Hi Prashant! Welcome to DynamicsUsers.net [quote]The last set contains the Transaction Log and the Tempdb.[/quote] Oh, oh ... this is a big mistake! The Transaction Log of the NAV database MUST be stored exclusively on a dedicated physical drive - means nothng else is stored there! And especially not...

Hi, This is regarding to the same setup as Mitesh has mentioned and put up in my place, as I maintain the operations out here. We have changed the scenario a bit. Firstly what i found out was Navision doesnt work with SATA disks which is true as I was the one along with Mitesh doing the test on the same...

Here's an update on RAID-levels: In the HW Sizing guide for NAV 5.0 Microsoft has changed their recommendation from RAID0+1 to RAID10. Surely it's because RAID10 offers higher redundancy than 0+1. A difference to consider between the two RAID levels performance when the system has lost one or...

Yes. Navision (both Native and SQL) should fly on RAID4 since it's nothing less then RAID0 with a dedicated disk for parity (maybe that makes it even faster than RAID0, i don't know). But You don't have any redundancy in RAID4. So I suggest we just forget about that RAID-level :-) //Lars

[quote user="lars westman"]...I hope that made sense. Nested RAID isn't allways easy to understand.[/quote] Well technically RAID really only covers 1,2,3,4 and 5. All the rest are mde up anyway. So i think we can all be forgiven for not being able to makes sense out of the rest, since...

Now this seems difficult :-) You can think of 1+0 as an ordinary RAID1 but you mirror the whole RAID1 set with a striped RAID0-set. 0+1 is then an ordinary RAID0 but you double it so you have two mirrored RAID0's. 0+1 is faster, but since it is two RAID0-stripes mirrored you can't lose disks...

[quote user="DenSter"] 0+1: striping mirrored sets 1+0: mirroring striped arrays The way it was explained to me: 0+1 is faster as well as more fault tolerant. You can theoretically lose one disk in each mirrored set and still run, losing one disk only affects the disk itself, since there is...

[quote user="lars westman"] It's You own choice to run RAID 10/1+0 or 0+1. Microsoft suggests 0+1 in their sizing guide. RAID 10 is more fault tolerant but RAID 0+1 is faster. The key difference from RAID 1+0 is that RAID 0+1 creates a second striped set to mirror a primary striped set...
