Panache: A Parallel Filesystem Cache For Global File Access
the GPFS filesystem. The work they reckon hither is how to enable a site to access a remote site's servers transparently without suffering from the effects of WAN latencies. The respond is easy: role a cache filesystem/cluster at the remote site. But at that topographic point are a lot of issues to resolve for this to operate seamlessly.
Panache is a parallel filesystem cache to render reliability consistency together with performance of a cluster filesystem despite the physical distance. Panache supports asynchronous operations for writes for both information together with metadata updates. Panache uses synchronous operations for reads: if the read misses the panache cache cluster or the validity timer of the information inwards the cache had expired, the functioning waits till the information is read from the remote cluster filesystem.
Panache architecture
xFS provides distributed collaborative caching and would last suitable for this task, I think.
Panache uses a complicated distributed lock machinery at the gateways of the remote site to classify the dependability of update operations originating at multiple gateways. Wouldn't it last easier to instead force these updates on a best-effort dry reason to the remote cluster/filesystem together with allow it classify out these dependabilities? Why was this non considered equally an option?
