dkorns - A long post to ask a short question ! There's nothing about MetroCluster I know of that would restrict you from setting up SnapMirror or Snap vault to a remote destination. We teach it as reference architecture in our C-Mode Data Protection class. Reason to do it is to protect data beyond the 300km limit of MC. There's one gotcha I can think of for implementing your WFA workflows. They might want to put in logic to ensure the DP destination is NOT the MetroCluster partner cluster. No changes I know of in 9.X that would affect these workflows. Would love to come teach our new 'Creating Custom Workflows with WFA' for your customer, if we haven't done so already! 🙂 I hope this response has been helpful to you. At your service, Eugene E.

Mjaber - I was hanging out here on the NetApp Community and wasn't finding any good questions to answer, so started to browse through my old posts. This one stood out for me due to the Kudos I got on my short answer. The short answer I had orriginaly posted was one I had been given on a recent NetApp interview from a client. Thought it was worth some time to make a follow up response to your question and try to bring the thread back to life. I'll start with some general NetApp questions and then probably make some follow up posts with more advanced topics. My plan is to write questions on various topics like 7-Mode, Cluster Mode, DR, history, simulators, OCI, APIs, WFA, networking, etc. over time. Please understand that I teach NetApp currently for a living as well as consult for clients. This is the reason I hang out on the Community web site. It's my job to answer ANY question a student may ask in class. I have a passion for NetApp that drives these questions I'm asking and have the answers for. I hope that readers will take this up as a fun challenge ? Respond to this post, or create a new thread with any one of these 'interview' questions. I'll be happy to write posts with the answers ! Many of these questions already have answers written here on the Community web site ... 🙂 General Questions: Who is Dave Hitz ? Tom Mendoza ? James Lau ? Tom Georgens ? Dan Warmenhoven ? Brian Pawlowski ? What is a NetApp ? What does ONTAP stand for ? When was NetApp founded ? What's the first NetApp model # you used ? What's the latest NetApp model # you used ? What is an aggregate ? What you should you consider when creating an aggregate ? What is NVRAM ? What is a Consistancy Point ? What is WAFL ? What is an inode ? What is an xinode ? What is the default inode allocation for a volume ? What is a Snapshot Copy ? Why is a Snapshot not a Copy ? What are the the ways to use an aggregate snapshot ? What is SnapRestore ? What are the ways SnapRestore Can be used ? I hope this response has been helpful to you. At your service, Eugene E.

Ryan - There is no metric for estimated IOs on an aggr, but you can compute it. See my reply to IOs on a volume: http://community.netapp.com/t5/FAS-and-V-Series-Storage-Systems-Discussions/Estimate-IOPs-Capacity/m-p/125924#M7786 Given that disk drive utilization on the aggr may be the key metric to monitor.

Cloud Miner - No, but it can be calculated on an aggregate basis. IOs on the aggr are shared by all vols on the aggr. IOs Per Disk X # of Data Drives in the aggr. Random IOs per disk type at 50% utilization: SATA 75 FC/SAS 10K RPM 140 " 15K RPM 175 20 SAS @ 15k RPM = 3500 IOs on the aggr. I hope this response has been helpful to you. At your service, Eugene E.

CloudMiner - Another question without a short answer. You're probably referring to recreation rather than reconstruction. (reconstruction would be on a corrupted aggregate and is painful.) When you know the aggregate geometry is out of guidelines, or when the disk utilization exceeds 50%. Rather than recreate the aggregate you could add disk to it and optionaly run the 'reallocate' command on volumes in it and the aggregate. That's the short answer... 🙂 I hope this response has been helpful to you. At your service, Eugene E.

CloudMiner - That's not a short answer subject. Minimum for RAID-DP is 5 disks, for RAID4 it's 3. That wouldn't give you very good disk utilization. Max disk #s depend on the controller platform. Default RAID group sizes for DP are 14 and 16 for SATA and SAS/FC disks. In general you want to build your aggrs with equal sized RAID groups and not stray too far from the default RAID group sizes... I hope this response has been helpful to you.
