Greetings, Having rolled out GFS, lustre, gluster and found each of them lacking (in one way or another), I'm wondering whether anyone could give me an assessment of whether PVFS could be appropriate in a business environment which, I suspect, is much different where it is typically deployed.
My company does image processing and we presently have ~700TB of image data on about 25 nexsan satabeast disk storage arrays. The data is presented to a large number of windows clients via about 8-10 windows file servers. Because of the large quantity of data we only backup the most critical data (perhaps 10TB). We rely on the nexsans, RAID 6, and very close monitoring of disk health to ensure that we don't corrupt or lose data. With only one exception we have not yet, in 4 or 5 years, lost data (and that was human error). We are less concerned about data availability. If a file server goes down we can wait several hours for it to become available again. What we can't withstand is DATA LOSS. Our client's typical workflow is: copy 500Meg of data files from file server(s) to local disk compute copy output files back to file server(s) Our file servers have 4 gig nics which are aggregated; our clients all have single gig-e. We would be happy if PVFS was able to keep 4 simultaneous clients read files at 100MB/sec each. So, does anyone know anyone who trusts PVFS for this type of use? Also, does anyone provide commercial support for PVFS? Thanks much, JR _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
