I am looking at the feasibility of replacing our Netware 6.5 (not on SLES) FILE SERVER with a Linux only solution. Netware has been our server of choice because of it's ability to handle so many connections and I/Os at the same time. Our disk I/O on this hardware and software is NEVER swamped out by the LAN I/O for more than a few seconds at a time.
We have over 500 automated XP/Win7 computers reading and writing both large and small files to the NW server ALL THE TIME. - Speed is the most important parameter.
Assuming we put Linux on the SAME HARDWARE as the Netware server (Quad Core Xeon, 32G RAM, PERC SAS Controller with external SAS RAID5 array, 5 Gigabit ethernet cards)--- What configuration will provide the same or better performance to the NW server?
Share : NFS vs SAMBA vs Something Else?
File System : BTRFS, EXT4, GFS, GFS2, XFS?
Any assistance is appreciated.
