Am re-purposing an older 3U HP server, and am wondering what impact hard drive performance has on overall UTM performance. The server supports up to 6 drives, in various hardware RAID configurations. However, six 10k-15k rpm drives add a lot of noise and power consumption. Would scaling down to just a pair of 10k rpm drives in mirror mode really affect performance? Using Firewall, IPS, Web Filtering, POP3 Proxy, Antivirus/Antispam/Antispyware. 5-10 workstations, frequent simultaneous streaming media (netflix, hulu, etc.), gaming (like steam), downloading, etc. Server has two dual-core Xeon 2.8GHz, currently only 2GB RAM (hope to add more), with six 72GB 10k-15k Ultra SCSI 3 drives in RAID 5. Or is this total overkill (other than the meager RAM)? This will replace the current Astaro 8 running on a Pentium 4 desktop PC with 2GB RAM, which is peaking 100% CPU usage & memory usage averaging 65%. Internet is currently 10mb cable, may upgrade in future.
Before I got the server, my plan was to use 3 older desktop PC's (Athlon XP 2000+) in Cluster.
Thanks for any advice!
