Drobo B810n Getting Started Guide 9
A shortcut to estimate the capacity available for your data is to omit the largest drive and then, add
the capacity of the remaining drives. If you plan to use Dual Disk Redundancy , then omit the largest
two drives.
Single disk (default) redundancy
# Drives Drive Capacity Usable Protected Capacity *
3 6TB+6TB+6TB = 12TB
4 4TB+6TB+6TB+6TB = 14TB
5 4TB+6TB+6TB+6TB+6TB = 22TB
Dual disk redundancy
# Drives Drive Capacity Usable Protected Capacity *
3 6TB+6TB+6TB = 6TB
4 4TB+4TB+6TB+6TB = 8TB
5 4TB+6TB+6TB+6TB+6TB = 16TB
Notes:
- Actual capacity is often less than what is shown in the examples above due to the different systems
used for rating capacity. This has nothing to do with the Drobo B810n.
- Your Drobo B810n enables you to easily increase storage capacity at any time by simply inserting
additional drives or replacing smaller drives with larger ones.
1.4.4 Using power protection
We recommend using the following power protection with your Drobo B810n:
 An uninterruptible power supply (UPS), which protects against sudden losses in power.

A power surge protector to protect against power surges.
2: Setting Up Drobo B810n
Once you have unpacked your Drobo B810n device from its box and ensured that you meet all the
operating system and hardware requirements, it is time to set up your device for use.
The Drobo B810n shipped out will not have the latest firmware. So, it is recommended to upgrade
the firmware to the latest version before using the device.
