For more information about configurations, see the “Disk Configurations” on page 125.
Step Two: Set up Your storage system
Setting up your storage system consists of the following steps:
Installing the Hard Disks
Attaching USB Devices
Connecting the Storage System to the Network
Powering Up the Storage System
Installing the Hard Disks
If you have fewer than four hard disks in your storage system, you might want to add more at this time. You
can add disks later, but changing your disk configuration once the disks contain data might cause data
loss.
To install the hard disks, you need a Phillips head screwdriver.
1. Remove the top hard disk tray from the storage system:
3 Linear Independent disks 1.5 TB No Good
RAID 0 Striping 1.5 TB No High
RAID 5 Striping with parity 1.0 TB Yes Good
4 Linear Independent disks 2.0 TB No Good
RAID 0 Striping 2.0 TB No High
RAID 5 Striping with parity 1.5 TB Yes Good
RAID 5
with Spare
Striping with parity; spare drive
automatically rebuilds a failed
drive 1.0 TB Yes Good
RAID 10 Striping, Mirroring 1.0 TB Yes Good
* Available capacity based on 500-GB drives
Note: The storage system must have at least one SATA hard disk with a capacity of at least 80
GB.
USRobotics strongly recommends that you install all the hard disks that you want to use in
the storage system at this time in order to avoid data loss.
USRobotics also recommends that you use 4 disks of the same size for optimum perfor-
mance.
