There's no way that the PostgreSQL team can do a better job in our spare time. i consider this a fair answer, but i have a slightly different question to ask, inspired by my discussions with a good friend who is a top notch Informix DBA. there are advantages to being able to split the database across a slew of disk drives. if we accept the notion of using the native OS filesystem on each, it would seem that being able to direct various tables and indices to specific drives might be a valuble capability. i know that i could go into /var/lib/pgsql/data/base and fan the contents out, but this is unweildy and impractical. has any consideration been given to providing a way to manage such a deployment? or is it the judgement of the hackers community that a monsterous raid-10 array offers comparable performance? i forget how large the data store on my friend's current project is, but i'll check. knowing the size and transaction rate he's dealing with might put a finer point on this discussion. richard -- Richard Welty [EMAIL PROTECTED] Averill Park Networking 518-573-7592 Java, PHP, PostgreSQL, Unix, Linux, IP Network Engineering, Security ---(end of broadcast)--- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]

Re: [PERFORM] Adaptec/LSI/?? RAID

For Linux and FreeBSD, I'd be less worried as open source development of drivers usually lead to better testing bug-fixing. Adaptec is in the doghouse in some corners of the community because they have behaved badly about releasing documentation on some of their current RAID controllers to *BSD developers. FreeBSD has a not-quite-free driver for those latest Adaptecs. OpenBSD wants nothing to do with them. richard -- Richard Welty [EMAIL PROTECTED] Averill Park Networking Java, PHP, PostgreSQL, Unix, Linux, IP Network Engineering, Security Well, if you're not going to expect unexpected flames, what's the point of going anywhere? -- Truckle the Uncivil ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
