Checking The Hardware You Need; Selecting Hard Drives - Drobo Pro Getting Started Manual

Notes:
- DroboPro's iSCSI connection supports gigabit Ethernet connections (1000 Mbit/s)
for optimal performance. Although your DroboPro will auto-negotiate the highest
connection speed available to your computer, router or switch, iSCSI does not perform
well at slower speeds.
- You can purchase an add-on gigabit Ethernet adapter card for your computer if
needed. Note, however, that a regular network adapter card is required, as Data
Robotics, Inc., does not support iSCSI-specific cards, or HBA (host bus adapter) cards.

Checking the Hardware You Need

To use your Drobo/Pro/S, you'll need at least two hard drives. If you plan to use Dual Disk
Redundancy, which protects your data against two hard drive failures, you will need at least
three hard drives. This section helps you:
ensure your data is protected

Selecting Hard Drives

You can use hard drives from any manufacturer and with any capacity (the space available
on the hard drive) with your Drobo device.
All Drobo devices support standard 3.5" internal SATA drives. If you are unsure, ask
your administrator or hard drive retailer or manufacturer to verify that your hard drives
meet this standard.
Drobo devices are not compatible with SSD, IDE, SCSI or PATA hard drives.
Warning: Any pre-existing data on the drives will be erased during installation.
