Disk group management

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:

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. A minimum of two drives is required to create a RAID 0 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.

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. A minimum of three hard drives is required to create a RAID 5 array.

Advantages

RAID 5’s strong advantage over RAID 0 is data protection. If one physical drive fails, the parity blocks can be used to rebuild the data on a spare drive. You still have access to all your data, even while the data is being rebuilt on the spare drive. For a configuration that does not include a spare drive, be sure to back up your data to another storage device. Contact customer support concerning the failed drive.

RAID 5 offers read performance that can approach RAID 0. However, write performance is slower because the parity data must also be calculated.

Additionally, you still have much of the storage capacity of a RAID 0 array, based on the total available hard drives and storage capacities. 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 five 10TB hard drives for a total of 50TB. The equation is:

10TB * 4 = 40TB

Disadvantages

If one drive in the array fails, restoring the data by building a replacement drive may take hours, depending on the array’s capacity. If another drive fails during this time, all data in the array is lost.

Identifying a connected Lyve Mobile device using the LED

Lyve Client can identify a connected Lyve Mobile device for you by having it temporarily flash its LED. This is useful if you have a large bank of connected Lyve Mobile devices and you need to identify a particular device.

1. Click on the Devices tab.
2. Hover your cursor over a Lyve Mobile device card and click on the Identify LED icon.

3. Observe the front faces of your devices to spot the one with the flashing purple LED.
4. Click the Identify LED icon a second time to turn off the identification.

Renaming a connected Lyve Mobile device

You can rename connected Lyve Mobile devices.

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

3. Enter a new name for the device.
4. Click Done.

Viewing device details

To view device details:

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

Change a Lyve Mobile device's LED settings

You can turn a Lyve Mobile device's LED on or off and view the device's LED color legend. The Legend shows the definition of each LED color to a specific state.

1. Click on the Devices tab.
2. Click on the card for a connected device.
3. Hover your cursor over the LED card and click on the Edit LED icon.

4. Click on the toggle switch to turn the LED on or off.
5. Click on Show LED Legend to expand the legend.
6. Click Done.

Adding tags to a device

You can add metadata tags to your device.

1. Click on the Devices tab.
2. Click on the card for a connected device.
3. Hover your cursor over the Tags card and click on the Edit icon.

4. Enter a tag in the edit field and press Enter.
5. Continue to enter tags in the edit field, pressing Enter after each entry.
6. When you're finished adding tags, click Done.

Crypto-erasing a Lyve Mobile device

A crypto-erase securely deletes all data on the Lyve Mobile device while keeping your device settings and password intact.

To securely erase your Lyve device, Lyve Client accesses all data on individual drives. Therefore, the RAID must be recreated after the crypto-erase is complete. Recreating the RAID requires an initialization that can take over 24 hours if the Lyve device is not in use. You can use your Lyve device during the initialization but performance will be degraded until it is complete. Also, using the device during an initialization will increase the time for it to complete. To avoid delays in completing the initialization, make certain that the host computer does not go to sleep until it is complete. If the computer goes to sleep, the initialization will be paused until it wakes up.

1. Click on the Devices tab.
2. Click on the card for a connected device.
3. Hover your cursor over the Device Settings card and click on the Erase icon.

4. Click Erase.

Viewing Lyve Mobile disk details and enabling dynamic spare disks

You can view Lyve Mobile device disk details, such as the status of each disk, it's capacity, and its RAID array setting. You can also allow disks that are unassigned to an array to act as a spare for any disk group on the device.

2. Click on the card for a connected device.
3. Hover your cursor over Disks and Spares icon and click on the Inspect icon.

4. (Optional) Click the Enable Dynamic Spares toggle switch.
