EMC also announced its Multi-Path File System for iSCSI (MPFSi), which is file-sharing software that boosts the performance of NAS networks by up to four times over earlier system capabilities. MPFSi works by allowing NAS user requests to come in over a standard file systems protocol (CIFS or NFS), but the data is then served to the host using the Internet SCSI protocol.
The MPFSi software also allows data to be replicated between NAS arrays using the iSCSI protocol.
Internet SCSI is a block-based protocol that allows for far greater data transfer rates.
“This allows large objects [files] for things like grid computing or software development to be served up much faster,” Steinhardt said.
EMC MPFSi is priced according to the number of servers in the environment. In a maximum configuration, MPFSi lists for $225 per server. EMC Celerra Replicator for iSCSI has a list price of $18,600 per frame. It and the other functionality announced today will be generally available in early March.
