<div dir="ltr" >CES is more than just an export service for SMB, obviously it also supports NFS and Object as export protocols, and more specifically it allows us to move items like NFS away from a kernel service and up to a user service which makes the system more secure.</div>
<div dir="ltr" > </div>
<div dir="ltr" >We also use the CES nodes as the transport mechanism for Transparent Cloud Tiering (TCT) for export out to an external cloud service.</div>
<div dir="ltr" > </div>
<div dir="ltr" >We are heavily reliant on what the SAMBA stack supports, and to be honest the limitations in your scenario are actually limitation of the SMB stack rather than of Spectrum Scale specifically (its why we have the native posix client).</div>
<div dir="ltr" > </div>
<div dir="ltr" >The CES platform is designed to cater for workloads and scenarios beyond the HPC space, it gives "legacy" support for protocols which really are not the most efficient way to transfer data, but are heavily used by the broader file sharing community today. </div>
<div dir="ltr" > </div>
<div dir="ltr" >In my opinion CES is a must have item to be involved in any "corporate" file system discussion, is it the nirvana answer... of course not, but there is on going work to develop and expand the functionality and support structures around CES, does it scale as far as we would like.. not yet but hopefully in conjunction with the SAMBA team we will get there eventually.</div>
<div dir="ltr" > </div>
<div dir="ltr" >All too often we seem to forget about the native posix client and try and make SMB or NFS "fit" the scope of the functionality we are trying to achieve, sometimes its because its what other vendors are doing, sometimes because we actually want to access the same data by multiple protocols, all too often its because we have to tick a check box in a response document somewhere.</div>
