Hi Everyone, We started testing the idea of using Ceph storage with VMware, the idea was to provide Ceph storage through open stack to VMware, by creating a virtual machine coming from Ceph + Openstack , which acts as an NFS gateway, then mount that storage on top of VMware cluster.
When mounting the NFS exports using the sync option, we noticed a huge degradation in performance which makes it very slow to use it in production, the async option makes it much better but then there is the risk of it being risky that in case a failure shall happen, some data might be lost in that Scenario. Now I understand that some people in the ceph community are using Ceph with VMware using NFS gateways, so if you can kindly shed some light on your experience, and if you do use it in production purpose, that would be great and how did you mitigate the sync/async options and keep write performance. Thanks you!!! Regards, Ossi
