So I am trying understand the caching policy settings. I found them here: https://docs.netapp.com/us-en/active-iq-unified-manager-99/online-help/reference-volume-health-fields.html There are lines that I do not understand, for example: "This policy is a combination of the Meta and No Read-Random Write and does the following: Read caches only"... but Meta caches only metadata and no-read-random write does not cache writes for reads? Or perhaps I am misunderstanding, "Write cache random overwritten user data", I write caching to tier 1 of random data written. It is like one of those puzzles in the back of the newspaper so I tried to put it into a spreadsheet so it is quicker to understand than the documentation. IDK if I have understood I correctly, but I think it would be easier to understand than the long list that looks like it has been reverse engineered from the software. 😄 Are there anyone who can look at the spreadsheet.png and see if I have understood it correctly? 😄

Hi, I'm set up my first AFF NetApp for hosting KVM Virtual machine, shared via NFS volume. Until now I have always used FAS with NFS for hosting many small files. I know FlexGroup but I read that it works better with many small files. My setup is an AFF-A250 (ontap 9.11.1) with 16 x 1,96TB SSD, that provides 2 aggregates of approximately 10TB. Volumes will be shared via NFS to 8 Linux KVM hosts. VM disks files are relatively small, around 50GB and only someone brow up to 500GB. Do you suggest creating two FlexVol about 10TB, one per node, or creating only one FlexGroup that can grow up to 20 TB? Thanks

We are running ONTAP version 9.9.1P7. We have been using Sophos, but that product is EOL. We are trying to decide among the remaining vendors- McAfee, Trend Micro, and Symantec. Has anyone had good/bad experiences with any of these? Does anyone have a recommendation for best option?

Hi all. I'm just curious if anyone has built a spreadsheet (or other method) to create all the commands (vol create, lun create, lun map) (using concatenate or similar) that would create volumes, luns and igs at the CLI? Then I would copy the commands out of the spreadsheet and paste them into the CLI. I have to add 40 individual LUNs to 40 different servers. I would like to paste these server names into a column in Excel along with the IG group names and have it put together the CLI commands. If someone has a more efficient way to do this, please share if you don't mind. Its only 40 LUNs this time, but we have a project coming up which will require me to do this for many more production servers. Thanks for the help! Carl
