You can't make a decision on how to architect a system based solely on the

components at hand.

There are many things to consider:

is the db to be read mostly, read only, oltp?

low, medium or high transaction rates? ( you define based on HW capability )

number of users?

Criticality of performance?

For instance, RAID 5 may be entirely suitable for an application that has low
performance requirements, and you need more space than you can get from a RAID10.

enough for now.

StorEdge 3310: RAID and configuration question

Hi All,

I have a Sun v440 4 cpu 8GB ram with Sun StorEdge 3310 with 5x70 GB HDDs.

Let me give you three scenarios:

On the StorEdge 3310 Array configure RAID 1+0 Using 4 disks and use one as a local hot spare
Configure RAID 5 on the 3310 Array
Put 2 disks on the other scsi channel and configure 2 RAID-1s and use the fifth disk as global spare.

My question is, which one of the 3 choices is better and whether the third one is feasible? Moreover, if anyone has any other idea, please let me know.

In addition to the above I have another question:

In addition to the above I would like to know the pros/cons of Software mirroring?

Regards,
Naveen Nahata
