[Simh] Best NFS Serevr for OpenVMS?

[Larry Baker]

Zane,

I don't think there are file size limitations.  The server file  
system (Linux ext3) is no problem.  I just looked at the file sizes  
of the compressed Backup save sets.  I see several almost 5 GB, which  
means they were probably 8–10 GB when Backup wrote them.  I still use  
it to make backups from our OpenVMS/Alpha system.  I don't know what  
limitations the SIMH VAX might have on disk size.  I remember running  
into the 24-bit hardware size limitation on no. of disk blocks on a  
real MicroVAX III.  (Disks appear to be module 8 GB their capacity; a  
20 GB drive shows up as 4 GB.)  This was using a SCSI II controller  
that emulated an MSCP QDA50 controller.
