11/21/2023, 2:12 PMYes... however, I'd recommend a standard failover cluster if you don't need to spread your I/O across multiple storage locations.

11/21/2023, 2:18 PMThat's a good point to use a standard failover cluster. Do you have experience with this configuration option? When a failover is performed do FSLogix users notice this?

11/21/2023, 2:21 PMIf you use a standard failover cluster and enable continuous availability on the share you will experience no downtime at all. I do have experience with this and have used it a lot for various profile VHD containers.

11/21/2023, 6:48 PMwhat is the benefit of using a failover cluster versus FSLogix Cloud Cache?

11/21/2023, 10:48 PM@Coleman Kelly CC has been buggy for a long time. Lack of trust, higher IO compared to a failover cluster ecc.

11/21/2023, 10:48 PMthat's my personal opinion, but change my mind 🤟

11/24/2023, 5:52 PMI can answer that, CC has I/O in 3 places, on your session server/desktop and then is replayed on your cache locations. Cloud cache can only ride through a certain amount of disruption and with the I/O being distributed in this way is difficult to plan for (Think PVS write cache sizes etc...). A Failover cluster with x number of nodes and continuous availability is pretty bullet proof is spread out correctly.
Don't enable continuous availability on file shares with lots of small files. That will simply kill the file server and give poor performance. CA is meant for VHDs though.

01/26/2024, 1:11 PM@Leee Jeffries A customer asked us, if it would be possible to build their FSLogix Windows Fileserver redundant. I remembered this thread and your blog post. I'm not that good with VMware and there is one thing I don't understand: Does this work with VSAN?
In the meantime I Googled that myself, and it seems to be possible and supported: https://blogs.vmware.com/apps/2019/05/wsfc-on-vsphere.html

01/26/2024, 1:12 PM@Marco Hofmann SOFS is your way to go.

01/26/2024, 1:14 PMIf you have a single storage array, windows file cluster, standard failover. For distributed storage go with SOFS.

01/26/2024, 1:15 PM@Balint Oberrauch && @Leee Jeffries Thank you very much for the contradicting advice xD
Marco Hofmann
01/26/2024, 1:16 PMTo mark the facts: It's one VSAN cluster, with 10 nodes, and therefore one large single LUN.
So I guess you can call that a "single storage array" ?
@Balint Oberrauch I must admit, I'm not familiar with SOFS, so I can't judge if this suits my needs.

01/26/2024, 1:23 PMScale Out File Server allows you to spread a share across multiple storage locations.
Standard failover is what you want for good reliability.
