| - | There are a few CephFS file systems available in the sepia lab. These reside on the [[services:longrunningcluster|Long Running Cluster]]. Access to this Ceph cluster is available for any machine on the [[:vpnaccess|sepia VPN]]. You can and **should** mount these file systems on your laptop or development machine. This reduces load on some shared machines, like [[services:teuthology|teuthology]], and usually provides faster access depending on your client or network. | + | There are a few CephFS file systems available in the sepia lab.

This reduces load on some shared machines, like [[services:teuthology|teuthology]], and usually provides faster access depending on your client or network. However, for everyday use, you may prefer to access CephFS from a machine co-located with the other lab infrastructure, such as a [[:devplayground|Developer Playground]] machine, where OSD latency/bandwidth will be optimal. | ||
