Subject Re: Using S3/Minio as the only secondary storage
Date Wed, 17 Jul 2019 13:30:18 GMT
Thanks Will,

I remember having the discussion with Pierre-Luc on his use of Swift for
templates.  I was curious about the differences on S3 vs Swift for SS since
looking at the CS UI when it comes to setting up an S3 image store... the
NFS staging is optional.  And this make sense to me if your object storage
is fast and accessible locally,  why the need for staging/caching.    The
documentation could mention if it is possible to use S3 secondary and
nothing else,  starting with if SSVM templates can be uploaded to a
bucket.    I will certainly ask Syed later today :)
