Selecting Hard Drives
By default, Drobo B1200i is set to run in Dual Disk Redundancy mode, which protects
your data against two simultaneous hard drive failures. Therefore, you will need at
least three hard drives. If, however, you decide to disable Dual Disk Redundancy, you
will need at least two hard drives.
Note: For Drobo B1200i, we recommend that you use at least five high-performance

better striping performance, and also helps distribute loads more effectively.
You can use hard drives from any manufacturer and with any capacity with the Drobo
device. Drobo B1200i supports both the standard 3.5” internal SAS and SATA drives.
Important: You cannot mix SATA and SAS drives at the same time in the same disk
QBDLXJUI%SPCP#J5IFTFUPGIBSEESJWFTZPVMPBEJOUPUIF%SPCPEFWJDFJT

Drobo devices are not compatible with IDE, parallel SCSI, or SATA hard drives.
Warning: Any pre-existing data on the drives will be erased when inserted
into the Drobo B1200i. If you wish to keep the data, copy it to another drive or
medium before using with the Drobo device.

Determining How Much Hard Drive Space You Need
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 capacity available for your data is to omit the largest drive
and then add the capacity of the remaining drives. For Dual Disk Redundancy, omit the
largest two drives. For example:
%VBM%JTL3FEVOEBODZ%FGBVMU
Single Disk Redundancy
Notes:
- Actual capacity could be less than what is shown in the examples above. This has
nothing to do with Drobo devices.
- This is because different disc vendors have slightly differing capacities, and has
nothing to do with Drobo devices..
Selecting Ethernet Cables
Since Drobo B1200i has four Gigabit Ethernet ports, you might need two or up to four
Ethernet cables, depending on how you plan to configure and use Drobo B1200i.

cables with RJ45 connectors.
Using a Switch
If you plan to share Drobo B1200i with more than three servers, you will need to use
a switch; otherwise, a switch is not necessary. Note that when connecting Drobo

Configuring iSCSI Settings for the Drobo B1200i
Before using Drobo B1200i, you will need to configure the settings for its iSCSI data ports.
Network settings include IP addresses for the three iSCSI data ports available on Drobo
B1200i, as well as the related subnet mask. Network settings also include the ability to

You can modify the MTU settings in order to support the use of jumbo frames. Jumbo frames
are those that maintain data transfer rates of more than 1,500 bytes per frame, and can
carry up to 9,000 bytes per frame. Use of jumbo frames minimizes transaction loads, and can
dramatically improve network performance by raising effective bandwidth.
You can also choose to modify settings for the management port.
Before configuring network settings, it is important to know how you plan to set up Drobo
B1200i in your environment. If you haven’t already done so, review options in “Configuration
Options for Drobo B1200i” on page 12.
1. In Drobo Dashboard, make sure Drobo B1200i is selected from the All Drobos page.
2. Click the Device Settings option on the Navigation menu, and click Network.
The Network Settings page opens.
3. Click on one of the iSCSI port icons for which you would like to set or modify network
settings, as needed.
