lc2000 Vs tc4100 - Raid Configurations

[nick kernick]

Over the past few years we have installed Lc2000 Netservers with 3 disk RAID5. The installation using default settings on the Netraid 1M Card.

We recently were forced to install tc4100 servers and now the performance on the servers for RAID 5 is terrible. Has anybody suffered similar problems.

The disk write on 500MB was 3mins, as opposed to 40seconds on RAID0. Does this make sense?

First off, yes it does make sense that a RAID 5 is slower than a RAID 0. There is no data parity calculations involved in a RAID 0. Is it suppose to be that much slower, I don't know. Are you running the latest drivers and firmware on the controller? You can find those here:

Also, make sure the controller is in PCI slot 5.
