The server spec:
ML570G1 with smart array 5312 controller
4x 36GB HDD (RAID 5)
C drive: 2 X 36Gb SCSI Hdd (Raid 1)contains Windows 2003 server R2
D drive: 3 X 36Gb SCSI Hdd (Raid 5)contains database and contents
Currently the D drive is running out of space. Thus i have purchased 2 units of 146Gb Hdd to increase the disk space. As far as i know there are 2 ways, one is to create Raid 1 for the 2 new Hdd and create logical drive E or add them to the Raid 5 array for D drive. Could u guys please advise on this and suggest the best solution (or other alternate solution), as well as provide me the pros and cons of my 2 solutions..
Next, how do I add additional 2 units of 146Gb HDD into the RAID 5 array and combine it with the unused space in D drive? Is it also possible to add different size of disk into an array? Can provide me step by step?
Thank you in advance guys!!

Re: How do i add additional Hdd into an existing array?
Making a RAID 1 with the two 146 GB disks gives you a 146 Gb new drive (E:).
Both operations can be done online, using the Array Configuration Utility.

Re: How do i add additional Hdd into an existing array?
I won't add them to the RAID 5 as will be a waste of space.
I won't mix a RAID 5 and RAID 5 as will be a waste of performance.
So, considering what you DO have, is probably best:
Create a RAID 1. Move your Database files to this Unit, for performance and availability reasons.
Use the old RAID 5 for less critical data and database archiving.
