Hi

What is recommended RAID in BaaN 4c4.

Hardware Sun Soarlis under three tier architecture..

Thanks and Advance

Either RAID 1 or RAID 10 (0+1). Definatively NOT RAID-5 whatever SSA tells you!!!!

Need justification for why it shouldn't be RAID 5?

¿Hardware Sun Solaris under three tier architecture..? I don't see clearly what do yo mean...

If you have a Baan application server and an Oracle server, please give an structure RAID1 & RAID0+1 to the DB, if you want to save some disks, put Baan on RAID5 (it´s slower for the write operations, but this is not a problem for the baan soft.)

For the database I fully agree. I also want to say that diskspace is not important, spindles are. And of course sufficient controllers if you have many disks.

For Baan I partly agree. Baan also writes some things to the $BSE/tmp directory and for some sessions these files can become large. The faster the IO, the better. But I think that RAID 5 for the application will work for 90% of the Baan users.

Kind regards,

I think it would work fine - except it's really sort of overkill..

Do you really need ultimate redundancy for your $BSE?

Thanks to all for suggetions.

RAID Level Uses

Level 0 (striping)
Any application which requires very high speed storage, but does not need redundancy. Photoshop temporary files are a good example.

Level 1 (mirroring)
Applications which require redundancy with fast random writes; entry-level systems where only two drives are available. Small file servers are an example.

Level 0/1 or 10 (mirroring and striping)
Dual level raid, combines multiple mirrored drives (RAID 1) with data striping (RAID 0) into a single array. Provides highest performance with data protection.

Level 5 (distributed parity)
Similar to level 4, but may provide higher performance if most I/O is random and in small chunks. Database servers are an example.
Level 0/5 or 50
Dual level raid, combines multiple RAID 5 sets with data striping (RAID 0). Increased reliability and performance over standard RAID5 that can stand a multiple drive failure; one hard drive per RAID5 set.
