Configure Disk Group (RAID)

A disk group is a combination of two or more physical drives that are presented to the operating system as a single device. Drives are combined into different configurations known as ‘RAID levels’. RAID stands for redundant array of independent disks. A RAID level categorizes how data is written to the drives in the array.

The RAID level you choose depends on which storage attributes are most important to you:

Capacity The total amount of data you can store.
Performance The speed at which data is copied
Protection The number of disks that can fail before data is lost

Lyve Mobile Array can be configured as RAID 0 or RAID 5. Both RAID levels offer advantages and disadvantages, described below.

RAID 0

In RAID 0, data is split into blocks that get written across all drives in the array.

Advantages

  • Data is not duplicated across drives. This results in faster transfers and more storage, since the full capacity of all drives can be used to store unique data.
  • Initialization takes only minutes.

Disadvantages

  • RAID 0 lacks data protection. If a single drive fails, all data in the array is lost.

RAID 5

In RAID 5, data is also split into blocks that get written across all hard drives in the array. In addition, a redundant parity block is written for each data block.

Advantages

RAID 5’s strong advantage over RAID 0 is data protection. If one physical drive fails, you still have access to all your data.

 In the event a drive fails, you should immediately copy all your data to another storage device and contact customer support.

Disadvantages

  • RAID 5 offers read performance that can approach RAID 0. However, write performance is slower because the parity data must also be calculated.
  • You still have much of the storage capacity of a RAID 0 array, based on the total available hard drives and storage capacities. However, overall storage capacity is reduced slightly. The equation for determining the storage is:

(The size of the drive with the smallest capacity in the array) * (Total hard drives minus 1)

Example: An array is assigned six 10TB hard drives for a total of 60TB. The equation is:

10TB * 5 = 50TB

  • Initialization may take up to 32 hours for an HDD device.

Change RAID configuration

  1. Click on the Devices tab.
  2. Hover your cursor over a device card and click on the Inspect icon.

  3. If the device is currently configured with a disk group (RAID array), click on the Wrench icon on the disk group volume card:


    4.  If the device is not currently configured with a disk group, scroll down and click Create disk group.

  4. Select a RAID configuration: RAID 5 or RAID 0. Click Next.

  5. Select a volume configuration.

  1. Enter a volume label.
  2. Select a volume format:
    • Lyve Client for windows: NTFS or exFAT
    • Lyve Client for windows: HFS+ or exFAT
  3. Click Confirm.

The volume is displayed on the Device Details page with an amber status icon while the disks are being initialized.
