Hello, I am building a 6x500GB SATA HARDWARE RAID5 storage server to - Store large files, 10BM~1GB/file - Handling 500+ concurrent connections - Transfer rate around 100~200Mbit/s
I am thinking of using the patch from Wojciech Puchar to reduce hard drive data seek in order to handle large number of concurrent connections whilst outputting 100~200Mbit/s. patch /usr/src/sys/sys/param.h #ifndef DFLTPHYS #define DFLTPHYS (1024 * 1024) /* default max raw I/O transfer size */ #endif #ifndef MAXPHYS #define MAXPHYS (1024 * 1024) /* max raw I/O transfer size */ #endif #ifndef MAXDUMPPGS To store files greater than 10MB, I come up with the following proposal for my File System: - UFS2 - Soft Update Enable - block-size 1,048,576 I am not completely sure what advantage I got from this configuration but I am pretty sure that FSCK is much quicker with 1M file system block-size. Is there any other thing I need to consider in term of performance and reliability? I hope that this system will perform much better than my current 6x300GB SCSI 10K RPM system. Appreciate any advice, Danny _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
