Our aging squid proxy is due for replacement, and I am looking to maximize performance and stability on the new box. The current platform is this: Dual P3/733, Mandrake 9.2 768Mb RAM 4x 9Gb 10k rpm scsi drives on adaptec 3940, 1 for O/S, 3 for cache. The above has served well for a few years, handling a consistent load of ~500 users, and about 350-450Gb/month of data. (with delay pools on most users). Long-term MRTG graphing of load shows the system is not CPU bound, with a steady avg CPU load of about 20%, avg http & dns times of 75ms, and typical peak requests/sec of ~60 each day. Our standard server is a Dell 2850 with 4 or more 15K drives and RAID5. Obviously RAID5 isn't needed for the cache, so I'm wondering what is the best disk option for cache performance in a machine like this, which offers up to 6 drives in a scsi backplane. Any tips appreciated. Thanks. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, I.T. Manager Shawnigan Lake School http://www.sls.bc.ca swright@xxxxxxxxx
