Mandatory SFA Block Driver Update For Embedded File Systems ( 08/17 )
Technical Support Bulletin, SPT-TSB-0082 (A2). SFA OS™ Mandatory Update to SFA Block Driver for Embedded File Systems.
Issue Summary
File system software running on SFA storage platforms with embedded processing support require an SFA block driver on each virtual machine (VM) in order to access local SFA storage. This block driver is not part of SFA OS, but is shipped with DDN file system solutions such as GRIDScaler and EXAScaler. Custom solutions engineered by DDN Professional Services for other file systems, such as XFS or EXT4, will also use the SFA block driver if the file system executes on the storage VMs.
