Before setting up logical Volume, you must take note of these limitations:

1. The maximum size of one logical volume is 2PB.
2. The maximum drive that a DS system can manage is 444.
3. The maximum number of physical drives for a single LD (logical drive) is 128.
4. The maximum number of LDs (logical drive) is 32.

Then to configure a LV ( Logical Volume) perfectly to meet your storage space, drive performance and cost requirements and so on, you must take all the following factors into consideration/calculation:

1. The type of logical drive: RAID1, RAID5, RAID6, etc.
2. The number of drives to be used in one LD (logical drive)
3. The number of LDs for a sufficient drive performance
4. The number of needed spare drives
5. The size of the physical drive to work with the composition setup above.

When you apply the needed configuration of those correlated factors mentioned above, you will have a perfect management of LV setup.

For instance, you use 15 pieces of 6 TB NL-SAS drives to form a RAID 6 and apply 24 sets to fulfill performance. In this configuration, you will have 360 drives in one LV (logical volume) and 1684 TB of available space. You can still have some flexibility to set spare drives, join more LDs (logical drive), or even create another LV (Logical Volume) for your future needs.
