Hi I will need a fast data crunching workstation (or two of them) and after my initial experience with FreeBSD I will be sticking with it (and telling othe people about it). The intention of this email is to receive some feedback as regards to the tradeoffs of some hardware components. The workstation is targeted primary for storing and analysing large amounts of network traffic measurements. This translates to a high performance (PIII Xeon or 2 PIII@500Mhz), high data transfer from/to large disk (>30 GB). The system is not intended to be used by a large number of simultaneous users. Here are my questions Q1: Given that I need fast processing for few users (max 3-4), would a PIII Xeon@500Mhz be preferable (cost/performance) compared to a 2 PIII@ 500 Mhz ? Of course this is related to how faster a Xeon processor is, but is also related to how well FreeBSD can take advantage of a multiprocessor system. Q2: How much better sould I expect a SCSI drive to perform compared to an EIDE (note that this question refers to the particular application environment). (Although, due to budget constraints I might end up getting one SCSI-based and one-EIDE based) Q3: Though I will get a tape backup, I might be considering some other form of backup/ fault tolerant system. What are the options/tradeoffs (RAID, mirror of hard disk, etc), and what do other people consider an good solution for the particular application environment. Thanks for time & keep up the good work on FreeBSD !!! -- Vasilios A.
