[Freeswitch-users] Seeking opinion on shared disk space

Hi, In my deployment scenario, I plan to have two redundant freeswitch servers running on two different boxes. Two key features I am leveraging on freeswitch are voicemail and call recording and playback., and as a result of that, a shared storage for playback of the recorded wav files is needed. When the user traffic is high, I am affraid that NFS or even GFS can't scale well. On the other hand, a real SAN hardware with optical-fabric is too expensive for us. We are therefore considering using iSCSI SAN to build a cheap SAN for that purpose. Does anyone have experience setting up a shared storage between multiple freeswitch servers and can share some inputs with me? Thanks for all your help. Woody
