Resize RAID 1 Mirror Partition with Partition Magic Server Software

Scenario: I have a Dell PowerEdge 2650 Server running Windows Server 2003. The two SATA hard drives are setup in a hardware RAID 1 configuration and are partitioned as two partitions - C: drive is 12GB and Partition D: is 60GB. This is how it came from Dell. I am quickly running out of disk space on the C: drive and would like to extend the RAID 1 system partition.

How to resize RAID 1 partition when C drive is full? The traditional solution: you need to backup files, delete partitions, rebuild Hardware RAID 1 array and restore data back to new RAID 1 array. It is risky and time-consuming! Is there any way to resize RAID 1 system partition easily and safely? Of course, as Partition Magic Server Software, Partition Assistant Server Edition is a powerful and reliable RAID partition manager that helps you optimize Server performance and maximize disk space usage.

Overview of Hardware RAID 1 Mirror

RAID 1, implemented as disk mirroring for data redundancy, has its data duplicated on two drives; namely, if either drive fails, you can simply replace mirrored drive and rebuild RAID 1 array without data loss. Therefore, it is popular for those who require fault tolerance.

Drive Requirements: Exactly two hard disks. Any type is available but both should ideally be identical.

Space Efficiency: 50% if both drives are equal size.

Advantages: Very high data protection and good performance.

Disadvantages: Relatively high cost due to redundant drives; lowest storage efficiency of the single RAID levels.

In fact, after you create a RAID 1 array, the two physical disks are detected by Windows Disk Management as a single virtual disk:

As the above screenshot shown, the RAID 1 array is recognized as Disk 0 by host system. Now we can easily and safely shrink D partition to generate unallocated space and extend system RAID 1 partition with Partition Assistant Sever Edition, which works well all the Hardware RAID levels, such as RAID 0, 1, 5, 10 and supports all types of RAID Controllers, including IDE RAID Controllers, SCSI, SAS, S-ATA RAID Controllers, serial ATA host Controllers and devices.

Apart from RAID partition resizing feature, Partition Assistant Server Edition also helps you merge adjacent partitions into a bigger one, allocate free space from one partition to another, extend NTFS system partition without rebooting, split partition into two or more, sector by sector clone hard drive to upgrade disk without reinstalling Windows and applications, clone partition to another disk for migrating system volume and backup important data, etc. You can free download demo version to test before you buy full version.

Tips: For Enterprise users, Unlimited Edition provides unlimited usage within one company to save money, namely, you can install it on multiple machines in your company to maximize business productivity whilst minimizing the total cost of management.
