Fasal,
To expand on Mike's comments, SFW (Storage Foundation for Windows) does not contain a Veritas File System component and therefore we use NTFS. Natively NTFS is not a cluster file system and as such only one host at a time can have Read/Write Access to a particular volume/partition.
We have however recently introduced certain technologies (Multi-Node Disk Group Access) that we eventually result in the ability for a disk group to be simultaneously imported on more than 1 host as R/W. The net of this feature is that individual volumes will therefore also be accessible by multiple hosts (but not concurrently) as it will still have the NTFS limitation.
CSV in Windows 2008 and Windows 2012 do offer the appearance of Cluster File System, but not in the same sense as SFCFS. CSV's support only basic disks, whereas SFW volumes are Dynamic.
