Chapter 8 Storage Manager Internal Volumes Table 7 Internal Volumes OPTION Volume DESCRIPTION Allocates all the available space to the volume. Volume on Disk Group Provides better performance. Allows you to create multiple volumes on a disk group. Allows you to customize the size of a volume. RAID Types The following table describes RAID types. Note: RAID 5, RAID 6, RAID 10, and the hot spare option apply to 4-bay NAS devices. Table 8 RAID Types RAID NO. OF TYPE HDD Basic 1 NO. OF HDD ALLOWED TO FAIL 0 JBOD 2-4 0 RAID 0 2-4 RAID 1 2-4 0 (No. of HDD) -1 RAID 5 3-4 1 RAID 6 4 RAID 10 4 2 1 HDD in each RAID 1 group DESCRIPTION CAPACITY Use Basic with one disk. It has no fault tolerance. Use JBOD with two or more disks for maximum capacity. This is just a collection of disks with no fault tolerance. Use RAID 0 with two or four disks for maximum speed and no fault tolerance. Use RAID 1 to create an exact copy of data on one disk to a second disk. Use this with two to four disks to mirror primary data to another disk(s) with high performance. You can add a hot spare to a 2-disk RAID 1. Use RAID 5 with three or four disks to balance performance and hard disk capacity usage with data protection in case of disk failure. You can add a hot spare to a 3-disk RAID 5. Use RAID 6 with four disks for more data protection in case of disk failure. Use RAID 10 with four disks to get better performance than RAID 6, with slightly less data protection. 1 x (HDD size) sum of HDD sizes sum of HDD sizes Smallest HDD size (No. of HDD - 1) x (smallest HDD size) (No. of HDD - 2) x (smallest HDD size) (No. of HDD / 2) x (smallest HDD size) Repair Volumes or Disk Groups If a hard disk in a RAID 1 with a hot spare or a RAID 5 with a hot spare fails, the NAS automatically uses the hot spare to re-build the volume or disk group. Later you can replace the failed hard disk and add the new disk as a hot spare. A hard disk failure in a RAID 1, RAID 5, RAID 6, or RAID 10 degrades the volume or disk group. Replace the failed disk and use the Internal Storage screen's Repair link to repair the volume. Cloud Storage User's Guide 50

Internal Volumes

RAID Types

The following table describes RAID types.

Note: RAID 5, RAID 6, RAID 10, and the hot spare option apply to 4-bay NAS devices.

Repair Volumes or Disk Groups

If a hard disk in a RAID 1 with a hot spare or a RAID 5 with a hot spare fails, the NAS automatically

uses the hot spare to re-build the volume or disk group. Later you can replace the failed hard disk

and add the new disk as a hot spare.

A hard disk failure in a RAID 1, RAID 5, RAID 6, or RAID 10 degrades the volume or disk group.

Replace the failed disk and use the

Internal

Storage

screen’s

Repair

link to repair the volume.
