Hi Many thanks for the response. Here is some data that you asked...if u need further clarifications, pls let me know Q. I need to know how many concurrent users are there? 90 Logins on an Avg....though the database is serializabily accessable (means no two users can modify a particular table...this...

Hi David, Thanks for you reply, and to everyone else who replied. Can you please expand on your comment about SANs and why you don't recommend them. Why will RAID5 corrupt the database? Currently the database is on the SAN, is it still exposed to corruption? Thanks O'Neill3

Oniell3,you really need to get off RAID5, it is just too slow, and there is a high chance of you corrupting the database. SANs can work, (though I really don't want to recommend them), but you MUST have RAID 1 if you want any chance of speed. PS I have posted a LOT of threads on this topic, just...

We recently moved our DB from a RAID5 Array to a RAID1 Array (thanks to suggestions from others on this list) and the performance difference has been dramatically better. quote: Originally posted by oneill3 Hi All, I have a windows 200 server running navision. 2gb of memory xeon cpu raid 5 The database...

Update. I did some testing creating 250MB files on both the RAID5 & RAID1 arrays and the file create process was about 3 - 3.5 times faster on the RAID1 Array (10 seconds compared to 35 seconds). I've moved the DB to a RAID1 Array and it seems to be behaving nicely. Thanks for the help. quote...

Someone from MSFT gave me this advice, and told me to see an attached document, but none was included. Can someone translate what she's talking about? ******************* The problem is likely to be in the Navision C/AL code (codeunits 12, 80 or 90). You need to know if the standard posting process...

Most important: Never a database on RAID 5, no matter what DBMS. Start by switching to RAID 1 and You'll gain a lot performance. But first of all. Do some searching on this forum för RAID. You will have a lot to read.
