- Identify a failed RAID 5 Volume

…using Seagate’s BlackArmor Manager?
Seagate BlackArmor NAS 440 products come with a RAID 5 Volume by default to ensure data protection. If one drive fails, a user can:
- Easily identify the failed drive using the BlackArmor Manager and other tools.
- Remove the defective drive and replace it with a functioning drive provided by Seagate.
- Use BlackArmor Manager to claim the replacement drive and recover the RAID 5 volume.
All of these things can be accomplished while the BlackArmor NAS 440 is still…
A RAID 1, or "mirror", is built from two disk drives, where one disk drive is a mirror of the other (ie, the same data is stored on each disk drive). Compared to independent disk drives, a mirrored volume provides faster performance, but has only 50% of the capacity.
The following provides the steps necessary to create RAID 1 volume. It is assumes the following:
- You have backed up any/all critical data off of the BlackArmor NAS Server.
- All previous unneeded Volumes have been deleted.
- You are currently logged into the BlackArmor Manager with admin privileges.
Procedure(s):
- Mouseover Storage and click Volumes. The Volumes…
A volume with RAID 10 is built from two or more equal-sized RAID 1 volumes. Data in a volume with RAID 10 is both striped and mirrored. Mirroring provides data protection, and striping improves performance.
The following provides the steps necessary to create RAID 10 Volume. It is assumes the following:
- You have backed up any/all critical data off of the BlackArmor NAS Server.
- All previous unneeded volumes have been deleted.
- You are currently logged into the BlackArmor Manager with admin privileges.
Procedure:
- Mouseover Storage and click Volumes. The Volumes page opens.
- Click the Add icon. The Volume Add Disk Selection page opens. Select the…
A volume with RAID 5 is built from a minimum of three disk drives and uses data striping and parity data to provide redundancy. (Parity is extra information that is used to re-create data if a disk drive fails. In volumes with RAID 5, parity data is striped evenly across the disk drives with the stored data.) Parity data provides data protection, and striping improves performance.
The following provides the steps necessary to create a RAID 0/1/5/10/Spanned/JBOD volume. It is assumes the following:
- You have backed up any/all critical data off of the BlackArmor NAS Server.
- All previous unneeded volumes have…
RAID 0 is also commonly referred to as "striping". RAID 0 is known for speed. When data is written to the RAID 0 volume, it is written to all drives striped together at the same time. Think of each interface as a water hose and the volume as the bucket; the bucket will fill faster if multiple water hoses are filling it at the same time. The same holds true for striping – data writes faster to the volume because it is being written through more than one drive interface.
The downside to RAID 0 volumes is the fact that…
What do I need to consider when selecting drives for use in a RAID configuration? Can two different hard drives be used in a mirroring or RAID array, or must they be identical brands and models?
Hard drives for RAID. Mix hard drives in a RAID array?
Most SCSI RAID controllers will accept different kinds of hard drives. The hard drives should match in capacity points and rotational (RPM) speed. At best, all drives in an array will be identical–at the same firmware revision level.
RAID can be used with any size hard drive. The smallest capacity drive will determine the largest logical volume…
The following are the steps necessary to configure a RAID 1 (mirrored) volume on your OneTouch III Turbo 1TB drive:
Currently only the OneTouch III Turbo 1TB (Terabyte) drives provide RAID 1 (Mirrored) support. Configuring a RAID volume is a data destructive process. It is strongly recommended that you backup any/all data on your OneTouch III Turbo drive before proceeding.
- Double-click on the Maxtor OneTouch Manager icon on your Windows Desktop. This will launch the Onetouch Manager application. If this icon has been removed from the desktop, click Start > Programs (All Program for Windows XP) > Maxtor > OneTouch > Maxtor OneTouch™ Manager
- Click on the Settings button.…
I don’t need the redundancy of RAID five and want more usable disk space. Can I configure the NAS 4000 Series without RAID 5?
Yes, you can the NAS 4000 Series for JBOD (just a bunch of disks), spanned, spanned and mirrored, or striped disk configurations.
I don’t need the redundancy of RAID five and want more usable disk space. Can I configure the NAS 4000 Series without RAID 5?
Yes, you can the NAS 4000 Series for JBOD (just a bunch of disks), spanned, spanned and mirrored, or striped disk configurations.
The Maxtor Onetouch III Turbo drive will be released as a 600 gigabyte (GB) RAID 0 model, and a 1 terabyte (1 TB, 1000 GB) RAID 0/1 model.
RAID 1 can now be used with the OneTouch III Turbo 600 GB models with updated installation software.
