Fusion-io cards as an NFS IO cache ?
While tackling OS integration, what would really be welcome would be a cacheFS integration, so that NFS mounts to Linux or VMware hosts could hide most of the network latency through a 620 Gb cache.
This would be a huge application performance and network traffic win, while being totally transparent to applications.
(right now our applications cache hot data manually to the Fusion-IO cards. not transparent!)
