRs. They usualy have detailed information on the best practice configurations used to run the performance tests. Again, my apologies if you thought the previous response was marketing. I take the time to post here to be helpful not only to the original poster, but others who read these threads on the NetApp community. I hope this response has been more helpful to you.

SMLocke - You need to edit the files for the node that hosts the cluster mgt LIF. You might want to edit the config on all nodes for it to take effect on all node mgt LIFs. Also, sshd needs to be restarted to read the changes to /etc/ssh/sshd_config You probably don't need to do this, as long as you don't need to re-edit the config. It should pick up the edits you make to the motd file. I rebooted my 8.21 simulator to get it to take. I hope this response has been helpful to you. At your service, Eugene E.

SMLocke - It's a systemshell hack. You can only set the message for ssh logins to the cluster shell. You need to unlock diag user. Then 'sudo vi /etc/ssh/sshd_config'. Edit the #Banner line to uncomment it, and reference the motd file you want to use. (Your sshd_config has probably already been changed, just edit the file the Banner line is pointing to.)

NetappDow - As Yishikawa mentioned, it's a business requirements question. RDMs are a bit more work - creating the LUNs, mapping, and mounting them. VMDKs are easy to work with. RDMs may yeild better performance. A typical use case would be with high performance databases. SATA drives are often used for backups, or light IO storage. The metric I use to determine SATA v SAS provisioning is IO density, expressed as max random IOs/TB of data. ( ~300 for your SAS drives and ~50 for your 2T SATA drives ) I hope this response has been helpful to you. At your service, Eugene E.

Defrogger - There isn't a performance hit with thin provisioning. The concern would be to do it with caution not to run out of space. The performance concern with dedupe is usualy when doing the initial run on a volume. I advise to do it on off-hours, and only on one volume at a time. The tool I rcommend for performance monitoring is OnCommand Unified Manager. You may want to watch the recorded NetApp webinar I did for ITLS and FastLane Education on 'Clustered Data ONTAP Performance'. Much of it applies to 7-Mode environs as well as Cluster Mode. It can be found at: http://www.fastlaneus.com/webinars I hope this response has been helpful to you. At your service, Eugene E.

Defrogger - Your are correct that turning dedupe off wont dedupe any new data going forward. There isn't a performance hit to leave the data deduped. The dedupe fingerprint tables are used to dedupe data, not when reading deduped data. There is a performance gain for leaving the data dedeuped. Deduped blocks only have one copy cached in memory or in FlashCache. This is a big win in VM environs where there are often many copies of the same OS. All those duplicate blocks are only cached once, instead of many copies of duplicate blocks for each VM. Note that 'sis undo' is an advanced priv command in 8.2, and is not documented in the man pages. You may wish to look at NetApp TR-3958 NetApp Data Compression and Deduplication Deployment and Implementation Guide From TR-3958: "15.6 Removing Space Savings NetApp recommends contacting NetApp Customer Success Services prior to undoing deduplication or compression on a volume to determine that removing the space savings is really necessary. In many cases system performance can be restored by finding the true source of the degradation, which often can be unrelated to compression or deduplication. It is relatively easy to uncompress or undeduplicate a flexible volume and turn it back into a regular flexible volume. This can be done while the flexible volume is online, as described in this section. Undo operations can take a long time to complete. The time to complete is relative to the amount of savings and the amount of available system resources. You can view the progress of undo operations by using the sis status command. During the time when undo operations are running there may be an impact on other activity on the system. Although undo operations are low-priority background processes they do consume CPU, memory and disk resources and, as such, they should be scheduled to run during low usage times. We do not limit the number of undo operations you can run in parallel; however, the more that run, the more impact will be seen. If you determine that the impact is too great with so many in parallel or during peak times you can stop the operation using the sis stop command, which will stop the current undo. You can later restart the operation and it will continue from where it stopped. Note: Undo operations will only remove savings from the active file system, not within Snapshot copies."
