Great video! Looking forward to the storage design video.. Thank you!

[chrisipad]

thanks for this easy to follow comparison between NFS VS iSCSI!

[ewenchan]

Thank you for this video.

Yes, I would definitely love to learn more about the different use cases for iSCSI vs. NFS.

I've never really dove into much, so thank you for putting this video together and explaining this to us.

I greatly appreciate it.

I think a deeper dive into the philosophy of storage design would be helpful! I've setup ISCSI, Fiber Channel, and SMB/NFS shares in the past and through various VMware topologies but never really got into the nitty gritty of optimizing storage for your VMs for performance, security, and scalability :)

[joelsmith]

The case you mention near the end of the video with a Graylog VM, and how to handle the storage differently would be super helpful to me! I'm planning on setting up Graylog (sort of half started already) and the storage aspect is one part I was very unsure about.

[engrpiman]

Side note: I have found that Synology always reattaches via ISCSI when the VM reboots. My Qnap NASs often had trouble and needed me to manually mount the drive.

What you do is uses block storage and then use Veeam to snapshot and backup the individual VMs. Works great.

Great video, I'm in the market to build a network storage solution and this was very much in my interest. I have the requirement for family storage but I also host VM's as well that will be utilizing the storage

[Actionjack]

Would be very interested in different use cases of running a Windows VM with ISCi and how the data should interface with the VM. Looking forward to that and more. Thanks

Interesting content. This was always a hot topic when implementing either EMC or NetApp systems with VM Ware and/or Windows running on bare metal in a clustered environment. I'm sure a lot has changed since I touched those, but at the time tiered storage was handled differently at a block vs file level.

hmm . . . I have thin provisioned iSCSI before. Just this week in fact.
Excellent video, sir 👍

[tedmiles]

24:20 If you think you'll need to use snapshots on truenas/zfs. Why not make multiple zvols ...one per vm, instead of one zvol for a pool of VMs?

[mscari]

How about using VMM Pro as an hypervisor? Would the performance be better compared to the setup you tested?

[Mr_Sprint]

As mentioned about TrueNAS and restoring snapshots, this is why I set up separate extends for each VM, so no two VMs live on the same LUN.

What was your disk layout on the TrueNAS system? I am trying to run the same suite, and I am getting 300seconds on the SQLite tests.

[RyanOHaganWA]

Hey Tom, can we do a segment about CEPH?

[andibiront]

Running TrueNAS Core and ESXi. Both, the NAS and the ESXi are using thin provisioning with iSCSI. The ESXi even sends UNMAP commands to TrueNAS when a thin disk shrinks (files are deleted on the GuestOS FileSystem).

[hazaqames]

Did you use NFS 4.1 and multipathing? I may have missed your NFS setup.

[phrag]

super good explaination, I've used the "ethernet to HDD" analogy before to describe iSCSI. or a "locally appearing, network attached raw block of a drive that looks like a locally installed drive to the layman."

Ethernet to HDD is better I guess.

[adam]

In spite of some performance degradation, NFS all the way for me. I find the convenience and flexibility are worth a lot more than the performance gains (in some cases) of iSCSI. Thanks for the video.
