Determining Drive Space Requirements; Using Power Protection - Drobo 5D Getting Started Manual

Determining Drive Space Requirements

In order to protect your data from drive failure, your Drobo 5D requires more space than what you
will use for your data, sometimes as much as double or more the amount of space.
The best way to determine how much usable, protected storage space you will have available for
your data, based on the number and capacity of your drives, is to use our Capacity Calculator at
www.drobo.com/calculator.
A shortcut to estimating the
add the capacity of the remaining drives. If you plan to use Dual Disk Redundancy, omit the
largest two drives. For example:
Single Disk (Default) Redundancy
Dual Disk Redundancy
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 Drobo devices.
Know that all Drobo devices enable you to easily increase storage capacity at any time by
-
simply inserting additional drives or replacing smaller drives with larger ones.

Using Power Protection

We recommend using the following power protection with your Drobo device:
•
An uninterruptible power supply (UPS), which protects against sudden losses in power
•
A power surge protector to protect against power surges
