Objectives
The Volume Management in NSS300 series shows the model, size, and current status of the disks in the NAS. The Volume Management utility helps users format volumes, check disks, and scan bad blocks on the disk.
Applicable Devices
• NSS 322
• NSS 324
• NSS 326
Create Volume Type
1. At the configuration utility, choose Disk Management > Volume Management.
2. Click on a desired volume type that is supported by NAS.
• Single Disk Volume - Each disk will be used as a standalone disk. However, if a disk is damaged, all data will be lost.
• RAID 1 Mirroring Disk Volume — RAID 1 (mirroring disk) protects data by automatically backing up the contents of one drive onto the second drive of a mirrored pair. This protects data if one of the drives fails.
• RAID 0 Striping Disk Volume — RAID 0 (striping disk) combines 2 or more drives into one larger disk. It offers the fastest disk access but it does not have any protection of data if the striped array fails.
• RAID 10 Disk Volume — RAID 10 combines the advantages of RAID 0 and RAID 1 in a single system. It provides security by mirroring all data on a secondary set of disks while using striping across each set of disks to speed up data transfers.
• Linear Disk Volume (JBOD) — JBOD is also defined as “Just a Bunch of Disks.” It combines two or more disks into one larger disk. When a file is saved, it will be saved on physical disks sequentially, but does not have a disk failure file protection function.
• RAID 5 Disk Volume — RAID 5 disk volume is ideal for organizations running databases and other transaction-based applications that require storage efficiency and data protection. To create a RAID 5 disk volume, a minimum of 3 hard disks are required.
• RAID 6 Disk Volume — RAID 6 disk volume is ideal for important data protection. To create a RAID 6 disk volume, a minimum of 4 hard disks are required. The total capacity of RAID 6 disk volume equals the size of the smallest capacity disk in the array x (number of hard disks -2).
• RAID 5, RAID 6 Read-only Mode — The drive configuration enters read-only mode in the following occasions:
• 2 drives are damaged in RAID 5
• 3 drives are damaged in RAID 6
• The drives in the above configurations are read-only. It is recommended to re-create new drive configuration in such case.
3. Choose parameters for your selected volume type.
4. Click Create.
Scan Bad Blocks on Disk
1. Choose Disk Management > Volume Management.
2. Click Scan Now. The status of the scan is shown in the Status column.
Format a Volume
1. Choose Disk Management > Volume Management.
2. Click Format Now. Formatting a volume will remove all data from it.
3. Choose a file system type and click OK.
When the disk is formatted, the NAS will create the following default share folders:
• Public - Network share for file sharing.
• Download - Network share for Download Station.
• Multimedia - Network share for Multimedia Station.
• USB - Network share for data copy function via USB ports.
• Web - Network share for Web Server.
• Network Recycle Bin 1 - Default network recycle bin share for deleted files.
Check Volume
1. Choose Disk Management > Volume Management.
2. Click Check Now on the volume to perform check.
