in most cases the hardware raid controller is not worth the money, as a software raid usually gives a much better performance with less latency and more control for the operating system ... nevertheless, hw-raid can have some advantages if it is done properly, e.g. auto reconstruction without affecting the system performance and/or battery buffering in power failure cases ... best, Herbert > > http://www.tyan.com/archive/products/html/gx28b2882_spec.html > > > > looking at the specs for the GX28 I see AMD chipsets > > which 'might' lack proper support, the Sil 3114 there > > is also connected to the legacy 32bit bus and does > > only support SATA 1.0, so I wouldn#t expect too much > > from that ... > > > > HTH, > > Herbert > > > > > -- > > > > > > Chuck > > > > > > _______________________________________________ > > > Vserver mailing list > > > [email protected] > > > http://list.linux-vserver.org/mailman/listinfo/vserver > > > > -- > > Chuck > > "...and the hordes of M$*ft users descended upon me in their anger, > and asked 'Why do you not get the viruses or the BlueScreensOfDeath > or insecure system troubles and slowness or pay through the nose > for an OS as *we* do?!!', and I answered...'I use Linux'.
